BIOS error "Major - 146 - PCI out of resource" - when multiple gigabit ethernet card is inserted(more than 3 card)

webadmin@intel.com — Thu, 11 Oct 2012 10:09:00 GMT

Test Setup Environment:

canoe pass system
BIOS version - SE5C6000.86b.01.02.006 and SE5C600.86b.99.99.x040
platform ID - S2600CP

Tried to boot the system with 4 10 gigabit ethernet card .BIOS erro is pop up with "Major -146 PCI out of resource".with 3 cards there no issue found and it is able to boot the system.

Thanks in advance.

ixgbe can have a single driver for both PF and VF

webadmin@intel.com — Mon, 13 Aug 2012 04:23:16 GMT

Hi,

I am curious to know the Implementaion of the kernel driver approach for ethernet.

In gigabit Ethernet controller PF is having the ixgbe driver and VF is having a seperate driver ixgbevf.

Queries:

1. Single kernel driver will be sufficient to maintain the PF and VF functionalities - since same driver can be loaded in the host and guest, with respective device ID the probe function will be called and it will enabled

2. or Is there any standards?

3. Any kernel Bugs for a single driver?

4. Any hypervisor changes to be done for single driver approach?

Thanks in advance

Guest OS enumeration for VF PCIe device for 82599

webadmin@intel.com — Fri, 15 Jun 2012 14:36:36 GMT

I am struk with enabling the MSIx in the Guest OS for 82599.
In hardware MSIx capability is set it has "70" PF driver is loaded to enable the Virtual function in the host then "lspci" command is used to check whether VF is enabled or not .

VF configuration space for msix "capability [70] MSIx " it is showing correct in the host.

But if i map the VF to Guest OS then it is showing "capability [40] MSIx".SO MSIx is enabled is not detect by the hardware and the VF interrupt is not functioning properly

LSPCI output for VFs in Guest
