Required Methods§

Source

fn mmio_device(&self, addr: MmioAddress) -> Option<(&MmioRange, &Self::D)>

Return a reference to the device registered at addr, together with the associated range, if available.

Source

fn mmio_read(&self, addr: MmioAddress, data: &mut [u8]) -> Result<(), Error>

Dispatch a read operation to the device registered at addr.

Source

fn mmio_write(&self, addr: MmioAddress, data: &[u8]) -> Result<(), Error>

Dispatch a write operation to the device registered at addr.

Source

fn register_mmio( &mut self, range: MmioRange, device: Self::D, ) -> Result<(), Error>
