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. --- testsuites/sptests/spsem03/spsem03.doc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'testsuites/sptests/spsem03/spsem03.doc') diff --git a/testsuites/sptests/spsem03/spsem03.doc b/testsuites/sptests/spsem03/spsem03.doc index 0310965798..a13430e874 100644 --- a/testsuites/sptests/spsem03/spsem03.doc +++ b/testsuites/sptests/spsem03/spsem03.doc @@ -8,5 +8,5 @@ directives: concepts: - - Demonstrate that the priority inheritance protocol doesn't propagate to - indirectly referenced semaphore owners. + - Demonstrate that the priority inheritance protocol works with indirectly + referenced semaphore owners. -- cgit v1.2.3
