Detailed Description

This handler encapsulates functionality which is related to managing threads in a multiprocessor system configuration. This handler must manage proxies which represent remote threads blocking on local operations.

Thread_Control* _Thread_MP_Allocate_proxy

(

States_Control

the_state

)

_Thread_MP_Allocate_proxy

This allocates a proxy control block from the inactive chain of free proxy control blocks.

Note:

This function returns a thread control pointer because proxies are substitutes for remote threads.

Thread_Control* _Thread_MP_Find_proxy

(

Objects_Id

the_id

)

_Thread_MP_Find_proxy

This function removes the proxy control block for the specified id from the active chain of proxy control blocks.

RTEMS_INLINE_ROUTINE void _Thread_MP_Free_proxy

(

Thread_Control *

the_thread

)

This routine frees a proxy control block to the inactive chain of free proxy control blocks.

References _Chain_Append(), _Chain_Extract(), _Thread_MP_Inactive_proxies, Thread_Proxy_control::Active, Objects_Control::Node, and Thread_Control_struct::Object.

void _Thread_MP_Handler_initialization

(

uint32_t

maximum_proxies

)

_Thread_MP_Handler_initialization

This routine initializes the multiprocessing portion of the Thread Handler.

RTEMS_INLINE_ROUTINE boolean _Thread_MP_Is_receive

(

Thread_Control *

the_thread

)

This function returns true if the thread in question is the multiprocessing receive thread.
