Subject: [PATCH] drm/i915/gt: Enable the CCS_FLUSH bit in the pipe control and
in the CS
Enable the CCS_FLUSH bit 13 in the control pipe for render and
compute engines in platforms starting from Meteor Lake (BSPEC
43904 and 47112).
For the copy engine add MI_FLUSH_DW_CCS (bit 16) in the command
streamer.
Fixes: 972282c4cf24 ("drm/i915/gen12: Add aux table invalidate for all engines")
Requires: 8da173db894a ("drm/i915/gt: Rename flags with bit_group_X according to the datasheet")
