[PATCH v3 4/8] s390x/pci: don't fence interpreted devices without MSI-X

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Lack of MSI-X support is not an issue for interpreted passthrough
devices, so let's let these in.  This will allow, for example, ISM
devices to be passed through -- but only when interpretation is
available and being used.
