 This is possible with the DAC interfaces purely because they are
 not translated in any way.
 
+		Optimizing Unmap State Space Consumption
+
+On many platforms, pci_unmap_{single,page}() is simply a nop.
+Therefore, keeping track of the mapping address and length is a waste
+of space.  Instead of filling your drivers up with ifdefs and the like
+to "work around" this (which would defeat the whole purpose of a
+portable API) the following facilities are provided.
+
+Actually, instead of describing the macros one by one, we'll
+transform some example code.
+
+1) Use DECLARE_PCI_UNMAP_{ADDR,LEN} in state saving structures.
+   Example, before:
+
+	struct ring_state {
+		struct sk_buff *skb;
+		dma_addr_t mapping;
+		__u32 len;
+	};
+
+   after:
+
+	struct ring_state {
+		struct sk_buff *skb;
+		DECLARE_PCI_UNMAP_ADDR(mapping)
+		DECLARE_PCI_UNMAP_LEN(len)
+	};
+
+   NOTE: DO NOT put a semicolon at the end of the DECLARE_*()
+         macro.
+
+2) Use pci_unmap_{addr,len}_set to set these values.
+   Example, before:
+
+	ringp->mapping = FOO;
+	ringp->len = BAR;
+
+   after:
+
+	pci_unmap_addr_set(ringp, mapping, FOO);
+	pci_unmap_len_set(ringp, len, BAR);
+
+3) Use pci_unmap_{addr,len} to access these values.
+   Example, before:
+
+	pci_unmap_single(pdev, ringp->mapping, ringp->len,
+			 PCI_DMA_FROMDEVICE);
+
+   after:
+
+	pci_unmap_single(pdev,
+			 pci_unmap_addr(ringp, mapping),
+			 pci_unmap_len(ringp, len),
+			 PCI_DMA_FROMDEVICE);
+
+It really should be self-explanatory.  We treat the ADDR and LEN
+seperately, because it is possible for an implementation to only
+need the address in order to perform the unmap operation.
+
+			Platform Issues
+
+If you are just writing drivers for Linux and do not maintain
+an architecture port for the kernel, you can safely skip down
+to "Closing".
+
+1) Struct scatterlist requirements.
+
+   Struct scatterlist must contain, at a minimum, the following
+   members:
+
+	char *address;
+	struct page *page;
+	unsigned int offset;
+	unsigned int length;
+
+   The "address" member will disappear in 2.5.x
+
+   This means that your pci_{map,unmap}_sg() and all other
+   interfaces dealing with scatterlists must be able to cope
+   properly with page being non NULL.
+
+   A scatterlist is in one of two states.  The base address is
+   either specified by "address" or by a "page+offset" pair.
+   If "address" is NULL, then "page+offset" is being used.
+   If "page" is NULL, then "address" is being used.
+
+   In 2.5.x, all scatterlists will use "page+offset".  But during
+   2.4.x we still have to support the old method.
+
+2) More to come...

+Tridentfb is a framebuffer driver for some Trident chip based cards.
+
+The following list of chips is thought to be supported although not all are
+tested:
+
+those from the Image series with Cyber in their names - accelerated
+those with Blade in their names (Blade3D,CyberBlade...) - accelerated
+the newer CyberBladeXP family  - nonaccelerated
+
+Only PCI/AGP based cards are supported, none of the older Tridents.
+
+How to use it?
+==============
+Just do your usual console work :)
+
+When booting you can pass the following parameters
+==================================================
+
+noaccel - turns off acceleration (when it doesn't work for your card)
+accel - force text acceleration (for boards which by default are noacceled)
+
+fp	- use flat panel related stuff
+crt 	- assume monitor is present instead of fp
+
+center 	- for flat panels and resolutions smaller than native size center the
+	  image, otherwise use
+stretch
+
+memsize - integer value in Kb, use if your card's memory size is misdetected.
+	  look at the driver output to see what it says when initializing.
+memdiff - integer value in Kb,should be nonzero if your card reports
+	  more memory than it actually has.For instance mine is 192K less than
+	  detection says in all three BIOS selectable situations 2M, 4M, 8M.
+	  Only use if your video memory is taken from main memory hence of
+	  configurable size.Otherwise use memsize.
+	  If in some modes which barely fit the memory you see garbage at the bottom
+	  this might help by not letting change to that mode anymore.
+
+nativex - the width in pixels of the flat panel.If you know it (usually 1024
+	  800 or 1280) and it is not what the driver seems to detect use it.
+
+bpp  - bits per pixel (8,16 or 32)
+mode - a mode name like 800x600 (as described in Documentation/fb/modedb.txt)
+
+Using insane values for the above parameters will probably result in driver
+misbehaviour so take care(for instance memsize=12345678 or memdiff=23784 or
+nativex=93)

+Strange kernel messages
+
+You may see devfs-related messages in your kernel logs. Below are some
+messages and what they mean (and what you should do about them, if
+anything).
+
+
+
+devfs_register(fred): could not append to parent, err: -17
+
+You need to check what the error code means, but usually 17 means
+EEXIST. This means that a driver attempted to create an entry
+fred in a directory, but there already was an entry with that
+name. This is often caused by flawed boot scripts which untar a bunch
+of inodes into /dev, as a way to restore permissions. This
+message is harmless, as the device nodes will still
+provide access to the driver (unless you use the devfs=only
+boot option, which is only for dedicated souls:-). If you want to get
+rid of these annoying messages, upgrade to devfsd-v1.3.20 and use the
+recommended RESTORE directive to restore permissions.
+
+
+devfs_mk_dir(bill): using old entry in dir: c1808724 ""
+
+This is similar to the message above, except that a driver attempted
+to create a directory named bill, and the parent directory
+has an entry with the same name. In this case, to ensure that drivers
+continue to work properly, the old entry is re-used and given to the
+driver. In 2.5 kernels, the driver is given a NULL entry, and thus,
+under rare circumstances, may not create the require device nodes.
+The solution is the same as above.
+
+
+
+
+
+Compilation problems with devfsd
+
+Usually, you can compile devfsd just by typing in
+make in the source directory, followed by a make
+install (as root). Sometimes, you may have problems, particularly
+on broken configurations.
+
+
+
+error messages relating to DEVFSD_NOTIFY_DELETE
+
+This happened because you have an ancient set of kernel headers
+installed in /usr/include/linux or /usr/src/linux.
+Install kernel 2.4.10 or later. You may need to pass the
+KERNEL_DIR variable to make (if you did not install
+the new kernel sources as /usr/src/linux), or you may copy
+the devfs_fs.h file in the kernel source tree into
+/usr/include/linux.

 Introduction
 ============
 The SCSI Generic driver (sg) is one of the four "high level" SCSI device
 drivers along with sd, st and sr (disk, tape and CDROM respectively). Sg
 is more generalized (but lower level) than its siblings and tends to be
 used on SCSI devices that don't fit into the already serviced categories.
-Thus sg is used for scanners, cd writers and reading audio cds digitally
+Thus sg is used for scanners, CD writers and reading audio CDs digitally
 amongst other things.
 
-These are notes on the Linux SCSI generic packet device driver (sg)
-describing version 2.1.39 . The original driver was written by Lawrence
-Foard and remained in place with minimal changes since circa 1992.
-Version 2 of this driver remains backward compatible (binary and
-source **) with the original. It adds scatter gather, command queuing,
-per file descriptor sequencing, asynchronous notification and better
-error reporting.
-
-This is an abridged version of the sg documentation that is targeted
-at the linux/Documentation directory. The full document can be found
-at http://www.torque.net/sg/p/scsi-generic_long.txt .
-
-The Linux 2.4 series kernels have now been released. Lk 2.4 contains
-an upgraded "version 3" sg driver which is described in a supplementary
-document at http://www.torque.net/sg/p/scsi-generic_v3.txt .
-
-The interface and usage of the original sg driver have been documented
-by Heiko Eissfeldt in a HOWTO called SCSI-Programming-HOWTO. My copy
-of the document is version 1.5 dated 7th May 1996. It can found at
-ftp://sunsite.unc.edu/pub/Linux/docs/HOWTO-SCSI-Programming-HOWTO .
-A copy of this document can be found at:

