Parameters used when resolving a resource with kind [ChipsetDeviceHandleKind].

Fields

device_name: &'a str

The name of the device.

guest_memory: &'a GuestMemory

Guest memory for device DMA operations for untrusted devices.

encrypted_guest_memory: &'a GuestMemory

Guest memory for device DMA operations for trusted devices, which can access encrypted memory on CVMs.

For non-CVMs, this is the same as guest_memory.

vmtime: &'a VmTimeSource

The VM time source.

is_restoring: bool

Whether the VM is restoring from a saved state.

FUTURE: remove this once devices have a state transition for “first boot”. Device authors: try to avoid taking a dependency on this. If possible, delay any “first boot” initialization until it’s really needed.

configure: &'a mut dyn ConfigureChipsetDevice

An object to confiure the chipset device’s connection to the platform.

task_driver_source: &'a VmTaskDriverSource

The task driver source for the VM.

register_mmio: &'a mut (dyn RegisterMmioIntercept + Send)

Object to register for MMIO intercepts.

register_pio: &'a mut (dyn RegisterPortIoIntercept + Send)

Object to register for PIO intercepts.
