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/threadtimeout.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'cpukit/score/src/threadtimeout.c') diff --git a/cpukit/score/src/threadtimeout.c b/cpukit/score/src/threadtimeout.c index b6b6cc4ac2..8297c55c4b 100644 --- a/cpukit/score/src/threadtimeout.c +++ b/cpukit/score/src/threadtimeout.c @@ -30,6 +30,8 @@ void _Thread_Timeout( Watchdog_Control *watchdog ) bool unblock; the_thread = RTEMS_CONTAINER_OF( watchdog, Thread_Control, Timer.Watchdog ); + + _Thread_queue_Context_clear_priority_updates( &queue_context ); _Thread_Wait_acquire( the_thread, &queue_context ); wait_flags = _Thread_Wait_flags_get( the_thread ); @@ -66,6 +68,7 @@ void _Thread_Timeout( Watchdog_Control *watchdog ) } _Thread_Wait_release( the_thread, &queue_context ); + _Thread_Priority_update( &queue_context ); if ( unblock ) { _Thread_Wait_tranquilize( the_thread ); -- cgit v1.2.3
