[Bug 1005829] Re: Power Management LAVA test failed on "checking 'ondemand' directory exists".
Hongbo, why do you think this is not a PM-QA bug?
As comment #1 correctly states, that the current generation of multi-
core ARM SoC don't allow their cpu frequencies to be changed separately.
IOW, both cores will change to the same frequency.
So our scripts should be checking the following files in sysfs:
* affected_cpus : List of CPUs that require software coordination of frequency.
* related_cpus : List of CPUs that need some sort of frequency coordination, whether software or hardware.
For all cpus in affected_cpus, we shouldn't set different governors.
