How does Linaro schedule OPTEE?

I want to know which part of the code is the scheduler of project OPTEEhttps://github.com/OP-TEE.

More specifically, the code decides that on which CPU secure world and normal word processes are running for multicore architecture.

Any advice is genuinely appreciated.

I'm one of the Linaro developers working directly with OP-TEE and OP-TEE as such has no scheduler, instead it's being entirely scheduled by Linux kernel. It's not tied to a single core either, after being in Linux kernel and you're about to re-enter secure world it could be any of the cores where you continue running your ongoing job. So in short, there is no scheduler in OP-TEE.