-
-** It is possible to write applications that perform differently
-depending on whether they are using the original or this version of
-the sg device driver. The author is not aware of any useful
-pre-existing applications that have problems with version 2.
-
-
-Architecture
-============
-The SCSI generic packet device driver (sg) is a character based device.
-It is one of the four high level device driver in the SCSI sub-system;
-the others are sd (for direct-access devices - disks), st (for tapes)
-and sr (for data cdroms). Sd and sr are block devices while st (like sg)
-is a character device.
-
-The unifying layer of the SCSI sub-system is the so-called mid-level.
-Below that are the "low level" drivers which are the drivers for the
-various adapters supported by Linux. Also at this level are pseudo
-adapter drivers such as ide-scsi which converts the SCSI protocol to
-ATAPI (which are similar to one another) for use by IDE devices.
-
-Since sg is a character device it supports the traditional Unix
-system calls of open(), close(), read(), write() and ioctl(). Two other
-related system calls: poll() and fcntl() are added to this list and
-how they interact with the sg device driver is documented later.
-
-An SG device is accessed by write()ing SCSI commands plus any associated
-outgoing data to it; the resulting status codes and any incoming data are
-then obtained by a read() call. The device can be opened O_NONBLOCK
-(non-blocking) and poll() used to monitor its progress. The device may be
-opened O_EXCL which excludes other "sg" users from this device (but not
-"sd", "st" or "sr" users). The buffer given to the write() call is made
-up as follows:
-        - struct sg_header image (see below)
-        - scsi command (6, 10 or 12 bytes long)
-        - data to be written to the device (if any)
-
-The buffer received from the corresponding read() call contains:
-        - struct sg_header image (check status/errors + sense_buffer)
-        - data read back from device (if any)
-
-The given SCSI command has its LUN field overwritten by the LUN value of
-the associated sg device that has been open()ed.
-
-SCSI commands are only attempted once (i.e. there are no internal
-retries). If appropriate (e.g. a SCSI READ) the data buffer is copied back
-to user space irrespective of the values of the various SCSI related
-error/status codes. [Some adapters that use an old error interface in
-the SCSI mid level ignore the retry count and retry certain errors.]
-
-
-sg_header
-=========
-This is the name of the control structure that conveys information
-about the length of data to be read/written by the associated SCSI
-command. It also conveys error and status information from the
-read() call. An instance of this structure is the first thing that
-is placed in the data buffers of both write() and read().
-
-In its original form it looked like this:
-struct sg_header {
-    int pack_len;
-    int reply_len;
-    int pack_id;
-    int result;
-    unsigned int twelve_byte:1;
-    unsigned int other_flags:31;
-    unsigned char sense_buffer[16];
-}; /* this structure is 36 bytes long */
-
-The 'pack_len' is bizarre and ends up having the 'reply_len' put in it
-(perhaps it had a use at some stage). Even though it looks like an
-input variable, it is not read by sg internally (only written).
-
-The 'reply_len' is the length of the data the corresponding read()
-will/should request (including the sg_header).
-
-The 'pack_id' is not acted upon by the sg device driver but is conveyed
-back to the corresponding read() so it can be used for sequencing by an
-application.
-
-The 'result' is also bizarre, turning certain types of host codes to 0 (no
-error), EBUSY or EIO. With better error reporting now available, the
-'result' is best ignored.
-
-The 'twelve_byte' field overrides the internal SCSI command length detection
-algorithm for group 6 and 7 commands (ie when 1st byte >= 0xc0) and forces
-a command length of 12 bytes.
-The command length detection algorithm is as follows:
-Group:  0    1    2    3    4    5    6    7
-Length: 6   10   10   12   12   12   10   10
-
-'other_flags' was originally documented as "not used" but some current
-applications assume it has 0 placed in it.
-
-The 'sense_buffer' is the first 16 bytes of SCSI sense buffer that is
-returned when the target returns a SCSI status code of CHECK_CONDITION
-or COMMAND_TERMINATED [or (driver_status & DRIVER_SENSE) is true]. This
-buffer should be at least 18 bytes long and arguably 32 bytes; unfortunately
-this is unlikely to happen in the 2.2.x series of kernels.
-
-
-The new sg_header offered in this driver is:
-#define SG_MAX_SENSE 16
-struct sg_header
-{
-    int pack_len;    /* [o] reply_len (ie useless) ignored as input */
-    int reply_len;   /* [i] max length of expected reply (inc. sg_header) */
-    int pack_id;     /* [io] id number of packet (use ints >= 0) */
-    int result;      /* [o] 0==ok, else (+ve) Unix errno (best ignored) */
-    unsigned int twelve_byte:1;
-        /* [i] Force 12 byte command length for group 6 & 7 commands  */
-    unsigned int target_status:5;   /* [o] scsi status from target */
-    unsigned int host_status:8;     /* [o] host status (see "DID" codes) */
-    unsigned int driver_status:8;   /* [o] driver status+suggestion */
-    unsigned int other_flags:10;    /* unused */
-    unsigned char sense_buffer[SG_MAX_SENSE]; /* [o] Output in 3 cases:
-           when target_status is CHECK_CONDITION or
-           when target_status is COMMAND_TERMINATED or
-           when (driver_status & DRIVER_SENSE) is true. */
-};      /* This structure is 36 bytes long on i386 */
-
-Firstly the new header is binary compatible with the original. This is
-important for keeping existing apps working without recompilation.
-
-Only those elements (or fields) that are new or in some way different
-from the original are documented below.
-
-'pack_id' becomes input to a read() when ioctl(sg_fd, SG_SET_FORCE_PACK_ID,
-&one) is active. A 'pack_id' of -1 is interpreted as fetch the oldest
-waiting packet; any other value will cause the read() to wait (or yield
-EAGAIN) until a packet with that 'pack_id' becomes available. In all cases
-the value of 'pack_id' available after a read() is the value given to that
-variable in the prior, corresponding write().
-
-The SCSI command length can now be given directly using the SG_NEXT_CMD_LEN
-ioctl().
-
-The 'target_status' field is always output and is the (masked and shifted
-1 bit right) SCSI status code from the target device. The allowable
-values are (found in <scsi/scsi.h>):
-/* N.B. 1 bit offset from usual SCSI status values */
-#define GOOD                 0x00
-#define CHECK_CONDITION      0x01
-#define CONDITION_GOOD       0x02
-#define BUSY                 0x04
-#define INTERMEDIATE_GOOD    0x08

-#define RESERVATION_CONFLICT 0x0c
-#define COMMAND_TERMINATED   0x11
-#define QUEUE_FULL           0x14
-When the 'target_status' is CHECK_CONDITION or COMMAND_TERMINATED the
-'sense_buffer' is output. Note that when (driver_status & DRIVER_SENSE)
-is true then the 'sense_buffer' is also output (this seems to occur when
-the ide-scsi emulation is used). When the 'sense_buffer' is output the
-SCSI Sense Key can be found at (sense_buffer[2] & 0x0f) .
-
-The 'host_status' field is always output and has the following values
-whose "defines" are not visible outside the kernel. A copy of these
-defines can be found in sg_err.h (see the utilities section):
-#define DID_OK          0x00 /* NO error                                */
-#define DID_NO_CONNECT  0x01 /* Couldn't connect before timeout period  */
-#define DID_BUS_BUSY    0x02 /* BUS stayed busy through time out period */
-#define DID_TIME_OUT    0x03 /* TIMED OUT for other reason              */
-#define DID_BAD_TARGET  0x04 /* BAD target, device not responding?      */
-#define DID_ABORT       0x05 /* Told to abort for some other reason     */
-#define DID_PARITY      0x06 /* Parity error                            */
-#define DID_ERROR       0x07 /* Internal error [DMA underrun on aic7xxx]*/
-#define DID_RESET       0x08 /* Reset by somebody.                      */
-#define DID_BAD_INTR    0x09 /* Got an interrupt we weren't expecting.  */
-#define DID_PASSTHROUGH 0x0a /* Force command past mid-layer            */
-#define DID_SOFT_ERROR  0x0b /* The low level driver wants a retry      */
-
-The 'driver_status' field is always output. When ('driver_status' &
-DRIVER_SENSE) is true the 'sense_buffer' is also output. A copy of these
-defines can be found in sg_err.h (see the utilities section):
-#define DRIVER_OK           0x00 /* Typically no suggestion */
-#define DRIVER_BUSY         0x01
-#define DRIVER_SOFT         0x02
-#define DRIVER_MEDIA        0x03
-#define DRIVER_ERROR        0x04
-#define DRIVER_INVALID      0x05
-#define DRIVER_TIMEOUT      0x06
-#define DRIVER_HARD         0x07
-#define DRIVER_SENSE        0x08 /* Implies sense_buffer output */
-/* above status 'or'ed with one of the following suggestions */
-#define SUGGEST_RETRY       0x10
-#define SUGGEST_ABORT       0x20
-#define SUGGEST_REMAP       0x30
-#define SUGGEST_DIE         0x40
-#define SUGGEST_SENSE       0x80
-
-'other_flags' still remains as a 10 bit field (reduced from 31 bits), so
-code that places 0 in it will still be happy. It is not used.
-
-
-System Calls
-============
-What follows are descriptions of the characteristics of the standard
-Unix operating system calls when applied to a SCSI generic device
-using this version of the device driver.
-
-open(const char * filename, int flags)
---------------------------------------
-The filename should be an 'sg' device such as
-/dev/sg[0,1,2,...]
-/dev/sg[a-z]             <<< now deprecated >>>
-or a symbolic link to one of these. [Devfs has its own sub-directory for
-sg devices with entries like: /dev/scsi/host1/bus2/target3/lun4/generic .]
-It seems as though SCSI devices are allocated to sg minor numbers in the
-same order as they appear in 'cat /proc/scsi/scsi'. Sg is a "character"
-based Linux device driver.  This means it has an open/close/read/write/ioctl
-type interface.
-
-Flags can be either O_RDONLY or O_RDWR or-ed with either
-O_EXCL          waits for other opens on sg device to be closed before
-                proceeding. If O_NONBLOCK is set then yields EBUSY when
-                someone else has the sg device open. The combination of
-                O_RDONLY and O_EXCL is disallowed.
-O_NONBLOCK      Sets non-blocking mode. Calls that would otherwise block
-                yield EAGAIN (eg read() ) or EBUSY (eg open() ).
-
-The original version of sg did not allow the O_RDONLY (yielding a EACCES
-error). This version allows it for accessing ioctls (e.g. doing an sg
-device scan with the SG_GET_SCSI_ID ioctl) but write()s will not be
-allowed. These flags are found in <fcntl.h> .
-
-By default, sequencing is per file descriptor in this version of sg. This
-means, for example that 2 processes can independently manipulate the same
-sg device at the same time. This may or may not make sense depending on
-the application: 2 processes (logically) reading from the same direct access
-device (ie a disk) is ok while running 2 instances of cd writing software
-on the same device at the same time probably wouldn't be a good idea. The
-previous version of sg supported only per device sequencing and this can
-still be selected with the SG_SET_MERGE_FD,1 ioctl().
-
-The driver will attempt to reserve SG_DEF_RESERVED_SIZE bytes (32KBytes in
-the current sg.h) on open(). The size of this reserved buffer can
-subsequently be modified with the SG_SET_RESERVED_SIZE ioctl(). In both
-cases these are requests subject to various dynamic constraints. The actual
-amount of memory obtained can be found by the SG_GET_RESERVED_SIZE ioctl().
-The reserved buffer will be used if:
-    -  it is not already in use (eg when command queuing is in use)
-    -  a write() does not call for a buffer size larger than the
-       reserved size.
-
-Returns a file descriptor if >= 0 , otherwise -1 implies an error.
-
-Error codes (value in 'errno' after -1 returned):
-EACCES          Either the user doesn't have appropriate permissions on
-                'filename' or attempted to use both O_RDONLY and O_EXCL
-EBUSY           O_NONBLOCK set and some user of this sg device has O_EXCL
-                set while someone is already using this device
-EINTR           while waiting for an "exclusive" lock to clear, a signal
-                is received, just try again ...
-ENODEV          sg not compiled into kernel or the kernel cannot find the

