Add a test that verifies that each core properly displays the Raspberry Pi logo on the framebuffer device.
We simply follow the OpenCV "Template Matching with Multiple Objects" tutorial, replacing Lionel Messi by a raspberrry: 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 --show=app,framebuffer run -t device:bcm2835-fb tests/acceptance/ JOB ID : 9bbbc54c0a6fa180348d0b5305507f76852b4da2 JOB LOG : avocado/job-results/job-2020-01-31T23.48-9bbbc54/job.log (1/1) tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_raspi2_framebuffer_logo: framebuffer: found raspberry at position (x, y) = (0, 0) framebuffer: found raspberry at position (x, y) = (71, 0) framebuffer: found raspberry at position (x, y) = (142, 0) framebuffer: found raspberry at position (x, y) = (213, 0) PASS (11.06 s) RESULTS : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0 JOB TIME : 11.39 s Signed-off-by: Philippe Mathieu-Daudé <f4...@amsat.org> --- The resulting match can be visualised at https://pasteboard.co/ISzNHtx.png --- tests/acceptance/boot_linux_console.py | 62 ++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) diff --git a/tests/acceptance/boot_linux_console.py b/tests/acceptance/boot_linux_console.py index e40b84651b..4e69a83a12 100644 --- a/tests/acceptance/boot_linux_console.py +++ b/tests/acceptance/boot_linux_console.py @@ -12,6 +12,7 @@ import os import lzma import gzip import shutil +import logging from avocado import skipUnless from avocado_qemu import Test @@ -21,6 +22,19 @@ from avocado.utils import process from avocado.utils import archive +NUMPY_AVAILABLE = True +try: + import numpy as np +except ImportError: + NUMPY_AVAILABLE = False + +CV2_AVAILABLE = True +try: + import cv2 +except ImportError: + CV2_AVAILABLE = False + + class BootLinuxConsole(Test): """ Boots a Linux kernel and checks that the console is operational and the @@ -360,6 +374,54 @@ class BootLinuxConsole(Test): """ self.do_test_arm_raspi2(0) + @skipUnless(NUMPY_AVAILABLE, 'Python NumPy not installed') + @skipUnless(CV2_AVAILABLE, 'Python OpenCV not installed') + def test_arm_raspi2_framebuffer_logo(self): + """ + :avocado: tags=arch:arm + :avocado: tags=machine:raspi2 + :avocado: tags=device:bcm2835-fb + """ + screendump_path = os.path.join(self.workdir, 'screendump.pbm') + rpilogo_url = ('https://github.com/raspberrypi/linux/raw/' + 'raspberrypi-kernel_1.20190517-1/' + 'drivers/video/logo/logo_linux_clut224.ppm') + rpilogo_hash = 'fff3cc20c6030acce0953147f9baac43f44ed6b0' + rpilogo_path = self.fetch_asset(rpilogo_url, asset_hash=rpilogo_hash) + deb_url = ('http://archive.raspberrypi.org/debian/' + 'pool/main/r/raspberrypi-firmware/' + 'raspberrypi-kernel_1.20190215-1_armhf.deb') + deb_hash = 'cd284220b32128c5084037553db3c482426f3972' + deb_path = self.fetch_asset(deb_url, asset_hash=deb_hash) + kernel_path = self.extract_from_deb(deb_path, '/boot/kernel7.img') + dtb_path = self.extract_from_deb(deb_path, '/boot/bcm2709-rpi-2-b.dtb') + + self.vm.set_console() + kernel_command_line = (self.KERNEL_COMMON_COMMAND_LINE + + 'earlycon=pl011,0x3f201000 console=ttyAMA0') + self.vm.add_args('-kernel', kernel_path, + '-dtb', dtb_path, + '-append', kernel_command_line) + self.vm.launch() + framebuffer_ready = 'Console: switching to colour frame buffer device' + wait_for_console_pattern(self, framebuffer_ready) + self.vm.command('human-monitor-command', command_line='stop') + self.vm.command('human-monitor-command', + command_line='screendump %s' % screendump_path) + logger = logging.getLogger('framebuffer') + + cpu_cores_count = 4 + match_threshold = 0.95 + screendump_bgr = cv2.imread(screendump_path, cv2.IMREAD_COLOR) + rpilogo_bgr = cv2.imread(rpilogo_path, cv2.IMREAD_COLOR) + result = cv2.matchTemplate(screendump_bgr, rpilogo_bgr, + cv2.TM_CCOEFF_NORMED) + loc = np.where(result >= match_threshold) + rpilogo_count = 0 + for rpilogo_count, pt in enumerate(zip(*loc[::-1]), start=1): + logger.debug('found raspberry at position (x, y) = %s', pt) + self.assertGreaterEqual(rpilogo_count, cpu_cores_count) + def test_arm_exynos4210_initrd(self): """ :avocado: tags=arch:arm -- 2.21.1
