    Subject[PATCH 00/39] [RFC] AutoNUMA alpha10
    Date
    Hi everyone,

    This is the result of the first round of cleanups of the AutoNUMA patch.

    This can also be fetched through an autonuma-alpha10 branch.

    git clone --reference linux -b autonuma-alpha10 git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git

    A first attempt for an highlevel description of how this works can be
    found in the comment of the patch "autonuma: core".

    Some benchmark results can be found in the below document (updated to
    include the SMT regression test, with only half of the cores loaded,
    and half idle, page 7).

    Page 9 measures the overhead of the knuma_scand pass during a kernel
    build with its default 10sec knuma_scand pass interval.

    TODO:

    1) THP native migration
    2) dynamically allocate the AutoNUMA struct page fields like memcg
    does it so they won't take any memory if the kernel is booted on
    not-NUMA hardware
    3) write Documentation/vm/autonuma.txt with a kernel internal focus
    4) possibly find a way to improve the kernel/sched/numa.c algorithm
    with an implementation that is more integrated in CFS

    autonuma: knuma_migrated per NUMA node queues
    autonuma: init knuma_migrated queues
    autonuma: autonuma_enter/exit
    autonuma: call autonuma_setup_new_exec()
    autonuma: alloc/free/init sched_autonuma

    mm: add unlikely to the mm allocation failure check
    autonuma: avoid CFS select_task_rq_fair to return -1
    autonuma: select_task_rq_fair cleanup new_cpu < 0 fix
    autonuma: teach CFS about autonuma affinity
    autonuma: select_idle_sibling cleanup target assignment
    autonuma: core
    autonuma: follow_page check for pte_numa/pmd_numa
    autonuma: default mempolicy follow AutoNUMA
    autonuma: call autonuma_split_huge_page()
    autonuma: make khugepaged pte_numa aware
    autonuma: retain page last_nid information in khugepaged
    autonuma: numa hinting page faults entry points
    autonuma: reset autonuma page data when pages are freed
    autonuma: initialize page structure fields
    autonuma: link mm/autonuma.o and kernel/sched/numa.o
