supported by the domain (from 14 to 29 maximum).
Warning:
The following conditions must be met before using this mode:
. The total IO space required by a given PCI bus must be less than 2KB.
. Segments (sets of one or two PCI buses) are numbered in ascending order. The
number of Type 1 segments (using only one PCI bus) and Type 2 segments (using
both PCI buses) must be even. For example,
Allowed: Type 1 followed by Type 2
