- * ALI M14xx chipset EIDE controller
- *
- * Works for ALI M1439/1443/1445/1487/1489 chipsets.
- *
- * Adapted from code developed by derekn@vw.ece.cmu.edu.  -ml
- * Derek's notes follow:
- *
- * I think the code should be pretty understandable,
- * but I'll be happy to (try to) answer questions.
- *
- * The critical part is in the setupDrive function.  The initRegisters
- * function doesn't seem to be necessary, but the DOS driver does it, so
- * I threw it in.
- *
- * I've only tested this on my system, which only has one disk.  I posted
- * it to comp.sys.linux.hardware, so maybe some other people will try it
- * out.
- *
- * Derek Noonburg  (derekn@ece.cmu.edu)
- * 95-sep-26
- *
- * Update 96-jul-13:
- *
- * I've since upgraded to two disks and a CD-ROM, with no trouble, and
- * I've also heard from several others who have used it successfully.
- * This driver appears to work with both the 1443/1445 and the 1487/1489
- * chipsets.  I've added support for PIO mode 4 for the 1487.  This
- * seems to work just fine on the 1443 also, although I'm not sure it's
- * advertised as supporting mode 4.  (I've been running a WDC AC21200 in
- * mode 4 for a while now with no trouble.)  -Derek

- *  This file provides support for the advanced features and bugs

- *
- *  These chips are basically fucked by design, and getting this driver
- *  to work on every motherboard design that uses this screwed chip seems
- *  bloody well impossible.  However, we're still trying.
- *
- *  Version 0.97 worked for everybody.
- *
- *  User feedback is essential.  Many thanks to the beta test team:

- *  liug@mama.indstate.edu, and others.
- *
- *  Version 0.01	Initial version, hacked out of ide.c,
- *			and #include'd rather than compiled separately.
- *			This will get cleaned up in a subsequent release.
- *
- *  Version 0.02	Fixes for vlb initialization code, enable prefetch
- *			for versions 'B' and 'C' of chip by default,
- *			some code cleanup.
- *
- *  Version 0.03	Added reset of secondary interface,
- *			and black list for devices which are not compatible
- *			with prefetch mode. Separate function for setting
- *			prefetch is added, possibly it will be called some
- *			day from ioctl processing code.
- *
- *  Version 0.04	Now configs/compiles separate from ide.c
- *
- *  Version 0.05	Major rewrite of interface timing code.
- *			Added new function cmd640_set_mode to set PIO mode
- *			from ioctl call. New drives added to black list.
- *
- *  Version 0.06	More code cleanup. Prefetch is enabled only for
- *			detected hard drives, not included in prefetch
- *			black list.
- *
- *  Version 0.07	Changed to more conservative drive tuning policy.
- *			Unknown drives, which report PIO < 4 are set to
- *			(reported_PIO - 1) if it is supported, or to PIO0.
- *			List of known drives extended by info provided by
- *			CMD at their ftp site.
- *
- *  Version 0.08	Added autotune/noautotune support.
- *
- *  Version 0.09	Try to be smarter about 2nd port enabling.
- *  Version 0.10	Be nice and don't reset 2nd port.
- *  Version 0.11	Try to handle more weird situations.
- *
- *  Version 0.12	Lots of bug fixes from Laszlo Peter
- *			irq unmasking disabled for reliability.
- *			try to be even smarter about the second port.
- *			tidy up source code formatting.
- *  Version 0.13	permit irq unmasking again.
- *  Version 0.90	massive code cleanup, some bugs fixed.
- *			defaults all drives to PIO mode0, prefetch off.
- *			autotune is OFF by default, with compile time flag.
- *			prefetch can be turned OFF/ON using "hdparm -p8/-p9"
- *			 (requires hdparm-3.1 or newer)
- *  Version 0.91	first release to linux-kernel list.
- *  Version 0.92	move initial reg dump to separate callable function
- *			change "readahead" to "prefetch" to avoid confusion
- *  Version 0.95	respect original BIOS timings unless autotuning.
- *			tons of code cleanup and rearrangement.
- *			added CONFIG_BLK_DEV_CMD640_ENHANCED option
- *			prevent use of unmask when prefetch is on
- *  Version 0.96	prevent use of io_32bit when prefetch is off
- *  Version 0.97	fix VLB secondary interface for sjd@slip.net
- *			other minor tune-ups:  0.96 was very good.
- *  Version 0.98	ignore PCI version when disabled by BIOS
- *  Version 0.99	display setup/active/recovery clocks with PIO mode
- *  Version 1.00	Mmm.. cannot depend on PCMD_ENA in all systems
- *  Version 1.01	slow/fast devsel can be selected with "hdparm -p6/-p7"
- *			 ("fast" is necessary for 32bit I/O in some systems)
- *  Version 1.02	fix bug that resulted in slow "setup times"
- *			 (patch courtesy of Zoltan Hidvegi)

