[...] redFrick uses SuperCollider, which is a language that’s fairly popular with live coders. Another SuperCollider live coder is Marije Baalman. She’s one of the core developers of SuperCollider. We watched a video of her live coding on a Greyhound bus, which you can download from here. [...]

Comment on 2.6.29 realtime kernel for Debian by Bas

Erm, that should be revision with two dashes in front of it.

Somehow all my double dashes have turned into single dashes, sorry for the confusion

Just to let you know: if you’re using Debian’s unstable or testing branch, one of the commands used in this page has changed :

time fakeroot make-kpkg –initrd -rev mz1 kernel_image kernel_headers

has become:
time fakeroot make-kpkg –initrd –revision mz1 kernel_image kernel_headers

i.e. make-kpkg’s -rev option is now –revision

So if you get an error message like:
Unknown option: r
Unknown option: e
Unknown option: v
then use the –revision instead of -rev

Thanks for this.. I just got the RT patch running on my x86_64 Intel Atom 330 board with 2.6.31.4 release. I did a few things differently..

———————————————————————
Your new kernel & headers now live in ../kernel Use dpkg -i to install (as root).
dpkg -i ../linux-headers-*.deb ../linux-image-*.deb

ME> I executed this from /usr/src rather than /usr/src/linux-2.6.31.4 which
ME> may or may not explain below..

So good so far… but the kernel didn’t boot yet…
and the initrd file was missing

ME> Mine did.. initrd file was created and installed.

So with the initramfs-tools from the debian repository,
I did (as root)
mkinitramfs -o /boot/initrd.img-2.6.29-rt16 2.6.29-rt16
which created the initrd image.

ME> I didn’t have to do this step

Thanks!!

Hello thought I’d drop in here since I’ve just spent a few days trying to get the ‘ultimate’ stable audio system going on a Thinkpad T400/ RME multiface expresscard combination… in conclusion, I’ve ended up running a stock, non-realtime kernel in stock Ubuntu 8.10 with no frill whatsoever. I tried all sorts – ubuntustudio 8.04.1, debian lenny + self built 2.6.29 rt kernel, 64stiudio, ubu 9.04. I have found that this is the most stable option for me. The problem was that I wanted to have the ATI card running quietly, which it did not do with the open source drivers ait/ radeonhd (fan on all the time), i wanted no xruns and I wanted the wifi to work. suspend to RAM was a bonus. Apart from the mystical 2.6.24-rt kernel in Ubu 8.04, no realtime kernel that I tried would work with the ATI proprietary drivers. I didn’t use 8.04 since the wifi did not work and it ended up being really unstable with the RME.

With the stock 8.10 system, jockey-installed ati drivers I just run jack as root – sudo jackd -R -d alsa -d hw:1 and I can happily run my RME multiface at ~21ms latency with no xruns with supercollider and a heavy CPU load, which is find for me. I know that’s not 2ms… but at least it works, Don’t know why, but those realtime kernels make me feel like I’m somehow vilolating my system…

another EPIC fail of Debian’s was the tinkering with “kernel-package” as to NOT include an initrd image even when *I SPECIFY* in make-kpkg that I want one! How counter-intuitive can you get? At least Ubuntu hasn’t gone this route yet and still uses a SANE kernel-package that actually *GASP* creates and installs an init image when I tell it to. I love Debian to death, but come on!

I really just posted this, so I am still testing things out, as it is not yet performing as well as I want.
I started an email thread on the Linux-Audio-Users list on this too.

The audio apps I am using are mainly jack and SuperCollider, with the occasional wave editor at times (mhwaveedit currently).

My main purpose to build a realtime kernel is to get rid of xruns I am getting with the stock kernels, which are quite annoying during performances with about 500 or more people hearing them.
