This information is stripped from the description for parameter cache_size of function rte_mempool_create. Now rte_mempool_create function will check cache_size value less than mempool size /1.5. In test_sched.c, mempool size and cache size are all 32 and not match mempool cache size checking rule. This will cause sched_autotest not work. > > #define NB_MBUF 32 > > #define MBUF_DATA_SZ (2048 + RTE_PKTMBUF_HEADROOM) > > -#define PKT_BURST_SZ 32 > > +#define PKT_BURST_SZ 0 > > #define MEMPOOL_CACHE_SZ PKT_BURST_SZ > > Shouldn't be MEMPOOL_CACHE_SZ to set to 0? Macro PKT_BURST_SZ not used in this file, MEMPOOL_CACHE_SZ should be set to 0.