-ENOENT          given filename not found
-ENOMEM          An attempt to get memory to store this open's context
-                failed (this was _not_ a request to reserve DMA memory)
-ENXIO           either there is no attached device corresponding to given

-
-write(int sg_fd, const void * buffer, size_t count)
----------------------------------------------------
-Even though sg is a character-based device driver it sends and receives
-packets to/from the associated scsi device. Write() is used to send a
-packet containing 2 mandatory parts and 1 optional part. The mandatory
-parts are:
-  - a control block (an instance of struct sg_header)
-  - a SCSI command (6, 10 or 12 bytes long)
-The optional part is:
-  - outgoing data (eg if a SCSI write command is being sent)
-These should appear as one contiguous string in the buffer given to
-write() in the above order with no pad characters.
-
-If a write() accepts this packet then at some later time the user should
-call a read() to get the result of the SCSI command. The previous sg
-driver enforced a strict write()/read()/write()/read() regime so that a
-second write() would block until first read() was finished. This sg
-driver relaxes that condition and thereby allows command queuing
-(limit is SG_MAX_QUEUE (16) outstanding packets per file descriptor).
-However, for backward compatibility, command queuing is turned off
-by default (#define SG_DEF_COMMAND_Q 0 in sg.h). This can be changed
-via the SG_SET_COMMAND_Q ioctl() [or by recompiling after changing
-the above define to 1].
-
-In this sg driver a write() should return more or less immediately.
-
-Returns number of bytes written if > 0 , otherwise -1 implies an error.
-
-Error codes (value in 'errno' after -1 returned):
-EACCES          opened with RD_ONLY flag
-EAGAIN          SCSI mid-level out of command blocks (rare), try again.
-                This is more likely to happen when queuing commands,
-                so wait a bit (eg usleep(10000) ) before trying again
-EDOM            a) command queuing off: a packet is already queued
-                b) command queuing on: too many packets queued
-                   (SG_MAX_QUEUE exceeded)
-EFAULT          'buffer' for 'count' bytes is an invalid memory range
-EIO             a) incoming buffer too short. It should be at least
-                   (6 + sizeof(struct sg_header))==42 bytes long
-                b) SCSI command length given in SG_NEXT_CMD_LEN too long
-                c) reply_len negative
-ENOMEM          can't get memory for DMA. Take evasive action ...
-ENXIO           either scsi sub-system is currently processing some error
-                (eg doing a device reset) or the sg driver/module removed
-                or corrupted
-
-
-read(int sg_fd, void * buffer, size_t count)
---------------------------------------------
-Read() is used to receive a packet containing 1 mandatory part and 1
-optional part. The mandatory part is:
-  - a control block (an instance of struct sg_header)
-The optional part is:
-  - incoming data (eg if a SCSI read command was sent by earlier write() )
-The buffer given to a read() and its corresponding count should be
-sufficient to accommodate this packet to avoid truncation. Truncation occurs
-if count < sg_header::replylen .
-
-By default, read() will return the oldest packet queued up. If the
-SG_SET_FORCE_PACK_ID,1 ioctl() is active then read() will attempt to
-fetch the packet whose pack_id (given earlier to write()) matches the
-sg_header::pack_id given to this read(). If not available it will either
-wait or yield EAGAIN. As a special case, -1 in sg_header::pack_id given
-to read() will match the oldest packet.
-
-Returns number of bytes read if > 0 , otherwise -1 implies an error.
-Unfortunately the return value in the non-error case is simply the
-same as the count argument. It is not the actual number of bytes
-DMA-ed by the SCSI device. This driver is currently unable to provide
-such an underrun indication.
-
-If the SCSI device reports an error then a REQUEST SENSE is automatically
-done and the output is placed in the sense_buffer array which is in the
-control block. This action is sometimes called "auto-sense".
-
-Error codes (value in 'errno' after -1 returned):
-EAGAIN          either no waiting packet or requested packet is not
-                available while O_NONBLOCK flag was set
-EFAULT          'buffer' for 'count' bytes is an invalid memory range
-EINTR           while waiting for a packet, a signal is received, just
-                try again ...
-EIO             if the 'count' given to read() is < sizeof(struct sg_header)
-                and the 'result' element in sg_header is non-zero. Not a
-                recommended error reporting technique
-ENXIO           either scsi sub-system is currently processing some error
-                (eg doing a device reset) or the sg driver/module removed
-                or corrupted
-
-
-close(int sg_fd)
-----------------
-Preferably a close() should be done after all issued write()s have had
-their corresponding read() calls completed. Unfortunately this is not
-always possible. The semantics of close() in Unix are to return more
-or less immediately (ie not wait on any event) so the driver needs to
-arrange for an orderly cleanup of those packets that are still "in
-flight".
-
-A process that has an open file descriptor to an sg device may be aborted
-(eg by a kill signal). In this case, the kernel automatically calls close
-(which is called 'sg_release()' in the version 2 driver) to facilitate
-the cleanup mentioned above.
-
-A problem persists in version 2.1.39 if the sg driver is a module and is
-removed while packets are still "in flight".
-
-Returns 0 if successful, otherwise -1 implies an error.
-
-Error codes (value in 'errno' after -1 returned):
-ENXIO           sg driver/module removed or corrupted
-
-ioctl(int sg_fd, int command, ...)  [sg specific]
--------------------------------------------------
-Ken Thompson (or perhaps some other Unix luminary) described ioctl() as
-the "garbage bin of Unix". This driver compounds the situation by adding
-more ...
-If a ioctl command is not recognized by sg (and the various lower levels
-that it may pass the command on to) then the error EINVAL occurs. If an
-invalid address is given (in the 3rd argument) then the error EFAULT occurs.
-
-Those commands with an appended "+" are new in version 2.
-
-Those commands with an appended "W" are only accessible from file
-descriptors opened with O_RDWR. They will yield EACCES otherwise.
-
-SG_GET_TIMEOUT:
-Ignores its 3rd argument and _returns_ the timeout value (which will be
->= 0 ). The unit of this timeout is "jiffies" which are currently 10
-millisecond intervals on i386 (less on an alpha). Linux supplies
-a manifest constant HZ which is the number of "jiffies" in 1 second.
-
-SG_SET_TIMEOUT:
-Assumes 3rd argument points to an int containing the new timeout value
-for this file descriptor. The unit is a "jiffy". Packets that are
-already "in flight" will not be affected. The default value is set
-on open() and is SG_DEFAULT_TIMEOUT (defined in sg.h). This default is
-currently 1 minute and may not be long enough for formats. Negative
-values will yield an EIO error.
-
-SG_EMULATED_HOST:
-Assumes 3rd argument points to an int and outputs a flag indicating
-whether the host (adapter) is connected to a real SCSI bus or is an
-emulated one (eg ide-scsi device driver). A value of 1 means emulated
-while 0 is not.
-
-SG_SET_TRANSFORM  W:
-Only is meaningful when SG_EMULATED host has yielded 1 (i.e. the low-level
-is the ide-scsi device driver); otherwise an EINVAL error occurs. The
-default state is to _not_ transform SCSI commands to the corresponding
-ATAPI commands but pass them straight through as is. [Only certain classes
-of SCSI commands need to be transformed to their ATAPI equivalents.]
-The third argument is interpreted as an integer. When it is non-zero then
-a flag is set inside the ide-scsi driver that transforms subsequent
-commands sent to this driver. When zero is passed as the 3rd argument to
-this ioctl then the flag within the ide-scsi driver is cleared and
-subsequent commands are not transformed. Beware, this state will affect
-all devices (and hence all related sg file descriptors) associated with
-this ide-scsi "bus".
-
-SG_GET_TRANSFORM:
-Third argument is ignored. Only is meaningful when SG_EMULATED host has
-yielded 1 (ie the low-level is the ide-scsi device driver); otherwise
-an EINVAL error occurs. Returns 0 to indicate _not_ transforming SCSI
-to ATAPI commands (default). Returns 1 when it is transforming them.
-
-SG_SET_FORCE_LOW_DMA +:
-Assumes 3rd argument points to an int containing 0 or 1. 0 (default)
-means sg decides whether to use memory above 16 Mbyte level (on i386)
-based on the host adapter being used by this SCSI device. Typically
-PCI SCSI adapters will indicate they can DMA to the whole 32 bit address
-space.
-If 1 is given then the host adapter is overridden and only memory below
-the 16MB level is used for DMA. A requirement for this should be
-extremely rare. If the "reserved" buffer allocated on open() is not in
-use then it will be de-allocated and re-allocated under the 16MB level
-(and the latter operation could fail yielding ENOMEM).
-Only the current file descriptor is affected.
-
-SG_GET_LOW_DMA +:
-Assumes 3rd argument points to an int and places 0 or 1 in it. 0
-indicates the whole 32 bit address space is being used for DMA transfers
-on this file descriptor. 1 indicates the memory below the 16MB level
-(on i386) is being used (and this may be the case because the host
-adapters setting has been overridden by SG_SET_FORCE_LOW_DMA,1 .
-
-SG_GET_SCSI_ID +:
-Assumes 3rd argument is pointing to an object of type Sg_scsi_id (see
-sg.h) and populates it. That structure contains ints for host_no,
-channel, scsi_id, lun, scsi_type, allowable commands per lun and
-queue_depth. Most of this information is available from other sources
-(eg SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER) but tends to be
-awkward to collect.
-Allowable commands per lun and queue_depth give an insight to the
-command queuing capabilities of the adapters and the device. The latter
-overrides the former (logically) and the former is only of interest
-if it is equal to queue_depth which probably indicates the device
-does not support queueing commands (e.g. most scanners).
-
-SG_SET_FORCE_PACK_ID +:
-Assumes 3rd argument is pointing to an int. 0 (default) instructs read()
-to return the oldest (written) packet if multiple packets are
-waiting to be read (when command queuing is being used).
-1 instructs read() to view the sg_header::pack_id as input and return the
-oldest packet matching that pack_id or wait until it arrives (or yield
-EAGAIN if O_NONBLOCK is in force). As a special case the pack_id of -1
-given to read() in the mode will match the oldest packet.
-Only the current file descriptor is affected by this command.
-
-SG_GET_PACK_ID +:
-Assumes 3rd argument points to an int and places the pack_id of the
-oldest (written) packet in it. If no packet is waiting to be read then
-yields -1.
-
-SG_GET_NUM_WAITING +:
-Assumes 3rd argument points to an int and places the number of packets
-waiting to be read in it.
-
-SG_GET_SG_TABLESIZE +:
-Assumes 3rd argument points to an int and places the maximum number of
