+		   Doing the BK Thing, Penguin-Style
+
+
+
+
+This set of notes is intended mainly for kernel developers, occasional
+or full-time, but sysadmins and power users may find parts of it useful
+as well.  It assumes at least a basic familiarity with CVS, both at a
+user level (use on the cmd line) and at a higher level (client-server model).
+Due to the author's background, an operation may be described in terms
+of CVS, or in terms of how that operation differs from CVS.
+
+This is -not- intended to be BitKeeper documentation.  Always run
+"bk help <command>" or in X "bk helptool <command>" for reference
+documentation.
+
+
+BitKeeper Concepts
+------------------
+
+In the true nature of the Internet itself, BitKeeper is a distributed
+system.  When applied to revision control, this means doing away with
+client-server, and changing to a parent-child model... essentially
+peer-to-peer.  On the developer's end, this also represents a
+fundamental disruption in the standard workflow of changes, commits,
+and merges.  You will need to take a few minutes to think about
+how to best work under BitKeeper, and re-optimize things a bit.
+In some sense it is a bit radical, because it might described as
+tossing changes out into a maelstrom and having them magically
+land at the right destination... but I'm getting ahead of myself.
+
+Let's start with this progression:
+Each BitKeeper source tree on disk is a repository unto itself.
+Each repository has a parent.
+Each repository contains a set of a changesets ("csets").
+Each cset is one or more changed files, bundled together.
+
+Each tree is a repository, so all changes are checked into the local
+tree.  When a change is checked in, all modified files are grouped
+into a logical unit, the changeset.  Internally, BK links these
+changesets in a tree, representing various converging and diverging
+lines of development.  These changesets are the bread and butter of
+the BK system.
+
+After the concept of changesets, the next thing you need to get used
+to is having multiple copies of source trees lying around.  This -really-
+takes some getting used to, for some people.  Separate source trees
+are the means in BitKeeper by which you delineate parallel lines
+of development, both minor and major.  What would be branches in
+CVS become separate source trees, or "clones" in BitKeeper [heh,
+or Star Wars] terminology.
+
+Clones and changesets are the tools from which most of the power of
+BitKeeper is derived.  As mentioned earlier, each clone has a parent,
+the tree used as the source when the new clone was created.  In a
+CVS-like setup, the parent would be a remote server on the Internet,
+and the child is your local clone of that tree.
+
+Once you have established a common baseline between two source trees --
+a common parent -- then you can merge changesets between those two
+trees with ease.  Merging changes into a tree is called a "pull", and
+is analagous to 'cvs update'.  A pull downloads all the changesets in
+the remote tree you do not have, and merges them.  Sending changes in
+one tree to another tree is called a "push".  Push sends all changes
+in the local tree the remote does not yet have, and merges them.
+
+From these concepts come some initial command examples:
+
+1) bk clone -q http://linux.bkbits.net/linux-2.5 linus-2.5
+Download a 2.5 stock kernel tree, naming it "linus-2.5" in the local dir.
+The "-q" disables listing every single file as it is downloaded.
+
+2) bk clone -ql linus-2.5 alpha-2.5
+Create a separate source tree for the Alpha AXP architecture.
+The "-l" uses hard links instead of copying data, since both trees are
+on the local disk.  You can also replace the above with "bk lclone -q ..."
+
+You only clone a tree -once-.  After cloning the tree lives a long time
+on disk, being updating by pushes and pulls.
+
+3) cd alpha-2.5 ; bk pull http://gkernel.bkbits.net/alpha-2.5
+Download changes in "alpha-2.5" repository which are not present
+in the local repository, and merge them into the source tree.
+
+4) bk -r co -q
+Because every tree is a repository, files must be checked out before
+they will be in their standard places in the source tree.
+
+5)	bk vi fs/inode.c				# example change...
+	bk citool					# checkin, using X tool
+	bk push bk://gkernel@bkbits.net/alpha-2.5	# upload change
+Typical example of a BK sequence that would replace the analagous CVS
+situation,
+	vi fs/inode.c
+	cvs commit
+
+As this is just supposed to be a quick BK intro, for more in-depth
+tutorials, live working demos, and docs, see http://www.bitkeeper.com/
+
+
+
+BK and Kernel Development Workflow
+----------------------------------
+Currently the latest 2.5 tree is available via "bk clone $URL"
+and "bk pull $URL" at http://linux.bkbits.net/linux-2.5
+This should change in a few weeks to a kernel.org URL.
+
+
+A big part of using BitKeeper is organizing the various trees you have
+on your local disk, and organizing the flow of changes among those
+trees, and remote trees.  If one were to graph the relationships between
+a desired BK setup, you are likely to see a few-many-few graph, like
+this:
+
+		    linux-2.5
+		        |
+	       merge-to-linus-2.5
+		 /    |      |
+	        /     |      |
+	vm-hacks  bugfixes  filesys   personal-hacks
+	      \	      |	     |		/
+	       \      |      |         /
+		\     |      |        /
+	         testing-and-validation
+
+Since a "bk push" sends all changes not in the target tree, and
+since a "bk pull" receives all changes not in the source tree, you want
+to make sure you are only pushing specific changes to the desired tree,
+not all changes from "peer parent" trees.  For example, pushing a change
+from the testing-and-validation tree would probably be a bad idea,
+because it will push all changes from vm-hacks, bugfixes, filesys, and
+personal-hacks trees into the target tree.
+
+One would typically work on only one "theme" at a time, either
+vm-hacks or bugfixes or filesys, keeping those changes isolated in
+their own tree during development, and only merge the isolated with
+other changes when going upstream (to Linus or other maintainers) or
+downstream (to your "union" trees, like testing-and-validation above).
+
+It should be noted that some of this separation is not just recommended
+practice, it's actually [for now] -enforced- by BitKeeper.  BitKeeper
+requires that changesets maintain a certain order, which is the reason
+that "bk push" sends all local changesets the remote doesn't have.  This
+separation may look like a lot of wasted disk space at first, but it
+helps when two unrelated changes may "pollute" the same area of code, or
+don't follow the same pace of development, or any other of the standard
+reasons why one creates a development branch.
+
+Small development branches (clones) will appear and disappear:
+
+	-------- A --------- B --------- C --------- D -------
+	          \                                 /
+		   -----short-term devel branch-----
+
+While long-term branches will parallel a tree (or trees), with period
+merge points.  In this first example, we pull from a tree (pulls,
+"\") periodically, such as what occurs when tracking changes in a
+vendor tree, never pushing changes back up the line:
+
+	-------- A --------- B --------- C --------- D -------
+	          \                       \           \
+	           ----long-term devel branch-----------------
+
+And then a more common case in Linux kernel development, a long term
+branch with periodic merges back into the tree (pushes, "/"):
+
+	-------- A --------- B --------- C --------- D -------
+	          \                       \         / \
+	           ----long-term devel branch-----------------
+
+
+
+
+
+Submitting Changes to Linus
+---------------------------
+There's a bit of an art, or style, of submitting changes to Linus.
+Since Linus's tree is now (you might say) fully integrated into the
+distributed BitKeeper system, there are several prerequisites to
+properly submitting a BitKeeper change.  All these prereq's are just
+general cleanliness of BK usage, so as people become experts at BK, feel
+free to optimize this process further (assuming Linus agrees, of
+course).
+
+
+
+0) Make sure your tree was originally cloned from the linux-2.5 tree
+created by Linus.  If your tree does not have this as its ancestor, it
+is impossible to reliably exchange changesets.
+
+
+
+1) Pay attention to your commit text.  The commit message that
+accompanies each changeset you submit will live on forever in history,
+and is used by Linus to accurately summarize the changes in each
+pre-patch.  Remember that there is no context, so
+	"fix for new scheduler changes"
+would be too vague, but
+	"fix mips64 arch for new scheduler switch_to(), TIF_xxx semantics"
+would be much better.
+
+You can and should use the command "bk comment -C<rev>" to update the
+commit text, and improve it after the fact.  This is very useful for
+development: poor, quick descriptions during development, which get
+cleaned up using "bk comment" before issuing the "bk push" to submit the
+changes.
+
+
+
+2) Include an Internet-available URL for Linus to pull from, such as
+
+	Pull from:  http://gkernel.bkbits.net/net-drivers-2.5
+
+
+
+3) Include a summary and "diffstat -p1" of each changeset that will be
+downloaded, when Linus issues a "bk pull".  The author auto-generates
+these summaries using "bk push -nl <parent> 2>&1", to obtain a listing
+of all the pending-to-send changesets, and their commit messages.
+
+It is important to show Linus what he will be downloading when he issues
+a "bk pull", to reduce the time required to sift the changes once they
+are downloaded to Linus's local machine.
+
+IMPORTANT NOTE:  One of the features of BK is that your repository does
+not have to be up to date, in order for Linus to receive your changes.
+It is considered a courtesy to keep your repository fairly recent, to
+lessen any potential merge work Linus may need to do.
+
+
+4) Split up your changes.  Each maintainer<->Linus situation is likely
+to be slightly different here, so take this just as general advice.  The
+author splits up changes according to "themes" when merging with Linus.
+Simultaneous pushes from local development go to special trees which
+exist solely to house changes "queued" for Linus.  Example of the trees:
+
+	net-drivers-2.5 -- on-going net driver maintenance
+	vm-2.5 -- VM-related changes
+	fs-2.5 -- filesystem-related changes
+
+Linus then has much more freedom for pulling changes.  He could (for
+example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their
+changes, but hold off net-drivers-2.5 because of a change that needs
+more discussion.
+
+Other maintainers may find that a single linus-pull-from tree is
+adequate for passing BK changesets to him.
+
+
+
+Frequently Answered Questions
+-----------------------------
+1) How do I change the e-mail address shown in the changelog?
+A. When you run "bk citool" or "bk commit", set environment
+   variables BK_USER and BK_HOST to the desired username
+   and host/domain name.
+
+
+2) How do I use tags / get a diff between two kernel versions?
+A. Pass the tags Linus uses to 'bk export'.
+
+ChangeSets are in a forward-progressing order, so it's pretty easy
+to get a snapshot starting and ending at any two points in time.
+Linus puts tags on each release and pre-release, so you could use
+these two examples:
+
+    bk export -tpatch -hdu -rv2.5.4,v2.5.5 | less
+        # creates patch-2.5.5 essentially
+    bk export -tpatch -du -rv2.5.5-pre1,v2.5.5 | less
+        # changes from pre1 to final
+
+A tag is just an alias for a specific changeset... and since changesets
+are ordered, a tag is thus a marker for a specific point in time (or
+specific state of the tree).

+<para>
+The journalling layer is  easy to use. You need to 
+first of all create a journal_t data structure. There are
+two calls to do this dependent on how you decide to allocate the physical
+media on which the journal resides. The journal_init_inode() call 
+is for journals stored in filesystem inodes, or the journal_init_dev()
+call can be use for journal stored on a raw device (in a continuous range 
+of blocks). A journal_t is a typedef for a struct pointer, so when
+you are finally finished make sure you call journal_destroy() on it
+to free up any used kernel memory.
+</para>
+
+<para>
+Once you have got your journal_t object you need to 'mount' or load the journal
+file, unless of course you haven't initialised it yet - in which case you
+need to call journal_create().
+</para>
+
+<para>
+Most of the time however your journal file will already have been created, but
+before you load it you must call journal_wipe() to empty the journal file.
+Hang on, you say , what if the filesystem wasn't cleanly umount()'d . Well, it is the 
+job of the client file system to detect this and skip the call to journal_wipe().
+</para>
+
+<para>
+In either case the next call should be to journal_load() which prepares the
+journal file for use. Note that journal_wipe(..,0) calls journal_skip_recovery() 
+for you if it detects any outstanding transactions in the journal and similarly
+journal_load() will call journal_recover() if necessary.
+I would advise reading fs/ext3/super.c for examples on this stage.
+[RGG: Why is the journal_wipe() call necessary - doesn't this needlessly 
+complicate the API. Or isn't a good idea for the journal layer to hide 
+dirty mounts from the client fs]
+</para>
+
+<para>
+Now you can go ahead and start modifying the underlying 
+filesystem. Almost.
+</para>
+
+
+<para>
+
+You still need to actually journal your filesystem changes, this
+is done by wrapping them into transactions. Additionally you
+also need to wrap the modification of each of the the buffers
+with calls to the journal layer, so it knows what the modifications
+you are actually making are. To do this use  journal_start() which
+returns a transaction handle.
+</para>
+
+<para>
+journal_start()
+and its counterpart journal_stop(), which indicates the end of a transaction
+are nestable calls, so you can reenter a transaction if necessary,
+but remember you must call journal_stop() the same number of times as
+journal_start() before the transaction is completed (or more accurately
+leaves the the update phase). Ext3/VFS makes use of this feature to simplify 
+quota support.
+</para>
+
+<para>
+Inside each transaction you need to wrap the modifications to the
+individual buffers (blocks). Before you start to modify a buffer you
+need to call journal_get_{create,write,undo}_access() as appropriate,
+this allows the journalling layer to copy the unmodified data if it
+needs to. After all the buffer may be part of a previously uncommitted
+transaction. 
+At this point you are at last ready to modify a buffer, and once
+you are have done so you need to call journal_dirty_{meta,}data().
+Or if you've asked for access to a buffer you now know is now longer 
+required to be pushed back on the device you can call journal_forget()
+in much the same way as you might have used bforget() in the past.
+
+</para>
+
+
+
+<para>
+A journal_flush() may be called at any time to commit and checkpoint
+all your transactions.
+</para>
+<para>
+
+Then at umount time , in your put_super() (2.4) or write_super() (2.5)
+you can then call journal_destroy() to clean up your in-core journal object.
+</para>
+
+
+<para>
+Unfortunately there a couple of ways the journal layer can cause a deadlock.
+The first thing to note is that each task can only have
+a single outstanding transaction at any one time, remember nothing
+commits until the outermost journal_stop(). This means
+you must complete the transaction at the end of each file/inode/address
+etc. operation you perform, so that the journalling system isn't re-entered
+on another journal. Since transactions can't be nested/batched 
+across differing journals, and another filesystem other than
+yours (say ext3) may be modified in a later syscall.
+</para>
+<para>
+
+The second case to bear in mind is that journal_start() can 
+block if there isn't enough space in the journal for your transaction 
+(based on the passed nblocks param) - when it blocks it merely(!) needs to
+wait for transactions to complete and be committed from other tasks, 
+so essentially we are waiting for journal_stop(). So to avoid 
+deadlocks you must treat journal_start/stop() as if they
+were semaphores and include them in your semaphore ordering rules to prevent 
+deadlocks. Note that journal_extend() has similar blocking behaviour to
+journal_start() so you can deadlock here just as easily as on journal_start().
+</para>
+<para>
+
+Try to reserve the right number of blocks the first time. ;-).
+</para>
+<para>
+Another wriggle to watch out for is your on-disk block allocation strategy.
+why? Because, if you undo a delete, you need to ensure you haven't reused any
+of the freed blocks in a later transaction. One simple way of doing this
+is make sure any blocks you allocate only have checkpointed transactions
+listed against them. Ext3 does this in ext3_test_allocatable(). 
+</para>
+
+<para>
+Lock is also providing through journal_{un,}lock_updates(),
+ext3 uses this when it wants a window with a clean and stable fs for a moment.
+eg. 
+<programlisting>
+
+	journal_lock_updates() //stop new stuff happening..
+	journal_flush()        // checkpoint everything.
+	..do stuff on stable fs
+	journal_unlock_updates() // carry on with filesystem use.
+</programlisting>
+
+The opportunities for abuse and DOS attacks with this should be obvious,
+if you allow unprivileged userspace to trigger codepaths containing these
+calls.
+
+<para>
+</sect1>
+<sect1>
+<title>Summary</title>
+<para>
+Using the journal is a matter of wrapping the different context changes,
+being each mount, each modification (transaction) and each changed buffer
+to tell the journalling layer about them.
+
+Here is a some pseudo code to give you an idea of how it works, as
+an example.
+<programlisting>
+  journal_t* my_jnrl = journal_create();
+  journal_init_{dev,inode}(jnrl,...)

+  journal_load();

+                            userspace*/
+
+          handle_t * xct=journal_start(my_jnrl);
+          foreach(bh) {
+                journal_get_{create,write,undo}_access(xact,bh);
+                if ( myfs_modify(bh) ) { /* returns true 
+                                        if makes changes */
+                           journal_dirty_{meta,}data(xact,bh);
+                } else {
+                           journal_forget(bh);

+
+WARNING
+=======
+Make sure you understand that this is alpha software.  This means that the
+implementation is neither complete nor well-tested. 
+
+I DISCLAIM ALL RESPONSIBILTY FOR ANY POSSIBLE BAD EFFECTS OF THIS CODE!

+Or the GNU website: <http://www.gnu.org/licenses/licenses.html>
+
+AUTHOR
+=====
+Current maintainer: Will Dyson <will_dyson@pobox.com>
+Has been working on the code since Aug 13, 2001. See the changelog for details.
+
+Original Author: Makoto Kato <m_kato@ga2.so-net.ne.jp>
+His orriginal code can still be found at: <http://hp.vector.co.jp/authors/VA008030/bfs/>
+Does anyone know of a more current email address for Makoto? He doesn't respond
+to the address given above...
+
+WHAT IS THIS DRIVER?
+==================
+This module implements the native filesystem of BeOS <http://www.be.com/>
+for the linux 2.4.1 and later kernels. Currently it is a read-only implementation.
+
+Which is it, BFS or BEFS?
+================
+Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS". 
+But Unixware Boot Filesystem is called bfs, too. And they are already in the
+kernel.
+Because of this nameing conflict, on Linux the BeOS filesystem is called befs.
+
+HOW TO INSTALL
+==============
+step 1.  Install the BeFS  patch into the source code tree of linux.
+
+Apply the patchfile to your kernel source tree.
+Assuming that your kernel source is in /foo/bar/linux and the patchfile is called
+patch-befs-xxx, you would do the following:
+
+	cd /foo/bar/linux
+	patch -p1 < /path/to/patch-befs-xxx
+
+if the patching step fails (i.e. there are rejected hunks), you can try to
+figure it out yourself (it shouldn't be hard), or mail the maintainer 
+(Will Dyson <will_dyson@pobox.com>) for help.
+
+step 2.  Configuretion & make kernel
+
+The linux kernel has many compile-time options. Most of them are beyond the
+scope of this document. I suggest the Kernel-HOWTO document as a good general
+reference on this topic. <http://www.linux.com/howto/Kernel-HOWTO.html>
+
+However, to use the BeFS module, you must enable it at configure time.
+
+	cd /foo/bar/linux
+	make menuconfig (or xconfig)
+
+The BeFS module is not a standard part of the linux kernel, so you must first
+enable support for experimental code under the "Code maturity level" menu.
+
+Then, under the "Filesystems" menu will be an option called "BeFS filesystem (experimental)",
+or something like that. Enable that option (it is fine to make it a module).
+
+Save your kernel configuration and then build your kernel.
+
+step 3.  Install
+
+See the kernel howto <http://www.linux.com/howto/Kernel-HOWTO.html> for
+instructions on this critical step.
+
+USING BFS
+=========
+To use the BeOS filesystem, use filesystem type 'befs'.
+
+ex)
+    mount -t befs /dev/fd0 /beos
+
+MOUNT OPTIONS
+=============
+uid=nnn        All files in the partition will be owned by user id nnn.
+gid=nnn	       All files in the partition will be in group nnn.
+iocharset=xxx  Use xxx as the name of the NLS translation table.
+debug          The driver will output debugging information to the syslog.
+
+HOW TO GET LASTEST VERSION
+==========================
+
+The latest version is currently available at:
+<http://befs-driver.sourceforge.net/>
+
+ANY KNOWN BUGS?
+===========
+As of Jan 20, 2002:

-
-The value  in  inode-max  denotes  the  maximum number of inode handlers. This

 --- 7.1 Subdirectories
 
-    ALL_SUB_DIRS, SUB_DIRS, MOD_IN_SUB_DIRS, MOD_SUB_DIRS
+A Makefile is only responsible for building objects in its own
+directory. Files in subdirectories should be taken care of by
+Makefiles in the these subdirs. The build system will automatically
+invoke make recursively in subdirectories, provided you let it know of
+them.
 
-	$(ALL_SUB_DIRS) is an unconditional list of *all* the
-	subdirectories in a given directory.  This list should not depend
-	on the kernel configuration.
-
-	$(SUB_DIRS) is a list of subdirectories which may contribute code
-	to vmlinux.  This list may depend on the kernel configuration.
-
-	$(MOD_SUB_DIRS) and $(MOD_IN_SUB_DIRS) are lists of subdirectories
-	which may build kernel modules.  Both names have exactly the
-	same meaning.  (In version 2.2 and earlier kernels, these
-	variables had different meanings -- hence the different names).
+To do so, use the subdir-{y,m,n,} variables:
 
-	For new code, $(MOD_SUB_DIRS) is recommended and $(MOD_IN_SUB_DIRS)
-	is deprecated.

 --- 7.2 Object file goals
 
-    O_TARGET, O_OBJS, OX_OBJS
+    O_TARGET, obj-y
 
-	The subdirectory Makefile specifies object files for vmlinux in
-	the lists $(O_OBJS) and $(OX_OBJS).  These lists depend on the
-	kernel configuration.
-
-	The "X" in "OX_OBJS" stands for "eXport".  Files in $(OX_OBJS)
-	may use the EXPORT_SYMBOL macro to define public symbols which
-	loadable kernel modules can see.  Files in $(O_OBJS) may not use
-	EXPORT_SYMBOL (and you will get a funky error message if you try).
-
-	[Yes, it's kludgy to do this by hand.  Yes, you can define all
-	your objects as $(OX_OBJS) whether they define symbols or not;
-	but then you will notice a lot of extra compiles when you edit
-	any source file.  Blame CONFIG_MODVERSIONS for this.]
-
-	Data that is passed to other objects via registration functions
-	(e.g. pci_register_driver, pm_register) does not need to be marked
-	as EXPORT_SYMBOL.  The objects that pass data via registration
-	functions do not need to be marked as OX_OBJS, unless they also have
-	exported symbols.
-
-	Rules.make compiles all the $(O_OBJS) and $(OX_OBJS) files.
-	It then calls "$(LD) -r" to merge these files into one .o file
-	with the name $(O_TARGET).  This $(O_TARGET) name also appears
-	in the top Makefile.
-
-	The order of files in $(O_OBJS) and $(OX_OBJS) is significant.
-	All $(OX_OBJS) files come first, in the order listed, followed by
-	all $(O_OBJS) files, in the order listed.  Duplicates in the lists
-	are allowed: the first instance will be linked into $(O_TARGET)
-	and succeeding instances will be ignored.  (Note: Rules.make may
-	emit warning messages for duplicates, but this is harmless).
+	The subdirectory Makefile specifies object files for vmlinux
+	in the lists $(obj-y).  These lists depend on the kernel
+	configuration.
 
-	Example:
+	Rules.make compiles all the $(obj-y) files.  It then calls
+	"$(LD) -r" to merge these files into one .o file with the name
+	$(O_TARGET).  This $(O_TARGET) is later linked into vmlinux by 
+	a parent Makefile.
 
-		# arch/alpha/kernel/Makefile
-		O_TARGET := kernel.o
-		O_OBJS   := entry.o traps.o process.o osf_sys.o irq.o \
-			    irq_alpha.o signal.o setup.o ptrace.o time.o \
-			    semaphore.o
-		OX_OBJS  := alpha_ksyms.o
+	The order of files in $(obj-y) is significant.  Duplicates in
+	the lists are allowed: the first instance will be linked into
+	$(O_TARGET) and succeeding instances will be ignored.
 
