      ide: make ide_hwif_t.ide_dma_host_on void (v2) · ccf35289
      Bartlomiej Zolnierkiewicz authored
      * since ide_hwif_t.ide_dma_host_on is called either when drive->using_dma == 1
        or when return value is discarded make it void, also drop "ide_" prefix
      * make __ide_dma_host_on() void and drop "__" prefix
      
      v2:
      * while at it rename atiixp_ide_dma_host_on() to atiixp_dma_host_on()
        and sgiioc4_ide_dma_host_on() to sgiioc4_dma_host_on().

      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

      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

      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.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
