Another memarea: it can be from another memarea.\n\n- It supports MT-safe as long as it's specified at creation time.\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\nChengwen Feng (6):\n memarea: introduce memarea library\n test/memarea: support memarea test\n memarea: support alloc and free API\n test/memarea: support alloc and free API test\n memarea: support dump API\n test/memarea: support dump API test\n\n---\nv14:\n* address Stephen's comments: RTE_MEMAREA_LOG use easy impl and add\n __func__ print.\nv13:\n* address Morten's comments: make debug cookies optional, controlled\n by RTE_LIBRTE_MEMAREA_DEBUG; disabled by default.\n* reduce management data overhead.\nv12:\n* remove rte_memarea_refcnt_update() API which address Dongdong's\n comments.\n* refine the variable naming.\n* fix some bugs.\nv11:\n* rebase 23.03\n* remove \"app/test: add memarea to malloc-perf-autotest\" because the\n two algorithm are not comparable which also address previous\n comments.\nv10:\n* support windows platform.\n* add rte_memarea.libc perftest to malloc-perf-autotest.\nv9:\n* address Dmitry's comments.\n* drop features of SOURCE_USER and backup memarea mechanism.\n* rename rte_memarea_update_refcnt to rte_memarea_refcnt_update\n to keep with rte_mbuf_refcnt_update name style.\n* fix memarea perftest compile failed at windows platform.\n* fix spell warning.\nv8:\n* address Mattias's comments (rename ALG_DEFAULT with ALG_NEXTFIT).\n* small feature patches are combined.\n* enhanced backup memory mechanism.\n* add memarea to malloc-perf-autotest.\n* other tiny naming optimize.\nv7:\n* repost patches as there are spread over different series in patchwork.\nv6:\n* address Mattias's comments.\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 | 297 ++++++++++++++++\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_23_03.rst | 6 +\n lib/memarea/memarea_private.h | 58 ++++\n lib/memarea/meson.build | 10 +\n lib/memarea/rte_memarea.c | 448 +++++++++++++++++++++++++\n lib/memarea/rte_memarea.h | 185 ++++++++++\n lib/memarea/version.map | 15 +\n lib/meson.build | 1 +\n 14 files changed, 1087 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", "diff": null, "prefixes": [ "v14", "0/6" ] }
