64k,...,8M - 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.
|
||||
|
||||
translate_empty_slots - Enable translation even on slots that have
|
||||
no devices attached to them, in case a device will be hotplugged
|
||||
in the future.
|
||||
|
||||
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.
