Yocto Buildsystem

Migrating to Yocto: A guide and lessons learned

Presenter: Muhammad Tauqir Ahmad, Cisco Meraki
Summary: The session talks about the lessons learnt while migrating to the new system,
including the technical challenges like supporting proprietary software on Yocto, verifying
correctness of the builds produced by the new build system, accommodating the various
use cases, as well as human aspects of such a large migration like getting buy-in from
stakeholders, documenting process and maintenance.

Sweeten your Yocto Build Times with Icecream

Presenter:Joshua Watt, Garmin International
Summary: Yocto takes a considerable amount of time to build complex systems and hence,
a lot of time is spent waiting for builds to complete.One method of accelerating these
builds is to use a distributed compiler such as Icecream. The presenter discusses the
current state of Icecream support in Yocto, pros and cons of using Icecream, typical
configurations, as well as tips, tricks, and quirks he has learned while using Icecream.

Working with the Linux Kernel in the Yocto Project

Presenter:Sean Hudson, The Yocto Project
Summary: The slides cover an example recipe to add the Kernel to the build and talks
about the best practices and the work flows to create a custom kernel for their
distribution. The talk also explores the development cycle of creating a new
kernel configuration and integrating it fully back into the platform.

Bitbake

Top 3 pains in professional use of bitbake

Presenter: Klaas van Gend
Summary: This presentation will give an idea about the usage of bitbake for
OpenEmbedded platforms and how Bitbake fits into professional use
better than "Linux from Scratch” and how community knowledge can be
leveraged.

Buildroot

Buildroot V/s OpenEmbedded/Yocto: A Four Hands Discussion

Presenter: Alexandre Belloni & Thomas Petazzoni, Free Electrons
Summary: This presentation compares the general philosophy, output, configuration,
layers, tool-chains, packages and complexity of both Buildroot and Yocto for
Embedded Linux platforms.
