Etnaviv-Unterstützung in Wayland Mainline
Wenn man der Entwicklung des Linux Grafikstacks folgt, konnte man in den letzten Wochen die Releases von MESA 17.2 und Weston 3.0 beobachten. Neben den üblichen Verbesserungen und Bugfixes für diverse Grafik-Hardware stellen diese aber auch einen wichtigen Meilenstein für das Etnaviv Projekt dar: mit diesen Releases gibt es vollständigen Support für Vivante-Grafikchips in Wayland!
Vortrag: Long Term Maintenance (Embedded Recipes)
Während die technische Seite der Erstellung von Embedded Linux Systemen ein weitgehend gelöstes Problem ist, wohnen dem Betrieb solcher Systeme mit Verbindung zum Internet über lange Zeiträume gewisse Herausforderungen inne.
PTXdist: Schon gewusst? Heute: Mal eben neu booten
Wer während der Entwicklung an einem embedded System selbiges immer wieder mal komplett neu starten muss, wird es zu schätzen wissen, wenn so wenig wie möglich getan werden muss, um bei veränderten Daten das System im konsistenten Zustand zu halten.
DistroKit - A Playground BSP for PTXdist
At Pengutronix we are using PTXdist to automatically integrate many industrial embedded Linux projects. Some time ago I started DistroKit: This example BSP shall be able to demonstrate PTXdist features.
PTXdist: Schon gewusst? Heute: Das Entwicklerleben verschönern
Es gibt Dinge, die machen das Leben als Entwickler einfacher - und schöner. Hier dazu ein Beispiel.
OSADL Networking Day 2017
In the last talk before lunch, my colleague Enrico Jörns talked about the RAUC (Robust Auto Update Controller) framework.
labgrid: Test Automation Framework Released
At Pengutronix, one of the most important tasks in our industrial linux projects is testing of embedded systems. While testing is easy on the component level (there are many unit test frameworks around), it is increasingly difficult on system level. Tests do not only run code and compare results, they need to bring the device-under-test into different states (i.e. "bootloader", "linux console", "power off"). If you have many embedded Linux devices, remote-controlling power, serial consoles, network, switches, reset lines, SD cards in scalable, automatic labs is also on the wishlist.
RAUC v0.1.1 released
RAUC is making progress, and my colleagues Enrico Jörns and Jan Lübbe finally pushed out a new release today that reflects what happened during the last months. Updating embedded linux systems in the field in a secure and robust way becomes more and more important; we had many interesting talks with our customers during the last time, and some of the new ideas are already finding their way into the codebase. However, there is still a lot of work ahead, and if you have more ideas, either drop us a note on the community channels, send patches or github pull requests, or ask for commercial help!
Chemnitz Linux Days 2017
In the first talk today, Michael Tretter reports about the current state of Open Source Graphics for Embedded Systems. For regular observers, it's probably not surprising that the focus will be on i.MX6, Etnaviv and the IPU.
Pengutronix Contributions to v4.10
Here is a short report about Pengutronix' contributions to the 4.10 kernel. It mainly contains more improvements for the i.MX6 graphics and video subsystem, Etnaviv, Marvell Orion and Altera SoCFPGA.
