Re: [LAU] RT kernel

Hi, use export CONCURRENCY_LEVEL=[...] if you want to build with several jobs. You could use fake root, if you dislike to build with root privileges. However, this are the commands you need to run, when building with root privileges. Replace [...] with what's missing, use a browser to visit those sites. The rt patch must exactly fit to the kernel version. wget https://www.kernel.org/pub/linux/kernel/[...].tar.gz wget https://www.kernel.org/pub/linux/kernel/projects/rt/[...].patch.gz sudo -i Extract the kernel tar zxf linux-[...] Rename the extracted directory to the rt name mv linux-[...] linux-[...]-rt[...] Change into the extracted directory and patch the kernel. cd linux-[...]-rt[...] gzip -dc ../patch-[...].patch.gz | patch -p1 Copy the config of e.g. an Arch rt kernel or the config of the non-rt you are running to the directory https://aur.archlinux.org/cgit/aur.git/snapshot/linux-rt.tar.gz https://aur.archlinux.org/cgit/aur.git/snapshot/linux-rt-lts.tar.gz respectively cp /boot/config-$(uname -r) config Configure the kernel make oldconfig Build the kernel make-kpkg clean make-kpkg --initrd kernel-image kernel-headers Building the kernel most likely fails two or three times, you most likely need to disable a few configurations. To do this read the error messages and use make menuconfig it has got a search option, so you easily could find what to disable, OTOH sometimes it's faster to use an editor and directly disable an option. Repeat running make oldconfig make-kpkg clean make-kpkg --initrd kernel-image kernel-headers Use apt install or dpkg -i to install the packages. This is the Debian way to build a kernel, that works without failure for Ubuntu, too. Actually there's an Ubuntu way that is a little bit different. This is how I successfully build rt patched kernels for Ubuntu countless times. If you should be inexperienced in configuring a kernel, 1. oldconfig's and menuconfig's help, 2. Google and 3. this list are your friends, in exactly that order ;). Regards, Ralf
