* drm/amd: Duplicate DC_FEATURE_MASK and DC_DEBUG_MASK enum values into kdocMario Limonciello2025-09-151-32/+66
| | | | | | | | | | | | | | | [Why] When kernel documentation is generated the enum values themselves don't end up in the documentation. This makes browsing them in HTML a lot less useful. [How] Copy DC_DEBUG_MASK and DC_FEATURE_MASK enum values into matching kdoc comments.

* drm/amd: Introduce additional IPS debug flagsLeo Li2024-08-271-1/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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 <[email protected]> Reviewed-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
