Let’s build out the RISC-V Software Stack in 2016.

Page 3: Arun Thomas BAE Systems 4th RISC-V Workshop, July 2016

Arun’s 2016 RISC-V Wishlist

• Upstream support for GNU toolchain, clang/LLVM, and QEMU

• Upstream support for Linux kernel, Yocto, Gentoo, and BSD

• Debian/RISC-V port

Making Progress• Upstream support for GNU toolchain, clang/LLVM, and QEMU

• Getting ready to send patches for review

• Let’s focus on upstreaming in the next 6 months

• Upstream support for Linux kernel, Yocto, Gentoo, and BSD

• FreeBSD 11 will officially support RISC-V!

• Let’s focus on Linux kernel, Yocto, and Gentoo

• Debian/RISC-V port

• See Manuel’s talk tomorrow

My Take in January

6

Recruit developers

Reduce startup costs

Specs. Docs

My Take in July

7

Foundation should funddevelopers to build

core SW infrastructure

We should decide on a process for proposing ISAenhancements. Start now.

Page 9: Arun Thomas BAE Systems 4th RISC-V Workshop, July 2016

What Might These Folks Do?• Upstreaming and Maintainership

• Porting software to RISC-V

• Performance optimization/analysis

• Enhancing test suites and methodologies

• Continuous integration

• Release management

RISC-V RFCs

• A straw man proposal to spark discussion: github.com/arunthomas/riscv-rfcs.git

• RFCs are written in Markdown text format

• Submit RFCs via GitHub pull requests

• Discussion on isa-dev and GitHub

Summary

• We are making progress on the software stack, but we could move faster

• Foundation should fund software developers

• Community should decide on a process for proposing ISA enhancements
