The "CPU frequency scaling tests" item of FWTS.

[Huang, Bryan]

Hi Alex and FWTS members,

Here is TPE HPE Bryan Huang.
We tried to run the "CPU frequency scaling tests" of FWTS and encountered the following issue.

So we used the "Processors are set to SW_ANY." string to search the FWTS code.
We find the cpufreq_test_sw_any function to test the item.
The function will set all processor to their lowest speed first, and then set all processor to their highest speed.
Finally, the function will set all processor to their lowest speed again.

It seems that "if ((high_perf > newhigh_perf) && (high_perf - newhigh_perf > (high_perf - low_perf)/4) && (high_perf - low_perf > 20))" is satisfied, so the variable ok will be set to false.
Do you have any suggestions for the issue?

Please refer to the following information.

File location: src\cpu\cpufreq\cpufreq.c

Thanks.
