      Driver core: convert block from raw kobjects to core devices · edfaa7c3
      Kay Sievers authored
      This moves the block devices to /sys/class/block. It will create a
      flat list of all block devices, with the disks and partitions in one
      directory. For compatibility /sys/block is created and contains symlinks
      to the disks.

      ide: skip ide_wait_not_busy() on noprobe-disks · 8266105b
      Jonas Stare authored
      There is a problem in some hardware where the kernel will stall for
      35 seconds waiting for disks that don't exist. This patch will skip
      waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
      as a kernel option and the disk is not marked as 'present' (like when
      you set the geometry by hand).
      
      If no noprobe-option is set the code will work (more or less) as the
      original but if set the code will skip the ide_wait_not_busy() for
      that drive. Even if there would be a drive there and it is still busy
      afterwards it should not matter since it isn't probed for later.
      
      The code also honors the MAX_DRIVES variable instead of assuming that
      there will be two harddrives on the bus.

      ide: add ide_device_add() · 8447d9d5
      Bartlomiej Zolnierkiewicz authored
      * Add ide_device_add() helper and convert host drivers to use it
        instead of open-coded variants.
      
      * Make ide_pci_setup_ports() and do_ide_setup_pci_device()
        take 'u8 *idx' argument instead of 'ata_index_t *index'.
      
      * Remove no longer needed ata_index_t.
      
      * Unexport probe_hwif_init() and make it static.
      
      * Unexport ide_proc_register_port().
      
      There should be no functionality changes caused by this patch
      (sgiioc4.c: ide_proc_register_port() requires hwif->present
       to be set and it won't be set if probe_hwif_init() fails).

      ATAPI devices with broken DMA support should be handled by DMA blacklist
      and for debugging purposes we have new shiny "hdx=nodma" kernel paremeter.

      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)

        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 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.

      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().

      v3:

      v4:
      * Fix compile problem in drivers/ide/pci/cmd640.c
        (Noticed by Andrew Morton).

      it821x: RAID mode fixes · 0380dad4
      Bartlomiej Zolnierkiewicz authored
      The DMA support for RAID mode broke after:
      
      	commit 71ef51cc
      	Author: Jens Axboe <axboe@suse.de>
      	Date:   Fri Jul 28 09:02:17 2006 +0200
      
      	    [PATCH] it821x: fix ide dma setup bug
      
      	    Only enable dma for a valid speed setting.
      
      	    Signed-off-by: Jens Axboe <axboe@suse.de>
      
      	commit 0a8348d0
      	Author: Jens Axboe <axboe@suse.de>
      	Date:   Fri Jul 28 08:58:26 2006 +0200
      
      	    [PATCH] ide: if the id fields looks screwy, disable DMA
      
      	    It's the safer choice. Originally due to a bug in itx821x, but a
      	    generally sound thing to do.
      
      	    Signed-off-by: Jens Axboe <axboe@suse.de>
      
      However it worked by pure luck before Jens' fixes: bogus ide_dma_enable()
      usage in it821x driver combined with loosy check in ide_dma_verbose() allowed
      the hardware to operate in DMA mode.  When these problems were fixed the DMA
      support broke...
      
      The source root for the regression turned out to be that the it821x.c code
      was clearing too much of id->field_valid.  The IDE core code was using the
      original value of id->field_valid to do the tuning but later DMA got disabled
      in ide_dma_verbose() because of the incorrect id->field_valid fixup.  Fix it.
      
      While at it:
      
      * Do fixup() after probing the drives but before tuning them (which is also
        OK w.r.t. ide_undecoded_slave() fixup).  This change fixes device IDENTIFY
        data to be consistent before/after the tuning and allows us to remove extra
        re-tuning of drives from it821x_fixups().
      
      * Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has
        DMA capable bit set (this is just to tell the IDE core that DMA is
        supported since it821x firmware takes care of DMA mode programming).
      
      * Don't touch timing registers and don't program transfer modes on devices
        et all when in RAID mode - depend solely on firmware to do the tuning
        (as suggested by Alan Cox and done in libata pata_it821x driver).
      
      Thanks for testing the patch goes out to Thomas Kuther.
