[Xen-users] igb pciback and e1000e pciback not work.

[èé <xnhp0320@xxxxxxxxx>]

I'm using Xen 4.01 and jeremy's pvops kernel, the kernel version is 2.6.32.18.
At first I want to test the performance of pci passthrough Âwhen it comes to the network card 82571EB

I'm using the Jeremy's kernel 2.6.32.18 as DomU kernel too.

And I found if the interface is not connected, I mean the network card receives no packet, ( the network card doesn't connect to the switch ),
it's fine. when I connect it to a switch , I got a lot of "Detected Tx Unit Hang" in dmesg of the DomU kernel

and a kernel oops saying:

Pid: 0, comm: swapper Not tained 2.6.32.18-xen #4
warn_slowpath_fmt+0x41/0x50

the ooops image is in the attachment of this post.

I've checked the mailing list, some one said it's about the e1000e driver with a wrong

config of the EEPROM.

So I switch to use the network card 82575EB with igb driver
It seems to work well,Â

until I find it can't receive any packets in DomU.

And I see a lot of packets dropped when I ifconfig these interfaces.

Anyone knows how to deal with this ?
