What is the SPMP branch status of bao?

Hi,

PMP-based virtualization will trap multiple times, which greatly affects performance. I decided to use the SPMP which is still under development. And the Shpmp could be the next step( It seems that no qemu or spike has implemented Shpmp ).

I have some questions about SPMP:

• What is the SPMP branch status of bao? https://github.com/josecm/bao-hypervisor/tree/exp/spmp
• Where to get the SPMP version of spike?

Thanks in advance!

hello @yangn0. Sorry for the delay. That branch ir purely experimental since the spec for hypervisor SPMP it is still evolving. I am actually one of the editors of the spec. When it reaches a more mature state we will reimpliment that support and add it to this official repo.

Are you working on something similar? Let me know how we can help
