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

As the programming models for GPU-based high-performance computing 
applications are evolving, HMM is helping us integrate the GPU memory 
management more closely with the kernel's virtual memory management. 
As a result we can provide a shared virtual address space with 
demand-paging and page-based migrations of anonymous pages to/from 
device memory. A patch series by AMD [1, 2] to add support for 
cache-coherent, CPU-accessible device memory has brought up some 
fairly fundamental questions about HMM and its interaction with 
virtual memory management, page cache and file systems. We'd like to 
use the chance of getting together for a BoF [3] at LPC to raise 
awareness for HMM outside the GPU driver code, identify gaps in the 
architectural documentation and clarify our priorities for future 
development.

Thank you, Daniel, for suggesting the BoF and getting it scheduled. 
It's set for Friday, 10am Pacific, 1pm Eastern, 5pm UTC.

I am registered at LPC. Daniel got a speaker's pass. We're still 
trying to work something out for Alex.

I hope to see many of you on Friday.

Best regards,
