* @defgroup nvsci_ipc_event Event Service APIs
*
* @ingroup nvsci_group_ipc
* @{
*
* The NvSciEventService library provides the ability to build portable
* event-driven applications.
* An event is any significant occurrence or change in the state for system hardware
* or software. An event notification is a message or notification sent by one
* software part to another to convey that an event has taken place.
* An event-driven model consists of an event producer and event consumers.
* Once an event producer detects an event, it represents the event as
* a message (or notification). An event is transmitted from an event producer to
* event consumers through an OS-specific event channel.
* Event consumers must be informed when an event has occurred.
* NvSciEventService will execute the correct response (or callback)
* to an event.
*
* NvSciEventService provides a mandatory abstract interface between
* other SCI technologies (especially NvSciIpc and NvSciStreams) and
* the application-provided event loop that services them.
*
* The following common object type(s) are implemented:
*
* - User-visible object types (for application use)
* - NvSciEventService: An object that subsumes all state that commonly would
* have been maintained in global variables.
* - NvSciEventNotifier: An object that a library creates using an
* NvSciEventService and then provides to the user, and with which the user
* registers an event handler that is invoked whenever the library
* generates an event.
* - NvSciLocalEvent: An object with which a library can signal events
* directly, without going through environment-specific mechanisms. Local
* events are limited to cases where the signaler and waiter are in the
* same process, but may be more efficient than environment-specific
* notifiers (which typically pass through an OS).
*
* - Non-user-visible object types (for integrating libraries with an
* NvSciEventService)
* - NvSciNativeEvent: An object that a library fills in with
* environment-specific information that is necessary for an event service
* to wait for environment-specific events (from OS or other event
* producers).
*
* <b>Typical call flow with NvSciIpc library</b>
*
* 1) Init mode
* - NvSciEventLoopServiceCreateSafe()
* - NvSciIpcInit()
* - NvSciIpcOpenEndpointWithEventService()
* - NvSciIpcGetEventNotifier()
* - NvSciEventNotifier::SetHandler() // This is optional for event handler
* - NvSciIpcGetEndpointInfo()
* - NvSciIpcResetEndpoint()
* - Ensure a channel is established
* ~~~~~~~~~~~~~~~~~~~~~
* loop {
* NvSciIpcGetEvent()
* if (event & NV_SCI_IPC_EVENT_CONN_EST_ALL) break
* else {
* // The event handler will be called inside of WaitForXXX() if
* // the handler is registered by NvSciEventNotifier::SetHandler()
* // and the corresponding event is detected
* NvSciEventLoopService::WaitForEvent()
* or
* NvSciEventLoopService::WaitForMultipleEvents()
* or

* 2) Runtime mode (loop)
* - NvSciIpcGetEvent()
* - If an event is not desired,
* NvSciEventLoopService::WaitForEvent()
* or
* NvSciEventLoopService::WaitForMultipleEvents()
* or

* - NvSciIpcRead() or NvSciIpcWrite()
*
* 3) Deinit mode
* - If an eventNotifier is not required any more,

* handling:
*
* (1) The ability to define "event notifiers", which are objects that can
* notify event handling infrastructure each time an event has occurred.
* Note that event notifications carry no payload; it is expected that any
* event payload information is conveyed separately.
*
* (2) The ability to bind an "event handler" to each event notifier. An event
* handler is essentially a callback that is invoked each time the bound
* event notifier reports the occurrence of an event.

* - A data structure used by the public interfaces is modified.
* - Existing message formats used by IPC blocks to communicate between

* section NvSciStream logical data types
* Block: A block is a modular portion of a stream which resides
* in a single process and manages one aspect of the stream's
* behavior. Blocks are connected together in a tree to form
* arbitrary streams.
*
* NvSciStream supports the following types of blocks:
* - Producer: Producer is a type of block responsible for
* generating stream data. Each stream begins with a producer
* block, it is also referred to as the upstream endpoint of the
* stream.
*
* - Consumer: Consumer is a type of block responsible for
* processing stream data. Each stream ends with one or
* more consumer blocks, it is also referred to as the
* downstream endpoint of the stream.
*
* - Pool: Pool is a type of block containing the set of
* packets available for use by @a Producer. NvSciStream
* supports only a static pool in which the number of
* packets managed by the pool is fixed when the pool
* is created.
*
* - Queue: Queue is a type of block containing set of
* packets available for use by @a Consumer.
* NvSciStream supports two types of queue blocks:
* - Fifo: A Fifo Queue block is used when all
* packets must be acquired by the consumer in
* the order received. Packets will wait in the FIFO
* until the consumer acquires them.
* - Mailbox: Mailbox Queue block is used when the consumer
* should acquire the most recent data. If a new
* packet is inserted in the mailbox when one
* is already waiting, the previous one will be skipped
* and its buffers will immediately be returned to the
* Producer for reuse.
*
* - Multicast: Multicast is a type of block which is responsible
* for connecting separate pipelines when a stream has more than
* one Consumer.
*
* - IpcSrc - IpcSrc is a type of block which is the upstream
* half of an IPC block pair which allows NvSciSyncObj waiter
* requirements, NvSciSyncObj(s), packet element
* information and packets to be transmitted to or received from
* the downstream half of the stream which resides in another
* process.
*
* - IpcDst - IpcDst is a type of block which is the downstream
* half of an IPC block pair which allows NvSciSyncObj waiter
* requirements, NvSciSyncObj(s), packet element
* information and packets to be transmitted to or received from
* the upstream half of the stream which resides in another process.
*
* Packet: A packet represents a set of NvSciBufObjs containing stream
* data, each NvSciBufObj it contains is also referred to as an element
* of the packet.
