Linux-libre on RISC-V

Jason Self at

I've started building Linux-libre kernel packages for RISC-V, starting with version 4.19.1.

Since there isn't a standard RISC-V architecture you might ask which RISC-V? I mean the 64-bit little-endian variant. More specifically, -march=rv64imafdc or RV64GC for short. This seems to be what's been agreed on by major GNU/Linux distros.

I normally build all supported kernel versions on all supported architectures. In the case of RISC-V, though, versions older than 4.19 won't be supported since they lack the necessary drivers in upstream. This is the minimum version needed to boot into userland without patches.

This brings the total number of supported architectures to 7. In alphabetical order:

amd64 arm64 armhf i386 ppc64el riscv64 s390x

The master server has been updated. The mirrors will sync up over the next few days.
