PEP_QUERY_COMPONENT_PERF_CAPABILITIES structure (pep_x.h)
The PEP_QUERY_COMPONENT_PERF_CAPABILITIES structure specifies the number of performance state (P-state) sets that are defined for a component.
Syntax
typedef struct _PEP_QUERY_COMPONENT_PERF_CAPABILITIES {
[in] PEPHANDLE DeviceHandle;
[in] ULONG Component;
[out] ULONG SetCount;
} PEP_QUERY_COMPONENT_PERF_CAPABILITIES, *PPEP_QUERY_COMPONENT_PERF_CAPABILITIES;
Members
[in] DeviceHandle
A PEPHANDLE value that identifies the device. The PEP supplied this handle in response to a previous PEP_DPM_REGISTER_DEVICE notification.
[in] Component
The index that identifies the component. This member is an index into the Components array in the PEP_DEVICE_REGISTER_V2 structure that the PEP previously supplied in response to the PEP_DPM_REGISTER_DEVICE notification for this device. If the Components array contains N elements, component indexes range from 0 to N–1.
[out] SetCount
The number of P-state sets that are defined for this component.
Remarks
This structure is used by the PEP_DPM_QUERY_COMPONENT_PERF_CAPABILITIES notification. The DeviceHandle and Component members contain input values that are supplied by the Windows power management framework (PoFx) when this notification is sent. The SetCount member contains an output value that the PEP writes to the structure in response to the notification.
