If I right understand, the latest build of
xen support using of amd iommu technology, my test platform Nvidia mcp55 pro
chipset based had this technology, but then I running my xen-linux with
amd_enable_iommu key in grub menu.lst, I’m getting message AMD IOMMU: Not
found! In xen dmesg output. Are there any ways for make iommu on my platform to
work?
