$ git clone git://github.com/raspberrypi/tools.git
  • Add the bin folder to PATH:
$ PATH=rpi_kernel/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin:$PATH
  • Download kernel sources:

$ wget https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4.38-rt49.patch.gz
  • Apply the patch:
$ cd linux
KERNEL=kernel
cat ../patch-4.4.XX-rtYY.patch | patch -p1
  • Make an RPi default configuration:
$ make ARCH=arm CROSS_COMPILE=/arm-linux-gnueabihf- bcmrpi_defconfig menuconfig
  • Enabling the FULL PREEMPTIBLE KERNEL:

  • Compiling the kernel:
$ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs
  • To install kernel and modules on your Raspberry follow the official guide from: Install directly onto the SD card
