Subject: ASoC: SOF: ipc4-topology: Add support for core_id for pipelines
X-Git-Tag: v6.6.17~4901^2~8^2~157^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05ade472278a1a2fccc465ace205d6cfa9b521d5;p=platform%2Fkernel%2Flinux-rpi.git

ASoC: SOF: ipc4-topology: Add support for core_id for pipelines

Token SOF_TKN_SCHED_CORE in topology file can specify the target core for
the pipeline, if it is missing it is going to be 0 (as it is right now).

Firmware will double-check all information retrieved by topology and
report errors if required. This will allow policy and changes in
topologies without a need for a synchronized kernel change.
