From 89e1f7d4c66d85f42c3d52ea3866eb10cadf6153 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Tue, 31 Jul 2012 08:16:24 -0600 Subject: vfio: Add PCI device driver Add PCI device support for VFIO. PCI devices expose regions for accessing config space, I/O port space, and MMIO areas of the device. PCI config access is virtualized in the kernel, allowing us to ensure the integrity of the system, by preventing various accesses while reducing duplicate support across various userspace drivers. I/O port supports read/write access while MMIO also supports mmap of sufficiently sized regions. Support for INTx, MSI, and MSI-X interrupts are provided using eventfds to userspace.
