[PATCH v2 0/2] drm/panfrost: Queue jobs on the hardware

[Boris Brezillon]

Hello,

I'm resubmitting a patch submitted by Steven a long time ago. Not much
has changed except I realized I'd have to deal with soft-stops to
prevent this HW job queuing feature from killing innocent jobs when
a GPU hang happens. If we don't do that and a non-faulty job was in
progress when the GPU is reset, job headers might end up in an
inconsistent state, preventing them from being re-submitted after
the reset.

Also added an extra patch to use a threaded interrupt for job events
to avoid unneeded interrupt-context switches when short jobs are
queued.

Regards,

Boris
