Patch 1~2: It is required to ensure that amu can continue to work normally during the sample period while cstate is enabled.
Patch 3: Even works in the mmio mode, cpc_read still has random delay errors, so let's extend the sampling time.
Zeng Heng (3): arm64: cpufeature: Export cpu_has_amu_feat() cpufreq: CPPC: Keep the target core awake when reading its cpufreq rate cpufreq: CPPC: Eliminate the impact of cpc_read() latency error
