+# `s390x-unknown-linux-gnu`
+
+**Tier: 2 (with Host Tools)**
+
+IBM z/Architecture (s390x) targets (including IBM Z and LinuxONE) running Linux.
+
+## Target maintainers
+
+- Ulrich Weigand, <ulrich.weigand@de.ibm.com>, [@uweigand](https://github.com/uweigand)
+- Josh Stone, <jistone@redhat.com>, [@cuviper](https://github.com/cuviper)
+
+## Requirements
+
+This target requires:
+
+* Linux Kernel version 3.2 or later
+* glibc 2.17 or later
+
+Code generated by the target uses the z/Architecture ISA assuming a minimum
+architecture level of z10 (Eighth Edition of the z/Architecture Principles
+of Operation), and is compliant with the s390x ELF ABI.
+
+Reference material:
+
+* [z/Architecture Principles of Operation][s390x-isa]
+* [z/Architecture ELF Application Binary Interface][s390x-abi]
+
+[s390x-isa]: https://publibfp.dhe.ibm.com/epubs/pdf/a227832d.pdf
+[s390x-abi]: https://github.com/IBM/s390x-abi
+
+## Building the target
+
+This target is distributed through `rustup`, and otherwise requires no
+special configuration.
+
+If you need to build your own Rust for some reason though, the target can be
+enabled in `config.toml`. For example:
+
+```toml
+[build]
+target = ["s390x-unknown-linux-gnu"]
+```
+
+## Building Rust programs
+
+On a s390x Linux host, the `s390x-unknown-linux-gnu` target should be
+automatically installed and used by default.
+
+On a non-s390x host, add the target:
+
+```bash
+rustup target add s390x-unknown-linux-gnu
+```
+
+Then cross compile crates with:
+
+```bash
+cargo build --target s390x-unknown-linux-gnu
+```
+
+## Testing
+
+There are no special requirements for testing and running the target.
+For testing cross builds on the host, please refer to the "Cross-compilation
+toolchains and C code" section below.
+
+## Cross-compilation toolchains and C code
+
+Rust code built using the target is compatible with C code compiled with
+GCC or Clang using the `s390x-unknown-linux-gnu` target triple (via either
+native or cross-compilation).
+
+On Ubuntu, a s390x cross-toolchain can be installed with:
+
+```bash
+apt install gcc-s390x-linux-gnu g++-s390x-linux-gnu libc6-dev-s390x-cross
+```
+
+Depending on your system, you may need to configure the target to use the GNU
+GCC linker. To use it, add the following to your `.cargo/config.toml`:
+
+```toml
+[target.s390x-unknown-linux-gnu]
+linker = "s390x-linux-gnu-gcc"
+```
+
+If your `s390x-linux-gnu-*` toolchain is not in your `PATH` you may need to
+configure additional settings:
+
+```toml
+[target.s390x-unknown-linux-gnu]
+# Adjust the paths to point at your toolchain
+cc = "/TOOLCHAIN_PATH/bin/s390x-linux-gnu-gcc"
+cxx = "/TOOLCHAIN_PATH/bin/s390x-linux-gnu-g++"
+ar = "/TOOLCHAIN_PATH/bin/s390x-linux-gnu-ar"
+ranlib = "/TOOLCHAIN_PATH/bin/s390x-linux-gnu-ranlib"
+linker = "/TOOLCHAIN_PATH/bin/s390x-linux-gnu-gcc"
+```
+
+To test cross compiled binaries on a non-s390x host, you can use
+[`qemu`](https://www.qemu.org/docs/master/system/target-s390x.html).
+On Ubuntu, a s390x emulator can be obtained with:
+
+```bash
+apt install qemu-system-s390x
+```
+
+Then, in `.cargo/config.toml` set the `runner`:
+
+```toml
+[target.s390x-unknown-linux-gnu]
+runner = "qemu-s390x-static -L /usr/s390x-linux-gnu"
+```

+
+## Target maintainers
+
+- Ulrich Weigand, <ulrich.weigand@de.ibm.com>, [@uweigand](https://github.com/uweigand)
+
+## Requirements
+
+This target requires:

+
+## Building the target
+
+Because it is Tier 3, Rust does not yet ship pre-compiled artifacts for this
+target.
+
+Therefore, you can build Rust with support for the target by adding it to the
+target list in `config.toml`, a sample configuration is shown below.
+
+```toml
+[build]
+target = ["s390x-unknown-linux-musl"]
+```
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for this target. To compile for
+this target, you will first need to build Rust with the target enabled (see
+"Building the target" above).
+
+## Testing
+
+There are no special requirements for testing and running the target.
+For testing cross builds on the host, please refer to the "Cross-compilation
+toolchains and C code" section below.
+
