Implementations

impl BuddyAllocator

pub const fn default() -> Self

pub unsafe fn free_frame_by_pa(&mut self, paddr: u64, order: usize)

pub unsafe fn free_frame_by_desc(&mut self, frame: &FrameDesc)

pub fn print_debug_info(&self)

pub fn alloc_frame(&mut self, order: usize) -> Option<FrameDesc>

fn split_buddy_block(&mut self, n: *mut Node, order: usize)

fn recursive_split_down(&mut self, order: usize) -> Option<*const Node>

pub unsafe fn init(&mut self, start: u64, end: u64)

[start: end) the physical address range to initialize the PFA. unsafe because it assumes no data race. This could only work safely during system initialization.
