AML_CPC_INFO

typedef struct AmlCpcInfo AML_CPC_INFO

A structure that describes the Cpc information.

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)
