    My default assumption would be that this resolves an issue with
    assigning this device to a userspace or VM driver through vfio-pci, as
    most in-kernel drivers don't make use of this interface themselves;
    they often know more device specific ways to re-initialize hardware.
    This reset path is also trivially accessible through pci-sysfs. I
    don't expect nouveau would have much use for this even if it did
    include support for these devices. Thanks,

    Alex
