As an option,\nRCU is used to safely free tbl8 groups that can be recycled.\nTable will not be reclaimed or reused until reader finished\nreferencing it.\n\nNew API rte_lpm_rcu_qsbr_add is introduced for application to\nregister a RCU variable that LPM library will use. This provides\nuser the handle to enable RCU that integrated in LPM library.\n\nNew API rte_ring_peek is introduced to help on management of\nreclaiming FIFO queue.\n\n\nHonnappa Nagarahalli (3):\n doc/rcu: add RCU integration design details\n test/lpm: reset total time\n test/lpm: add RCU integration performance tests\n\nRuifeng Wang (3):\n lib/ring: add peek API\n lib/lpm: integrate RCU QSBR\n app/test: add test case for LPM RCU integration\n\n app/test/test_lpm.c | 153 +++++++++++++++-\n app/test/test_lpm_perf.c | 278 ++++++++++++++++++++++++++++-\n doc/guides/prog_guide/rcu_lib.rst | 52 ++++++\n lib/librte_lpm/Makefile | 3 +-\n lib/librte_lpm/meson.build | 2 +\n lib/librte_lpm/rte_lpm.c | 223 +++++++++++++++++++++--\n lib/librte_lpm/rte_lpm.h | 22 +++\n lib/librte_lpm/rte_lpm_version.map | 6 +\n lib/librte_ring/rte_ring.h | 30 ++++\n lib/meson.build | 3 +-\n 10 files changed, 751 insertions(+), 21 deletions(-)" }
