Hello,
Sorry for the noise, but I forgot 2 fixes (one fixing the error set to the sched fence when the driver fence allocation fails, and the other one shrinking the dma signalling section to get rid of spurious lockdep warnings).
The rest of the series hasn't changed.
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
