for example, if the\napplication uses a mixture of pinned high-priority threads and multiplexed\nlow-priority threads that share a mempool.\n\nNote that the lock-free algorithm relies on a 128-bit compare-and-swap[1],\nso it is currently limited to the x86_64 platform.\n\nThis patchset is the successor to a patchset containing only the new mempool\nhandler[2].\n\n[1] http://mails.dpdk.org/archives/dev/2019-March/125751.html\n[2] http://mails.dpdk.org/archives/dev/2019-January/123555.html\n\n---\nv4:\n- Fix test_stack.c 32-bit build by using %zu format specifier for size_t\n- Rebase onto master\n\nv3:\n- Rebase patchset onto master (test/test/ -> app/test/)\n- Fix rte_stack_std_push() segfault introduced in v2\n\nv2:\n- Reworked structure and function naming to use rte_stack_{std, lf}_...\n- Updated to the latest rte_atomic128_cmp_exchange() interface.\n- Rename STACK_F_NB -> RTE_STACK_F_LF.\n- Remove rte_rmb() and rte_wmb() from the generic push and pop implementations.\n These are obviated by rte_atomic128_cmp_exchange()'s two memorder arguments.\n- Edit stack_lib.rst text to 80 chars/line.\n- Fix rte_stack.h doxygen formatting.\n- Allocate popped_objs array from the heap\n- Fix stack_thread_push_pop bug (\"&t->sz\" -> \"t->sz\")\n- Remove unnecessary NULL check from test_stack_basic\n- Properly terminate the name string in test_stack_name_length\n- Add an empty array of struct rte_nb_lifo_elem elements\n- In rte_nb_lifo_push(), retrieve the last element from __nb_lifo_pop()\n- Split C11 implementation into a separate patchset\n\nGage Eads (8):\n stack: introduce rte stack library\n mempool/stack: convert mempool to use rte stack\n test/stack: add stack test\n test/stack: add stack perf test\n stack: add lock-free stack implementation\n stack: add C11 atomic implementation\n test/stack: add lock-free stack tests\n mempool/stack: add lock-free stack mempool handler\n\n MAINTAINERS | 9 +-\n app/test/Makefile | 3 +\n app/test/meson.build | 7 +\n app/test/test_stack.c | 423 ++++++++++++++++++++++++\n app/test/test_stack_perf.c | 356 ++++++++++++++++++++\n config/common_base | 5 +\n doc/api/doxy-api-index.md | 1 +\n doc/api/doxy-api.conf.in | 1 +\n doc/guides/prog_guide/env_abstraction_layer.rst | 10 +\n doc/guides/prog_guide/index.rst | 1 +\n doc/guides/prog_guide/stack_lib.rst | 83 +++++\n doc/guides/rel_notes/release_19_05.rst | 13 +\n drivers/mempool/stack/Makefile | 3 +-\n drivers/mempool/stack/meson.build | 6 +-\n drivers/mempool/stack/rte_mempool_stack.c | 115 +++----\n lib/Makefile | 2 +\n lib/librte_stack/Makefile | 25 ++\n lib/librte_stack/meson.build | 10 +\n lib/librte_stack/rte_stack.c | 219 ++++++++++++\n lib/librte_stack/rte_stack.h | 395 ++++++++++++++++++++++\n lib/librte_stack/rte_stack_c11_mem.h | 175 ++++++++++\n lib/librte_stack/rte_stack_generic.h | 151 +++++++++\n lib/librte_stack/rte_stack_pvt.h | 34 ++\n lib/librte_stack/rte_stack_version.map | 9 +\n lib/meson.build | 2 +-\n mk/rte.app.mk | 1 +\n 26 files changed, 1987 insertions(+), 72 deletions(-)\n create mode 100644 app/test/test_stack.c\n create mode 100644 app/test/test_stack_perf.c\n create mode 100644 doc/guides/prog_guide/stack_lib.rst\n create mode 100644 lib/librte_stack/Makefile\n create mode 100644 lib/librte_stack/meson.build\n create mode 100644 lib/librte_stack/rte_stack.c\n create mode 100644 lib/librte_stack/rte_stack.h\n create mode 100644 lib/librte_stack/rte_stack_c11_mem.h\n create mode 100644 lib/librte_stack/rte_stack_generic.h\n create mode 100644 lib/librte_stack/rte_stack_pvt.h\n create mode 100644 lib/librte_stack/rte_stack_version.map", "diff": null, "prefixes": [ "v4", "0/8" ] }
