riscv64 core, possible H extension?

[DasAbhi]

Hello I was wondering, is it feasible to add the "H" extension for hypervisors to the 64bit core? Or would that require too much re-engineering of your existing design ?

I am asking because hardware with H extension isn't available for consumers right now, so I am exploring an fpga option. Just wanted to know if it is even possible to add H extension in your riscv64 core.

The hypervisor extension is available.
To enable it, just add new WithHypervisor to any of the 64bit core configs.
I personally have not tried it.

@DasAbhi Did you manage to sythetize the core with the H-extension?

@DasAbhi Hey, did you finish adding H extension to the repo?

Adding new WithHypervusir ++ to src/main/scala/rocket.scala can finish it.
