Member Function Documentation

int Zygoma::ia32::MPS::IOInterruptEntry::destinationApicId (   )  const [inline]

Identifies the IO APIC to which the signal is connected. The special value of 0xff indicates the signal is connected to all IO APICs.

int Zygoma::ia32::MPS::IOInterruptEntry::destinationApicInt (   )  const [inline]

Identifies the INT INn pin of the IO APIC to which the signal is connected.

EntryType Zygoma::ia32::MPS::ConfigTableEntry::entryType (   )  const [inline, inherited]

Gets the type code of the MP config table entry.

InterruptType Zygoma::ia32::MPS::IOInterruptEntry::interruptType (   )  const [inline]

Identifies the type of interrupt.

Polarity Zygoma::ia32::MPS::IOInterruptEntry::polarity (   )  const [inline]

Documents the active polarity of the interrupt signal.

int Zygoma::ia32::MPS::IOInterruptEntry::sourceBusId (   )  const [inline]

Identifies the bus from which the interrupt signal comes.

int Zygoma::ia32::MPS::IOInterruptEntry::sourceBusIrq (   )  const [inline]

Identifies the interrupt signal from the source bus.

TriggerMode Zygoma::ia32::MPS::IOInterruptEntry::triggerMode (   )  const [inline]

Documents the trigger mode of the interrupt signal.
