From 300f6a481aaf9e6d29811faca71bf7104a01492c Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 22 Jun 2016 17:09:23 +0200 Subject: score: Rework thread priority management Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556. --- cpukit/score/src/schedulerstrongapa.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'cpukit/score/src/schedulerstrongapa.c') diff --git a/cpukit/score/src/schedulerstrongapa.c b/cpukit/score/src/schedulerstrongapa.c index 5d7c7f7a1d..fc6d0125e7 100644 --- a/cpukit/score/src/schedulerstrongapa.c +++ b/cpukit/score/src/schedulerstrongapa.c @@ -183,7 +183,12 @@ void _Scheduler_strong_APA_Node_initialize( Scheduler_strong_APA_Node *the_node; the_node = _Scheduler_strong_APA_Node_downcast( node ); - _Scheduler_SMP_Node_initialize( &the_node->Base, the_thread, priority ); + _Scheduler_SMP_Node_initialize( + scheduler, + &the_node->Base, + the_thread, + priority + ); context = _Scheduler_Get_context( scheduler ); self = _Scheduler_strong_APA_Get_self( context ); -- cgit v1.2.3
