PolkaVM is based on RVI20U64, which is a RISC-V profile lacking machine (M) and supervisor (S). The ALU of RVI20U64 has 47 opcodes in total.

I also noted FENCE and FENCE.I are in the profile. Are they useful for a single core CPU package?

Does this architecture have pmpcfg* registers? It would not make any possible sense to me so I’m only sanity checking here.