-scatter gather elements supported by the host adapter. 0 indicates that
-the adapter does support scatter gather.
-
-SG_SET_RESERVED_SIZE +W:
-Assumes 3rd argument is pointing to an int. That value will be used to
-request a new reserved buffer of that size. The previous reserved buffer
-is freed (if it is not in use; if it was in use -EBUSY is returned).
-A new reserved buffer is then allocated and its actual size can be found by
-calling the SG_GET_RESERVED_SIZE ioctl(). The reserved buffer is then used
-for DMA purposes by subsequent write() commands if it is not already in
-use and if the write() is not calling for a buffer size larger than that
-reserved. The reserved buffer may well be a series of kernel buffers if the
-adapter supports scatter-gather. Large buffers can be requested (eg 1 MB).
-
-SG_GET_RESERVED_SIZE +:
-Assumes 3rd argument points to an int and places the size in bytes of
-the reserved buffer from open() or the most recent SG_SET_RESERVED_SIZE
-ioctl() call on this fd.  The result can be 0 if memory is very tight. In
-this case it may not be wise to attempt something like burning a CD on
-this file descriptor.
-
-SG_SET_MERGE_FD +W:
-Assumes 3rd argument is pointing to an int. 0 (the default) causes all
-subsequent sequencing to be per file descriptor. 1 causes all subsequent
-sequencing to be per device. If this command tries to change the current
-state and there is one or more _other_ file descriptors using this sg
-device then an EBUSY error occurs. Per device sequencing was the original
-semantics and allowed, for example different processes to "share" the
-device, one perhaps write()ing with the other one read()ing. This command
-is supplied if anyone needs those semantics. Per file descriptor
-sequencing, perhaps with the use of the O_EXCL flag, seems more sensible.
-
-SG_GET_MERGE_FD +:
-Assumes 3rd argument points to an int and places 0 or 1 in it. 0 implies
-sequencing is per file descriptor. 1 implies sequencing is per device
-(original sg driver's semantics).
-
-SG_SET_COMMAND_Q +:
-Assumes 3rd argument is pointing to an int. 0 (current default, set by
-SG_DEF_COMMAND_Q in sg.h) disables command queuing. Attempts to write()
-a packet while one is already queued will result in a EDOM error.
-1 turns command queuing on.
-Changing the queuing state only affects write()s done after the change.
-Only the current file descriptor is affected by this command.
-
-SG_GET_COMMAND_Q +:
-Assumes 3rd argument points to an int and places 0 or 1 in it. 0 implies
-that command queuing is off on this file descriptor. 1 implies command
-queuing is on.
-
-SG_SET_UNDERRUN_FLAG +:
-Assumes 3rd argument is pointing to an int. 0 (current default, set by
-SG_DEF_UNDERRUN_FLAG in sg.h) requests underruns be ignored. 1 requests
-that underruns be flagged. [The only low level driver that acts on this
-at the moment is the aic7xxx which yields a DID_ERROR error on underrun.]
-Only the current file descriptor is affected by this command (unless
-"per device" sequencing has been selected).
-
-SG_GET_UNDERRUN_FLAG +:
-Assumes 3rd argument points to an int and places 0 or 1 in it. 0 implies
-that underruns are not being reported. 1 implies that underruns are being
-reported (see SG_SET_UNDERRUN_FLAG for more details).
-
-SG_NEXT_CMD_LEN +:
-Assumes 3rd argument is pointing to an int. The value of the int (if > 0)
-will be used as the SCSI command length of the next SCSI command sent to
-a write() on this fd. After that write() the SCSI command length logic is
-reset to use automatic length detection (ie depending on SCSI command group
-and the 'twelve_byte' field). If the current SCSI command length maximum of
-12 is exceeded then the affected write() will yield an EDOM error.
-Giving this ioctl() a value of 0 will set automatic length detection for
-the next write(). N.B. Only the following write() on this fd is affected by
-this ioctl().
-
-SG_GET_VERSION_NUM +:
-Assumes 3rd argument points to an int. The version number is then placed
-in that int. A sg version such as 2.1.36 will yield "20136" from this ioctl.
-
-SG_SCSI_RESET +:
-Assumes 3rd argument points to an int. Unfortunately doesn't currently
-do much (may in the future after other issues are resolved). Yields an
-EBUSY error if the SCSI bus or the associated device is being reset
-when this ioctl() is called, otherwise returns 0.
-N.B. In some recent distributions there is a patch to the SCSI mid level
-code that activates this ioctl. Check your distribution.
-
-SG_SET_DEBUG +:
-Assumes 3rd argument is pointing to an int. 0 (default) turns debugging
-off. Values > 0 cause the SCSI sense buffer to be decoded and output
-to the console/log when a SCSI device error occurs. Values > 8 cause
-the current sg device driver's state to be output to the console/log
-(this is a "one off" effect).
-If you need a _lot_ of the SCSI sub-system debug information (mainly from
-the mid-level) then try 'echo "scsi dump 0" > /proc/scsi/scsi' and lots of
-debug will appear in your console/log.
-
-
-poll(struct pollfd * udfds, unsigned int nfds, int timeout_ms)
---------------------------------------------------------------
-This is a native call in Linux 2.2 but most of its capabilities are available
-through the older select() call. Given a choice poll() should probably be
-used. Typically poll() is used when a sg scsi device is open()ed O_NONBLOCK
-for polling; and optionally with asynchronous notification as well using
-the fcntl() system call (below) and the SIGPOLL (aka SIGIO) signal.
-Only if something drastically is wrong (eg file handle gone stale) will
-POLLERR ever be set. POLLPRI, POLLHUP and POLLNVAL are never set.
-POLLIN is set when there is one or more packets waiting to be read.
-When POLLIN is set it implies that a read() will not block (nor yield
-EAGAIN in non-blocking mode) but return a packet immediately.
-POLLOUT (aka POLLWRNORM) is set when write() is able to accept a packet
-(ie will _not_ yield an EDOM error). The setting of POLLOUT is affected
-by the SG_SET_COMMAND_Q state: if the state is on then POLLOUT will remain
-set until the number of queued packets reaches SG_MAX_QUEUE, if the
-state is off then POLLOUT is only set when no packets are queued.
-Note that a packet can be queued after write()ing but not available to be
-read(); this typically happens when a SCSI read command is issued while
-the data is being retrieved.
-Poll() is per file descriptor unless SG_SET_MERGE_FD is set in which case
-it is per device.
-
-
-fcntl(int sg_fd, int cmd) or fcntl(int sg_fd, int cmd, long arg)
-----------------------------------------------------------------
-There are several uses for this system call in association with a sg
-file descriptor. The following pseudo code shows code that is useful for
-scanning the sg devices, taking care not to be caught in a wait for
-an O_EXCL lock by another process, and when the appropriate device is
-found, switching to normal blocked io. A working example of this logic
-is in the sg_scan utility program.
-
-open("/dev/sg0", O_RDONLY | O_NONBLOCK)
-/* check device, EBUSY means some other process has O_EXCL lock on it */
-/* when the device you want is found then ... */
-flags = fcntl(sg_fd, F_GETFL)
-fcntl(sg_fd, F_SETFL, flags & (~ O_NONBLOCK))
-/* since, for simple apps, it is easier to use normal blocked io */
-
-
-Some work has to be done in Linux to set up for asynchronous notification.
-This is a non-blocking mode of operation in which, when the driver receives
-data back from a device so that a read() can be done, it sends a SIGPOLL
-(aka SIGIO) signal to the owning process. A working example of this logic
-is in the sg_poll test program.
-
-sigemptyset(&sig_set)
-sigaddset(&sig_set, SIGPOLL)
-sigaction(SIGPOLL, &s_action, 0)
-fcntl(sg_fd, F_SETOWN, getpid())
-flags = fcntl(sg_fd, F_GETFL);
-fcntl(sg_fd, F_SETFL, flags | O_ASYNC)
-
-
-Utility and Test Programs
-=========================
-See the README file in the sg_utils<date>.tgz tarball. Look on the
-http://www.torque.net/sg website for the latest version.
-
-Briefly, that tarball contains the following utilities:
-sg_dd512        'dd' like program that assumes 512 byte blocks size
-sg_dd2048       'dd' like program that assumes 2048 byte blocks size
-sg_dd2352       'dd' like program that assumes 2352 byte blocks size
-sgq_dd512       like 'sg_dd512' but does command queuing on "if"
-sgp_dd          probably the most flexible 'dd' variant. It uses POSIX
-                threads, block size set by "bs=..." plus other options.
-sg_scan         outputs information (optionally Inquiry) on SCSI devices
-sg_rbuf         tests SCSI bus transfer speed (without physical IO)
-sg_whoami       outputs info (optionally capacity) of given SCSI device
-sginfo          outputs "mode" information about SCSI devices (it is a
-                  re-port of the scsiinfo program onto the sg interface)
-
-It also contains the following test programs:
-sg_debug        outputs sg driver state to console/log file
-sg_poll         tests asynchronous notification
-sg_runt_ex      example run time selection program for application authors
-sg_simple1      example program first time users
-sg_simple2      like sg_simple1 but with more primitive error processing
-sg_inquiry      does a SCSI Inquiry command (from original HOWTO)
-sg_tst_med      checks presence of media (from original HOWTO)
-
-There are also 2 source files (sg_err.[hc]) for outputting and categorizing
-SCSI 2 errors and warnings. This code is used by most of the above
-utility and test programs.
-
-The following programs: sg_dd512, sg_dd2048, sg_dd2352, sg_scan, sg_runt_ex,
-sg_rbuf, sg_tst_med, sg_inquiry and sginfo, can be compiled either for this
-new sg driver _or_ the original sg driver (in 2.0 or 2.2 series kernels).
-sg_runt_ex can be run on 2.0, 2.2 or 2.3 series kernels even if it is
-compiled on a different series (eg compiled on 2.0, run on 2.2).
-
-
-Header files
-============
-User applications need to find the correct "sg.h" header file matching
-their kernel in order to write code using the sg device driver. This is
-sometimes more difficult than it should be. The correct "sg.h" will usually
-be found at /usr/src/linux/include/scsi/sg.h . Another important header
-file is "scsi.h" which will be in the same directory.
-
-When "#include <scsi/sg.h>" is written in an application then this refers
-to the file /usr/include/scsi/sg.h . A problem sometimes arises because
-the files in the /usr/include/scsi directory are controlled by the GNU
-library people who maintain glibc. Unfortunately these 2 versions of
-the sg.h header file are not always in sync. [This was the case in Redhat
-6.0 and 6.1 .] Glibc 2.1.3 and later versions should get this right.
-
-If this is a problem, the user may need to copy sg.h (and scsi.h) from
-the kernel source includes to /usr/include scsi. If the user can change
-the effected source code then another approach is to rely on the fact that
-/usr/src/linux is a symbolic link to /usr/src/linux/include/linux and
-change the sg.h include to look like:
-    #include <linux/../scsi/sg.h>
-This solution is used by the author of cdparanoia (Monty) in his application.
-
-[Former scsi generic documents suggested adding a symbolic link to
-bypass this problem but that is not popular with the glibc maintainers.
-I would like to thank Andreas Jaeger <aj@suse.de> for his contributions
-on this subject.]

