FYI, there is a patch for kunit_tool which will allow kernel
parameters to be passed through:
https://patchwork.kernel.org/project/linux-kselftest/patch/20210715160819.1107685-1-dlatypov@xxxxxxxxxx/

That being said, no-one's ever used any of the KUnit tooling for
performance testing before, as far as I know, so whether or not it
turns out to be useful or not remains to be seen. With this patch,
it'd at least be an option if you wanted to try it.
