Hello,
Bunch of improvements to make the panfrost driver more robust and allow queuing jobs at the HW level.
Changes in v6:
- Collected acks/reviews
- Got rid of the cancel_delayed_work() calls in the reset path
Changes in this v5:
- Document what's excepted in the ->timedout_job() hook
- Add a patch increasing the AS_ACTIVE polling timeout
- Fix a few minor things here and there (see each commit for a detailed changelog) and collect R-b/A-b tags
Changes in this v4:
- fixing the reset serialization
- fixing a deadlock in the reset path
- moving the exception enum to a private header
Regards,
Boris
