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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
