Subject: [PATCH] qemu: mdev: Use vfio-pci 'display' property only with
|
|
vfio-pci mdevs
|
|
|
|
S390 is aware of both vfio-pci and vfio-ccw devices, so
|
|
on S390 the capability QEMU_CAPS_VFIO_PCI_DISPLAY will be
|
|
available. Add an extra check to make sure we only set the
|
|
display to off for vfio-pci mediated devices. Otherwise we
|
|
add display for vfio-ccw device and this breaks vfio-ccw
|
|
device qemu command line.
|
|
|
|
Fixes: d54e45b6e conf: Introduce new <hostdev> attribute 'display'
