Subject: [PATCH v2] kconfig: Add PCIe devices to s390x machines
Date: Tue, 4 Jul 2023 14:01:37 +0200 [thread overview]
Message-ID: <20230704120137.2604646-1-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.
Signed-off-by: Cédric Le Goater <clg@redhat.com>

Tested under KVM as a machine device, under KVM nested as a passthrough
device
