This patch set splits out static hdr metadata backlight range parsing from gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c into gpu/drm/drm-edid.c as a new function. This new function is then used during edid parsing when HDR static metadata block parsing. Calculated values are stored in a new struct drm_luminance_range introduced into display_info. Amdgpu_dm.c and intel_dp_aux_backlight.c are using this new data. v3: Some clean-ups suggested by Jani Nikula v2: Calculate the range during edid parsing and store into display_info Cc: Roman Li <roman.li@xxxxxxx> Cc: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Cc: Harry Wentland <harry.wentland@xxxxxxx> Cc: Lyude Paul <lyude@xxxxxxxxxx> Cc: Mika Kahola <mika.kahola@xxxxxxxxx> Cc: Jani Nikula <jani.nikula@xxxxxxxxx> Cc: Manasi Navare <manasi.d.navare@xxxxxxxxx> Jouni Högander (3): drm: New function to get luminance range based on static hdr metadata drm/amdgpu_dm: Rely on split out luminance calculation function drm/i915: Use luminance range calculated during edid parsing .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 35 ++----------- drivers/gpu/drm/drm_edid.c | 52 ++++++++++++++++++- .../drm/i915/display/intel_dp_aux_backlight.c | 15 +++++- include/drm/drm_connector.h | 21 ++++++++ 4 files changed, 89 insertions(+), 34 deletions(-) -- 2.25.1
