[dpdk-dev] dpdk-1.6.0r1 problem with Intel 82599ES

[Jun Xiao]

Hi,

I am running dpdk-1.6.0r1 with Intel 82599ES with some problems:
- The test driver is l2fwd, and it is started successfully without any
problem (all DEBUG build flags are enabled, but I didn't find anything
abnormal)
- l2fwd cannot see any packet generated by pktgen on another machine.
- The connectivity between l2fwd machine and pktgen machine is fine
(verified by ping before igb_uio is loaded)
- # tools/pci_unbind.py --status

Network devices using IGB_UIO driver
====================================
0000:22:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection'
drv=igb_uio unused=
0000:22:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection'
drv=igb_uio unused=

Network devices using kernel driver
===================================
0000:01:00.0 'NetXtreme II BCM5709 Gigabit Ethernet' if=em1 drv=bnx2
unused=<none> *Active*
0000:01:00.1 'NetXtreme II BCM5709 Gigabit Ethernet' if=em2 drv=bnx2
unused=<none>

I am pretty confident on the procedures since I tried it out on
another setup with Intel I350 Gigabit NIC.

Thanks,
Jun

Sorry for the spam, I just noticed it's AMD cpu! Is it possible to
make it fail quickly if dpdk cannot really work with AMD cpu?

It's not really CPU relevance but IOMMU fault, iommu=pt kernel option
solves the problem.
