Implementations
sourceimpl Devicetree
impl Devicetree
sourcepub fn from(dtb_base_vaddr: usize) -> DeviceResult<Self>
pub fn from(dtb_base_vaddr: usize) -> DeviceResult<Self>
Load the device tree blob from the given virtual address.
sourcepub fn walk<F>(&self, device_node_op: &mut F) where
F: FnMut(&Node, &StringList<'_>, &InheritProps),
pub fn walk<F>(&self, device_node_op: &mut F) where
F: FnMut(&Node, &StringList<'_>, &InheritProps),
Traverse the tree from root by DFS, collect necessary properties, and
apply the device_node_op
to each node.
sourcepub fn bootargs(&self) -> Option<&str>
pub fn bootargs(&self) -> Option<&str>
Returns the bootargs
property in the /chosen
node, as the kernel
command line.
sourcepub fn timebase_frequency(&self) -> Option<u32>
pub fn timebase_frequency(&self) -> Option<u32>
Returns the timebase-frequency
property in the /cpus
node, as timer
sourcepub fn initrd_region(&self) -> Option<Range<usize>>
pub fn initrd_region(&self) -> Option<Range<usize>>
Returns the linux,initrd-start
and linux,initrd-end
properties in
the /chosen
node, as the init RAM disk address region.
sourcepub fn memory_regions(&self) -> DeviceResult<Vec<Range<usize>>>
pub fn memory_regions(&self) -> DeviceResult<Vec<Range<usize>>>
Returns the physical memory regions specified in the /memory
nodes.
