Subject: [x86/retpolines] a9d57ef15c: will-it-scale.per_process_ops -2.9%
regression
Greeting,
FYI, we noticed a -2.9% regression of will-it-scale.per_process_ops due to commit:
commit: a9d57ef15cbe327fe54416dd194ee0ea66ae53a4 ("x86/retpolines: Disable switch jump tables when retpolines are enabled")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.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: process
test: poll2
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
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------+
| testcase: change | will-it-scale: will-it-scale.per_process_ops 1.9% improvement |
| test machine | 104 threads Skylake with 192G memory |
| test parameters | cpufreq_governor=performance |
| | mode=process |
| | nr_task=100% |
| | test=poll2 |
+------------------+---------------------------------------------------------------+
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
