RISC-V is an open source Instruction Set Architecture (ISA) + designed at UC Berkeley. It is freely available for all uses + without requiring fees or license agreements. + The RISC-V team intends to provide freely available + BSD licensed CPU designs.

+ +

&a.br; (University of Cambridge) now has &os; booting + to a single user shell on a RISC-V simulator. + The porting effort started only two months ago + and is very much a work in progress, requiring significant + refactoring and clean up before it reaches a committable + state. Nonetheless this is exceptional progress in a short + time. The porting effort also identified a number of + proposed ISA improvements.

+ +

The port currently uses the GNU tool chain (GCC and + binutils), and runs on the Spike simulator. Improved RISC-V + support in Clang/LLVM and related tools is highly desired.
