Following steps describes the build of an realtime kernel (preemption patch) for a debian based distribution for embedded systems, as example we compile the kernel for an apollo lake (x86_64) and a beagle bone (armhf) board.

x86_64 Version:

This workflow uses also Debian 8.6 Jessie as host/development operating system.

Install following packages:

$ sudo apt-get install kernel-package build-essential linux-source fakeroot libncurses5-dev libssl-dev

get the linux kernel using wget or git:

$ wget 
$ tar -xJf linux-4.4.39.tar.xz 
$ git clone git://
$ cd linux-stable
$ git checkout linux-4.4.y 
$ cd ..

Preemptive Patch:

$ wget
$ xz -d patch-4.4.39-rt50.patch.xz
$ cd linux-4.4.39  or $ cd linux-stable
$ cat ../patch-4.4.39-rt50.patch | patch -p1

configure the kernel:

$ make menuconfig ARCH=x86_64

compile the kernel to get a debian package and install it:

$ fakeroot make-kpkg --initrd --revision=1.0.mahdevel kernel_image
$ cd ..
$ dpkg -i linux-image-4.4.39-rt50_1.0.mahdevel_amd64.deb

or compile it without make-kpkg:

make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=mhaag


compile custom realtime kernel for Debian 8.6 (Jessie)
