[RFC PATCH 0/2] Driver for new PCI-e device

From: Keith Busch
Date: Thu Aug 27 2015 - 18:39:26 EST

The Intel Volume Management Device (VMD) is an integrated endpoint on the
platform's PCIe root complex that acts as a host bridge to a secondary
PCIe domain. BIOS can reassign one or more root ports to appear within
VMD domains instead of the primary domain. This driver enables and
enumerates the VMD domain using the root bus configuration interface
provided by the PCI subsystem.
