A libweston-based compositor for Automotive Grade Linux

June 02, 2021 by Marius Vlad  |   News & Events

Simplifying AGL's existing Wayland-based graphical stack and avoiding the use of modules that aren't maintained upstream has lead to the creation of a new compositor based on libweston, bringing more reliable and fine-grained system control.

Quick hack: Experiments with crosvm

November 09, 2017 by Tomeu Vizoso  |   Blog

Running crosvm outside Chromium OS is quite easy, with the only complication being that minijail isn't widely packaged in distros. In these instructions, we hack around the issue with linker environment variables so we don't have to install it properly.

Tracing memory leaks in the NFC Digital Protocol stack

November 06, 2017 by Thierry Escande  |   Blog

Kmemleak allows you to track possible memory leaks inside the Linux kernel. Basically, it tracks dynamically allocated memory blocks in the kernel and reports those without any reference left and that are therefore impossible to free.
