Yes, it is a part of Skylake driver, "hdadsp" is the name of sound card created on machine when using HDA generic machine driver. This machine driver is made of 2 .c files:
- skl_hda_dsp_common.c - skl_hda_dsp_generic.c
btw, this machine driver is also used by SOF, but name is prefixed:
- HDA with DSP and SST FW -> "hda-dsp" as the card name
- HDA with DSP and SOF FW -> "sof-hda-dsp" as the card name
And of course without DSP we have also:
- HDA no DSP -> "HDA-Intel" as card name
While we try to share what is possible, the topologies will be different for all three, and thus different UCM files are needed.
Br, Kai
UCMs for "sof-hda-dsp" and "HDA-Intel" are already present on the alsa-ucm-conf repo, only the "hda-dsp" one is missing right now. There is also a second e-mail thread with patch adding topology for hda-dsp which is compatible with this UCM configuration.
Thanks, Mateusz
