      ide: add struct ide_dma_ops (take 3) · 5e37bdc0
      由 Bartlomiej Zolnierkiewicz 提交于 
      Add struct ide_dma_ops and convert core code + drivers to use it.

While at it:

* Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods.

* Drop "ide_" "infixes" from DMA methods.

* au1xxx-ide.c:
  - use auide_dma_{test_irq,end}() directly in auide_dma_timeout()

* pdc202xx_old.c:
  - drop "old_" "infixes" from DMA methods

* siimage.c:
  - add siimage_dma_test_irq() helper
  - print SATA warning in siimage_init_one()

* Remove no longer needed ->init_hwif implementations.

v2:
* Changes based on review from Sergei:
  - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/
  - s/drive->hwif/hwif/ in idefloppy_pc_intr().
  - fix patch description w.r.t. au1xxx-ide changes
  - fix au1xxx-ide build
  - fix naming for cmd64*_dma_ops
  - drop "ide_" and "old_" infixes
  - s/hpt3xxx_dma_ops/hpt37x_dma_ops/
  - s/hpt370x_dma_ops/hpt370_dma_ops/
  - use correct DMA ops for HPT302/N, HPT371/N and HPT374
  - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/

v3:
* Two bugs slipped in v2 (noticed by Sergei):
  - use correct DMA ops for HPT374 (for real this time)
  - handle HPT370/HPT370A properly

      ide: add struct ide_port_ops (take 2) · ac95beed
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Move hooks for port/host specific methods from ide_hwif_t to
  'struct ide_port_ops'.

* Add 'const struct ide_port_ops *port_ops' to 'struct ide_port_info'
  and ide_hwif_t.

* Update host drivers and core code accordingly.

While at it:

* Rename ata66_*() cable detect functions to *_cable_detect() to match
  the standard naming. (Suggested by Sergei Shtylyov)

v2:
* Fix build for bast-ide. (Noticed by Andrew Morton)

      ide: DMA reporting and validity checking fixes (take 3) · 3ab7efe8
      由 Bartlomiej Zolnierkiewicz 提交于 
      * ide_xfer_verbose() fixups:
  - beautify returned mode names
  - fix PIO5 reporting
  - make it return 'const char *'

* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().

* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
  DMA info in identify block.

* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().

  As a result DMA won't be tuned or will be disabled after tuning if device
  reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
  same checks while the IDE device is probed by ide-{cd,disk} device driver).

* Remove no longer needed ide_dma_verbose().

This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:

       hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
       skipping word 93 validity check
        , UDMA(66)

and later debugged by Mark Lord to be caused by:

        ide_dma_verbose()
                printk( ... "2048kB Cache");
        eighty_ninty_three()
                printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
        ide_dma_verbose()
                printk(", UDMA(66)"

Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.

v2:
* fixes suggested by Randy:
  - use KERN_CONT for printk()-s in ide-{cd,disk}.c
  - don't remove argument name from ide_xfer_verbose() declaration

v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()
  (spotted by Sergei).

* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).

* Fix ide_find_dma_mode() to report the correct mode ('mode' after being
  limited by 'req_mode').