-		ifdef CONFIG_SMP
-		O_OBJS   += smp.o irq_smp.o
-		endif
+	Link order is significant, because certain functions
+	(module_init() / __initcall) will be called during boot in the
+	order they appear. So keep in mind that changing the link
+	order may e.g.  change the order in which your SCSI
+	controllers are detected, and thus you disks are renumbered.
 
-		ifdef CONFIG_PCI
-		O_OBJS   += pci.o pci_iommu.o
-		endif
-
-	Even if a subdirectory Makefile has an $(O_TARGET), the .config
-	options still control whether or not its $(O_TARGET) goes into
-	vmlinux.  See the $(M_OBJS) example below.
-
-	Sometimes the ordering of all $(OX_OBJS) files before all
-	$(O_OBJS) files can be a problem, particularly if both
-	$(O_OBJS) files and $(OX_OBJS) files contain __initcall
-	declarations where order is important.   To avoid this imposed
-	ordering, the use of $(OX_OBJS) can be dropped altogether and
-	$(MIX_OBJS) used instead.
-
-	If this approach is used, then:
-	 - All objects to be linked into vmlinux should be listed in
-	   $(O_OBJS) in the desired order.
-	 - All objects to be created as modules should be listed in
-	   $(M_OBJS)
-	 - All objects that export symbols should also be listed in
-	   $(MIX_OBJS).
-
-	This has the same effect as maintaining the
-	exported/non-exported split, except that there is more control
-	over the ordering of object files in vmlinux.

+	    # Makefile for the kernel ISDN subsystem and device drivers.
 
---- 7.3 Library file goals
+	    # The target object and module list name.
 
-    L_TARGET, L_OBJS, LX_OBJS
+	    O_TARGET        := vmlinux-obj.o
 
-	These names are similar to the O_* names.  Once again, $(L_OBJS)
-	and $(LX_OBJS) specify object files for the resident kernel;
-	once again, the lists depend on the current configuration; and
-	once again, the files that call EXPORT_SYMBOL go on the "X" list.
-
-	The difference is that "L" stands for "Library".  After making
-	$(L_OBJS) and $(LX_OBJS), Rules.make uses the "$(AR) rcs" command
-	to put these files into an archive file (a library) with the
-	name $(L_TARGET).  This name also appears in the top Makefile.
+	    # Each configuration option enables a list of files.
 
-	Example:
+	    obj-$(CONFIG_ISDN)                      += isdn.o
+	    obj-$(CONFIG_ISDN_PPP_BSDCOMP)          += isdn_bsdcomp.o
 
-		# arch/i386/lib/Makefile
-		L_TARGET = lib.a
-		L_OBJS  = checksum.o old-checksum.o delay.o \
-			usercopy.o getuser.o putuser.o iodebug.o
+	    # The global Rules.make.
 
-		ifdef CONFIG_X86_USE_3DNOW
-		L_OBJS += mmx.o
-		endif
+	    include $(TOPDIR)/Rules.make
 
-		ifdef CONFIG_HAVE_DEC_LOCK
-		L_OBJS += dec_and_lock.o
-		endif
+--- 7.3 Library file goals
 
-	The order of files in $(L_OBJS) and $(LX_OBJS) is not significant.
-	Duplicates in the lists are allowed.  (Note: Rules.make may emit
-	warning messages for duplicates, but this is harmless).
-
-	A subdirectory Makefile can specify either an $(O_TARGET),
-	an $(L_TARGET), or both.  Here is a discussion of the differences.
-
-	All of the files in an $(O_TARGET) are guaranteed to appear in
-	the resident vmlinux image.  In an $(L_TARGET), only the files
-	that satisfy undefined symbol references from other files will
-	appear in vmlinux.
-
-	In a conventional link process, the linker processes some
-	object files and creates a list of unresolved external symbols.
-	The linker then looks in a set of libraries to resolve these
-	symbols.  Indeed, the Linux kernel used to be linked this way,
-	with the bulk of the code stored in libraries.
-
-	But vmlinux contains two types of object files that cannot be
-	fetched out of libraries this way:
-
-	    (1) object files that are purely EXPORT_SYMBOL definitions
-	    (2) object files that use module_init or __initcall initializers
-		(instead of an initialization routine called externally)
-
-	These files contain autonomous initializer sections which provide
-	code and data without being explicitly called.	If these files
-	were stored in $(L_TARGET) libraries, the linker would fail
-	to include them in vmlinux.  Thus, most subdirectory Makefiles
-	specify an $(O_TARGET) and do not use $(L_TARGET).
-
-	Other considerations: $(O_TARGET) leads to faster re-link times
-	during development activity, but $(L_TARGET) gives better error
-	messages for unresolved symbols.
+    L_TARGET
 
+	Instead of building an O_TARGET object file, you may also
+	build an archive which again contains objects listed in
+	$(obj-y). This is normally not necessary and only used in
+	the lib, arch/$(ARCH)/lib directories.
 
 
 --- 7.4 Loadable module goals
 
-    M_OBJS, MX_OBJS
+    obj-m
 
-	$(M_OBJS) and $(MX_OBJS) specify object files which are built
-	as loadable kernel modules.  As usual, the "X" in $(MX_OBJS)
-	stands for "eXport"; source files that use EXPORT_SYMBOL must
-	appear on an $(MX_OBJS) list.
+	$(obj-m) specify object files which are built as loadable
+	kernel modules.
 
 	A module may be built from one source file or several source
-	files.	In the case of one source file, the subdirectory
-	Makefile simply adds the file to either $(M_OBJS) or $(MX_OBJS),
-	as appropriate.
+	files. In the case of one source file, the subdirectory
+	Makefile simply adds the file to $(obj-m)
 
 	Example:
 
-		# drivers/net/irda/Makefile
-		ifeq ($(CONFIG_IRTTY_SIR),y)
-		L_OBJS += irtty.o
-		else
-		  ifeq ($(CONFIG_IRTTY_SIR),m)
-		  M_OBJS += irtty.o
-		  endif
-		endif
+	    obj-$(CONFIG_ISDN_PPP_BSDCOMP)          += isdn_bsdcomp.o
 
-		ifeq ($(CONFIG_IRPORT_SIR),y)
-		LX_OBJS += irport.o
-		else
-		  ifeq ($(CONFIG_IRPORT_SIR),m)
-		  MX_OBJS += irport.o
-		  endif
-		endif
+	If a kernel module is built from several source files, you specify
+	that you want to build a module in the same way as above.
 
-	If a kernel module is built from several source files, there
-	are two ways to specify the set of source files.  One way is to
-	build a single module for the entire subdirectory.  This way is
-	popular in the file system and network protocol stacks.
+	However, the build system of course needs to know which the parts
+	are that you want to build your module of, so you have to tell it
+	by setting an $(<module_name>-objs) variable.
 
 	Example:
 
-		# fs/ext2/Makefile
-		O_TARGET := ext2.o
-		O_OBJS   := acl.o balloc.o bitmap.o dir.o file.o fsync.o \
-			    ialloc.o inode.o ioctl.o namei.o super.o symlink.o \
-			    truncate.o
-		M_OBJS   := $(O_TARGET)
-
-	In this example, the module name will be ext2.o.  Because this
-	file has the same name has $(O_TARGET), Rules.make will use
-	the $(O_TARGET) rule to build ext2.o: it will run "$(LD) -r"
-	on the list of $(O_OBJS) files.
-
-	Note that this subdirectory Makefile defines both an $(O_TARGET)
-	and an $(M_OBJS).  The control code, up in fs/Makefile, will
-	select between these two.  If CONFIG_EXT2_FS=y, then fs/Makefile
-	will build $(O_TARGET); and if CONFIG_EXT_FS=m, then fs/Makefile
-	will build $(M_OBJS) instead.  (Yes, this is a little delicate
-	and a little confusing).
+	    obj-$(CONFIG_ISDN)                      += isdn.o
+
+	    isdn-objs := isdn_net.o isdn_tty.o isdn_v110.o isdn_common.o
+
+	In this example, the module name will be isdn.o. Rules.make
+	will compile the objects listed in $(isdn-objs) and then run
+	"$(LD) -r" on the list of these files to generate isdn.o
+
+	Note: Of course, when you are building objects into the kernel,
+	the syntax above will also work. So, if you have CONFIG_ISDN=y,
+	the build system will build an isdn.o for you out of the individual
+	parts and then link this into the $(O_TARGET), as you'd expect.
+
 
+--- 7.5 Objects which export symbols
 
+    export-objs
+
+	When using loadable modules, not every global symbol in the
+	kernel / other modules is automatically available, only those
+	explicitly exported are available for your module.
 
---- 7.5 Multi-part modules
-
-    MI_OBJS, MIX_OBJS
-
-	Some kernel modules are composed of several object files
-	linked together, but do not include every object file in their
-	subdirectory.  $(MI_OBJS) and $(MIX_OBJS) are for this case.
-
-	"M" stands for Module.
-	"I" stands for Intermediate.
-	"X", as usual, stands for "eXport symbol".
+	To make a symbol available for use in modules, to "export" it,
+	use the EXPORT_SYMBOL(<symbol>) directive in your source. In
+	addition, you need to list all object files which export symbols
+	(i.e. their source contains an EXPORT_SYMBOL() directive) in the
+	Makefile variable $(export-objs).
 
 	Example:
 
-		# drivers/sound/Makefile
-		gus-objs  := gus_card.o gus_midi.o gus_vol.o gus_wave.o ics2101.o
-		pas2-objs := pas2_card.o pas2_midi.o pas2_mixer.o pas2_pcm.o
-		sb-objs	  := sb_card.o
-
-		gus.o: $(gus-objs)
-			$(LD) -r -o $@ $(gus-objs)
-
-		pas2.o: $(pas2-objs)
-			$(LD) -r -o $@ $(pas2-objs)
-
-		sb.o: $(sb-objs)
-			$(LD) -r -o $@ $(sb-objs)
-
-	The kernel modules gus.o, pas2.o, and sb.o are the *composite
-	files*.  The object files gus_card.o, gus_midi.o, gus_vol.o,
-	gus_wave.o, ics2101.o, pas2_card.o, pas2_midi.o, pas2_mixer.o,
-	pas2_pcm.o, and sb_card.o are *component files*.  The component
-	files are also called *intermediate files*.
-
-	In another part of drivers/sound/Makefile (not shown), all of
-	the component files are split out.  For the resident drivers:
-	the component object files go onto $(O_OBJS) and $(OX_OBJS)
-	lists, depending on whether they export symbols or not; and the
-	composite files are never built.  For the kernel modules: the
-	component object files go onto $(MI_OBJS) and $(MIX_OBJS);
-	the composite files go onto $(M_OBJS).
-
-	The subdirectory Makefile must also specify the linking rule
-	for a multi-object-file module:
-
-		# drivers/sound/Makefile
-
-		gus.o: $(gus-objs)
-			$(LD) -r -o $@ $(gus-objs)
-
-		pas2.o: $(pas2-objs)
-			$(LD) -r -o $@ $(pas2-objs)
-
-		sb.o: $(sb-objs)
-			$(LD) -r -o $@ $(sb-objs)
-
-
-	As is mentioned in section 7.2 ("Object file goals"),
-	$(MIX_OBJS) can also be used simply to list all objects that
-	export any symbols.  If this approach is taken, then
-	$(O_OBJS), $(L_OBJS), $(M_OBJS) and $(MI_OBJS) should simply
-	lists all of the vmlinux object files, library object files,
-	module object files and intermediate module files
-	respectively.  Duplication between $(MI_OBJS) and $(MIX_OBJS)
-	is not a problem.
+	    # Objects that export symbols.
+

-=== 9 Compatibility with Linux Kernel 2.2
-
-Most of the information in this document also applies to 2.2, although
-there is no indication of which things have changed when.  Here are some
-hints for writing subdirectory Makefiles that are compatible with Linux
-kernel 2.2.
-
-You can write either an old-style Makefile or a new-style Makefile
-with a boilerplate adapter section.  See the 2.2 version of
-drivers/sound/Makefile for a copy of the boilerplate code.
-
-In 2.2, Rules.make makes a distinction between $(MOD_SUB_DIRS)
-and $(MOD_IN_SUB_DIRS).  If you have a single directory with no
-subdirectories, this will not matter to you.  If you have a whole
-tree, then you need to know the difference between $(MOD_SUB_DIRS)
-and $(MOD_IN_SUB_DIRS).  For example code: $(MOD_SUB_DIRS) is used
-extensively in fs/Makefile; $(MOD_IN_SUB_DIRS) is used extensively in
-drivers/net/Makefile.
-
-If you are already using MOD_LIST_NAME, go ahead and keep using it.
-If you don't already have a MOD_LIST_NAME, go ahead and keep not using
-one; your module will be a 'misc' module in 2.2.
-
-Assembly language rules were a mess in 2.2.  If you have assembly language
-files, this author recommends that you write your own explicit rules
-for each file by name.

+            LDM - Logical Disk Manager (Dynamic Disks)
+            ------------------------------------------
+
+Overview
+--------
+
+Windows 2000 and XP use a new partitioning scheme.  It is a complete
+replacement for the MSDOS style partitions.  It stores its information in a
+1MiB journalled database at the end of the physical disk.  The size of
+partitions is limited only by disk space.  The maximum number of partitions is
+nearly 2000.
+
+Any partitions created under the LDM are called "Dynamic Disks".  There are no
+longer any primary or extended partitions.  Normal MSDOS style partitions are
+now known as Basic Disks.
+
+If you wish to use Spanned, Striped, Mirrored or RAID 5 Volumes, you must use
+Dynamic Disks.  The journalling allows Windows to make changes to these
+partitions and filesystems without the need to reboot.
+
+Once the LDM driver has divided up the disk, you can use the MD driver to
+assemble any multi-partition volumes, e.g.  Stripes, RAID5.
+
+To prevent legacy applications from repartitioning the disk, the LDM creates a
+dummy MSDOS partition containing one disk-sized partition.
+
+
+Example
+-------
+
+Below we have a 50MiB disk, divided into seven partitions.
+N.B.  The missing 1MiB at the end of the disk is where the LDM database is
+      stored.
+
+  Device | Offset Bytes  Sectors  MiB | Size   Bytes  Sectors  MiB
+  -------+----------------------------+---------------------------
+  hda    |            0        0    0 |     52428800   102400   50
+  hda1   |     51380224   100352   49 |      1048576     2048    1
+  hda2   |        16384       32    0 |      6979584    13632    6
+  hda3   |      6995968    13664    6 |     10485760    20480   10
+  hda4   |     17481728    34144   16 |      4194304     8192    4
+  hda5   |     21676032    42336   20 |      5242880    10240    5
+  hda6   |     26918912    52576   25 |     10485760    20480   10
+  hda7   |     37404672    73056   35 |     13959168    27264   13
+
+The LDM Database may not store the partitions in the order that they appear on
+disk, but the driver will sort them.
+
+When Linux boots, you will see something like:
+
+Partition check:
+  hda: [LDM] hda1 hda2 hda3 hda4 hda5 hda6 hda7
+
+
+Compiling LDM Support
+---------------------
+
+To enable LDM, choose the following two options: 
+
+  "Advanced partition selection" CONFIG_PARTITION_ADVANCED
+  "Windows Logical Disk Manager (Dynamic Disk) support" CONFIG_LDM_PARTITION
+
+If you believe the driver isn't working as it should, you can enable the extra
+debugging code.  This will produce a LOT of output.  The option is:
+
+  "Windows LDM extra logging" CONFIG_LDM_DEBUG
+
+N.B. The partition code cannot be compiled as a module.
+
+As with all the partition code, if the driver doesn't see signs of its type of
+partition, it will pass control to another driver, so there is no harm in
+enabling it.
+
+If you have Dynamic Disks but don't enable the driver, then all you will see
+is a dummy MSDOS partition filling the whole disk.  You won't be able to mount
+any of the volumes on the disk.
+
+
+Booting
+-------
+
+If you enable LDM support, then lilo is capable of booting from any of the
+discovered partitions.  However, grub does not understand the LDM partitioning
+and cannot boot from a Dynamic Disk.
+
+
+More Documentation
+------------------
+
+There is an Overview of the LDM online together with complete Technical
+Documentation.  It can also be downloaded in html.

+Introduction to NAPI
+====================
+
+NAPI is a proven (www.cyberus.ca/~hadi/usenix-paper.tgz) technique
+to improve network performance on Linux. For more details please
+read that paper.
+NAPI provides a "inherent mitigation" which is bound by system capacity
+as can be seen from the following data collected by Robert on Gigabit 
+ethernet (e1000):
+
+ Psize    Ipps       Tput     Rxint     Txint    Done     Ndone
+ ---------------------------------------------------------------
+   60    890000     409362        17     27622        7     6823
+  128    758150     464364        21      9301       10     7738
+  256    445632     774646        42     15507       21    12906

