Subject: [locking/rwsem] 46ad0840b1: reaim.jobs_per_min -3.4% regression
Greeting,
FYI, we noticed a -3.4% regression of reaim.jobs_per_min due to commit:
commit: 46ad0840b1584b92b5ff2cc3ed0b011dd6b8e0f1 ("locking/rwsem: Remove arch specific rwsem files")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git WIP.locking/core
in testcase: reaim
on test machine: 48 threads Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 100t
test: fork_test
cpufreq_governor: performance
ucode: 0x42d
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
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 run job.yaml
