Alex Williamson 6eb7018705 vfio-pci: Move idle devices to D3hot power state ... We can save some power by putting devices that are bound to vfio-pci but not in use by the user in the D3hot power state. Devices get woken into D0 when opened by the user. Resets return the device to D0, so we need to re-apply the low power state after a bus reset. It's tempting to try to use D3cold, but we have no reason to inhibit hotplug of idle devices and we might get into a loop of having the device disappear before we have a chance to try to use it. A new module parameter allows this feature to be disabled if there are devices that misbehave as a result of this change.
