Subject: [PATCH 2/8] s390x/pci: Keep track of the PCI Function type
Date: Tue, 19 Jan 2021 15:44:13 -0500	[thread overview]
Message-ID: <1611089059-6468-3-git-send-email-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <1611089059-6468-1-git-send-email-mjrosato@linux.ibm.com>

We now receive the hardware identification of the PCI Function type
through vfio.  While we can't yet forward that to a guest via CLP,
we can still use this to make device-type-dependent decisions in
QEMU.
