This takes the work rburton did on image screenshot testing and
expands it.
Right now this works with most of the qemu based machines except for
- qemuppc64
- qemuarmv5
- qemuriscv32
- qemuloongarch64
See "Known Issues" further down.
This test takes a screendump of a qemu image, blanks out the clock
and compares it to an image we have on record. If the diff is exact,
the test passes. If not, it stores the image in build/failed-images and
fails out.
In order to enable this test, you will need meta-openembedded/meta-oe in
your bblayers.conf for imagemagick and the following in local.conf:
IMAGE_CLASSES += "testimage"
TEST_SUITES = "login"
TESTIMAGEDEPENDS:append:qemuall = " imagemagick-native:do_populate_sysroot "
Known Issues
------------
The main issue is that I've yet to find a gating factor that would allow
me to tell when the qemu instance is fully up and rendered. I've tried a
few tactics here, (dbus-wait, qmp) but for now a disgusting
time.sleep(30) is there.
You can replicate this by running qemumips. The screen load takes forever,
but you even see it on qemux86 where the Home and Workspace Switch icons
will sometimes take a while to fully load.
Eventually I'm going to have to take multiple screenshots and compare
them, but then you get into the issue where the question is, is the diff
greater than 0 because it hasn't fully loaded or something is actually
incorrect.
There are the issues I know about:
- runqemu qemuppc64 comes up blank.
- qemuarmv5 comes up with multiple heads but sending "head" to screendump.
seems to create a png with a bad header.
- qemuriscv32 and qemuloongarch64 don't work with testimage apparently?
- qemumips64 is missing mouse icon.
- qemumips takes forever to render and is missing mouse icon.
- qemuarm and qemuppc return incorrect width
- All images have home and screen flipper icons not always rendered fully at first.
The sleep seems to help this out some, depending on machine load.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.
Contribution Guidelines
Please refer to our contributor guide here: https://docs.yoctoproject.org/dev/contributor-guide/ for full details on how to submit changes.
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
