For the last few days we have been playing with "vanilla" 5.5 kernel -
one without ton of /skylake patches - to find out how could hda-dsp be
enabled on skl/ kbl+ with the least amount of changes pulled from our
branch possible.
Turned out the addition of this single patch AND topology binary update
got the job done.
Now, how can we proceed with such solution. Can share the topology
binary/ .conf if needed, so anyone interested can check it out.
I am personally interested for tests but I doubt this option is usable
by anyone outside of Intel - additional issues with probe race
conditions with i915, e.g. on Linus' Dell XPS 9350, no DMIC support and
not selected anyways by Jaroslav's new logic, no UCM, and no plans for
the use of the HDMI common codec.
In case you didn't see it, the Skylake driver 'HDaudio codec' option is
suggested as one of the 'unsupported' features here:
