Integrate RCU QSBR to make it easier for the applications to use lock free algorithm.
Resource reclamation implementation was split from the original series, and has already been part of RCU library. Rework the series to base hash integration on RCU reclamation APIs. Refer 'Resource reclamation framework for DPDK' available at [1] to understand various aspects of integrating RCU library into other libraries. [1] https://doc.dpdk.org/guides/prog_guide/rcu_lib.html Introduce a new API rte_hash_rcu_qsbr_add for application to register a RCU variable that hash library will use. Functional tests and performance tests are added to cover the integration with RCU. --- v3: - Add documentation - Add unit tests v2: - Remove defer queue related functions and use resource reclamation APIs from the RCU QSBR library instead - Remove patch (net/ixgbe: avoid multpile definitions of 'bool') from the series as it is already accepted Dharmik Thakkar (3): lib/hash: integrate RCU QSBR test/hash: replace rte atomic with C11 atomic APIs test/hash: add tests for integrated RCU QSBR app/test/test_hash.c | 390 ++++++++++++++++++++++++- app/test/test_hash_readwrite_lf_perf.c | 260 +++++++++++++---- doc/guides/prog_guide/hash_lib.rst | 11 +- lib/librte_hash/meson.build | 1 + lib/librte_hash/rte_cuckoo_hash.c | 300 ++++++++++++++----- lib/librte_hash/rte_cuckoo_hash.h | 8 + lib/librte_hash/rte_hash.h | 77 ++++- lib/librte_hash/rte_hash_version.map | 2 +- 8 files changed, 917 insertions(+), 132 deletions(-) -- 2.17.1
