  "message": "vfio-pci: Reset workaround for AMD Bonaire and Hawaii GPUs\n\nSomehow these GPUs manage not to respond to a PCI bus reset, removing\nour primary mechanism for resetting graphics cards.  The result is\nthat these devices typically work well for a single VM boot.  If the\nVM is rebooted or restarted, the guest driver is not able to init the\ncard from the dirty state, resulting in a blue screen for Windows\nguests.\n\nThe workaround is to use a device specific reset.  This is not 100%\nreliable though since it depends on the incoming state of the device,\nbut it substantially improves the usability of these devices in a VM.\n\nCredit to Alex Deucher \u003calexander.deucher@amd.com\u003e for his guidance.\n\nSigned-off-by: Alex Williamson \u003calex.williamson@redhat.com\u003e\n",
