200 Say Y here to enable PCIe controller support for Sigma Designs
201 Tango SMP8759-based systems.
202
203 Note: The SMP8759 controller multiplexes PCI config and MMIO
204 accesses, and Linux doesn't provide a way to serialize them.
205 This can lead to data corruption if drivers perform concurrent
206 config and MMIO accesses.

210 tristate "Intel Volume Management Device Driver"
211 default N
212 ---help---
213 Adds support for the Intel Volume Management Device (VMD). VMD is a
214 secondary PCI host bridge that allows PCI Express root ports,
215 and devices attached to them, to be removed from the default
216 PCI domain and placed within the VMD domain. This provides
217 more bus resources than are otherwise possible with a
218 single domain. If you know your system provides one of these and
219 has devices attached to it, say Y; if you are not sure, say N.

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