-Conclusion
-==========
-The SCSI generic packet device driver attempts to make as few assumptions
-as possible about the device it is connected to while giving applications
-using it as much flexibility as possible on the SCSI command level. Sg
-needs to hide the "messy" kernel related details while protecting
-the integrity of the kernel against sg "abuse". Some of these aims are
-contradictory and some compromises need to be made. For example: should
-a sg based application be able to reset a SCSI bus when that could cause
-collateral damage to a disk holding the root file system? There is no
-easy answer to this and many other related questions.
-
-If you have any suggestion about sg (or improving (the accuracy of) this
-document) please contact me.
+Rather than document the driver's interface here, version information
+is provided plus pointers (i.e. URLs) where to find documentation
+and examples.
+
+
+Major versions of the sg driver
+===============================
+There are three major versions of sg found in the linux kernel (lk):
+      - sg version 1 (original) from 1992 to early 1999 (lk 2.2.5) . 
+	It is based in the sg_header interface structure.
+      - sg version 2 from lk 2.2.6 in the 2.2 series. It is based on
+	an extended version of the sg_header interface structure.
+      - sg version 3 found in the lk 2.4 series (and the lk 2.5 series).
+	It adds the sg_io_hdr interface structure.
+
+
+Sg driver documentation
+=======================
+The most recent documentation of the sg driver is kept at the Linux
+Documentation Project's (LDP) site: 
+http://www.linuxdoc.org/HOWTO/SCSI-Generic-HOWTO
+This describes the sg version 3 driver found in the lk 2.4 series.
+The LDP renders documents in single and multiple page HTML, postscript
+and pdf. This document can also be found at:
+http://www.torque.net/sg/p/sg_v3_ho.html
+
+Documentation for the version 2 sg driver found in the lk 2.2 series can
+be found at http://www.torque.net/sg/p/scsi-generic.txt . A larger version
+is at:  http://www.torque.net/sg/p/scsi-generic_long.txt .
+
+The original documentation for the sg driver (prior to lk 2.2.6) can be
+found at http://www.torque.net/sg/p/original/SCSI-Programming-HOWTO.txt
+and in the LDP archives.
+
+A changelog with brief notes can be found in the
+/usr/src/linux/include/scsi/sg.h file. Note that the glibc maintainers copy 
+and edit this file (removing its changelog for example) before placing it 
+in /usr/include/scsi/sg.h . Driver debugging information and other notes 
+can be found at the top of the /usr/src/linux/drivers/scsi/sg.c file.
+
+A more general description of the Linux SCSI subsystem of which sg is a 
+part can be found at http://www.linuxdoc.org/HOWTO/SCSI-2.4-HOWTO .
+
+
+Example code and utilities
+==========================
+There are two packages of sg utilities:
+  - sg3_utils   for the sg version 3 driver found in lk 2.4
+  - sg_utils    for the sg version 2 (and original) driver found in lk 2.2
+                and earlier
+Both packages will work in the lk 2.4 series however sg3_utils offers more
+capabilities. They can be found at: http://www.torque.net/sg and 
+freshmeat.net
+
+Another approach is to look at the applications that use the sg driver.
+These include cdrecord, cdparanoia, SANE and cdrdao.
+
+
+Mapping of Linux kernel versions to sg driver versions
+======================================================
+Here is a list of linux kernels in the 2.4 series that had new version
+of the sg driver:
+      lk 2.4.0 : sg version 3.1.17
+      lk 2.4.7 : sg version 3.1.19 
+      lk 2.4.10 : sg version 3.1.20  **
+      lk 2.4.17 : sg version 3.1.22 
+
+** There were 3 changes to sg version 3.1.20 by third parties in the
+   next six linux kernel versions.
+
+For reference here is a list of linux kernels in the 2.2 series that had 
+new version of the sg driver:
+      lk 2.2.0 : original sg version [with no version number]
+      lk 2.2.6 : sg version 2.1.31
+      lk 2.2.8 : sg version 2.1.32
+      lk 2.2.10 : sg version 2.1.34 [SG_GET_VERSION_NUM ioctl first appeared]
+      lk 2.2.14 : sg version 2.1.36
+      lk 2.2.16 : sg version 2.1.38
+      lk 2.2.17 : sg version 2.1.39
+      lk 2.2.20 : sg version 2.1.40
+
+The lk 2.5 development series has recently commenced and it currently
+contains sg version 3.5.23 which is functionally equivalent to sg
+version 3.1.22 found in lk 2.4.17 .

