Ubuntu 25.10's Only Supported RISC-V Platform: QEMU Virtualization
Back in June it was announced by Canonical that for the Ubuntu 25.10 release they would be raising the RISC-V baseline to the RVA23 profile even with barely any available RISC-V platforms supporting that newer RISC-V profile
That change is still going ahead and leaves Ubuntu 25.10 on RISC-V currently only supporting the QEMU virtualized target. The mandatory set includes for instance scalable vector support and pointer masking which will both help to bring the architecture to an execution speed comparable to ARM and x86. Optional extensions include control flow integrity and vector crypto support.
