[Bug 290498] Re: linux-rt restricted to one CPU
This bug appears to be solved in Karmic. As far as I can tell the current Karmic RT kernel (2.6.31-9-rt) does not have the SMP issue that Intrepid's and Jaunty's had. If I had to guess, I would say this is because the kernel version matches the upstream RT patch version this time around, which hadn't happened since Hardy. In my opinion, the RT patch is highly non-trivial to port across kernel versions, and the Ubuntu linux-rt maintainers should stick to shipping the latest kernel version for which an RT patch was published, even if it doesn't match that of the generic kernel, because chances are that users will lose more from the RT kernel being broken than they would gain from having a newer kernel. Or to ship both. -- linux-rt restricted to one CPU https://bugs.launchpad.net/bugs/290498 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 290498] Re: linux-rt restricted to one CPU
Realtime Dutchman's instructions for compiling a kernel are excellent. This was my first time compiling a kernel and I was able to do so with no problems compiling or installing. I have an AMD Athlon64 X2 5600+ (i.e. dual-core). When I compiled the exact generic kernel and patch recommended by Realtime Dutchman (linux-source-2.6.29_2.6.29-02062905_all.deb and patch-2.6.29.5-rt21.bz2), it seems to have resolved everything. No system issues, no xruns on jackd and the load on the CPUs looks normal: Cpu0 : 0.3%us, 0.3%sy, 0.0%ni, 99.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 1.0%us, 0.7%sy, 0.0%ni, 98.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st NB: When I compiled and installed what I believe to be the most recent generic kernel code and rt patch as of this writing (i.e. linux- source-2.6.29_2.6.29-02062906_all.deb and patch-2.6.29.6-rt23.bz2), I experienced intermittent issues with my USB keyboard's keys getting 'sticky' (i.e. single keystroke results in multiple characters) and what looked like a video card issue when the machine booted up (just once). Not sure if this is related, but my machine has an NVidia video card (GeForce 7100 GS). -- linux-rt restricted to one CPU https://bugs.launchpad.net/bugs/290498 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 290498] Re: linux-rt restricted to one CPU
Thank you Realtime Dutchman, following your instructions I successfully compile and run a 2.6.29.6 realtime kernel under cruchbang 9.04. It works nicely with jack and vmware workstation. In theory a generic 2.6 kernel should handle HZ 100 using special config in /etc/security/limits.conf: @audio - rtprio 99 @audio -memlock unlimited and so handles jack realtime option, but I find that the 2.6.29.6 realtime kernel works much better with vmware workstation: with the generic kernel I had some hangs/sluggish in the Windows XP guest due to /etc/rtc I suppose.

