Subject: [Xen-devel] about sr-iov

Hi,

I got a = problem when prepared to pass-thru 82576 ethernet card with SR-IOV support. =

The = 82576 card is build-in on the board. When loading igb driver for the card, dmesg show = some errors like:

pci = 0000:05:00.0: BAR 10: can't allocate mem resource = [0xfbf00000-0xfbefffff]

=A1=AD

igb = 0000:05:00.0: not enough MMIO resources for SR-IOV

igb = 0000:05:00.0: Failed to initialize SR-IOV virtualization

Some = system information from DMI as below:

XEN = 4.0.0, DOM0 kernel 2.6.32, igb driver 2.2.9

System = Information

        Manufacturer: HP

        Product Name: ProLiant DL160 G6

BIOS = Information

        Vendor: HP

        Version: O33

        Release Date: 06/10/2009

        Address: 0xF0000

        Runtime Size: 64 kB

        ROM Size: 2048 kB

        BIOS Revision: 8.15

LAN = option rom, the version is intel agent boot GE 1.3.24, PXE2.1

Processor Information

        Socket Designation: Proc 2

        Type: Central Processor

        Family: Xeon

        Manufacturer: Intel            =

        Signature: Type 0, Family 6, Model 26, Stepping 5

Version: Intel(R) Xeon(R) CPU           = E5504 @ 2.00GHz

The same = igb driver works well on a dell server with 82576 adapter. I thought BIOS got some = problem to assign right memory for VFs and I tried to pass = *pci=3Dassign-busses* to kernel, but it still failed. Does the 82576 card SR-IOV need a BIOS = enable and a *REBOOT* to make the function active? Can anyone just = give me some ideas? Thanks.

But I also concern that why it still failed when I tried to make os kernel do allocation for the pci buses. It seems very interesting if it could be a work around for the BIOS with no sr-iov enabled.
