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/rtems/src/ratemoncreate.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'cpukit/rtems/src/ratemoncreate.c') diff --git a/cpukit/rtems/src/ratemoncreate.c b/cpukit/rtems/src/ratemoncreate.c index a86c6a1eeb..12327295ac 100644 --- a/cpukit/rtems/src/ratemoncreate.c +++ b/cpukit/rtems/src/ratemoncreate.c @@ -63,6 +63,8 @@ rtems_status_code rtems_rate_monotonic_create( } _ISR_lock_Initialize( &the_period->Lock, "Rate Monotonic Period" ); + _Priority_Node_initialize( &the_period->Priority, 0 ); + _Priority_Node_set_inactive( &the_period->Priority ); the_period->owner = _Thread_Get_executing(); the_period->state = RATE_MONOTONIC_INACTIVE; -- cgit v1.2.3
