Add .fence_priority_display() to display parent interface, removing a display dependency on gem/i915_gem_object.h. This allows us to remove the xe compat gem/i915_gem_object.h. v2: Don't mix this with the rps interface (Ville) v3: Rebase Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patch.msgid.link/c7782862956e3aa59eaeb6dcf80906c1fc063ae1.1763370931.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
