This patchset moves the DSC DPCD capabilities from the encoder (intel_dp) to the connector. This is required since in an MST topology each connector has its own version of these capabilities, allowing to configure/enable the DSC decompression for each stream separately. The changes are needed for a follow-up patchset, fixing the MST DSC functionality, making it also possible to enable the BW management on MST links. The follow-up changes are based on patches 12-25 in https://lore.kernel.org/all/20230914192659.757475-1-imre.deak@xxxxxxxxx Imre Deak (19): drm/i915/dp: Sanitize DPCD revision check in intel_dp_get_dsc_sink_cap() drm/i915/dp: Store DSC DPCD capabilities in the connector drm/i915/dp_mst: Set connector DSC capabilities and decompression AUX drm/i915/dp: Use i915/intel connector local variables in i915_dsc_fec_support_show() drm/i915/dp: Use connector DSC DPCD in i915_dsc_fec_support_show() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_compute_max_bpp() drm/i915/dp: Use connector DSC DPCD in intel_dp_supports_fec() drm/i915/dp: Use connector DSC DPCD in intel_dp_supports_dsc() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_max_sink_compressed_bppx16() drm/i915/dp: Pass connector DSC DPCD to drm_dp_dsc_sink_supported_input_bpcs() drm/i915/dp: Pass only the required i915 to intel_dp_source_dsc_version_minor() drm/i915/dp: Pass only the required DSC DPCD to intel_dp_sink_dsc_version_minor() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_compute_params() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_supports_format() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_get_slice_count() drm/i915/dp: Use connector DSC DPCD in intel_dp_mode_valid() drm/i915/dp: Use connector DSC DPCD in intel_dp_dsc_compute_config() drm/i915/dp_mst: Use connector DSC DPCD in intel_dp_mst_mode_valid_ctx() drm/i915/dp: Remove unused DSC caps from intel_dp .../drm/i915/display/intel_display_debugfs.c | 22 +-- .../drm/i915/display/intel_display_types.h | 8 +- drivers/gpu/drm/i915/display/intel_dp.c | 154 ++++++++++-------- drivers/gpu/drm/i915/display/intel_dp.h | 8 +- drivers/gpu/drm/i915/display/intel_dp_mst.c | 35 +++- 5 files changed, 136 insertions(+), 91 deletions(-) -- 2.39.2
