PROCESSOR_HALT_ROUTINE callback function

Description

A Halt callback routine transitions the processor to an idle state.

Parameters

Context [in, out, optional]

A pointer to a PEP-defined processor-halt context. This pointer is the Context parameter value that the PEP previously passed to the ProcessorHalt routine.

Return value

A Halt callback routine may or may not return. If this routine does return, it returns STATUS_SUCCESS to indicates that the processor successfully entered the idle state. Otherwise, it returns an appropriate error status code.

Remarks

This routine is implemented by the platform extension plug-in (PEP) and is called by the Windows power management framework (PoFx). The ProcessorHalt routine accepts a pointer to a Halt callback routine as a parameter.

The PEP's Halt routine is called at the same IRQL at which the PEP called ProcessorHalt.
