[Why] Idle power states (IPS) describe levels of power-gating within DCN. DM and DC is responsible for ensuring that we are out of IPS before any DCN programming happens. Any DCN programming while we're in IPS leads to undefined behavior (mostly hangs). Because IPS intersects with all display features, the ability to disable IPS by default while ironing out the known issues is desired. However, disabing it completely will cause important features such as s0ix entry to fail. Therefore, more granular IPS debug flags are desired. [How] Extend the dc debug mask bits to include the available list of IPS debug flags. All the flags should work as documented, with the exception of IPS_DISABLE_DYNAMIC. It requires dm changes which will be done in later changes. v2: enable docs and fix docstring format Signed-off-by: Leo Li <sunpeng.li@amd.com> Reviewed-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
