+
+ Test and monitor the cpu changes when running tbench benchmark under the specified governor.
+ These changes include desire performance, frequency, load, performance, energy etc.
+ The specified governor is ondemand or schedutil.
+ Tbench can also be tested on the acpi-cpufreq kernel driver for comparison.

#. How to execute the tests
We use test module in the kselftest frameworks to implement it.
We create amd-pstate-ut module and tie it into kselftest.(for
details refer to Linux Kernel Selftests [4]_).

let's align the same format in this document.
acpi-cpufreq -> ``acpi-cpufreq``
amd-pstate-ut -> ``amd-pstate-ut``
Others look good for me.
