[PATCH 0/2] tests/acceptance/integratorcp: Verify Tux is displayed on framebuffer

[Philippe Mathieu-Daudé]

Hi,

This is a simple Avocado test that use OpenCV to find the
Tux logo on the framebuffer screen dump.

It is very fast, around 4 seconds on my laptop.

Tux found by OpenCV: https://pasteboard.co/ISz7kr8.png

Regards,

Phil.

[PATCH 1/2] tests/acceptance: Extract boot_integratorcp() from test_integratorcp()

[Philippe Mathieu-Daudé]

As we want to re-use this code, extract it as a new function.
Since we are using the PL011 serial console, add a Avocado tag
to ease filtering of tests.

I wonder whether you might want to move the "console=ttyAMA0" to the
test_integratorcp(), too, to get the text in the framebuffer in the
second test instead?

This is not a test, but a common method used by both tests, so both use it.

Thanks!

Peter, Thomas previous patch and these series are reviewed. Can you 
queue them in your target-arm.next tree?

[PATCH 2/2] tests/acceptance/integratorcp: Verify Tux is displayed on framebuffer

[Philippe Mathieu-Daudé]

Add a test that verifies the Tux logo is displayed on the framebuffer.

We simply follow the OpenCV "Template Matching with Multiple Objects"
tutorial, replacing Lionel Messi by Tux:
https://docs.opencv.org/4.2.0/d4/dc6/tutorial_py_template_matching.html

When OpenCV and NumPy are installed, this test can be run using:

  $ AVOCADO_ALLOW_UNTRUSTED_CODE=hmmm \
    avocado --show=app,framebuffer run -t device:framebuffer \
      tests/acceptance/machine_arm_integratorcp.py

What a cool idea :-)

If you like, there are some more images with Tux in the QEMU advent
calendar 2018 which you could use for testing the framebuffer:

 https://www.qemu-advent-calendar.org/2018/download/day13.tar.xz
 https://www.qemu-advent-calendar.org/2018/download/day15.tar.xz
 https://www.qemu-advent-calendar.org/2018/download/day16.tar.xz
 https://www.qemu-advent-calendar.org/2018/download/day19.tar.xz

These two use a slightly different tux:

 https://www.qemu-advent-calendar.org/2018/download/day09.tar.xz
 https://www.qemu-advent-calendar.org/2018/download/day11.tar.xz

And day 22 (MIPS64) and 23 (SPARC64) use a framebuffer, too, but they
seem to be broken with the current version from the git master branch.
