ax-alloc

ArceOS global memory allocator. Provides [GlobalAllocator] implementing [core::alloc::GlobalAlloc] for use with #[global_allocator].

Features

• tlsf – TLSF byte and page allocation backed by rlsf
• buddy-slab – buddy page allocation plus per-CPU slab allocation
• global-allocator – register the selected backend as #[global_allocator]
• tracking – allocation tracking (requires ax-percpu, axbacktrace)
