Thus this test requires the QEMU binary to be compiled with: $ configure ... --enable-trace-backends=log This test also requires the dpkg-deb tool (apt/dnf install dpkg) to extract the kernel from the Debian package. $ avocado --show=app,trace run -p arch=sh4 tests/acceptance/boot_linux_console.py JOB ID : dc45be27f5d1edb8289a1ede139e107bbc55b045 JOB LOG : /home/phil/avocado/job-results/job-2018-10-13T14.46-dc45be2/job.log (1/5) tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_x86_64_pc: CANCEL: Currently specific to the x86_64 target arch (0.00 s) (2/5) tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_mips_4kc_malta: CANCEL: Currently specific to the sh4 target arch (0.00 s) (3/5) tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_mipsel_5kc_malta: CANCEL: Currently specific to the sh4 target arch (0.00 s) (4/5) tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_sh4_r2d: SKIP: console not working on r2d machine (5/5) tests/acceptance/boot_linux_console.py:BootLinuxTracing.test_sh4_r2d: / trace: 22770@1539434809.450006:usb_ohci_init_time usb_bit_time=1000000 usb_frame_time=83 trace: 22770@1539434809.453017:usb_ohci_port_attach port #0 trace: 22770@1539434809.454827:usb_ohci_reset sysbus-ohci trace: 22770@1539434809.454833:usb_ohci_stop sysbus-ohci: USB Suspended trace: 22770@1539434809.454835:usb_ohci_stop sysbus-ohci: USB Suspended trace: 22770@1539434809.454837:usb_ohci_port_detach port #0 trace: 22770@1539434809.454839:usb_ohci_port_attach port #0 trace: 22770@1539434811.588702:usb_ohci_reset sysbus-ohci trace: 22770@1539434811.588711:usb_ohci_stop sysbus-ohci: USB Suspended trace: 22770@1539434811.589062:usb_ohci_set_ctl sysbus-ohci: new state 0x80 trace: 22770@1539434811.589067:usb_ohci_start sysbus-ohci: USB Operational trace: 22770@1539434811.589253:usb_ohci_hub_power_up powered up all ports PASS (2.43 s) RESULTS : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 3 JOB TIME : 2.67 s Signed-off-by: Philippe Mathieu-Daudé --- tests/acceptance/boot_linux_console.py | 64 ++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) diff --git a/tests/acceptance/boot_linux_console.py b/tests/acceptance/boot_linux_console.py index 8f99cc0d7c..e11993bf98 100644 --- a/tests/acceptance/boot_linux_console.py +++ b/tests/acceptance/boot_linux_console.py @@ -8,11 +8,22 @@ # This work is licensed under the terms of the GNU GPL, version 2 or # later.
