John Baldwin ffe1b10d95 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.
