Subject: [lkp-robot] [kernel/kexec_file.c] b3ab44957a:
will-it-scale.per_thread_ops -3.4% regression
Greeting,
FYI, we noticed a -3.4% regression of will-it-scale.per_thread_ops due to commit:
commit: b3ab44957abf947983082240f1d46a91217debce ("kernel/kexec_file.c: add walk_system_ram_res_rev()")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: will-it-scale
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
nr_task: 50%
mode: thread
test: pread1
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
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
