- *
- * 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

- * IDE tuning and bus mastering support for the CS5510/CS5520
- * chipsets
- *
- * The CS5510/CS5520 are slightly unusual devices. Unlike the
- * typical IDE controllers they do bus mastering with the drive in
- * PIO mode and smarter silicon.
- *
- * The practical upshot of this is that we must always tune the
- * drive for the right PIO mode. We must also ignore all the blacklists
- * and the drive bus mastering DMA information.

- * CYPRESS CY82C693 chipset IDE controller
- *
- * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
- * Writing 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.
- * - 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
- *
- * Ancient 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 drives.
- * 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

- *
- * This is slightly peculiar, in that it is a PCI driver,

- * On the plus side, the driver is also smaller/simpler this way.

- * Thanks to HighPoint Technologies for their assistance, and hardware.
- * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his
- * donation of an ABit BP6 mainboard, processor, and memory acellerated
- * development and support.
- *
- *
- * HighPoint has its own drivers (open source except for the RAID part)
- * available from http://www.highpoint-tech.com/BIOS%20+%20Driver/.
- * This may be useful to anyone wanting to work on this driver, however do not
- * trust them too much since the code tends to become less and less meaningful
- * as the time passes... :-/
- *
- * 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
- * Tim Hockin <thockin@sun.com>
- *
- * On hpt366:
- * Reset the hpt366 on error, reset on dma
- * Fix disabling Fast Interrupt hpt366.
- * Mike Waychison <crlf@sun.com>
- *
- * Added support for 372N clocking and clock switching. The 372N needs
- * different clocks on read/write. This requires overloading rw_disk and
- * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
- * keeping me sane.
- * Alan Cox <alan@redhat.com>
- *
- * - fix the clock turnaround code: it was writing to the wrong ports when
- * called for the secondary channel, caching the current clock mode per-
- * channel caused the cached register value to get out of sync with the
- * actual one, the channels weren't serialized, the turnaround shouldn't
- * be done on 66 MHz PCI bus
- * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
- * does not allow for this speed anyway
- * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
- * their primary channel is kind of virtual, it isn't tied to any pins)
- * - fix/remove bad/unused timing tables and use one set of tables for the whole
- * HPT37x chip family; save space by introducing the separate transfer mode
- * table in which the mode lookup is done
- * - use f_CNT value saved by the HighPoint BIOS as reading it directly gives
- * the wrong PCI frequency since DPLL has already been calibrated by BIOS;
- * read it only from the function 0 of HPT374 chips
- * - fix the hotswap code: it caused RESET- to glitch when tristating the bus,
- * and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead
- * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
- * they tamper with its fields
- * - pass to the init_setup handlers a copy of the ide_pci_device_t structure
- * since they may tamper with its fields
- * - prefix the driver startup messages with the real chip name
- * - claim the extra 240 bytes of I/O space for all chips
- * - optimize the UltraDMA filtering and the drive list lookup code
- * - use pci_get_slot() to get to the function 1 of HPT36x/374
- * - cache offset of the channel's misc. control registers (MCRs) being used
- * throughout the driver
- * - only touch the relevant MCR when detecting the cable type on HPT374's
- * function 1
- * - rename all the register related variables consistently
- * - move all the interrupt twiddling code from the speedproc handlers into
- * init_hwif_hpt366(), also grouping all the DMA related code together there
- * - merge HPT36x/HPT37x speedproc handlers, fix PIO timing register mask and
- * separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
- * when setting an UltraDMA mode
- * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
- * the best possible one
- * - clean up DMA timeout handling for HPT370
- * - switch to using the enumeration type to differ between the numerous chip
- * variants, matching PCI device/revision ID with the chip type early, at the
- * init_setup stage
- * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
- * stop duplicating it for each channel by storing the pointer in the pci_dev
- * structure: first, at the init_setup stage, point it to a static "template"
- * with only the chip type and its specific base DPLL frequency, the highest
- * UltraDMA mode, and the chip settings table pointer filled, then, at the
- * init_chipset stage, allocate per-chip instance and fill it with the rest
- * of the necessary information
- * - get rid of the constant thresholds in the HPT37x PCI clock detection code,
- * switch to calculating PCI clock frequency based on the chip's base DPLL
- * frequency
- * - switch to using the DPLL clock and enable UltraATA/133 mode by default on
- * anything newer than HPT370/A (except HPT374 that is not capable of this
- * mode according to the manual)
- * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
- * also fixing the interchanged 25/40 MHz PCI clock cases for HPT36x chips;
- * unify HPT36x/37x timing setup code and the speedproc handlers by joining
- * the register setting lists into the table indexed by the clock selected
- * - set the correct hwif->ultra_mask for each individual chip
- * - add Ultra and MW DMA mode filtering for the HPT37[24] based SATA cards

