If you want a proper Unix-like system with official images, FreeBSD is the most solid non-Linux option on RISC-V.

Independent (BSD, FreeBSD kernel + pkg)

Upstream

• Tier 2: the security team doesn't promise timely fixes, and new hardware support lags
• Supported platforms are only Unmatched/Unleashed/VisionFive 2/QEMU/Spike — newer domestic boards are essentially absent
• riscv64sf (soft float) was dropped after 13.5; don't follow old docs
• GPU/wireless driver coverage on RISC-V is far behind x86/arm64, which limits the desktop experience

Status meanings: good — fully usable (desktop boots); basic — basic system (serial console works); part — partial functionality; cft — image exists, needs verification; cfh — documented as supported but fails to boot; cfi — claimed supported, no image; wip — announced only.
