Struct Fdt

pub struct Fdt<'a> { /* private fields */ }

The reference to the FDT raw data.

Implementations

impl<'a> Fdt<'a>

pub fn from_bytes(data: &'a [u8]) -> FdtResult<'a, Self>

Create a new FDT from raw data.

pub fn from_ptr(ptr: NonNull<u8>) -> FdtResult<'a, Self>

Create a new FDT from a pointer.

pub fn version(&self) -> usize

pub fn boot_cpuid_phys(&self) -> u32

This field shall contain the physical ID of the system’s boot CPU. It shall be identical to the physical ID given in the reg property of that CPU node within the devicetree.

pub fn memory_reservation_block( &self, ) -> impl Iterator<Item = MemoryRegion> + '_

The memory reservation block provides the client program with a list of areas in physical memory which are reserved; that is, which shall not be used for general memory allocations. It is used to protect vital data structures from being overwritten by the client program.

pub fn all_nodes(&'a self) -> impl Iterator<Item = Node<'a>>

pub fn chosen(&'a self) -> Option<Chosen<'a>>

pub fn get_node_by_phandle(&'a self, phandle: Phandle) -> Option<Node<'a>>

pub fn get_node_by_name(&'a self, name: &str) -> Option<Node<'a>>

pub fn find_compatible(&'a self, with: &[&str]) -> Option<Node<'a>>

pub fn find_node(&'a self, path: &str) -> Option<Node<'a>>

if path start with ‘/’ then search by path, else search by aliases

pub fn find_aliase(&'a self, name: &str) -> Option<&'a str>

Trait Implementations

impl<'a> Clone for Fdt<'a>

fn clone(&self) -> Fdt<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
