Hi Rafael,
I am very confused on this, can you help me understand ?
- CPUFREQ_ETERNAL = -1
- unsigned int transition_latency = CPUFREQ_ETERNAL, will set it to UINT_MAX.
- Many drivers do it today
cpufreq.c
if (policy->governor->max_transition_latency &&
policy->cpuinfo.transition_latency >
policy->governor->max_transition_latency) {
- And this check will always fail, unless max_transition_latency is zero.
What am I missing ?
