Fedora 18 3.8.4 rt 2.1--Is it really a Work In Progress

Hi, List and Fernando.

I have install the 3.8.4 rt 2.1 kernel on an Intel Core 2 Duo T9300 and a Geforce 9500M with absolutely no changes after a default install of Fedora 18 and RPMFusion and it is working fine. In fact, the xruns seem to be at an all time low. :-) The only issue I am seeing is that it hangs after coming back from Suspend, which the Fedora 18 default kernel didn't do.

I see a few threads on the rt kernel and Fedora 18 from a month ago, but the Planet CCRMA at Home page is saying the Fedora 18 repo is a work in progress. Are my positive results news? Is the kernel considered stable now? Is there anything that you would like tested, Fernando?

Sean

rt kernel problems

Hi folks,
Again I have to call out for some advice.

Here is what I've done:
- Installed fresh from f18 xfce live dvd (simple partitioning with ext4)
- Installed repos for ccrma and rpmfusion
- updated everything except kernel (which is now 3.6.10)
(when I tried that in one go it didn't work at all. I started fresh again and updated in pieces; first everything except kernel and xorg, then xorg).
- removed pulsaudio
- added a /etc/modprobe.d/local.conf to fix the ordering of sound devices
- used realTimeConfigQuickScan and follow advice
- run alsamixer to set the volumes
- otherwise I think I kept everything default

With this system, I can start (in order) qjackctl, jackd, qsynth and rosegarden.
I can play some simple stored music. With a processor load of 5% (according to qjackctl) I can get a latency around 10 ms without problems with xrun (just).

Not impressed. I would like to run more stuff with less latency, so I try to install the rt kernel (3.8.4) and rtirq.

This configuration starts, but it's completely useless. I start qjackctl and jackd and it looks ok. I start qsynth and try to start rosegarden. The latter never starts and the machine start to behave very strange in many ways. Windows can be moved but the app inside is not responding. Windows turning white. When i try commands in the terminal some can work but other say "Input/output error" or "read-only file system". Only way to restart is power-off the hard way.

I have started again with the stock 3.6.10 kernel and the machine is working again, but without the performance I would like to see.

Anyone have any advice?

/Bengt

FC18 rt kernels

For a couple of years I left the Fedora rt kernels alone because my wifi
failed. That got fixed sometime, so I'm using the current one for now.

fedora 18: new 3.8.4-rt2 kernel

Hi all,

I just released a new (very new!) rt patched kernel for Fedora 18, this 
one is based on the latest (202) Koji build plus 3.8.4-rt2. It seems to 
be performing well in limited tests here.

If you are happy with the current 3.6 rt kernel don't upgrade, this 3.8 
release is very new and maybe there are bugs lurking there. I'll track 
the 3.8.x rty series and release packages as new versions become available.

Enjoy!

Does this help?

sudo systemctl enable cpupower.service
and
sudo systemctl start cpupower.service

and edit /etc/sysconfig/cpupower

Unable to set cpu governors

Hello,
With fedora 17, I was able to change my cpu frequency scaling governors 
from ondemand to performance as needed.  Now when I run cpupower 
frequency-info, I'm informed that I have no frequency drivers or that 
they are not active.  When I look here: 
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor, the cpufrq is no 
longer there nor are it's components.
Any ideas or suggestions would be appreciated.

Hi Day,
Sorry to hear you are having problems, and of the worst kind (ie: system 
not booting...).

It is a weird problem that I have not seen in the two systems in which I 
have tried fc18 so far - anyone in the list with a similar experience? I 
presume you see the entries for the kernels in the grub menu, right? Do 
you see anything at all? What entries do you see? Any error messages? If 
you can edit the kernel boot line in grub, remove the "rhgb quiet" part 
so that you see all messages that are printed by the kernel as it boots, 
maybe there will be some clue there.

An option would be to boot into rescue mode (list: does that even exist 
in the new installer??) and try to redo the grub configuration once you 
chroot into the / partition.

Request for Chris Carlson's Borderlands in PlanetCCRMA

Borderlands is a granular synthesis program that does most of the
things I've been trying to accomplish for some time.  The program was
created by Chris Carlson, a CCRMA graduate, and the source code is
available under GPL.  The website for Borderlands says that it
compiles on Linux (dated last year), but I was unable to compile it.
And while Chris says he would help solve compile issues, I don't
really know what questions to ask.

This app is so cool, it would really be great to be available as a
binary, could someone at PlanetCCRMA or Fedora compile Borderlands and
put it in the repository?

     https://ccrma.stanford.edu/~carlsonc/256a/Borderlands/

This project makes me wonder, how many other cool projects are hidden in CCRMA?

landing on the Fedora 18 planet

Hi all,
I have just released a bunch of packages for Fedora 18.

The rt kernel is based on 3.6.11 plus rt25, seems to work fine on a 
couple of systems I tested.

As for the rest, the usual suspects that have not yet migrated to Fedora 
are there, including SuperCollider (3.6.2 with the new scide interface), 
pd-extended (same release as before), ChucK / miniAudicle, the 
CM/CLM/CMN/snd lisp/scheme world of tools and more.

Missing at this point (that I know of): the old legacy cm, 
cheesetracker, fweelin, tapiir, timemachine, yass, ladspa-nova-plugins 
and a few more. Not a lot as most of the cool stuff is already in Fedora!

Enjoy!
