This reverts commit 9e31c1fe45d555a948ff66f1f0e3fe1f83ca63f7. Ever since that commit, we've been having issues where a hang in one client
Hmm. Sounds like problem I'm seeing in mainline. So... good to know.
For backporters: Please note that you _must_ have a backport of https://lore.kernel.org/dri-devel/20210602164149.391653-2-jason@jlekstrand.n... for otherwise backporting just this patch opens up a security bug.
AFAICT we don't have that c9d9fdbc108af8915d3f497bbdf3898bf8f321b8 drm/i915: Revert "drm/i915/gem: Asynchronous cmdparser" in 5.10 tree.
Hmm, and it needs follow up fix: 6e0b6528d783b2b87bd9e1bea97cf4dac87540d7 drm/i915: Correct the docs for intel_engine_cmd_parser.
(Someone please double check this).
thanks, let me drop this for now.
Jason, you sent me a single patch to backport, should this be 3 patches instead?
thanks,
