From: Mikita Lipski <mikita.lipski@xxxxxxx>
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
