Subject: [PATCH v5 6/9] s390x/pci: don't fence interpreted devices without MSI-X
Date: Mon, 4 Apr 2022 14:17:23 -0400 [thread overview]
Message-ID: <20220404181726.60291-7-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <20220404181726.60291-1-mjrosato@linux.ibm.com>
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.