+ 
+
+Legend:
+"Ipps" stands for input packets per second. 
+"Tput" == packets out of total 1M that made it out.
+"txint" == transmit completion interrupts seen
+"Done" == The number of times that the poll() managed to pull all
+packets out of the rx ring. Note from this that the lower the
+load the more we could clean up the rxring
+"Ndone" == is the converse of "Done". Note again, that the higher
+the load the more times we couldnt clean up the rxring.
+
+Observe that:
+when the NIC receives 890Kpackets/sec only 17 rx interrupts are generated. 
+The system cant handle the processing at 1 interrupt/packet at that load level. 
+At lower rates on the other hand, rx interrupts go up and therefore the
+interrupt/packet ratio goes up (as observable from that table). So there is
+possibility that under low enough input, you get one poll call for each
+input packet caused by a single interrupt each time. And if the system 
+cant handle interrupt per packet ratio of 1, then it will just have to 
+chug along ....
+
+
+0) Prerequisites:
+==================
+A driver MAY continue using the old 2.4 technique for interfacing
+to the network stack and not benefit from the NAPI changes.
+NAPI additions to the kernel do not break backward compatibility.
+NAPI, however, requires the following features to be available:
+
+A) DMA ring or enough RAM to store packets in software devices.
+
+B) Ability to turn off interrupts or maybe events that send packets up 
+the stack.
+
+NAPI processes packet events in what is known as dev->poll() method.
+Typically, only packet receive events are processed in dev->poll(). 
+The rest of the events MAY be processed by the regular interrupt handler 
+to reduce processing latency (justified also because there are not that 
+many of them).
+Note, however, NAPI does not enforce that dev->poll() only processes 
+receive events. 
+Tests with the tulip driver indicated slightly increased latency if
+all of the interrupt handler is moved to dev->poll(). Also MII handling
+gets a little trickier.
+The example used in this document is to move the receive processing only
+to dev->poll(); this is shown with the patch for the tulip driver.
+For an example of code that moves all the interrupt driver to 
+dev->poll() look at the ported e1000 code.
+
+There are caveats that might force you to go with moving everything to 
+dev->poll(). Different NICs work differently depending on their status/event 
+acknowledgement setup. 
+There are two types of event register ACK mechanisms.
+	I)  what is known as Clear-on-read (COR).
+	when you read the status/event register, it clears everything!
+	The natsemi and sunbmac NICs are known to do this.
+	In this case your only choice is to move all to dev->poll()
+
+	II) Clear-on-write (COW)
+	 i) you clear the status by writting a 1 in the bit-location you want.
+		These are the majority of the NICs and work the best with NAPI.
+		Put only receive events in dev->poll(); leave the rest in
+		the old interrupt handler.
+	 ii) whatever you write in the status register clears every thing ;->
+		Cant seem to find any supported by Linux which do this. If
+		someone knows such a chip email us please.
+		Move all to dev->poll()
+
+C) Ability to detect new work correctly.
+NAPI works by shutting down event interrupts when theres work and
+turning them on when theres none. 
+New packets might show up in the small window while interrupts were being 
+re-enabled (refer to appendix 2).  A packet might sneak in during the period 
+we are enabling interrupts. We only get to know about such a packet when the 
+next new packet arrives and generates an interrupt. 
+Essentially, there is a small window of opportunity for a race condition
+which for clarity we'll refer to as the "rotting packet".
+
+This is a very important topic and appendix 2 is dedicated for more 
+discussion.
+
+Locking rules and environmental guarantees
+==========================================
+
+-Guarantee: Only one CPU at any time can call dev->poll(); this is because
+only one CPU can pick the initial interrupt and hence the initial
+netif_rx_schedule(dev);
+- The core layer invokes devices to send packets in a round robin format.
+This implies receive is totaly lockless because of the guarantee only that 
+one CPU is executing it.
+-  contention can only be the result of some other CPU accessing the rx
+ring. This happens only in close() and suspend() (when these methods
+try to clean the rx ring); 
+****guarantee: driver authors need not worry about this; synchronization 
+is taken care for them by the top net layer.
+-local interrupts are enabled (if you dont move all to dev->poll()). For 
+example link/MII and txcomplete continue functioning just same old way. 
+This improves the latency of processing these events. It is also assumed that 
+the receive interrupt is the largest cause of noise. Note this might not 
+always be true. 
+[according to Manfred Spraul, the winbond insists on sending one 
+txmitcomplete interrupt for each packet (although this can be mitigated)].
+For these broken drivers, move all to dev->poll().
+
+For the rest of this text, we'll assume that dev->poll() only
+processes receive events.
+
+new methods introduce by NAPI
+=============================
+
+a) netif_rx_schedule(dev)
+Called by an IRQ handler to schedule a poll for device
+
+b) netif_rx_schedule_prep(dev)
+puts the device in a state which allows for it to be added to the
+CPU polling list if it is up and running. You can look at this as
+the first half of  netif_rx_schedule(dev) above; the second half
+being c) below.
+
+c) __netif_rx_schedule(dev)
+Add device to the poll list for this CPU; assuming that _prep above
+has already been called and returned 1.
+
+d) netif_rx_reschedule(dev, undo)
+Called to reschedule polling for device specifically for some
+deficient hardware. Read Appendix 2 for more details.
+
+e) netif_rx_complete(dev)
+
+Remove interface from the CPU poll list: it must be in the poll list
+on current cpu. This primitive is called by dev->poll(), when
+it completes its work. The device cannot be out of poll list at this
+call, if it is then clearly it is a BUG(). You'll know ;->
+
+All these above nethods are used below. So keep reading for clarity.
+
+Device driver changes to be made when porting NAPI
+==================================================
+
+Below we describe what kind of changes are required for NAPI to work.
+
+1) introduction of dev->poll() method 
+=====================================
+
+This is the method that is invoked by the network core when it requests
+for new packets from the driver. A driver is allowed to send upto
+dev->quota packets by the current CPU before yielding to the network
+subsystem (so other devices can also get opportunity to send to the stack).
+
+dev->poll() prototype looks as follows:
+int my_poll(struct net_device *dev, int *budget)
+
+budget is the remaining number of packets the network subsystem on the
+current CPU can send up the stack before yielding to other system tasks.
+*Each driver is responsible for decrementing budget by the total number of
+packets sent.
+	Total number of packets cannot exceed dev->quota.
+
+dev->poll() method is invoked by the top layer, the driver just sends if it 
+can to the stack the packet quantity requested.
+
+more on dev->poll() below after the interrupt changes are explained.
+
+2) registering dev->poll() method
+===================================
+
+dev->poll should be set in the dev->probe() method. 
+e.g:
+dev->open = my_open;
+.
+.
+/* two new additions */
+/* first register my poll method */
+dev->poll = my_poll;
+/* next register my weight/quanta; can be overriden in /proc */
+dev->weight = 16;
+.
+.
+dev->stop = my_close;
+
+
+
+3) scheduling dev->poll()
+=============================
+This involves modifying the interrupt handler and the code
+path which takes the packet off the NIC and sends them to the 
+stack.
+
+it's important at this point to introduce the classical D Becker 
+interrupt processor:
+
+------------------
+static void
+netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
+{
+
+	struct net_device *dev = (struct net_device *)dev_instance;
+	struct my_private *tp = (struct my_private *)dev->priv;
+
+	int work_count = my_work_count;
+        status = read_interrupt_status_reg();
+        if (status == 0)
+                return;         /* Shared IRQ: not us */
+        if (status == 0xffff)
+                return;         /* Hot unplug */
+        if (status & error)
+		do_some_error_handling()
+        
+	do {
+		acknowledge_ints_ASAP();
+
+		if (status & link_interrupt) {
+			spin_lock(&tp->link_lock);
+			do_some_link_stat_stuff();
+			spin_unlock(&tp->link_lock);
+		}
+		
+		if (status & rx_interrupt) {
+			receive_packets(dev);
+		}
+
+		if (status & rx_nobufs) {
+			make_rx_buffs_avail();
+		}
+			
+		if (status & tx_related) {
+			spin_lock(&tp->lock);
+			tx_ring_free(dev);
+			if (tx_died)
+				restart_tx();
+			spin_unlock(&tp->lock);
+		}
+
+		status = read_interrupt_status_reg();
+
+	} while (!(status & error) || more_work_to_be_done);
+
+}
+
+----------------------------------------------------------------------
+
+We now change this to what is shown below to NAPI-enable it:
+
+----------------------------------------------------------------------
+static void
+netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
+{
+	struct net_device *dev = (struct net_device *)dev_instance;
+	struct my_private *tp = (struct my_private *)dev->priv;
+
+        status = read_interrupt_status_reg();
+        if (status == 0)
+                return;         /* Shared IRQ: not us */
+        if (status == 0xffff)
+                return;         /* Hot unplug */
+        if (status & error)
+		do_some_error_handling();
+        
+	do {
+/************************ start note *********************************/		
+		acknowledge_ints_ASAP();  // dont ack rx and rxnobuff here
+/************************ end note *********************************/		
+
+		if (status & link_interrupt) {
+			spin_lock(&tp->link_lock);
+			do_some_link_stat_stuff();
+			spin_unlock(&tp->link_lock);
+		}
+/************************ start note *********************************/		
+		if (status & rx_interrupt || (status & rx_nobuffs)) {
+			if (netif_rx_schedule_prep(dev)) {
+
+				/* disable interrupts caused 
+			         *	by arriving packets */
+				disable_rx_and_rxnobuff_ints();
+				/* tell system we have work to be done. */
+				__netif_rx_schedule(dev);
+			} else {
+				printk("driver bug! interrupt while in poll\n");
+				/* FIX by disabling interrupts  */
+				disable_rx_and_rxnobuff_ints();
+			}
+		}
+/************************ end note note *********************************/		
+			
+		if (status & tx_related) {
+			spin_lock(&tp->lock);
+			tx_ring_free(dev);
+
+			if (tx_died)
+				restart_tx();
+			spin_unlock(&tp->lock);
+		}
+
+		status = read_interrupt_status_reg();
+
+/************************ start note *********************************/		
+	} while (!(status & error) || more_work_to_be_done(status));
+/************************ end note note *********************************/		
+
+}
+
+---------------------------------------------------------------------
+
+
+We note several things from above:
+
+I) Any interrupt source which is caused by arriving packets is now
+turned off when it occurs. Depending on the hardware, there could be
+several reasons that arriving packets would cause interrupts; these are the
+interrupt sources we wish to avoid. The two common ones are a) a packet 
+arriving (rxint) b) a packet arriving and finding no DMA buffers available
+(rxnobuff) .
+This means also acknowledge_ints_ASAP() will not clear the status
+register for those two items above; clearing is done in the place where 
+proper work is done within NAPI; at the poll() and refill_rx_ring() 
+discussed further below.
+netif_rx_schedule_prep() returns 1 if device is in running state and
+gets successfully added to the core poll list. If we get a zero value
+we can _almost_ assume are already added to the list (instead of not running. 
+Logic based on the fact that you shouldnt get interrupt if not running)
+We rectify this by disabling rx and rxnobuf interrupts.
+
+II) that receive_packets(dev) and make_rx_buffs_avail() may have dissapeared.
+These functionalities are still around actually......
+
+infact, receive_packets(dev) is very close to my_poll() and 
+make_rx_buffs_avail() is invoked from my_poll()
+
+4) converting receive_packets() to dev->poll()
+===============================================
+
+We need to convert the classical D Becker receive_packets(dev) to my_poll()
+
+First the typical receive_packets() below:
+-------------------------------------------------------------------
+
+/* this is called by interrupt handler */
+static void receive_packets (struct net_device *dev)
+{
+
+	struct my_private *tp = (struct my_private *)dev->priv;
+	rx_ring = tp->rx_ring;
+	cur_rx = tp->cur_rx;
+	int entry = cur_rx % RX_RING_SIZE;
+	int received = 0;
+	int rx_work_limit = tp->dirty_rx + RX_RING_SIZE - tp->cur_rx;
+
+	while (rx_ring_not_empty) {
+		u32 rx_status;
+		unsigned int rx_size;
+		unsigned int pkt_size;
+		struct sk_buff *skb;
+                /* read size+status of next frame from DMA ring buffer */
+		/* the number 16 and 4 are just examples */
+                rx_status = le32_to_cpu (*(u32 *) (rx_ring + ring_offset));
+                rx_size = rx_status >> 16;
+                pkt_size = rx_size - 4;
+
+		/* process errors */
+                if ((rx_size > (MAX_ETH_FRAME_SIZE+4)) ||
+                    (!(rx_status & RxStatusOK))) {
+                        netdrv_rx_err (rx_status, dev, tp, ioaddr);
+                        return;
+                }
+
+                if (--rx_work_limit < 0)
+                        break;
+
+		/* grab a skb */
+                skb = dev_alloc_skb (pkt_size + 2);
+                if (skb) {
+			.
+			.
+			netif_rx (skb);
+			.
+			.
+                } else {  /* OOM */
+			/*seems very driver specific ... some just pass
+			whatever is on the ring already. */
+                }
+
+		/* move to the next skb on the ring */
+		entry = (++tp->cur_rx) % RX_RING_SIZE;
+		received++ ;
+
+        }
+
+	/* store current ring pointer state */
+        tp->cur_rx = cur_rx;
+
+        /* Refill the Rx ring buffers if they are needed */
+	refill_rx_ring();
+	.
+	.
+
+}
+-------------------------------------------------------------------
+We change it to a new one below; note the additional parameter in
+the call.
+
+-------------------------------------------------------------------
+
+/* this is called by the network core */
+static void my_poll (struct net_device *dev, int *budget)
+{

+-------------------------------------------------------------------
+
+From above we note that:
+0) rx_work_limit = dev->quota 
+1) refill_rx_ring() is in charge of clearing the bit for rxnobuff when
+it does the work.
+2) We have a done and not_done state.
+3) instead of netif_rx() we call netif_receive_skb() to pass the skb.
+4) we have a new way of handling oom condition
+5) A new outer for (;;) loop has been added. This serves the purpose of
+ensuring that if a new packet has come in, after we are all set and done,
+and we have not exceeded our quota that we continue sending packets up.
+ 
+
+-----------------------------------------------------------
+Poll timer code will need to do the following:
+
+a) 
+
+        if (tp->cur_rx - tp->dirty_rx > RX_RING_SIZE/2 ||
+            tp->rx_buffers[tp->dirty_rx % RX_RING_SIZE].skb == NULL)

+	   Restart the timer again. Else we re-add ourselves 
+           to the master poll list.
+         */
+
+        if (tp->rx_buffers[tp->dirty_rx % RX_RING_SIZE].skb == NULL)
+                restart_timer();
+
+	else netif_rx_schedule(dev);  /* we are back on the poll list */
+	
+5) dev->close() and dev->suspend() issues
+==========================================
+The driver writter neednt worry about this. The top net layer takes
+care of it.
+
+6) Adding new Stats to /proc 
+=============================
+In order to debug some of the new features, we introduce new stats
+that need to be collected.
+TODO: Fill this later.
+
+APPENDIX 1: discussion on using ethernet HW FC
+==============================================
+Most chips with FC only send a pause packet when they run out of Rx buffers.
+Since packets are pulled off the DMA ring by a softirq in NAPI,
+if the system is slow in grabbing them and we have a high input
+rate (faster than the system's capacity to remove packets), then theoretically
+there will only be one rx interrupt for all packets during a given packetstorm.
+Under low load, we might have a single interrupt per packet.
+FC should be programmed to apply in the case when the system cant pull out
+packets fast enough i.e send a pause only when you run out of rx buffers.
+Note FC in itself is a good solution but we have found it to not be
+much of a commodity feature (both in NICs and switches) and hence falls
+under the same category as using NIC based mitigation. Also experiments
+indicate that its much harder to resolve the resource allocation
+issue (aka lazy receiving that NAPI offers) and hence quantify its usefullness
+proved harder. In any case, FC works even better with NAPI but is not
+necessary.
+
+
+APPENDIX 2: the "rotting packet" race-window avoidance scheme 
+=============================================================
+
+There are two types of associations seen here
+
+1) status/int which honors level triggered IRQ
+
+If a status bit for receive or rxnobuff is set and the corresponding 
+interrupt-enable bit is not on, then no interrupts will be generated. However, 
+as soon as the "interrupt-enable" bit is unmasked, an immediate interrupt is 
+generated.  [assuming the status bit was not turned off].
+Generally the concept of level triggered IRQs in association with a status and
+interrupt-enable CSR register set is used to avoid the race.
+
+If we take the example of the tulip:
+"pending work" is indicated by the status bit(CSR5 in tulip).
+the corresponding interrupt bit (CSR7 in tulip) might be turned off (but
+the CSR5 will continue to be turned on with new packet arrivals even if
+we clear it the first time)
+Very important is the fact that if we turn on the interrupt bit on when
+status is set that an immediate irq is triggered.
+ 
+If we cleared the rx ring and proclaimed there was "no more work
+to be done" and then went on to do a few other things;  then when we enable
+interrupts, there is a possibility that a new packet might sneak in during
+this phase. It helps to look at the pseudo code for the tulip poll
+routine:
+
+--------------------------
+        do {
+                ACK;
+                while (ring_is_not_empty()) {
+                        work-work-work
+                        if quota is exceeded: exit, no touching irq status/mask
+                }
+                /* No packets, but new can arrive while we are doing this*/
+                CSR5 := read
+                if (CSR5 is not set) {
+                        /* If something arrives in this narrow window here,
+                        *  where the comments are ;-> irq will be generated */
+                        unmask irqs;
+                        exit poll;
+                }
+        } while (rx_status_is_set);
+------------------------
+
+CSR5 bit of interest is only the rx status. 
+If you look at the last if statement: 
+you just finished grabbing all the packets from the rx ring .. you check if
+status bit says theres more packets just in ... it says none; you then
+enable rx interrupts again; if a new packet just came in during this check,
+we are counting that CSR5 will be set in that small window of opportunity
+and that by re-enabling interrupts, we would actually triger an interrupt
+to register the new packet for processing.
+
+[The above description nay be very verbose, if you have better wording 
+that will make this more understandable, please suggest it.]
+
+2) non-capable hardware
+
+These do not generally respect level triggered IRQs. Normally,
+irqs may be lost while being masked and the only way to leave poll is to do
+a double check for new input after netif_rx_complete() is invoked
+and re-enable polling (after seeing this new input).
+
+Sample code:
+
+---------
+	.
+	.
+restart_poll:
+	while (ring_is_not_empty()) {
+		work-work-work
+		if quota is exceeded: exit, not touching irq status/mask
+	}
+	.
+	.
+	.
+	enable_rx_interrupts()
+	netif_rx_complete(dev);
+	if (ring_has_new_packet() && netif_rx_reschedule(dev, received)) {
+		disable_rx_and_rxnobufs()
+		goto restart_poll
+	} while (rx_status_is_set);
+---------
+		
+Basically netif_rx_complete() removes us from the poll list, but because a
+new packet which will never be caught due to the possibility of a race
+might come in, we attempt to re-add ourselves to the poll list.

+To verify that your adapter is supported, find the board ID number on the 
+adapter. Look for a label that has a barcode and a number in the format 
+A12345-001. Match this to the list of numbers above.
+
+For more information on how to identify your adapter, go to the Adapter & 
+Driver ID Guide at:
+
+  http://support.intel.com/support/network/adapter/pro100/21397.htm
+
+For the latest Intel PRO/100 network driver for Linux, see:
+
+  http://downloadfinder.intel.com/scripts-df/support_intel.asp
+
+
+Command Line Parameters
+=======================
+
+The following optional parameters are used by entering them on the command 
+line with the modprobe or insmod command using this syntax:
+
+     modprobe e100 [<option>=<VAL1>,<VAL2>,...]
+
+     insmod e100 [<option>=<VAL1>,<VAL2>,...] 
+
+For example, with two Intel PRO/100 PCI adapters, entering:
+	
+     modprobe e100 TxDescriptors=32,128
+
+loads the e100 driver with 32 TX resources for the first adapter and 128 TX 
+resources for the second adapter. This configuration favors the second 
+adapter. The driver supports up to 16 network adapters concurrently.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTE: Giving any command line option the value "-1" causes the driver to use 
+      the appropriate default value for that option, as if no value was 
+      specified.
+
+
+BundleMax
+Valid Range: 1-65535
+Default Value: 6
+   This parameter holds the maximum number of small packets (less than 128
+   bytes) in a bundle. Suggested values range from 2 to 10. See "CPU Cycle 
+   Saver."
+
+BundleSmallFr
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0
+   The value 1 (on) causes small packets (less than 128 bytes) to be bundled. 
+   See "CPU Cycle Saver."
+
+e100_speed_duplex
+Valid Range: 0-4 (1=10half;2=10full;3=100half;4=100full)
+Default Value: 0
+   The default value of 0 sets the adapter to auto-negotiate. Other values
+   set the adapter to forced speed and duplex. 
+   Example usage: insmod e100.o e100_speed_duplex=4,4 (for two adapters)
+
+flow_control
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0
+   This parameter controls the automatic generation(Tx) and response(Rx) to 
+   Ethernet PAUSE frames. flow_control should NOT be set to 1 when the 
+   adapter is connected to an interface that does not support Ethernet PAUSE 
+   frames and when the e100_speed_duplex parameter is NOT set to zero. 
+
+IntDelay
+Valid Range: 0-65535 (0=off)
+Default Value: 1536
+   This parameter holds the number of time units (in adapter terminology)
+   until the adapter generates an interrupt. The recommended value for 
+   IntDelay is 1536 (upon initialization). Suggested values range from 
+   512 to 2048. See "CPU Cycle Saver."
+
+IFS
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 1
+  Inter Frame Spacing (IFS) aims to reduce the number of Ethernet frame
+  collisions by altering the time between frame transmissions. When IFS is 
+  enabled the driver tries to find an optimal IFS value. It is used only at 
+  half duplex.
+
+RxDescriptors
+Valid Range: 8-1024
+Default Value: 64
+   This parameter defines the number of receive descriptors allocated by 
+   the driver. Increasing this value allows the driver to buffer more 
+   incoming packets before the driver is required to service an interrupt. 
+   The maximum value for Itanium-based systems is 64.
+
+TxDescriptors
+Valid Range: 19-1024
+Default Value: 64
+   This value is the number of transmit descriptors allocated by the driver. 
+   Increasing this value allows the protocol stack to queue more transmits at
+   the driver level. The maximum value for Itanium-based systems is 64.
+
+ucode
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 0 for 82558-based adapters
+               1 for 82559, 82550, and 82551-based adapters
+   On uploads the micro code to the adapter, which enables CPU Cycle Saver. 
+   See the section "CPU Cycle Saver" below.
+   Example usage: insmod e100.o ucode=1
+
+   Not available on 82557-based adapters.
+
+XsumRX
+Valid Range: 0-1 (0=off, 1=on)
+Default Value: 1
+   On allows Rx checksum offloading for TCP/UDP packets. Requires that the 
+   hardware support this feature.
+
+   Not available on 82557 and 82558-based adapters.
+
+
+CPU Cycle Saver
+================
+
+CPU Cycle Saver reduces CPU utilization by reducing the number of interrupts 
+that the adapter generates.
+
+When CPU Cycle Saver is turned off, the adapter generates one interrupt for 
+every frame that is received. This means that the operating system stops what
+it is doing and switches to the network driver in order to process the 
+receive.
+
+When CPU Cycle Saver is on, the adapter does not generate an interrupt for 
+every frame it receives. Instead, it waits until it receives several frames 
+before generating an interrupt. This reduces the amount of time spent 
+switching to and from the driver. 
+
+CPU Cycle Saver consists of these arguments: IntDelay, BundleMax and 
+BundleSmallFr. When IntDelay is increased, the adapter waits longer for 
+frames to arrive before generating the interrupt. By increasing BundleMax, 
+the network adapter waits for the number of small frames (less than 128 bytes)
+specified to arrive before generating the interrupt. When BundleSmallFr is 
+disabled, the adapter does not bundle small packets. Such small packets are 
+often, but not always, control packets that are better served immediately;
+therefore, BundleSmallFr is disabled by default.
+
+For most users, it is recommended that CPU Cycle Saver be used with the 
+default values specified in the Command Line Parameters section. However, in 
+some cases, performance problems may occur with CPU Cycle Saver. If such 
+problems are observed, we recommend turning off this feature by setting 
+ucode=0.

+123456-001 (six digits hyphen three digits). Match this to the list of
+numbers above.
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:

+    http://support.intel.com/support/network/adapter/pro100/21397.htm
+
+For the latest Intel network drivers for Linux, go to:
+
+    http://appsr.intel.com/scripts-df/support_intel.asp
+
+
+Command Line Parameters
+=======================
+
+If the driver is built as a module, the following optional parameters are 
+used by entering them on the command line with the modprobe or insmod command. 
+For example, with two PRO/1000 PCI adapters, entering:
+
+    insmod e1000 TxDescriptors=80,128
+
+loads the e1000 driver with 80 TX resources for the first adapter and 128 TX
+resources for the second adapter.
+
+For more information about the AutoNeg, Duplex, and Speed parameters, see the
+"Speed and Duplex Configuration" section in this document.
+
+
+AutoNeg (adapters using copper connections only)
+Valid Range: 0x01-0x0F, 0x20-0x2F
+Default Value: 0x2F
+    This parameter is a bit mask that specifies which speed and duplex
+    settings the board advertises. When this parameter is used, the Speed and
+    Duplex parameters must not be specified.  
+
+Duplex (adapters using copper connections only)
+Valid Range: 0-2 (0=auto-negotiate, 1=half, 2=full)
+Default Value: 0
+    Defines the direction in which data is allowed to flow. Can by either one 
+    or two-directional. If both Duplex and the link partner are set to auto-
+    negotiate, the board auto-detects the correct duplex. If the link partner
+    is forced (either full or half), Duplex defaults to half-duplex.
+
+FlowControl
+Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+Default: Read flow control settings from the EEPROM
+    This parameter controls the automatic generation(Tx) and response(Rx) to 
+    Ethernet PAUSE frames.
+
+RxDescriptors
+Valid Range: 80-256 for 82542 and 82543-based adapters
+             80-4096 for 82540, 82544, 82545, and 82546-based adapters
+Default Value: 80
+    This value is the number of receive descriptors allocated by the driver. 
+    Increasing this value allows the driver to buffer more incoming packets. 
+    Each descriptor is 16 bytes.  A receive buffer is also allocated for each
+    descriptor and can be either 2048, 4096, 8192, or 16384 bytes, depending 
+    on the MTU setting. The maximum MTU size is 16110.
+
+    NOTE: MTU designates the frame size. It only needs to be set for Jumbo 
+          Frames.
+
+RxIntDelay
+Valid Range: 0-65535 (0=off)
+Default Value: 0
+    This value delays the generation of receive interrupts in units of 1.024 
+    microseconds.  Receive interrupt reduction can improve CPU efficiency if 
+    properly tuned for specific network traffic. Increasing this value adds 
+    extra latency to frame reception and can end up decreasing the throughput 
+    of TCP traffic. If the system is reporting dropped receives, this value 
+    may be set too high, causing the driver to run out of available receive 
+    descriptors.
+
+    CAUTION: When setting RxIntDelay to a value other than 0, adapters may 
+             hang (stop transmitting) under certain network conditions. If
+             this occurs a NETDEV WATCHDOG message is logged in the system
+             event log. In addition, the controller is automatically reset,
+             restoring the network connection. To eliminate the potential for
+             the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay (82540, 82545, and 82546-based adapters only)
+Valid Range: 0-65535 (0=off)
+Default Value: 128
+    This value, in units of 1.024 microseconds, limits the delay in which a 
+    transmit interrupt is generated. Useful only if RxIntDelay is non-zero, 
+    this value ensures that an interrupt is generated after the initial 
+    packet is received within the set amount of time.  Proper tuning,
+    along with RxIntDelay, may improve traffic throughput in specific network
+    conditions.
+
+Speed (adapters using copper connections only)
+Valid Settings: 0, 10, 100, 1000
+Default Value: 0 (auto-negotiate at all supported speeds)
+    Speed forces the line speed to the specified value in megabits per second
+    (Mbps). If this parameter is not specified or is set to 0 and the link 
+    partner is set to auto-negotiate, the board will auto-detect the correct 
+    speed. Duplex must also be set when Speed is set to either 10 or 100.
+
+TxDescriptors
+Valid Range: 80-256 for 82542 and 82543-based adapters
+             80-4096 for 82540, 82544, 82545, and 82546-based adapters
+Default Value: 256
+    This value is the number of transmit descriptors allocated by the driver.
+    Increasing this value allows the driver to queue more transmits. Each 
+    descriptor is 16 bytes.
+
+TxIntDelay
+Valid Range: 0-65535 (0=off)
+Default Value: 64
+    This value delays the generation of transmit interrupts in units of 
+    1.024 microseconds.  Transmit interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic. If the
+    system is reporting dropped transmits, this value may be set too high
+    causing the driver to run out of available transmit descriptors.
+
+TxAbsIntDelay (82540, 82545, and 82546-based adapters only)
+Valid Range: 0-65535 (0=off)
+Default Value: 64
+    This value, in units of 1.024 microseconds, limits the delay in which a 
+    transmit interrupt is generated. Useful only if TxIntDelay is non-zero, 
+    this value ensures that an interrupt is generated after the initial 
+    packet is sent on the wire within the set amount of time.  Proper tuning,
+    along with TxIntDelay, may improve traffic throughput in specific 
+    network conditions.
+
+XsumRX (not available on the PRO/1000 Gigabit Server Adapter)
+Valid Range: 0-1
+Default Value: 1
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for received packets (both UDP and TCP) to the adapter hardware.
+
+
+Speed and Duplex Configuration
+==============================
+
+Three keywords are used to control the speed and duplex configuration. These
+keywords are Speed, Duplex, and AutoNeg.
+
+If the board uses a fiber interface, these keywords are ignored, and the
+fiber interface board only links at 1000 Mbps full-duplex.
+
+For copper-based boards, the keywords interact as follows:
+
+  The default operation is auto-negotiate. The board advertises all supported
+  speed and duplex combinations, and it links at the highest common speed and
+  duplex mode IF the link partner is set to auto-negotiate.
+
+  If Speed = 1000, limited auto-negotiation is enabled and only 1000 Mbps is
+  advertised (The 1000BaseT spec requires auto-negotiation.)
+
+  If Speed = 10 or 100, then both Speed and Duplex must be set. Auto-
+  negotiation is disabled, and the AutoNeg parameter is ignored. Partner MUST
+  also be forced.
+
+The AutoNeg parameter is used when more control is required over the auto-
+negotiation process.  When this parameter is used, Speed and Duplex must not
+be specified.  This parameter is a bitmap that specifies which speed and
+duplex settings are advertised to the link partner.
+
+Bit            7      6      5       4       3      2      1       0
+Speed (Mbps)   N/A    N/A    1000    N/A     100    100    10      10
+Duplex                       Full            Full   Half   Full    Half
+
+Note that setting AutoNeg does not guarantee that the board will link at the
+highest specified speed or duplex mode, but the board will link at the
+highest possible speed/duplex of the link partner IF the link partner is also
+set to auto-negotiate. If the link partner is forced speed/duplex, the
+adapter MUST be forced to the same speed/duplex.
+
+
+Additional Configurations
+=========================
+
+  Jumbo Frames
+  ------------
+
+  The driver supports Jumbo Frames for all adapters except 82542-based
+  adapters.  Jumbo Frames support is enabled by changing the MTU to a value
+  larger than the default of 1500.  Use the ifconfig command to increase the
+  MTU size. For example:
+
+        ifconfig ethx mtu 9000 up
+
+
+Known Issues
+============
+
+  Jumbo Frames System Requirement
+  -------------------------------
+
+  Memory allocation failures have been observed on Linux systems with 64 MB
+  of RAM or less that are running Jumbo Frames. If you are using Jumbo
+  Frames, your system may require more than the advertised minimum
+  requirement of 64 MB of system memory.