-	The scsi support in the linux kernel can be modularized in a
-number of different ways depending upon the needs of the end user.  To
-understand  your options, we should first define a few terms.

-	The scsi-core contains the core of scsi support.  Without it
-you can do nothing with any of the other scsi drivers.  The scsi core
-support can be a module (scsi_mod.o), or it can be built into the kernel.
-If the core is a module, it must be the first scsi module loaded, and
-if you unload the modules, it will have to be the last one unloaded.
-
-	The individual upper and lower level drivers can be loaded in any
-order once the scsi core is present in the kernel (either compiled in
-or loaded as a module).  The disk driver (sd_mod.o), cdrom driver (sr_mod.o),
-tape driver (st.o) and scsi generics driver (sg.o) represent the upper level
-drivers to support the various assorted devices which can be controlled.
-You can for example load the tape driver to use the tape drive, and then
-unload it once you have no further need for the driver (and release the
-associated memory).
-
-	The lower level drivers are the ones that support the
-individual cards that are supported for the hardware platform that you
-are running under.  Examples are aha1542.o to drive Adaptec 1542
-cards.  Rather than list the drivers which *can* be modularized, it is

+Notes on using modules in the SCSI subsystem
+============================================
+The scsi support in the linux kernel can be modularized in a number of 
+different ways depending upon the needs of the end user.  To understand
+your options, we should first define a few terms.
+
+The scsi-core (also known as the "mid level") contains the core of scsi 
+support.  Without it you can do nothing with any of the other scsi drivers.
+The scsi core support can be a module (scsi_mod.o), or it can be built into
+the kernel. If the core is a module, it must be the first scsi module 
+loaded, and if you unload the modules, it will have to be the last one 
+unloaded.  In practice the modprobe and rmmod commands (and "autoclean")
+will enforce the correct ordering of loading and unloading modules in
+the SCSI subsystem.
+
+The individual upper and lower level drivers can be loaded in any order 
+once the scsi core is present in the kernel (either compiled in or loaded
+as a module).  The disk driver (sd_mod.o), cdrom driver (sr_mod.o),
+tape driver ** (st.o) and scsi generics driver (sg.o) represent the upper 
+level drivers to support the various assorted devices which can be 
+controlled.  You can for example load the tape driver to use the tape drive, 
+and then unload it once you have no further need for the driver (and release
+the associated memory).
+
+The lower level drivers are the ones that support the individual cards that
+are supported for the hardware platform that you are running under. Those
+individual cards are often called Host Bus Adapters (HBAs). For example the
+aic7xxx.o driver is used to control all recent SCSI controller cards from 
+Adaptec. Almost all lower level drivers can be built either as modules or 
+built into the kernel.
+
+
+** There is a variant of the st driver for controlling OnStream tape
+   devices. Its module name is osst.o .

+	some cameras (ones that actually have the LED wired to the control pin,
+	and not just hardwired to be on all the time).
+
+  NAME: dump_bridge
+  TYPE: integer (Boolean)
+  DEFAULT: 0
+  DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system
+	log. Only useful for serious debugging/development purposes.
+
+  NAME: dump_sensor
+  TYPE: integer (Boolean)
+  DEFAULT: 0
+  DESC: Dumps the sensor register values to the system log. Only useful for
+	serious debugging/development purposes.
+
+  NAME: printph
+  TYPE: integer (Boolean)
+  DEFAULT: 0
+  DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This
+	is only useful if you are trying to debug problems with the isoc data
+	stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be
+	warned that this dumps a large number of messages to your kernel log.
+
+  NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv
+  TYPE: integer (0-63 for phy and phuv, 0-255 for rest)
+  DEFAULT: OV511 default values
+  DESC: These are registers 70h - 77h of the OV511, which control the
+	prediction ranges and quantization thresholds of the compressor, for
+	the Y and UV channels in the horizontal and vertical directions. See
+	the OV511 or OV511+ data sheet for more detailed descriptions. These
+	normally do not need to be changed.
+
+  NAME: lightfreq
+  TYPE: integer (0, 50, or 60)
+  DEFAULT: 0 (use sensor default)
+  DESC: Sets the sensor to match your lighting frequency. This can reduce the
+	appearance of "banding", i.e. horizontal lines or waves of light and
+	dark that are often caused by artificial lighting. Valid values are:
+		0 - Use default (depends on sensor, most likely 60 Hz)
+		50 - For European and Asian 50 Hz power
+		60 - For American 60 Hz power
+
+  NAME: bandingfilter
+  TYPE: integer (Boolean)
+  DEFAULT: 0 (off)
+  DESC: Enables the sensor´s banding filter exposure algorithm. This reduces
+	or stabilizes the "banding" caused by some artificial light sources
+	(especially fluorescent). You might have to set lightfreq correctly for
+	this to work right. As an added bonus, this sometimes makes it
+	possible to capture your monitor´s output.
+
+  NAME: fastset
+  TYPE: integer (Boolean)
+  DEFAULT: 0 (off)
+  DESC: Allows picture settings (brightness, contrast, color, and hue) to take
+	effect immediately, even in the middle of a frame. This reduces the
+	time to change settings, but can ruin frames during the change. Only
+	affects OmniVision sensors.
+
+  NAME: force_palette
+  TYPE: integer (Boolean)
+  DEFAULT: 0 (off)
+  DESC: Forces the palette (color format) to a specific value. If an
+	application requests a different palette, it will be rejected, thereby
+	forcing it to try others until it succeeds. This is useful for forcing
+	greyscale mode with a color camera, for example. Supported modes are:

+  NAME: tuner
+  TYPE: integer
+  DEFAULT: -1 (autodetect)
+  DESC: This sets the exact type of the tuner module in a device. This is set
+	automatically based on the custom ID of the OV511 device. In cases
+	where this fails, you can override this auto-detection. Please see
+	linux/drivers/media/video/tuner.h for a complete list.
+
+  NAME: backlight
+  TYPE: integer (Boolean)
+  DEFAULT: 0 (off)
+  DESC: Setting this flag changes the exposure algorithm for OmniVision sensors
+	such that objects in the camera's view (i.e. your head) can be clearly
+	seen when they are illuminated from behind. It reduces or eliminates
+	the sensor's auto-exposure function, so it should only be used when
+	needed. Additionally, it is only supported with the OV6620 and OV7620.
+
+  NAME: unit_video
+  TYPE: Up to 16 comma-separated integers
+  DEFAULT: 0,0,0... (automatically assign the next available minor(s))
+  DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices.
+	For example, "unit_video=1,3" will make the driver use /dev/video1 and
+	/dev/video3 for the first two devices it detects. Additional devices
+	will be assigned automatically starting at the first available device
+	node (/dev/video0 in this case). Note that you cannot specify 0 as a
+	minor number. This feature requires kernel version 2.4.5 or higher.
+
+  NAME: remove_zeros
+  TYPE: integer (Boolean)
+  DEFAULT: 0 (do not skip any incoming data)
+  DESC: Setting this to 1 will remove zero-padding from incoming data. This
+	will compensate for the blocks of corruption that can appear when the
+	camera cannot keep up with the speed of the USB bus (eg. at low frame
+	resolutions). This feature is always enabled when compression is on.
+ 
 WORKING FEATURES:
- o Color streaming/capture at 640x480, 448x336, 384x288, 352x288, and 320x240
- o RGB24, RGB565, YUV420, YUV422, YUYV, and YUV422P color
- o Monochrome
+ o Color streaming/capture at most widths and heights that are multiples of 8.
+ o RGB24, RGB565, YUV420/YUV420P, YUV422/YUYV, and YUV422P color
+ o Monochrome (use force_palette=1 to enable)
  o Setting/getting of saturation, contrast, brightness, and hue (only some of
    them work the OV7620 and OV7620AE)
  o /proc status reporting
+ o SAA7111A video capture support at 320x240 and 640x480
+ o Compression support
 
 EXPERIMENTAL FEATURES:
- o fix_rgb_offset: Sometimes works, but other times causes errors with xawtv and
-   corrupted frames. If you have a very fast CPU, you can try it.
- o Snapshot mode (only works with some read() based apps; see below for more)
- o OV6620 sensor support
- o GBR422 parsing
- o 160x120
-
-TODO:
- o Fix the noise / grainy image problem.
- o Get compression working. It would be a nice addition as it improves
-   frame rate quite a bit. OmniVision wouldn't tell me how the algorithm works,
-   so we can't really work on that yet. Please kindly inform OmniVision that you
-   would like them to release their specifications to the Linux community.
- o YUV422
- o Fix fixFrameRGBoffset(). It is not stable yet with streaming video.
- o V4L2 support (Probably not until it goes into the kernel)
- o Get rid of the memory management functions (put them in videodev.c??)
- o Setting of contrast and brightness not working with 7620/7620AE
- o Driver/camera state save/restore for when USB supports suspend/resume
- o Unstable on SMP systems
- o OV7620/OV6620 experience frame corruption with moving objects
- o OV6620 is too dark
- o 176x144 support
- o Driver sometimes hangs upon close() with OHCI
- o The image should always be written properly to the mmap'ed buffer as long as
-   the requested image size is at least the minimum size. This will likely
-   require a rewrite of all the parsing code.
+ o OV6630 sensor support
+ o Banding filter
+ o SMP compatibility
+
+TO-DO:
+ o V4L2 support (This will be done after the next kernel patch release)
+ o Setting of hue not working with OV7620
+ o Setting of contrast and hue not working with OV7620AE
+ o OV8600 sensor support (Not used in anything yet)
+ o OV518/OV518+ support (all that's needed is the decompressor)
+ o cams >= 3 not working

