vfio: platform: Fix using devices in PM Domains

2018-06-08T16:24:37Z

If a device is part of a PM Domain (e.g. power and/or clock domain), its power state is managed using Runtime PM. Without Runtime PM, the device may not be powered up or clocked, causing subtle failures, crashes, or system lock-ups when the device is accessed by the guest. Fix this by adding Runtime PM support, powering the device when the VFIO device is opened by the guest.

vfio: platform: check reset call return code during release

2016-07-19T16:54:45Z

Release call is ignoring the return code from reset call and can potentially continue even though reset call failed. If reset_required module parameter is set, this patch is going to validate the return code and will cause stack dump with WARN_ON and warn the user of failure.
