A continuation of cleanup work of Intel SST solutions found in
sound/soc/intel/. With two major chapters released last year catpt [1]
and removal of haswell solution [2], time has come for Skylake-driver.
Througout 2019, 2020 and 2021 Skylake-driver has had many fixes applied
and even attempts of refactors as seen in fundamental overhaul [3], IPC
flow adjustments [4] and LARGE_CONFIG overhaul [5] series.
Unfortunately, story repeats itself - problems are found within the core
of a driver. Painting it with different colors does not change the fact
that is it still a house of cards. As changes needed to address those
issues would make Skylake solution incompatible with its previous
revisions, a decision has been made to provide a new solution instead.
In time it would deprecate and replace Skylake-driver.
That solution has been called AVS - from AudioDSP architecture name:
Audio-Voice-Speech. It is meant to provide support for the exact same
range of platforms as its predecessor: SKL, KBL, AML and APL.
Note: this series is dependent upon HDA-series [6] which exposes several
codec-organization functions allowing for reduced code size on
avs-driver side.
Hello,
Despite HDA-series being updated to v2 [1], no changes are required on
the side of this series.
Mark,
Should I resend this one regardless of the above?
Also, is there anything else I can help with or explain further
regarding code-loading and IPC protocol which this series implements?
Regards,
Czarek

Note: this series does not add fully functional driver as its size would
get out of control. Here, focus is put on adding IPC protocol and code
loading code.
