Greeting,

There is no primary kpi change in this test, below is the data collected through multiple monitors running background just for your information.


commit: 7d758af257bc40a8a599a0aaa4768b30fb463e9c ("selftests: add default rules for c source file")
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master

in testcase: kernel_selftests
on test machine: qemu-system-x86_64 -enable-kvm -cpu host -smp 4 -m 5G
with following parameters:


test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
