Subject: [x86/gart] ffc8599aa9: will-it-scale.per_thread_ops -1.3%
regression
Greeting,
FYI, we noticed a -1.3% regression of will-it-scale.per_thread_ops due to commit:
commit: ffc8599aa9763f39f6736a79da4d1575e7006f9a ("x86/gart: Exclude GART aperture from kcore")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_task: 100%
mode: thread
test: sched_yield
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_thread_ops -2.0% regression |
| test machine | 192 threads Skylake-SP with 256G memory |
| test parameters | cpufreq_governor=performance |
| | mode=thread |
| | nr_task=100% |
| | test=sched_yield |
+------------------+--------------------------------------------------------------+
If you fix the issue, kindly add following tag
