ide-pmac: skip conservative PIO "downgrade"

2007-11-13T21:09:15+00:00

We can skip conservative PIO "downgrade" (PIO3 becomes PIO2 etc.) on PMAC.

Problem reported by Mikael.

ide: add hwif->ack_intr hook

2007-10-19T22:32:32+00:00

* Add hwif->ack_intr hook and use it instead of hwif->hw.ack_intr.

* Add missing brackets to cris-v32 and powerpc ide_ack_intr() macros.

ide: add ide_device_add()

2007-10-19T22:32:31+00:00

* Add ide_device_add() helper and convert host drivers to use it
  instead of open-coded variants.

* Make ide_pci_setup_ports() and do_ide_setup_pci_device()
  take 'u8 *idx' argument instead of 'ata_index_t *index'.

* Remove no longer needed ata_index_t.

* Unexport probe_hwif_init() and make it static.

* Unexport ide_proc_register_port().

There should be no functionality changes caused by this patch
(sgiioc4.c: ide_proc_register_port() requires hwif->present
 to be set and it won't be set if probe_hwif_init() fails).

ide: add IDE_HFLAG_NO_ATAPI_DMA host flag

2007-10-18T22:30:06+00:00

Add IDE_HFLAG_NO_ATAPI_DMA host flag and set it in host drivers which
don't support ATAPI DMA.  Then remove no longer needed hwif->atapi_dma.

ide: remove hwif->autodma and drive->autodma

2007-10-16T20:29:58+00:00

* hpt34x.c: disable DMA masks for HPT345
  (hwif->autodma is zero so DMA won't be enabled anyway).

* trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag
  (hwif->autodma is zero so DMA won't be enabled anyway).

* Check noautodma global variable instead of drive->autodma in ide_tune_dma().

  This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris,
  au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers.

* Remove hwif->autodma (it was not checked by IDE core code anyway) and
  drive->autodma (was set by all host drivers - except HPT345/TRM290 special
  cases - unless "ide=nodma" was used).

While at it:
- remove needless printk() from icside.c
- remove stale FIXME/comment from ide-probe.c
- don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c
  (this setting was always later over-ridden by host drivers anyway)

ide: use PCI_VDEVICE() macro

2007-10-16T20:29:56+00:00

While at it:
- make struct pci_device_id tables const
- use PCI_DEVICE_ID_ITE_8213 define in it8213.c
- fix comment in generic.c

ide: remove ->ide_dma_check (take 2)

2007-10-16T20:29:55+00:00

* Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend
  on BIOS for programming device/controller for DMA.  Set it in cy82c693,
  generic, ns87415, opti621 and trm290 host drivers.

* Add IDE_HFLAG_VDMA host flag for host drivers using VDMA.  Set it in cs5520
  host driver.

* Teach ide_tune_dma() about IDE_HFLAG_TRUST_BIOS_FOR_DMA flag.

* Add generic ide_dma_check() helper and remove all open coded ->ide_dma_check
  implementations.  Fix all places checking for presence of ->ide_dma_check
  hook to check for ->ide_dma_on instead.

* Remove no longer needed code from config_drive_for_dma().

* Make ide_tune_dma() static.

v2:
* Fix config_drive_for_dma() return values.

* Fix ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding
  dummy config_drive_for_dma() inline.

* Fix IDE_HFLAG_TRUST_BIOS_FOR_DMA handling in ide_dma_check().

* Fix init_hwif_it8213() comment.

There should be no functionality changes caused by this patch.

ide-pmac: add PIO autotune fallback to ->ide_dma_check

2007-10-16T20:29:55+00:00

Since ide-pmac allows separate PIO and DMA timings, and ide-pmac always sets
->autotune this change shouldn't have any other effect than bringing ide-pmac
driver in-line with other host drivers wrt ->ide_dma_check implementation.
