Commit c0c8687ef0fd990db8db1655a8a6c5a5e35dd4bb disabled the
boot_linux.py test-case due to which the code coverage for
powerpc decreased by 2%. This patchset aims to make up this
2% code coverage by modifying the tuxrun_baselines.py test-case.
Changes since v1 and v2:
- Modified the way and code that creates the temporary qcow2
image that the tuxrun_baselines.py is now using.
- Factored out code in avocado_qemu/__init__.py to create
the get_qemu_img() function that will now get called from
tuxrun_baselines.py.

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.

I kept it separate because there may be some future reason to make the devices different for ppc and ppc64le. I know that probably won't happen but thought to keep it separate to allow for that possibility. Or if you feel that they should be exactly the same maybe I could send another patch after this to refactor the code into a single routine ? > > regards, > Harsh > > + # Create a temporary qcow2 and launch the test-case > > + with tempfile.NamedTemporaryFile(prefix='tuxrun_ppc64_', > > + 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(drive="scsi-hd") > > > > def test_ppc64le(self): > > """ > > :avocado: tags=arch:ppc64 > > :avocado: tags=machine:pseries > > - :avocado: tags=cpu:POWER8 > > + :avocado: tags=cpu:POWER10 > > :avocado: tags=console:hvc0 > > :avocado: tags=tuxboot:ppc64le > > :avocado: tags=image:vmlinux > > :avocado: tags=extradev:driver=spapr-vscsi > > :avocado: tags=root:sda > > """ > > - self.common_tuxrun(drive="scsi-hd") > > + # 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='tuxrun_ppc64le_', > > + 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(drive="scsi-hd") > > > > def test_riscv32(self): > > """ > > -- > > 2.25.1 > > > > > > ^ permalink raw reply [flat|nested] 10+ messages in thread

I focused on just getting the lines' and functions' coverage equal to the boot_linux.py test-case. I just added devices to meet the coverage percentage and didn't really focus on imitating the code coverage that boot_linux.py does. > > Currently its only file granularity but it could be fixed up to do a > more detailed line by line breakdown.
