I also got the segfault. Setting CONFIG_RTE_EAL_UNBIND_PORTS=y is not ideal
because it would also unbind my VMNET3 management interface.
Does anyone know why the crash is happening? According to the stacktrace,
hw_addrX is 0x0 during eth_vmxnet3_dev_init.
I?m running on ubuntu 12.04LTS on ESXi
.drv_flags = RTE_PCI_DRV_NEED_IGB_UIO,
-#endif
},
.eth_dev_init = eth_vmxnet3_dev_init,
.dev_private_size = sizeof(struct vmxnet3_adapter),
Thanks.

I?m unable to get RSS to work properly with vmxnet3-pmd. The first issue is
that the number of rxqs must be power of 2. Otherwise, rte_eth_dev_start()
fails due to inability to activate vmxnet3 NIC. This is not too big of a deal,
but physical NICs don?t have this requirement.
The second issue
The vmxnet3 PCI hardware resources were never memory mapped when
RE_EAL_UNBIND_PORTS is not defined.
Specifically, pci_dev->mem_resource is not mapped. The fix is to always set
drv_flags with RTE_PCI_DRV_NEED_IGU for vmxnet3. This ensures
pci_uio_map_resource() is called.

Hi,
I?m wondering which profilers are best for profiling DPDK applications running
on VM: perf, oprofile, vtune? The first 2 are open sourced while vtune is
commercial. DPDK apps are running on ubuntu 12.04 and centos 6.5. Thanks.

Hi,
While browsing through the ixgbe pmd code, I noticed that there is
ixgbe_recv_pkts_bulk_alloc, which can be enabled if the following preconditions
are met.
* rxq->rx_free_thresh >= RTE_PMD_IXGBE_RX_MAX_BURST
* rxq->rx_free_thresh < rxq->nb_rx_desc
* (rxq->nb_rx_desc % r
Hi,
It appears that the hash computed from RSS is unidirectional. Hence, for a
5-tuple flow, packet in one direction can be routed to a queue that may be
different than packet in the other direction. I?m wondering if there is a
configuration or mechanism to get a symmetric hash so that all packe

The problem appears to be that rxmode.mq_mode was never set to ETH_MQ_RX_RSS in
testpmd.c; it?s initialized to 0. There should probably be a configuration for
that, or should be set when rxq > 1.

I?m using X520-DA2 Server Adapter E10G42BTDA PCIe Dual-Port 2xSFP+ to evaluate

Thanks, Sy Jong. I couldn?t reproduce your outcome on dpdk 1.5.1 with ixgbe. As
I sent in the earlier email, rxmode.mq_mode is defaulted to 0 (i.e.
ETH_MQ_RX_NONE); it should be set to ETH_MQ_RX_RSS.

I already have existing makefiles for my current application. I would like to
integrate dpdk into the application. ?m wondering if there is any benefit to
use dpdk?s makefiles instead of using your own makefile and linking against the
library (e.g. libintel_dpdk.a). Thanks.

Maxime,
Thanks for your comment. If we want testpmd to have RSS always enabled out of
box (note that rxq=1), then your suggestion makes sense. I?m new to dpdk so I
was trying to preserve the current behavior. Now looking back, I guess that?s
why we have an explicit disable-rss option. If I don?t
