The main features are as follows: - The memory region can be initialized from the following memory sources: 1. HEAP: e.g. invoke rte_malloc_socket. 2. LIBC: e.g. invoke posix_memalign. 3. Another memarea: it can be from another memarea. - It supports MT-safe as long as it's specified at creation time. - The address returned by the allocator is align to 8B. Note: a) The memarea is oriented towards the application layer, which could provides 'region-based memory management' [1] function. b) The eal library also provide memory zone/heap management, but these are tied to huge pages management.
