| H A D | iommu.c | diff 306472 Thu Sep 29 19:53:43 MDT 2016 jhb MFC 304858,305485: Fix various issues with PCI pass through and VT-d. 304858: Enable I/O MMU when PCI pass through is first used. Rather than enabling the I/O MMU when the vmm module is loaded, defer initialization until the first attempt to pass a PCI device through to a guest. If the I/O MMU fails to initialize or is not present, than fail the attempt to pass a PCI device through to a guest. The hw.vmm.force_iommu tunable has been removed since the I/O MMU is no longer enabled during boot. However, the I/O MMU support can be disabled by setting the hw.vmm.iommu.enable tunable to 0 to prevent use of the I/O MMU on any systems where it is buggy. 305485: Leave ppt devices in the host domain when they are not attached to a VM. This allows a pass through device to be reset to a normal device driver on the host and reused on the host. ppt devices are now always active in some I/O MMU domain when the I/O MMU is active, either the host domain or the domain of a VM they are attached to. |
