Change of plan: Instead of a BoF, this is now a session in the "GPU/media/AI buffer management and interop MC" micro conference. Thank you Daniel Stone for making that happen. https://linuxplumbersconf.org/event/11/contributions/1112/
It is scheduled for tomorrow (Friday) 08:40-10:00 Pacific, 11:40-13:00 Eastern, 15:40-17:00 UTC.
I hope to see you all tomorrow, Felix
