RISC-V Ecosystem Gets More Standardization as Ubuntu Drops Non-Compliant CPUs

Ubuntu 25.10 release to mandate RVA23 profile, obsoleting most RISC-V hardware - CNX Software

RISC-V is an open architecture standard that provides flexibility, and chip designers can add or remove instructions as they please to match their application requirements. That’s all great until complex software designed to run on multiple platforms is involved. That’s why for Linux and Android support, the RVA (RISC-V Application) profiles were created, so that every RISC-V SoC designed for those systems meets some minimal requirements and sha…

RISC-V Ecosystem Gets More Standardization as Ubuntu Drops Non-Compliant CPUs

Canonical, the company behind Ubuntu, has announced that its next-generation release will require RISC‑V processors to meet the newly ratified RVA23 profile. This specification, approved back in April, includes full support for Vector Instructions 1.0 and a Hypervisor extension. As Laurine Kirk, security researcher at Google, notes, by setting this higher baseline, Ubuntu 26.04 will no longer run on roughly 90% of existing RISC-V single-board co…
