Subject: [cpuidle] 259231a045: will-it-scale.per_process_ops -12.6%
regression
Greeting,
FYI, we noticed a -12.6% regression of will-it-scale.per_process_ops due to commit:
commit: 259231a045616c4101d023a8f4dcc8379af265a6 ("cpuidle: add poll_limit_ns to cpuidle_device structure")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master
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: process
test: mmap1
cpufreq_governor: performance
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
