271 tristate "Intel Volume Management Device Driver"
272 ---help---
273 Adds support for the Intel Volume Management Device (VMD). VMD is a
274 secondary PCI host bridge that allows PCI Express root ports,
275 and devices attached to them, to be removed from the default
276 PCI domain and placed within the VMD domain. This provides
277 more bus resources than are otherwise possible with a
278 single domain. If you know your system provides one of these and
279 has devices attached to it, say Y; if you are not sure, say N.

282 module will be called vmd.
