Update to 0.9.0. Disabled tests for now as they depend on the ctor crate which we don't have in AOSP. Bug: 237249743 Test: atest vmbase_example.integration_test Change-Id: Ibc28054a2f1ee460e49a1fbd3b637951cece3757
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.
