RISC-V is making moves, but it has work to do if it wants to hit the mainstream (theregister.com)
RISC-V has been talked up as a challenger to Arm and x86, offering an open royalty-free architecture that promises flexibility and innovation without licensing costs. But for all the noise, you're more likely to find it buried inside IoT gadgets and obscure embedded systems than powering anything that'll typically grab a headline.

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.
