Description Yixun Lan archtester gentoo-dev 2021-01-30 08:00:23 UTC 
this bug request to add support for building kernel (sys-kernel/gentoo-sources) for ARCH Risc-V.

I have one patch which need review, and already successfully build/run kernel (tested with sys-kernel/gentoo-sources version 5.8.7, 5.10.11) for Risc-V on sifive unleashed board

Reproducible: Always
