Can you elaborate on the need for a kernel module? It would be helpful
to know tne value the mdoule adds and why it is necessary. Include
details on why it can't be done as part of the user-space program.

I am not saying it isn't necssary, I would like to know the reasons
before I review the patch.

Also if this is a driver test, why not use other test frameworks
such as kunit or kselftest. cpupower is user-space utility and
driver debug code would not belong in here.