- * CYPRESS CY82C693 chipset IDE controller
- *
- * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
- * Writting the driver was quite simple, since most of the job is
- * done by the generic pci-ide support. 
- * The hard part was finding the CY82C693's datasheet on Cypress's
- * web page :-(. But Altavista solved this problem :-).
- *
- *
- * Notes:
- * - I recently got a 16.8G IBM DTTA, so I was able to test it with
- *   a large and fast disk - the results look great, so I'd say the
- *   driver is working fine :-)
- *   hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA 
- * - this is my first linux driver, so there's probably a lot  of room 
- *   for optimizations and bug fixing, so feel free to do it.
- * - use idebus=xx parameter to set PCI bus speed - needed to calc
- *   timings for PIO modes (default will be 40)
- * - if using PIO mode it's a good idea to set the PIO mode and 
- *   32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
- * - I had some problems with my IBM DHEA with PIO modes < 2
- *   (lost interrupts) ?????
- * - first tests with DMA look okay, they seem to work, but there is a
- *   problem with sound - the BusMaster IDE TimeOut should fixed this
- *
- *
- * History:
- * AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
- * ASK@1999-01-23: v0.33 made a few minor code clean ups
- *                       removed DMA clock speed setting by default
- *                       added boot message
- * ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
- *                       added support to set DMA Controller Clock Speed
- * ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes on some drive
- * ASK@1998-10-29: v0.3 added support to set DMA modes
- * ASK@1998-10-28: v0.2 added support to set PIO modes
- * ASK@1998-10-27: v0.1 first version - chipset detection

- * From: andy@cercle.cts.com (Dyan Wile)
- *
- * Below is a patch for DTC-2278 - alike software-programmable controllers
- * The code enables the secondary IDE controller and the PIO4 (3?) timings on
- * the primary (EIDE). You may probably have to enable the 32-bit support to
- * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
- * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
- * filesystem  corrupted with -u1, but under heavy disk load only :-)
- *
- * This card is now forced to use the "serialize" feature,
- * and irq-unmasking is disallowed.  If io_32bit is enabled,
- * it must be done for BOTH drives on each interface.
- *
- * This code was written for the DTC2278E, but might work with any of these:
- *
- * DTC2278S has only a single IDE interface.
- * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
- * DTC2278E also has serial ports and a printer port
- * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
- *
- * There may be a fourth controller type. The S and D versions use the
- * Winbond chip, and I think the E version does also.

- * development and support.
- *
- * Note that final HPT370 support was done by force extraction of GPL.
- *
- * - add function for getting/setting power status of drive
- * - the HPT370's state machine can get confused. reset it before each dma 
- *   xfer to prevent that from happening.
- * - reset state engine whenever we get an error.
- * - check for busmaster state at end of dma. 
- * - use new highpoint timings.
- * - detect bus speed using highpoint register.
- * - use pll if we don't have a clock table. added a 66MHz table that's
- *   just 2x the 33MHz table.
- * - removed turnaround. NOTE: we never want to switch between pll and
- *   pci clocks as the chip can glitch in those cases. the highpoint
- *   approved workaround slows everything down too much to be useful. in
- *   addition, we would have to serialize access to each chip.
- * 	Adrian Sun <a.sun@sun.com>
- *
- * add drive timings for 66MHz PCI bus,
- * fix ATA Cable signal detection, fix incorrect /proc info
- * add /proc display for per-drive PIO/DMA/UDMA mode and
- * per-channel ATA-33/66 Cable detect.
- * 	Duncan Laurie <void@sun.com>
- *
- * fixup /proc output for multiple controllers

- * ht6560b Timing values:
- *
- * I reviewed some assembler source listings of htide drivers and found
- * out how they setup those cycle time interfacing values, as they at Holtek
- * call them. IDESETUP.COM that is supplied with the drivers figures out
- * optimal values and fetches those values to drivers. I found out that
- * they use IDE_SELECT_REG to fetch timings to the ide board right after
- * interface switching. After that it was quite easy to add code to
- * ht6560b.c.
- *
- * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
- * for hda and hdc. But hdb needed higher values to work, so I guess
- * that sometimes it is necessary to give higher value than IDESETUP
- * gives.   [see cmd640.c for an extreme example of this. -ml]
- *
- * Perhaps I should explain something about these timing values:
- * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
- * of the value is the Active Time  (at). Minimum value 2 is the fastest and
- * the maximum value 15 is the slowest. Default values should be 15 for both.
- * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
- * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
- * similar. If value is too small there will be all sorts of failures.
- *
- * Timing byte consists of
- *	High nibble:  Recovery Cycle Time  (rt)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- *	Low nibble:   Active Cycle Time	   (at)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- * You can obtain optimized timing values by running Holtek IDESETUP.COM
- * for DOS. DOS drivers get their timing values from command line, where
- * the first value is the Recovery Time and the second value is the
- * Active Time for each drive. Smaller value gives higher speed.
- * In case of failures you should probably fall back to a higher value.

