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/scheduleredfnodeinit.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'cpukit/score/src/scheduleredfnodeinit.c') diff --git a/cpukit/score/src/scheduleredfnodeinit.c b/cpukit/score/src/scheduleredfnodeinit.c index d290bd74fd..94f8facbe3 100644 --- a/cpukit/score/src/scheduleredfnodeinit.c +++ b/cpukit/score/src/scheduleredfnodeinit.c @@ -29,11 +29,9 @@ void _Scheduler_EDF_Node_initialize( { Scheduler_EDF_Node *the_node; - (void) scheduler; - - _Scheduler_Node_do_initialize( node, the_thread, priority ); + _Scheduler_Node_do_initialize( scheduler, node, the_thread, priority ); the_node = _Scheduler_EDF_Node_downcast( node ); - the_node->thread = the_thread; _RBTree_Initialize_node( &the_node->Node ); + the_node->priority = priority; } -- cgit v1.2.3
