SubjectRe: BoF at LPC: Documenting the Heterogeneous Memory Model Architecture
From
Date
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
