Implementations§

Source§

impl VirtioBlockDevice

Source

pub unsafe fn new(pci_dev: PciDevice) -> Result<Self, &'static str>

Initialize a VirtIO block device from a PCI device

§Safety

The PCI device must be a valid VirtIO block device

Source

fn do_request( &self, request_type: RequestType, sector: u64, data_buf: Option<(&mut [u8], bool)>, ) -> Result<(), BlockError>

Submit a block request and wait for completion
