[Intel-gfx] [PATCH 4/9] drm/i915/gt: Convert callers to user per-gt pcode functions

Wed Apr 20 06:25:04 UTC 2022


Convert appropriate callers to use per-gt pcode functions. Callers using
pcode functions at "global scope", including *all* display functions are
not converted, they continue to use the legacy pcode interface.
