Viewing real time ltt trace using gtkwave
This presentation will explain how to use some ltt to be viewd in gtkwave, a graphical visualization tool, developped by the Parrot team.
It will also explain why this tool was developed, review some of the problems that have been analyzed using these traces. It will finally end up on the ongoing integration with LTTng 2.x.

Easy rootfs using Buildroot
The Linux kernel is an exciting world. But if you want to get a working system, it is still essential to provide our kernel a root filesystem. The kernel developers often struggle to find a simple rootfs, adapted to their architecture, together with the tools that fits properly.
We will present how Buildroot, a tool for building embedded Linux systems, can meet the needs of kernel developers in the build of minimal rootfs for their developments.

kconfig-frontends, a packaging of the kconfig parser and frontends
The configuration language used by the Linux kernel, known as kconfig, has gained some traction in the community, and is increasingly used by third-party projects. The kconfig-frontends package aims at centralising the effort of keeping an up-to-date, out of the Linux source tree, packaging of the kconfig infrastructure, ready for use by third party projects.
The state of the project will be presented: what has been done so far, and ideas on future evolutions. Some kconfig tips and tricks will also be demonstrated.

Conditional boot
When booting the same Linux Kernel over various hardware setups, it could necessary to add some arguements on the command line. Usually, people solve this issue by adding a new boot entry which features the necessary arguments.
This lightning talk will be demontrating how Syslinux can add dynamically arguments to the command line or even choose a different kernel regarding some hardware properties.

Persistent logs using UBI
A short presentation about a library for persistent log based on the UBI layer. The goal is to enable an embedded software component to log persistent messages (even after a full update of the system) without requiring the use of a file system.
