What Linux distribution are you using? - for example, if you are using Ubuntu, you can probably get an rt-kernel either from a PPA, or the Kxstudio repositories. Archlinux has packages available in AUR (Arch User Repository). Fedora should also have rt-kernels available through Planet CCRMA. > Can you point me into right direction on how properly configure 3.0-rt. > Is 3.0-rt considered stable? It's pretty stable over here; [ninez@ninez ~]$ uname -a Linux ninez 3.0-rt #1 SMP PREEMPT RT Sat Oct 22 11:44:07 EDT 2011 x86_64 AMD Phenom(tm) II X4 965 Processor AuthenticAMD GNU/Linux I am using the last official release, linux-rt 3.0.7-rt20. it works very well, although i had to patch the kernel to allow the proprietary Nvidia driver to build and install properly. (this isn't included in the RT patch, as it violates the GPL, and thus the patch cannot be distributed). I'm using Archlinux, and to 'point you in the right direction' as to what needs to be enabled/disabled in the kernel .config ... i will point you to the AUR for linux-rt. From there just download the tarball. after unzipping it, you will see the latest rt-patches, configs for x86 (labeled config) and x86_64 ... https://aur.archlinux.org/packages.php?ID=51360 That PKGBUILD also has links to the kernel sources, but doesn't include them in the tarball or anything. Arch's PKGBUILDs are like gentoo's ebuild's , you run the script and it downloads the sources, patches them, compiles it and installs it. (it does all the work). I myself, haven't seen any tutorials for linux-rt 3.0 , but i if someone else knows, i am sure they will pass along a link. I would be surprised though, if you couldn't find RT already built, assuming you are using one of the major distros. cheerz -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
