Vincent Donnefort 1517176906 cpufreq: Make policy min/max hard requirements ... When applying the policy min/max limits, the requested frequency is simply clamped to not be out of range. It means, however, if one of the boundaries isn't an available frequency, the frequency resolution can return a value out of those limits, depending on the relation used. e.g. freq{0,1,2} being available frequencies. freq0 policy->min freq1 policy->max freq2 | | | | | 17kHz 18kHz 19kHz 20kHz 21kHz __resolve_freq(21kHz, CPUFREQ_RELATION_L) -> 21kHz (out of bounds) __resolve_freq(17kHz, CPUFREQ_RELATION_H) -> 17kHz (out of bounds) If, during the policy init, we resolve the requested min/max to existing frequencies, we ensure that any CPUFREQ_RELATION_* would resolve to a frequency which is inside the policy min/max range. Making the policy limits rigid helps to introduce the inefficient frequencies support. Resolving an inefficient frequency to an efficient one should not transgress policy->max (which can be set for thermal reason) and having a value we can trust simplify this comparison.