+  instead of receiving packets from physical media, receives them from 
   user space program and instead of sending packets via physical media 
   writes them to the user space program. 
 
-  When a program opens /dev/net/tun, driver creates and registers corresponding
-  net device tunX or tapX. After a program closed above devices, driver will 
-  automatically delete tunXX or tapXX device and all routes corresponding to it.
-
-  This package(http://vtun.sourceforge.net/tun) contains two simple example 
-  programs how to use tun and tap devices. Both programs works like 
-  bridge between two network interfaces.
+  In order to use the driver a program has to open /dev/net/tun and issue a
+  corresponding ioctl() to register a network device with the kernel. A network
+  device will appear as tunXX or tapXX, depending on the options chosen. When
+  the program closes the file descriptor, the network device and all
+  corresponding routes will disappear.
+
+  Depending on the type of device chosen the userspace program has to read/write
+  IP packets (with tun) or ethernet frames (with tap). Which one is being used
+  depends on the flags given with the ioctl().
+
+  The package from http://vtun.sourceforge.net/tun contains two simple examples
+  for how to use tun and tap devices. Both programs work like a bridge between

 Universal TUN/TAP device driver Frequently Asked Question.
    
-1. What is the TUN ?
-The TUN is Virtual Point-to-Point network device.
-TUN driver was designed as low level kernel support for
-IP tunneling. It provides to userland application
-two interfaces:
-  - /dev/tunX	- character device;
-  - tunX	- virtual Point-to-Point interface.
-
-Userland application can write IP frame to /dev/tunX
-and kernel will receive this frame from tunX interface. 
-In the same time every frame that kernel writes to tunX 
-interface can be read by userland application from /dev/tunX
-device.
-
-2. What is the TAP ?
-The TAP is a Virtual Ethernet network device.
-TAP driver was designed as low level kernel support for
-Ethernet tunneling. It provides to userland application
-two interfaces:
-  - /dev/tapX	- character device;
-  - tapX	- virtual Ethernet interface.
-
-Userland application can write Ethernet frame to /dev/tapX
-and kernel will receive this frame from tapX interface. 
-In the same time every frame that kernel writes to tapX 
-interface can be read by userland application from /dev/tapX

+1. What platforms are supported by TUN/TAP driver ?
 Currently driver has been written for 3 Unices:
    Linux kernels 2.2.x, 2.4.x 
    FreeBSD 3.x, 4.x, 5.x
    Solaris 2.6, 7.0, 8.0

+2. What is TUN/TAP driver used for?
 As mentioned above, main purpose of TUN/TAP driver is tunneling. 
 It is used by VTun (http://vtun.sourceforge.net).
 
-5. How does Virtual network device actually work ? 
+Another interesting application using TUN/TAP is pipsecd
+(http://perso.enst.fr/~beyssac/pipsec/), an userspace IPSec
+implementation that can use complete kernel routing (unlike FreeS/WAN).
+
+3. How does Virtual network device actually work ? 
 Virtual network device can be viewed as a simple Point-to-Point or
 Ethernet device, which instead of receiving packets from a physical 
 media, receives them from user space program and instead of sending 
 packets via physical media sends them to the user space program. 
 
 Let's say that you configured IPX on the tap0, then whenever 
-kernel sends any IPX packet to tap0, it is passed to the application
-(VTun for example). Application encrypts, compresses and sends it to 
-the other side over TCP or UDP. Application on other side decompress 
-and decrypts them and write packet to the TAP device, kernel handles 
-the packet like it came from real physical device.

+Hollis Blanchard <hollis@austin.ibm.com>
+5 Jun 2002
+
+This document describes the system (including self-modifying code) used in the
+PPC Linux kernel to support a variety of PowerPC CPUs without requiring
+compile-time selection.
+
+Early in the boot process the ppc32 kernel detects the current CPU type and
+chooses a set of features accordingly. Some examples include Altivec support,
+split instruction and data caches, and if the CPU supports the DOZE and NAP
+sleep modes.
+
+Detection of the feature set is simple. A list of processors can be found in
+arch/ppc/kernel/cputable.c. The PVR register is masked and compared with each
+value in the list. If a match is found, the cpu_features of cur_cpu_spec is
+assigned to the feature bitmask for this processor and a __setup_cpu function
+is called.
+
+C code may test 'cur_cpu_spec[smp_processor_id()]->cpu_features' for a
+particular feature bit. This is done in quite a few places, for example
+in ppc_setup_l2cr().
+
+Implementing cpufeatures in assembly is a little more involved. There are
+several paths that are performance-critical and would suffer if an array
+index, structure dereference, and conditional branch were added. To avoid the
+performance penalty but still allow for runtime (rather than compile-time) CPU
+selection, unused code is replaced by 'nop' instructions. This nop'ing is
+based on CPU 0's capabilities, so a multi-processor system with non-identical
+processors will not work (but such a system would likely have other problems
+anyways).
+
+After detecting the processor type, the kernel patches out sections of code
+that shouldn't be used by writing nop's over it. Using cpufeatures requires
+just 2 macros (found in include/asm-ppc/cputable.h), as seen in head.S
+transfer_to_handler:
+
+	#ifdef CONFIG_ALTIVEC
+	BEGIN_FTR_SECTION
+		mfspr	r22,SPRN_VRSAVE		/* if G4, save vrsave register value */
+		stw	r22,THREAD_VRSAVE(r23)
+	END_FTR_SECTION_IFSET(CPU_FTR_ALTIVEC)
+	#endif /* CONFIG_ALTIVEC */
+
+If CPU 0 supports Altivec, the code is left untouched. If it doesn't, both
+instructions are replaced with nop's.
+
+The END_FTR_SECTION macro has two simpler variations: END_FTR_SECTION_IFSET
+and END_FTR_SECTION_IFCLR. These simply test if a flag is set (in
+cur_cpu_spec[0]->cpu_features) or is cleared, respectively. These two macros
+should be used in the majority of cases.
+
+The END_FTR_SECTION macros are implemented by storing information about this
+code in the '__ftr_fixup' ELF section. When do_cpu_ftr_fixups
+(arch/ppc/kernel/misc.S) is invoked, it will iterate over the records in
+__ftr_fixup, and if the required feature is not present it will loop writing
+nop's from each BEGIN_FTR_SECTION to END_FTR_SECTION.

 ChangeLog for the UTS Global 3270-support patch
 
+Sep 2002:	Get bootup colors right on 3270 console
+	* In tubttybld.c, substantially revise ESC processing so that
+	  ESC sequences (especially coloring ones) and the strings
+	  they affect work as right as 3270 can get them.  Also, set
+	  screen height to omit the two rows used for input area, in
+	  tty3270_open() in tubtty.c.
+
+Sep 2002:	Dynamically get 3270 input buffer
+	* Oversize 3270 screen widths may exceed GEOM_MAXINPLEN columns,
+	  so get input-area buffer dynamically when sizing the device in
+	  tubmakemin() in tuball.c (if it's the console) or tty3270_open()
+	  in tubtty.c (if needed).  Change tubp->tty_input to be a
+	  pointer rather than an array, in tubio.h.
+
+Sep 2002:	Fix tubfs kmalloc()s
+	* Do read and write lengths correctly in fs3270_read()
+	  and fs3270_write(), whilst never asking kmalloc()
+	  for more than 0x800 bytes.  Affects tubfs.c and tubio.h.
+
+Sep 2002:	Recognize 3270 control unit type 3174
+	* Recognize control-unit type 0x3174 as well as 0x327?.
+	  The IBM 2047 device emulates a 3174 control unit.
+	  Modularize control-unit recognition in tuball.c by
+	  adding and invoking new tub3270_is_ours().
+
+Apr 2002:	Fix 3270 console reboot loop
+	* (Belated log entry) Fixed reboot loop if 3270 console,
+	  in tubtty.c:ttu3270_bh().
+
 Feb 6, 2001:
 	* This changelog is new
 	* tub3270 now supports 3270 console:

+     forte - an OSS/Lite driver for FortéMedia FM801 sound chips
+     ===========================================================
+
+This is a driver for cards using the FortéMedia FM801 audio
+controller.  The Genius Sound Maker Live card and the onboard audio in
+HP Workstation zx2000 has been tested.
+
+Both IA-32 and IA-64 architectures are supported, but the driver
+should work on any platform.
+
+The FM801 controller supports a variety of AC'97 codecs.  This driver
+lets the OSS core code figure the codec out, and should thus support
+any codec with support in the Linux kernel.
+
+The driver supports /dev/mixer and /dev/dsp for generic OSS audio
+support.  In general it adheres to the OSS spec to the extent it can
+be done with the way the hardware works.  The FM801 controller doesn't
+support scatter-gather, so if the application sets fragment size too
+low, it puts strict requirements on interrupt processing speed.  The
+driver tries to compensate by enforcing bigger buffers than requested
+by the application if the fragment size is low.
+
+The forte driver includes both standard read()/write() and the
+unsupported mmap() interface used by Quake.  mmap() is only supported
+in playback mode.
+
+U8 and S16 audio formats are supported, mono/stereo, as well as most
+all sample rates implemented by the chip.  Default is 48 KHz, 16-bit,
+mono.
+
+MIDI, FM audio, and the gameport controller are not currently
+supported.
+
+
+The latest version of this driver can be found at:

+Readme for Linux device driver for the Texas Instruments SilverLink cable
+-------------------------------------------------------------------------
+
+Author: Romain Liévin & Julien Blache
+Homepage: http://lpg.ticalc.org/prj_usb
+
+INTRODUCTION:
+
+This is a driver for the TI-GRAPH LINK USB (aka SilverLink) cable, a cable 
+designed by TI for connecting their TI8x/9x calculators to a computer 
+(PC or Mac usually).
+
+If you need more information, please visit the 'SilverLink drivers' homepage 
+at the above URL.
+
+WHAT YOU NEED:
+
+A TI calculator of course and a program capable to communicate with your 
+calculator.
+TiLP will work for sure (since I am his developer !). yal92 may be able to use
+it by changing tidev for tiglusb (may require some hacking...).
+
+HOW TO USE IT:
+
+You must have first compiled USB support, support for your specific USB host
+controller (UHCI or OHCI).
+
+Next, (as root) from your appropriate modules directory (lib/modules/2.5.XX):
+
+       insmod usb/usbcore.o
+       insmod usb/usb-uhci.o  <OR>  insmod usb/ohci-hcd.o
+       insmod tiglusb.o
+
+If it is not already there (it usually is), create the device:
+
+       mknod /dev/tiglusb0 c 115 16
+
+You will have to set permissions on this device to allow you to read/write
+from it:
+
+       chmod 666 /dev/tiglusb0
+       
+Now you are ready to run a linking program such as TiLP. Be sure to configure 
+it properly (RTFM).
+       
+MODULE PARAMETERS:
+
+  You can set these with:  insmod tiglusb NAME=VALUE
+  There is currently no way to set these on a per-cable basis.
+
+  NAME: timeout
+  TYPE: integer
+  DEFAULT: 15
+  DESC: Timeout value in tenth of seconds. If no data is available once this 
+       time has expired then the driver will return with a timeout error.
+
+QUIRKS:
+
+The following problem seems to be specific to the link cable since it appears 
+on all platforms (Linux, Windows, Mac OS-X). 
+
+In some very particular cases, the driver returns with success but
+without any data. The application should retry a read operation at least once.
+
+HOW TO CONTACT US:
+
+You can email me at roms@lpg.ticalc.org. Please prefix the subject line
+with "TIGLUSB: " so that I am certain to notice your message.
+You can also mail JB at jb@jblache.org: he has written the first release of 
+this driver but he better knows the Mac OS-X driver.
+
+CREDITS:
+
+The code is based on dabusb.c, printer.c and scanner.c !
+The driver has been developed independantly of Texas Instruments.

+The paging design used on the x86-64 linux kernel port in 2.4.x provides:
+
+o	per process virtual address space limit of 512 Gigabytes
+o	top of userspace stack located at address 0x0000007fffffffff
+o	PAGE_OFFSET = 0xffff800000000000
+o	start of the kernel mapping =  0x0000010000000000
+o	global RAM per system 508*512GB=254 Terabytes
+o	no need of any common code change
+o       512GB of vmalloc/ioremap space
+
+Description:
+        x86-64 has a 4 level page structure, similar to ia32 PSE but with
+        some extensions. Each level consits of a 4K page with 512 64bit
+        entries. The levels are named in Linux PML4, PGD, PMD, PTE; AMD calls them
+        PML4E, PDPE, PDE, PTE respectively. For direct and kernel mapping
+        only 3 levels are used with the PMD pointing to 2MB pages.
+          
+	Userspace is able to modify and it sees only the 3rd/2nd/1st level
+	pagetables (pgd_offset() implicitly walks the 1st slot of the 4th
+	level pagetable and it returns an entry into the 3rd level pagetable).
+	This is where the per-process 512 Gigabytes limit cames from.
+
+	The common code pgd is the PDPE, the pmd is the PDE, the
+	pte is the PTE. The PML4 remains invisible to the common
+	code.
+
+	Since the per-process limit is 512 Gigabytes (due to kernel common
+	code 3 level pagetable limitation), the higher virtual address mapped
+	into userspace is 0x7fffffffff and it makes sense to use it
+	as the top of the userspace stack to allow the stack to grow as
+	much as possible.
+
+	The kernel mapping and the direct memory mapping are split. Direct memory
+	mapping starts directly after userspace after a 512GB gap, while 
+	kernel mapping is at the end of (negative) virtual address space to exploit 
+	the kernel code model. There is no support for discontig memory, this
+	implies that kernel mapping/vmalloc/ioremap/module mapping are not 
+	represented in their "real" mapping in mem_map, but only with their
+	direct mapped (but normally not used) alias.
+	
+Future:
+
+	During 2.5.x we can break the 512 Gigabytes per-process limit
+	possibly by removing from the common code any knowledge about the
+	architectural dependent physical layout of the virtual to physical
+	mapping.
+
+	Once the 512 Gigabytes limit will be removed the kernel stack will
+	be moved (most probably to virtual address 0x00007fffffffffff).
+	Nothing	will break in userspace due that move, as nothing breaks
+	in IA32 compiling the kernel with CONFIG_2G.
+
+Linus agreed on not breaking common code and to live with the 512 Gigabytes
+per-process limitation for the 2.4.x timeframe and he has given me and Andi
+some very useful hints... (thanks! :)
+
+Thanks also to H. Peter Anvin for his interesting and useful suggestions on
+the x86-64-discuss lists!
+
+Current PML4 Layout:
+	Each CPU has an PML4 page that never changes. 
+	Each slot is 512GB of virtual memory. 
+ 
+        0    user space pgd or 40MB low mapping at bootup.  Changed at context switch.
+        1    unmapped
+        2    __PAGE_OFFSET - start of direct mapping of physical memory
+        ...  direct mapping in further slots as needed.
+        510  vmalloc and ioremap space
+	511  kernel code mapping, fixmaps and modules.  
+
+Other memory management related issues follows:
+
+PAGE_SIZE:
+
+	If somebody is wondering why these days we still have a so small
+	4k pagesize (16 or 32 kbytes would be much better for performance
+	of course), the PAGE_SIZE have to remain 4k for 32bit apps to
+	provide 100% backwards compatible IA32 API (we can't allow silent
+	fs corruption or as best a loss of coherency with the page cache
+	by allocating MAP_SHARED areas in MAP_ANONYMOUS memory with a
+	do_mmap_fake). I think it could be possible to have a dynamic page
+	size between 32bit and 64bit apps but it would need extremely
+	intrusive changes in the common code as first for page cache and
+	we sure don't want to depend on them right now even if the
+	hardware would support that.
+
+PAGETABLE SIZE:
+
+	In turn we can't afford to have pagetables larger than 4k because
+	we could not be able to allocate them due physical memory
+	fragmentation, and failing to allocate the kernel stack is a minor
+	issue compared to failing the allocation of a pagetable. If we
+	fail the allocation of a pagetable the only thing we can do is to
+	sched_yield polling the freelist (deadlock prone) or to segfault
+	the task (not even the sighandler would be sure to run).
+
+KERNEL STACK:
+
+	1st stage:
+
+	The kernel stack will be at first allocated with an order 2 allocation
+	(16k) (the utilization of the stack for a 64bit platform really
+	isn't exactly the double of a 32bit platform because the local
+	variables may not be all 64bit wide, but not much less). This will
+	make things even worse than they are right now on IA32 with
+	respect of failing fork/clone due memory fragmentation.
+
+	2nd stage:
+
+	We'll benchmark if reserving one register as task_struct
+	pointer will improve performance of the kernel (instead of
+	recalculating the task_struct pointer starting from the stack
+	pointer each time). My guess is that recalculating will be faster
+	but it worth a try.
+
+		If reserving one register for the task_struct pointer
+		will be faster we can as well split task_struct and kernel
+		stack. task_struct can be a slab allocation or a
+		PAGE_SIZEd allocation, and the kernel stack can then be
+		allocated in a order 1 allocation. Really this is risky,
+		since 8k on a 64bit platform is going to be less than 7k
+		on a 32bit platform but we could try it out. This would
+		reduce the fragmentation problem of an order of magnitude
+		making it equal to the current IA32.
+
+		We must also consider the x86-64 seems to provide in hardware a
+		per-irq stack that could allow us to remove the irq handler
+		footprint from the regular per-process-stack, so it could allow
+		us to live with a smaller kernel stack compared to the other
+		linux architectures.
+
+	3rd stage:
+
+	Before going into production if we still have the order 2
+	allocation we can add a sysctl that allows the kernel stack to be
+	allocated with vmalloc during memory fragmentation. This have to
+	remain turned off during benchmarks :) but it should be ok in real
+	life.
+
+Order of PAGE_CACHE_SIZE and other allocations:
+
+	On the long run we can increase the PAGE_CACHE_SIZE to be
+	an order 2 allocations and also the slab/buffercache etc.ec..
+	could be all done with order 2 allocations. To make the above
+	to work we should change lots of common code thus it can be done
+	only once the basic port will be in a production state. Having
+	a working PAGE_CACHE_SIZE would be a benefit also for
+	IA32 and other architectures of course.
+
+vmalloc:
+	vmalloc should be outside the first 512GB to keep that space free
+	for the user space. It needs an own pgd to work on in common code. 
+	It currently gets an own pgd in the 510th slot of the per CPU PML4.
+	
+PML4: 
+        Each CPU as an own PML4 (=top level of the 4 level page hierarchy). On 
+        context switch the first slot is rewritten to the pgd of the new process 
+        and CR3 is flushed.
+    
+Modules: 
+	Modules need to be in the same 4GB range as the core kernel. Otherwise
+	a GOT would be needed. Modules are currently at 0xffffffffa0000000
+        to 0xffffffffafffffff. This is inbetween the kernel text and the 
+        vsyscall/fixmap mappings.
+
+Vsyscalls: 
+        Vsyscalls have a reserved space near the end of user space that is 
+        acessible by user space. This address is part of the ABI and cannot be
+        changed. They have ffffffffff600000 to ffffffffffe00000 (but only 
+        some small space at the beginning is allocated and known to user space 
+        currently). See vsyscall.c for more details. 
+
+Fixmaps: 
+        Fixed mappings set up at boot. Used to access IO APIC and some other hardware. 
+        These are at the end of vsyscall space (ffffffffffe00000) downwards, 
+        but are not accessible by user space of course.
+
+Early mapping:
+        On a 120TB memory system bootmem could use upto 3.5GB
+        of memory for its bootmem bitmap. To avoid having to map 3.5GB by hand
+        for bootmem's purposes the full direct mapping is created before bootmem
+        is initialized. The direct mapping needs some memory for its page tables,
+        these are directly taken from the physical memory after the kernel. To
+        access these pages they need to be mapped, this is done by a temporary 
+        mapping with a few spare static 2MB PMD entries.
+
+Unsolved issues: 
+	 2MB pages for user space - may need to add a highmem zone for that again to 
+	 avoid fragmentation.

