As per the discussion on https://lore.kernel.org/qemu-devel/87sfdpqcy4.fsf@linaro.org/ it was mentioned that the baseline test for ppc64 could be modified to make up this 2% code coverage. This patch attempts to achieve this 2% code coverage by adding various device command line arguments (to ./qemu-system-ppc64) in the tuxrun_baselines.py test-case. The code coverage report with boot_linux.py, without it and finally with these tuxrun_baselines.py changes is as follows: With boot_linux.py ------------------ lines......: 13.8% (58006 of 420997 lines) functions..: 20.7% (7675 of 36993 functions) branches...: 9.2% (22146 of 240611 branches) Without boot_linux.py (without this patch changes) -------------------------------------------------- lines......: 11.9% (50174 of 420997 lines) functions..: 18.8% (6947 of 36993 functions) branches...: 7.4% (17580 of 239017 branches) Without boot_linux.py (with this patch changes) ----------------------------------------------- lines......: 13.8% (58287 of 420997 lines) functions..: 20.7% (7640 of 36993 functions) branches...: 8.4% (20223 of 240611 branches) Rebased on Alex Benee's testing/next branch: https://gitlab.com/stsquad/qemu/-/tree/testing/next Signed-off-by: Kautuk Consul Reported-by: Alex Bennée Reviewed-by: Harsh Prateek Bora Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Alex Bennée Message-Id: <20230424041830.1275636-1-kconsul@linux.vnet.ibm.com> Message-Id: <20230424092249.58552-13-alex.bennee@linaro.org> diff --git a/tests/avocado/tuxrun_baselines.py b/tests/avocado/tuxrun_baselines.py index e8749717e9..3a46e7a745 100644 --- a/tests/avocado/tuxrun_baselines.py +++ b/tests/avocado/tuxrun_baselines.py @@ -11,6 +11,7 @@ import os import time +import tempfile from avocado import skip, skipIf from avocado_qemu import QemuSystemTest @@ -72,6 +73,8 @@ def setUp(self): # Occasionally we need extra devices to hook things up self.extradev = self.get_tag('extradev') + self.qemu_img = super().get_qemu_img() + def wait_for_console_pattern(self, success_message, vm=None): wait_for_console_pattern(self, success_message, failure_message='Kernel panic - not syncing', @@ -179,6 +182,63 @@ def common_tuxrun(self, self.vm.launch() self.run_tuxtest_tests(haltmsg) + def ppc64_common_tuxrun(self, sums, prefix): + # add device args to command line. + self.vm.add_args('-netdev', 'user,id=vnet,hostfwd=:127.0.0.1:0-:22', + '-device', 'virtio-net,netdev=vnet') + self.vm.add_args('-netdev', '{"type":"user","id":"hostnet0"}', + '-device', '{"driver":"virtio-net-pci","netdev":' + '"hostnet0","id":"net0","mac":"52:54:00:4c:e3:86",' + '"bus":"pci.0","addr":"0x9"}') + self.vm.add_args('-device', '{"driver":"qemu-xhci","p2":15,"p3":15,' + '"id":"usb","bus":"pci.0","addr":"0x2"}') + self.vm.add_args('-device', '{"driver":"virtio-scsi-pci","id":"scsi0"' + ',"bus":"pci.0","addr":"0x3"}') + self.vm.add_args('-device', '{"driver":"virtio-serial-pci","id":' + '"virtio-serial0","bus":"pci.0","addr":"0x4"}') + self.vm.add_args('-device', '{"driver":"scsi-cd","bus":"scsi0.0"' + ',"channel":0,"scsi-id":0,"lun":0,"device_id":' + '"drive-scsi0-0-0-0","id":"scsi0-0-0-0"}') + self.vm.add_args('-device', '{"driver":"virtio-balloon-pci",' + '"id":"balloon0","bus":"pci.0","addr":"0x6"}') + self.vm.add_args('-audiodev', '{"id":"audio1","driver":"none"}') + self.vm.add_args('-device', '{"driver":"usb-tablet","id":"input0"' + ',"bus":"usb.0","port":"1"}') + self.vm.add_args('-device', '{"driver":"usb-kbd","id":"input1"' + ',"bus":"usb.0","port":"2"}') + self.vm.add_args('-device', '{"driver":"VGA","id":"video0",' + '"vgamem_mb":16,"bus":"pci.0","addr":"0x7"}') + self.vm.add_args('-object', '{"qom-type":"rng-random","id":"objrng0"' + ',"filename":"/dev/urandom"}', + '-device', '{"driver":"virtio-rng-pci","rng":"objrng0"' + ',"id":"rng0","bus":"pci.0","addr":"0x8"}') + self.vm.add_args('-object', '{"qom-type":"cryptodev-backend-builtin",' + '"id":"objcrypto0","queues":1}', + '-device', '{"driver":"virtio-crypto-pci",' + '"cryptodev":"objcrypto0","id":"crypto0","bus"' + ':"pci.0","addr":"0xa"}') + self.vm.add_args('-device', '{"driver":"spapr-pci-host-bridge"' + ',"index":1,"id":"pci.1"}') + self.vm.add_args('-device', '{"driver":"spapr-vscsi","id":"scsi1"' + ',"reg":12288}') + self.vm.add_args('-m', '2G,slots=32,maxmem=4G', + '-object', 'memory-backend-ram,id=ram1,size=1G', + '-device', 'pc-dimm,id=dimm1,memdev=ram1') + + # Create a temporary qcow2 and launch the test-case + with tempfile.NamedTemporaryFile(prefix=prefix, + suffix='.qcow2') as qcow2: + process.run(self.qemu_img + ' create -f qcow2 ' + + qcow2.name + ' 1G') + + self.vm.add_args('-drive', 'file=' + qcow2.name + + ',format=qcow2,if=none,id=' + 'drive-virtio-disk1', + '-device', 'virtio-blk-pci,scsi=off,bus=pci.0,' + 'addr=0xb,drive=drive-virtio-disk1,id=virtio-disk1' + ',bootindex=2') + self.common_tuxrun(csums=sums, drive="scsi-hd") + # # The tests themselves.
