+===================
+Testing BPF on s390
+===================
+
+1. Introduction
+***************
+
+IBM Z are mainframe computers, which are descendants of IBM System/360 from
+year 1964. They are supported by the Linux kernel under the name "s390". This
+document describes how to test BPF in an s390 QEMU guest.
+
+2. One-time setup
+*****************
+
+The following is required to build and run the test suite:
+
+  * s390 GCC
+  * s390 development headers and libraries
+  * Clang with BPF support
+  * QEMU with s390 support
+  * Disk image with s390 rootfs
+
+Debian supports installing compiler and libraries for s390 out of the box.
+Users of other distros may use debootstrap in order to set up a Debian chroot::
+
+  sudo debootstrap \
+    --variant=minbase \
+    --include=sudo \
+    testing \
+    ./s390-toolchain
+  sudo mount --rbind /dev ./s390-toolchain/dev
+  sudo mount --rbind /proc ./s390-toolchain/proc
+  sudo mount --rbind /sys ./s390-toolchain/sys
+  sudo chroot ./s390-toolchain
+
+Once on Debian, the build prerequisites can be installed as follows::
+
+  sudo dpkg --add-architecture s390x
+  sudo apt-get update
+  sudo apt-get install \
+    bc \
+    bison \
+    cmake \
+    debootstrap \
+    dwarves \
+    flex \
+    g++ \
+    gcc \
+    g++-s390x-linux-gnu \
+    gcc-s390x-linux-gnu \
+    gdb-multiarch \
+    git \
+    make \
+    python3 \
+    qemu-system-misc \
+    qemu-utils \
+    rsync \
+    libcap-dev:s390x \
+    libelf-dev:s390x \
+    libncurses-dev
+
+Latest Clang targeting BPF can be installed as follows::
+
+  git clone https://github.com/llvm/llvm-project.git
+  ln -s ../../clang llvm-project/llvm/tools/
+  mkdir llvm-project-build
+  cd llvm-project-build
+  cmake \
+    -DLLVM_TARGETS_TO_BUILD=BPF \
+    -DCMAKE_BUILD_TYPE=Release \
+    -DCMAKE_INSTALL_PREFIX=/opt/clang-bpf \
+    ../llvm-project/llvm
+  make
+  sudo make install
+  export PATH=/opt/clang-bpf/bin:$PATH
+
+The disk image can be prepared using a loopback mount and debootstrap::
+
+  qemu-img create -f raw ./s390.img 1G
+  sudo losetup -f ./s390.img
+  sudo mkfs.ext4 /dev/loopX
+  mkdir ./s390.rootfs
+  sudo mount /dev/loopX ./s390.rootfs
+  sudo debootstrap \
+    --foreign \
+    --arch=s390x \
+    --variant=minbase \
+    --include=" \
+      iproute2, \
+      iputils-ping, \
+      isc-dhcp-client, \
+      kmod, \
+      libcap2, \
+      libelf1, \
+      netcat, \
+      procps" \
+    testing \
+    ./s390.rootfs
+  sudo umount ./s390.rootfs
+  sudo losetup -d /dev/loopX
+
+3. Compilation
+**************
+
+In addition to the usual Kconfig options required to run the BPF test suite, it
+is also helpful to select::
+
+  CONFIG_NET_9P=y
+  CONFIG_9P_FS=y
+  CONFIG_NET_9P_VIRTIO=y
+  CONFIG_VIRTIO_PCI=y
+
+as that would enable a very easy way to share files with the s390 virtual
+machine.
+
+Compiling kernel, modules and testsuite, as well as preparing gdb scripts to
+simplify debugging, can be done using the following commands::
+
+  make ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- menuconfig
+  make ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- bzImage modules scripts_gdb
+  make ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- \
+    -C tools/testing/selftests \
+    TARGETS=bpf \
+    INSTALL_PATH=$PWD/tools/testing/selftests/kselftest_install \
+    install
+
+4. Running the test suite
+*************************
+
+The virtual machine can be started as follows::
+
+  qemu-system-s390x \
+    -cpu max,zpci=on \
+    -smp 2 \
+    -m 4G \
+    -kernel linux/arch/s390/boot/compressed/vmlinux \
+    -drive file=./s390.img,if=virtio,format=raw \
+    -nographic \
+    -append 'root=/dev/vda rw console=ttyS1' \
+    -virtfs local,path=./linux,security_model=none,mount_tag=linux \
+    -object rng-random,filename=/dev/urandom,id=rng0 \
+    -device virtio-rng-ccw,rng=rng0 \
+    -netdev user,id=net0 \
+    -device virtio-net-ccw,netdev=net0
+
+When using this on a real IBM Z, ``-enable-kvm`` may be added for better
+performance. When starting the virtual machine for the first time, disk image
+setup must be finalized using the following command::
+
+  /debootstrap/debootstrap --second-stage
+
+Directory with the code built on the host as well as ``/proc`` and ``/sys``
+need to be mounted as follows::
+
+  mkdir -p /linux
+  mount -t 9p linux /linux
+  mount -t proc proc /proc
+  mount -t sysfs sys /sys
+
+After that, the test suite can be run using the following commands::
+
+  cd /linux/tools/testing/selftests/kselftest_install
+  ./run_kselftest.sh
+
+As usual, tests can be also run individually::
+
+  cd /linux/tools/testing/selftests/bpf
+  ./test_verifier
+
+5. Debugging
+************
+
+It is possible to debug the s390 kernel using QEMU GDB stub, which is activated
+by passing ``-s`` to QEMU.
+
+It is preferable to turn KASLR off, so that gdb would know where to find the
+kernel image in memory, by building the kernel with::
+
+  RANDOMIZE_BASE=n
+
+GDB can then be attached using the following command::
+
+  gdb-multiarch -ex 'target remote localhost:1234' ./vmlinux
+
+6. Network
+**********
+
+In case one needs to use the network in the virtual machine in order to e.g.
+install additional packages, it can be configured using::
+
+  dhclient eth0
