drm/i915/display/vrr: Reset VRR capable property on a long hpd
With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings. When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit in the DPCD. Currently the driver parses that onevery HPD but fails to reset the corresponding VRR Capable Connector property. Hence the userspace still sees this as VRR Capable panel which is incorrect. Fix this by explicitly resetting the connector property. v2: Reset vrr capable if status == connector_disconnected v3: Use i915 and use bool vrr_capable (Jani Nikula) v4: Move vrr_capable to after update modes call (Jani N) Remove the redundant comment (Jan N) v5: Fixes the regression on older platforms by resetting the VRR only if HAS_VRR v6: Remove the checks from driver, add in drm core before setting VRR prop (Ville) v7: Move VRR set/reset to set/unset_edid (Ville) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Fixes: 9bc34b4d0f3c ("drm/i915/display/vrr: Reset VRR capable property on a long hpd") Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220303233222.4698-1-manasi.d.navare@intel.com (cherry picked from commit d999ad1079f574be06a8f1701cd24a5dc0ada48c) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
