- Set the size of each PCI slot's translation table when using the
- Calgary IOMMU. This is the size of the translation table itself
- in main memory. The smallest table, 64k, covers an IO space of
- 32MB; the largest, 8MB table, can cover an IO space of 4GB.
- Normally the kernel will make the right choice by itself.

- Enable translation even on slots that have no devices attached to
- them, in case a device will be hotplugged in the future.
- calgary=[disable=<PCI bus number>]
- Disable translation on a given PHB. For
- example, the built-in graphics adapter resides on the first bridge
- (PCI bus number 0); if translation (isolation) is enabled on this
- bridge, X servers that access the hardware directly from user
- space might stop working. Use this option if you have devices that
- are accessed from userspace directly on some PCI host bridge.
