pub struct PciRangeAllocator { /* private fields */ }
Expand description

Used to allocate MMIO regions for PCI BARs.

Implementations§

source§

impl PciRangeAllocator

source

pub const fn new(base: u64, size: u64) -> Self

Creates a new allocator from a memory range.

source

pub fn alloc(&mut self, size: u64) -> Option<u64>

Allocates a memory region with the given size.

The size should be a power of 2, and the returned value is also a multiple of size.
