The issue ended up being much more complicated however, as we also apparently needed to add support for an Intel-specific DPCD backlight control interface as the VESA interface is broken on many laptop panels. For lack of a better name, we just call this the Intel HDR backlight interface. While this only adds support for the SDR backlight mode (I think), this will fix a lot of user's laptop panels that we weren't able to properly automatically detect DPCD backlight controls on previously. Series-wide changes in v3: * Pass down brightness values to enable/disable backlight callbacks in a separate patch * Rebase Lyude Paul (4): drm/i915: Keep track of pwm-related backlight hooks separately drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now) drm/i915/dp: Allow forcing specific interfaces through enable_dpcd_backlight drm/dp: Revert "drm/dp: Introduce EDID-based quirks" drivers/gpu/drm/drm_dp_helper.c | 83 +--- drivers/gpu/drm/drm_dp_mst_topology.c | 3 +- .../drm/i915/display/intel_display_types.h | 14 +- drivers/gpu/drm/i915/display/intel_dp.c | 9 +- .../drm/i915/display/intel_dp_aux_backlight.c | 285 ++++++++++++-- drivers/gpu/drm/i915/display/intel_dp_mst.c | 3 +- drivers/gpu/drm/i915/display/intel_panel.c | 371 ++++++++++-------- drivers/gpu/drm/i915/display/intel_panel.h | 4 + drivers/gpu/drm/i915/display/intel_psr.c | 2 +- drivers/gpu/drm/i915/i915_params.c | 2 +- include/drm/drm_dp_helper.h | 21 +- 11 files changed, 503 insertions(+), 294 deletions(-) -- 2.29.2 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
