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]

.

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=assign-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.

To a PV guest? Or is this just when you were booting up the machine and tried
to initialize the card?

It sounds like the HP system does have VT-d enabled or it does not support SR-
IOV in the BIOS. I would check the HP support site or give them a call.

Take a look at either of these sites below for more information on SR-IOV.

Brian,

Thanks for your information and I'd like to give them a call. 
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.

Hi yang,

Thanks for your advice.

 

But I have tired that you said just like my old description, unfortunately,
it still failed. I will double check it again.