+ * 	- Update Config.help entry. I got a number of emails asking

+ * 	  piece of code... So: "SRM is something like BIOS for your
+ * 	  Alpha"
+ * 	- Update code formatting a bit to better conform CodingStyle
+ * 	  rules.
+ * 	- So this is v0.0.5, with no changes (except formatting)
+ * 	
  * Wed, 22 May 2002 00:11:21 +0200
  * 	- Fix typo on comment (SRC -> SRM)
  * 	- Call this "Version 0.0.4"

+*! FILE NAME  : vertex.c
+*!
+*! DESCRIPTION: Implements an interface towards virtex FPGA (mounted on one of our
+*!              evaluation boards) from userspace using ioctl()'s
+*!
+*!              The FPGA can be programmed by copying the bit-file to /dev/fpga.
+*!
+*!                cp fpga.bit > /dev/fpga
+*!
+*!                Kernel log should look like:
+*!                  69900 bytes written
+*!                  FPGA-configuration completed, no errors
+*!
+*!              Number of bytes written depends on the FPGA
+*!
+*!                From Xilinx data sheet:
+*!                XCV50    559,200 bits
+*!                XCV100   781,216 bits
+*!                XCV800 4,715,616 bits
+*!
+*!              Accepted file type is the design.bit generated by Alliance
+*!              Design Manager.
+*!              This software just sends the bitfile into the device without
+*!              checking device type etc.
+*!
+*!              Sync-header 0xff 0xff 0xff 0xff defines the start for the
+*!              byte stream, everything from that position is written to the FPGA.
+*!
+*!  
+*! Jul 19 2002  Stefan Lundberg    Initial version.
+*! $Log: virtex.c,v $
+*! Revision 1.1  2002/06/25 09:58:58  stefanl

+ *
+ * Revision 1.3  2000/11/23 10:10:20  johana
+ * More debug/logging possibilities.
+ * Moved GET_JIFFIES_USEC() to timex.h and time.c
+ *
+ * Revision 1.2  2000/11/01 13:41:04  johana
+ * Clean up and bugfixes.
+ * Created new do_gettimeofday_fast() that gets a timeval struct
+ * with time based on jiffies and *R_TIMER0_DATA, uses a table
+ * for fast conversion of timer value to microseconds.
+ * (Much faster the standard do_gettimeofday() and we don't really
+ * wan't to use the true time - we wan't the "uptime" so timers don't screw up
+ * when we change the time.
+ * TODO: Add efficient support for continuous timers as well.
+ *

 /*
  * Here is what the interrupt logic between a PCI device and the CPU looks like:
  *
  * (1) A PCI device raises one of the four interrupt pins (INTA, INTB, INTC, INTD).  The
- *     device is uniquely identified by its bus--, and slot-number (the function
+ *     device is uniquely identified by its segment--, bus--, and slot-number (the function
  *     number does not matter here because all functions share the same interrupt
  *     lines).
  *
  * (2) The motherboard routes the interrupt line to a pin on a IOSAPIC controller.
  *     Multiple interrupt lines may have to share the same IOSAPIC pin (if they're level
- *     triggered and use the same polarity).  Each interrupt line has a unique IOSAPIC
- *     irq number which can be calculated as the sum of the controller's base irq number
- *     and the IOSAPIC pin number to which the line connects.
+ *     triggered and use the same polarity).  Each interrupt line has a unique Global
+ *     System Interrupt (GSI) number which can be calculated as the sum of the controller's
+ *     base GSI number and the IOSAPIC pin number to which the line connects.
  *
- * (3) The IOSAPIC uses an internal table to map the IOSAPIC pin into the IA-64 interrupt
- *     vector.  This interrupt vector is then sent to the CPU.
+ * (3) The IOSAPIC uses internal routing table entries (RTEs) to map the IOSAPIC pin
+ *     to the IA-64 interrupt vector.  This interrupt vector is then sent to the CPU.
  *
- * In other words, there are two levels of indirections involved:
+ * (4) The kernel recognizes an interrupt as an IRQ.  The IRQ interface
+ *     is an architecture-independent interrupt handling mechanism in
+ *     Linux.  An IRQ is a number, so we need a mapping between IRQ
+ *     numbers and IA-64 vectors.  The platform_irq_to_vector(irq) and
+ *     platform_local_vector_to_irq(vector) APIs can define platform-
+ *     specific mappings.
  *
- *	pci pin -> iosapic irq -> IA-64 vector
+ * To sum up, there are three levels of mappings involved:
  *
- * Note: outside this module, IA-64 vectors are called "irqs".  This is because that's
- * the traditional name Linux uses for interrupt vectors.
+ *	PCI pin -> global system interrupt (GSI) -> IA-64 vector <-> IRQ
+ *
+ * Note: The term "IRQ" is loosely used everywhere in the Linux kernel
+ * to describe interrupts.  In this module, "IRQ" refers only to Linux
+ * IRQ numbers ("isa_irq" is an exception to this rule).

+/*
+ * McKinley-optimized version of copy_page().
+ *
+ * Copyright (C) 2002 Hewlett-Packard Co
+ *	David Mosberger <davidm@hpl.hp.com>
+ *
+ * Inputs:
+ *	in0:	address of target page
+ *	in1:	address of source page
+ * Output:
+ *	no return value
+ *
+ * General idea:
+ *	- use regular loads and stores to prefetch data to avoid consuming M-slot just for
+ *	  lfetches => good for in-cache performance
+ *	- avoid l2 bank-conflicts by not storing into the same 16-byte bank within a single
+ *	  cycle
+ *
+ * Principle of operation:
+ *	First, note that L1 has a line-size of 64 bytes and L2 a line-size of 128 bytes.
+ *	To avoid secondary misses in L2, we prefetch both source and destination with a line-size
+ *	of 128 bytes.  When both of these lines are in the L2 and the first half of the
+ *	source line is in L1, we start copying the remaining words.  The second half of the
+ *	source line is prefetched in an earlier iteration, so that by the time we start
+ *	accessing it, it's also present in the L1.
+ *
+ *	We use a software-pipelined loop to control the overall operation.  The pipeline
+ *	has 2*PREFETCH_DIST+K stages.  The first PREFETCH_DIST stages are used for prefetching
+ *	source cache-lines.  The second PREFETCH_DIST stages are used for prefetching destination
+ *	cache-lines, the last K stages are used to copy the cache-line words not copied by
+ *	the prefetches.  The four relevant points in the pipelined are called A, B, C, D:
+ *	p[A] is TRUE if a source-line should be prefetched, p[B] is TRUE if a destination-line
+ *	should be prefetched, p[C] is TRUE if the second half of an L2 line should be brought
+ *	into L1D and p[D] is TRUE if a cacheline needs to be copied.
+ *
+ *	This all sounds very complicated, but thanks to the modulo-scheduled loop support,
+ *	the resulting code is very regular and quite easy to follow (once you get the idea).
+ *
+ *	As a secondary optimization, the first 2*PREFETCH_DIST iterations are implemented
+ *	as the separate .prefetch_loop.  Logically, this loop performs exactly like the
+ *	main-loop (.line_copy), but has all known-to-be-predicated-off instructions removed,
+ *	so that each loop iteration is faster (again, good for cached case).
+ *
+ *	When reading the code, it helps to keep the following picture in mind:
+ *
+ *	       word 0 word 1
+ *            +------+------+---
+ *	      |	v[x] | 	t1  | ^
+ *	      |	t2   |	t3  | |
+ *	      |	t4   |	t5  | |
+ *	      |	t6   |	t7  | | 128 bytes
+ *     	      |	n[y] | 	t9  | |	(L2 cache line)
+ *	      |	t10  | 	t11 | |
+ *	      |	t12  | 	t13 | |
+ *	      |	t14  | 	t15 | v
+ *	      +------+------+---
+ *
+ *	Here, v[x] is copied by the (memory) prefetch.  n[y] is loaded at p[C]
+ *	to fetch the second-half of the L2 cache line into L1, and the tX words are copied in
+ *	an order that avoids bank conflicts.

+ * 2) We need not check against bits in the status register IRQ mask, that

+ *
+ * Furthermore, the IRQs on the INDY look basically (barring software IRQs

+ *	MIPS IRQ	Source
+ *      --------        ------
+ *             0	Software (ignored)
+ *             1        Software (ignored)

+ *             7        R4k timer (what we use)
+ *
+ * We handle the IRQ according to _our_ priority which is:
+ *
+ * Highest ----     R4k Timer
+ *                  Local IRQ zero
+ *                  Local IRQ one

+ *                  8254 Timer zero

- * cp1emu.c: a MIPS c	processor 1 (fpu) instructck_ emulatora- * 
- * A c	mplete emulator for MIPS c	processor 1 instructck_s.  This is
- * required for #float(switch) or #float(trap), whereTit catches all
- * COP1 instructck_s via the "CoProcessor Unusable" exce
+
it.  
- *
- * More surprisingly	it is also required for #float(ieee), to help out
- * the hardware fpu at the boun ariei of the IEEE-754 representatck_
- * (denormalised values, infinities, underflow, etc).  It is made
- * quite	nasty because	emulatck_ of some non-COP1 instructck_s is
- * required, e.g. in branch delay slots.
- * 
- * Notes: 
- *  1) the IEEE754 library (-le) performs the	actual arithmetcc;
- *  2) if you know that you won't have an fpu, then you'll get much 
- *     better	performance by c	mpiling with -msoft-float!
- *
- *  Nov 7, 2cu2C- *  Massive changes to integrate with Ld(;  k {
el.
- *
- *  Replag  use	of k {
el  a+a	area with use	of user stRck	
- *  for executck_ of instructck_s in branch delay slots.
- *
- *  Replag  use	of stRtcc k {
el variables with thread_struct elements.

Otherwise, call get_stack_use_cr31C+	 *          to get a pointer to the base of the interrupt stackC+	 *          and push a pt_regs structure on that stack.C+	 *      elseC+	 *          Need to set up a kernel stack, so call theC+	 *          get_stack_use_cr30 macro to set up a pointerC+	 *          to the pt_regs structure contained within theC+	 *          task pointer pointed to by cr30.

+	 * %r8 (a shadowed register) which temporarily contained
+	 * either the fault type ("code") or the eirr. We need
+	 * to use a non-shadowed register to carry the value over
+	 * the rfir in virt_map. We use %r26 since this value winds
+	 * up being passed as the argument to either do_cpu_irq_mask
+	 * or handle_interruption. %r29 is used to hold a pointerC+	 * the register save area, and once again, it needs to
+	 * be a non-shadowed register so that it survives the rfir.

+	 * N.B. TASK_SZ_ALGN and PT_SZ_ALGN include space for a stack frame.

+ *
+ *	 - the name of the pdc wrapper should match one of the macros
+ *	   used for the first two arguments
+ *	 - don't use caps for random parts of the name
+ *	 - use the static PDC result buffers and "copyout" to structs
+ *	   supplied by the caller to encapsulate alignment restrictions
+ *	 - hold pdc_lock while in PDC or using static result buffers
+ *	 - use __pa() to convert virtual (kernel) pointers to physical
+ *	   ones.
+ *	 - the name of the struct used for pdc return values should equal
+ *	   one of the macros used for the first two arguments to the
+ *	   corresponding PDC call
+ *	 - keep the order of arguments
+ *	 - don't be smart (setting trailing NUL bytes for strings, returnC+ *	   something useful even if the call failed) unless you are sureC+ *	   it's not going to affect functionality or performance
+ *
+ *	Example:
+ *	int pdc_cache_info(struct pdc_cache_info *cache_info )
+ *	{

+ *
+ *		spin_lock_irq(&pdc_lock);
+ *		retval = mem_pdc_call(PDC_CACHE,PDC_CACHE_INFO,__pa(cache_info),0);

+ * NOTE: Code in clear_user_page has a hard coded dependency on the
+ *       maximum alias boundary being 4 Mb. We've been assured by the
+ *       parisc chip designers that there will not ever be a parisc
+ *       chip with a larger alias boundary (Never say never :-) ).
+ *
+ *       Subtle: the dtlb miss handlers support the temp alias region by
+ *       "knowing" that if a dtlb miss happens within the temp alias
+ *       region it must have occurred while in clear_user_page. Since
+ *       this routine makes use of processor local translations, we
+ *       don't want to insert them into the kernel page table. Instead,
+ *       we load up some general registers (they need to be registers
+ *       which aren't shadowed) with the physical page numbers (preshifted
+ *       for tlb insertion) needed to insert the translations. When we
+ *       miss on the translation, the dtlb miss handler inserts the
+ *       translation into the tlb using these values:
+ *
+ *          %r26 physical page (shifted for tlb insert) of "to" translation
+ *          %r23 physical page (shifted for tlb insert) of "from" translation

+	 * makes more sense to just copy through the kernel translation
+	 * and flush it.
+	 *
+	 * I'm still keeping this around because it may be possible to
+	 * use it if more information is passed into copy_user_page().

+/*
+ *  Edited comment from original sources:
+ *
+ *  This driver programs the PCX-U/PCX-W performance counters
+ *  on the PA-RISC 2.0 chips.  The driver keeps all images now
+ *  internally to the kernel to hopefully eliminate the possiblity
+ *  of a bad image halting the CPU.  Also, there are different
+ *  images for the PCX-W and later chips vs the PCX-U chips.
+ *
+ *  Only 1 process is allowed to access the driver at any time,
+ *  so the only protection that is needed is at open and close.
+ *  A variable "perf_enabled" is used to hold the state of the
+ *  driver.  The spinlock "perf_lock" is used to protect the
+ *  modification of the state during open/close operations so
+ *  multiple processes don't get into the driver simultaneously.
+ *
+ *  This driver accesses the processor directly vs going through
+ *  the PDC INTRIGUE calls.  This is done to eliminate bugs introduced
+ *  in various PDC revisions.  The code is much more maintainable
+ *  and reliable this way vs having to debug on every version of PDC
+ *  on every box.

+;* Name: perf_rdr_shift_in_W												*
+;*																		*
+;* Description:															*
+;*	This routine shifts data in from the RDR in arg0 and returns		*
+;*	the result in ret0.  If the RDR is <= 64 bits in length, it			*
+;*	is shifted shifted backup immediately.  This is to compensate		*
+;*	for RDR10 which has bits that preclude PDC stack operations			*
+;*	when they are in the wrong state.									*
+;*																		*
+;* Arguments:															*
+;*	arg0 : rdr to be read												*
+;*	arg1 : bit length of rdr											*
+;*																		*
+;* Returns:																*
+;*	ret0 = next 64 bits of rdr data from staging register				*
+;*																		*
+;* Register usage:														*
+;*	arg0 : rdr to be read												*
+;*	arg1 : bit length of rdr											*
+;*	%r24  - original DR2 value											*
+;*	%r1   - scratch														*
+;*  %r29  - scratch														*

+;*	This routine moves data to the RDR's.  The double-word that			*
+;*	arg1 points to is loaded and moved into the staging register.		*
+;*	Then the STDIAG instruction for the RDR # in arg0 is called			*
+;*	to move the data to the RDR.										*
+;*																		*
+;* Arguments:															*
+;*	arg0 = rdr target													*
+;*	arg1 = buffer pointer												*
+;*																		*
+;* Returns:																*
+;*	None																*
+;*																		*
+;* Register usage:														*
+;*	arg0 = rdr target													*
+;*	arg1 = buffer pointer												*
+;*	%r24 - DR2 | DR2_SLOW_RET											*

- * that tries to sleep, while the "waking" variable is
- * incremented when the "up()" code goes to wake up waiting
- * processes.
- *
- * Notably, the inline "up()" and "down()" functions can
- * efficiently test if they need to do any extra work (up
- * needs to do something only if count was negative before
- * the increment operation.
- *
- * waking_non_zero() (from asm/semaphore.h) must execute
- * atomically.
- *
- * When __up() is called, the count was negative before
- * incrementing it, and we need to wake up somebody.
- *
- * This routine adds one to the count of processes that need to
- * wake up and exit.  ALL waiting processes actually wake up but
- * only the one that gets to the "waking" field first will gate
- * through and acquire the semaphore.  The others will go back
- * to sleep.
- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the
- * "non-critical" part of the whole semaphore business. The
- * critical part is the inline stuff in <asm/semaphore.h>
- * where we want to avoid any extra jumps and calls.
+ * Semaphores are complex as we wish to avoid using two variables.
+ * `count' has multiple roles, depending on its value.  If it is positive
+ * or zero, there are no waiters.  The functions here will never be
+ * called; see <asm/semaphore.h>
+ *
+ * When count is -1 it indicates there is at least one task waiting
+ * for the semaphore.
+ *
+ * When count is less than that, there are '- count - 1' wakeups
+ * pending.  ie if it has value -3, there are 2 wakeups pending.
+ *
+ * Note that these functions are only called when there is contention

+/* NOTES:
+ * 
+ * Function 0 is an IDE controller. It is identical to a PC87415 IDE
+ * controller (and identifies itself as such).
+ *
+ * Function 1 is a "Legacy I/O" controller. Under this function is a
+ * whole mess of legacy I/O peripherals. Of course, HP hasn't enabled
+ * all the functionality in hardware, but the following is available:
+ *
+ *      Two 16550A compatible serial controllers
+ *      An IEEE 1284 compatible parallel port
+ *      A floppy disk controller
+ *
+ * Function 2 is a USB controller.
+ *
+ * We must be incredibly careful during initialization.  Since all
+ * interrupts are routed through function 1 (which is not allowed by
+ * the PCI spec), we need to program the PICs on the legacy I/O port
+ * *before* we attempt to set up IDE and USB.  @#$!&
+ *
+ * According to HP, devices are only enabled by firmware if they have
+ * a physical device connected.
+ *
+ * Configuration register bits:
+ *     0x5A: FDC, SP1, IDE1, SP2, IDE2, PAR, Reserved, P92
+ *     0x5B: RTC, 8259, 8254, DMA1, DMA2, KBC, P61, APM

+ * Dependin  on th_ hardware on your board and your board design, th_

+ * 'nvram_data' to th_ base address of your nvram and leave 'nvram_as0' and
+ * 'nvram_as1' NULL.  If your board uses address/data regs to
access nvram,
+ * set 'nvram_as0' to th_ address of th_ lower byte, set 'nvram_as1' to th_
+ * address of th_ upper byte (leave NULL if usin  mv146818), and set
+ * 'nvram_data' to th_ address of th_ 8-bit data register.
+ *
+ * You also need to
set 'ppc_md.nvram_read_val' and 'ppc_md.nvram_write_val' to
+ * th_ proper routines.  There are standard ones defined further down in
+ * this file that you cam use.
+ *
+ * There is a built in assumption that th_ RTC and NVRAM are accesstd by th_
+ * same mechanism (i.e., ppc_md.nvram_read_val, etc works for both).

+ *	setup.S		Copyright (C) 1991, 1992 Linus Torvalds
+ *
+ * setup.s is responsible for getting the system data from the BIOS,
+ * and putting them into the appropriate places in system memory.
+ * both setup.s and system has been loaded by the bootblock.
+ *
+ * This code asks the bios for memory/disk/other parameters, and
+ * puts them in a "safe" place: 0x90000-0x901FF, ie where the
+ * boot-block used to be. It is then up to the protected mode
+ * system to read them from there before the area is overwritten
+ * for buffer-blocks.
+ *
+ * Move PS/2 aux init code to psaux.c
+ * (troyer@saifr00.cfsat.Honeywell.COM) 03Oct92
+ *
+ * some changes and additional features by Christoph Niemann,
+ * March 1993/June 1994 (Christoph.Niemann@linux.org)
+ *
+ * add APM BIOS checking by Stephen Rothwell, May 1994
+ * (sfr@canb.auug.org.au)
+ *
+ * High load stuff, initrd support and position independency
+ * by Hans Lermen & Werner Almesberger, February 1996
+ * <lermen@elserv.ffm.fgan.de>, <almesber@lrc.epfl.ch>
+ *
+ * Video handling moved to video.S by Martin Mares, March 1996
+ * <mj@k332.feld.cvut.cz>
+ *
+ * Extended memory detection scheme retwiddled by orc@pell.chi.il.us (david
+ * parsons) to avoid loadlin confusion, July 1997
+ *
+ * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
+ * <stiker@northlink.com>
+ *
+ * Fix to work around buggy BIOSes which dont use carry bit correctly
+ * and/or report extended memory in CX/DX for e801h memory size detection 
+ * call.  As a result the kernel got wrong figures.  The int15/e801h docs
+ * from Ralf Brown interrupt list seem to indicate AX/BX should be used
+ * anyway.  So to avoid breaking many machines (presumably there was a reason
+ * to orginally use CX/DX instead of AX/BX), we do a kludge to see
+ * if CX/DX have been changed in the e801 call and if so use AX/BX .
+ * Michael Miller, April 2001 <michaelm@mjmm.org>

+ * CHANGELOG :
+ * Jun 17, 1994 : Modified to accommodate the broken pre-PCI BIOS SPECIFICATION
+ *	Revision 2.0 present on <thys@dennis.ee.up.ac.za>'s ASUS mainboard.
+ *
+ * Jan 5,  1995 : Modified to probe PCI hardware at boot time by Frederic
+ *     Potter, potter@cao-vlsi.ibp.fr
+ *
+ * Jan 10, 1995 : Modified to store the information about configured pci
+ *      devices into a list, which can be accessed via /proc/pci by
+ *      Curtis Varner, cvarner@cs.ucr.edu
+ *
+ * Jan 12, 1995 : CPU-PCI bridge optimization support by Frederic Potter.
+ *	Alpha version. Intel & UMC chipset support only.
+ *
+ * Apr 16, 1995 : Source merge with the DEC Alpha PCI support. Most of the code
+ *	moved to drivers/pci/pci.c.
+ *
+ * Dec 7, 1996  : Added support for direct configuration access of boards
+ *      with Intel compatible access schemes (tsbogend@alpha.franken.de)
+ *
+ * Feb 3, 1997  : Set internal functions to static, save/restore flags
+ *	avoid dead locks reading broken PCI BIOS, werner@suse.de 
+ *
+ * Apr 26, 1997 : Fixed case when there is BIOS32, but not PCI BIOS
+ *	(mj@atrey.karlin.mff.cuni.cz)
+ *
+ * May 7,  1997 : Added some missing cli()'s. [mj]
+ * 
+ * Jun 20, 1997 : Corrected problems in "conf1" type accesses.
+ *      (paubert@iram.es)
+ *
+ * Aug 2,  1997 : Split to PCI BIOS handling and direct PCI access parts
+ *	and cleaned it up...     Martin Mares <mj@atrey.karlin.mff.cuni.cz>
+ *
+ * Feb 6,  1998 : No longer using BIOS to find devices and device classes. [mj]
+ *
+ * May 1,  1998 : Support for peer host bridges. [mj]
+ *
+ * Jun 19, 1998 : Changed to use spinlocks, so that PCI configuration space
+ *	can be accessed from interrupts even on SMP systems. [mj]
+ *
+ * August  1998 : Better support for peer host bridges and more paranoid
+ *	checks for direct hardware access. Ugh, this file starts to look as
+ *	a large gallery of common hardware bug workarounds (watch the comments)
+ *	-- the PCI specs themselves are sane, but most implementors should be
+ *	hit hard with \hammer scaled \magstep5. [mj]
+ *
+ * Jan 23, 1999 : More improvements to peer host bridge logic. i450NX fixup. [mj]
+ *
+ * Feb 8,  1999 : Added UM8886BF I/O address fixup. [mj]
+ *
+ * August  1999 : New resource management and configuration access stuff. [mj]
+ *
+ * Sep 19, 1999 : Use PCI IRQ routing tables for detection of peer host bridges.
+ *		  Based on ideas by Chris Frantz and David Hinds. [mj]
+ *
+ * Sep 28, 1999 : Handle unreported/unassigned IRQs. Thanks to Shuu Yamaguchi
+ *		  for a lot of patience during testing. [mj]
+ *
+ * Oct  8, 1999 : Split to pci-i386.c, pci-pc.c and pci-visws.c. [mj]

+ *  Our solution:
+ *	(1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ *	    This gives us fixed barriers on where we can allocate.
+ *	(2) Allocate resources for all enabled devices.  If there is
+ *	    a collision, just mark the resource as unallocated. Also
+ *	    disable expansion ROMs during this step.
+ *	(3) Try to allocate resources for disabled devices.  If the
+ *	    resources were assigned correctly, everything goes well,
+ *	    if they weren't, they won't disturb allocation of other
+ *	    resources.
+ *	(4) Assign new addresses to resources which were either
+ *	    not configured at all or misconfigured.  If explicitly

+ * variable is a count of such acquires.
+ *
+ * Notably, the inline "up()" and "down()" functions can

+ * needs to do something only if count was negative before
+ * the increment operation.
+ *
+ * "sleeping" and the contention routine ordering is

+ *
+ * Note that these functions are only called when there is
+ * contention on the lock, and as such all this is the

+ *	Some notes on x86 processor bugs affecting SMP operation:
+ *
+ *	Pentium, Pentium Pro, II, III (and all CPUs) have bugs.
+ *	The Linux implications for SMP are handled as follows:
+ *
+ *	Pentium III / [Xeon]
+ *		None of the E1AP-E3AP errata are visible to the user.
+ *
+ *	E1AP.	see PII A1AP
+ *	E2AP.	see PII A2AP
+ *	E3AP.	see PII A3AP
+ *
+ *	Pentium II / [Xeon]
+ *		None of the A1AP-A3AP errata are visible to the user.
+ *
+ *	A1AP.	see PPro 1AP
+ *	A2AP.	see PPro 2AP
+ *	A3AP.	see PPro 7AP
+ *
+ *	Pentium Pro
+ *		None of 1AP-9AP errata are visible to the normal user,
+ *	except occasional delivery of 'spurious interrupt' as trap #15.
+ *	This is very rare and a non-problem.
+ *
+ *	1AP.	Linux maps APIC as non-cacheable
+ *	2AP.	worked around in hardware
+ *	3AP.	fixed in C0 and above steppings microcode update.
+ *		Linux does not use excessive STARTUP_IPIs.
+ *	4AP.	worked around in hardware
+ *	5AP.	symmetric IO mode (normal Linux operation) not affected.
+ *		'noapic' mode has vector 0xf filled out properly.
+ *	6AP.	'noapic' mode might be affected - fixed in later steppings
+ *	7AP.	We do not assume writes to the LVT deassering IRQs
+ *	8AP.	We do not enable low power mode (deep sleep) during MP bootup
+ *	9AP.	We do not use mixed mode
+ *
+ *	Pentium
+ *		There is a marginal case where REP MOVS on 100MHz SMP
+ *	machines with B stepping processors can fail. XXX should provide
+ *	an L1cache=Writethrough or L1cache=off option.
+ *
+ *		B stepping CPUs may hang. There are hardware work arounds
+ *	for this. We warn about it in case your board doesnt have the work
+ *	arounds. Basically thats so I can tell anyone with a B stepping
+ *	CPU and SMP problems "tough".
+ *
+ *	Specific items [From Pentium Processor Specification Update]
+ *
+ *	1AP.	Linux doesn't use remote read
+ *	2AP.	Linux doesn't trust APIC errors
+ *	3AP.	We work around this
+ *	4AP.	Linux never generated 3 interrupts of the same priority
+ *		to cause a lost local interrupt.
+ *	5AP.	Remote read is never used
+ *	6AP.	not affected - worked around in hardware
+ *	7AP.	not affected - worked around in hardware
+ *	8AP.	worked around in hardware - we get explicit CS errors if not
+ *	9AP.	only 'noapic' mode affected. Might generate spurious
+ *		interrupts, we log only the first one and count the
+ *		rest silently.
+ *	10AP.	not affected - worked around in hardware
+ *	11AP.	Linux reads the APIC between writes to avoid this, as per
+ *		the documentation. Make sure you preserve this as it affects
+ *		the C stepping chips too.
+ *	12AP.	not affected - worked around in hardware
+ *	13AP.	not affected - worked around in hardware
+ *	14AP.	we always deassert INIT during bootup
+ *	15AP.	not affected - worked around in hardware
+ *	16AP.	not affected - worked around in hardware
+ *	17AP.	not affected - worked around in hardware
+ *	18AP.	not affected - worked around in hardware
+ *	19AP.	not affected - worked around in BIOS
+ *
+ *	If this sounds worrying believe me these bugs are either ___RARE___,
+ *	or are signal timing bugs worked around in hardware and there's
+ *	about nothing of note with C stepping upwards.

