Subject: [PATCH 0/4 v0.5] sched/umcg: RFC UMCG patchset
Date: Wed, 8 Sep 2021 11:49:01 -0700 [thread overview]
Message-ID: <20210908184905.163787-1-posk@google.com> (raw)
This is an update on v0.4:
https://lore.kernel.org/lkml/20210801200617.623745-1-posk@google.com/
Key changes:
v0.3 => v0.4:
- made idle workers list logic simpler
- only one idle server tracking
- removed two fields from struct umcg_task
- added timeout handling
- added worker preemption
- added a doc patch that now documents the syscalls and state
transitions.
v0.4 => v0.5:
- refactored idle workers list management, as suggested by
Thierry Delisle here:
https://lore.kernel.org/lkml/3530714d-125b-e0f5-45b2-72695e2fc4ee@uwaterloo.ca/
I will now clean up libumcg (userspace) and selftests and post them
in a follow-up patchset.
