This series includes the core framework for the VFIO driver. VFIO is a userspace driver interface meant to replace both the KVM device assignment code as well as interfaces like UIO. Please see patch 1/5 for a complete description of VFIO, what it can do, and how it's designed. This series can also be found here: git://github.com/awilliam/linux-vfio.git vfio-next This plus the PCI VFIO bus driver for exposing PCI devices to userspace can be found here: git://github.com/awilliam/linux-vfio.git vfio-next-staging or here for a linux-2.6.git based tree: git://github.com/awilliam/linux-vfio.git vfio-linux-staging A fully functional qemu driver for doing non-KVM based PCI device assignment can be found here: git://github.com/awilliam/qemu-vfio.git vfio-ng I'd like to propose VFIO for inclusion in Linux 3.4, starting with this core framework series. Once we have agreement on these, I'll split up and post the VFIO PCI bus driver for inclusion as well. I can also host the above vfio-next branch for inclusion in linux-next. Please review and comment. Thanks, Alex v2: Interrupt setup ioctl rework based on comments by Konrad. The interrupt ioctls are no longer exclusively targeted at eventfds, allowing for more flexibility of other vfio bus drivers making use of alternate mechanisms. Also updated vfio_iommu_info to report common IOMMU geometry fields that we know we're going to need for Freescale PAMU. Additional ioctls and fields to be added via flags as they're implemented in the IOMMU API. --- Alex Williamson (5): vfio: VFIO core Kconfig and Makefile vfio: VFIO core IOMMU mapping support vfio: VFIO core group interface vfio: VFIO core header vfio: Introduce documentation for VFIO driver Documentation/ioctl/ioctl-number.txt | 1 Documentation/vfio.txt | 359 ++++++++++ MAINTAINERS | 8 drivers/Kconfig | 2 drivers/Makefile | 1 drivers/vfio/Kconfig | 8 drivers/vfio/Makefile | 3 drivers/vfio/vfio_iommu.c | 611 +++++++++++++++++ drivers/vfio/vfio_main.c | 1248 ++++++++++++++++++++++++++++++++++ drivers/vfio/vfio_private.h | 36 + include/linux/vfio.h | 395 +++++++++++ 11 files changed, 2672 insertions(+), 0 deletions(-) create mode 100644 Documentation/vfio.txt create mode 100644 drivers/vfio/Kconfig create mode 100644 drivers/vfio/Makefile create mode 100644 drivers/vfio/vfio_iommu.c create mode 100644 drivers/vfio/vfio_main.c create mode 100644 drivers/vfio/vfio_private.h create mode 100644 include/linux/vfio.h -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
