Linux Kernel on RISC-V: Where Do We Stand

on YouTube ↗32m

" summary

Linux on RISC‑V already has upstream binutils (Mar 2017), GCC (May 2017), initial kernel patches (Nov 2017), QEMU support (Mar 2018) and distro ports (Debian Feb 2018, Fedora Mar 2018). Development uses BBL + SBI, QEMU for verification, perf/ftrace and remote kgdb; HiFive Unleashed 4‑core is the reference board. Build stats: 3,000-plus builds per week, 85% of builds pass, Debian >80% packages built. Missing work: SBI extensions (power, virtualization), CPU topology, power management, kdump/BPF, huge pages and NUMA.
