PEP_WORK_POWER_CONTROL structure (pep_x.h)
The PEP_WORK_POWER_CONTROL structure contains the parameters for a power control request that the platform extension plug-in (PEP) sends directly to a processor driver.
Syntax
typedef struct _PEP_WORK_POWER_CONTROL {
POHANDLE DeviceHandle;
[in] LPCGUID PowerControlCode;
PVOID RequestContext;
[in] PVOID InBuffer;
[in] SIZE_T InBufferSize;
[in] PVOID OutBuffer;
[in] SIZE_T OutBufferSize;
} PEP_WORK_POWER_CONTROL, *PPEP_WORK_POWER_CONTROL;
Members
DeviceHandle
A POHANDLE value that identifies the processor. The PEP received this handle in a previous PEP_DPM_REGISTER_DEVICE notification.
[in] PowerControlCode
A pointer to a GUID value that specifies the power control operation to perform.
RequestContext
A pointer to a PEP-defined context value. The PEP might use this value to uniquely identify a power control request message (in case the PEP issues multiple requests with the same control code to the same device).
[in] InBuffer
A pointer to a driver-allocated input buffer that contains the input parameters for this power control operation.
[in] InBufferSize
The size in bytes of the buffer pointed to by InBuffer.
[in] OutBuffer
A pointer to a driver-allocated output buffer to which the PEP writes the results of this power control operation.
[in] OutBufferSize
The size in bytes of the buffer pointed to by OutBuffer.
Remarks
The PowerControl member of the PEP_WORK_INFORMATION structure is a pointer to a PEP_WORK_POWER_CONTROL structure.
The PEP issues a power control request from a worker thread. The Windows power management framework (PoFx) forwards this request by calling the processor driver's PowerControlCallback routine, if the driver implements this routine.
