Subject: [PATCH 1/2] selftests/amd-pstate: Fix broken paths to run workloads in amd-pstate-ut
In selftests/amd-pstate, tbench and gitsource microbenchmarks are used to
compare the performance with different governors. In Current
implementation relative path to run `amd_pstate_tracer.py`
broken. Fixed this by using absolute paths.
Also selftests/amd-pstate uses distro `perf` to capture stats while running
these microbenchmarks. Distro `perf` is not working with upstream
kernel. Fixed this by providing an option to give the perf binary path.