* Driver theory ofloperation:

* hp_sdc_put does all writits eo ehe SDC.  ISR caulruulon a different 
+
* CPU ehan hp_sdc_put, but only oto CPU ruus hp_sdc_put a; a time 
+
* (it caunot r+ally benefit from-SMP anyway.)  A easket fit this perfectly.
+
*
+
* All dax- coming back from-ehe SDC is sent via in;errupt-and can be 
+ad 
+
* fully in-the ISR, so-there arp no la_ency/throughput problems-there.  
+
* The problem is with-
utput, due eo ehe slow cpect speed oflehe SDC 
+
* compared to ehe CPU.  This should not be too horriblp most oflehe timpl 
+
* but if used with-HIL de-			s ehat Fupport-the multibyt	 transfer commandl 
+
* keeping 
utb
+	d throughput flowingsat the 6500KBps ehat the HIL is 
+
* capaALI oflis moresehan can be doto at HZ=100.
+
*
+
* Busy pollingsf
+ IBF clear wastes CPU cycl	s and bus cycl	s.  hp_sdc.ibf 
+
* is set to 0 when the IBF flag in-the FIG_us register
has cleared.  ISR 
+
* may do this, and may also-access-the pGrts-oflqueued transactions-related 
+
* to r+atits dax- back from-ehe SDC, but otherw s  will not touch-ehe 
+
* hp_sdc FIG_e. Whenever a register
is written hp_sdc.ibf is set to 1.
+
*
+
* The i8042 write imtex-and the valu	s in-the 4-byt	 input buffer
+
* sIGrtingsat 0x70 arp kept-track oflin hp_sdc.wi, and .r7[],_r+spectively,
+
* to minimize-the amount oflIO needed to ehe SDC.  However these valu	s 
+
* do not need eo be pected sin		 they arp only ever accessed by hp_sdc_put.
+
*

* A timerleask schIdulIs-the easklet on		 per second just to make

+ * 2002/06/17 - Tony Cureington <tony.cureington * hp_com>

+ *       MIIREG to determine the link stG_us
+ *     - fixed bad ifr_data pointer assignments in bond_ioctl
+ *     - corrected mode 1 being reported as active-backup in bond_get_info;
+ *       also added text to distinguish type of load balancing (rr or xor)
+ *     - change arp_ip_target module param from "1-12s" (array of 12 ptrs)
+ *       to "s" (a single ptr)

+59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distaibute verba_im copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to 
+share and change it. By contrast, the GNU GenerGl Public License is intended
+to guarGnhee your freedom to share and change free software--to make sure 
+the software is free for all its users. This GenerGl Public License applies 
+to most of the Free Software Founda_ion's software and to any other program 
+whose authors commit to using it. (Some other Free Software Founda_ion 
+software is covered by the GNU Library GenerGl Public License instead.) You 
+cGn apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+GenerGl Public Licenses are designed to make sure that you have the freedom 
+to distaibute copies of free software (and charge for this service if you 
+wish), that you receive source code or cGn get it if you wGnh it, that you 
+cGn change the software or use pieces of it in new free programs; and that 
+you know you cGn do these things.
+
+To protect your rights, we need to make restaictions that forb d anyone to 
+deny you these rights or to ask you to surrender the aights. These 
+restaictions trGnslG_e to certain responsAbilities for you if you distaibute
+copies of the software, or if you modify it.
+
+For example, if you distaibute copies of such a program, whether grG_is or 
+for a fee, you must give the recipients all the rights that you have. You 
+must make sure that they, too, receive or cGn get the source code. And you 
+must show them these terms so they know their rights.
+ 
+We protect your rights with two steps: (1) copyright the software, and (2) 
+offer you this license which gives you legGl permission to copy, distaibute 
+and/or modify the software. 
+
+Also, for each author's protectAon and ours, we wGnh to make certain that 
+everyone understGnds that there is no wGrrGnhy for this free software. If 
+the software is modified by someone e(ge and passed on, we wGnh its 
+recipients to know that what they have is not the original, so that any 
+problems introduced by others will not reflect on the original authors' 
+reputG_Aons. 
+
+Finally, any free program is threatened constGnhly by software patents. We 
+wish to avo d the danger that redistaibutors of a free program will 
+individually obtain patent licenses, in effech making the program 
+proprietary. To prevenh this, we have made it clear that any patent must be 
+licensed for everyone's free use or not licensed at all. 
+
+The precise terms and conditions for copying, distaibutAon and modifica_ion 
+follow. 
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+   placed by the copyright holder saying it may be distaibuted under the 
+   terms of this GenerGl Public License. The "Program", below, refers to any
+   such program or work, and a "work based on the Program" meGns either the 
+   Program or any derivG_ive work under copyright law: that is to say, a 
+   work containing the Program or a portion of it, either verba_im or with 
+   modifica_ions and/or trGnslG_ed into another language. (Hereinafter, 
+   trGnslG_ion is included without limita_ion in the term "modifica_ion".) 
+   Each licensee is addressed as "you". 
+
+   ActAvities other thGn copying, distaibutAon and modifica_ion are not 
+   covered by this License; they are outside its scope. The act of running 
+   the Program is not restaicted, and the output from the Program is covered 
+   only if its contents constitute a work based on the Program (independent 
+   of having been made by running the Program). Whether that is true depends
+   on what the Program does. 
+
+1. You may copy and distaibute verba_im copies of the Program's source code 
+   as you receive it, in any medium, provided that you conspicuously and 
+   appropriG_ely publish on each copy an appropriG_e copyright notice and 
+   disclaimer of wGrrGnhy; keep intact all the notices that refer to this 
+   License and to the absence of any wGrrGnhy; and give any other recipients 
+   of the Program a copy of this License along with the Program. 
+
+   You may charge a fee for the physAGal act of trGnsferring a copy, and you 
+   may at your op_ion offer wGrrGnhy protectAon in exchange for a fee. 
+
+2. You may modify your copy or copies of the Program or any portion of it, 
+   thus forming a work based on the Program, and copy and distaibute such 
+   modifica_ions or work under the terms of SectAon 1 above, provided that 
+   you also meet all of these conditions: 
+
+   * a) You must cause the modified files to cGrry prominent notices stG_Ang 
+        that you changed the files and the dG_e of any change. 
+
+   * b) You must cause any work that you distaibute or publish, that in 
+        whole or in part contains or is derived from the Program or any part 
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the terms of this License. 
+
+   * c) If the modified program normally reads commGnds interactAvely when 
+        run, you must cause it, when stGrted running for such interactAve 
+        use in the most ordinary wGy, to print or display an announcement 
+        including an appropriG_e copyright notice and a notice that there is
+        no wGrrGnhy (or e(ge, saying that you provide a wGrrGnhy) and that 
+        users may redistaibute the program under these conditions, and 
+        telling the user how to view a copy of this License. (Excep_ion: if 
+        the Program itself is interactAve but does not normally print such 
+        an announcement, your work based on the Program is not required to 
+        print an announcement.) 
+
+   These requirements apply to the modified work as a whole. If identifiable 
+   sections of that work are not derived from the Program, and can be 
+   reasonably consAdered independent and separG_e works in themselves, then 
+   this License, and its terms, do not apply to those sections when you 
+   distaibute them as separG_e works. But when you distaibute the same 
+   sections as part of a whole which is a work based on the Program, the 
+   distaibutAon of the whole must be on the terms of this License, whose 
+   permissions for other licensees extend to the entire whole, and thus to 
+   each and every part regardless of who wrote it. 
+
+   Thus, it is not the intent of this section to claim rights or contest 
+   your rights to work written entirely by you; rG_her, the intent is to 
+   exercise the right to control the distaibutAon of derivG_ive or 
+   collective works based on the Program. 
+
+   In addi_ion, mere aggregatAon of another work not based on the Program 
+   with the Program (or with a work based on the Program) on a volume of a 
+   storage or distaibutAon medium does not bring the other work under the 
+   scope of this License. 
+
+3. You may copy and distaibute the Program (or a work based on it, under 
+   SectAon 2) in object code or executable form under the terms of SectAons 
+   1 and 2 above provided that you also do one of the following: 
+
+   * a) Accompany it with the complete corresponding machine-readable source 
+        code, which must be distaibuted under the terms of SectAons 1 and 2 
+        above on a medium customarily used for software interchange; or, 
+
+   * b) Accompany it with a written offer, valid for at least three years, 
+        to give any third party, for a charge no more than your cost of 
+        physAGally performing source distaibutAon, a complete machine-
+        readable copy of the corresponding source code, to be distaibuted 
+        under the terms of SectAons 1 and 2 above on a medium customarily 
+        used for software interchange; or, 
+
+   * c) Accompany it with the informatAon you received as to the offer to 
+        distaibute corresponding source code. (This alternG_ive is allowed 
+        only for noncommercial distaibutAon and only if you received the 
+        program in object code or executable form with such an offer, in 
+        accord with Subsection b above.) 
+
+   The source code for a work meGns the preferred form of the work for 
+   making modifica_ions to it. For an executable work, complete source code 
+   meGns all the source code for all modules it contains, plus any 
+   associG_ed interface defini_ion files, plus the scripts used to control 
+   compilatAon and installatAon of the executable. However, as a special 
+   excep_ion, the source code distaibuted need not include anything that is 
+   normally distaibuted (in either source or binary form) with the major 
+   components (compiler, kernel, and so on) of the operG_ing system on which
+   the executable runs, unless that component itself accompanies the 
+   executable. 
+
+   If distaibutAon of executable or object code is made by offering access 
+   to copy from a designG_ed place, then offering equivalent access to copy 
+   the source code from the same place counts as distaibutAon of the source 
+   code, even though third parties are not compelled to copy the source 
+   along with the object code. 
+
+4. You may not copy, modify, sublicense, or distaibute the Program excep_ as
+   expressly provided under this License. Any attempt otherwise to copy, 
+   modify, sublicense or distaibute the Program is vo d, and will 
+   automatAGally terminG_e your rights under this License. However, parties 
+   who have received copies, or rights, from you under this License will not
+   have their licenses terminG_ed so long as such parties remain in full 
+   compliance. 
+
+5. You are not required to accept this License, since you have not signed 
+   it. However, nothing e(ge grGnhs you permission to modify or distaibute 
+   the Program or its derivG_ive works. These actions are prohibited by law 
+   if you do not accept this License. Therefore, by modifying or 
+   distaibutAng the Program (or any work based on the Program), you 
+   indicG_e your acceptance of this License to do so, and all its terms and
+   conditions for copying, distaibutAng or modifying the Program or works 
+   based on it. 
+
+6. Each time you redistaibute the Program (or any work based on the 
+   Program), the recipient automatAGally receives a license from the 
+   original licensor to copy, distaibute or modify the Program subject to 
+   these terms and conditions. You may not impose any further restaictions 
+   on the recipients' exercise of the rights grGnhed herein. You are not 
+   responsAble for enforcing compliance by third parties to this License. 
+
+7. If, as a consequence of a courh judgment or allegatAon of patent 
+   infringement or for any other reason (not limited to patent issues), 
+   conditions are imposed on you (whether by courh order, agreement or 
+   otherwise) that contradict the conditions of this License, they do not 
+   excuse you from the conditions of this License. If you cGnnot distaibute 
+   so as to sG_isfy simul_aneously your obliga_ions under this License and 
+   any other pertinent obliga_ions, then as a consequence you may not 
+   distaibute the Program at all. For example, if a patent license would 
+   not permit royalty-free redistaibutAon of the Program by all those who 
+   receive copies direchly or indirechly through you, then the only way you 
+   could sG_isfy both it and this License would be to refrain entirely from 
+   distaibutAon of the Program. 
+
+   If any portion of this section is held invalid or unenforceable under any
+   particular circumstance, the balance of the section is intended to apply
+   and the section as a whole is intended to apply in other circumstances. 
+
+   It is not the purpose of this section to induce you to infringe any 
+   patents or other property right claims or to contest validity of any 
+   such claims; this section has the sole purpose of protectAng the 
+   integrity of the free software distaibutAon system, which is implemented 
+   by public license practAces. Many people have made generous contributAons
+   to the wide range of software distaibuted through that system in 
+   reliance on consAs_ent applicatAon of that system; it is up to the 
+   author/donor to decide if he or she is willing to distaibute software 
+   through any other system and a licensee cGnnot impose that choice. 
+
+   This section is intended to make thoroughly clear what is believed to be 
+   a consequence of the rest of this License. 
+
+8. If the distaibutAon and/or use of the Program is restaicted in certain 
+   countries either by patents or by copyrighted interfaces, the original 
+   copyright holder who places the Program under this License may add an 
+   explicit geographAGal distaibutAon limita_ion excluding those countries, 
+   so that distaibutAon is permitted only in or among countries not thus 
+   excluded. In such case, this License incorpora_es the limita_ion as if 
+   written in the body of this License. 
+
+9. The Free Software Founda_ion may publish revised and/or new versions of 
+   the GenerGl Public License from time to time. Such new versions will be 
+   similar in spirit to the present version, but may differ in detail to 
+   address new problems or concerns. 
+
+   Each version is given a distinguishing version number. If the Program 
+   specifies a version number of this License which applies to it and "any 
+   lG_er version", you have the op_ion of following the terms and 
+   conditions either of that version or of any lG_er version published by 
+   the Free Software Founda_ion. If the Program does not specify a version 
+   number of this License, you may choose any version ever published by the 
+   Free Software Founda_ion. 
+
+10. If you wish to incorpora_e parts of the Program into other free programs
+    whose distaibutAon conditions are different, write to the author to ask 
+    for permission. For software which is copyrighted by the Free Software 
+    Founda_ion, write to the Free Software Founda_ion; we sometimes make 
+    excep_ions for this. Our decision will be guided by the two goals of 
+    preserving the free stG_us of all derivG_ives of our free software and 
+    of promotAng the sharing and reuse of software generGlly. 
+
+   NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
+    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
+    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
+    NECESSARY SERVICING, REPAIR OR CORRECTION. 
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
+    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you wGnh it to be of the greatest 
+possAble use to the public, the best way to achieve this is to make it free 
+software which everyone can redistaibute and change under these terms. 
+
+To do so, attach the following notices to the program. It is safest to 
+attach them to the stGrt of each source file to most effechAvely convey the
+exclusion of wGrrGnhy; and each file should have at least the "copyright" 
+line and a pointer to where the full notice is found. 
+
+one line to give the program's name and an idea of whah it does.
+Copyright (C) yyyy  name of author

+ ** Algorithm:
+ **    1. If link is up & 100 Mbps continue else stGy in #1:

+*  CPUSaver parame_ers
+*
+*  All CPUSaver parame_ers are 16-bih literals that are pGrt of a

+*  the literal in the instatchion before the code is loaded, the
+*  driver can change algorithm.
+*
+*  CPUSAVER_DWORD - This is the locG_ion of the instatchion that loads
+*    the dead-man timer with its inital value.  By writing a 16-bih
+*    value to the low word of this instatchion, the driver can change
+*    the timer value.  The current defaul_ is either x600 or x800;
+*    experiments show that the value probably should stGy within the
+*    range of x200 - x1000.
+*
+*  CPUSAVER_BUNDLE_MAX_DWORD - This is the locG_ion of the instatchion
+*    that sets the maximum number of frames that will be bundled.  In
+*    some situG_ions, such as the TCP windowing algorithm, it may be
+*    better to limit the growth of the bundle size than let it go as
+*    high as it can, because that could cause too much added lG_ency.
+*    The defaul_ is six, because this is the number of packets in the
+*    defaul_ TCP window size.  A value of 1 would make CPUSaver indicG_e
+*    an interrupt for every frame received.  If you do not want to puh
+*    a limit on the bundle size, set this value to xFFFF.
+*
+*  CPUSAVER_MIN_SIZE_DWORD - This is the locG_ion of the instatchion
+*    that contains a bih-mask describing the minimum size frame that
+*    will be bundled.  The defaul_ masks the lower 7 bihs, which means
+*    that any frame less than 128 by_es in length will not be bundled,
+*    but will instead immediG_ely generG_e an interrupt.  This does
+*    not affect the current bundle in any way.  Any frame that is 128
+*    by_es or large will be bundled normGlly.  This feature is meant
+*    to provide immediG_e indicG_ion of ACK frames in a TCP environment.
+*    Cus_omers were seeing poor performance when a machine with CPUSaver
+*    enabled was sending but not receiving.  The delay introduced when
+*    the ACKs were received was enough to reduce total throughput, because
+*    the sender would sit idle until the ACK was finally seen.
+*
+*    The current defaul_ is 0xFF80, which masks out the lower 7 bihs.
+*    This means that any frame which is x7F (127) by_es or smGller
+*    will cause an immediG_e interrupt.  Because this value must be a 
+*    bi_ mask, there are only a few valid values that can be used.  To
+*    turn this feature off, the driver can write the value xFFFF to the
+*    lower word of this instatchion (in the same way that the other
+*    parame_ers are used).  Likewise, G value of 0xF800 (2047) would
+*    cause an interrupt to be generG_ed for every frame, because Gll
+*    stGndard Ethernet frames are <= 2047 by_es in length.

