Migrate 25 crates to monorepo am: fc60ad5bc7 am: d4c4cf4dc6 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/buddy_system_allocator/+/3217133 Change-Id: Ic259f619ea0e5387bb367a472d3981e9f0f9b5c8 Signed-off-by: Automerger Merge Worker <[email protected]>
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.
