RTE memory: e.g. invoke rte_malloc_socket to obtain.\n 2. System API: e.g. invoke posix_memalign to obtain.\n 3. User provided address: it can be from extended memory as long as\n it is available. The address must be aligned to\n RTE_CACHE_LINE_SIZE.\n 4. User provided memarea: it can be from another memarea.\n\n- It provides refcnt feature which could be useful in multi-reader\n scenario.\n\n- It provides backup memory mechanism, the memarea could use another\n memarea as a backup.\n\nNote:\na) The memarea is oriented towards the application layer, which could\nprovides 'region-based memory management' [1] function.\nb) The eal library also provide memory zone/heap management, but these\nare tied to huge pages management.\n\n[1] https://en.wikipedia.org/wiki/Region-based_memory_management\n\nSigned-off-by: Chengwen Feng <fengchengwen@huawei.com>\n\nChengwen Feng (10):\n memarea: introduce memarea library\n test/memarea: support memarea test\n memarea: support alloc/free/update-refcnt API\n test/memarea: support alloc/free/update-refcnt test\n memarea: support dump API\n test/memarea: support dump test\n memarea: support backup memory mechanism\n test/memarea: support backup memory test\n memarea: detect memory corruption based on magic\n test/memarea: support no MT-safe test\n\n---\nv5:\n* fix 09/10 patch spell warning.\nv4:\n* repost patches as there are spread over different series in patchwork.\nv3:\n* add memory source of RTE memory.\n* add algorithm field to facilitate the introduction of new algorithms.\n* fix memarea log don't output problem.\nv2:\n* fix compile issues reported by dpdk-test-report.\n* address Dimitry and Jerin's comments.\n* add no MT-safe test.\n\n MAINTAINERS | 6 +\n app/test/meson.build | 2 +\n app/test/test_memarea.c | 401 +++++++++++++++++++++++\n doc/api/doxy-api-index.md | 3 +-\n doc/api/doxy-api.conf.in | 1 +\n doc/guides/prog_guide/index.rst | 1 +\n doc/guides/prog_guide/memarea_lib.rst | 55 ++++\n doc/guides/rel_notes/release_22_11.rst | 6 +\n lib/eal/common/eal_common_log.c | 1 +\n lib/eal/include/rte_log.h | 1 +\n lib/memarea/memarea_private.h | 37 +++\n lib/memarea/meson.build | 16 +\n lib/memarea/rte_memarea.c | 430 +++++++++++++++++++++++++\n lib/memarea/rte_memarea.h | 229 +++++++++++++\n lib/memarea/version.map | 16 +\n lib/meson.build | 1 +\n 16 files changed, 1205 insertions(+), 1 deletion(-)\n create mode 100644 app/test/test_memarea.c\n create mode 100644 doc/guides/prog_guide/memarea_lib.rst\n create mode 100644 lib/memarea/memarea_private.h\n create mode 100644 lib/memarea/meson.build\n create mode 100644 lib/memarea/rte_memarea.c\n create mode 100644 lib/memarea/rte_memarea.h\n create mode 100644 lib/memarea/version.map" }
