From ArchWiki

I use Arch Linux on AMD64 and ARMv7h architectures, and I hope, quickly on RISC-V architecture too. I use it mainly for work, as workstation and for graphics leisure stuff. Some years of experience on both LinuxFromScratch, Debian, Ubuntu and Slackware (among other distros I used).

RISC-V: Have some RV32 & RV64 microcontroller boards, managed to run Debian on RV64 arch on qemu and some other basics systems. Next step, try Arch. Some full (not microcontroller only) affordable microprocessor boards with low computer power (only for devs/integrators) should be available this or next month (may/june 2021).
