From ee1882452a6bbc1188d630a7cb997b21e3814254 Mon Sep 17 00:00:00 2001 From: Xiao Wang Date: Tue, 7 Jul 2015 09:18:58 +0200 Subject: [PATCH 170/217] virtio-input: emulated devices [pci] Message-id: <1436260751-25015-56-git-send-email-jasowang@redhat.com> Patchwork-id: 66830 O-Subject: [RHEL7.2 qemu-kvm-rhev PATCH V2 55/68] virtio-input: emulated devices [pci] Bugzilla: 1227343 RH-Acked-by: Michael S. Tsirkin RH-Acked-by: David Gibson RH-Acked-by: Laurent Vivier RH-Acked-by: Thomas Huth From: Gerd Hoffmann This patch adds virtio-pci support for the emulated virtio-input devices. Using them is as simple as adding "-device virtio-tablet-pci" to your command line. If you want add multiple devices but don't want waste a pci slot for each you can compose a multifunction device this way: qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \ -device virtio-tablet-pci,addr=0d.1,multifunction=on Signed-off-by: Gerd Hoffmann Reviewed-by: Michael S.
