The RISC-V project is an effort to bring first-class RISC-V CPU architecture support in Gentoo.
Status
Experimental stages are available, and a minimum set of packages in the Gentoo repository is keyworded.
qemu-riscv can run the binaries just fine: qemu-riscv64 -L /usr/riscv64-unknown-linux-gnu/ /usr/riscv64-unknown-linux-gnu/bin/bash This way you can also test in an emulated chroot.
What needs to be done
Things to happen yet:
- TODO: Make stage3 autobuilds.
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.
Documentation
- TODO: Describe arch-specific gotchas (alignment requirements, immediate encodings, PIC story).
- TODO: Add external links to ISA and ABI docs.
- RISC-V ABIs
- RISC-V Multilib
