HI Shavi, I had a quick word with my office friend regarding this.
I guess you dont need to set the governor per-core. As the governor policy is per CPU not per core entity. And to set , no need to call in loop for each core. Just set it for cpu0 (main core) , and then corss-check by reading the 'scaling_governor' (same sys/devices/../... path) entry for other cores, it will be same. Also there is a scaling_available_governor to check which all governors are allowed to be set. (decided by Soc vendor) I belive this per core cpu governor might be enabled in non-smp based systems, like the new exynos having hetrogenous cores of A7 and A15 running simaltaneously, then again won't be possible to have different governor among same type of cores. Will read on this. Hope that was helpful.
