Subject: [x86,sched] 8e663d38f1: reaim.jobs_per_min -2.1% regression
Greeting,
FYI, we noticed a -2.1% regression of reaim.jobs_per_min due to commit:
commit: 8e663d38f1ce6ed9151c949f952765dd24fbdb22 ("x86,sched: Add support for frequency invariance")
https://github.com/0day-ci/linux/commits/Giovanni-Gherdovich/Add-support-for-frequency-invariance-for-some-x86/20200124-181636
in testcase: reaim
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: compute
cpufreq_governor: performance
ucode: 0xb000038
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen@...el.com>
Details are as below:
