Bug#750959: linux-image-3.15-rc8-amd64: Add support for VGA VFIO (CONFIG_VFIO_PCI_VGA)
The requested feature is now present in the latest Debian SID kernel (3.16.7-ckt4-3): % grep VFIO /boot/config-3.16.0-4-amd64 CONFIG_VFIO_IOMMU_TYPE1=m CONFIG_VFIO=m CONFIG_VFIO_PCI=m CONFIG_VFIO_PCI_VGA=y CONFIG_KVM_VFIO=y This bug report can thus be closed. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Currently the most bleeding edge way of doing this is with the combination of kvm, qemu and vfio. However, most graphics cards don't play nice with just the plain vfio and need special considerations that need to be enabled in the kernel. I propose that we enable these special features called CONFIG_VFIO_PCI_VGA in the kernel so that people can more easily experiment with these new cool features. I asked the leading developer of VFIO VGA support (Alex Williamson) if he could think of any reason why not to enable this feature by default, and he could not think of any. The option should simply add the capability to use the x-vga feature in Qemu.
