Until recently, even when the getty generator was disabled in the
systemd recipe it was actually still active. This was because the old
behaviour was to delete the serial-getty template unit if the generator
was disabled, but the systemd-serialgetty package shipped then shipped
the same files so the generator continued to run. This was a bug in the
original commit[1] so this behaviour has been present since 2016.
My recent fixes[2] changed this: if the getty generator was disabled
then the generator itself is deleted. This makes the actual behaviour
match the intention, but the consequence was to demonstrate that some
modern platforms were relying on this unexpected behaviour: specifically
the genericarm64 BSP which intends to support a number of virtual and
physical boards with a number of serial console ports that are not
really suitable to be hardcoded into SERIAL_CONSOLES:
- ttyS0
- ttyAMA0 (AMBA PL011 uart)
- ttyS2 (BeagleBone Play, S0 and S1 are internal)
- hvc0 (KVM)
- ttyPS1 (AMD KV260)
- And most likely more
Restore the existing behaviour by explicitly enabling the serial getty
generator: this means that systemd will automatically bring up a getty
on the first serial console it finds.
In the future we should extend some level of dynamic console-finding to
sysvinit-based systems by searching for a console device in inittab, but
for now this reverts the unintentional regression.

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.
