Subject: [sched/fair] 8b4e74ccb5: stress-ng.sem.ops_per_sec 12.0%
improvement
Greeting,
FYI, we noticed a 12.0% improvement of stress-ng.sem.ops_per_sec due to commit:
commit: 8b4e74ccb582797f6f0b0a50372ebd9fd2372a27 ("sched/fair: Fix detection of per-CPU kthreads waking a task")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 100%
testtime: 60s
sc_pid_max: 4194304
class: scheduler
test: sem
cpufreq_governor: performance
ucode: 0x5003102
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo 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
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
