The UpdateProcessorIdleState routine is called by the platform extension plug-in (PEP) to update the properties of the specified processor idle state.
ProcessorHandle [in]A POHANDLE value that represents the registration of the processor (as a device) with the Windows power management framework (PoFx). The PEP previously received this handle from PoFx during the PEP_DPM_REGISTER_DEVICE notification that informed the PEP that the processor had been registered with PoFx.
ProcessorState [in]An index that identifies the processor idle state whose properties are to be updated. In response to a previous PEP_NOTIFY_PPM_QUERY_IDLE_STATES_V2 notification, the PEP specified the number of supported processor idle states and the properties of these states. If the PEP specified N processor idle states, valid processor idle state indexes range from 0 to N-1.
Update [in]A pointer to a PEP_PROCESSOR_IDLE_STATE_UPDATE structure that contains the updated properties of the processor idle state.
UpdateProcessorIdleState returns STATUS_SUCCESS if it successfully updates the properties of the processor idle state. Possible error return values include the following status codes.
| Return value | Description |
|---|---|
| STATUS_NOT_SUPPORTED | The version number in the PEP_PROCESSOR_IDLE_STATE_UPDATE structure is not a supported value. |
| STATUS_NOT_IMPLEMENTED | The UpdateProcessorIdleState routine is not implemented for this processor. |
This routine is implemented by PoFx and is called by the PEP. The UpdateProcessorIdleState member of the PEP_KERNEL_INFORMATION_STRUCT_V3 structure is a pointer to an UpdateProcessorIdleState routine.
The UpdateProcessorIdleState routine must be called at IRQL = PASSIVE_LEVEL.
