2025-10-28drm/amd/display: Add more DC HW state info to underflow loggingKaren Chen
[Why] Debugging underflow issues frequently requires knowing the HW state at the time of underflow. To enable capturing this HW state information, interface functions are needed for the various DC HW blocks. [How] This change adds the interface functions to read HW state for the following DC HW blocks: - HUBBUB - HUBP - DPP - MPC - OPP - DSC - OPTC - DCCG Reviewed-by: George Shen <george.shen@amd.com> Signed-off-by: Karen Chen <Karen.Chen@amd.com> Signed-off-by: Wayne Lin <wayne.lin@amd.com> Tested-by: Dan Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2025-07-15drm/amd/display: Refactor DSC cap calculationsDillon Varone
[WHY] DSC block level should only be responsible for reporting single DSC instance capabilities. Factoring in ODM combine requirements should be handled in dc_dsc.c. Both components should acquire clocks from clk_mgr to determine throughput capabilities instead of relying on hard coded values as these can differ by SoC and SKU. [HOW] 1) Add dsc_get_single_enc_caps to acquire single DSC instance capabilities (replacing dsc_get_enc_caps), factoring in DSCCLK 2) add build_dsc_enc_caps to combine single DSC instance capabilities 3) account for max pixel rate per pipe (DISPCLK) when calculating minimum slice count Reviewed-by: Wenjing Liu <wenjing.liu@amd.com> Signed-off-by: Dillon Varone <dillon.varone@amd.com> Signed-off-by: Ivan Lipski <ivan.lipski@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-05-05drm/amd/display: Refactoring DSC enum dsc_bits_per_comp.Bhuvanachandra Pinninti
[Why] Previously the 'dsc_bits_per_comp' enumeration was defined in individual .c files, making it unavailable for other files that may need it. [How] The 'dsc_bits_per_comp' enumeration has been relocated to a common header file.

2024-05-13drm/amd/display: Allow higher DSC slice support for small timings on dcn401Wenjing Liu
[WHY] DML2.1 has added the support to determine ODM combine based on DSC slice count limitation. This support would allow us to support DSC slice higher than 4 on small timings. The change will allow higher DSC slice support independent from pixel clock in use. [HOW] Add a DCN401 get_enc_caps function to allow the support for DSC slice count higher than 4.

2024-05-08drm/amd/display: reset DSC clock in post unlock updateWenjing Liu
[why] Switching between DSC clock or disable DSC block are not double buffered update. Corruption is observed if these updates happen before DSC double buffered disconnection. [how] Move DSC disable and refclk reset to post unlock update. Wait for DSC double buffered disconnection and all mpccs are disconnected before reset DSC clock.
