it isn't too hard to build a rt_preempt kernel. I have done it a few times now with the help of peters instructions..
cd ~ sudo apt-get update sudo apt-get install build-essential bin86 kernel-package libqt4-dev #libncurses5-dev pkg-config mkdir rtlinux cd rtlinux wget ftp://ftp.kernel.org/pub/linux/kernel/v4.x/linux-4.4.7.tar.xz wget https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4.7-rt16.patch.gz tar -xpf linux-4.4.7.tar.xz gunzip patch-4.4.7-rt16.patch.gz cp patch-4.4.7-rt16.patch linux-4.4.7 cd linux-4.4.7 cat patch-4.4.7-rt16.patch | patch -p1 make xconfig make -j4 sudo make modules_install sudo make install This was 4.4.7 - I think I am running a bit newer now... (change the links accordingly) 4.4.9-rt17 #1 SMP PREEMPT RT Sun May 15 20:22:00 CDT 2016 x86_64 GNU/Linux Also - make sure when you run the make xconfig you select 'Fully Preemptable Kernel (RT)' sam On 06/17/2016 08:38 AM, Todd Zuercher wrote: > Well that kind of sucks.
