Subject: [PATCH v3] kconfig: Add PCIe devices to s390x machines
Date: Wed,  5 Jul 2023 17:23:01 +0200	[thread overview]
Message-ID: <20230705152301.2850086-1-clg@redhat.com> (raw)

It is useful to extend the number of available PCI devices to KVM guests
for passthrough scenarios and also to expose these models to a different
(big endian) architecture. Include models for Intel Ethernet adapters
and one USB controller, which all support MSI-X. Devices only supporting
INTx won't work on s390x.
