Category: Google Summer of Code

DragonFly had another good year with Google’s Summer of Code program.  We had 6 slots, and 5 passed projects. (Irinia, if you’re reading this – where did you go?)  This is our 4th year participating in Summer of Code, with I think the highest number of passed projects to date.

Here’s all the finished projects, with links to the original descriptions:

• Bring kernel event notification in DragonFly BSD to its logical conclusion – Samuel Greear
• Implementing a mirror target for device mapper – Adam Hoka
• Improve dsched interfaces and implement BFQ disk scheduling policy – Brills Peng
• Port PUFFS from NetBSD/FreeBSD – Nick Prokharau
• Porting Virtio Drivers from NetBSD to DragonFly BSD to speed up DragonFly BSD as a KVM guest – Stephanie Ouillon

Thanks is also due to the mentors and other that helped out, via IRC and email: Aggelos Economopoulos, Alex Hornung, Joe Talbott, Matthias Schmidt, Michael Neumann, Nathaniel Filardo, Pratyush Kshirsagar, Sascha Wildner, Thomas Nikolajsen, and Venkatesh Srinivas

You can also check the Digest’s “Google Summer of Code” category for progress reports made as the summer went on.  The source code from the projects is available at the DragonFly/SOC 2011 Google Project Page.  In even better news, 2 of the projects have already been partially committed to DragonFly – Brills Peng’s  scheduler work, and Adam Hoka’s device mapper mirror project.

Samuel Greear posted a progress report on his kqueue Summer of Code project.  There’s code available now to try it out.  It sounds grand, though I can’t identify what effects it will have for the end user.

There’s an update on Stéphanie Ouillon’s Google Summer of Code project, working on the virtio block device driver.

Stéphanie Ouillon has posted extensive details on the Virtio Google Summer of Code project; a few questions are included for anyone who wants to jump in and offer feedback.

Adam Hoka, a student in Google Summer of Code for DragonFly, has created a wiki page for his device mapper mirroring project.  Not a lot there, but I’m happy to see the reference.

And here’s one last writeup/introduction for Google Summer of Code projects on DragonFly: kevent part 2.  (Apparently school exams prevented this from being written sooner.)

Kedar Soparkar applied for Google Summer of Code with DragonFly, but didn’t make the cut with the very few slots we have.  So, he’s going to work on his i386 ABI implementation anyway.   More student work is always wonderful news.

Two more of the DragonFly and Google Summer of Code projects: Irina Presa’s checkpointing vkernels, where you can save a running virtual kernel and start it again later, and Nick Prokharau’s port of PUFFS.

(Anyone know the HTML character code for ‘s’ with an inverted grave mark so I can spell Irina’s name correctly?)

Yay acronyms! Brills Peng was accepted for the Summer of Code project “Improve dsched interfaces and implement BFQ disk scheduling policy” – and now there’s a nice writeup describing what’s planned. Also, Stéphanie Ouillon did the same thing for the virtio drivers project.  Adam Hoka also joined in with a summary for his LVM mirror project.  Please keep this up, students.
