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) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
4) Get desire performance, frequency, load by perf.
5) Get power consumption and throughput by amd_pstate_trace.py.
6) Analyse test results and save it in file selftest.tbench.csv. 
7) Plot png images about performance, energy and performance per watt
for each test.

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) Run tbench benchmark comparative test on acpi-cpufreq kernel driver.
4) Get desire performance, frequency, load by perf.
5) Get power consumption and throughput by amd_pstate_trace.py.
6) Get run time by /usr/bin/time.
7) Analyse test results and save it in file selftest.gitsource.csv. 
8) Plot png images about time, energy and performance per watt
for each test.

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

See patch series in below git repo:
V1:https://lore.kernel.org/lkml/20220706073622.672135-1-li.meng@amd.com/

Changes from V1->V2:
- selftests: amd-pstate:
- - delete main.sh and merge funtions into run.sh
- selftests: amd-pstate:
- - modify ppw to performance per watt for tbench.
- - add comments for performance per watt for tbench.
- - add comparative test on acpi-cpufreq for tbench.
- - calculate drop between amd-pstate and acpi-cpufreq etc.
- - plot images about perfrmance,energy and ppw for tbench.
- selftests: amd-pstate:
- - modify ppw to performance per watt for gitsource.
- - add comments for performance per watt for gitsource.
- - add comparative test on acpi-cpufreq for gitsource.
- - calculate drop between amd-pstate and acpi-cpufreq etc.
- - plot images about perfrmance,energy and ppw for gitsource.
- Documentation: amd-pstate:
- - modify rst doc, introduce comparative test etc.

Thanks, 
Jasmine
