Subject: Re: [RFC PATCH V1 2/6] sched/numa: Add disjoint vma unconditional
scan logic
Hello,
kernel test robot noticed a -11.9% improvement of autonuma-benchmark.numa01_THREAD_ALLOC.seconds on:
commit: 1ef5cbb92bdb320c5eb9fdee1a811d22ee9e19fe ("[RFC PATCH V1 2/6] sched/numa: Add disjoint vma unconditional scan logic")

patch subject: [RFC PATCH V1 2/6] sched/numa: Add disjoint vma unconditional scan logic
testcase: autonuma-benchmark
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory

test: numa01_THREAD_ALLOC
cpufreq_governor: performance
hi, Raghu,
the reason there is a separate report for this commit besides
https://lore.kernel.org/all/202309102311.84b42068-oliver.sang@intel.com/
is due to bisection nature, for one auto-bisect, we so far only could capture
one commit for performance change.
this auto-bisect is running on another test machine (Sapphire Rapids), and it
happened to choose autonuma-benchmark.numa01_THREAD_ALLOC.seconds as indicator
to do the bisect, it finally captured
"[RFC PATCH V1 2/6] sched/numa: Add disjoint vma unconditional"
and from
https://lore.kernel.org/all/acf254e9-0207-7030-131f-8a3f520c657b@amd.com/
I noticed you care more about the performance impact of whole patch set,
so let me give a summary table as below.
firstly, let me give out how we apply your patch again:
68cfe9439a1ba (linux-review/Raghavendra-K-T/sched-numa-Move-up-the-access-pid-reset-logic/20230829-141007) sched/numa: Allow scanning of shared VMAs
af46f3c9ca2d1 sched/numa: Allow recently accessed VMAs to be scanned
167773d1ddb5f sched/numa: Increase tasks' access history
fc769221b2306 sched/numa: Remove unconditional scan logic using mm numa_scan_seq
1ef5cbb92bdb3 sched/numa: Add disjoint vma unconditional scan logic
2a806eab1c2e1 sched/numa: Move up the access pid reset logic
2f88c8e802c8b (tip/sched/core) sched/eevdf/doc: Modify the documented knob to base_slice_ns as well
we have below data on this test machine
(full table will be very big, if you want it, please let me know):

it has some difference with our previous report on Ice Lake that
autonuma-benchmark.numa02.seconds seems keep stable,
but autonuma-benchmark.numa01.seconds has more changes.
anyway, for both platforms, we see performance improvement consistently
in this test along the patch-set.
Details are as below:

The kernel config and materials to reproduce are available at:
https://download.01.org/0day-ci/archive/20230912/202309121417.53f44ad6-oliver.sang@intel.com
below are normal data we shared in our performance reports. FYI.
(you won't see data for autonuma-benchmark.numa01.seconds or autonuma-benchmark.numa02.seconds,
since the delta bewteen 2a806eab1c and 1ef5cbb92b are small so our tool won't
show them)
