[ANNOUNCE] PUCK Notes - 2023.07.19 - LPC and guest_memfd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I forgot to hit "record", so unfortunately there's no video evidence this time
around :-(

LPC:
 - Format will utilize flexible timeslots; tentatively planning on ~3 "big"
   slots of ~40 minutes each, and ~6 "small" slots of 10-15 minutes each.
 - Schedule will be announced around September 15th (though that may get pushed
   backed to October 1st).
 - Schedule is flexibile up until the conference, e.g. if code is merged between
   September 15th and early November and obviates the need for a discussion.

guest_memfd:
 Topic Branch:
   - Work will be coordinated through a dedicated topic branch (likely
     kvm-x86/guest_memfd).
   - Mostly stable branch; plan is to not rebase it for at least the next month
   - Fixes (use Fixes: tag!!!) will be applied on top and squashed when the
     branch is rebased.
   - TBD will post a series for broader review in a month or so once
     development has settled down.

  - Documentation [Sean?]
  - Changelogs [Sean]
  - Non-filemap implementation [Paolo]
