This affects mempools and other memzone based objects. >>From my point of view, implementing free functionality for memzones would look like malloc over memsegs. Thus, this approach moves malloc inside eal (which in turn removes a circular dependency), where malloc heaps are composed of memsegs. We keep both malloc and memzone APIs as they are, but memzones allocate its memory by calling malloc_heap_alloc. Some extra functionality is required in malloc to allow for boundary constrained memory requests. In summary, currently malloc is based on memzones, and with this approach memzones are based on malloc. v5: - Fix rte_memzone_free - Improve rte_memzone_free unit test v4: - Rebase and fix couple of merge issues v3: - Create dummy librte_malloc - Add deprecation notice - Rework some of the code - Doc update - checkpatch v2: - New rte_memzone_free - Support memzone len = 0 - Add all available memsegs to malloc heap at init - Update memzone/malloc unit tests Sergio Gonzalez Monroy (9): eal: move librte_malloc to eal/common eal: memzone allocated by malloc app/test: update malloc/memzone unit tests config: remove CONFIG_RTE_MALLOC_MEMZONE_SIZE eal: remove free_memseg and references to it eal: new rte_memzone_free app/test: update unit test with rte_memzone_free doc: announce ABI change of librte_malloc doc: update malloc documentation MAINTAINERS | 9 +- app/test/test_malloc.c | 86 ---- app/test/test_memzone.c | 454 ++++------------------ config/common_bsdapp | 8 +- config/common_linuxapp | 8 +- doc/guides/prog_guide/env_abstraction_layer.rst | 220 ++++++++++- doc/guides/prog_guide/img/malloc_heap.png | Bin 81329 -> 80952 bytes doc/guides/prog_guide/index.rst | 1 - doc/guides/prog_guide/malloc_lib.rst | 233 ----------- doc/guides/prog_guide/overview.rst | 11 +- doc/guides/rel_notes/abi.rst | 1 + drivers/net/af_packet/Makefile | 1 - drivers/net/bonding/Makefile | 1 - drivers/net/e1000/Makefile | 2 +- drivers/net/enic/Makefile | 2 +- drivers/net/fm10k/Makefile | 2 +- drivers/net/i40e/Makefile | 2 +- drivers/net/ixgbe/Makefile | 2 +- drivers/net/mlx4/Makefile | 1 - drivers/net/null/Makefile | 1 - drivers/net/pcap/Makefile | 1 - drivers/net/virtio/Makefile | 2 +- drivers/net/vmxnet3/Makefile | 2 +- drivers/net/xenvirt/Makefile | 2 +- lib/Makefile | 2 +- lib/librte_acl/Makefile | 2 +- lib/librte_eal/bsdapp/eal/Makefile | 4 +- lib/librte_eal/bsdapp/eal/rte_eal_version.map | 19 + lib/librte_eal/common/Makefile | 1 + lib/librte_eal/common/eal_common_memzone.c | 340 +++++++--------- lib/librte_eal/common/include/rte_eal_memconfig.h | 5 +- lib/librte_eal/common/include/rte_malloc.h | 342 ++++++++++++++++ lib/librte_eal/common/include/rte_malloc_heap.h | 3 +- lib/librte_eal/common/include/rte_memzone.h | 11 + lib/librte_eal/common/malloc_elem.c | 344 ++++++++++++++++ lib/librte_eal/common/malloc_elem.h | 192 +++++++++ lib/librte_eal/common/malloc_heap.c | 206 ++++++++++ lib/librte_eal/common/malloc_heap.h | 70 ++++ lib/librte_eal/common/rte_malloc.c | 259 ++++++++++++ lib/librte_eal/linuxapp/eal/Makefile | 4 +- lib/librte_eal/linuxapp/eal/eal_ivshmem.c | 17 +- lib/librte_eal/linuxapp/eal/rte_eal_version.map | 19 + lib/librte_hash/Makefile | 2 +- lib/librte_lpm/Makefile | 2 +- lib/librte_malloc/Makefile | 6 +- lib/librte_malloc/malloc_elem.c | 320 --------------- lib/librte_malloc/malloc_elem.h | 190 --------- lib/librte_malloc/malloc_heap.c | 208 ---------- lib/librte_malloc/malloc_heap.h | 70 ---- lib/librte_malloc/rte_malloc.c | 228 +---------- lib/librte_malloc/rte_malloc.h | 342 ---------------- lib/librte_malloc/rte_malloc_version.map | 16 - lib/librte_mempool/Makefile | 2 - lib/librte_port/Makefile | 1 - lib/librte_ring/Makefile | 3 +- lib/librte_table/Makefile | 1 - 56 files changed, 1929 insertions(+), 2354 deletions(-) delete mode 100644 doc/guides/prog_guide/malloc_lib.rst create mode 100644 lib/librte_eal/common/include/rte_malloc.h create mode 100644 lib/librte_eal/common/malloc_elem.c create mode 100644 lib/librte_eal/common/malloc_elem.h create mode 100644 lib/librte_eal/common/malloc_heap.c create mode 100644 lib/librte_eal/common/malloc_heap.h create mode 100644 lib/librte_eal/common/rte_malloc.c delete mode 100644 lib/librte_malloc/malloc_elem.c delete mode 100644 lib/librte_malloc/malloc_elem.h delete mode 100644 lib/librte_malloc/malloc_heap.c delete mode 100644 lib/librte_malloc/malloc_heap.h delete mode 100644 lib/librte_malloc/rte_malloc.h -- 1.9.3
