Required Methods

fn sequential_read(&self, start: u64, list: &[PhysRange]) -> Result<usize>

fn sequential_write(&self, start: u64, list: &[PhysRange]) -> Result<usize>

fn len(&self) -> Result<usize>

Provided Methods

fn phys_addrs( &self, _start: DevicePage, _phys_list: &mut Vec<PagedPhysMem>, ) -> Result<usize>

Append the needed paged phys mem for this device page, return the number of appended pages.
