Message-ID: <HK0PR01MB2482602111034C33C9E7BE2AE93B0@HK0PR01MB2482.apcprd01.prod.exchangelabs.com> (raw)

Hello ,

I have a trouble in using rxq param, when I set rxq=2, but only queue 0 is useful, queue 1 is zero of usage pmd.

the configuration is below :

    Bridge br-int
        datapath_type: netdev
        Port br-int
            Interface br-int
                type: internal
        Port dpdk1
            Interface dpdk1
                type: dpdk
                options: {dpdk-devargs="0000:21:00.1", n_rxq="2", ofport_request="2"}


This is my test result:

pmd thread numa_id 2 core_id 19:
  isolated : false
pmd thread numa_id 2 core_id 20:
  isolated : true
  port: dpdk1             queue-id:  0 (enabled)   pmd usage: 96 %
pmd thread numa_id 2 core_id 21:
  isolated : true
  port: dpdk1             queue-id:  1 (enabled)   pmd usage:  0 %


Someone can tell me how to configure ovs-dpdk to use the both queue0 and queue 1?
Thanks!

Best regards.
