drm/amd: Introduce additional IPS debug flags

2024-08-27T21:51:32+00:00

[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 Reviewed-by: Aurabindo Pillai Signed-off-by: Alex Deucher

Documentation/amdgpu: Fix duplicate declaration

2024-07-16T15:45:22+00:00

Address the below kernel doc warning: Documentation/gpu/amdgpu/display/display-manager:134: drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:3: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/display/dcn-blocks:101. Declaration is '.. c:struct:: mpcc_blnd_cfg'. Documentation/gpu/amdgpu/display/display-manager:146: drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:3: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/display/dcn-blocks:3. Declaration is '.. c:enum:: mpcc_alpha_blend_mode'. To address the above warnings, this commit uses the 'no-identifiers' option in the dcn-blocks to avoid duplication with the previous use of this function doc in the display-manager file. Finally, replaces the deprecated ':function:' in favor of ':identifiers:'.

Documentation/gpu: Remove undocumented files from dcn-blockshubbub.h

The dchubbub.h and hubp.h do not have any meaningful documentation; for this reason, this commit removes those files from the dcn-blocks documentation. Cc: Alex Deucher Acked-by: Alex Deucher Reported-by: Stephen Rothwell Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

Documentation/gpu: Adjust DCN documentation paths

2024-07-16T15:45:02+00:00

When building the kernel-doc, it has the following complaints: Documentation/gpu/amdgpu/display/dcn-blocks:23: drivers/gpu/drm/amd/display/dc/inc/hw/hubp.h:3: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/display/dcn-blocks:3.

Declaration is '.. c:struct:: surface_flip_registers'. This error happened due to a copy-and-paste where the same file path was duplicated multiple times to a different set of blocks. This commit addresses this issue by using the correct file path. Cc: Alex Deucher Acked-by: Alex Deucher Reported-by: Stephen Rothwell Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

Documentation/gpu: Remove ':export:' option from DCN documentation

2024-07-16T15:44:56+00:00

This commit reduces, but does not fix, all the occurrences and some of the documentation warnings related to the 'no structured comments.' This was caused by the wrong use of the ':export:' option in the DCN kernel-doc, so this commit drops the usage of those options.

drm/amd/display: Move DIO documentation to the right place

2024-07-16T15:44:49+00:00

When building the kernel-doc, it complains with the below warning: ./drivers/gpu/drm/amd/display/dc/link/hwss/link_hwss_dio.h:1: warning: no structured comments found ./drivers/gpu/drm/amd/display/dc/link/hwss/link_hwss_dio.h:1: warning: no structured comments found This warning was caused by the wrong use of the ':export:' and the lack of function documentation in the file pointed under the ':internal:'. This commit addresses those issues by relocating the overview documentation to the correct C file, removing the ':export:' options, and adding two simple kernel-doc to ensure that ':internal:' does not have any warning.
