ApicRequestGlobalInterrupt()

FORCEINLINE VOID ApicRequestGlobalInterrupt	(	_In_ UCHAR	DestinationProcessor,
		_In_ UCHAR	Vector,
		_In_ APIC_MT	MessageType,
		_In_ APIC_TGM	TriggerMode,
		_In_ APIC_DSH	DestinationShortHand
	)

Parameters

Vector	- Specifies the interrupt vector to be delivered.
MessageType	- Specifies the message type sent to the CPU core interrupt handler. This can be one of the following values: APIC_MT_Fixed - Delivers an interrupt to the target local APIC specified in Destination field. APIC_MT_LowestPriority - Delivers an interrupt to the local APIC executing at the lowest priority of all local APICs. APIC_MT_SMI - Delivers an SMI interrupt to target local APIC(s). APIC_MT_RemoteRead - Delivers a read request to read an APIC register in the target local APIC specified in Destination field. APIC_MT_NMI - Delivers a non-maskable interrupt to the target local APIC specified in the Destination field. Vector is ignored. APIC_MT_INIT - Delivers an INIT request to the target local APIC(s) specified in the Destination field. TriggerMode must be APIC_TGM_Edge, Vector must be 0. APIC_MT_Startup - Delivers a start-up request (SIPI) to the target local APIC(s) specified in Destination field. Vector specifies the startup address. APIC_MT_ExtInt - Delivers an external interrupt to the target local APIC specified in Destination field.
TriggerMode	- The trigger mode of the interrupt. Can be: APIC_TGM_Edge - The interrupt is edge triggered. APIC_TGM_Level - The interrupt is level triggered.
DestinationShortHand	- Specifies where to send the interrupt. APIC_DSH_Destination APIC_DSH_Self APIC_DSH_AllIncludingSelf APIC_DSH_AllExclusingSelf
