Gowrishankar,
The unit test of table got failed.
When I took a look at the code, it failed on this line in file
lib/librte_table/rte_table_hash_key8.c ,
lib/librte_table/rte_table_hash_key16.c,
lib/librte_table/rte_table_hash_key32.c:
if ((check_params_create_lru(p) != 0) ||
((sizeof(struct rte_table_hash) % RTE_CACHE_LINE_SIZE) != 0)
||
((sizeof(struct rte_bucket_4_8) % RTE_CACHE_LINE_SIZE) !=
0)) {
return NULL;
}
if ((check_params_create_lru(p) != 0) ||
((sizeof(struct rte_table_hash) % RTE_CACHE_LINE_SIZE) != 0)
||
((sizeof(struct rte_bucket_4_16) % RTE_CACHE_LINE_SIZE) !=
0)) {
return NULL;
}
if ((check_params_create_lru(p) != 0) ||
((sizeof(struct rte_table_hash) % RTE_CACHE_LINE_SIZE) != 0)
||
((sizeof(struct rte_bucket_4_32) % RTE_CACHE_LINE_SIZE) !=
0)) {
return NULL;
}
The size of rte_bucket_4_8/16/32 is not aligned to cache line size. This is
normal, because POWER has different cache line size. The change of struct
rte_bucket_4_8/16/32 may solve this problem. I didn't do further
investigation. Can you help to double check this patch?
