Mention that QEMU-run programs sometimes segfault. If anyone figures out exactly why this happens, replacing this change with an explanation would be helpful. |

Upstream (NixOS) supported devices
NixOS has no official support for riscv64-linux architecture on the nixpkgs-unstable and stable channel.

Special Devices
It is possible to emulate a RISC-V platform with QEMU. Programs may occasionally crash on QEMU with a segmentation fault despite working on native RISC-V hardware.[1][2]

Installation
Getting the installer
SD card images (SBCs and similar platforms)
For riscv64
it is possible to download images from the community.
Build or download the image.
If the image has the extension .zst
, it will need to be decompressed before writing to installation device. Use nix-shell -p zstd --run "unzstd <img-name>.img.zst"
to decompress the image.
Binary cache
NixOS Support
All RISC-V platforms are experimental for the time being.
There is a dedicated room for the upstream effort on Matrix, matrix:r/riscv:nixos.org.
Awaiting upstream RISC-V support
- LuaJIT
- OpenJDK
- GHC
- Main issue
- NCG
- LLVM backend
- Binary tarballs (needed for bootstrap)
- RISC-V Label
- Valgrind
