Subject: [dpdk-users] Problem in dpdk mpool initialization in dpdk20.11
Date: Mon, 8 Mar 2021 07:45:53 +0000
Message-ID: <BYAPR11MB27108071AC5CABC9B8DF36C6E9939@BYAPR11MB2710.namprd11.prod.outlook.com> (raw)

Hi,

I am porting the application from dpdk 17.11 to dpdk 20.11
Application uses centos7.9 and melanox 5.2.2 PMD

Below api call works fine in dpdk17.11 but fails in dpdk20.11

rte_pktmbuf_pool_create ("mbuf_pool_0", (4096 * 64 * 16 - 1), 512, 0, RTE_MBUF_DEFAULT_BUF_SIZE) fails with error no 22 (EINVAL)
              -MBUF: error setting mempool handler
              -PANIC in app_init_mbuf_pools():
              -Cannot create mbuf pool on socket 0 (errno=22)

On adding debug trace found that  rte_mempool_ops_table.num_ops =0.

Not sure what is causing this issue. Can you please point out likely cause of this?


Best Regards,
Pinak
