DESCRIPTION

    This script &lt;http://github.com/a3f/.dotfiles/blob/master/bin/lsiommu&gt;
    packaged as CPAN module. Isolation/pass-through of devices via IOMMU is
    only possible in groups. This script reads the groups out the Linux
    SysFS and displays them as a tree. If lspci(1) is available, it's used
    to display full device information.
