selftests/amd-pstate: Added option to provide perf binary path

2023-10-16T19:06:58+00:00

In selftests/amd-pstate, distro `perf` is used to capture `perf stat` while running microbenchmarks. Distro `perf` is not working with upstream kernel. Fix this by providing an option to give the perf binary path. Reviewed-by: Mario Limonciello Signed-off-by: Swapnil Sapkal Signed-off-by: Shuah Khan

selftests/amd-pstate: Fix broken paths to run workloads in amd-pstate-ut

2023-10-16T19:06:50+00:00

In selftests/amd-pstate, tbench and gitsource microbenchmarks are used to compare the performance with different governors. In current implementation the relative path to run `amd_pstate_tracer.py` is broken. Fix this by using absolute paths.

selftests: amd-pstate: fix TEST_FILES

2023-03-07T00:03:20+00:00

Bring back the Python scripts that were initially added with TEST_GEN_FILES but now with TEST_FILES to avoid having them deleted when doing a clean. Also fix the way the architecture is being determined as they should also be installed when ARCH=x86_64 is provided explicitly. Then also append extra files to TEST_FILES and TEST_PROGS with += so they don't get discarded.

selftests: amd-pstate: Split basic.sh into run.sh and basic.sh.

2022-11-01T09:20:58+00:00

Split basic.sh into run.sh and basic.sh. The modification makes basic.sh more pure, just for test basic kernel functions. The file of run.sh mainly contains functions such as test entry, parameter check, prerequisite and log clearing etc. Then you can specify test case in kselftest/amd-pstate, for example: sudo ./run.sh -c basic.
