Hi All, Sorry for asking one of the most basic question of cpufreq :(
I couldn't get the difference between affected (policy->cpus) and related cpus (policy->related_cpus) in cpufreq... As per Documentation/code: affected_cpus(policy->cpus): - List of CPUs that require software coordination of frequency. - Processors part of affected_cpus share policy struct - Policy limits the frequencies that the processor can work with. related_cpus(policy->related_cpus): - List of CPUs that need some sort of frequency coordination, whether software or hardware. - Processors part of related_cpus share governer. - Governer sets the rules, about when to change limits specified by policy. Correct? So, now comes the real question: - In which scenario's should we populate affected and related cpus? - Should related cpus will always be a superset of affected cpus? -- Viresh _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
