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.
