[Intel-gfx] [PATCH 1/4] drm/i915: Introduce intel_crtc_needs_fastset()

Ville Syrjala ville.syrjala at linux.intel.com
Thu Oct 20 12:04:54 UTC 2022


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Replace the somewhat obscure crtc_state.update_pipe checks
with a more descriptive thing. Also nicely matches the
intel_crtc_needs_modeset() counterpart for full modesets.
