Experiences with NOMMU Linux for RISC-V platform bring-up and validation
Description
The RISER project aims to build accelerator and microserver
systems based on RISC-V SoCs from ongoing European projects funded by the EuroHPC JU.
Working with experimental hardware platforms requires substantial effort on
verification and bring-up, including bare-metal tests aimed at the core, memory, and
platform levels. Booting a full-blown Linux distribution greatly expands test coverage but
also complexity. We recommend starting with a bare-minimum kernel configuration, without
networking and storage functions, and even opting for a no-MMU system configuration, to
progressively expand test coverage. In this talk, we outline the features and limitations of
no-MMU and summarize our practical experience in early-stage verification of RISC-V prototype platforms.
