      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)

      jmicron: make ide jmicron driver play nice with libata ones · ebbc2031
      Tejun Heo authored
      When libata is configured, the device is configured such that SATA and
      PATA ports live in separate functions with different programming
      interfaces.  pata_jmicron and ide jmicron drivers can drive only the
      PATA part.
      
      This patch makes jmicron match PCI class code such that it doesn't
      attach itself to the SATA part preventing the proper ahci driver from
      attaching.
      
      This change is suggested by Bartlomiej.

      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
      
      v2:
      * updated for scc_pata

      atiixp/jmicron/triflex: fix PIO fallback · 39baf8a7
      Bartlomiej Zolnierkiewicz authored
      * atiixp: if DMA can't be used atiixp_config_drive_for_dma() should return 0,
        atiixp_dma_check() will tune the correct PIO mode anyway
      
      * jmicron: if DMA can't be used config_chipset_for_dma() should return 0,
        micron_config_drive_for_dma() will tune the correct PIO mode anyway
      
        config_jmicron_chipset_for_pio(drive, !speed) doesn't program
        device transfer mode for speed != 0 (only wastes some CPU cycles
        on ide_get_best_pio_mode() call) so remove it
      
      * triflex: if DMA can't be used triflex_config_drive_for_dma() should return 0,
        triflex_config_drive_xfer_rate() will tune correct PIO mode anyway
      
      Above changes also fix (theoretical) issue when ->speedproc fails to set
      device transfer mode (i.e. when ide_config_drive_speed() fails to program it)
      but one of DMA transfer modes is already enabled on the device by the BIOS.
      In such scenario ide_dma_enable() will incorrectly return true statement
      and ->ide_dma_check will try to enable DMA on the device.
