Enum zircon_object::dev::PcieIrqMode

#[repr(u32)]pub enum PcieIrqMode {
    Disabled,
    Legacy,
    Msi,
    MsiX,
    Count,
}

Enumeration which defines the IRQ modes a PCIe device may be operating in.

Variants

Disabled

All IRQs are disabled. 0 total IRQs are supported in this mode.

Legacy

Devices may support up to 1 legacy IRQ in total. Exclusive IRQ access cannot be guaranteed (the IRQ may be shared with other devices)

Msi

Devices may support up to 32 MSI IRQs in total. IRQs may be allocated exclusively, resources permitting.

MsiX

Devices may support up to 2048 MSI-X IRQs in total. IRQs may be allocated exclusively, resources permitting.

Count
