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/schedulerdefaultreleasejob.c | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) (limited to 'cpukit/score/src/schedulerdefaultreleasejob.c') diff --git a/cpukit/score/src/schedulerdefaultreleasejob.c b/cpukit/score/src/schedulerdefaultreleasejob.c index 7272fc1946..490d58b05f 100644 --- a/cpukit/score/src/schedulerdefaultreleasejob.c +++ b/cpukit/score/src/schedulerdefaultreleasejob.c @@ -21,26 +21,30 @@ #include -Thread_Control *_Scheduler_default_Release_job( +void _Scheduler_default_Release_job( const Scheduler_Control *scheduler, Thread_Control *the_thread, - uint64_t deadline + Priority_Node *priority_node, + uint64_t deadline, + Thread_queue_Context *queue_context ) { (void) scheduler; (void) the_thread; + (void) priority_node; (void) deadline; - - return NULL; + (void) queue_context; } -Thread_Control *_Scheduler_default_Cancel_job( +void _Scheduler_default_Cancel_job( const Scheduler_Control *scheduler, - Thread_Control *the_thread + Thread_Control *the_thread, + Priority_Node *priority_node, + Thread_queue_Context *queue_context ) { (void) scheduler; (void) the_thread; - - return NULL; + (void) priority_node; + (void) queue_context; } -- cgit v1.2.3
