It could import as a module to launch some test tasks. We upstream out AMD P-state driver into Linux kernel and use this unit test module to verify the required conditions and basic functions of amd-pstate before integration test. We use test module in the kselftest frameworks to implement it. We create amd_pstate_testmod module and tie it into kselftest. For exmaple: The test case aput_acpi_cpc is used to check whether the _CPC object is exist in SBIOS. The amd-pstate initialization will fail if the _CPC in ACPI SBIOS is not existed at the detected processor, so it is a necessary condition. At present, its test cases are very simple, and the corresponding test cases will continue to be added later to improve the test coverage. See patch series in below git repo: V1: https://lore.kernel.org/linux-pm/20220323071502.2674156-1-li.meng@amd.com/ Changes from V1 -> V2: - cpufreq: amd-pstate: - - add a trailing of amd-pstate.h to MAINTAINER AMD PSTATE DRIVER - selftests: cpufreq - - add a wrapper shell script for the amd_pstate_testmod module - selftests: cpufreq: - - remove amd_pstate_testmod kernel module to .../cpufreq/amd_pstate_testmod - Documentation: amd-pstate: - - amd_pstate_testmod rst document is not provided at present.
