Subject: [PATCH V1 0/4] Add tbench/gitsource new test cases for amd-pstate-ut

Hi all:

The new patches are modified on the basis of the previous patch
https://lore.kernel.org/lkml/20220526034725.1708916-1-li.meng@amd.com/.

First, we modify amd-pstate-ut.sh to basic.sh as a basic test, mainly for
AMD P-State kernel drivers. The purpose of this modification is to facilitate
the subsequent addition of gitsource, tbench and other tests.
You can test specific functions by specifying test cases.
Default test all cases, include basic, tbench and gitsource etc.

Secondly, add tbench.sh trigger the tbench testing and monitor the cpu
information.
1) Download and install tbench codes.
2) Run tbench benchmark on specific governors, ondemand or schedutil.
3) Get desire performance, frequency, load by perf.
4) Get power consumption and throughput by amd_pstate_trace.py.
5) Analyse test results and save it in file selftest.tbench.csv. 

Third, add gitsource.sh trigger the gitsource testing and monitor the cpu
information.
1) Download and tar gitsource codes.
2) Run gitsource benchmark on specific governors, ondemand or schedutil.
3) Get desire performance, frequency, load by perf.
4) Get power consumption and throughput by amd_pstate_trace.py.
5) Get run time by /usr/bin/time.
6) Analyse test results and save it in file selftest.gitsource.csv. 

Finally, modify rst document to introduce test steps and results etc.

Thanks, 
Jasmine
