This commit adds a documentation page that discusses the programming model used by DCN and an overview of how the display code is organized.

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: 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.
