[PATCH] 2.5.24 IDE 97

From: Bartlomiej Zolnierkiewicz (B.Zolnierkiewicz@elka.pw.edu.pl)
Date: Tue Jul 02 2002 - 17:22:11 EST


This patch is a accumulation of ata-hosts-7/8/9/10/11, ata-autodma
and ata-ata66_check patches previously posted on LKML.

It is independent of IDE 94/95/96.

Wed Jul 3 00:13:31 CEST 2002 ide-clean-97

- add int 'modes_map' and flag 'no_atapi_autodma' to
  struct ata_channel, initialise them in *_init_channel()
  functions

- add int 'map' parameter to ch->udma_setup() functions

- add XFER_UDMA_ALL, XFER_UDMA_80W and rework misc defines
  to ata-timing.h

- convert *_ratemask() functions to *_modes_map(),
  mark them with __init
  affected drivers: alim15x3.c, cmd64x.c, hpt366.c,
                      pdc202xx.c, serverworks.c, sis5513.c

- split aec62xx_udma_setup() to aec62xx_udma_setup()
  and aec62xx_modes_map()

- split config_chipset_for_dma() in pdc202xx.c to
  pdc202xx_udma_setup() and pdc202xx_tx_udma_setup()

- add udma_generic_setup() to pcidma.c, which
          - equals functionality of driver specific udma_setup()
          and config_chipset_for_dma()
        - makes use of ch->modes_map, ch->no_atapi_autodma
          and ch->speedproc()/tuneproc()
        - auto-tunes PIO only if we failed to enable DMA
          (PIO auto-tuning is already handled by ch->tuneproc()
          call in probe.c, it is controlled separetly of autodma)

- convert aec62xx.c, alim15x3.c, amd74xx.c, cmd64x.c, hpt34x.c,
          hpt366.c, it8172.c, pdc202xx.c, piix.c, serverworks.c,
          sis5513.c and via82cxxx.c to new scheme

- this has nice side effect of teaching aec, amd, piix and via
  drivers using DMA blacklist/whitelist

- clean usage of ch->autodma flag in PCI host chips drivers

- remove ATA_F_NOADMA flag from aec62xx.c, hpt34x.c,
  sis5513.c and via82cxxx.c drivers, it's use was bogus
  in these drivers

  only two usages of ATA_F_NOADMA are left (in ide-pci.c),
  probably they can alse be removed due to fact that drivers
  should disable autodma not ide-pci (i.e. hpt34x)

- teach alim15x3.c, cs5530.c, cy82c693.c, hpt34x.c, hpt366.c,
  it8172.c, pdc202xx.c, sis5513.c, sl82c105.c, and trm290.c
  drivers about CONFIG_IDEDMA_AUTO (indirectly through ide-pci)

- make it possible to auto-tune DMA for trm290.c

- always check PIO timings in cs5530.c

- remove ata66_check entry from struct ata_pci_device,
  initialise ch->udma_four directly in *_init_channel()

  this abstraction wasn't needed and it was PCI specific
