Subject: DPDK on Xen Server
Date: Tue, 25 Feb 2014 09:44:23 +0800	[thread overview]
Message-ID: <201402250944205674299@gmail.com> (raw)

hi
    I'm trying running the latest version of INTEL DPDK on my virtualized guest upon a xen server.
    The guest is gentoo, and kernel version 2.6.39, compiled without xen support, since I don't want to use the virtio function.
    The host is 2.6.32.43-0.4.1.xs1.6.10.734.170748xen.

I'v done the following steps:
1. Compile the DPDK for the gentoo kernel
2. insmod uio.ko and igb_uio.ko
3. unbind the NIC from the original NIC driver, and HERE THE TROUBLES COME...

Here is the lspci result on my gentoo:
#lspci | grep Ethernet
00:04.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 03)
00:05.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 03)
00:06.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 03)

But when I unbind the pci device 0000:00:05.0 using the following command:
echo 0000:00:05.0 > /sys/bus/pci/drivers/e1000/unbind 
it just hanged, with a process state D+.

What's this problem?
How could I solve it?

Best Regards!