Cecil, Many thanks for your help concerning the nvidia driver issue. For anyone who is interested in the kernel building tutorial please find the tutorial text below. This is the tutorial written by me and has been tested by others and is a pretty much cut and paste method. %%% %%% Kernel building tutorial for Ubuntu Studio 9.04 build 2.6.29.5-rt21-all-nvk-062109-1 Source code based on Ubuntu Studio Generic with RT patch from kernel.org. __ 1. Introduction. This tutorial describes in nine steps how to get kernel sources and how to compile, build and install a new real time kernel for Ubuntu Jaunty 9.04. The procedure as desribed below has been tested by the author but gives no guarantee for other pc hardware/software setups, but feel free to try the kernel building steps at your own risk. This tutorial desribes how to obtain, patch and compile Ubuntu Studio generic kernel. Real time patch wil be obtained from kernel.org. IMPORTANT NOTE: Before you start using the tutorial you should take notice of the following issue concerning nvidia proprietary drivers. Users who are using nvidia proprietary drivers should take care because these drivers could lead to building errors. I would like to refer to the comments made by Cecil on web page: https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/290498/ She has made the following comment: $$$ Using RTD's tutorial I was able to build 2.6.29.5-rt21 for my 9.04 system. (AMD 64 bit). I had one problem and it's doozy. It died in the very last step of the build because I had the nvidia drivers (non free). The kernel would boot and run (but a few things didn't work). It took a lot of hacking around to get rid of *all* of the nvidia artifacts so that syslog/messages/X.log didn't have errors. My advice is that if you have propriety drivers and you want to build a custom kernel, that you remove all the proprietary drivers before building the kernel. Then you can figure out how to get the proprietary drivers re-installed. Actually, my first thought would be to not build a custom kernel if you have proprietary drivers but if you do, you better know your dpkg and looking at the log files in recovery mode. $$$ 2. Installing tools: ## Become root: sudo -s ## For building the new kernel you need to install development tools first. apt-get install kernel-package ncurses-dev fakeroot bzip2 wget 3. Obtain and install generic kernel sources. ## Obtain the latest Ubuntu Studio generic kernel source for which a real-time patch is available at kernel.org: Go to web site: http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D download linux-source-2.6.29_2.6.29-02062905_all.deb (this was the kernel source available at the time of writing this tutorial) Then go to web site http://www.kernel.org/pub/linux/kernel/projects/rt/ download patch-2.6.29.5-rt21.bz2 Both files should now be in your desktop directory. ## Install generic kernel Double click the obtained linux-source-2.6.29_2.6.29-02062905_all.deb from your desktop location. The system will now install the sources. After installation the packed source file linux-source-2.6.29.tar.bz2 can be found in /usr/src. ## Store the sources in your home directory: cd /home/user(user is your own home directory) ## Create a kernel directory in /home/user mkdir kernel ## go to the kernel directory: cd kernel ## Copy source file and patch file to /home/user/kernel/ cp /home/user/desktop/patch-2.6.29.5-rt21.bz2 /home/user/kernel/patch-2.6.29.5-rt21.bz2 cp /usr/src/linux-source-2.6.29.tar.bz2 /home/user/kernel/linux-source-2.6.29.tar.bz2 ## Check if both files are really there by typing : dir 4. Unpack sources. ## unpack the kernel sources: tar -xjvf linux-source-2.6.29.tar.bz2 Tar will unpack all files and create a linux-source-2.6.29 directory in /home/user/kernel 5. Patch kernel source for real time use. ## Go to the kernel root directory: cd ~/kernel/linux-source-2.6.29 ## Patch the kernel: bzcat ../patch-2.6.29.5-rt21.bz2 |patch -p1 ## Go back to the kernel directory: cd .. 6.

Hi, Here are my experiences of using Realtime Dutchman's 25th May build for about 36 hours: Firstly, I am running with a different installation order from RTD: 1. Install 9.04 studio (all multimedia options) - reboot 2. Install all updates - reboot 3. Add workaround for clash involving snd-hda-intel driver and my system (see below) - reboot 4. Install headers 5. Install image - reboot. 6. Enable memlock 50% nice -99 via @ - System - Administration - Ubuntu Studio Controls - Reboot My acpi works infinitely better with kernel than it did without! I have not dared enable wireless yet in any shape or form because the iwl3945 driver seems yet again to be very broken. I will try this later. So far, my system: - Boots - Reboots - Shuts down - ~0% idle CPU - realtime Jack - captures and plays back audio (jack, audacious, audacity, ZynAddSubFx) - suspends, resumes and hibernates (caveat - some processes exit) * IT DOES THESE RELIABLY * This is 100% improvement on the stock studio realtime kernel. My snd-hda-intel needs a tweak to alsa-base.conf and the volume controls, but this is nothing to do with this realtime kernel; it's been a problem with my system at least as far back as hardy: options snd-hda-intel model=dell-m27 enable_msi=0 probe_mask=1 Unmute the capture channel in the standard volume control / alsa mixer. For those interested, without this JACKD watchdog timeouts trying to open the capture channel. My system is as follows: Dell Inspiron 9400 / E1705, 1GB memory, Core Duo 1.8GHz, Intel 945GM graphics, SigmaTel HDA, Intel 3945ABG wireless. ** Attachment added: lspci -vv output http://launchpadlibrarian.net/27297638/lspci-vv.txt -- linux-rt restricted to one CPU https://bugs.launchpad.net/bugs/290498 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 290498] Re: linux-rt restricted to one CPU
I have been testing a couple of nights and it happened everytime I had done a Jaunty update. I could pretty well be a motherboard related issue because my suspicion was pointing to the acpid tools. so what I did is : 1. install 9.04 2. install wicd wireless network tool (skip this when you don´t need it) +reboot 3. removal of acpid and dependencies +reboot 4. jaunty update + reboot 5. install of both new ubuntu based RT kernel + reboot: Files for everyone to use (at own risk) can be found at: https://www.yousendit.com/download/MnFqYURNTkw5bEJMWEE9PQ 5. changed audio settings sudo gedit /etc/security/limits.conf at the end of file: @audio - rtprio 99 @audio - memlock unlimted @audio - nice -19 And voila no problem anymore, a perfected running pc. I did a reboot almost after every installation action because I wanted to know if the sound modules were still in working condition after I had done the installs.

