Subject: [mm] f11826446d: reaim.jobs_per_min 3.9% improvement
Greeting,
FYI, we noticed a 3.9% improvement of reaim.jobs_per_min due to commit:
commit: f11826446de4c3a65d56ad7ad250e4e17fb79d7c ("mm: don't include <linux/blkdev.h> in <linux/backing-dev.h>")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: reaim
on test machine: 144 threads 4 sockets Intel(R) Xeon(R) Gold 5318H CPU @ 2.50GHz with 128G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: new_dbase
cpufreq_governor: performance
ucode: 0x700001e
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------+
| testcase: change | reaim: reaim.jobs_per_min 1.0% improvement |
| test machine | 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory |
| test parameters | cpufreq_governor=performance |
| | nr_task=100% |
| | runtime=300s |
| | test=dbase |
| | ucode=0x5003006 |
+------------------+-------------------------------------------------------------------------------------+
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.
