Description

StorPortPoFxSetPerfState sets a component's P-state (performance or "perf" state).

Parameters

HwDeviceExtension

Pointer to the miniport's device extension.

Address

Address of the device being registered. Currently only adapters are supported, so Address must be NULL.

Component

The index that identifies the component whose P-states will be managed. This parameter is an index into the Componentsarray in the STOR_POFX_DEVICE structure that the miniport used to register the device for Storport PoFx support. If the Components array contains N elements, component indexes range from 0 to N–1.

Flags

Currently must be set to NULL.

SetIndex

The index of a previously registered perf set.

State

If the perf set contains discrete P-States, this should be an index value. If the perf set is a range, this should be a value within that range.

Context

An arbitrary context that will be passed to the perf set change callback.

Return value

StorPortPoFxSetPerfState returns STOR_STATUS_SUCCESS upon successful completion or if runtime power has been disabled, or an error code such as one of the following:
