      ide: remove unnecessary writes to HOB taskfile registers · a3bbb9d8
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Set taskfile flags for REQ_TYPE_ATA_TASKFILE requests before
  adding the request to the queue.

* Cleanup execute_drive_cmd().

* Remove unnecessary writes to HOB taskfile registers when using
  LBA48 disk for the following cases:

  - Power Management requests
    (WIN_FLUSH_CACHE[_EXT], WIN_STANDBYNOW1, WIN_IDLEIMMEDIATE commands)

  - special commands (WIN_SPECIFY, WIN_RESTORE, WIN_SETMULT)

  - Host Protected Area support (WIN_READ_NATIVE_MAX, WIN_SET_MAX)

  - /proc/ide/ SMART support (WIN_SMART with SMART_ENABLE,
    SMART_READ_VALUES and SMART_READ_THRESHOLDS subcommands)

  - write cache enabling/disabling in ide-disk
    (WIN_SETFEATURES with SETFEATURES_{EN,DIS}_WCACHE)

  - write cache flushing in ide-disk (WIN_FLUSH_CACHE[_EXT])

  - acoustic management in ide-disk
    (WIN_SETFEATURES with SETFEATURES_{EN,DIS}_AAM)

  - door (un)locking in ide-disk (WIN_DOORLOCK, WIN_DOORUNLOCK)

  - /proc/ide/hd?/identify support (WIN_IDENTIFY)

  - ACPI _GTF taskfiles

      ide: use ide_tf_load() in execute_drive_cmd() · 807e35d6
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Add IDE_TFLAG_OUT_DEVICE taskfile flag to indicate the need of writing
  the Device register and handle it in ide_tf_load().

  Update ide_tf_load() and {do_rw,flagged}_taskfile() users accordingly.

* Use struct ide_taskfile and ide_tf_load() in execute_drive_cmd().

* Make the debugging code dump all taskfile registers for both
  REQ_ATA_TYPE_{CMD,TASK} requests and move it to ide_tf_load()
  so it also covers REQ_ATA_TYPE_TASKFILE requests.

There should be no functionality changes caused by this patch
(unless DEBUG is defined).

      ide: use do_rw_taskfile() in flagged_taskfile() · 74095a91
      由 Bartlomiej Zolnierkiewicz 提交于 
      Based on the earlier work by Tejun Heo.

* Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile()
  function to the callers.

* Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming
  from ide_taskfile_ioctl().  Check it instead of ->tf_out_flags.all.

* Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load
  IDE data register in ide_tf_load().

* Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load
  particular IDE taskfile registers in ide_tf_load().

* Update do_rw_taskfile() and ide_tf_load() users to set respective
  IDE_TFLAG_OUT_* taksfile flags.

* Add task_dma_ok() helper.

* Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load().

* Use do_rw_taskfile() in flagged_taskfile().

* Remove no longer needed 'tf_out_flags' field from ide_task_t.

There should be no functionality changes caused by this patch.

      ide: add ide_no_data_taskfile() helper · 9a3c49be
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Add ide_no_data_taskfile() helper and convert ide_raw_taskfile() w/ NO DATA
  protocol users to use it instead.

* Set ->data_phase explicitly in ide_no_data_taskfile()
  (TASKFILE_NO_DATA is defined as 0x0000).

* Unexport task_no_data_intr().

      ide: add ide_tf_load() helper · 9e42237f
      由 Bartlomiej Zolnierkiewicz 提交于 
      Based on the earlier work by Tejun Heo.

* Add 'tf_flags' field (for taskfile flags) to ide_task_t.

* Add IDE_TFLAG_LBA48 taskfile flag for LBA48 taskfiles.

* Add IDE_TFLAG_NO_SELECT_MASK taskfile flag for __ide_do_rw_disk()
  which doesn't use SELECT_MASK() (looks like a bug but it requires
  some more investigation).

* Split off ide_tf_load() helper from do_rw_taskfile().

* Convert __ide_do_rw_disk() to use ide_tf_load().

There should be no functionality changes caused by this patch.

      ide: add struct ide_taskfile (take 2) · 650d841d
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Don't set write-only ide_task_t.hobRegister[6] and ide_task_t.hobRegister[7]
  in idedisk_set_max_address_ext().

* Add struct ide_taskfile and use it in ide_task_t instead of tfRegister[]
  and hobRegister[].

* Remove no longer needed IDE_CONTROL_OFFSET_HOB define.

* Add #ifndef/#endif __KERNEL__ around definitions of {task,hob}_struct_t.

While at it:

* Use ATA_LBA define for LBA bit (0x40) as suggested by Tejun Heo.

v2:
* Add missing newlines. (Noticed by Sergei)

* Use ~ATA_LBA instead of 0xBF. (Noticed by Sergei)

* Use unnamed unions for error/feature and status/command.
  (Suggested by Sergei).

There should be no functionality changes caused by this patch.

      由 Bartlomiej Zolnierkiewicz 提交于 
      Remove task_ioreg_t typedef from the kernel code (but leave it
in <linux/hdreg.h> for #ifndef/#endif __KERNEL__ case).

While at it also move sata_ioreg_t typedef under #ifndef/#endif __KERNEL__.

v2:
Remove name of the second parameter from ide_execute_command() declaration.
(Noticed by Sergei).

      ide: never called printk statement in ide-taskfile.c::wait_drive_not_busy · b42fa133
      由 Masatake YAMATO 提交于 
      Look at wait_drive_not_busy in drivers/ide/ide-taskfile.c:

    static u8 wait_drive_not_busy(ide_drive_t *drive)
    {
            ide_hwif_t *hwif = HWIF(drive);
            int retries = 100;
            u8 stat;

            /*
             * Last sector was transfered, wait until drive is ready.
             * This can take up to 10 usec, but we will wait max 1 ms
             * (drive_cmd_intr() waits that long).
             */
            while (((stat = hwif->INB(IDE_STATUS_REG)) & BUSY_STAT) && retries--)
                    udelay(10);

            if (!retries)
                    printk(KERN_ERR "%s: drive still BUSY!\n", drive->name);

            return stat;
    }

`printk' is never called because `retries' never holds zero at the
outside of `while' loop: when `retries' holds zero at the while's loop
condition, `retries' will hold -1 at the if condition.

      [PATCH] Split struct request ->flags into two parts · 4aff5e23
      由 Jens Axboe 提交于 
      Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      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!
