ti: Add more packages and make weston the OOB #8375
Conversation
WalkthroughThis change updates board configuration files for SK-AM62B and SK-AM64B by introducing new configuration variables, including SoC identifiers and support flags for GPU, video output, Chromium, and additional firmware packages. The global TI package list in the K3 family configuration is expanded to include essential packages and conditionally appends GPU, video output, Chromium, and extra board-specific packages. Two new functions are added to the TI Debian packaging extension: one for user/service setup and configuration deployment, and another for activating DKMS modules after kernel installation. New configuration and PAM files are introduced for the emptty TTY manager and Weston compositor. The package list in the common CLI configuration is updated to include the Estimated code review effort🎯 2 (Simple) | ⏱️ ~7 minutes Suggested labels

8-9: Consider uncommenting user/group settings for security.Running Weston as root (implied by the commented user/group settings) may not be ideal from a security perspective. Consider uncommenting and using dedicated users if they exist on the system.

40-40: Consider making Weston backend configurableThe service hard-codes the DRM backend with specific options. Consider making the backend and options configurable through the environment file for better flexibility across different hardware configurations.

Learning: In the Armbian build system, package transitions in Debian/Ubuntu don't happen uniformly across all releases. For example, the transition from plasma-workspace-wayland to plasma-workspace occurred in newer releases like trixie (Debian testing) around July 2024, but older releases like jammy (Ubuntu 22.04) still maintain the original plasma-workspace-wayland package. Release-specific package availability must be considered when updating package references.

Fix socket path mismatch with environment configuration.
The socket path /run/wayland-0 doesn't match the WAYLAND_DISPLAY=wayland-1 setting in the weston environment file. This will cause connection failures.
Choose one of these solutions:
- Change the socket path to match the display name:

In packages/bsp/ti/weston/weston.socket at line 6, the socket path
ListenStream=/run/wayland-0 does not match the WAYLAND_DISPLAY=wayland-1
environment setting, causing connection failures. Fix this by either updating
the socket path to /run/wayland-1 to match the environment variable or change
the WAYLAND_DISPLAY environment variable to wayland-0 to match the socket path,
ensuring both are consistent.

Security concern: Running Weston as root user
Running the Weston compositor as root presents significant security risks. Display servers typically run with lower privileges for security isolation. Consider creating a dedicated user account for Weston or using a login manager that can handle privilege separation.
Consider this approach instead:
-User=root
-Group=root
+User=weston
+Group=westonAnd ensure the weston user is created with appropriate permissions for accessing graphics hardware.

However, no /etc/default/weston is present in the repo or packaging. This can cause the service to fail or skip needed settings.

Include the default environment file
Add a file (e.g.packages/bsp/ti/weston/weston.env) and install it to/etc/default/westonwith the necessary variables for Weston. -

Starting Weston as a root systemd service was a hack we did for our Yocto SDK distro, it was not correct and we are switching to using a proper weston user and launching with a login-manager (Emptty). For Armbian you should do the same or re-use GDM or similar default manager to launch a weston session. |
|
@glneo Understood. I am going with emptty, and got it working using the upstream emptty package. Do we want auto-login into weston like in our Yocto-based SDK, or do we want to show the username/password screen? I am wondering since the first boot takes you through the armbian-firstlogin script setup anyway. For now, I have gone with auto-login. If you think the alternative is better, I will update the PR. |

Currently, this is the case with AM62SIP and AM62LP. This is due to memory constraints (at least in case of SIP).

Done.
assumed to be true
The files in lib/ just check if its set to "no", but don't check if its "yes" anywhere (i.e. they don't really initialize it anywhere to "yes"). So I have set it to "yes" explicitly in sk-am62b.conf.

I think it would be easier to assume it to be true in the check you are adding, only one of our boards will have it set as "no", for all others just add the display support.

$SRCand$SDCARDare unquoted inside thecp/mkdircommand strings.
A pathname with spaces (rare, but possible in$SRC) would break the command passed to the host shell.The Weston/Emptty configuration copies can be compacted, but more importantly, should be fully quoted:
- run_host_command_logged "cp -v $SRC/packages/bsp/ti/emptty/weston.ini $SDCARD/etc/xdg/weston/" + run_host_command_logged "cp -v \"${SRC}/packages/bsp/ti/emptty/weston.ini\" \"${SDCARD}/etc/xdg/weston/\""(repeat for the other two

- Double-check that Emptty actually expects its main config at
/etc/emptty/conf.
Upstream recently switched the default to/etc/emptty/emptty.conf; if that’s the case the copy target should be updated accordingly.

Learning: In the Armbian build system, package transitions in Debian/Ubuntu don't happen uniformly across all releases. For example, the transition from plasma-workspace-wayland to plasma-workspace occurred in newer releases like trixie (Debian testing) around July 2024, but older releases like jammy (Ubuntu 22.04) still maintain the original plasma-workspace-wayland package. Release-specific package availability must be considered when updating package references.

Make user/group creation idempotent to avoid hard-failures on rebuilds
groupadd and useradd abort with non-zero exit codes when the entity already exists.
Because chroot_sdcard executes with set -e, a rebuild or a base image that already ships the nopasswdlogin group (or a weston user) will terminate the whole build.

- chroot_sdcard "useradd -m -s /bin/bash weston"

commands are not idempotent and will fail if the group or user already exists,
causing the build to terminate. Modify the script to first check if the group
'nopasswdlogin' exists before attempting to add it, and similarly check if the
user 'weston' exists before adding. Also, ensure that the auxiliary groups
'video', 'render', 'input', and 'nopasswdlogin' exist before running usermod to
add the user to these groups, creating any missing groups as needed to prevent

My rationale is: our boards are for evaluating and prototyping with our SoCs. If our SoC supports camera, then our image should ideally have by-default whatever it needs to run the camera. Our docs run the camera with GStreamer, which is why I added these. We had these in our previous flavour of Debian as well.

Same answer, but adapted to showing off GPU acceleration with browser. We had this in previous Debian, and also have it as a demo in our docs.
But I can remove both GStreamer and Chromium, if you disagree with this
Default and officially supported TI images will be the console image with emptty (display manager) running weston on top of it. Therefore add weston and emptty in the list of packages to install. Also, for emptty, change the conffile `/etc/pam.d/emptty`. Debian allows editing these files [0]. Further, add an explicit step to bind dkms packages to kernel. Currently the dkms package gets installed before the kernel, therefore if this step is excluded, the binding would occur on first boot, which would cause the first boot time to get longer. Therefore add the "dkms autoinstall" step. Additionally, add firmware, gstreamer, chromium etc packages.

Description
Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change.
TI Debian images support different features, such as IPC, Weston (as OOB screen), GPU acceleration, camera etc. So to have these working by-default in our images, this PR adds certain packages such as:
Additionally, there are 2 more things done here:
/lib/systemd/system/. This is to start weston on boot by-default. Note that weston doesn't launch on first boot when the armbian-firstlogin script runs, but starts launching from subsequent boots.dkms autoinstallbuilds and installs the ti-img-rogue--dkms package for the current kernel. If this isn't done here, it will done during first boot, which would make the first boot very slow.How Has This Been Tested?
Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.
