Subject: Re: [RFC PATCH V1 4/6] sched/numa: Increase tasks' access history
hi, Raghu,
hope this third performance report for same one patch-set won't annoy you,
and better, have some value to you.
we won't send more autonuma-benchmark performance improvement reports for this
patch-set, of course, unless you still hope we do.
BTW, we will still send out performance/function regression reports if any.
as in previous reports, we know that you want to see the performance impact
of whole patch set, so let me give a full summary here:
let me list how we apply your patch set 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 <-- we reported [1]
167773d1ddb5f sched/numa: Increase tasks' access history <---- for this report
fc769221b2306 sched/numa: Remove unconditional scan logic using mm numa_scan_seq
1ef5cbb92bdb3 sched/numa: Add disjoint vma unconditional scan logic <--- we reported [2]
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
[1] https://lore.kernel.org/all/202309102311.84b42068-oliver.sang@intel.com/
[2] https://lore.kernel.org/all/202309121417.53f44ad6-oliver.sang@intel.com/
below will only give out the comparison between 2f88c8e802c8b and 68cfe9439a1ba
in a summary way, if you want detail data for more commits, or more comparison
data, please let me know. Thanks!
