[PATCH 2/5] score: Fix _Thread_queue_Extract_locked()

[PATCH 5/5] score: Rework MP thread queue callout support

The thread queue implementation was heavily reworked to support SMP. This broke the multiprocessing support of the thread queues. This is fixed by this patch. A thread proxy is unblocked due to three reasons 1) timeout, 2) request satisfaction, and 3) extraction. In case 1) no MPCI

[PATCH 3/5] score: _Thread_queue_Flush() parameter changes

Change _Thread_queue_Flush() into a macro that invokes _Thread_queue_Do_flush() with the parameter set defined by RTEMS_MULTIPROCESSING. For multiprocessing configurations add the object identifier to avoid direct use of the thread wait information. Use mp_ prefix for multiprocessing related

[PATCH 4/5] score: Simplify _Thread_queue_Do_flush()

Also set the thread wait return code for thread proxies since this causes no harm. --- cpukit/score/src/threadqflush.c | 5 + 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/cpukit/score/src/threadqflush.c b/cpukit/score/src/threadqflush.c index 694c746..56dd805 100644 ---
