It seem that when dealing with VRR capable eDP panels we need to accept fixed modes with variable vblank length (which is what VRR varies dynamically). Typically the preferred mode seems to be a non-VRR more (lowish dotclock/refresh rate + short vblank). We also have examples where it looks like even the hblank length is a bit different between the preferred mode vs. VRR mode(s). So let's just accept anything that has matching hdisp+vdisp+flags. v2: Document that is_alt_drrs_mode() is a subset of is_alt_vrr_mode() (Jani) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/125 Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220531191844.11313-4-ville.syrjala@linux.intel.com
