First fix patch is taken from : https://patchwork.freedesktop.org/series/122613/ Adding here to to avoid issues while reading fractional bpp support. The new few patches, add changes to accommodate compressed bpp with fractional part, including changes to QP calculations. To get the 'best' compressed bpp, we iterate over the valid compressed bpp values, but with fractional step size 1/16, 1/8, 1/4 or 1/2 as per sink support. The last 2 patches add support to depict DSC sink's fractional support, and debugfs to enforce use of fractional bpp, while choosing an appropriate compressed bpp. Ankit Nautiyal (6): drm/display/dp: Fix the DP DSC Receiver cap size drm/i915/display: Store compressed bpp in U6.4 format drm/i915/display: Consider fractional vdsc bpp while computing m_n values drm/i915/audio : Consider fractional vdsc bpp while computing tu_data drm/display/dp: Add helper function to get DSC bpp prescision drm/i915/dp: Iterate over output bpp with fractional step size Swati Sharma (2): drm/i915/dsc: Add debugfs entry to validate DSC fractional bpp drm/i915/dsc: Allow DSC only with fractional bpp when forced from debugfs Vandita Kulkarni (1): drm/i915/dsc/mtl: Add support for fractional bpp drivers/gpu/drm/display/drm_dp_helper.c | 27 ++++++ drivers/gpu/drm/i915/display/icl_dsi.c | 10 +-- drivers/gpu/drm/i915/display/intel_audio.c | 14 ++-- drivers/gpu/drm/i915/display/intel_bios.c | 2 +- drivers/gpu/drm/i915/display/intel_display.c | 6 +- drivers/gpu/drm/i915/display/intel_display.h | 2 +- .../drm/i915/display/intel_display_debugfs.c | 82 +++++++++++++++++++ .../drm/i915/display/intel_display_types.h | 17 +++- drivers/gpu/drm/i915/display/intel_dp.c | 68 +++++++++------ drivers/gpu/drm/i915/display/intel_dp_mst.c | 6 +- drivers/gpu/drm/i915/display/intel_fdi.c | 2 +- .../gpu/drm/i915/display/intel_qp_tables.c | 3 - drivers/gpu/drm/i915/display/intel_vdsc.c | 27 ++++-- include/drm/display/drm_dp.h | 2 +- include/drm/display/drm_dp_helper.h | 1 + 15 files changed, 216 insertions(+), 53 deletions(-)
