Subject: [GIT PULL] Scheduler changes for v6.8
Date: Mon, 8 Jan 2024 15:07:07 +0100 [thread overview]
Message-ID: <ZZwBi/YmnMqm7zrO@gmail.com> (raw)
In-Reply-To: ZTz9RpZxfxysYCmt@gmail.com
Linus,
Please pull the latest sched/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-2024-01-08
# HEAD: cdb3033e191fd03da2d7da23b9cd448dfa180a8e Merge branch 'sched/urgent' into sched/core, to pick up pending v6.7 fixes for the v6.8 merge window
Scheduler changes for v6.8:
- Energy scheduling:
- Consolidate how the max compute capacity is
used in the scheduler and how we calculate
the frequency for a level of utilization.
- Rework interface between the scheduler and
the schedutil governor
- Simplify the util_est logic
- Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE
starvation of low priority tasks (e.g., SCHED_OTHER)
tasks when higher priority tasks monopolize CPU
cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are
not introduced yet.
- EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
- NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more,
to better distribute the probability
of a particular vma getting scanned.
- Plus misc fixes, cleanups and updates.
Thanks,
Ingo
