Subject: [tip:x86/mm] [x86/kasan] 9fd429c280:
phoronix-test-suite.darktable.Masskrug.CPU-only.seconds -7.0% improvement
Greeting,
FYI, we noticed a -7.0% improvement of phoronix-test-suite.darktable.Masskrug.CPU-only.seconds due to commit:
commit: 9fd429c28073fa40f5465cd6e4769a0af80bf398 ("x86/kasan: Map shadow for percpu pages on demand")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git x86/mm
in testcase: phoronix-test-suite
on test machine: 12 threads 1 sockets Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz (Coffee Lake) with 16G memory
with following parameters:
test: darktable-1.0.5
option_a: Masskrug
option_b: CPU-only
cpufreq_governor: performance
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.
test-url: http://www.phoronix-test-suite.com/
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.
