2025-12-08Documentation/gpu: Add documentation about ring bufferRodrigo Siqueira-0/+3506
AMDGPU heavily relies on ring buffers to manage its components; as a result, it has an elaborate mechanism of operation with multiple details around it. This commit introduces new documentation on ring buffers, detailing their management and expanding the explanation of Enforce isolation. Finally, this commit also adds the documentation available in the amdgpu_ring.c file to it.

2024-08-27drm/amd: Introduce additional IPS debug flagsLeo Li-1/+1
[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>
