Ah, wait, I found the tarball you sent for these, and have taken them
for 5.4, 5.10, and 5.15 now (the original broke the build.) We still
need them for older kernels though, that's still an issue.
Thanks for applying patches.
Older kernels ( < 5.4) do not have the patch to fix ("drm/i915: Flush TLBs
before releasing backing store"), and they do not support Gen12 AFAIK,
so it should be fine.
The Fixes: tag in this commit references a commit that has been
backported into a lot of older kernels:
git id: '7938d61591d33394a21bdd7797a245b65428f44c' is in: 4.4.301 4.9.299 4.14.264 4.19.227 5.4.175 5.10.95 5.15.18 5.16.4 5.17
So is the Fixes tag incorrect?
My fault, they do contain the patch, and I was just looking by code path.
Anyway backports for kernel below 5.4 do not contain gen12 part so they
are fine - the bug was only in gen12.
