Evolution of the RISC-V ISA. What Next After RVA23?
Ubuntu, Tuesday, September 15th, 2026
Canonical reviews how the RISC-V instruction set is evolving and what follows the RVA23 profile.
Canonical traces the development of the RISC-V instruction set architecture and the role profiles play in making the ecosystem coherent.
The post explains what RVA23 standardized and why profile-based targeting matters for distributions and software vendors.
It looks ahead to the extensions and profile work expected next, including implications for vector, virtualization, and security features. Ubuntu's own RISC-V support strategy is discussed in that context.
