TorizonCore 5.4.0 Quarterly Release
TorizonCore is our operating system that powers Torizon, a DevOps platform that simplifies the development and maintenance of embedded Linux software. TorizonCore is designed to be used out-of-the-box on devices requiring high reliability, allowing you to focus on your application instead of on building and maintaining an operating system.
Torizon uses software containers, making it simple to add functionality to your system in a way that is both secure and easy to maintain. Torizon supports hardware acceleration in containers and graphical user interfaces.
This release includes all updates from the previous 5.x.y TorizonCore releases.
Updates and Highlights
- Boot time optimization
This release of TorizonCore boots several seconds faster than on previous releases. The optimizations have a positive impact on all supported SoMs.
Read our article TorizonCore Boot Time Optimization to learn more; including the current boot time measurements, how to measure the boot time by yourself, and how to further optimize the boot time for your specific use case.
- Device monitoring enabled by default
Device monitoring is a feature requested by many of our customers. It makes it possible to check the health and monitor the performance of a device running TorizonCore.
Fluent Bit is the log processor and forwarder that runs on TorizonCore and sends data to populate the remote monitoring service from the Torizon Platform.
Learn more about this feature in our article Device Monitoring in TorizonCore.
- Container monitoring and recovery from Docker container corruption
To improve the reliability of systems based on TorizonCore, we have added a Systemd service that automatically attempts to recover the system if containers fail to start. This feature is currently disabled by default and you must enable it.
An additional Systemd service allows you to add your own health checks to validate that running containers behave as expected.
Learn more about those two features in the article Reliability on Torizon.
- Base OS & containers synchronous updates
The Torizon Platform enables two distinct types of remote updates:
- OS: updates the base TorizonCore image
- Application: updates the containerized applications
From this release on, you can send both OS and application as a single update.
This guarantees that both, the OS and application, are updated successfully, thereby avoiding version mismatch between them. If one of them fails, both are rolled back to the previous state.
- New device drivers enabled by default
The AD5592, AD5593 and AD7124 device drivers are enabled as kernel modules.
You can use them by applying your custom device tree or device tree overlays with the TorizonCore Builder Tool.
- Easier debugging of Aktualizr-Torizon with more verbose log messages
It is possible to debug Aktualizr-Torizon with the help of Systemd's journalctl.
To produce richer debug messages, we have added new event results logging. The messages are printed as
Event: SomeEvent, Result - Some Result. See an example below:
- Update of TorizonCore packages
The following packages have been updated:
- Fluent-Bit updated from 1.7.3 to 1.8.3
- Podman (experimental) updated from 3.1.1 to 3.2.3
- Conmon updated from 2.0.18 to 2.0.29
- Fuse-overlayfs updated from 1.5.0 to 1.7.0
Debian Packages and Containers
- All containers rebuilt against the Debian Bullseye stable release
Bullseye has been released in its stable form on August 14th. We have stopped using snapshots and rebuilt our Docker images against their stable feeds.
- Hardware-accelerated browser support with Cog in the kiosk-mode-browser container
Cog is a single "window" launcher intended for applications that require a web browser on kiosk-mode. Cog leverages SoMs with GPU (i.MX 6 and i.MX 8 based modules). Currently, it doesn't work on devices that lack a GPU, like the i.MX 7.
If you have been using Chromium in your products, we encourage you to test Cog and provide feedback.
- Development containers open-sourced to GitHub
Two of our repositories were open-sourced and added to GitHub. They are the containers used in our Visual Studio and VS Code IDE Extensions for Torizon:
- Portainer updated from 2.1.1 to 2.6.2
Portainer is a user-friendly GUI for managing containers. This update does not have a significant impact on TorizonCore users.
- Several bug fixes
Browse through cumulative bug fixes from 5.4.0-devel-202108, 5.4.0-devel-202109 and 5.4.0.
