| |
Introducing AArch64 specific version of arch_freq_get_on_cpu, cashing on existing implementation for FIE and AMUv1 support. Additionally wiring it up with cpufreq_verify_current_freq to hopefully eliminate issues when cpufreq_driver->get() returns frequency that is not entirely aligned.
The changes have been rather lightly (due to some limitations) tested on an FVP model.
v2: - Splitting the patches - Adding comment for full dyntick mode - Plugging arch_freq_get_on_cpu into cpufreq_verify_current_freq instead of in show_cpuinfo_cur_freq to allow the framework to stay more in sync with potential freq changes
