VFIO is a kernel 3.6+ driver allowing secure DMA from userspace by means of using IOMMU instead of working directly with physical memory like igb_uio does. Short summary: * Adding support for VFIO in EAL PCI code * Adding new command-line parameter for VFIO interrupt type * Adding support for VFIO in setup.sh * Renaming igb_uio_bind to dpdk_nic_bind and adding support for VFIO there * Removing PCI ID list from igb_uio, effectively making it another generic PCI driver similar to pci_stub, vfio-pci et al * Adding autotest for VFIO interrupt types * Making igb_uio and VFIO compilation optional v2 fixes: * Fixed a couple of resource leaks v3 fixes: * Fixed various checkpatch.pl issues * Added MSI interrupt support * Added an option to automatically determine interrupt type * Fixed various issues of commit atomicity v4 fixes: * Rebased on top of 5ebbb17281645b23359fbd49133bb639b63ba88c * Fixed a typo in EAL command-line help text v5 fixes: * Fixed missing virtio change to RTE_PCI_DRV_NEED_MAPPING * Fixed compile issue when VFIO was disabled (introduced in v3) Tested-by: Waterman Cao This patch has been tested by intel. We tested this patch with the following functions: * Layer-2 Forwarding support * Sample commands test * Packet forwarding checking * Bind and unbind VFIO driver * Compile igb_uio driver ( Linux kernel < 3.6) * Interrupt model test under Legacy|msi|msix All cases passed.
