On Baytrail and Cherrytrail, HDaudio may be fused out or disabled by the BIOS. This driver enables an alternate path to the i915 display registers and DMA. Although there is no hardware path between i915 display and LPE/SST audio clusters, this HDMI capability is referred to in the documentation as "HDMI LPE Audio" so we keep the name for consistency. There is no hardware path or control dependencies with the LPE/SST DSP functionality. The hdmi-lpe-audio driver will be probed when the i915 driver creates a child platform device. Since this driver is neither SoC nor PCI, a new x86 folder is added Additional indirections in the code will be cleaned up in the next series to aid smoother DP integration Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Jerome Anand <jerome.anand@intel.com> 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outdated but still useful information as well.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.
