Hi Stephen, We were going through the patch set: https://inbox.dpdk.org/dev/20200715212228.28010-7-stephen@networkplumber.org/ and hoping to get clarification on the behaviour if post mask is not specified in the input to `dpdk-proc-info` tool. Specifically, In PATCH v3 6/7, we see this: + /* If no port mask was specified, one will be provided */ + if (enabled_port_mask == 0) { + RTE_ETH_FOREACH_DEV(i) { + enabled_port_mask |= 1u << i; However, in PATCH v4 8/8, we see this: + /* If no port mask was specified, then show non-owned ports */ + if (enabled_port_mask == 0) { + RTE_ETH_FOREACH_DEV(i) + enabled_port_mask = 1ul << i; + } Was there any specific reason to show just the last non-owned port in case the port mask was not specified? Should we show all non-owned ports in case the user doesn’t specify any port mask? Regards, Subendu.
