Detailed Description

This group contains the implementation to support the Semaphore Manager in multiprocessing (MP) configurations.

Enumeration Type Documentation

Semaphore_MP_Remote_operations

enum Semaphore_MP_Remote_operations

The following enumerated type defines the list of remote semaphore operations.

Function Documentation

_Semaphore_Core_mutex_mp_support()

void _Semaphore_Core_mutex_mp_support	(	Thread_Control *	the_thread,
		Objects_Id	id
	)

Semaphore Core Mutex MP Support.

This function processes the global actions necessary for remote accesses to a global semaphore based on a core mutex. This function is called by the core.

Parameters

[in]	the_thread	the remote thread the semaphore was surrendered to
[in]	id	is the id of the surrendered semaphore

_Semaphore_Core_semaphore_mp_support()

void _Semaphore_Core_semaphore_mp_support	(	Thread_Control *	the_thread,
		Objects_Id	id
	)

Semaphore Core MP Support.

This function processes the global actions necessary for remote accesses to a global semaphore based on a core semaphore. This function is called by the core.

Parameters

[in]	the_thread	the remote thread the semaphore was surrendered to
[in]	id	is the id of the surrendered semaphore

_Semaphore_MP_Send_object_was_deleted()

void _Semaphore_MP_Send_object_was_deleted	(	Thread_Control *	the_proxy,
		Objects_Id	mp_id
	)

Semaphore MP Send Object was Deleted.

This routine is invoked indirectly by the thread queue when a proxy has been removed from the thread queue and the remote node must be informed of this.

_Semaphore_MP_Send_process_packet()

void _Semaphore_MP_Send_process_packet	(	Semaphore_MP_Remote_operations	operation,
		Objects_Id	semaphore_id,
		rtems_name	name,
		Objects_Id	proxy_id
	)

Semaphore MP Send Process Packet.

This routine performs a remote procedure call so that a process operation can be performed on another node.
