For the past couple of days I’ve been attending the first ever sprint held by the Linaro Tools and Infrastructure team. The sprint itself lasts all week but I arranged to be there for just Tuesday and Wednesday to find out what they had planned and to join up with a few guests.

This event is slightly different from what we typically do at Ubuntu sprints. The team hasn’t been together for that long so there was equal focus on both information sharing and collaboration. To that end, mornings were for presentations and discussion, afternoons for hands-on hacking.

A link to the whole schedule is here; for my account of what happened whilst I was there, read on.

Tuesday started with a discussion on image building by Michael Hudson. Often lively and full of good information, the key steps to producing the Linaro images was the focus of conversation. Two launchpad specifications cover this effort, the first, arm-m-image-building-tool concerns improving live-helper to accommodate Linaro’s needs, the second, arm-m-image-building-console aims to produce a web based front-end for the image building tools.

Zygmunt Krynicki‘s project entitled Validation Dashboard was next (slides can be found here). An ambitious project to produce a front end visual representation for various testing tools; this effort is of great importance as validation and correctness is paramount to the software releases Linaro makes.

Another requirement for Linaro is the ability to branch and rebuild parts of the Ubuntu archive. Linaro benefits from the great effort that is put into the Ubuntu archive but as Linaro’s needs are at times, different, being able to diverge without affecting Ubuntu itself is important. This effort is being lead by James Westby.

Tuesday morning finished with Paul Larson‘s testsuite and profiler presentation. Closely related to Zygmunt’s dashboard effort, Paul is working on combing the various testsuites and profiles into one big validation effort.

At this point the guys from Code Sourcery joined us to discuss toolchain’s and related tools. Will Deacon, Matthias Klose and David Rusling joined the conversation and many points were ironed out. Linaro will benefit from the great work Code Sourcery do around GCC and related tools, producing what we think will be the industry standard tool chain for ARM based devices. A lofty goal but everyone behind the effort is confident.

Talk on tools and toolchains continued to be the focus for the rest of Tuesday and Wednesday. Code Sourcery went away with a pile of work items and the Linaro members todo lists were equally full. There was just enough time Wednesday to sit down with Dave Rusling to formally sign off the technical requirements.

As one Linux Weekly News author put it,

the list of planned achievements for the five months before the release is quite ambitious … even completing a big chunk of it would be quite an accomplishment

We believe we can do it and with the great individuals such as those at the sprint this week, the 10.11 release will be something special.
