      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: 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 short cables support · 49521f97
      Bartlomiej Zolnierkiewicz authored
      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: add ide_tune_dma() helper · 29e744d0
      Bartlomiej Zolnierkiewicz authored
      After reworking the code responsible for selecting the best DMA
      transfer mode it is now possible to add generic ide_tune_dma() helper.
      
      Convert some IDE PCI host drivers to use it (the ones left need more work).

      ide: rework the code for selecting the best DMA transfer mode (v3) · 2d5eaa6d
      Bartlomiej Zolnierkiewicz authored
      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: add ide_set_dma() helper (v2) · 3608b5d7
      Bartlomiej Zolnierkiewicz authored
      * add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return
        -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly)
         0 when DMA needs to be enabled  (== need to call ->ide_dma_on)
         1 when DMA setting shouldn't be changed
      * fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly

      ide: add ide_use_fast_pio() helper (v3) · 7569e8dc
      Bartlomiej Zolnierkiewicz authored
      * add ide_use_fast_pio() helper for use by host drivers
      
      * add DMA capability and hwif->autodma checks to ide_use_dma()
      
        - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1)
      
          [ for the IT8211/2 in SMART mode this check shouldn't be made but since
            in it821x_fixups() we set DMA bit explicitly:
      
                     if(strstr(id->model, "Integrated Technology Express")) {
                             /* In raid mode the ident block is slightly buggy
                                We need to set the bits so that the IDE layer knows
                                LBA28. LBA48 and DMA ar valid */
                             id->capability |= 3;            /* LBA28, DMA */
      
             we are better off using generic helper if we can ]
      
        - ide-cris driver didn't set ->autodma
      
          [ before the patch hwif->autodma was only checked in the chipset specific
            hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check()
            function so there no behavior change here ]
      
      v2:
      * updated patch description (thanks to Alan Cox for the feedback)
      
      v3:
      * updated for scc_pata driver
