      ide: remove hwif->autodma and drive->autodma · 9ff6f72f
      Bartlomiej Zolnierkiewicz 提交于
      * 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)

      Bartlomiej Zolnierkiewicz 提交于
      * Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend

        generic, ns87415, opti621 and trm290 host drivers.

      * 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 init_hwif_it8213() comment.
      
      There should be no functionality changes caused by this patch.

        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:

        - 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)

        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.

      ide: mode limiting fixes for user requested speed changes · 7670df73
      Bartlomiej Zolnierkiewicz 提交于
      * Add an extra argument to ide_max_dma_mode() for passing requested transfer
        mode.  Use it as an upper limit when finding the best DMA for device/host.
      
      * Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
        ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
        ide_find_dma_mode().  Also add inline ide_find_dma_mode() version for
        CONFIG_BLK_DEV_IDEDMA=n case.
      
      * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
        to avoid false warning from eighty_ninty_three().
      
      * Use ide_find_dma_mode() to limit the user requested transfer mode in
        ide_rate_filter().  Also limit the requested mode by host max PIO mode.
      
      
      Above changes make ide_rate_filter() to:
      
      * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
        and 0x25-0x39, values > 0x46 were already clipped down, same for values
        0x25-0x39 but iff UDMA was not supported by the host).
      
      * Clip desired transfer mode down if it is currently unsupported by IDE core
        (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
        not supported by the host).
      
      * Clip desired transfer mode down according to the host capabilities
        (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
        also ->atapi_dma flag was not respected).
      
      * Clip desired transfer mode down according to the device capabilities
        (except PIO modes for now which require mode work) - shouldn't be a
        problem since ide_set_xfer_rate() is called _after_ device has accepted
        given transfer mode.

      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!
