The main features are as follows: - The allocated object aligned at RTE_CACHE_LINE_SIZE default. - 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. User memory: it can be from e.g. rte_extmem_xxx as long as it is available. The memory's start address must be aligned to RTE_CACHE_LINE_SIZE. 4. Another memarea: it can be from another memarea. - It provides refcnt feature which could be useful in multi-reader scenario. - It provides backup memory mechanism, the memarea could use another memarea as a backup. It will attempts to allocate object from backup memarea when the current memarea failed to allocate. 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.
