- For QT apps to use physical keyboard, xkbcommon has to be
added in
PACKAGECONFIG. This was supported until 09.01 using xkbcommon-evdev which at
present is an invalid PACKAGECONFIG & hence was dropped from meta-arago [1].
- Hence, add xkbcommon to PACKAGECONFIG which will enable the
use of
physical keyboard in QT apps.

This would make the package machine-specific - why is it only applicable to k3?
For non k3 based platforms, with the removal of Matrix GUI I don't see
any QT Demos under meta-arago-demos which might need the keyboard
functionality [Ryan correct me if we have any QT demo applicable for
non k3 based platform which needs keyboard].
For k3 platforms, we have TI Apps Launcher (a QT based OOB demo) for which
xkbcommon is needed & hence I made this change machine specific.
That is a wrong reason to make a large package that many other packages depend
on (and build on top of) to be machine-specific! That will force qtbase to be
rebuilt from scratch for each and every K3 platform, instead of re-using
common Aarch64 binaries. Moreover, that invalidates sstate cache for all other
packages that depend on qtbase, essentially making them machine-specific as
well... In other words - keyboard support does not sound even remotely as a
machine-specific feature, so should rather be enabled or disabled globally on
a per-distro basis. And thus, should be set in distro config file.
Sorry for the late reply.
Valid point, I will send out a v2 patch adding it for all instead of making
it machine specific.
Btw, Denys do you have any background on why does meta-qt5 just in
case of Wayland doesn't
support this keyboard enablement by default though I see for x11
they add 'xkbcommon' in
PACKAGECONFIG by default [1]

Wayland support in Qt5 is provided by its QtWayland module and it handles
xkbcommon. Are there some corner cases you are trying to enable with this?
We are observing that without this patch, physical keyboards aren't
supported by QT Apps. Earlier meta-qt5 used to support that with
xkbcommon-evdev but currently it's an invalid PACKECONFIG. Hence, we
need xkbcommon which enables physical keyboards in QT Apps.
