Subject: [clocksource] 8c4b798316: stress-ng.lockbus.ops_per_sec -8.5%
regression
Greeting,
FYI, we noticed a -8.5% regression of stress-ng.lockbus.ops_per_sec due to commit:
commit: 8c4b798316c77d18b351a36e3660e412de762d79 ("clocksource: Retry clock read if long delays detected")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 60s
class: cpu-cache
test: lockbus
cpufreq_governor: performance
ucode: 0x5003006
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
bin/lkp run generated-yaml-file
