2010-11-29Staging: sst: add ioctls for post processing algorithm interfaceVinod Koul
This patch adds two new ioctls to intel_sst_ctrl device. This i/f can be used by application to send algorithm parameters Signed-off-by: Vinod Koul <vinod.koul@intel.com> [This will need further discussion in the context of the final ALSA interface but is fine for staging, ie anyone who relies on it should expect changes Also fixed a missing kmalloc fail check] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-10-05Staging: sst: Intel SST audio driverVinod Koul
This is the Intel SST audio driver. As compared to the previous versions it has all the printks and other stuff noted cleaned up and more hardware support. The Aava support is disabled in this patch (is_aava resolves to 0) because the Aava board detection logic is not yet upstream. The driver itself is a combination of a traditional ALSA driver and a hardware assisted offload driver which can play audio while the processor is asleep but which can't do all the more interactive stuff. In the general case most software would use the ALSA interface, but the other interface is needed for certain classes of use such as music playback on highly power consumption sensitive devices. This is going to staging primarily because it depends upon the staging memrar driver.
