There's some instructions on our wiki[1], the tldr is: cd ~/tmp wget https://toolchains.bootlin.com/downloads/releases/toolchains/powerpc64le-power8/tarballs/powerpc64le-power8--glibc--stable-2023.11-1.tar.bz2 tar -xf powerpc64le-power8--glibc--stable-2023.11-1.tar.bz2 export CROSS_COMPILE=$PWD/powerpc64le-power8--glibc--stable-2023.11-1/bin/powerpc64le-linux- cd ~/src/linux export ARCH=powerpc make defconfig make headers make -C tools/testing/selftests/powerpc cheers 1: https://github.com/linuxppc/wiki/wiki/Building-powerpc-kernels