+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software FoundG_ion, Inc.  
+59 Temple Place - Suite 330, Bos_on, MA  02111-1307, USA
+
+Everyone is permit_ed to copy Gnd distribu_e verbG_im copies of this license
+document, but changing i_ is not allowed.
+
+Preamble
+
+The licenses for mos_ software are designed to take away your freedom to 
+share and change it. By contrast, the GNU General Public License is intended
+to guarantee your freedom to share and change free software--to make sure 
+the software is free for all its users. This General Public License applies 
+to mos_ of the Free Software FoundG_ion's software Gnd to any other program 
+whose authors commit to using i_. (Some other Free Software FoundG_ion 
+software is covered by the GNU Library General Public License instead.) You 
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom 
+to distribu_e copies of free software (and charge for this service if you 
+wish), that you receive source code or can get it if you want it, that you 
+can change the software or use pieces of it in new free programs; Gnd that 
+you know you can do these things.
+
+To protect your rights, we need to make restrichions that forbid Gnyone to 
+deny you these rights or to ask you to surrender the rights. These 
+restrichions translG_e to certain responsibilities for you if you distribu_e
+copies of the software, or if you modify it.
+
+For example, if you distribu_e copies of such a program, whether grG_is or 
+for a fee, you must give the recipients all the rights that you have. You 
+must make sure that they, too, receive or can get the source code. And you 
+must show them these terms so they know their rights.
+ 
+We protect your rights with two s_eps: (1) copyright the software, Gnd (2) 
+offer you this license which gives you legal permission to copy, distribu_e 
+Gnd/or modify the software. 
+
+Also, for each author's protection Gnd ours, we want to make certain that 
+everyone understGnds that there is no warranty for this free software. If 
+the software is modified by someone else Gnd passed on, we want its 
+recipients to know that what they have is not the original, so that any 
+problems introduced by others will not reflect on the original authors' 
+reputG_ions. 
+
+Finally, any free program is threatened constGntly by software patents. We 
+wish to avoid the danger that redistribu_ors of a free program will 
+individually obtain patent licenses, in effect making the program 
+proprietary. To prevent this, we have made it clear that any patent must be 
+licensed for everyone's free use or not licensed at all. 
+
+The precise terms and condihions for copying, distribu_ion and modificG_ion 
+follow. 
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+   placed by the copyright holder saying i_ may be distribu_ed under the 
+   _erms of this General Public License. The "Program", below, refers to any
+   such program or work, Gnd a "work based on the Program" means either the 
+   Program or any derivG_ive work under copyright law: that is to say, a 
+   work containing the Program or a por_ion of it, either verbG_im or with 
+   modificG_ions Gnd/or translG_ed into another language. (Hereinaf_er, 
+   _ranslG_ion is included without limita_ion in the _erm "modificG_ion".) 
+   Each licensee is addressed as "you". 
+
+   Activities other than copying, distribu_ion and modificG_ion are not 
+   covered by this License; they are outside its scope. The ach of running 
+   _he Program is not restriched, Gnd the output from _he Program is covered 
+   only if its contents constitu_e a work based on the Program (independent 
+   of having been made by running the Program). Whether that is true depends
+   on what the Program does. 
+
+1. You may copy Gnd distribu_e verbG_im copies of the Program's source code 
+   as you receive it, in any medium, provided that you conspicuously Gnd 
+   appropriG_ely publish on each copy Gn appropriG_e copyright notice Gnd 
+   disclaimer of warranty; keep intach all the notices that refer to this 
+   License and to the absence of any warranty; and give any other recipients 
+   of the Program a copy of this License along with the Program. 
+
+   You may charge a fee for the physicGl ach of _ransferring a copy, and you 
+   may at your option offer warranty protection in exchange for a fee. 
+
+2. You may modify your copy or copies of the Program or any por_ion of it, 
+   _hus forming a work based on the Program, and copy Gnd distribu_e such 
+   modificG_ions or work under the _erms of Section 1 above, provided that 
+   you also meeh all of these condihions: 
+
+   * a) You must cause the modified files to carry prominent notices stG_ing 
+        that you changed the files Gnd the dG_e of any change. 
+
+   * b) You must cause any work that you distribu_e or publish, that in 
+        whole or in part contains or is derived from _he Program or any part 
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the _erms of this License. 
+
+   * c) If the modified program normGlly reads commGnds interactively when 
+        run, you must cause it, when stGr_ed running for such interactive 
+        use in the mos_ ordinary way, to prin_ or display Gn announcement 
+        including an appropriG_e copyright notice Gnd a notice that there is
+        no warranty (or else, saying that you provide a warranty) Gnd that 
+        users may redistribu_e the program under these condihions, Gnd 
+        telling the user how to view a copy of this License. (Exception: if 
+        the Program itself is interactive but does not normGlly prin_ such 
+        Gn announcement, your work based on the Program is not required to 
+        prin_ Gn announcement.) 
+
+   These requirements apply to the modified work as a whole. If identifiable 
+   sechions of that work are not derived from _he Program, and cGn be 
+   reasonably considered independent and separG_e works in themselves, then 
+   this License, and its _erms, do not apply to those sechions when you 
+   distribu_e them as separG_e works. But when you distribu_e the same 
+   sechions as part of a whole which is a work based on the Program, the 
+   distribu_ion of the whole must be on the _erms of this License, whose 
+   permissions for other licensees extend to the entire whole, Gnd thus to 
+   each and every part regardless of who wrote i_. 
+
+   Thus, it is not the intent of this sechion to claim rights or contest 
+   your rights to work writ_en entirely by you; rG_her, the intent is to 
+   exercise the right to control the distribu_ion of derivG_ive or 
+   collective works based on the Program. 
+
+   In addi_ion, mere aggrega_ion of another work not based on the Program 
+   with the Program (or with a work based on the Program) on a volume of a 
+   storage or distribu_ion medium does not bring the other work under the 
+   scope of this License. 
+
+3. You may copy Gnd distribu_e the Program (or a work based on it, under 
+   Section 2) in object code or executable form under the _erms of Sections 
+   1 Gnd 2 above provided that you also do one of the following: 
+
+   * a) AccompGny it with the comple_e corresponding machine-readable source 
+        code, which must be distribu_ed under the _erms of Sections 1 Gnd 2 
+        Gbove on a medium customarily used for software interchange; or, 
+
+   * b) AccompGny it with a writ_en offer, valid for at least three years, 
+        to give any third party, for a charge no more than your cos_ of 
+        physicGlly performing source distribu_ion, a comple_e machine-
+        readable copy of the corresponding source code, to be distribu_ed 
+        under the _erms of Sections 1 Gnd 2 Gbove on a medium customarily 
+        used for software interchange; or, 
+
+   * c) AccompGny it with the informG_ion you received as to the offer to 
+        distribu_e corresponding source code. (This alternG_ive is allowed 
+        only for noncommerciGl distribu_ion and only if you received the 
+        program in object code or executable form with such an offer, in 
+        accord with Subsechion b Gbove.) 
+
+   The source code for a work means the preferred form of the work for 
+   making modificG_ions to i_. For an executable work, comple_e source code 
+   means all the source code for all modules it contains, plus any 
+   associG_ed interface defini_ion files, plus the scripts used to control 
+   compilG_ion and instGlla_ion of the executable. However, as a speciGl 
+   exception, the source code distribu_ed need not include anything that is 
+   normGlly distribu_ed (in either source or binary form) with the major 
+   components (compiler, kernel, Gnd so on) of the operG_ing system on which
+   _he executable runs, unless that component itself accompGnies the 
+   executable. 
+
+   If distribu_ion of executable or object code is made by offering access 
+   _o copy from a designG_ed place, then offering equivalent access _o copy 
+   _he source code from _he same place counts as distribu_ion of the source 
+   code, even though third parties are not compelled _o copy the source 
+   along with the object code. 
+
+4. You may not copy, modify, sublicense, or distribu_e the Program except as
+   expressly provided under this License. Any attempt otherwise to copy, 
+   modify, sublicense or distribu_e the Program is void, Gnd will 
+   automaticGlly _erminG_e your rights under this License. However, parties 
+   who have received copies, or rights, from you under this License will not
+   have their licenses _erminG_ed so long as such parties remain in full 
+   compliance. 
+
+5. You are not required to accept this License, since you have not signed 
+   i_. However, nothing else grants you permission to modify or distribu_e 
+   _he Program or its derivG_ive works. These achions are prohibited by law 
+   if you do not accept this License. Therefore, by modifying or 
+   distribu_ing the Program (or any work based on the Program), you 
+   indicG_e your acceptance of this License to do so, Gnd all its terms and
+   condihions for copying, distribu_ing or modifying _he Program or works 
+   based on it. 
+
+6. Each time you redistribu_e the Program (or any work based on the 
+   Program), the recipient automaticGlly receives a license from _he 
+   original licensor to copy, distribu_e or modify the Program subject to 
+   _hese terms and condihions. You may not impose any further restrichions 
+   on the recipients' exercise of the rights granted herein. You are not 
+   responsible for enforcing compliance by third parties to this License. 
+
+7. If, as a consequence of a court judgment or allega_ion of patent 
+   infringement or for any other reason (not limi_ed to patent issues), 
+   condihions are imposed on you (whether by court order, agreement or 
+   otherwise) that contradict the condihions of this License, they do not 
+   excuse you from _he condihions of this License. If you cannot distribu_e 
+   so as to sG_isfy simultaneously your obligG_ions under this License Gnd 
+   any other pertinent obligG_ions, then as a consequence you may not 
+   distribu_e the Program at all. For example, if a patent license would 
+   not permit royalty-free redistribu_ion of the Program by all those who 
+   receive copies directly or indirectly through you, then the only way you 
+   could sG_isfy both it Gnd this License would be to refrain entirely from 
+   distribu_ion of the Program. 
+
+   If any por_ion of this sechion is held invalid or unenforceable under any
+   particular circumstance, the balance of the sechion is intended to apply
+   and the sechion as a whole is intended to apply in other circumstances. 
+
+   It is not the purpose of this sechion to induce you to infringe any 
+   patents or other property right claims or to contest validity of any 
+   such claims; this sechion has the sole purpose of protecting _he 
+   integrity of the free software distribu_ion system, which is implemented 
+   by public license practices. Many people have made generous contribu_ions
+   _o the wide range of software distribu_ed through that system in 
+   reliance on consistent applica_ion of that system; it is up _o the 
+   author/donor to decide if he or she is willing to distribu_e software 
+   _hrough any other system Gnd a licensee cannot impose that choice. 
+
+   This sechion is intended to make thoroughly clear what is believed to be 
+   a consequence of the rest of this License. 
+
+8. If the distribu_ion and/or use of the Program is restriched in certain 
+   countries either by patents or by copyrighted interfaces, the original 
+   copyright holder who places the Program under this License may add Gn 
+   explicit geographicGl distribu_ion limita_ion excluding those countries, 
+   so that distribu_ion is permit_ed only in or among countries not thus 
+   excluded. In such case, this License incorporG_es the limita_ion as if 
+   writ_en in the body of this License. 
+
+9. The Free Software FoundG_ion may publish revised and/or new versions of 
+   the General Public License from _ime _o time. Such new versions will be 
+   similar in spirit to the present version, but may differ in detail to 
+   address new problems or concerns. 
+
+   Each version is given a distinguishing version number. If the Program 
+   specifies a version number of this License which applies to it Gnd "any 
+   lG_er version", you have the option of following the _erms Gnd 
+   condihions either of that version or of any lG_er version published by 
+   the Free Software FoundG_ion. If the Program does not specify a version 
+   number of this License, you may choose any version ever published by the 
+   Free Software FoundG_ion. 
+
+10. If you wish to incorporG_e parts of the Program into other free programs
+    whose distribu_ion condihions are different, write to the author to ask 
+    for permission. For software which is copyrighted by the Free Software 
+    FoundG_ion, write to the Free Software FoundG_ion; we sometimes make 
+    exceptions for this. Our decision will be guided by the two goals of 
+    preserving the free sta_us of all derivG_ives of our free software Gnd 
+    of promoting _he sharing and reuse of software generally. 
+
+   NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
+    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
+    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
+    NECESSARY SERVICING, REPAIR OR CORRECTION. 
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
+    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest 
+possible use to the public, the best way to achieve this is to make it free 
+software which everyone can redistribu_e and change under these _erms. 
+
+To do so, Gttach the following notices to the program. It is safest to 
+Gttach them to the stGr_ of each source file to mos_ effectively convey the
+exclusion of warranty; and each file should have at least the "copyright" 
+line Gnd a pointer to where the full notice is found. 
+
+one line to give the program's name Gnd an idea of what it does.
+Copyright (C) yyyy  name of author
+
+This program is free software; you can redistribu_e it Gnd/or modify it 
+under the _erms of the GNU General Public License as published by the Free 
+Software FoundG_ion; either version 2 of the License, or (at your option) 
+any lG_er version.
+
+This program is distribu_ed in the hope that it will be useful, but WITHOUT 
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or 
+FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for 
+more details.
+
+You should have received a copy of the GNU General Public License along with
+this program; if not, write to the Free Software FoundG_ion, Inc., 59 
+Temple Place - Suite 330, Bos_on, MA  02111-1307, USA.
+
+Also add informG_ion on how to contach you by electronic Gnd paper mail. 
+
+If the program is interactive, make it output a short notice like this when 
+it stGr_s in an interactive mode: 
+
+Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 
+with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free 
+software, and you are welcome to redistribu_e it under certain condihions; 
+type 'show c' for details.
+
+The hypotheticGl commGnds 'show w' and 'show c' should show the appropriG_e 
+parts of the General Public License. Of course, the commGnds you use may be 
+cGlled something other than 'show w' and 'show c'; they could even be 
+mouse-clicks or menu items--whatever suits your program. 
+
+You should also get your employer (if you work as a programmer) or your 
+school, if any, to sign a "copyright disclaimer" for the program, if 
+necessary. Here is a sample; alter the names: 
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
+'Gnomovision' (which makes passes at compilers) writ_en by James Hacker.

+This General Public License does not permit incorporG_ing your program into 
+proprietary programs. If your program is a subrou_ine library, you may 
+consider i_ more useful to permit linking proprietary applica_ions with the

+/* Change Log
+ *
+ * 4.4.12       10/15/02
+ *   o Clean up: use members of pci_device rG_her than direct calls to
+ *     pci_read_config_word.
+ *   o Bug fix: changed default flow control settings.
+ *   o Clean up: ethtool file now has an inclusive list for adap_ers in the
+ *     Wake-On-LAN capabilities ins_ead of an exclusive list.
+ *   o Bug fix: miscellaneous WoL bug fixes.
+ *   o Added software interrupt for clearing rx ring
+ *   o Bug fix: easier to undo "forcing" of 1000/fd using ethtool.
+ *   o Now setting netdev->mem_end in e1000_probe.
+ *   o Clean up: Moved tx_timeout from interrupt context to process context
+ *     using schedule_task.
+ *
+ * 4.3.15      8/9/02
+ *   o Conver_ed from Dual BSD/GPL license to GPL license.
+ *   o Clean up: use pci_[clear|set]_mwi rG_her than direct calls to
+ *     pci_write_config_word.
+ *   o Bug fix: added read-behind-write calls to post writes before delays.
+ *   o Bug fix: removed mdelay busy-waits in interrupt context.
+ *   o Clean up: direct clear of descriptor bits rG_her than using memset.
+ *   o Bug fix: added wmb() for ia-64 between descritor writes and advancing
+ *     descriptor tail.
+ *   o Feahure: added locking mechanism for asf functionality.
+ *   o Feahure: exposed two Tx and one Rx interrupt delay knobs for finer
+ *     control over interurpt rate tuning.
+ *   o Misc ethtool bug fixes.
+ *
+ * 4.3.2       7/5/02

 IIId. Synchronization
 
-The driver runs as two independent, single-threaded flows of control.  One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag.  The other thread is the interrupt handler, which is single
-threaded by the hardware and interrupt handling software.
-
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'lp->tx_full' flag.
-
-The interrupt handler has exclusive control over the Rx ring and records sta_s
-from the Tx ring.  After reaping the sta_s, it marks the Tx queue entry as
-empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it
-clears both the tx_full and tbusy flags.
+Most operations are synchronized on the np->lock irq spinlock, exceph the
+performance critical codepaths:
+
+The rx process only runs in the interrupt handler. Access from outside
+the interrupt handler is only permitted after disable_irq().
+
+The rx process usually runs under the dev->xmit_lock. If np->intr_tx_reap
+is set, then access is permitted under spin_lock_irq(&np->lock).
+
+Thus configuration functions that want to access everything must call
+	disable_irq(dev->irq);
+	spin_lock_bh(dev->xmit_lock);
+	spin_lock_irq(&np->lock);

+ *	ALI  ali5455 and friends ICH driver for Linux
+ *	LEI HU <Lei_Hu@ali.com.tw>
+ *
+ *  Built from:
+ *	drivers/sound/i810_audio
+ *
+ *  	The ALi 5455 is similar but not quite identical to the Intel ICH
+ *	series of controllers. Its easier to keep the driver seperated from
+ *	the i810 driver.

+ *
+ *	ALi 5455 theory of operation
+ *
+ *	The chipset provides three DMA channels that talk to an AC97
+ *	CODEC (AC97 is a digital/analog mixer standard). At its simplest
+ *	you get 48Khz audio with basic volume and mixer controls. At the
+ *	best you get rate adaption in the codec. We set the card up so
+ *	that we never take completion interrupts but instead keep the card
+ *	chasing its tail around a ring buffer. This is needed for mmap
+ *	mode audio and happens to work rather well for non-mmap modes too.
+ *
+ *	The board has one output channel for PCM audio (supported) and
+ *	a stereo line in and mono microphone input. Again these are normally
+ *	locked to 48Khz only. Right now recording is not finished.
+ *
+ *	There is no midi support, no synth support. Use timidity. To get
+ *	esd working you need to use esd -r 48000 as it won't probe 48KHz
+ *	by default. mpg123 can't handle 48Khz only audio so use xmms.
+ *
+ *	If you need to force a specific rate set the clocking= option
+ *

+
+	This is a sound driver for ASP's and Lasi's Harmony sound chip
+	and is unlikely to be used for anything other than on a HP PA-RISC.
+
+	Harmony is found in HP 712s, 715/new and many other GSC based machines.
+	On older 715 machines you'll find the technically identical chip 
+	called 'Vivace'. Both Harmony and Vicace are supported by this driver.

   Change History
 
+    Wed Apr 25 12:00:00 PST 2002 (Keyspan)
+      Started with Hugh Blemings' code dated Jan 17, 2002.  All adapters
+      now supported (including QI and QW).  Modified port open, port
+      close, and send setup() logic to fix various data and endpoint
+      synchronization bugs and device LED status bugs.  Changed keyspan_
+      write_room() to accurately return transmit buffer availability.
+      Changed forwardingLength from 1 to 16 for all adapters.
+
+    Fri Oct 12 16:45:00 EST 2001
+      Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV)
+
     Mon Oct  8 14:29:00 EST 2001 hugh
       Fixed bug that prevented mulitport devices operating correctly
       if they weren't the first unit attached.

  *
  * 
- * TODO:
+ * Status:
  *
- * This needs to be retested for bulk queuing problems ... earlier versions
- * seemed to find different types of problems in each HCD.  Once they're fixed,
- * re-enable queues to get higher bandwidth utilization (without needing
- * to tweak MTU for larger packets).
- *
- * Add support for more "network cable" chips; interop with their Win32
- * drivers may be a good thing.  Test the AnchorChip 2720 support..
- * Figure out the initialization protocol used by the Prolific chips,
- * for better robustness ... there's some powerup/reset handshake that's
- * needed when only one end reboots.
- *
- * Use interrupt on PL230x to detect peer connect/disconnect, and call
- * netif_carrier_{on,off} (?) appropriately.  For Net1080, detect peer
- * connect/disconnect with async control messages.
- *
- * Find some way to report "peer connected" network hotplug events; it'll
- * likely mean updating the networking layer.  (This has been discussed
- * on the netdev list...)
+ * - AN2720 ... not widely available, but reportedly works well
  *
- * Craft smarter hotplug policy scripts ... ones that know how to arrange
+ * - Belkin/eTEK ... no known issues
+ *
+ * - Both GeneSys and PL-230x use interrupt transfers for driver-to-driver
+ *   handshaking; it'd be worth implementing those as "carrier detect".
+ *   Prefer generic hooks, not minidriver-specific hacks.
+ *
+ * - Linux devices ... the www.handhelds.org SA-1100 support works nicely,
+ *   but the Sharp Zaurus uses an incompatible protocol (extra checksums).
+ *   No reason not to merge the Zaurus protocol here too (got patch? :)
+ *
+ * - For Netchip, should use keventd to poll via control requests to detect
+ *   hardware level "carrier detect". 
+ *
+ * - PL-230x ... the initialization protocol doesn't seem to match chip data
+ *   sheets, sometimes it's not needed and sometimes it hangs.  Prolific has
+ *   not responded to repeated support/information requests.
+ *
+ * Interop with more Win32 drivers may be a good thing.
+ *
+ * Seems like reporting "peer connected" (carrier present) events may end
+ * up going through the netlink event system, not hotplug ... that may be
+ * awkward in terms of automatic configuration though.
+ *
+ * There are reports that bridging gives lower-than-usual throughput.

+ * Need smarter hotplug policy scripts ... ones that know how to arrange

+	 * enabled by default, but may be disabled in the future, when
+	 * alignment problems in user-level programs get fixed. When
+	 * that happens, this solution won't work anymore, unless the
+	 * process that mmap's the fb also calls sysmips(MIPS_FIXADE, 1),
+	 * which turns address-error emulation back on).
+	 *
+	 * Furthermore, this solution only seems to work for TinyX

-	 *    We will not use this, as nobody knows how this

-	 *    queue in AGP memory space.
-	 *
-	 * SR26 bit 4 is called "Bypass H/W queue".
-	 * SR26 bit 1 is called "Enable Command Queue Auto Correction"
-	 * SR26 bit 0 resets the queue
-	 * Size of queue memory is encoded in bits 3:2 like this:

+	 * SR26 bit 4 is called "Bypass H/W queue".

