I saw a topic 'Multi-core decision co-ordination' at https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/CPUFreq . Is it still going on?
Richard,
This was related to teaching cpufreq to synchronise the scaling of frequency on both cores in case of a hardware constraint. But that is already taken care of by the cpufreq core (affected_cpus, related_cpus)
policy->shared_type = CPUFREQ_SHARED_TYPE_ANY; cpumask_setall(policy->cpus); Do you mean add above to cpufreq_driver.init ? When suspend/resume, cpufreq_driver.init/exit also be called multi times, though finally only cpu0 inited.
Thanks Richard
Regards, Amit
