The 2013 Kernel Summit

The 2013 Kernel Summit was held October 23-25 in Edinburgh, UK. Following the pattern set in recent years, the 2013 summit was divided into a minisummit day (the 23rd), followed by a core-kernel, invitation-only session; a plenary day finished things out on the 25th. What follows is LWN's coverage from the event, supplemented in places with information posted by others.

The minisummit day

Several minisummits were held on the first day. Naturally, your editor was only able to attend one of them, being:

• Power-aware scheduling: how to improve CPU power management and tie it more firmly into the CPU scheduler.

Other minisummits held that day include:

• Media; notes posted by Mauro Carvalho Chehab.

• ARM architecture maintainers (Notes by Grant Likely).

The core day

The second day of the summit was attended by 70 or so invited developers. Topics covered this day include:

• The kernel/user-space boundary: where do we draw the line between the kernel and user space, especially when it comes to ABI guarantees?

• The Outreach Program for Women and the kernel.

• Control groups are under heavy development; this session covered where this subsystem is headed and the numerous issues that still need to be worked out.

• The linux-next and -stable trees; two sessions on our most important non-mainline trees.

• Testing: in particular, Trinity and Fenngguang Wu's build-and-boot test robot.

• On saying "no": are we accepting too much marginal code into the kernel?

• Bugzilla, lightning talks, and future summits. The status of the kernel's bug tracker, some random subjects, and discussion of the Kernel Summit itself.

The plenary day

A larger group met for the final day of the kernel summit. Among the topics discussed there were:

• Minisummit reports, with details from the ARM minisummit in particular.

• Git tree maintenance: how the tip and arm-soc trees are managed.

• Scalability techniques: four talks on the scalability mechanisms available in the kernel.

• Device tree bindings and how to resolve the current mess.

• Checkpoint/restart in user space; what is the status of this functionality?

• A kernel.org update; current and future changes to the community's development repository site.

• Security practices: what to do when a security problem is found.

• Lightning talks; a number of brief presentations to finish out the day.

[Your editor would like to thank the Linux Foundation for assistance with his travel to Edinburgh to attend the Kernel Summit].