+ * The IDE driver uses the single global io_request_lock spinlock to protect
+ * access to the request queues, and to protect the hwgroup->busy flag.

+ * The first thread into the driver for a particular hwgroup sets the
+ * hwgroup->busy flag to indicate that this hwgroup is now active,

+ * queue their new requests and exit immediately.  Note that hwgroup->busy
+ * remains set even when the driver is merely awaiting the next interrupt.
+ * Thus, the meaning is "this hwgroup is busy processing a request".
+ *
+ * When processing of a request completes, the completing thread or IRQ-handler
+ * will start the next request from the queue.  If no more work remains,
+ * the driver will clear the hwgroup->busy flag and exit.
+ *
+ * The io_request_lock (spinlock) is used to protect all access to the

+ *
+ *	There's nothing really useful we can do with an unexpected interrupt,
+ *	other than reading the status register (to clear it), and logging it.
+ *	There should be no way that an irq can happen before we're ready for it,
+ *	so we needn't worry much about losing an "important" interrupt here.
+ *
+ *	On laptops (and "green" PCs), an unexpected interrupt occurs whenever
+ *	the drive enters "idle", "standby", or "sleep" mode, so if the status
+ *	looks "good", we just ignore the interrupt completely.
+ *
+ *	This routine assumes __cli() is in effect when called.
+ *
+ *	If an unexpected interrupt happens on irq15 while we are handling irq14
+ *	and if the two interfaces are "serialized" (CMD640), then it looks like
+ *	we could screw up by interfering with a new request being set up for 
+ *	irq15.
+ *
+ *	In reality, this is a non-issue.  The new command is not sent unless 
+ *	the drive is ready to accept one, in which case we know the drive is
+ *	not trying to interrupt us.  And ide_set_handler() is always invoked
+ *	before completing the issuance of any new drive command, so we will not
+ *	be accidentally invoked as a result of any valid command completion
+ *	interrupt.
+ *
+ *	Note that we must walk the entire hwgroup here. We know which hwif
+ *	is doing the current command, but we don't know which hwif burped
+ *	mysteriously.

- * A hwgroup is a serialized group of IDE interfaces.  Usually there is

- * may have both interfaces in a single hwgroup to "serialize" access.
- * Or possibly multiple ISA interfaces can share a common IRQ by being grouped

- * Note also that several hwgroups can end up sharing a single IRQ,

- * PCI-based systems with off-board IDE controller cards.
- *
- * The IDE driver uses the single global io_request_lock spinlock to protect
- * access to the request queues, and to protect the hwgroup->busy flag.
- *
- * The first thread into the driver for a particular hwgroup sets the
- * hwgroup->busy flag to indicate that this hwgroup is now active,
- * and then initiates processing of the top request from the request queue.
- *
- * Other threads attempting entry notice the busy setting, and will simply
- * queue their new requests and exit immediately.  Note that hwgroup->busy
- * remains set even when the driver is merely awaiting the next interrupt.
- * Thus, the meaning is "this hwgroup is busy processing a request".
- *
- * When processing of a request completes, the completing thread or IRQ-handler
- * will start the next request from the queue.  If no more work remains,
- * the driver will clear the hwgroup->busy flag and exit.
- *
- * The io_request_lock (spinlock) is used to protect all access to the
- * hwgroup->busy flag, but is otherwise not needed for most processing in

+ * The critical part is in the setupDrive function.  The initRegisters
+ * function doesn't seem to be necessary, but the DOS driver does it, so
+ * I threw it in.
+ *
+ * I've only tested this on my system, which only has one disk.  I posted
+ * it to comp.sys.linux.hardware, so maybe some other people will try it
+ * out.

