...ff6eb5ef4e2600adbec550c13b8fe72 So I started to experiment with the upstream patch: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commitdiff;h=3c076351c4027a56d5005a39a0b518a4ba393ce2;hp=69166fbf02c7a21745013f2de037bf7af26e4279 To make it apply, one needs to change 'pci_is_pcie(pdev)' into 'pdev->is_pcie'. One also needs to fiddle a little with the first chunk. I came up with the patch attached, but unfortunately the new kernel showed no improvement. Most probably I got something wrong. Anyone else here who tried this or is interested in sorting this ou...

Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. [PATCH 1/8 v4] PCI: define PCI resource names in a 'enum' [PATCH 2/8 v4] PCI: export __pci_read_base
