Open-source SPMP-based CVA6 Virtualization
| Resumo: | This work presents the first open-source design and implementation of the RISC-V SPMP for hypervisor. We integrated the dual-stage SPMP implementation into an MMU-less 64-bit CVA6 core with the Hypervisor extension enabled. The modified core was functionally validated using a software stack built around the Bao hypervisor. Preliminary results regarding FPGA resource utilization are also provided. Future work includes benchmarking the SPMP-based platform and comparing its performance with conventional MMU-based virtualization. Additionally, we plan to contribute to the RISC-V community by developing a QEMU implementation of the dual-stage SPMP. |
