Greeting,
FYI, we noticed a -11.4% regression of will-it-scale.per_thread_ops due to commit:
commit: 332f22a60e4c3492d4953cd6f7aaa4e8bd0bba97 ("xdp: Remove map_to_flush and map
swap detection")
https://github.com/alaahl/linux.git for-upstream
in testcase: will-it-scale
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:
nr_task: 100%
mode: thread
test: dup1
cpufreq_governor: performance
ucode: 0x11
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel
copies to see if the testcase will scale. It builds both a process and threads based test
in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
If you fix the issue, kindly add following tag
