Windows Driver Kit DDI reference (nc-pep_x-pepcallbackpoweroncrashdumpdevice)

PEPCALLBACKPOWERONCRASHDUMPDEVICE callback function (pep_x.h)

Description

The PowerOnDumpDeviceCallback callback routine turns on the crash-dump device.

Parameters

CrashdumpInformation [in]

A pointer to a PEP_CRASHDUMP_INFORMATION structure that contains information about the crash-dump device.

Return value

This routine returns TRUE if it succeeds in turning on power to the crash-dump device. Otherwise, it returns FALSE.

Remarks

This routine is implemented by the platform extension plug-in (PEP). The routine handles requests from the Windows kernel to turn on the crash-dump device so that a crash dump can be saved to disk.

The PEP registers its PowerOnDumpDeviceCallback routine in response to a PEP_DPM_REGISTER_CRASHDUMP_DEVICE notification from the Windows power management framework (PoFx).

The PowerOnDumpDeviceCallback routine is called at IRQL = HIGH_LEVEL with interrupts disabled. Thus, this routine cannot use timers, events, or any synchronization primitives other than spin locks.
