Note that it launches two instances to as sharing memory is the purpose of Nahanni/ivshmem.
Cc: Cam Macdonell <c...@cs.ualberta.ca> Signed-off-by: Andreas Färber <afaer...@suse.de> --- This test demonstrates a use case of running two QEMU instances in qtest. However, similar to mst's proposed KVM acpi-test, it fails on systems without KVM support, and we cannot use $(CONFIG_KVM) to make it conditional since that is a per-target define rather than host-wide. I wonder if libqtest should expose an API to start a QEMU instance and inquire via QMP whether the executable supports KVM, returning true or false? tests/Makefile | 3 +++ tests/ivshmem-test.c | 40 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 43 insertions(+) create mode 100644 tests/ivshmem-test.c diff --git a/tests/Makefile b/tests/Makefile index 6086f68..e4c3b12 100644 --- a/tests/Makefile +++ b/tests/Makefile @@ -137,6 +137,8 @@ check-qtest-i386-y += tests/pvpanic-test$(EXESUF) gcov-files-i386-y += i386-softmmu/hw/misc/pvpanic.c check-qtest-i386-y += tests/i82801b11-test$(EXESUF) gcov-files-i386-y += hw/pci-bridge/i82801b11.c +check-qtest-i386-y += tests/ivshmem-test$(EXESUF) +gcov-files-i386-y += i386-softmmu/hw/misc/ivshmem.c check-qtest-x86_64-y = $(check-qtest-i386-y) gcov-files-i386-y += i386-softmmu/hw/timer/mc146818rtc.c gcov-files-x86_64-y = $(subst i386-softmmu/,x86_64-softmmu/,$(gcov-files-i386-y)) @@ -287,6 +289,7 @@ tests/qdev-monitor-test$(EXESUF): tests/qdev-monitor-test.o $(libqos-pc-obj-y) tests/nvme-test$(EXESUF): tests/nvme-test.o tests/pvpanic-test$(EXESUF): tests/pvpanic-test.o tests/i82801b11-test$(EXESUF): tests/i82801b11-test.o +tests/ivshmem-test$(EXESUF): tests/ivshmem-test.o tests/qemu-iotests/socket_scm_helper$(EXESUF): tests/qemu-iotests/socket_scm_helper.o # QTest rules diff --git a/tests/ivshmem-test.c b/tests/ivshmem-test.c new file mode 100644 index 0000000..e981ad3 --- /dev/null +++ b/tests/ivshmem-test.c @@ -0,0 +1,40 @@ +/* + * QTest testcase for Nahanni + * + * Copyright (c) 2014 SUSE LINUX Products GmbH + * + * This work is licensed under the terms of the GNU GPL, version 2 or later. + * See the COPYING file in the top-level directory. + */ + +#include <glib.h> +#include <string.h> +#include "libqtest.h" +#include "qemu/osdep.h" + +/* Tests only initialization so far.
