Sorry to disturb you about another problem as follows.
CPPC use the increment of Desired Performance counter and Reference Performance

Sorry to disturb you about another problem as follows.
CPPC use the increment of Desired Performance counter and Reference Performance
counter to get the CPU frequency and show it in sysfs through
'cpuinfo_cur_freq'. But ACPI CPPC doesn't specifically define the behavior of
these two
