Hi all:
AMD P-State unit test(amd-pstate-ut) is a kernel module for testing the functions of amd-pstate. 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.
When you test all the test cases, you will get the following test results. The status "P" is pass, "F" is fail. jasmine@jasmine:/sys/module/amd_pstate_ut/parameters$ cat unit_test Index Test cases Status 0 stop [ ] 1 all [P] 2 x86_vendor [P] 3 acpi_cpc_valid [P] 4 modprobed_driver [P] 5 capability_check [P] 6 enable [P] 7 init_perf [P] 8 support_boost [P] 9 clear_status [ ] ------------------------------------------ begin_index = 1 end_index= 8
For exmaple: The test case acpi_cpc_valid 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.
Thanks, Jasmine
