Detailed Description

A structure that describes the Cpc information.

Continuous Performance Control is described in DSDT/SSDT and associated to cpus/clusters in the cpu topology.

Unsupported Optional registers should be encoded with NULL resource Register {(SystemMemory, 0, 0, 0, 0)}

For values that support Integer or Buffer, integer will be used if buffer is NULL resource. If resource is not NULL then Integer must be 0

Cf. ACPI 6.4, s8.4.7.1 _CPC (Continuous Performance Control)
