From 824df77ab2107d8d4740b834b276681a41ae1ac8 Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Tue, 25 Jul 2023 02:19:48 +0200 Subject: 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.
