AUTOSAR Classic Operating System

This callback function can be configured for the receiver of a communication. If configured, IOC calls this callback on the receiving core for each data reception. is the callback function name configured by the receiver in the Os Ioc Re ceiver Pull CB attribute to be called on data reception."

This service determines if the OS - Applications, given by Appl ID, is allowed to use the IDs of a Task, Resource, Counter, Alarm or Schedule Table in API calls.

Asynchronous version of the Activate Task() function. Intended to be used for cross core task activation. Possible errors are not returned to the caller, but may be reported via error hooks.

This service sets the own state of an OS - Application from AP PLICATION_ RESTARTING to APPLICATION_ ACCESSIBLE.

A (trusted or non - trusted) OS - Application uses this service to call a trusted function

This service checks if a memory region is write/ read/ execute accessible and also returns information if the memory region is part of the stack space.

This service determines to which OS - Application a given Task, ISR, Counter, Alarm or Schedule Table belongs

This service checks if a memory region is write/ read/ execu te accessible and also returns information if the memory region is part of the stack space.

Service ClearPendingInterrupt.

This API allows the caller to select the idle mode action which is performed during idle time of t he OS (e.g. if no Task/ ISR is active). It can be used to implement energy savings. The real idle modes are hardware dependent and not standardized. The default idle mode on each core is IDLE_ NO_ HALT.

Disables the interrupt source by modifying the interrupt controller registers.

Service EnableInterruptSource.

This service determines the OS - Application (a unique identifier has to be allocated to each application) where the caller originally belongs to (was configured t o).

This service returns the current state of an OS - Application.

The function returns a unique core identifier.

This service reads the current count value of a counte r (returning either the hardware timer ticks if counter is driven by hardware or the software ticks when user drives counter).

This service determines the OS - Application where the caller of the service is currently executing. Note that if the caller is not within a Call Trusted Function() call the value is eq ual to the result of Get Application ID().

This service gets the number of ticks between the current tick value and a previously read tick value.

This service returns the identifier of the currently executing ISR.

The function returns the number of cores activated by the Start Core function. This function might be a macro. AUTOSAR CP R20 - o f Document ID : AUTOSAR_SWS_OS

This service queries the state of a schedule table (also with respect to synchronization).

Get Spinlock tries to occupy a spin - lock variable. If the function returns, either the lock is successfully taken or an error has occurred. The spinlock mechanism is an active polling mechanism. The function does not cause a de - scheduling.

This service increments a software counter.

This service initializes the data structures of the IOC. Tags: atp.Status=draft

This service modifies a given memory location () with the formula: * = ((* & ) | )

This service modifies a given memory location () with the formula: * = ((* & ) | )

This service modifies a given memory location () with the formula: * = ((* & ) | )

This service switches the processing from one schedule table to another schedule table.

The protection hook is always called if a serious error occurs. E.g. exceeding the worst case execution time or violating against the memory protection.

This service returns the content of a given memory location (

Release Spinlock releases a spinlock variable that was occupied before. Before terminating a TASK all spinlock variables that have been occupied with Get Spinlock() shall be released. Before calling Wait EVENT all Spinlocks shall be released.

Asynchronous version of the Set Event() function. Intended to be used for cross core event setting. Possible errors are not returned to the caller, but may be reported via error hooks.

This service stops synchronization of a schedule table.

After this service the OS on all AUTOSAR cores is shut down. Allowed at TASK level and ISR level and also internally by the OS. The function will never return. The function will force other cores into a shutdown.

It is not supported to call this function after Start OS(). The function starts the core specified by the parameter Core ID. The OUT parameter allows the caller to check whether the operation was successful or no t. If a core is started by means of this function Start OS shall be called on the core.

The function start s the core specified by the parameter Core ID. It is allowed to call this function after Start OS(). The OUT parameter allows the caller to check whether the operation was successful or not. It is not allowed to call Start OS on cores activated by Start No n Autosar Core. Otherwise the behaviour is unspecified.

This service starts the processing o f a schedule table at an absolute value "Start" on the underlying counter.

This service starts the processing of a schedule table at "Offset" relative to the "Now" value on the underlying counter.

This service starts an explicitly synchronized schedule table synchronously.

This service cancels the processing of a schedule table immediately at any point while the schedule table is running.

Service SyncScheduleTable.

Service TerminateApplication.

Try To Get Spinlock has the same functionality as Get Spinlock with the difference that if the spinlock is already occupied by a TASK on a d ifferent core the function sets the OUT parameter "Success" and returns with E_ OK.

This service writes the to a given memory location (). Available vi a Os.h

This type holds information how a specific memory region can be accessed.

This data type represents an AUTOSAR OS alarm identifier.

This data type points to location where a Application State Type can be stored.

This data type identifies the state of an OS - Application. AUTOSAR CP R20 - o f Document ID : AUTOSAR_SWS_OS

This data type identifies the OS - Application.

This data type points to a variable of the data type Schedule Table Status Type.

This type describes the status of a schedule. The status can be one of the following: o The schedule table is not started (SCHEDULETABLE_ STOPPED) o The schedule table will be started after the end of currently running schedule table (sched ule table was used in Next Schedule Table() service) (SCHEDULETABLE_ NEXT) o The schedule table uses explicit synchronization, has been started and is waiting for the global time. (SCHEDULETABLE_ WAITING) o The schedule table is running, but is currently n ot synchronous to a global time source (SCHEDULETABLE_ RUNNING) o The schedule table is running and is synchronous to a global time source (SCHEDULETABLE_ RUNNING_ AND_ SYNCHRONOUS)

This data type identifies a schedule table.
