Implementations

impl DevMem

pub fn alloc(size: usize) -> Result<DevMem, AllocError>

Allocates a chunk of consecutive physical, pinned memory. This should be usable by devices that do DMA.

pub fn physical_address(&self) -> u64

Returns the physical address of the memory region.

pub fn virtual_address(&self) -> usize

Returns the virtual address of the memory region.

pub fn as_mut_ptr(&self) -> *mut u8

Returns a pointer to the memory region.

pub fn as_slice(&self) -> &[u8]

pub fn len(&self) -> usize

Returns the size of the memory region.
