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/Makefile.am | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'cpukit/score/Makefile.am') diff --git a/cpukit/score/Makefile.am b/cpukit/score/Makefile.am index f18af7d4e6..a196ff5dae 100644 --- a/cpukit/score/Makefile.am +++ b/cpukit/score/Makefile.am @@ -58,6 +58,7 @@ include_rtems_score_HEADERS += include/rtems/score/objectimpl.h include_rtems_score_HEADERS += include/rtems/score/onceimpl.h include_rtems_score_HEADERS += include/rtems/score/percpu.h include_rtems_score_HEADERS += include/rtems/score/priority.h +include_rtems_score_HEADERS += include/rtems/score/priorityimpl.h include_rtems_score_HEADERS += include/rtems/score/prioritybitmap.h include_rtems_score_HEADERS += include/rtems/score/prioritybitmapimpl.h include_rtems_score_HEADERS += include/rtems/score/profiling.h @@ -300,7 +301,7 @@ libscore_a_SOURCES += src/thread.c src/threadchangepriority.c \ src/threaddispatch.c \ src/threadget.c src/threadhandler.c src/threadinitialize.c \ src/threadloadenv.c \ - src/threadrestart.c src/threadsetpriority.c \ + src/threadrestart.c \ src/threadsetstate.c \ src/threadstackallocate.c src/threadstackfree.c src/threadstart.c \ src/threadstartmultitasking.c src/iterateoverthreads.c -- cgit v1.2.3