+Linux driver for STV0680 based USB cameras
+
+Copyright, 2001, Kevin Sisson
+
+
+INTRODUCTION:
+
+STMicroelectronics produces the STV0680B chip, which comes in two 
+types, -001 and -003. The -003 version allows the recording and downloading 
+of sound clips from the camera, and allows a flash attachment. Otherwise, 
+it uses the same commands as the -001 version. Both versions support a 
+variety of SDRAM sizes and sensors, allowing for a maximum of 26 VGA or 20 
+CIF pictures. The STV0680 supports either a serial or a usb interface, and 
+video is possible through the usb interface.
+
+The following cameras are known to work with this driver, although any 
+camera with Vendor/Product codes of 0553/0202 should work:
+
+Aiptek Pencam (various models)
+Nisis QuickPix 2
+Radio Shack 'Kid's digital camera' (#60-1207)
+At least one Trust Spycam model
+Several other European brand models
+
+WHAT YOU NEED:
+
+-	USB support
+-	VIDEO4LINUX support
+
+More information about USB support for linux can be found at:
+http://www.linux-usb.org
+
+
+MODULE OPTIONS:
+
+When the driver is compiled as a module, you can set a "swapRGB=1"
+option, if necessary, for those applications that require it 
+(such as xawtv). However, the driver should detect and set this 
+automatically, so this option should not normally be used.
+
+
+KNOWN PROBLEMS:
+
+The driver seems to work better with the usb-ohci than the usb-uhci host 
+controller driver. 
+
+HELP:
+
+The latest info on this driver can be found at:
+http://personal.clt.bellsouth.net/~kjsisson or at
+http://stv0680-usb.sourceforge.net
+
+Any questions to me can be send to:  kjsisson@bellsouth.net

+Compaq iPAQ driver
+
+  This driver can be used to connect to Compaq iPAQ PDAs running
+  Windows CE 3.0 using a USB autosync cable. It has been tested only on
+  the Compaq H3135. It should work with the H3600 and later models too.
+  It may work with other CE based handhelds as well.
+
+  The driver presents a serial interface (usually on /dev/ttyUSB0) over
+  which one may run ppp and establish a TCP/IP link to the iPAQ. Once this
+  is done, you can transfer files, backup, download email etc. The most
+  significant advantage of using USB is speed - you can get 73 to 113
+  kbytes/sec for download/upload to the iPAQ.
+
+  The driver works intermittently with the usb-uhci driver but quite
+  reliably with the uhci driver. Make sure you have the right driver
+  loaded - usb-uhci is often the default.
+
+  You must setup hotplug to invoke pppd as soon as the iPAQ is connected.
+  A ppp script like the one below may be used:
+
+	#!/bin/bash
+
+	MYIP=linux.box.ip
+	REMOTEIP=ipaq.ip
+	MYDNS=my.dns.server
+	killall -9 pppd
+	/usr/sbin/pppd /dev/ttyUSB0 \
+	connect "/usr/sbin/chat -v TIMEOUT 60 CLIENT 'CLIENTSERVER\c'" \
+	nocrtscts local debug passive $MYIP:$REMOTEIP ms-dns $MYDNS noauth \
+	proxyarp
+
+  You must also download and install asyncd from http://synce.sourceforge.net
+  This is required to emulate keep-alive packets which are exchanged by
+  ActiveSync and the iPAQ.
+
+  On connecting the cable, you should see the usual "Device Connected",
+  "User Authenticated" messages flash by on your iPAQ. Once connected,
+  you can use Win CE programs like ftpView, Pocket Outlook from the iPAQ
+  and other synce utilities from the Linux side. Remember to enable IP
+  forwarding. 
+
+  To use Pocket IE, follow the instructions given at
+  http://www.tekguru.co.uk/EM500/usbtonet.htm to achieve the same thing
+  on Win98. Omit the proxy server part; Linux is quite capable of forwarding
+  packets unlike Win98. Another modification is required at least for the
+  iPAQ - disable autosync by going to the Start/Settings/Connections menu
+  and unchecking the "Automatically synchronize ..." box. Go to
+  Start/Programs/Connections, connect the cable and select "usbdial" (or
+  whatever you named your new USB connection). You should finally wind
+  up with a "Connected to usbdial" window with status shown as connected.
+  Now start up PIE and browse away.
+
+  If it doesn't work for some reason, load both the usbserial and ipaq module
+  with the module parameter "debug" set to 1 and examine the system log.
+  You can also try soft-resetting your iPAQ before attempting a connection.
+
+  For any questions or problems with the driver, please contact Ganesh
+  Varadarajan <ganesh@veritas.com>

+KL5KUSB105 chipset / PalmConnect USB single-port adapter
+  
+Current status:
+  The driver was put together by looking at the usb bus transactions
+  done by Palm's driver under Windows, so a lot of functionality is
+  still missing.  Notably, serial ioctls are sometimes faked or not yet
+  implemented.  Support for finding out about DSR and CTS line status is
+  however implemented (though not nicely), so your favorite autopilot(1)
+  and pilot-manager -daemon calls will work.  Baud rates up to 115200
+  are supported, but handshaking (software or hardware) is not, which is
+  why it is wise to cut down on the rate used is wise for large
+  transfers until this is settled.
+  
+Options supported:
+  If this driver is compiled as a module you can pass the following
+  options to it:
+  debug			- extra verbose debugging info
+  			  (default: 0; nonzero enables)
+  use_lowlatency	- use low_latency flag to speed up tty layer
+			  when reading from from the device.
+			  (default: 0; nonzero enables)
+
+  See http://www.uuhaus.de/linux/palmconnect.html for up-to-date
+  information on this driver.

+ * Revision 1.29  2002/01/14 16:10:01  pkj
+ * Allocate the receive buffers dynamically. The static 4kB buffer was
+ * too small for the peaks. This means that we can get rid of the extra
+ * buffer and the copying to it. It also means we require less memory
+ * under normal operations, but can use more when needed (there is a
+ * cap at 64kB for safety reasons). If there is no memory available
+ * we panic(), and die a horrible death...
+ *
+ * Revision 1.28  2001/12/18 15:04:53  johana
+ * Cleaned up write_rs485() - now it works correctly without padding extra
+ * char.
+ * Added sane default initialisation of rs485.

+ * Revision 1.24  2001/11/12 15:10:05  pkj
+ * Total redesign of the receiving part of the serial driver.
+ * Uses eight chained descriptors to write to a 4kB buffer.
+ * This data is then serialised into a 2kB buffer. From there it
+ * is copied into the TTY's flip buffers when they become available.
+ * A lot of copying, and the sizes of the buffers might need to be
+ * tweaked, but all in all it should work better than the previous
+ * version, without the need to modify the TTY code in any way.
+ * Also note that erroneous bytes are now correctly marked in the

+************************************************************

+************************************************************
+
+The Direct Rendering Manager (drm) is a device-independent kernel-level
+device driver that provides support for the XFree86 Direct Rendering
+Infrastructure (DRI).
+
+The DRM supports the Direct Rendering Infrastructure (DRI) in four major
+ways:
+
+    1. The DRM provides synchronized access to the graphics hardware via
+       the use of an optimized two-tiered lock.
+
+    2. The DRM enforces the DRI security policy for access to the graphics
+       hardware by only allowing authenticated X11 clients access to
+       restricted regions of memory.
+
+    3. The DRM provides a generic DMA engine, complete with multiple
+       queues and the ability to detect the need for an OpenGL context
+       switch.
+
+    4. The DRM is extensible via the use of small device-specific modules
+       that rely extensively on the API exported by the DRM module.
+
+
+Documentation on the DRI is available from:
+    http://precisioninsight.com/piinsights.html
+
+For specific information about kernel-level support, see:
+
+    The Direct Rendering Manager, Kernel Support for the Direct Rendering
+    Infrastructure

+
+    Changes:
+
+    2001/12/13 BenH	New implementation
+    2001/12/15 BenH	Add support for "byte" and "quick"
+                        transfers. Add i2c_xfer routine.
+
+    My understanding of the various modes supported by keywest are:
+
+     - Dumb mode : not implemented, probably direct tweaking of lines
+     - Standard mode : simple i2c transaction of type
+         S Addr R/W A Data A Data ... T
+     - Standard sub mode : combined 8 bit subaddr write with data read
+         S Addr R/W A SubAddr A Data A Data ... T
+     - Combined mode : Subaddress and Data sequences appended with no stop
+         S Addr R/W A SubAddr S Addr R/W A Data A Data ... T
+
+    Currently, this driver uses only Standard mode for i2c xfer, and
+    smbus byte & quick transfers ; and uses StandardSub mode for
+    other smbus transfers instead of combined as we need that for the
+    sound driver to be happy

+* 04/02/01 trw - reworked the includes, so kgdb wouldn't get confused.
+* 04/17/01 trw - added ifdef CONFIG_PM for 2.4.x non-pm kernels. static pmprint.
+* 04/19/01 trw - reworked all of the wrapper macros to keep native 2.4.x code
+*		 predominate in the driver.

