Update TEST_MAPPING Test: None Bug: 233924440 Change-Id: I7ed2c7508a8a125423f2630a52d4c988ecc33769
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::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.