Vivichrist, The last couple of nights I have been trying to reproduce an Ubuntu Studio 9.04 system with our new RT kernels but I'm dealing with an inconsistent clean jaunty install. The problems I'm having is that sometimes Jaunty does not want to shutdown and after that my sound gets killed. At first I thought that it had to do with the new RT kernels but I am pretty sure that this is not the case because I also saw this problem once after I made a clean Jaunty install and a system update through update manager. What happens is that I get an --apci exiting-- problem when I try to reboot the system, followed by the fact that my sound is gone. Do you also experiencing such problems and if so what is your solution to work around this problem. Would it be better to make a clean install, then install the generic kernel and then install one of the new RT kernels we have been working on?

[Bug 290498] Re: linux-rt restricted to one CPU
Guys, I have been testing kernel 2.6.29.1-rt8 quite a bit now. This is the home made kernel Luke MacNeil had put on his web site. see download links: http://www.lukemacneil.com/linux-headers-2.6.29.1-rt8-custom_2.6.29.1-rt8-custom-10.00.Custom_i386.deb http://www.lukemacneil.com/linux-image-2.6.29.1-rt8-custom_2.6.29.1-rt8-custom-10.00.Custom_i386.deb Firstly install 9.04 from scratch and after that install both debs by double clicking the files. Ignore the two ¨hmm¨ warnings you will get during installation. Then run update-manager if you want to. Do not use wicd network tool for wireless because it gave trouble in my pc causing it not to shut down properly (acpid exiting problem). I installed the ubuntu network manager instead. I have running it on a my single core P4 and on a dual core pc (Intel E8400) and runs without crashing and audio is handled real time as it should. Jack shows me latencies far below 1 ms . Jack settings: Priority = 89 Frames/Period = 128 Sample Rate = 48000 Periods/Buffer = 3 The rest is default settings. It seems that Luke has managed to build a fast kernel without speed and instability troubles. As far as I understand he has used an old ubuntu kernel configuration to setup his kernel (Hardy? I am not sure). Het took his sources from kernel.org. see web site : http://www.mail-archive.com/ubuntu-studio-us...@lists.ubuntu.com/msg04152.html I hope someone at the Ubuntu Studio team can have a look at the jaunty kernel and compare it with Lukes just to find out what is causing an almost unworkable situation. If i have some time left I will try to duplicate Lukes work and see if I can get the same results with newer kernel versions. I will keep you posted.

[Bug 290498] Re: linux-rt restricted to one CPU
Mike, I installed the official jaunty 9.04 release and don't see any improvements concerning CPU performance. It still is very slow, asking to much time from my cpu and the strange thing is that when I install jaunty on a dual core pc (Intel cpu) it appears to be very unstable but I don't see the delays. Even during installation I had a system hang/crash which resulted in doing the installation all over again. After googling I found out that I'm not the only one having this nasty issue. Last night I gave up using the official ubuntu 2.6.28-3-rt kernel and compiled my own from the www.kernel.org site. I used info from the following web page : https://lists.ubuntu.com/archives/ubuntu-studio-users/2009-May/004757.html and the Debian tutorial how to build a kernel. It took almost three hours before the pc had ended its complie and linking actions but finally I was able to generate to installation deb. files for kernel 2.6.29.3-rt13 which is running on my pc.

@Alessio: not quite. I've installed the 2.6.28-2-rt kernel on my desktop and my laptop, which have nothing in common hardware-wise. The kernel does see the second core, but (reportedly) it's unusable. Running 'top' and pressing '1' I get: Cpu0 : 0.7%us, 0.3%sy, 0.0%ni, 99.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 4.3%us, 0.7%sy, 0.0%ni, 0.0%id, 0.0%wa, 95.0%hi, 0.0%si, 0.0%st The second core remains at 95-99% no matter what. Plus, if I try to reboot, by using the user-switch applet on my desktop or by pressing the power button on my laptop for the dialogue to show up, the computer stops responding to keyboard and mouse events (I do see my temperature and CPU monitor applets updating themselves, so the computer does not hang entirely), and the computer does not reboot.
