PUFFS now in DragonFly

Justin Sherrill — Wed, 08 Feb 2012 20:54:06 +0000

Nick Prokharau’s project for Google Summer of Code last year was “Port PUFFS from NetBSD/FreeBSD”. Sascha Wildner has now committed that to DragonFly. It’s experimental, so the normal caveats apply.

Summer of Code and DragonFly: who is interested?

Justin Sherrill — Wed, 08 Feb 2012 01:57:06 +0000

Google has announced that Summer of Code 2012 is in the works. I’ve announced that DragonFly will apply again. For that, I need to know who wants to be a student or a mentor, and what ideas people want to suggest.

It’s on, again! Not that there was any doubt. I need to collect potential mentor names before DragonFly can be involved, so you can guess what I’ll say next…

Got an r600-based video card?

Justin Sherrill — Fri, 21 Oct 2011 03:53:56 +0000

That would be a recent ATI card, though I don’t know exactly which model name. Samuel Greear has imported David Shao’s DRM work, originally for Summer of Code, last year. Most newer Radeons should work (?).

I got mine the other day, and here’s someone else’s.

Summer of Code and DragonFly, 2011 wrapup

Justin Sherrill — Thu, 15 Sep 2011 23:45:01 +0000

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.

BFQ scheduler writeup

Justin Sherrill — Thu, 01 Sep 2011 01:22:19 +0000

Brills Peng has written up a nice description of his scheduler work for Google Summer of Code, with details on what it does, and how to try it out. Best of all, he plans to keep working on it!

More Summer of Code results

Justin Sherrill — Tue, 30 Aug 2011 22:56:28 +0000

Another batch of code has arrived from Google Summer of Code student work. In this case, it’s code from Adam Hoka’s “Implementing a mirror target for device mapper” project, committed by Alex Hornung. I think there’s potentially more to come.

Summer of Code results already

Justin Sherrill — Sun, 28 Aug 2011 03:16:30 +0000

Google Summer of Code for 2011 just finished, and there’s already source code from it showing up in DragonFly. In this case, scheduler work, including multiple schedulers. I’ll have a more detailed report soon…

Mixing pkgsrc and alien packages

Justin Sherrill — Tue, 23 Aug 2011 23:28:30 +0000

Anton Panev is working on a Google Summer of Code project for NetBSD, adding support in pkgsrc for RPM/Debian package formats. He posted a status report recently; will this come to DragonFly via pkgsrc? I don’t know!

kqueue Summer of Code progress

Justin Sherrill — Fri, 12 Aug 2011 02:04:33 +0000

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.

Summer of Code: midterm passes

Justin Sherrill — Sat, 16 Jul 2011 02:45:10 +0000

All 6 Google Summer of Code projects for DragonFly have reached the midterm, and passed!

Vkernel checkpoint status

Justin Sherrill — Fri, 15 Jul 2011 02:58:32 +0000

Irina Pre?a has posted a nice summary of the Google Summer of Code project “Checkpointing vkernels.”

Summer of Code midterms due

Justin Sherrill — Thu, 14 Jul 2011 04:12:11 +0000

If you are a Summer of Code student or mentor, make sure you’ve filled out your midterm survey. Without it, your project fails – and they are due for everyone in roughly the next 24 hours!

Summer of Code Doc Camp

Justin Sherrill — Wed, 13 Jul 2011 01:33:39 +0000

One of the perpetual questions about Summer of Code is “Why can’t there be documentation projects?”, since most open source projects need docs as badly as code. There’s various reasons that I’m too lazy to research and type out, I’m sure, but Google is sponsoring a “Doc Camp“, in October. You don’t have to be in Summer of Code; you just have to be willing to spend the 17th through the 25th writing documentation. Google pays for room and board, and you can apply for transportation cost coverage. A classy idea, all around. Someone participate and report back!

Summer of Code halfway point

Justin Sherrill — Sun, 10 Jul 2011 01:36:07 +0000

The Google Summer of Code midterms are coming up, which generally means students get graded on a pass/fail basis for their work so far, and both mentors and students fill out surveys. What’s this mean? It means we’re halfway through six projects!

GSoC: virtio status

Justin Sherrill — Tue, 21 Jun 2011 19:37:49 +0000

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

Virtio block driver progress

Justin Sherrill — Thu, 02 Jun 2011 02:47:00 +0000

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.

Other Summer of Code: pkgsrc

Justin Sherrill — Thu, 26 May 2011 20:35:52 +0000

One of the Google Summer of Code projects that will be valuable for DragonFly even though it isn’t a DragonFly project: “Add other package formats to pkgsrc”, where pkgsrc can interpret rpm, dpkg, and FreeBSD Ports files. Anyway, the project has a Sourceforge site.

Device Mapper mirror page

Justin Sherrill — Tue, 17 May 2011 01:16:13 +0000

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.
