From: Mikita Lipski <mikita.lipski@xxxxxxx> Patches are based of amd-staging-drm-next, the follow up set of patches will be sent for drm-tip 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. First 10 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 David Francis (10): 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 drm/dp_mst: Add new quirk for Synaptics MST hubs Mikita Lipski (3): drm/dp_mst: Add DSC enablement helpers to DRM drm/dp_mst: Add branch bandwidth validation to MST atomic check drm/amd/display: Recalculate VCPI slots for new DSC connectors .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 62 ++- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 3 + .../amd/display/amdgpu_dm/amdgpu_dm_helpers.c | 19 +- .../display/amdgpu_dm/amdgpu_dm_mst_types.c | 428 +++++++++++++++++- .../display/amdgpu_dm/amdgpu_dm_mst_types.h | 5 + .../drm/amd/display/dc/core/dc_link_hwss.c | 3 + .../gpu/drm/amd/display/dc/dcn20/dcn20_dsc.c | 3 + .../drm/amd/display/dc/dcn20/dcn20_resource.c | 3 + .../drm/amd/display/dc/dcn20/dcn20_resource.h | 1 + drivers/gpu/drm/drm_dp_aux_dev.c | 12 +- drivers/gpu/drm/drm_dp_helper.c | 33 +- drivers/gpu/drm/drm_dp_mst_topology.c | 318 ++++++++++++- drivers/gpu/drm/i915/display/intel_dp_mst.c | 3 +- drivers/gpu/drm/nouveau/dispnv50/disp.c | 3 +- drivers/gpu/drm/radeon/radeon_dp_mst.c | 2 +- include/drm/drm_dp_helper.h | 7 + include/drm/drm_dp_mst_helper.h | 14 +- 17 files changed, 879 insertions(+), 40 deletions(-) -- 2.17.1 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
