This set of patches is a continuation of DSC enablement patches for AMDGPU. This set enables DSC on MST. It also contains implementation of both encoder and connector atomic check routines.
These patches have been introduced in multiple iterations to the mailing list before. These patches were developed by David Francis as part of his work on DSC.
v2: squashed previously 3 separate atomic check patches, separate atomic check for dsc connectors, track vcpi and pbn on connectors.
v3: Moved modeset trigger on affected MST displays to DRM
v4: Fix warnings, use current mode's bpc rather than display's maximum capable one
v5: Moving branch's bandwidth validation to DRM, Added function to enable DSC per port in DRM
v6: Compute fair share uses DRM helper for BW validation
v7: Add helper to overwrite PBN divider per slot, Add helper function to trigger modeset on affected DSC connectors in DRM
v8: Rebased on top of the MST refactor patches that were on DRM-tip Some cosmetic and cleanup changes
David Francis (9): drm/dp_mst: Add PBN calculation for DSC modes drm/dp_mst: Parse FEC capability on MST ports drm/dp_mst: Add MST support to DP DPCD R/W functions drm/dp_mst: Fill branch->num_ports drm/dp_mst: Add helpers for MST DSC and virtual DPCD aux drm/amd/display: Initialize DSC PPS variables to 0 drm/amd/display: Validate DSC caps on MST endpoints drm/amd/display: Write DSC enable to MST DPCD drm/amd/display: MST DSC compute fair share
Mikita Lipski (8): drm/dp_mst: Add new quirk for Synaptics MST hubs drm/dp_mst: Manually overwrite PBN divider for calculating timeslots drm/dp_mst: Add DSC enablement helpers to DRM drm/dp_mst: Add branch bandwidth validation to MST atomic check drm/amd/display: Add PBN per slot calculation for DSC drm/amd/display: Recalculate VCPI slots for new DSC connectors drm/dp_mst: Add helper to trigger modeset on affected DSC MST CRTCs drm/amd/display: Trigger modesets on MST DSC connectors
