Hello,
Here's is collection of patches addressing some stability issues.
The first patch has been submitted a while ago but was lacking a way
to kill in-flight jobs when a context is closed; which is now addressed
in patch 10.
The rest of those patches are improving fault handling (with some code
refactoring in the middle).
"drm/panfrost: Do the exception -> string translation using a table"
still has a TODO. I basically mapped all exception types to
EINVAL since most faults are triggered by invalid job/shaders, but
there might be some exceptions that should be translated to something
else. Any feedback on that aspect is welcome.
Regards,
Boris
