+What:	sound-slot/service-* module aliases and related clutters in
+	sound/sound_core.c
+When:	August 2010
+Why:	OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
+	(14) and requests modules using custom sound-slot/service-*
+	module aliases.  The only benefit of doing this is allowing
+	use of custom module aliases which might as well be considered
+	a bug at this point.  This preemptive claiming prevents
+	alternative OSS implementations.
+
+	Till the feature is removed, the kernel will be requesting
+	both sound-slot/service-* and the standard char-major-* module
+	aliases and allow turning off the pre-claiming selectively via
+	CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss
+	kernel parameter.
+
+	After the transition phase is complete, both the custom module
+	aliases and switches to disable it will go away.  This removal
+	will also allow making ALSA OSS emulation independent of
+	sound_core.  The dependency will be broken then too.

+Early Patching
+~~~~~~~~~~~~~~
+When CONFIG_SND_HDA_PATCH_LOADER=y is set, you can pass a "patch" as a
+firmware file for modifying the HD-audio setup before initializing the
+codec.  This can work basically like the reconfiguration via sysfs in
+the above, but it does it before the first codec configuration.
+
+A patch file is a plain text file which looks like below:
+
+------------------------------------------------------------------------
+  [codec]
+  0x12345678 0xabcd1234 2
+
+  [model]
+  auto
+
+  [pincfg]
+  0x12 0x411111f0
+
+  [verb]
+  0x20 0x500 0x03
+  0x20 0x400 0xff
+
+  [hint]
+  hp_detect = yes
+------------------------------------------------------------------------
+
+The file needs to have a line `[codec]`.  The next line should contain
+three numbers indicating the codec vendor-id (0x12345678 in the
+example), the codec subsystem-id (0xabcd1234) and the address (2) of
+the codec.  The rest patch entries are applied to this specified codec
+until another codec entry is given.
+
+The `[model]` line allows to change the model name of the each codec.
+In the example above, it will be changed to model=auto.
+Note that this overrides the module option.
+
+After the `[pincfg]` line, the contents are parsed as the initial
+default pin-configurations just like `user_pin_configs` sysfs above.
+The values can be shown in user_pin_configs sysfs file, too.
+
+Similarly, the lines after `[verb]` are parsed as `init_verbs`
+sysfs entries, and the lines after `[hint]` are parsed as `hints`
+sysfs entries, respectively.
+
+The hd-audio driver reads the file via request_firmware().  Thus,
+a patch file has to be located on the appropriate firmware path,
+typically, /lib/firmware.  For example, when you pass the option
+`patch=hda-init.fw`, the file /lib/firmware/hda-init-fw must be
+present.
+
+The patch module option is specific to each card instance, and you
+need to give one file name for each instance, separated by commas.
+For example, if you have two cards, one for an on-board analog and one 
+for an HDMI video board, you may pass patch option like below:
+------------------------------------------------------------------------
+    options snd-hda-intel patch=on-board-patch,hdmi-patch

+	  With this option enabled, the kernel will claim all OSS device
+	  numbers if any OSS support (native or emulation) is enabled
+	  whether the respective module is loaded or not and try to load the
+	  appropriate module using sound-slot/service-* and char-major-*
+	  module aliases when one of the device numbers is opened.  With
+	  this option disabled, kernel will only claim actually in-use
+	  device numbers and opening a missing device will generate only the
+	  standard char-major-* aliases.
+
+	  The only visible difference is use of additional module aliases
+	  and whether OSS sound devices appear multiple times in
+	  /proc/devices.  sound-slot/service-* module aliases are scheduled
+	  to be removed (ie. PRECLAIM won't be available) and this option is
+	  to make the transition easier.  This option can be overridden
+	  during boot using the kernel parameter soundcore.preclaim_oss.
+
+	  Disabling this allows alternative OSS implementations.
+
+	  Please read Documentation/feature-removal-schedule.txt for
+	  details.
+
+	  If unusre, say Y.