- * May be copied or modified under the terms of the GNU General Public License

- * Documentation available from

- * Some other documents are NDA.
- *
- * The ITE8212 isn't exactly a standard IDE controller. It has two
- * modes. In pass through mode then it is an IDE controller. In its smart
- * mode its actually quite a capable hardware raid controller disguised
- * as an IDE controller. Smart mode only understands DMA read/write and
- * identify, none of the fancier commands apply. The IT8211 is identical
- * in other respects but lacks the raid mode.
- *
- * Errata:
- * o Rev 0x10 also requires master/slave hold the same DMA timings and
- * cannot do ATAPI MWDMA.
- * o The identify data for raid volumes lacks CHS info (technically ok)
- * but also fails to set the LBA28 and other bits. We fix these in
- * the IDE probe quirk code.
- * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
- * raid then the controller firmware dies
- * o Smart mode without RAID doesn't clear all the necessary identify
- * bits to reduce the command set to the one used
- *
- * This has a few impacts on the driver
- * - In pass through mode we do all the work you would expect
- * - In smart mode the clocking set up is done by the controller generally
- * but we must watch the other limits and filter.
- * - There are a few extra vendor commands that actually talk to the
- * controller but only work PIO with no IRQ.
- *
- * Vendor areas of the identify block in smart mode are used for the
- * timing and policy set up. Each HDD in raid mode also has a serial
- * block on the disk. The hardware extra commands are get/set chip status,
- * rebuild, get rebuild status.
- *
- * In Linux the driver supports pass through mode as if the device was
- * just another IDE controller. If the smart mode is running then
- * volumes are managed by the controller firmware and each IDE "disk"
- * is a raid volume. Even more cute - the controller can do automated
- * hotplug and rebuild.
- *
- * The pass through controller itself is a little demented. It has a
- * flaw that it has a single set of PIO/MWDMA timings per channel so
- * non UDMA devices restrict each others performance. It also has a
- * single clock source per channel so mixed UDMA100/133 performance
- * isn't perfect and we have to pick a clock. Thankfully none of this
- * matters in smart mode. ATAPI DMA is not currently supported.
- *
- * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
- *
- * TODO
- * - ATAPI UDMA is ok but not MWDMA it seems
- * - RAID configuration ioctls
- * - Move to libata once it grows up

-/*
- * Authors:
- * Jaromir Koutek <miri@punknet.cz>,
- * Jan Harkes <jaharkes@cwi.nl>,
- * Mark Lord <mlord@pobox.com>
- * Some parts of code are from ali14xx.c and from rz1000.c.
- *
- * OPTi is trademark of OPTi, Octek is trademark of Octek.
- *
- * I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
- * and disassembled/traced setupvic.exe (DOS program).
- * It increases kernel code about 2 kB.
- * I don't have this card no more, but I hope I can get some in case
- * of needed development.
- * My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
- * It has a place for a secondary connector in circuit, but nothing
- * is there. Also BIOS says no address for
- * 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_set_pio_mode
- * 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.
- *
- * 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.

- *
- * If you have strange problems with nVidia chipset systems please

- * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original
- * SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511
- * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
- *
- * Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
- * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
- * can figure out that we have a more modern and more capable 5513 by looking
- * for the respective NorthBridge IDs.
- *
- * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
- * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
- * ID, while the now ATA-133 capable 5513 still has the same PCI ID.
- * Fortunately the 5513 can be 'unmasked' by fiddling with some config space
- * bits, changing its device id to the true one - 5517 for 961 and 5518 for
- * 962/963.
