Communication between enclaves and Linux

[ApoChagi]

Hello,
I am currently experimenting with multizone-linux on Unleashed U540 board. After reading the specifications and the provided manuals (both in this repo and the corresponding in https://github.com/hex-five/multizone-sdk) I have few questions to ask.

1. Is it possible for a Linux process to communicate with an enclave app (regarding that enclaves run in a different core)?
2. Is it possible for an enclave app to read CSR registers from the Linux cores? To my understanding, MultiZone IPC runs in both 5 cores. So, is there a way to modify MultiZone IPC in order to export (let's say as a function) the CSR registers of the 4 remaining cores (or at least one of them)?

Thanks in advance!
