Hi:

My first time to submit patch for Xen, if something incorrect, please let me know. Thanks!

 

Fixed Issues:

1.       We have to co-assign all devices behind the uppermost PCI/PCI-X bridge.

Reason: this is for the devices without FLR in HVM, but for PV domain, we need not this restricting.

 

2.       PV BCM5709 NICs in DomU cannot load successfully.

Reason: adding the Product info to xend-pci-permissive.sxp is not work because the MSI-X code. Just a minor changes for the MSI-X code to check the permissive configurations.

 

Based version: Xen-3.3.2.

 

Patch files:

Pciif.py.patch

Pciquirk.py.patch

 

Test machine:

Dell PE R610.
