Evan Quan be68d44bf8 drm/amd/pm: fix runpm hang when amdgpu loaded prior to sound driver ... Current RUNPM mechanism relies on PMFW to master the timing for BACO in/exit. And that needs cooperation from sound driver for dstate change notification for function 1(audio). Otherwise(on sound driver missing), BACO cannot be kicked in correctly and hang will be observed on RUNPM exit. By switching back to legacy message way on sound driver missing, we are able to fix the runpm hang observed for the scenario below: amdgpu driver loaded -> runpm suspend kicked -> sound driver loaded Signed-off-by: Evan Quan <evan.quan@amd.com> Reported-and-tested-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Guchun Chen <guchun.chen@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>		2021-09-23 15:17:28 -04:00