+ *
+ *	26/01/2001 ed 0.1 Iain Sandoe
+ *		- added version info.
+ *		- moved dbdma command buffer allocation to PMacXXXSqSetup()
+ *		- fixed up beep dbdma cmd buffers
+ *
+ *	08/02/2001 [0.2]
+ *		- make SNDCTL_DSP_GETFMTS return the correct info for the h/w
+ *		- move soft format translations to a separate file
+ *		- [0.3] make SNDCTL_DSP_GETCAPS return correct info.
+ *		- [0.4] more informative machine name strings.
+ *		- [0.5]
+ *		- record changes.
+ *		- made the default_hard/soft entries.
+ *	04/04/2001 [0.6]
+ *		- minor correction to bit assignments in awacs_defs.h
+ *		- incorporate mixer changes from 2.2.x back-port.
+ *		- take out passthru as a rec input (it isn't).
+ *              - make Input Gain slider work the 'right way up'.
+ *              - try to make the mixer sliders more logical - so now the
+ *                input selectors are just two-state (>50% == ON) and the
+ *                Input Gain slider handles the rest of the gain issues.
+ *              - try to pick slider representations that most closely match
+ *                the actual use - e.g. IGain for input gain... 
+ *              - first stab at over/under-run detection.
+ *		- minor cosmetic changes to IRQ identification.
+ *		- fix bug where rates > max would be reported as supported.
+ *              - first stab at over/under-run detection.
+ *              - make use of i2c for mixer settings conditional on perch
+ *                rather than cuda (some machines without perch have cuda).
+ *              - fix bug where TX stops when dbdma status comes up "DEAD"
+ *		  so far only reported on PowerComputing clones ... but.
+ *		- put in AWACS/Screamer register write timeouts.
+ *		- part way to partitioning the init() stuff
+ *		- first pass at 'tumbler' stuff (not support - just an attempt
+ *		  to allow the driver to load on new G4s).
+ *      01/02/2002 [0.7] - BenH
+ *	        - all sort of minor bits went in since the latest update, I
+ *	          bumped the version number for that reason

- * from user space into our buffer at the right frequency. They take care about
- * how much data there's actually to read, how much buffer space there is and
- * to convert samples into the right frequency/encoding. They will only work on

- * if the user didn't write a multiple of the current sample size. They both
- * return the number of bytes they've used from both streams so you may detect
- * such a situation. Luckily all programs should be able to cope with that.
- *
- * I think I've optimized anything as far as one can do in plain C, all
- * variables should fit in registers and the loops are really short. There's
- * one loop for every possible situation. Writing a more generalized and thus
- * parameterized loop would only produce slower code. Feel free to optimize
- * this in assembler if you like. :)
- *
- * I think these routines belong here because they're not yet really hardware
- * independent, especially the fact that the Falcon can play 16bit samples

+ /* Record capability notes 30/01/2001:
+  * At present these observations apply only to pmac LL driver (the only one
+  * that can do record, at present).  However, if other LL drivers for machines
+  * with record are added they may apply.
+  *
+  * The fragment parameters for the record and play channels are separate.
+  * However, if the driver is opened O_RDWR there is no way (in the current OSS
+  * API) to specify their values independently for the record and playback
+  * channels.  Since the only common factor between the input & output is the
+  * sample rate (on pmac) it should be possible to open /dev/dspX O_WRONLY and
+  * /dev/dspY O_RDONLY.  The input & output channels could then have different
+  * characteristics (other than the first that sets sample rate claiming the
+  * right to set it for ever).  As it stands, the format, channels, number of
+  * bits & sample rate are assumed to be common.  In the future perhaps these
+  * should be the responsibility of the LL driver - and then if a card really
+  * does not share items between record & playback they can be specified
+  * separately.
+*/
+
+/* Thread-safeness of shared_resources notes: 31/01/2001
+ * If the user opens O_RDWR and then splits record & play between two threads
+ * both of which inherit the fd - and then starts changing things from both
+ * - we will have difficulty telling.
+ *
+ * It's bad application coding - but ...
+ * TODO: think about how to sort this out... without bogging everything down in
+ * semaphores.
+ *
+ * Similarly, the OSS spec says "all changes to parameters must be between
+ * open() and the first read() or write(). - and a bit later on (by
+ * implication) "between SNDCTL_DSP_RESET and the first read() or write() after
+ * it".  If the app is multi-threaded and this rule is broken between threads
+ * we will have trouble spotting it - and the fault will be rather obscure :-(
+ *
+ * We will try and put out at least a kmsg if we see it happen... but I think
+ * it will be quite hard to trap it with an -EXXX return... because we can't
+ * see the fault until after the damage is done.

+ *
+ *   TODO:
+ *   -----
+ *   * Enable DRC since the TiBook speakers are less than good
+ *   * Enable control over input line 2 (is this connected?)
+ *   * Play with the dual six-stage cascading biquad filtering to see how
+ *     we can use it to our advantage (currently not implemented)
+ *   * Reorganise driver a bit to make it cleaner and easier to work with
+ *     (read: use the header file more :-P)
+ *   * Implement sleep support
+ *
+ *   Version 0.4:
+ *   ------------
+ *   * Balance control finally works (can someone document OSS better please?)
+ *   * Moved to a struct for common values referenced in the driver
+ *   * Put stubs in for sleep/wake-up support for now.  This will take some
+ *     experimentation to make sure that the timing is right, since the
+ *     TAS hardware requires specific timing while enabling low-power mode.
+ *     I may cheat for now and just reset the chip on wake-up, but I'd rather
+ *     not if I don't have to.
+ *
+ *   Version 0.3:
+ *   ------------
+ *   * Fixed volume control
+ *   * Added bass and treble control
+ *   * Added PCM line level control (mixer 1 in the TAS manual)

+ * requests coming from the line discipline. This is done by chaining them
+ * in lists of struct ipaq_packet, each packet holding a maximum of
+ * PACKET_SIZE bytes.
+ *
+ * ipaq_write() can be called from bottom half context; hence we can't
+ * allocate memory for packets there. So we initialize a pool of packets at
+ * the first open and maintain a freelist.
+ *
+ * The value of PACKET_SIZE was empirically determined by

+ *  
+ * Thanks to STMicroelectronics for information on the usb commands, and 
+ * to Steve Miller at STM for his help and encouragement while I was 
+ * writing this driver.
+ *
+ * This driver is based heavily on the 
+ * Endpoints (formerly known as AOX) se401 USB Camera Driver
+ * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
+ *
+ * Still somewhat based on the Linux ov511 driver.

+ * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+ *
+ * History: 
+ * ver 0.1 October, 2001. Initial attempt. 
+ *
+ * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
+ *                         function, made more stable (?)
+ *
+ * ver 0.21 Nov, 2001.     Added gamma correction and white balance, 
+ *                         due to Alexander Schwartz. Still trying to 
+ *                         improve stablility. Moved stuff into stv680.h
+ *
+ * ver 0.22 Nov, 2001.	   Added sharpen function (by Michael Sweet, 
+ *                         mike@easysw.com) from GIMP, also used in pencam. 
+ *                         Simple, fast, good integer math routine.
+ *
+ * ver 0.23 Dec, 2001 (gkh)
+ * 			   Took out sharpen function, ran code through
+ * 			   Lindent, and did other minor tweaks to get
+ * 			   things to work properly with 2.5.1
+ *
+ * ver 0.24 Jan, 2002 (kjs) 
+ *                         Fixed the problem with webcam crashing after
+ *                         two pictures. Changed the way pic is halved to 
+ *                         improve quality. Got rid of green line around 
+ *                         frame. Fix brightness reset when changing size 
+ *                         bug. Adjusted gamma filters slightly.

+ * 2001_08_29 - 0.3 - pavel: played a little bit more. Experimental mmap support. For some fun,
+ 			get gqcam-0.9, compile it and run. Better than dd ;-).
+ * 2001_08_29 - 0.4 - pavel: added shutter speed control (not much functional)
+ 			kill update_params if it does not seem to work for you.
+ * 2001_08_30 - 0.5 - pavel: fixed stupid bug with update_params & vicam_bulk

 ChangeLog for smbfs.
 
+2001-12-31 René Scharfe <l.s.r@web.de>
+
+	* inode.c: added smb_show_options to show mount options in /proc/mounts
+	* inode.c, getopt.c, getopt.h: merged flag and has_arg in struct option
+	* inode.c: use S_IRWXUGO where appropriate
+
+2001-12-22 Urban Widmark <urban@teststation.com>
+
+	* file.c, proc.c: Fix problems triggered by the "fsx test"
+
 2001-09-17 Urban Widmark <urban@teststation.com>
 
 	* proc.c: Use 4096 (was 512) as the blocksize for better write
