Both nodes produce virtio-balloon, but virtio-balloon-pci receives a pci-bus and uses virtio-pci QOSGraphObject and functions, while virtio-balloon-device receives a virtio and implements its own functions Signed-off-by: Emanuele Giuseppe Esposito Signed-off-by: Paolo Bonzini --- tests/Makefile.include | 1 + tests/libqos/virtio-balloon.c | 113 ++++++++++++++++++++++++++++++++++++++++++ tests/libqos/virtio-balloon.h | 39 +++++++++++++++ 3 files changed, 153 insertions(+) create mode 100644 tests/libqos/virtio-balloon.c create mode 100644 tests/libqos/virtio-balloon.h diff --git a/tests/Makefile.include b/tests/Makefile.include index 2a531df..d31aade 100644 --- a/tests/Makefile.include +++ b/tests/Makefile.include @@ -672,6 +672,7 @@ qos-test-obj-y += tests/libqos/e1000e.o qos-test-obj-y += tests/libqos/sdhci.o qos-test-obj-y += $(libqos-virtio-obj-y) qos-test-obj-y += tests/libqos/virtio-9p.o +qos-test-obj-y += tests/libqos/virtio-balloon.o qos-test-obj-y += tests/libqos/virtio-serial.o # Machines diff --git a/tests/libqos/virtio-balloon.c b/tests/libqos/virtio-balloon.c new file mode 100644 index 0000000..7e6e9e9 --- /dev/null +++ b/tests/libqos/virtio-balloon.c @@ -0,0 +1,113 @@ +/* + * 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.