+ * Update 96-jul-13:
+ *
+ * I've since upgraded to two disks and a CD-ROM, with no trouble, and
+ * I've also heard from several others who have used it successfully.
+ * This driver appears to work with both the 1443/1445 and the 1487/1489
+ * chipsets.  I've added support for PIO mode 4 for the 1487.  This
+ * seems to work just fine on the 1443 also, although I'm not sure it's
+ * advertised as supporting mode 4.  (I've been running a WDC AC21200 in
+ * mode 4 for a while now with no trouble.)  -Derek

+ * Below is a patch for DTC-2278 - alike software-programmable controllers
+ * The code enables the secondary IDE controller and the PIO4 (3?) timings on
+ * the primary (EIDE). You may probably have to enable the 32-bit support to
+ * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
+ * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
+ * filesystem  corrupted with -u1, but under heavy disk load only :-)
+ *
+ * This card is now forced to use the "serialize" feature,
+ * and irq-unmasking is disallowed.  If io_32bit is enabled,
+ * it must be done for BOTH drives on each interface.
+ *
+ * This code was written for the DTC2278E, but might work with any of these:
+ *
+ * DTC2278S has only a single IDE interface.
+ * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
+ * DTC2278E also has serial ports and a printer port
+ * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
+ *
+ * There may be a fourth controller type. The S and D versions use the
+ * Winbond chip, and I think the E version does also.

+ *  Version 0.02        Added support for PIO modes, auto-tune
+ *
+ *  Version 0.03        Some cleanups
+ *
+ *  Version 0.05        PIO mode cycle timings auto-tune using bus-speed
+ *
+ *  Version 0.06        Prefetch mode now defaults no OFF. To set

+ *  Version 0.07        Trying to fix CD-ROM detection problem.
+ *                      "Prefetch" mode bit OFF for ide disks and
+ *                      ON for anything else.
+ *
+ *
+ *  HT-6560B EIDE-controller support
+ *  To activate controller support use kernel parameter "ide0=ht6560b".

+ * ht6560b Timing values:
+ *
+ * I reviewed some assembler source listings of htide drivers and found
+ * out how they setup those cycle time interfacing values, as they at Holtek
+ * call them. IDESETUP.COM that is supplied with the drivers figures out
+ * optimal values and fetches those values to drivers. I found out that
+ * they use IDE_SELECT_REG to fetch timings to the ide board right after
+ * interface switching. After that it was quite easy to add code to
+ * ht6560b.c.
+ *
+ * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
+ * for hda and hdc. But hdb needed higher values to work, so I guess
+ * that sometimes it is necessary to give higher value than IDESETUP
+ * gives.   [see cmd640.c for an extreme example of this. -ml]
+ *
+ * Perhaps I should explain something about these timing values:
+ * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
+ * of the value is the Active Time  (at). Minimum value 2 is the fastest and
+ * the maximum value 15 is the slowest. Default values should be 15 for both.
+ * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
+ * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
+ * similar. If value is too small there will be all sorts of failures.
+ *
+ * Timing byte consists of
+ *	High nibble:  Recovery Cycle Time  (rt)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ *	Low nibble:   Active Cycle Time	   (at)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ * You can obtain optimized timing values by running Holtek IDESETUP.COM
+ * for DOS. DOS drivers get their timing values from command line, where
+ * the first value is the Recovery Time and the second value is the
+ * Active Time for each drive. Smaller value gives higher speed.
+ * In case of failures you should probably fall back to a higher value.

+ *
+ *  Thanks are due to Mark Lord for advice and patiently answering stupid
+ *  questions, and all those mugs^H^H^H^Hbrave souls who've tested this,
+ *  especially Andre Hedrick.
+ *
+ *  Version 0.01	Initial version, #include'd in ide.c rather than
+ *                      compiled separately.
+ *                      Reads use Promise commands, writes as before. Drives
+ *                      on second channel are read-only.
+ *  Version 0.02        Writes working on second channel, reads on both
+ *                      channels. Writes fail under high load. Suspect
+ *			transfers of >127 sectors don't work.
+ *  Version 0.03        Brought into line with ide.c version 5.27.
+ *                      Other minor changes.
+ *  Version 0.04        Updated for ide.c version 5.30
+ *                      Changed initialization strategy
+ *  Version 0.05	Kernel integration.  -ml
+ *  Version 0.06	Ooops. Add hwgroup to direct call of ide_intr() -ml
+ *  Version 0.07	Added support for DC4030 variants
+ *			Secondary interface autodetection
+ *  Version 0.08	Renamed to pdc4030.c
+ *  Version 0.09	Obsolete - never released - did manual write request
+ *			splitting before max_sectors[major][minor] available.
+ *  Version 0.10	Updated for 2.1 series of kernels
+ *  Version 0.11	Updated for 2.3 series of kernels
+ *			Autodetection code added.
+ *
+ *  Version 0.90	Transition to BETA code. No lost/unexpected interrupts

