[−][src]Enum sunrise_kernel::devices::ioapic::DeliveryMode

pub enum DeliveryMode {
    Fixed,
    LowestPriority,
    SMI,
    NMI,
    INIT,
    ExtINT,
    Unknown(u64),
}

Specifies how the APICs listed in the destination field should act upon reception of this signal. Note that certain Delivery Modes only operate as intended when used in conjunction with a specific trigger Mode.

Variants

Fixed

Deliver the signal on the INTR signal of all processor cores listed in the destination. Trigger Mode for "fixed" Delivery Mode can be edge or level.

LowestPriority

Deliver the signal on the INTR signal of the processor core that is executing at the lowest priority among all the processors listed in the specified destination. Trigger Mode for "lowest priority". Delivery Mode can be edge or level.

SMI

System Management Interrupt. A delivery mode equal to SMI requires an edge trigger mode. The vector information is ignored but must be programmed to all zeroes for future compatibility.

NMI

Deliver the signal on the NMI signal of all processor cores listed in the destination. Vector information is ignored. NMI is treated as an edge triggered interrupt, even if it is programmed as a level triggered interrupt. For proper operation, this redirection table entry must be programmed to "edge" triggered interrupt.

INIT

Deliver the signal to all processor cores listed in the destination by asserting the INIT signal. All addressed local APICs will assume their INIT state. INIT is always treated as an edge triggered interrupt, even if programmed otherwise. For proper operation, this redirection table entry must be programmed to "edge" triggered interrupt.

ExtINT

Deliver the signal to the INTR signal of all processor cores listed in the destination as an interrupt that originated in an externally connected (8259A-compatible) interrupt controller. The INTA cycle that corresponds to this ExtINT delivery is routed to the external controller that is expected to supply the vector. A Delivery Mode of "ExtINT" requires an edge trigger mode.

Unknown(u64)

Unknown delivery mode encountered.
