Working with Igalia to Improve RISC-V LLVM Continuous Integration (riseproject.dev)
The LLVM project provides a very widely used and actively developed suite of compiler and toolchain technologies: including Clang, the LLVM middle-end optimizer and backend code generator, MLIR, LLD linker, and much more. While RISC-V LLVM support has progressed significantly, a key area that needed attention was the limited level of continuous integration (CI) for the RISC-V target.

RISC-V is currently slow compared to modern CPUs (benhouston3d.com)
After watching the rise of ARM displace Intel from most of my personal and server computing, I've been following the RISC-V architecture with intense interest. It's an exciting open-source ISA that has the potential to reshape the CPU landscape, but there's an important caveat: RISC-V is currently quite slow compared to modern CPUs in 2024. It is even slow compared to Raspberry PI boards.

Software-defined processors: the promise of RISC-V (redhat.com)
It’s an exciting time to be involved in open source. Linux powers the world’s most critical devices, a story to which Red Hat has always been a champion. Today we look further afield. We look to a world of not what “is” but what “could be”. It’s informed by the path we’ve walked and the lessons we’ve learned along the way. It’s a story of re-aligning goals in the spirit of community.
