Function sys_thread_resume_from_upcall

pub unsafe fn sys_thread_resume_from_upcall(
    frame: &UpcallFrame,
    flags: ResumeFlags,
) -> !

Resume from an upcall, restoring registers. If you can resume yourself in userspace, this call is not necessary.

Safety

The frame argument must point to a valid upcall frame with a valid register state.
