Re: [PATCH v2 16/26] selftests/resctrl: Open perf fd before start & add error handling

Hi Ilpo,

Perf fd (pe_fd) is opened, reset, and enabled during every test the CAT selftest runs. Also, ioctl(pe_fd, ...) calls are not error checked even if ioctl() could return an error.

Open perf fd only once before the tests and only reset and enable the counter within the test loop. Add error checking to pe_fd ioctl() calls.
