Both nodes produce virtio-serial, but virtio-serial-pci receives a pci-bus and uses virtio-pci QOSGraphObject and functions, while virtio-serial-device receives a virtio and implements its own functions Signed-off-by: Emanuele Giuseppe Esposito --- tests/Makefile.include | 3 + tests/libqos/virtio-serial.c | 109 +++++++++++++++++++++++++++++++++++ tests/libqos/virtio-serial.h | 39 +++++++++++++ 3 files changed, 151 insertions(+) create mode 100644 tests/libqos/virtio-serial.c create mode 100644 tests/libqos/virtio-serial.h diff --git a/tests/Makefile.include b/tests/Makefile.include index d72d0d65b4..ad784a3e84 100644 --- a/tests/Makefile.include +++ b/tests/Makefile.include @@ -770,8 +770,11 @@ libqgraph-machines-obj-y +=3D tests/libqos/raspi2-mach= ine.o libqgraph-machines-obj-y +=3D tests/libqos/ppc64_pseries-machine.o libqgraph-machines-obj-y +=3D tests/libqos/virt-machine.o =20 +libqgraph-virtio-obj-y =3D tests/libqos/virtio-serial.o + libqgraph-pci-obj-y =3D $(libqos-virtio-obj-y) libqgraph-pci-obj-y +=3D $(libqgraph-machines-obj-y) +libqgraph-pci-obj-y +=3D $(libqgraph-virtio-obj-y) libqgraph-pci-obj-y +=3D tests/libqos/sdhci.o libqgraph-pci-obj-y +=3D tests/libqos/e1000e.o =20 diff --git a/tests/libqos/virtio-serial.c b/tests/libqos/virtio-serial.c new file mode 100644 index 0000000000..6dd4582d15 --- /dev/null +++ b/tests/libqos/virtio-serial.c @@ -0,0 +1,109 @@ +/* + * libqos driver framework + * + * Copyright (c) 2018 Emanuele Giuseppe Esposito + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License version 2 as published by the Free Software Foundation. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
