I started sketching some reworks there, but that got put on the backburner due to other stuff: https://github.com/vsyrjala/linux.git scaler_rework_2 I might have somehting more recent than that locally, but I'd have to trawl through my branches to check what's the latest state. > > Cc: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> > Cc: Matt Roper <matthew.d.roper@xxxxxxxxx> > Cc: Dongwon Kim <dongwon.kim@xxxxxxxxx> > > Vivek Kasireddy (3): > drm/i915: Rename skl_pfit_enable() to skl_program_crtc_scaler() > drm/i915: Attach the Border property to DP and HDMI connectors > drm/i915: Apply border adjustments and enable scaler on the crtc > > drivers/gpu/drm/i915/display/intel_atomic.c | 29 ++++++++++- > .../gpu/drm/i915/display/intel_connector.c | 49 +++++++++++++++++++ > .../gpu/drm/i915/display/intel_connector.h | 3 ++ > drivers/gpu/drm/i915/display/intel_display.c | 25 ++++++++-- > .../gpu/drm/i915/display/intel_display_core.h | 1 + > .../drm/i915/display/intel_display_types.h | 6 +++ > drivers/gpu/drm/i915/display/intel_dp.c | 11 +++++ > drivers/gpu/drm/i915/display/intel_hdmi.c | 11 +++++ > drivers/gpu/drm/i915/display/skl_scaler.c | 27 ++++++---- > drivers/gpu/drm/i915/display/skl_scaler.h | 3 +- > 10 files changed, 149 insertions(+), 16 deletions(-) > > -- > 2.43.0 -- Ville Syrjälä Intel
