Project listing

The RISC-V project is an effort to bring first-class RISC-V CPU architecture support in Gentoo.

Status

Experimental riscv64 stages are available, and a minimum set of packages in the Gentoo repository is keyworded. At the moment we have the following stages:

  • riscv64gc / lp64d, openrc
  • riscv64gc / lp64d, systemd
  • riscv64imac / lp64, openrc
  • riscv64imac / lp64, systemd


qemu-riscv can run riscv64 binaries just fine. This way one can also test in an emulated chroot.

What needs to be done

Things to happen yet:

  • Integrate the stage3 generation into the weekly autobuilds.
  • Provide a bootable image.
  • Get riscv32 running somehow.

Keywording policy

  • ARCH=riscv is the assigned keyword.
  • No stable riscv keywords are planned for the moment.
  • For packages without obvious hardware aspect, qemu-user or qemu-system testing is sufficient for keywording ~riscv
  • Packages with hardware aspect (bootloader, drivers, ...) have to be tested on real hardware.
  • Multilib packages should get tested for both lp64d and lp64 ABI, for others lp64d is sufficient
  • When we get to stabilizations in the future, that will require testing on real hardware.
