    vfio/pci: Intel IGD host and LCP bridge config space access · f572a960
    Alex Williamson authored
    Provide read-only access to PCI config space of the PCI host bridge
    and LPC bridge through device specific regions.  This may be used to
    configure a VM with matching register contents to satisfy driver
    requirements.  Providing this through the vfio file descriptor removes
    an additional userspace requirement for access through pci-sysfs and
    removes the CAP_SYS_ADMIN requirement that doesn't appear to apply to
    the specific devices we're accessing.
