Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> 2017-01-19selftest: cpufreq: Add support to test cpufreq modulesViresh Kumar3-6/+284 This patch adds support for cpufreq modules like cpufreq drivers and cpufreq governors. The tests will insert the modules in different orders and them perform basic cpufreq tests. The modules are then removed from the kernel.

It does basic tests for now, like - reading all cpufreq files - trying to update them - switching frequencies - switching governors This can be extended to have more specific tests later on.

The test requires patches to cpupower to pass correctly.

These changes bring the intel_pstate test inline with those changes.

This does not work after the following two changes. - 562e5f1a3: rework the "cpupower frequency-info" command (Jacob Tanenbaum) removed parsable limit output - ce512b840: Do not analyse offlined cpus (Thomas Renninger) added newline to break limit parsing more This change preserves human readable output if wanted as well as parsable output for scripts/tests.
