Merge remote-tracking branch 'awilliam/tags/vfio-pci-for-qemu-20131206.0' into staging
vfio-pci updates include: - Update linux-headers to include KVM-VFIO device support - Enable QEMU support for KVM-VFIO device - Additional Nvidia x-vga quirk to ACK MSI interrupts - Debug options to disable MSI/X KVM acceleration - Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks The KVM-VFIO device support enables KVM to manage how it handles coherency instructions in the presence of non-coherent I/O. Dave Airlie had noted that the Nvidia MSI ACK support here may just be scratching the surface, but it's better than what we have now and it's only enabled via the x-vga option, so I'm willing to add since it does enable some users. # gpg: Signature made Fri 06 Dec 2013 12:28:19 PM PST using RSA key ID 3BB08B22 # gpg: Can't check signature: public key not found # By Alex Williamson # Via Alex Williamson * awilliam/tags/vfio-pci-for-qemu-20131206.0: vfio-pci: Release all MSI-X vectors when disabled vfio-pci: Add debug config options to disable MSI/X KVM support vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirk vfio-pci: Make use of new KVM-VFIO device linux-headers: Update from v3.13-rc3 Message-id: 20131206204715.16731.12627.stgit@bling.home Signed-off-by: Anthony Liguori <aliguori@amazon.com>
