Since this is common option for HDA driver to specfiy pre-allocated buffer, we should make this option availble to all HDA driver by moving this to HDA core Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

|
|
Specifies the default pre-allocated buffer-size in kB for the
|
|
HD-audio driver. A larger buffer (e.g. 2048) is preferred
|
|
for systems using PulseAudio. The default 64 is chosen just
|
|
for compatibility reasons.
|
|
|
|
Note that the pre-allocation size can be changed dynamically
|
|
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
