Patch also does mp->flags cleanup like: * Remove redundant 'flags' API description from - __rte_mempool_generic_put - __rte_mempool_generic_get * Remove unused 'flags' param from - rte_mempool_generic_put - rte_mempool_generic_get * Fix mempool var data types int mempool.c - mz_flags is int, Change it to unsigned int. Fixes: af75078fec ("first public release") Fixes: 454a0a7009 ("mempool: use cache in single producer or consumer mode") Fixes: d6f78df6fe ("mempool: use bit flags for multi consumers and producers") Fixes: d1d914ebbc ("mempool: allocate in several memory chunks by default") Signed-off-by: Santosh Shukla --- Cc: Wenfeng Liu Cc: Lazaros Koromilas Cc: Olivier Matz v3: - Changes are based on per deprecation notice [1] [1] http://dpdk.org/dev/patchwork/patch/27079/ lib/librte_mempool/rte_mempool.c | 4 ++-- lib/librte_mempool/rte_mempool.h | 23 +++++------------------ test/test/test_mempool.c | 18 +++++++++--------- test/test/test_mempool_perf.c | 4 ++-- 4 files changed, 18 insertions(+), 31 deletions(-) diff --git a/lib/librte_mempool/rte_mempool.c b/lib/librte_mempool/rte_mempool.c index 6fc3c9c7c..237665c65 100644 --- a/lib/librte_mempool/rte_mempool.c +++ b/lib/librte_mempool/rte_mempool.c @@ -515,7 +515,7 @@ rte_mempool_populate_virt(struct rte_mempool *mp, char *addr, int rte_mempool_populate_default(struct rte_mempool *mp) { - int mz_flags = RTE_MEMZONE_1GB|RTE_MEMZONE_SIZE_HINT_ONLY; + unsigned int mz_flags = RTE_MEMZONE_1GB|RTE_MEMZONE_SIZE_HINT_ONLY; char mz_name[RTE_MEMZONE_NAMESIZE]; const struct rte_memzone *mz; size_t size, total_elt_sz, align, pg_sz, pg_shift; @@ -742,7 +742,7 @@ rte_mempool_create_empty(const char *name, unsigned n, unsigned elt_size, struct rte_tailq_entry *te = NULL; const struct rte_memzone *mz = NULL; size_t mempool_size; - int mz_flags = RTE_MEMZONE_1GB|RTE_MEMZONE_SIZE_HINT_ONLY; + unsigned int mz_flags = RTE_MEMZONE_1GB|RTE_MEMZONE_SIZE_HINT_ONLY; struct rte_mempool_objsz objsz; unsigned lcore_id; int ret; diff --git a/lib/librte_mempool/rte_mempool.h b/lib/librte_mempool/rte_mempool.h index 76b5b3b15..bd7be2319 100644 --- a/lib/librte_mempool/rte_mempool.h +++ b/lib/librte_mempool/rte_mempool.h @@ -226,7 +226,7 @@ struct rte_mempool { }; void *pool_config; /**< optional args for ops alloc. */ const struct rte_memzone *mz; /**< Memzone where pool is alloc'd. */ - int flags; /**< Flags of the mempool. */ + unsigned int flags; /**< Flags of the mempool. */ int socket_id; /**< Socket id passed at create. */ uint32_t size; /**< Max size of the mempool. */ uint32_t cache_size; @@ -1034,9 +1034,6 @@ rte_mempool_default_cache(struct rte_mempool *mp, unsigned lcore_id) * positive. * @param cache * A pointer to a mempool cache structure.
