179 tristate "Intel Volume Management Device Driver"
180 default N
181 ---help---
182 Adds support for the Intel Volume Management Device (VMD). VMD is a
183 secondary PCI host bridge that allows PCI Express root ports,
184 and devices attached to them, to be removed from the default
185 PCI domain and placed within the VMD domain. This provides
186 more bus resources than are otherwise possible with a
187 single domain. If you know your system provides one of these and
188 has devices attached to it, say Y; if you are not sure, say N.

190 To compile this driver as a module, choose M here: the
191 module will be called vmd.
