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,
Felix
