There was not much to tell in the last months. I was busy with moving and the pregnancy of my wife (ok, she was more busy with this than I was…).

So the recent updates are, that I took some time to commit some of my patches to SVN. Most of them are in my SVN [...]

Today I fixed 3 linux ports (converting to the “new” world order) to not use RPM directly (the right thing is to use rpm2cpio, and bsd.linux-rpm.mk provides some nice stuff to handle this).

In the last week I fixed some stuff in the linuxulator-MFC patch. It should now compile on amd64 and i386 without problems (at [...]

I had a look at some USB PRs and wrote a list of those with patches to Warner (as he is working on USB stuff currently). I also categorized them (easy, not easy, maybe already fixed, ...). The easy ones he handled already, for the rest I don’t know his current plans.

Regarding linuxulator stuff I’m [...]

ZFS is there. Great! Thanks Pawel!

Now I wait a little bit until the first bugs are ironed out, and then I move all my stuff to it. The nice part: when you have 2 machines and everything you use is jailed, you just can do this without an “interruption of service” (or at least only [...]

Yeah! Finally I got time to finish my work to put a desktop environment (in this case GNOME) into a jail. At least I have a proof of concept (I write this with firefox running in my “deskjail”). No, I don’t do this for additional security (there’s more security than in a non-jailed setup, but [...]

The linuxulator is synced on amd64 with i386 (since a while). This means TLS is working now and we have the same (a little bit buggy) futexes.

Roman is slowly working on the *at() commands. He also applied for the GSoC this year again. Kib is willing to mentor (in case Roman gets a free seat [...]

Today I committed the updated linux aio stuff to p4. It’s a module now, so it can be loaded as needed. I also updated the p4 diff in the wiki, so anyone can download and test it (please do it!).

Major features in the p4 diff are futexes and TLS for amd64. So if you own [...]

After the call for public testing we got some reports about LORs and a panic. This happened after an extensive parallel compiling session of linux stuff on a SMP system for several hours. Roman redid some of the locking and the fixes are in the tree. Intermediate patches already showed promising results. We’re waiting for [...]

Since my call for testing the extended linuxulator in FreeBSD-current we got not much negative responses. Ping doesn’t work on the linux side (fixed in p4), ordinary network connections (e.g. downloading some stuff) works fine. There seems to be a deadlock on SMP systems when compiling a lot of stuff in parallel (e.g. using emerge [...]

Ryan got permission to extend the work he did in the SoC as part of a class at university. He wants to push down the new mixer stuff to the driver level now. He does it in the emu10kx driver (because he has such a card) and maybe in another driver. This will allow to [...]
