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/thread.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'cpukit/score/src/thread.c') diff --git a/cpukit/score/src/thread.c b/cpukit/score/src/thread.c index c569ae5bab..864b21bf6f 100644 --- a/cpukit/score/src/thread.c +++ b/cpukit/score/src/thread.c @@ -32,9 +32,7 @@ THREAD_OFFSET_ASSERT( Object ); THREAD_OFFSET_ASSERT( Join_queue ); THREAD_OFFSET_ASSERT( current_state ); -THREAD_OFFSET_ASSERT( current_priority ); -THREAD_OFFSET_ASSERT( real_priority ); -THREAD_OFFSET_ASSERT( priority_restore_hint ); +THREAD_OFFSET_ASSERT( Real_priority ); THREAD_OFFSET_ASSERT( resource_count ); THREAD_OFFSET_ASSERT( Scheduler ); THREAD_OFFSET_ASSERT( Wait ); -- cgit v1.2.3
