[LSC] Add LOCAL_LICENSE_KINDS to external/rust/crates/buddy_system_allocator Added SPDX-license-identifier-MIT to: Android.bp Bug: 68860345 Bug: 151177513 Bug: 151953481 Test: m all Change-Id: I8e056718b8d5179ce0623adaf08c70bba0bf4633
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.
