Variants

AllocateOneMsi

Allocate one gsi, and associate gsi to irqfd with register_irqfd()

Fields

irqfd: Event

device_id: DeviceId

queue_id: usize

device_name: String

AllocateOneMsiAtGsi

Allocate a specific gsi to irqfd with register_irqfd(). This must only be used when it is known that the gsi is free. Only the snapshot subsystem can make this guarantee, and use of this request by any other caller is strongly discouraged.

Fields

irqfd: Event

gsi: u32

device_id: DeviceId

queue_id: usize

device_name: String

AddMsiRoute

Add one msi route entry into the IRQ chip.

Fields

gsi: u32

msi_address: u64

msi_data: u32

ReleaseOneIrq

Fields

gsi: u32

irqfd: Event

Implementations

impl VmIrqRequest

pub fn execute<F>( &self, set_up_irq: F, sys_allocator: &mut SystemAllocator, ) -> VmIrqResponse

where F: FnOnce(IrqSetup<'_>) -> Result<()>,

Executes this request on the given Vm.

Arguments

• set_up_irq - A function that applies an IrqSetup to an IRQ chip.

This does not return a result, instead encapsulating the success or failure in a VmIrqResponse with the intended purpose of sending the response back over the socket that received this VmIrqResponse.

Trait Implementations

impl Debug for VmIrqRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VmIrqRequest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for VmIrqRequest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
