What do you mean by an upcall here? |

This is related to #556 and #564. Basically, we want to make the platform be unaware of OP-TEE stuffs. The platform delegates any OP-TEE commands to the runner and the shim via an upcall (technically, just a callback), and they will handle those commands. |

LGTM!. I am not familiar with the register handling, so not approving the PR. |

There was a problem hiding this comment.
Overall, the code looks good to me. I left some comments below.

This PR adds `run_thread` support for LVBS platform and revise its syscall handling routine based on Linux userland platform's syscall handling. It has suppressed new page table creation for now because it needs to be done by the runner via an upcall (userspace support still exists, but doesn't create a separate one for each TA instance for now). --------- Co-authored-by: Sangho Lee <sanghle@microsoft.com>
