drm/amd/display: quality improvements for EASF and ISHARP

2024-07-23T21:07:09+00:00

[Why] Update coefficients and LUT tables for scaler and sharpener to improve quality and support different use cases (SDR/HDR) [How] Move scaler coefficients to new file dc_spl_scl_easf_filters.c Remove older coefficients file dc_sp_scl_filters_old.c Update default taps for EASF support Update LLS policy for DON'T CARE case Update cositing offset from 0.5 to 0.25 Add support to adjust sharpness based on level, use case, and scaling ratio ( using discrete levels ) Apply sharpness to all RGB surfaces and both NV12 and P010 video ( in fullscreen only ). Upscale and 1:1 ratios only Enable scaler when sharpening 1:1 ratios Add support for coefficients that are in S1.10 format (convert to S1.12 format) Reviewed-by: Jun Lei Signed-off-by: Jerry Zuo Signed-off-by: Samson Tam Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: adjust flow for deallocation mst payload

2023-11-29T21:49:00+00:00

[Why] MST relevant variables are maintained at drm side. As the result, we still have to call drm_dp_remove_payload_part2() to update the relevant values regardless the link is under mst mode or not. We used to have a workaround patch to tackle this: commit 3d8fcc6740c9 ("drm/amd/display: Extract temp drm mst deallocation wa into its own function") Now it's time to remove the workaround and adjust the flow. [How] During deallocate_mst_payload(), source actually doesn't send out ALLOCATE_PAYLOAD at the end as like the flow in allocate_mst_payload(). Call function dm_helpers_dp_mst_send_payload_allocation() at the end of deallocate_mst_payload() is a bit confusing. Separate dm_helpers_dp_mst_send_payload_allocation() into 2 functions. Have a new function dm_helpers_dp_mst_update_mst_mgr_for_deallocation() to replace dm_helpers_dp_mst_send_payload_allocation() for payload deallocation.

drm/amd/display: Only update link settings after successful MST link train

2022-11-09T22:41:41+00:00

[WHY] Currently driver reduces verified link caps on DPIA devices if a link is trained at a link rate below the max rate verified during link detection. This blocks high bandwidth modes after setting a low bandwidth mode. [HOW] Only update link rate after a successful link train if link is MST.
