openSUSE:RISC-V

Jump to: navigation, search

RISC-V is the free and open RISC instruction set architecture developed by the RISC-V Foundation.

Testing openSUSE images

The port is still under heavy development and considered an early preview.

On real hardware

There is support for the SiFive HiFive Unleashed board.

Using an emulator

The provided images can be used on normal PCs on a regular Tumbleweed installation, using either the qemu userspace CPU emulation, or the qemu system emulation.

QEMU user-space emulation

http://download.opensuse.org/ports/riscv/tumbleweed/images/openSUSE-Tumbleweed-RISC-V-JeOS.riscv64-rootfs.riscv64.tar.xz

Install qemu and systemd-machined:

 # zypper in qemu-linux-user systemd-container

Register qemu as handler for RISC-V binaries:

 # qemu-binfmt-conf.sh --credential yes

Prepare systemd-nspawn to not use private networking (see man 5 systemd.nspawn):

 # mkdir /etc/systemd/nspawn
 # cat > /etc/systemd/nspawn/riscv.nspawn << EOF
 [Network]
 Private=off
 [Exec]
 PrivateUsers=off
 EOF

Download a RISC-V container and register in machined:

 # machinectl pull-tar --verify=no \
   http://download.opensuse.org/ports/riscv/tumbleweed/images/openSUSE-Tumbleweed-RISC-V-JeOS.riscv64-rootfs.riscv64.tar.xz \
   riscv

Boot the container:

 # machinectl start riscv

Get a shell:

 # machinectl shell riscv

Have a lot of fun...
