Flash works too!

Justin Sherrill — Sun, 28 Mar 2010 17:17:21 +0000

Thanks to work from Samuel J. Greear and Alex Hornung:

Install Firefox (natively)
libflashsupport and adobe-flash-plugin
mount linprocfs
null mount devfs within the linux system

There’s occasional video and audio sync problems, but Johannes Hofmann has already found a fix.

Vinum root mounts possible again

Justin Sherrill — Tue, 16 Mar 2010 00:15:25 +0000

As if Alex Horning wasn’t busy enough with his Linuxulator update, he’s also made it possible to have a vinum root volume in conjunction with using devfs.

The split becomes noticeable

Justin Sherrill — Wed, 23 Sep 2009 00:20:56 +0000

This Internetnews.com article makes a good point: DragonFly has thrived since splitting from FreeBSD 5+ years ago, and the difference between the systems is more apparent now, with the introduction of DevFS and Hammer.

Unix98 ptys and devfs

Justin Sherrill — Fri, 04 Sep 2009 01:09:57 +0000

Alex Hornung has posted a summary of what Unix98 pty devices are, and how they are supported under DevFS. If something screwy happens, there’s even a debug option to turn on.

DevFS gets rules

Justin Sherrill — Wed, 26 Aug 2009 01:05:49 +0000

It’s now possible to set up rules for your dynamic device file system. If this intrigues you, and it should, there’s more details about the rules within the devfsctl(8) man page.

Vinum and devfs play together nicely

Justin Sherrill — Sun, 16 Aug 2009 20:58:25 +0000

Vinum’s been changed to work with devfs, with the advantage that drive labels instead of device paths can now be used. There’s some caveats – read the message for details.

Welcome new commiter: Alex Hornung

Justin Sherrill — Wed, 12 Aug 2009 16:16:35 +0000

I totally missed this, but Sascha Wildner reminded me: Alex Hornung now has commit access to DragonFly, due to all the devfs work he’s done.

DevFS cleanup, iSCSI start

Justin Sherrill — Tue, 11 Aug 2009 18:53:36 +0000

Matthew Dillon provided a summary of the state of the dynamic device filesystem work, plus a note about the preliminary iSCSI work. He also brings up the notion that iSCSI would eventally allow booting off a drive no matter where it’s physically connected.

DevFS and vinum do not get along

Justin Sherrill — Thu, 06 Aug 2009 15:49:17 +0000

DevFS breaks vinum. Will it be fixed? Yes, hopefully very soon.

DevFS arrives

Justin Sherrill — Tue, 04 Aug 2009 14:42:07 +0000

DevFS has been added. There’s some issues, each with a workaround. Please test, as it’s certain that a major change like this will cause new problems around video and sound. Once those are fixed, however, device management will be a lot easier.

DevFS this weekend

Justin Sherrill — Thu, 30 Jul 2009 20:32:33 +0000

The DevFS Summer of Code project is going into DragonFly this weekend; be ready for surprises if you update. It’s not complete yet; there’s a few more weeks for Summer of Code, but there’s other work that this code will enable.

Suggestions for devfs

Justin Sherrill — Tue, 14 Jul 2009 20:28:23 +0000

Alex Hornung is looking for suggestions on the userland tool(s) for his devfs project. This is a Google Summer of Code project, and I’m a bit late posting this, so hurry if you want to get your two cents in.

GSoC 2009: so far for devfs and AMD64

Justin Sherrill — Sat, 06 Jun 2009 01:19:40 +0000

Alex Hornung posted a summary of how his work on devfs is going, and Jordan Gordeev posted a summary of how much AMD64 is functional.

If you want to try either one (warning: many parts still broken!), use a vkernel for the devfs so a physical system doesn’t get broken. There’s build instructions for pulling together AMD64 DragonFly.

Update: manual instructions for AMD64, too.

devfs details

Justin Sherrill — Mon, 01 Jun 2009 02:30:38 +0000

While asking some questions, Alex Hornung let drop some of the details of his Summer of Code devfs project. Sounds like he’s making good progress.

DevFS details

Justin Sherrill — Fri, 15 May 2009 01:49:56 +0000

Alex Hornung posted a nice summary of his DevFS project for DragonFly Google’s Summer of Code – Matthew Dillon has a followup, too.

Are you a Summer of Code student for DragonFly? Don’t forget to post a summary of your project to kernel@ before the start. Yes, I know there’s exams.

Extra work for those who want it

Justin Sherrill — Thu, 26 Jul 2007 00:43:20 +0000

If you wanted to tackle something difficult, Simon ‘corecode’ Schubert has suggestions around multiprocessor development and also what is essentially a devfs.Â (Follow the threads for more information.)

devfs quickly

Justin Sherrill — Sat, 06 May 2006 03:26:26 +0000

Anyone want to write a new devfs? (That’s device file system, if you haven’t seen the term before.) A discussion about tracking disks and their appropriate mount points ended with Matthew Dillon noting that at this point, the DragonFly system is cleaned up enough that this would be an approachable task for someone with experience.

Adding device, description

Justin Sherrill — Tue, 05 Oct 2004 22:07:23 +0000

In a recent post to kernel about adding devices, Matthew Dillon describes how and why device adding on DragonFly deviated from FreeBSD-4, and how it could (eventually) lead to a different sort of devfs.

udev links

Justin Sherrill — Mon, 19 Apr 2004 20:00:36 +0000

‘esmith’ asked about udev/hotplug in contrast to FreeBSD-5′s devfs, listing these links for more info.
