Snap for 9410508 from 9d2a1b8de60bb0852d12adba4fa8f4357d3660b7 to udc-release Change-Id: I6d17549231e5117e3cbe0d5a5f8d4e189cc8e492
An (almost) drop-in replacement for phil-opp/linked-list-allocator. But it uses buddy system instead.
To use buddy_system_allocator for global allocator:
use buddy_system_allocator::LockedHeap; #[global_allocator] static HEAP_ALLOCATOR: LockedHeap = LockedHeap::<32>::empty();
To init the allocator:
unsafe { HEAP_ALLOCATOR.lock().init(heap_start, heap_size); // or HEAP_ALLOCATOR.lock().add_to_heap(heap_start, heap_end); }
You can also use FrameAllocator and LockedHeapWithRescue, see their documentation for usage.
use_spin (default): Provide a LockedHeap type that implements the GlobalAlloc trait by using a spinlock.const_fn (nightly only): Provide const fn version of LockedHeapWithRescue::new.Some code comes from phil-opp's linked-list-allocator.
