      Bartlomiej Zolnierkiewicz authored
      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)

      ide: remove ->ide_dma_check (take 2) · 0ae2e178
      Bartlomiej Zolnierkiewicz authored
      * Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend
        on BIOS for programming device/controller for DMA.  Set it in cy82c693,
        generic, ns87415, opti621 and trm290 host drivers.
      
      * Add IDE_HFLAG_VDMA host flag for host drivers using VDMA.  Set it in cs5520
        host driver.
      
      * 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 ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding
        dummy config_drive_for_dma() inline.
      
      * 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.

      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.

      ACPI support for IDE devices · e3a59b4d
      Hannes Reinecke authored
      This patch implements ACPI integration for generic IDE devices.
      The ACPI spec mandates that some methods are called during suspend and
      resume. And consequently there most modern Laptops cannot resume
      properly without it.
      
      According to the spec, we should call '_GTM' (Get Timing) upon suspend
      to store the current IDE adapter settings.
      Upon resume we should call '_STM' (Set Timing) to initialize the
      adapter with the stored settings; afterwards '_GTF' (Get Taskfile)
      should be called which returns a buffer with some IDE initialisation
      commands. Those commands should be passed to the drive.
      
      There are two module params which control the behaviour of this patch:
      
      'ide=noacpi'
      	Do not call any ACPI methods (Disables any ACPI method calls)
      'ide=acpigtf'
      	Enable execution of _GTF methods upon resume.
      	Has no effect if 'ide=noacpi' is set.
      'ide=acpionboot'
      	Enable execution of ACPI methods during boot.
      	This might be required on some machines if 'ide=acpigtf' is
      	selected as some machines modify the _GTF information
      	depending on the drive identification passed down with _STM.

      [PATCH] remove blk_queue_activity_fn · 2b02a179
      Boaz Harrosh authored
      While working on bidi support at struct request level
      I have found that blk_queue_activity_fn is actually never used.
      The only user is in ide-probe.c with this code:
      
      	/* enable led activity for disk drives only */
      	if (drive->media == ide_disk && hwif->led_act)
      		blk_queue_activity_fn(q, hwif->led_act, drive);
      
      And led_act is never initialized anywhere.
      (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18)
      Unless it is all for future use off course.
      (this patch is against linux-2.6-block.git as off 2006/12/4)

      [SPARC]: Kill __irq_itoa(). · c6387a48
      David S. Miller authored
      This ugly hack was long overdue to die.
      
      It was a way to print out Sparc interrupts in a more freindly format,
      since IRQ numbers were arbitrary opaque 32-bit integers which vectored
      into PIL levels.  These 32-bit integers were not necessarily in the
      0-->NR_IRQS range, but the PILs they vectored to were.
      
      The idea now is that we will increase NR_IRQS a little bit and use a
      virtual<-->real IRQ number mapping scheme similar to PowerPC.
      
      That makes this IRQ printing hack irrelevant, and furthermore only a
      handful of drivers actually used __irq_itoa() making it even less
      useful.

      [PATCH] timeout at boottime with NEC3500A (and possibly others) when inserted a CD in it · 284e4238
      Marcello Maggioni authored
      From: Marcello Maggioni <hayarms@gmail.com>
      
      Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH
      MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a
      CD/DVD is inserted into the tray when the system is booted and if
      before the OS bootup the BIOS checked for the presence of a bootable
      CD/DVD into the drive, during the IDE probe phase the drive may
      result busy and remain so for the next 25/30 seconds . This cause the
      drive to be skipped during the booting phase and not begin usable
      until the next reboot (if the reboot goes well and the drive doesn't
      timeout again).
      
      Solution: Rising the timeout time from 10 seconds to 35 seconds
      (during these 35 seconds every drive should wake up for sure
      according to the tests I've done).
