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