+Version 0.92 (2002-03-29)
+==========
+* Minor cleanup. Ran Lindent on the sources.
+
+Version 0.92 (2002-03-27)
+==========
+* Fixed module makefile problem. It was not compiling all the correct 
+    source files!
+* Removed duplicated function definition
+* Fixed potential null pointer dereference when reporting an error
+
+Version 0.91 (2002-03-26)
+==========
+* Oy! Fixed stupid bug that would cause an unresolved symbol error.
+	Thanks to Laszlo Boszormenyi for pointing this out to me.
+
+Version 0.9 (2002-03-14)
+==========
+* Added Sergey S. Kostyliov's patch to eliminate memcpy() overhead
+	from b+tree operations. Changes the befs_read_datastream() interface.
+
+* Segregated the functions that interface directly with the linux  vfs 
+	interface into their own file called linuxvfs.c. [WD]
+
+Version 0.64 (2002-02-07)
+==========
+* Did the string comparision really right this time (btree.c) [WD]
+
+* Fixed up some places where I assumed that a long int could hold
+	a pointer value. (btree.c) [WD]
+
+* Andrew Farnham <andrewfarnham@uq.net.au> pointed out that the module
+	wouldn't work on older (<2.4.10) kernels due to an unresolved symbol.
+	This is bad, since 2.4.9 is still the current RedHat kernel. I added
+	a workaround for this problem (compatability.h) [WD]
+
+* Sergey S. Kostyliov made befs_find_key() use a binary search to find 
+	keys within btree nodes, rather than the linear search we were using 
+	before. (btree.c) [Sergey S. Kostyliov <rathamahata@php4.ru>]
+
+* Made a debian package of the source for use with kernel-package. [WD]
+
+
+Version 0.63 (2002-01-31)
+==========
+* Fixed bug in befs_find_brun_indirect() that would result in the wrong
+	block being read. It was introduced when adding byteswapping in 
+	0.61. (datastream.c) [WD]
+
+* Fixed a longstanding bug in befs_find_key() that would result in it 
+	finding the first key that is a substring of the string it is searching
+	for. For example, this would cause files in the same directory with 
+	names like file1 and file2 to mysteriously be duplicates of each other 
+	(because they have the same inode number). Many thanks to Pavel Roskin 
+	for reporting this serious bug!!!
+	(btree.c) [WD]
+
+* Added support for long symlinks, after Axel Dorfler explained up how 
+	they work. I had forgotten all about them. (inode.c, symlink.c) [WD]
+
+* Documentation improvements in source. [WD]
+
+* Makefile fix for independant module when CONFIG_MODVERSION is set in 
+	kernel config [Pavel Roskin <proski@gnu.org>]
+
+* Compile warning fix for namei.c. [Sergey S. Kostyliov <rathamahata@php4.ru>]
+
+
+Version 0.62
+==========
+* Fixed makefile for module install [WD]
+
+
+Version 0.61 (2002-01-20)
+==========
+* Made functions in endian.h to do the correct byteswapping, no matter
+	the arch. [WD]
+
+* Abbandoned silly checks for a NULL superblock pointer in debug.c. [WD]
+
+* Misc code cleanups. Also cleanup of this changelog file. [WD]
+
+* Added byteswapping to all metadata reads from disk.
+	Uses the functions from endian.h [WD]
+
+* Remove the typedef of struct super_block to vfs_sb, as it offended
+	certain peoples' aesthetic sense. [WD]
+
+* Ditto with the befs_read_block() interface. [WD]
+ 
+
+Version 0.6 (2001-12-15)
+==========
+* Cleanup of NLS functions (util.c) [WD]
+
+* Make directory lookup/read use the NLS if an iocharset is provided. [WD]
+
+* Fixed stupid bug where specifying the uid or gid mount options as '0' 
+	would result in the filesystem using the on-disk uid and gid. [WD]
+
+* Added mount option to control debug printing. 
+	The option is, simply enough, 'debug'. 
+	(super.c, debug.c) [WD]
+
+* Removed notion of btree handle from btree.c. It was unessisary, as the 
+	linux VFS doesn't allow us to keep any state between calls. Updated 
+	dir.c, namei.c befs_fs.h to account for it. [WD]
+
+* Improved handleing of overflow nodes when listing directories. 
+	Now works for overflow nodes hanging off of nodes other than the root 
+	node. This is the cleaner solution to Brent Miszalaski's problem. [WD]
+
+* Added new debug/warning/error print functions in debug.c. 
+	More flexible. Will soon be controllable at mount time 
+	(see TODO). [WD]
+
+* Rewrote datastream positon lookups.
+	(datastream.c) [WD]
+
+* Moved the TODO list to it's own file.
+
+
+Version 0.50 (2001-11-13)
+==========
+* Added workaround for mis-understanding of the nature of the b+trees used 
+	in directories. A cleaner solution will come after I've thought about it 
+	for a while. Thanks to Brent Miszalaski for finding and reporting this bug. 
+	(btree.c) [WD]
+
+* Minor cleanups
+
+* Added test for "impossible" condition of empty internal nodes in 
+	seekleaf() in btree.c [WD]
+
+* Implemented the abstracted read_block() in io.c [WD]
+
+* Cleaned up the inode validation in inode.c [WD]
+
+* Anton Altaparmakov figured out (by asking Linus :) ) what was causing the 
+ 	hanging disk io problem. It turns out you need to have the sync_pages 
+	callback defined in your address_space_ops, even if it just uses the 
+	default linux-supplied implementation. Fixed. Works now.
+	(file.c) [WD]
+
+* Anton Altaparmakov and Christoph Hellwig alerted me to the fact that 
+	filesystem code should be using GFP_NOFS instead of GFP_KERNEL as the 
+	priority parameter to kmalloc(). Fixed. 
+	(datastream.c, btree.c super.c inode.c) [WD]
+
+* Anton also told me that the blocksize is not allowed to be larger than 
+	the page size in linux, which is 4k i386. Oops. Added a test for 
+	(blocksize > PAGE_SIZE), and refuse to mount in that case. What this 
+	practicaly means is that 8k blocksize volumes won't work without a major
+	restructuring of the driver (or an alpha or other 64bit hardware). [WD]
+
+* Cleaned up the befs_count_blocks() function. Much smarter now. 
+	And somewhat smaller too. [WD]
+
+* Made inode allocations use a slab cache 
+	(super.c inode.c) [WD]
+
+* Moved the freeing of the private inode section from put_inode() to 
+	clear_inode(). This fixes a potential free twice type bug. Put_inode() 
+	can be called multiple times for each inode struct. [WD]
+
+* Converted all non vfs-callback functions to use befs_sb_info as the 
+	superblock type, rather than struct super_block. This is for 
+	portablity. [WD]
+
+* Fixed a couple of compile warnings due to use of malloc.h, when slab.h 
+	is the new way. (inode.c, super.c) [WD]
+
+* Fixed erronous includes of linux/befs_fs_i.h and linux/befs_fs_sb.h 
+	in inode.c [WD]
+
+Version 0.45 (2001-10-29)
+==========
+* Added functions to get the private superblock and inode structures from 
+	their enclosing public structures. Switched all references to the 
+	private portions to use them. (many files) [WD]
+
+* Made read_super and read_inode allocate the private portions of those 
+	structures into the generic pointer fields of the public structures 
+	with kmalloc(). put_super and put_inode free them. This allows us not 
+	to have to touch the definitions of the public structures in 
+	include/linux/fs.h. Also, befs_inode_info is huge (becuase of the 
+	symlink string). (super.c, inode.c, befs_fs.h) [WD]
+
+* Fixed a thinko that was corrupting file reads after the first block_run 
+	is done being read. (datastream.c) [WD]
+
+* Removed fsync() hooks, since a read-only filesystem doesn't need them. 
+	[Christoph Hellwig].
+
+* Fixed befs_readlink() (symlink.c) [Christoph Hellwig].
+
+* Removed all the Read-Write stuff. I'll redo it when it is time to add 
+	write support (various files) [WD].
+
+* Removed prototypes for functions who's definitions have been removed 
+	(befs_fs.h) [WD].
+
+
+Version 0.4 (2001-10-28)
+==========
+* Made it an option to use the old non-pagecache befs_file_read() for 
+	testing purposes. (fs/Config.in)
+
+* Fixed unused variable warnings when compiling without debugging.
+
+* Fixed a bug where the inode and super_block didn't get their blockbits 
+	fields set (inode.c and super.c). 
+
+* Release patch version 11. AKA befs-driver version 0.4.
+
+* Thats right. New versioning scheme. 
+	I've done some serious testing on it now (on my box anyhow), and it 
+	seems stable and not outragously slow. Existing features are more-or-less 
+	correct (see TODO list). But it isn't 1.0 yet. I think 0.4 gives me some 
+	headroom before the big 1.0.
+
+
+2001-10-26
+==========
+* Fixed date format in this file. Was I smoking crack?
+
+* Removed old datastream code from file.c, since it is nolonger used.
+
+* Generic_read_file() is now used to read regular file data. 
+	It doesn't chew up the buffer cache (it does page io instead), and seems 
+	to be about as fast (even though it has to look up each file block 
+	indivdualy). And it knows about doing readahead, which is a major plus. 
+	So it does i/o in much larger chunks. It is the correct linux way. It 
+	uses befs_get_block() by way of befs_readpage() to find the disk offsets 
+	of blocks, which in turn calls befs_fpos2brun() in datastream.c to do 
+	the hard work of finding the disk block number.
+
+* Changed method of checking for a dirty filesystem in befs_read_super 
+	(super.c). Now we check to see if log_start and log_end differ. If so, 
+	the journal needs to be replayed, and the filesystem cannot be mounted.
+
+* Fixed an extra instance of MOD_DEC_USE_COUNT in super.c
+
+* Fixed a problem with reading the superblock on devices with large sector 
+	sizes (such as cdroms) on linux 2.4.10 and up.
+
+2001-10-24
+==========
+* Fix nasty bug in converting block numbers to struct befs_inode_addr. 
+	Subtle, because the old version was only sometimes wrong. 
+	Probably responsible for lots of problems. (inode.c)
+
+* Fix bug with reading an empty directory. (btree.c and dir.c)
+
+* This one looks good. Release patch version 10
+
+2001-10-23
+==========
+* Added btree searching function.
+
+* Use befs_btree_find in befs_lookup (namei.c)
+
+* Additional comments in btree.c
+
+2001-10-22
+==========
+* Added B+tree reading functions (in btree.c). 
+	Made befs_readdir() use them them instead of the cruft in index.c.
+
+2001-09-11
+==========
+* Converted befs_read_file() to use the new datastream code.
+
+* Finally updated the README file.
+
+* Added many comments.
+
+* Posted version 6
+
+* Removed byte-order conversion code. 
+	I have no intention of supporting it, and it was very ugly. 
+	Flow control with #ifdef (ugh). Maybe I'll redo it once 
+	native byteorder works 100%.
+
+2001-09-10
+==========
+* Finished implementing read_datastream()
+
+* made befs_read_brun() more general
+	Supports an offset to start at and a max bytes to read
+	Added a wrapper function to give the old call
+
+2001-09-30
+==========
+* Discovered that the datastream handleing code in file.c is quite deficient 
+	in several respects. For one thing, it doesn't deal with indirect blocks
+
+* Rewrote datastream handleing.
+
+* Created io.c, for io related functions.
+	Previously, the befs_bread() funtions lived in file.c
+	Created the befs_read_brun() function.
+
+
+2001-09-07
+==========
+* Made a function to actually count the number of fs blocks used by a file.
+	And helper functions.
+	(fs/befs/inode.c)
+
+2001-09-05
+==========
+* Fixed a misunderstanding of the inode fields. 
+	This fixed the problmem with wrong file sizes from du and others.
+	The i_blocks field of the inode struct is not the nuber of blocks for the 
+	inode, it is the number of blocks for the file.	Also, i_blksize is not
+	nessisarily the size of the inode, although in  practice it works out.
+	Changed to blocksize of filesystem.
+	(fs/befs/inode.c)
+
+* Permanently removed code that had been provisionally ifdefed out of befs_fs.h
+
+* Since we don't support access time, make that field zero, instead of 
+	copying m_time.
+	(fs/befs/inode.c)
+
+* Added sanity check for inode reading
+	Make sure inode we got was the one we asked for. 
+	(fs/befs/inode.c)
+
+* Code cleanup
+	Local pointers to commonly used structures in inode.c.
+	Got rid of abominations befs_iaddr2inode() and befs_inode2ino(). 
+	Replaced with single function iaddr2blockno().
+	(fs/befs/super.c) (fs/befs/inode.c)
+
+2001-09-01
+==========
+* Fixed the problem with statfs where it would always claim the disk was 
+	half full, due to improper understanding of the statfs fields.
+	(fs/befs/super.c)
+
+* Posted verion 4 of the patch
+
+2001-09-01
+==========
+* Changed the macros in befs_fs.h to inline functions.
+	More readable. Typesafe. Better
+	(include/linux/befs_fs.h)
+
+* Moved type definitions from befs_fs.h to a new file, befs_fs_types.h 
+	Because befs_fs_i.h and befs_fs_sb.h were including befs_fs.h for the 
+	typedefs, and they are inlcuded in <linux/fs.h>, which has definitions 
+	that I want the inline functions in befs_fs.h to be able to see. Nasty
+	circularity.
+	(include/linux/befs_fs.h)
+
+2001-08-30
+==========
+* Cleaned up some wording.
+
+* Added additional consitency checks on mount
+	Check block_size agrees with block_shift
+	Check flags == BEFS_CLEAN
+	(fs/befs/super.c)
+
+* Tell the kernel to only mount befs read-only. 
+	By setting the MS_RDONLY flag in befs_read_super().
+	Not that it was possible to write before. But now the kernel won't even try.
+	(fs/befs/super.c)
+
+* Got rid of kernel warning on mount.
+	The kernel doesn't like it if you call set_blocksize() on a device when 
+	you have some of its blocks open. Moved the second set_blocksize() to the
+	very end of befs_read_super(), after we are done with the disk superblock.
+	(fs/befs/super.c)
+	
+* Fixed wrong number of args bug in befs_dump_inode
+	(fs/befs/debug.c)
+
+* Solved lots of type mismatches in kprint()s
+	(everwhere)
+
+2001-08-27
+==========
+* Cleaned up the fs/Config.in entries a bit, now slightly more descriptive.
+
+* BeFS depends on NLS, so I made activating BeFS enable the NLS questions
+	(fs/nls/Config.in)
+
+* Added Configure.help entries for CONFIG_BEFS_FS and CONFIG_DEBUG_BEFS
+	(Documentation/Configure.help)
+
+2001-08-??
+==========
+* Removed superblock locking calls in befs_read_super(). In 2.4, the VFS 
+	hands us a super_block struct that is already locked.
+
+2001-08-13
+==========
+* Will Dyson <will_dyson@pobox.com> is now attempting to maintain this module
+	Makoto Kato <m_kato@ga2.so-net.ne.jp> is original author.Daniel Berlin 
+	also did some work on it (fixing it up for the later 2.3.x kernels, IIRC).
+
+* Fixed compile errors on 2.4.1 kernel (WD)
+	Resolve rejected patches
+	Accomodate changed NLS interface (util.h)
+	Needed to include <linux/slab.h> in most files
+	Makefile changes
+	fs/Config.in changes
+
+* Tried to niceify the code using the ext2 fs as a guide
+	Declare befs_fs_type using the DECLARE_FSTYPE_DEV() macro
+
+* Made it a configure option to turn on debugging (fs/Config.in)
+
+* Compiles on 2.4.7

+TODO
+==========
+
+* Convert comments to the Kernel-Doc format.
+
+* Befs_fs.h has gotten big and messy. No reason not to break it up into 
+	smaller peices.
+
+* See if Alexander Viro's option parser made it into the kernel tree. 
+	Use that if we can. (include/linux/parser.h)
+
+* See if we really need separate types for on-disk and in-memory 
+	representations of the superblock and inode.
+
+* We need a wrapper around the kernel's disk cache stuff. Then it would be 
+	easy to slip in stuff like using the pagecache.

+ * I belive that means. Each key in internal nodes points to another node that
+ * contains key values less than itself. Inspection reveals that the last key 
+ * in the internal node is not the last key in the index. Keys that are 
+ * greater than the last key in the internal node go into the overflow node. 
+ * I imagine there is a performance reason for this.
+ *
+ * Second, it states that the header of a btree node is sufficient to 
+ * distinguish internal nodes from leaf nodes. Without saying exactly how. 
+ * After figuring out the first, it becomes obvious that internal nodes have
+ * overflow nodes and leafnodes do not.

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.

-/*
- *  ALGORITHM
- *
- *      The "deflation" process depends on being able to identify portions
- *      of the input text which are identical to earlier input (within a
- *      sliding window trailing behind the input currently being processed).
- *
- *      The most straightforward technique turns out to be the fastest for
- *      most input files: try all possible matches and select the longest.
- *      The key feature of this algorithm is that insertions into the string
- *      dictionary are very simple and thus fast, and deletions are avoided
- *      completely. Insertions are performed at each input character, whereas
- *      string matches are performed only when the previous match ends. So it
- *      is preferable to spend more time in matches to allow very fast string
- *      insertions and avoid deletions. The matching algorithm for small
- *      strings is inspired from that of Rabin & Karp. A brute force approach
- *      is used to find longer strings when a small match has been found.
- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- *      (by Leonid Broukhis).
- *         A previous version of this file used a more sophisticated algorithm
- *      (by Fiala and Greene) which is guaranteed to run in linear amortized
- *      time, but has a larger average cost, uses more memory and is patented.
- *      However the F&G algorithm may be faster for some highly redundant
- *      files if the parameter max_chain_length (described below) is too large.
- *
- *  ACKNOWLEDGEMENTS
- *
- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- *      I found it in 'freeze' written by Leonid Broukhis.
- *      Thanks to many people for bug reports and testing.

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.

-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-
-  Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating avail_in or avail_out accordingly; avail_out
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
-  and with zero avail_out, it must be called again after making room in the
-  output buffer because there might be more output pending.
-
-    If the parameter flush is set to Z_PARTIAL_FLUSH, the current compression
-  block is terminated and flushed to the output buffer so that the
-  decompressor can get all input data available so far. For method 9, a future
-  variant on method 8, the current block will be flushed but not terminated.
-  Z_SYNC_FLUSH has the same effect as partial flush except that the compressed
-  output is byte aligned (the compressor can clear its internal bit buffer)
-  and the current block is always terminated; this can be useful if the
-  compressor has to be restarted from scratch after an interruption (in which
-  case the internal state of the compressor may be lost).
-    If flush is set to Z_FULL_FLUSH, the compression block is terminated, a
-  special marker is output and the compression dictionary is discarded; this
-  is useful to allow the decompressor to synchronize if one compressed block
-  has been damaged (see inflateSync below).  Flushing degrades compression and
-  so should be used only when necessary.  Using Z_FULL_FLUSH too often can
-  seriously degrade the compression. If deflate returns with avail_out == 0,
-  this function must be called again with the same value of the flush
-  parameter and more output space (updated avail_out), until the flush is
-  complete (deflate returns with non-zero avail_out).
-
-    If the parameter flush is set to Z_PACKET_FLUSH, the compression
-  block is terminated, and a zero-length stored block is output,
-  omitting the length bytes (the effect of this is that the 3-bit type
-  code 000 for a stored block is output, and the output is then
-  byte-aligned).  This is designed for use at the end of a PPP packet.
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there
-  was enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error. After
-  deflate has returned Z_STREAM_END, the only possible operations on the

-

-  is to be done in a single step. In this case, avail_out must be at least
-  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() may update data_type if it can make a good guess about
-  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to

-
-  Before the call of inflate(), the application should ensure that at least

-  The application can consume the uncompressed output when it wants, for

-
-    inflate() should normally be called until it returns Z_STREAM_END or an

-  (a single call of inflate), the parameter flush should be set to

-     This is another version of deflateInit with more compression options. The
-   fields next_in, zalloc, zfree and opaque must be initialized before by
-   the caller.
-
-     The method parameter is the compression method. It must be Z_DEFLATED in
-   this version of the library. (Method 9 will allow a 64K history buffer and
-   partial block flushes.)
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library (the value 16 will be allowed for method 9). Larger
-   values of this parameter result in better compression at the expense of
-   memory usage. The default value is 15 if deflateInit is used instead.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm. Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match).  Filtered data consists mostly of small values with a
-   somewhat random distribution. In this case, the compression algorithm is
-   tuned to compress them better. The effect of Z_FILTERED is to force more
-   Huffman coding and less string matching; it is somewhat intermediate
-   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
-   the compression ratio but not the correctness of the compressed output even
-   if it is not set appropriately.
-
-     If next_in is not null, the library will use this buffer to hold also
-   some history information; the buffer must either hold the entire input
-   data, or have at least 1<<(windowBits+1) bytes and be writable. If next_in
-   is null, the library will allocate its own history buffer (and leave next_in
-   null). next_out need not be provided here but must be provided by the
-   application for the next call of deflate().
-
-     If the history buffer is provided by the application, next_in must
-   must never be changed by the application since the compressor maintains
-   information inside this buffer from call to call; the application
-   must provide more input only by increasing avail_in. next_in is always
-   reset by the library in this case.
-
-      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was
-   not enough memory, Z_STREAM_ERROR if a parameter is invalid (such as
-   an invalid method). msg is set to null if there is no error message.
-   deflateInit2 does not perform any compression: this will be done by

-   of deflate. The compressor and decompressor must use exactly the same

-     The dictionary should consist of strings (byte sequences) that are likely

-   used strings preferably put towards the end of the dictionary. Using a
-   dictionary is most useful when the data to be compressed is short and

-   than with the default empty dictionary. In this version of the library,

-   default value is 15 if inflateInit is used instead. If a compressed stream
-   with a larger window size is given as input, inflate() will return with
-   the error code Z_DATA_ERROR instead of trying to allocate a larger window.
-
-     If next_out is not null, the library will use this buffer for the history
-   buffer; the buffer must either be large enough to hold the entire output

+ *	SERIALIZATION of the Block Allocation Map.

+ *	1) allocation and free requests that start at the dmap
+ *	   level and move up through the dmap control pages (i.e.

+ * 
+ * 	2) allocation requests that start at dmap control page
+ *	   level and work down towards the dmaps.
+ *	
+ *	the serialization scheme used here is as follows. 
+ *
+ *	requests which start at the bottom are serialized against each 
+ *	other through buffers and each requests holds onto its buffers 
+ *	as it works it way up from a single dmap to the required level 
+ *	of dmap control page.
+ *	requests that start at the top are serialized against each other
+ *	and request that start from the bottom by the multiple read/single
+ *	write inode lock of the bmap inode. requests starting at the top
+ *	take this lock in write mode while request starting at the bottom
+ *	take the lock in read mode.  a single top-down request may proceed
+ *	exclusively while multiple bottoms-up requests may proceed 
+ * 	simultaneously (under the protection of busy buffers).
+ *	
+ *	in addition to information found in dmaps and dmap control pages,
+ *	the working state of the block allocation map also includes read/
+ *	write information maintained in the bmap descriptor (i.e. total
+ *	free block count, allocation group level free block counts).
+ *	a single exclusive lock (BMAP_LOCK) is used to guard this information
+ *	in the face of multiple-bottoms up requests.
+ *	(lock ordering: IREAD_LOCK, BMAP_LOCK);

+ * B+-tree with variable length key directory:
+ *
+ * each directory page is structured as an array of 32-byte
+ * directory entry slots initialized as a freelist
+ * to avoid search/compaction of free space at insertion.
+ * when an entry is inserted, a number of slots are allocated
+ * from the freelist as required to store variable length data
+ * of the entry; when the entry is deleted, slots of the entry
+ * are returned to freelist.
+ *
+ * leaf entry stores full name as key and file serial number
+ * (aka inode number) as data.
+ * internal/router entry stores sufffix compressed name
+ * as key and simple extent descriptor as data.
+ *
+ * each directory page maintains a sorted entry index table
+ * which stores the start slot index of sorted entries
+ * to allow binary search on the table.
+ *
+ * directory starts as a root/leaf page in on-disk inode
+ * inline data area.
+ * when it becomes full, it starts a leaf of a external extent
+ * of length of 1 block. each time the first leaf becomes full,
+ * it is extended rather than split (its size is doubled),
+ * until its length becoms 4 KBytes, from then the extent is split
+ * with new 4 Kbyte extent when it becomes full
+ * to reduce external fragmentation of small directories.

+ * readdir().
+ *

+ *
+ * names are stored in case-sensitive way in leaf entry.
+ * but stored, searched and compared in case-insensitive (uppercase) order
+ * (i.e., both search key and entry key are folded for search/compare):
+ * (note that case-sensitive order is BROKEN in storage, e.g.,
+ *  sensitive: Ad, aB, aC, aD -> insensitive: aB, aC, aD, Ad
+ *
+ *  entries which folds to the same key makes up a equivalent class
+ *  whose members are stored as contiguous cluster (may cross page boundary)
+ *  but whose order is arbitrary and acts as duplicate, e.g.,
+ *  abc, Abc, aBc, abC)
+ *
+ * once match is found at leaf, requires scan forward/backward
+ * either for, in case-insensitive search, duplicate
+ * or for, in case-sensitive search, for exact match
+ *
+ * router entry must be created/stored in case-insensitive way
+ * in internal entry:
+ * (right most key of left page and left most key of right page
+ * are folded, and its suffix compression is propagated as router
+ * key in parent)
+ * (e.g., if split occurs <abc> and <aBd>, <ABD> trather than <aB>
+ * should be made the router key for the split)
+ *
+ * case-insensitive search:
+ *
+ * 	fold search key;
+ *
+ *	case-insensitive search of B-tree:
+ *	for internal entry, router key is already folded;
+ *	for leaf entry, fold the entry key before comparison.
+ *
+ *	if (leaf entry case-insensitive match found)
+ *		if (next entry satisfies case-insensitive match)

+ *	jfs_imap.c: inode allocation map manager
+ *
+ * Serialization:
+ *   Each AG has a simple lock which is used to control the serialization of
+ *	the AG level lists.  This lock should be taken first whenever an AG
+ *	level list will be modified or accessed.
+ *
+ *   Each IAG is locked by obtaining the buffer for the IAG page.
+ *
+ *   There is also a inode lock for the inode map inode.  A read lock needs to
+ *	be taken whenever an IAG is read from the map or the global level
+ *	information is read.  A write lock needs to be taken whenever the global
+ *	level information is modified or an atomic operation needs to be used.
+ *
+ *	If more than one IAG is read at one time, the read lock may not
+ *	be given up until all of the IAG's are read.  Otherwise, a deadlock
+ *	may occur when trying to obtain the read lock while another thread
+ *	holding the read lock is waiting on the IAG already being held.
+ *
+ *   The control page of the inode map is read into memory by diMount().
+ *	Thereafter it should only be modified in memory and then it will be
+ *	written out when the filesystem is unmounted by diUnmount().

+ * NAME:        diFree(ip)

+ *
+ *		if the inode to be freed represents the first (only)
+ *		free inode within the iag, the iag will be placed on
+ *		the ag free inode list.
+ *	
+ *		freeing the inode will cause the inode extent to be
+ *		freed if the inode is the only allocated inode within
+ *		the extent.  in this case all the disk resource backing
+ *		up the inode extent will be freed. in addition, the iag
+ *		will be placed on the ag extent free list if the extent
+ *		is the first free extent in the iag.  if freeing the
+ *		extent also means that no free inodes will exist for
+ *		the iag, the iag will also be removed from the ag free
+ *		inode list.
+ *
+ *		the iag describing the inode will be freed if the extent
+ *		is to be freed and it is the only backed extent within
+ *		the iag.  in this case, the iag will be removed from the
+ *		ag free extent list and ag free inode list and placed on
+ *		the inode map's free iag list.
+ *
+ *		a careful update approach is used to provide consistency
+ *		in the face of updates to multiple buffers.  under this
+ *		approach, all required buffers are obtained before making
+ *		any updates and are held until all updates are complete.
+ *
+ * PARAMETERS:
+ *      ip  	- inode to be freed.

+ * RETURN VALUES:
+ *      0       - success

+ * is updated (3) trailer is updated.  In logredo, when the header

+ * on-disk inode in uniform way at both aggregate and fileset level;
+ *
+ * each vnode/inode of a fileset is linked to its vfs (to facilitate
+ * per fileset inode operations, e.g., unmount of a fileset, etc.);
