ide: move IDE settings handling to ide-proc.c

2007-05-09T22:01:10+00:00

* 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)

2007-05-09T22:01:10+00:00

* 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

2007-05-09T22:01:09+00:00

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.

ide: remove ide_drive_t.usage

2007-02-17T01:40:24+00:00

This field is no longer used by the core IDE code so fix ide-{disk,floppy}
drivers to keep openers count in the driver specific objects and remove
it from ide-{cd,scsi,tape} drivers (it was write-only).

[PATCH] Split struct request ->flags into two parts

2006-09-30T18:23:37+00:00

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.

[PATCH] ide: option to disable cache flushes for buggy drives

2006-07-28T06:54:59+00:00

Some drives claim they support cache flushing, but get seriously
confused if you try. Add this option to be able to boot with
barriers enabled by default.
