selftests: amd-pstate: fix TEST_FILES

2023-03-22T12:37:41Z

[ Upstream commit 2da789cda462bda93679f53ee38f9aa2309d47e8 ] 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: Trigger gitsource benchmark and test cpus

2022-11-01T09:22:37Z

Add gitsource.sh trigger the gitsource testing and monitor the cpu desire performance, frequency, load, power consumption and throughput etc. 1) Download and tar gitsource codes. 2) Run gitsource benchmark on specific governors, ondemand or schedutil. 3) Run tbench benchmark comparative test on acpi-cpufreq kernel driver. 4) Get desire performance, frequency, load by perf. 5) Get power consumption and throughput by amd_pstate_trace.py. 6) Get run time by /usr/bin/time. 7) Analyse test results and save it in file selftest.gitsource.csv. 8) Plot png images about time, energy and performance per watt for each test.

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

2022-11-01T09:20:58Z

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. The detail please run the below script. ./run.sh --help Signed-off-by: Meng Li Acked-by: Huang Rui Signed-off-by: Shuah Khan

selftests: amd-pstate: Rename amd-pstate-ut.sh to basic.sh.

2022-11-01T09:20:51Z

Rename amd-pstate-ut.sh to basic.sh. The purpose of this modification is to facilitate the subsequent addition of gitsource, tbench and other tests. Signed-off-by: Meng Li Signed-off-by: Shuah Khan

cpufreq: amd-pstate: Add explanation for X86_AMD_PSTATE_UT

2022-10-05T17:05:18Z

This kernel module is used for testing. It's safe to say M here. It can also be built-in without X86_AMD_PSTATE enabled. Currently, only tests for amd-pstate are supported. If X86_AMD_PSTATE is set disabled, it can tell the users test can only run on amd-pstate driver, please set X86_AMD_PSTATE enabled. In the future, comparison tests will be added. It can set amd-pstate disabled and set acpi-cpufreq enabled to run test cases, then compare the test results.
