Subject: [PATCH -V8 0/3] numa balancing: Migrate on fault among multiple bound nodes
Date: Wed, 6 Jan 2021 14:57:51 +0800 [thread overview]
Message-ID: <20210106065754.17955-1-ying.huang@intel.com> (raw)
To make it possible to optimize cross-socket memory accessing with
AutoNUMA even if the memory of the application is bound to multiple
NUMA nodes.
Patch [2/3] and [3/3] are NOT kernel patches. Instead, they are
patches for man-pages and numactl respectively. They are sent
together to make it easy to review the newly added kernel API.
Changes:
v8:
- Rebased on latest upstream kernel v5.11-rc2
v7:
- Make set_mempolicy() return -1 with errno is set to EINVAL if mode
isn't MPOL_BIND per Mel's comments. Revise document accordingly
too.
v6:
- Rebased on latest upstream kernel v5.10-rc5
- Added some benchmark data and example in patch description of [1/3]
- Rename AutoNUMA to NUMA Balancing
- Add patches to man-pages [2/3] and numactl [3/3]
v5:
- Remove mbind() support, because it's not clear that it's necessary.
v4:
- Use new flags instead of reuse MPOL_MF_LAZY.
v3:
- Rebased on latest upstream (v5.10-rc3)
- Revised the change log.
v2:
- Rebased on latest upstream (v5.10-rc1)
Best Regards,
Huang, Ying
