Introduce Thread_queue_Lock_context to contain the context necessary for
thread queue lock and thread wait lock acquire/release operations to
reduce the Thread_Control size.

Remove superfluous support for simple binary semaphores. With this we
can get rid of the CORE_MUTEX_NESTING_BLOCKS variant.

Add _Thread_queue_Context_set_MP_callout() to simplify
_Thread_queue_Context_initialize(). This makes it possible to more
easily add additional fields to Thread_queue_Context.

Drop the multiprocessing (MP) dependent callout parameter from the
thread queue extract, dequeue, flush and unblock methods. Merge this
parameter with the lock context into new structure Thread_queue_Context.
This helps to gets rid of the conditionally compiled method call
helpers.

Uniformly use *_Get() to get an object by identifier with a lock
context.

Use _Objects_Get_local() for _Semaphore_Get_interrupt_disable() to get
rid of the location parameter. Move remote object handling to semaphore
MPCI support.
|
| |
|
|
|
|
| |
Use _Semaphore_Get_interrupt_disable() instead.
Update #2555.

Use thread wait flags for synchronization. The enqueue operation is now
part of the initial critical section. This is the key change and
enables fine grained locking on SMP for objects using a thread queue
like semaphores and message queues.
Update #2273.
