No, but userspace governor must take care of this stuff as it want's to change freq from userspace.. > OMAP5-UEVM will remain at this frequency for a long period of time > with AVS voltage(Adaptive Voltage Scaling technique used in OMAP to > optimize operational voltage) that was meant for 1GHz! that is > definitely not stable if there is no further transition to a valid > frequency. I understand that point, but will this stay for a long time at that freq? Why aren't governors coming into picture here? > An alternative might be to ensure CPUFREQ_GOV_LIMITS takes care of that? Again, I don't see if we really really need to do this at all.. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
