      ide: add short cables support · 49521f97
      由 Bartlomiej Zolnierkiewicz 提交于 
      This patch allows users to override both host and device side cable detection
with "ideX=ata66" kernel parameter.  Thanks to this it should be now possible
to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable
instead of 80-pin one.

Next patches add automatic detection of some systems using short cables.

Changes:

* Rename hwif->udma_four to hwif->cbl and make it u8.

* Convert all existing users accordingly (use ATA_CBL_* defines while at it).  

* Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three().

* Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

      ide: make void and rename ide_dma_timeout() method · c283f5db
      由 Sergei Shtylyov 提交于 
      Since ide_dma_timeout() method's result is discarded, make it return 'void'.
While at it, drop 'ide_' from the method's name, drop the '__' prefix from
the default method's name, and do some cleanups in this method driver-wise:

- in ide-dma.c, au1xxx-ide.c, and pdc202xx_old.c, define/use 'hwif' variable;

- in au1xxx-ide.c, get rid of commented out printk();

- in sl82c105.c, get rid of unnecessary variables.

While at it, rename the method to dma_lost_irq(), drop the '__' prefix from the
default method's name, and do some cleanups in this method driver-wise:

- in sgiioc4.c, rearrange the code to call the resetproc() method directly.

      pdc202xx_old: rewrite mode programming code (v2) · 4fce3164
      由 Bartlomiej Zolnierkiewicz 提交于 
      This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.

Rewrite mode programming code:

* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
  even if both devices on the channel are not DMA capable and after reset

* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
  as they need to be setup correctly also for PIO only devices, plus IORDY
  wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
  ATAPI devices

* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
  (driver sets ->autotune to 1 so PIO modes are always programmed => lower
   nibble of register A never equals 4 => "chipset_is_set" is always true)

* enable PIO mode programming for all ATAPI devices
  (it was limited to ->media == ide_cdrom devices)

* remove extra reads of registers A/B/C, don't read register D et all

* do clearing / programming of registers A/B/C in one go
  (gets rid of extra PCI config space read/write cycle)

* set initial values of drive_conf/AP/BP/CP variables to zero
  (paranoia for the case when PCI reads fail)

* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
  (ide_rate_filter() takes care of it)

* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)

* fix bitmasks for clearing bits of register B:

  - when programming DMA mode bit 0x10 of register B was cleared which
    resulted in overclocked PIO timing setting (iff PIO0 was used)

  - when programming PIO mode bits 0x18 weren't cleared so suboptimal
    timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
    and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)

* add FIXME comment about missing locking for 66MHz clock register

Also while at it:

* remove unused defines

* do a few cosmetic / CodingStyle fixes

* bump driver version

v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
  registers is used only by the debugging code so cover "drive_conf"
  PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO
  (Noticed by Sergei Shtylyov)

      ide: cable detection fixes (take 2) · 7f8f48af
      由 Bartlomiej Zolnierkiewicz 提交于 
      Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough
review of the cable detection code...

* print user-friendly warning about limiting the maximum transfer speed
  to UDMA33 (and the reason behind it) when 80-wire cable is not detected,
  also while at it cleanup eighty_ninty_three() a bit

* use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs:
  - bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1
    were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case
    (please see FIXME comment in eighty_ninty_three() for more details)
  - CONFIG_IDEDMA_IVB=y/n cases were interchanged
  - check for SATA devices was missing

* remove private cable warnings from pdc_202xx{old,new} drivers now that core
  code provides this functionality (plus, in pdc202xx_new case the test could
  give false warnings for ATAPI devices because pdc202xx_new driver doesn't
  even support ATAPI DMA)

      ide: rework the code for selecting the best DMA transfer mode (v3) · 2d5eaa6d
      由 Bartlomiej Zolnierkiewicz 提交于 
      Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch.

* add ide_hwif_t.udma_filter hook for filtering UDMA mask
  (use it in alim15x3, hpt366, siimage and serverworks drivers)
* add ide_max_dma_mode() for finding best DMA mode for the device
  (loosely based on some older libata-core.c code)
* convert ide_dma_speed() users to use ide_max_dma_mode()
* make ide_rate_filter() take "ide_drive_t *drive" as an argument instead
  of "u8 mode" and teach it to how to use UDMA mask to do filtering
* use ide_rate_filter() in hpt366 driver
* remove no longer needed ide_dma_speed() and *_ratemask()
* unexport eighty_ninty_three()

v2:
* rename ->filter_udma_mask to ->udma_filter
  [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ]

v3:
* updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space
  originated transfer mode change requests when 100MHz clock is used)

      ide: fix UDMA/MWDMA/SWDMA masks (v3) · 18137207
      由 Bartlomiej Zolnierkiewicz 提交于 
      * use 0x00 instead of 0x80 to disable ->{ultra,mwdma,swdma}_mask
* add udma_mask field to ide_pci_device_t and use it to initialize
  ->ultra_mask in aec62xx, cmd64x, pdc202xx_{new,old} and piix drivers
* fix UDMA masks to match with chipset specific *_ratemask()

   filtering method - done in the next patch)

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
