From: Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx> I'd originally reported an i915 regression caused by a linux-stable backport, and then later posted an RFC fix for it: https://lore.kernel.org/linux-rt-users/ZJTuDi1HNp9L2zxY@xxxxxxxxxxxxx/ That eventually led to further discussion and an eventual fix from Tvrtko that Sebastian put into the v6.4-rt queue, which is great. However, the original regression was reported on v5.15-rt. This closes the loop by backporting the v6.4-rt change to v5.15-rt/v6.1-rt -- as it turns out, the same backport applies cleanly to both baselines. The only small change required is to fix up the context a bit in the 5th and final chunk, because kernel versions before v6.4 dont have the commit b7d70b8b06ed ("drm/i915/gsc: implement wa 14015076503") Paul. -- Cc: Clark Williams <williams@xxxxxxxxxx> [6.1-rt] Cc: Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx> [5.15-rt] --- Tvrtko Ursulin (1): drm/i915: Do not disable preemption for resets drivers/gpu/drm/i915/gt/intel_reset.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) -- 2.40.0
