//! \brief    MOS interface definition
//!
//! Device level: OsDeviceContext in device/Libva context.
//!               The global level of entire media driver instance in user space.
//!               There could be multiple devices in a single process.
//! Stream level: OsStreamState in Hal instances (Codec pipeline, VP pipeline, CM device, CP session, etc)
//!               Each Hal instance can have an OsStreamState to indicate that stream's state specific to OS.
//!               Each Device can have multiple streams.
//!               All OsStreamStates must be binded with a valid OsDeviceContext to indicate the inclusion relationship
//!               between device and stream in DDI
//!
//! MOS interface provide following OS services: (OS services are abstracted and diff OS behavior is tranparent to MOS customers)
//! 1) Workload scheduling (GPU context, cmdbuffer, sync, virtual engine, etc)
//! 2) Resource managment (Graphic resource, external resource)
//! 3) Utilities (Abstraction of generalized system call)
//! 4) Performance interface
//! 5) Debug interface
//!
//! Caller: DDI, Media interface, HAL, MHW
//! Any interface func returning MOS_STATUS_UNKNOWN mean Device level is go into unstable situation.
//! Caller needs to make sure exiting properly.
