      SBI (Supervisor Binary Interface) is an interface between the Supervisor Execution Environment (SEE) and the supervisor. It allows the supervisor to execute some privileged operations by using the ecall instruction. Examples of SEE and supervisor are: M-Mode and S-Mode on Unix-class platforms, where SBI is the only interface between them, as well as the Hypervisor extended-Supervisor (HS) and Virtualized Supervisor (VS).
