      ide: DMA reporting and validity checking fixes (take 3) · 3ab7efe8
      由 Bartlomiej Zolnierkiewicz 提交于 
      * ide_xfer_verbose() fixups:
  - beautify returned mode names
  - fix PIO5 reporting
  - make it return 'const char *'

* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().

* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
  DMA info in identify block.

* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().

  As a result DMA won't be tuned or will be disabled after tuning if device
  reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
  same checks while the IDE device is probed by ide-{cd,disk} device driver).

* Remove no longer needed ide_dma_verbose().

This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:

       hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
       skipping word 93 validity check
        , UDMA(66)

and later debugged by Mark Lord to be caused by:

        ide_dma_verbose()
                printk( ... "2048kB Cache");
        eighty_ninty_three()
                printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
        ide_dma_verbose()
                printk(", UDMA(66)"

Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.

v2:
* fixes suggested by Randy:
  - use KERN_CONT for printk()-s in ide-{cd,disk}.c
  - don't remove argument name from ide_xfer_verbose() declaration

v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()
  (spotted by Sergei).

* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).

* Fix ide_find_dma_mode() to report the correct mode ('mode' after being
  limited by 'req_mode').

      ide-disk: workaround for buggy HPA support on ST340823A (take 3) · b0244a00
      由 Bartlomiej Zolnierkiewicz 提交于 
      This disk reports total number of sectors instead of maximum sector address
in response to READ_NATIVE_MAX_ADDRESS command and also happily accepts
SET_MAX_ADDRESS command with the bogus value.  This results in +1 sector
capacity being used and errors on attempts to use the last sector.

...
hdd: Host Protected Area detected.
        current capacity is 78165360 sectors (40020 MB)
        native  capacity is 78165361 sectors (40020 MB)
hdd: Host Protected Area disabled.
...
hdd: reading: block=78165360, sectors=1, buffer=0xc1e63000
hdd: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdd: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=78165360, sector=78165360
...

Add hpa_list[] table and workaround the issue in idedisk_check_hpa().

v2:
* Add missing export and improve patch description a bit.

v3:
* Add list termination.  (From Mikko)

Fixes kernel bugzilla bug #8816.

Thanks to Mikko for investigating the issue and helping with this patch.

      ide: HPA detect from resume · 0d2157f7
      由 Lee Trager 提交于 
      Currently when system which have HPA require HPA to be detected and
disabled upon resume from RAM or disk. The current IDE drivers do not do
this nor does libata (obviously it since it doesn't support HPA yet).

I have implemented this into the current IDE drivers and it has been
tested by many others since 7/15/2006 in bug number 6840:

	http://bugzilla.kernel.org/show_bug.cgi?id=6840

and it has been confirmed to work fine with no problems.

bart: added drv != NULL check to generic_ide_suspend()

      ide: move IDE settings handling to ide-proc.c · 7662d046
      由 Bartlomiej Zolnierkiewicz 提交于 
      * move
	__ide_add_setting()
	ide_add_setting()
	__ide_remove_setting()
	auto_remove_settings()
	ide_find_setting_by_name()
	ide_read_setting()
	ide_write_setting()
	set_xfer_rate()
	ide_add_generic_settings()
	ide_register_subdriver()
	ide_unregister_subdriver()

  from ide.c to ide-proc.c

* set_{io_32bit,pio_mode,using_dma}() cannot be marked static now, fix it

* rename ide_[un]register_subdriver() to ide_proc_[un]register_driver(),
  update device drivers to use new names

* add CONFIG_IDE_PROC_FS=n versions of ide_proc_[un]register_driver()
  and ide_add_generic_settings()

* make ide_find_setting_by_name(), ide_{read,write}_setting()
  and ide_{add,remove}_proc_entries() static

* cover IDE settings code in device drivers with CONFIG_IDE_PROC_FS #ifdef,
  also while at it cover with CONFIG_IDE_PROC_FS #ifdef ide_driver_t.proc

* remove bogus comment from ide.h

* cover with CONFIG_IDE_PROC_FS #ifdef .proc and .settings in ide_drive_t

Besides saner code this patch results in the IDE core smaller by ~2 kB
(on x86-32) and IDE disk driver by ~1 kB (ditto) when CONFIG_IDE_PROC_FS=n.

      ide: split off ioctl handling from IDE settings (v2) · 1497943e
      由 Bartlomiej Zolnierkiewicz 提交于 
      * do write permission and min/max checks in ide_procset_t functions

* ide-disk.c: drive->id is always available so cleanup "multcount" setting
  accordingly

* ide-disk.c: "address" setting was incorrectly defined as type TYPE_INTA,
  fix it by using type TYPE_BYTE and updating ide_drive_t->adressing field,
  the bug didn't trigger because this IDE setting uses custom ->set function

* ide.c: add set_ksettings() for handling HDIO_SET_KEEPSETTINGS ioctl

* ide.c: add set_unmaskirq() for handling HDIO_SET_UNMASKINTR ioctl

* handle ioctls directly in generic_ide_ioclt() and idedisk_ioctl()
  instead of using IDE settings to deal with them

* remove no longer needed ide_find_setting_by_ioctl() and {read,write}_ioctl
  fields from ide_settings_t, also remove now unused TYPE_INTA handling

v2:
* add missing EXPORT_SYMBOL_GPL(ide_setting_sem) needed now for ide-disk

      ide: make /proc/ide/ optional · ecfd80e4
      由 Bartlomiej Zolnierkiewicz 提交于 
      All important information/features should be already available through
sysfs and ioctl interfaces.

Add CONFIG_IDE_PROC_FS (CONFIG_SCSI_PROC_FS rip-off) config option,
disabling it makes IDE driver ~5 kB smaller (on x86-32).

While at it add CONFIG_PROC_FS=n versions of proc_ide_{create,destroy}()
and remove no longer needed #ifdefs.
