Define the common hd-audio driver and device types to bind over snd_hda_bus_type publicly. This allows to implement other type of device and driver code over hd-audio bus. Now both struct hda_codec and struct hda_codec_driver inherit these new struct hdac_device and struct hdac_driver, respectively. The bus registration is done in subsys_initcall() to assure it before any other driver registrations. Signed-off-by: Takashi Iwai <tiwai@suse.de>

help
|
|
If you have a sound card in your computer, i.e. if it can say more
|
|
than an occasional beep, say Y. Be sure to have all the information
|
|
about your sound card and its configuration down (I/O port,
|
|
interrupt and DMA channel), because you will be asked for it.
|
|
|
|
You want to read the Sound-HOWTO, available from
|
|
<http://www.tldp.org/docs.html#howto>. General information about
|
|
the modular sound system is contained in the files
|
|
<file:Documentation/sound/oss/Introduction>. The file
|
|
<file:Documentation/sound/oss/README.OSS> contains some slightly
|
|
outdated but still useful information as well. Newer sound
|
|
driver documentation is found in <file:Documentation/sound/alsa/*>.
|
|
|
|
If you have a PnP sound card and you want to configure it at boot
|
|
time using the ISA PnP tools (read
|
|
<http://www.roestock.demon.co.uk/isapnptools/>), then you need to
|
|
compile the sound card support as a module and load that module
|
|
after the PnP configuration is finished. To do this, choose M here
|
|
and read <file:Documentation/sound/oss/README.modules>; the module
|
|
will be called soundcore.
|
|
|
|

|

help
|
|
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.
|
|
|
|
If unsure, say Y.

This is used to avoid config and link hard dependencies between the
|
|
sound subsystem and other function drivers completely unrelated to
|
|
sound although they're sharing the AC97 bus. Concerned drivers
|
|
should "select" this.
