Subject: [PATCH 0/5] cgroup/cpuset: Enable cpuset partition with no load balancing
Date: Thu, 3 Jun 2021 17:24:11 -0400 [thread overview]
Message-ID: <20210603212416.25934-1-longman@redhat.com> (raw)
This patchset makes the following two major changes to the cpuset v2 code:
Patch 2: Add a new partition state "root-nolb" to create a partition
root with load balancing disabled. This is for handling intermitten
workloads that have a strict low latency requirement.
Patch 3: Allow partition roots that are not the top cpuset to distribute
all its cpus to child partitions as long as there is no task associated
with that partition root. This allows more flexibility for middleware
to manage multiple partitions.
Patch 4 updates the cgroup-v2.rst file accordingly. Patch 5 adds a test
to test the new cpuset partition code.
Waiman Long (5):
cgroup/cpuset: Don't call validate_change() for some flag changes
cgroup/cpuset: Add new cpus.partition type with no load balancing
cgroup/cpuset: Allow non-top parent partition root to distribute out
all CPUs
cgroup/cpuset: Update description of cpuset.cpus.partition in
cgroup-v2.rst
kselftest/cgroup: Add cpuset v2 partition root state test