+ *
+ * It should now work as a second controller also ('ide1=dc4030') but only
+ * if you DON'T have BIOS V4.44, which has a bug. If you have this version
+ * and EPROM programming facilities, you need to fix 4 bytes:

- * secondary controller (see bellow in ide_init_opti621).
- * I've only tested this on my system, which only has one disk.
- * It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
- * is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
- * lockups). I tried the OCTEK double speed CD-ROM and
- * it does not work! But I can't boot DOS also, so it's probably
- * hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
- * problems) and Seagate 1GB (as slave, WD as master). My experiences
- * with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
- * it slows to about 100kB/s! I don't know why and I have
- * not this drive now, so I can't try it again.
- * I write this driver because I lost the paper ("manual") with
- * settings of jumpers on the card and I have to boot Linux with
- * Loadlin except LILO, cause I have to run the setupvic.exe program
- * already or I get disk errors (my test: rpm -Vf
- * /usr/X11R6/bin/XF86_SVGA - or any big file).
- * Some numbers from hdparm -t /dev/hda:
- * Timing buffer-cache reads:   32 MB in  3.02 seconds =10.60 MB/sec
- * Timing buffered disk reads:  16 MB in  5.52 seconds = 2.90 MB/sec
- * I have 4 Megs/s before, but I don't know why (maybe changes
- * in hdparm test).
- * After release of 0.1, I got some successful reports, so it might work.
- *
- * The main problem with OPTi is that some timings for master
- * and slave must be the same. For example, if you have master
- * PIO 3 and slave PIO 0, driver have to set some timings of
- * master for PIO 0. Second problem is that opti621_tune_drive
- * got only one drive to set, but have to set both drives.
- * This is solved in compute_pios. If you don't set
- * the second drive, compute_pios use ide_get_best_pio_mode
- * for autoselect mode (you can change it to PIO 0, if you want).
- * If you then set the second drive to another PIO, the old value
- * (automatically selected) will be overrided by yours.
- * There is a 25/33MHz switch in configuration
- * register, but driver is written for use at any frequency which get
- * (use idebus=xx to select PCI bus speed).
- * Use ide0=autotune for automatical tune of the PIO modes.
- * If you get strange results, do not use this and set PIO manually
- * by hdparm.
- *
- * Version 0.1, Nov 8, 1996
- * by Jaromir Koutek, for 2.1.8. 
- * Initial version of driver.
- * 
- * Version 0.2
- * Number 0.2 skipped.
- *
- * Version 0.3, Nov 29, 1997
- * by Mark Lord (probably), for 2.1.68
- * Updates for use with new IDE block driver.
- *
- * Version 0.4, Dec 14, 1997
- * by Jan Harkes
- * Fixed some errors and cleaned the code.
- *
- * Version 0.5, Jan 2, 1998
- * by Jaromir Koutek
- * Updates for use with (again) new IDE block driver.
- * Update of documentation.
- * 
- * Version 0.6, Jan 2, 1999
- * by Jaromir Koutek
- * Reversed to version 0.3 of the driver, because
- * 0.5 doesn't work.

+ * A driver for the Griffin Technology, Inc. "PowerMate" USB controller dial.
+ *
+ * v1.0, (c)2002 William R Sowerbutts <will@sowerbutts.com>
+ *
+ * This device is a stainless steel knob which connects over USB. It can measure
+ * clockwise and an+iclockwise rotation. The dial also acts as a pushbutton with
+ * a spring for automatic release. The base c	ntains a pair of LEDs which illuminate
+ * the translucent base. It rotates without limit and reports its relative rotation
+ * back to the host when polled by the USB controller.
+ *
+ * Testing with the knob I have has shown that it measures approxime+ely 96 "clicks"
+ * for one full rotation. Testing with my High Speed Rotation Actuator (ok, it was 
+ * a variable speed cordless electric drill) has shown that the device can measure
+ * speeds of up to 7 clicks either clockwise or an+iclockwise between pollings from

  *
- * 2001_07_07 - 0.1 - christopher: first version
- * 2001_08_28 - 0.2 - pavel: messed it up, but for some fun, try 
- o		while true; do dd if=/dev/video of=/dev/fb0 bs=$[0x1e480] c	unt=1 2> /dev/null; done
-o	      yep, moving pictures.
- * 2001_08_29 - 0.3 - pavel: played a little bit more. Experimental mmap support. F	r some fun,
- o		get gqcam-0.9, compile it and run. Better than dd ;-).
- * 2001_08_29 - 0.4 - pavel: added shutter speed control (not much functional)
- o		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
