From 24b4bb8123904e066ec0f47f4e8661e75ef8cace Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Mon, 13 Jul 2015 17:38:45 +0100 Subject: [PATCH] hash: rename unused field The cuckoo hash has a fixed number of entries per bucket, so the configuration parameter for this is unused. We change this field in the parameters struct to "reserved" to indicate that there is now no such parameter value, while at the same time keeping ABI consistency. Fixes: 48a399119619 ("hash: replace with cuckoo hash implementation") Suggested-by: Thomas Monjalon Signed-off-by: Bruce Richardson --- app/test/test_func_reentrancy.c | 1 - app/test/test_hash_perf.c | 1 - app/test/test_hash_scaling.c | 1 - drivers/net/enic/enic_clsf.c | 2 -- examples/l3fwd-power/main.c | 2 -- examples/l3fwd-vf/main.c | 1 - examples/l3fwd/main.c | 2 -- lib/librte_hash/rte_hash.h | 2 +- 8 files changed, 1 insertion(+), 11 deletions(-) diff --git a/app/test/test_func_reentrancy.c b/app/test/test_func_reentrancy.c index 85504c09bf..be617739e3 100644 --- a/app/test/test_func_reentrancy.c +++ b/app/test/test_func_reentrancy.c @@ -226,7 +226,6 @@ hash_create_free(__attribute__((unused)) void *arg) struct rte_hash_parameters hash_params = { .name = NULL, .entries = 16, - .bucket_entries = 4, .key_len = 4, .hash_func = (rte_hash_function)rte_jhash_32b, .hash_func_init_val = 0, diff --git a/app/test/test_hash_perf.c b/app/test/test_hash_perf.c index e9a522b5ac..a87fc80d0e 100644 --- a/app/test/test_hash_perf.c +++ b/app/test/test_hash_perf.c @@ -100,7 +100,6 @@ int32_t positions[KEYS_TO_ADD]; /* Parameters used for hash table in unit test functions. */ static struct rte_hash_parameters ut_params = { .entries = MAX_ENTRIES, - .bucket_entries = BUCKET_SIZE, .hash_func = rte_jhash, .hash_func_init_val = 0, }; diff --git a/app/test/test_hash_scaling.c b/app/test/test_hash_scaling.c index 682ae94cc2..39602cbc82 100644 --- a/app/test/test_hash_scaling.c +++ b/app/test/test_hash_scaling.c @@ -129,7 +129,6 @@ test_hash_scaling(int locking_mode) uint64_t i, key; struct rte_hash_parameters hash_params = { .entries = num_iterations*2, - .bucket_entries = 16, .key_len = sizeof(key), .hash_func = rte_hash_crc, .hash_func_init_val = 0, diff --git a/drivers/net/enic/enic_clsf.c b/drivers/net/enic/enic_clsf.c index ca12d2d09a..9c2abfb441 100644 --- a/drivers/net/enic/enic_clsf.c +++ b/drivers/net/enic/enic_clsf.c @@ -63,7 +63,6 @@ #define SOCKET_0 0 #define ENICPMD_CLSF_HASH_ENTRIES ENICPMD_FDIR_MAX -#define ENICPMD_CLSF_BUCKET_ENTRIES 4 void enic_fdir_stats_get(struct enic *enic, struct rte_eth_fdir_stats *stats) { @@ -245,7 +244,6 @@ int enic_clsf_init(struct enic *enic) struct rte_hash_parameters hash_params = { .name = "enicpmd_clsf_hash", .entries = ENICPMD_CLSF_HASH_ENTRIES, - .bucket_entries = ENICPMD_CLSF_BUCKET_ENTRIES, .key_len = RTE_HASH_KEY_LENGTH_MAX, .hash_func = DEFAULT_HASH_FUNC, .hash_func_init_val = 0, diff --git a/examples/l3fwd-power/main.c b/examples/l3fwd-power/main.c index d4eba1a3c9..6eb459dc53 100644 --- a/examples/l3fwd-power/main.c +++ b/examples/l3fwd-power/main.c @@ -1247,7 +1247,6 @@ setup_hash(int socketid) struct rte_hash_parameters ipv4_l3fwd_hash_params = { .name = NULL, .entries = L3FWD_HASH_ENTRIES, - .bucket_entries = 4, .key_len = sizeof(struct ipv4_5tuple), .hash_func = DEFAULT_HASH_FUNC, .hash_func_init_val = 0, @@ -1256,7 +1255,6 @@ setup_hash(int socketid) struct rte_hash_parameters ipv6_l3fwd_hash_params = { .name = NULL, .entries = L3FWD_HASH_ENTRIES, - .bucket_entries = 4, .key_len = sizeof(struct ipv6_5tuple), .hash_func = DEFAULT_HASH_FUNC, .hash_func_init_val = 0, diff --git a/examples/l3fwd-vf/main.c b/examples/l3fwd-vf/main.c index ccbb02fdce..01f610ed61 100644 --- a/examples/l3fwd-vf/main.c +++ b/examples/l3fwd-vf/main.c @@ -251,7 +251,6 @@ static lookup_struct_t *l3fwd_lookup_struct[NB_SOCKETS]; struct rte_hash_parameters l3fwd_hash_params = { .name = "l3fwd_hash_0", .entries = L3FWD_HASH_ENTRIES, - .bucket_entries = 4, .key_len = sizeof(struct ipv4_5tuple), .hash_func = DEFAULT_HASH_FUNC, .hash_func_init_val = 0, diff --git a/examples/l3fwd/main.c b/examples/l3fwd/main.c index 5c22ed1846..def95940fb 100644 --- a/examples/l3fwd/main.c +++ b/examples/l3fwd/main.c @@ -2162,7 +2162,6 @@ setup_hash(int socketid) struct rte_hash_parameters ipv4_l3fwd_hash_params = { .name = NULL, .entries = L3FWD_HASH_ENTRIES, - .bucket_entries = 4, .key_len = sizeof(union ipv4_5tuple_host), .hash_func = ipv4_hash_crc, .hash_func_init_val = 0, @@ -2171,7 +2170,6 @@ setup_hash(int socketid) struct rte_hash_parameters ipv6_l3fwd_hash_params = { .name = NULL, .entries = L3FWD_HASH_ENTRIES, - .bucket_entries = 4, .key_len = sizeof(union ipv6_5tuple_host), .hash_func = ipv6_hash_crc, .hash_func_init_val = 0, diff --git a/lib/librte_hash/rte_hash.h b/lib/librte_hash/rte_hash.h index 68109d5182..1cddc077a2 100644 --- a/lib/librte_hash/rte_hash.h +++ b/lib/librte_hash/rte_hash.h @@ -75,7 +75,7 @@ typedef uint32_t (*rte_hash_function)(const void *key, uint32_t key_len, struct rte_hash_parameters { const char *name; /**< Name of the hash. */ uint32_t entries; /**< Total hash table entries. */ - uint32_t bucket_entries; /**< Bucket entries. */ + uint32_t reserved; /**< Unused field.
