      ide: add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag · 4db90a14
      Bartlomiej Zolnierkiewicz authored
      * Add IDE_HFLAG_ABUSE_SET_DMA_MODE host flag and use it to decide
        what to do with transfer modes < XFER_PIO_0 in ide_set_xfer_rate().
      
      * Set IDE_HFLAG_ABUSE_SET_DMA_MODE in host drivers that need it
        (aec62xx, amd74xx, cs5520, cs5535, hpt34x, hpt366, pdc202xx_old,
        serverworks, tc86c001 and via82cxxx) and cleanup ->set_dma_mode
        methods in host drivers that don't (IDE core code guarantees that
        ->set_dma_mode will be called only for modes which are present
        in SWDMA/MWDMA/UDMA masks).
      
      While at it:
      
      * Add IDE_HFLAGS_HPT34X/HPT3XX/PDC202XX/SVWKS define in
        hpt34x/hpt366/pdc202xx_old/serverworks host driver.
      
      There should be no functionality changes caused by this patch.

      ide: remove hwif->autodma and drive->autodma · 9ff6f72f
      Bartlomiej Zolnierkiewicz authored
      * 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: remove ->ide_dma_check (take 2) · 0ae2e178
      Bartlomiej Zolnierkiewicz authored
      * 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.

      cs5530/sc1200: add PIO autotune fallback to ->ide_dma_check · 3f019eea
      Bartlomiej Zolnierkiewicz authored
      * Add PIO autotune fallback to ->ide_dma_check.
      
        Since cs5530/sc1200 allow separate PIO and DMA timings, and cs5530/sc1200
        always set ->autotune this change shouldn't have any other effect than
        bringing these drivers in-line with other host drivers wrt ->ide_dma_check
        implementations.
      
      * Fix ->ide_dma_check to return "-1" if DMA cannot be set.
      
      * Bump driver version.

      ide: move ide_config_drive_speed() calls to upper layers (take 2) · 88b2b32b
      Bartlomiej Zolnierkiewicz authored
      * Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16.
      
      * Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program 
        the host for the transfer mode after programming the device.  Set it
        in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac
        and via82cxxx host drivers.
      
      * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely
        skip programming of host/device for the transfer mode ("smart" hosts).
        Set it in it821x host driver and check it in ide_tune_dma().
      
      * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all
        direct ->set_pio_mode/->speedproc users to use these helpers.
      
      * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc
        methods to callers.
      
      * Rename ->speedproc method to ->set_dma_mode, make it void and update
        all implementations accordingly.
      
      * Update ide_set_xfer_rate() comments.
      
      * Unexport ide_config_drive_speed().
      
      v2:
      * Fix issues noticed by Sergei:
        - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt
          to setting DMA modes from sc1200_set_pio_mode() to do_special()
        - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma()
        - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode()
        - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode()
        - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL
        - don't set ->set_{pio,dma}_mode on it821x in "smart" mode
        - fix build problem in pmac.c
        - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c
        - improve patch description
      
      Changes in behavior caused by this patch:
      - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change
        PIO mode if it821x controller is in "smart" mode
      - removal of two debugging printk-s (from cs5530.c and sc1200.c)
      - transfer modes 0x00-0x07 passed from user space may be programmed twice on
        the device (not really an issue since 0x00 is not supported correctly by
        any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid)

      ide: add ide_set{_max}_pio() (take 4) · 26bcb879
      Bartlomiej Zolnierkiewicz authored
      * Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
        and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.
      
      * Add set_pio_mode_abuse() for checking if host driver has a non-standard
        ->tuneproc() implementation and use it in do_special().
      
      * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
        the maximum PIO mode supported by the host), also add ide_set_max_pio()
        wrapper for ide_set_pio() to use for auto-tuning.  Convert users of
        ->tuneproc to use ide_set{_max}_pio() where possible.  This leaves only
        do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
        a direct users of ->tuneproc.
      
      * Remove no longer needed ide_get_best_pio_mode() calls and printk-s
        reporting PIO mode selected from ->tuneproc implementations.
      
      * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.
      
      * Remove stale comment from ide_config_drive_speed().
      
      v2:
      * Fix "ata_" prefix (Noticed by Jeff).
      
      v3:
      * Minor cleanups/fixups per Sergei's suggestions.
      
      v4:
      * Fix compile problem in drivers/ide/pci/cmd640.c
        (Noticed by Andrew Morton).
      
      * Improve some ->set_pio_mode comments.
