You may also want to mention the various boot time parameters (or at
least some of them).  The following comment is snipped from
xen/drivers/passthrough/iommu.c.

        eSk

/*
 * The 'iommu' parameter enables the IOMMU.  Optional comma separated
 * value may contain:
 *
 *   off|no|false|disable       Disable IOMMU (default)
 *   pv                         Enable IOMMU for PV domains
 *   no-pv                      Disable IOMMU for PV domains (default)
 *   force|required             Don't boot unless IOMMU is enabled
 *   passthrough                Enable VT-d DMA passthrough (no DMA
 *                              translation for Dom0)
 *   no-snoop                   Disable VT-d Snoop Control
 *   no-qinval                  Disable VT-d Queued Invalidation
 *   no-intremap                Disable VT-d Interrupt Remapping
