/*!
|
|
\param Vector - Specifies the interrupt vector to be delivered.
|
|
|
|
\param 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.
|
|
|
|
\param 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.
|
|
|
|
\param DestinationShortHand - Specifies where to send the interrupt.
|
|
APIC_DSH_Destination
|
|
APIC_DSH_Self
|
|
APIC_DSH_AllIncludingSelf
|
|
APIC_DSH_AllExclusingSelf
