Struct MMIODeviceManager 

pub struct MMIODeviceManager { /* private fields */ }

Manages the complexities of registering a MMIO device.

Implementations

impl MMIODeviceManager

pub fn new() -> MMIODeviceManager

Create a new DeviceManager handling mmio devices (virtio net, block).

pub fn register_mmio_virtio( &mut self, vm: &Vm, device_id: String, device: MMIODevice<MmioTransport>, ) -> Result<(), MmioError>

Register a virtio-over-MMIO device to be used via MMIO transport at a specific slot.

pub fn add_virtio_device_to_cmdline( cmdline: &mut Cmdline, device_info: &MMIODeviceInfo, ) -> Result<(), MmioError>

Append a registered virtio-over-MMIO device to the kernel cmdline.

pub fn register_mmio_virtio_for_boot( &mut self, vm: &Vm, device_id: String, mmio_device: MmioTransport, _cmdline: &mut Cmdline, ) -> Result<(), MmioError>

Allocate slot and register an already created virtio-over-MMIO device. Also Adds the device to the boot cmdline.

pub fn register_mmio_boot_timer( &mut self, mmio_bus: &Bus, boot_timer: Arc<Mutex<BootTimer>>, ) -> Result<(), MmioError>

Register a boot timer device.

pub fn get_virtio_device( &self, virtio_type: u32, device_id: &str, ) -> Option<&MMIODevice<MmioTransport>>

Gets the specified device.

pub fn for_each_virtio_device<F, E: Debug>(&self, f: F) -> Result<(), E>

where F: FnMut(&u32, &String, &MMIODevice<MmioTransport>) -> Result<(), E>,

Run fn for each registered virtio device.
