261 Note: The SMP8759 controller multiplexes PCI config and MMIO
262 accesses, and Linux doesn't provide a way to serialize them.
263 This can lead to data corruption if drivers perform concurrent
264 config and MMIO accesses.

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