[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 <jun.lei@amd.com> Signed-off-by: Jerry Zuo <jerry.zuo@amd.com> Signed-off-by: Samson Tam <samson.tam@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2024-07-16drm/amd/display: Move DIO documentation to the right placeRodrigo Siqueira
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.
