*	score: Simplify _Thread_Change_priority()	Sebastian Huber	2014-05-15	1	-29/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The function to change a thread priority was too complex. Simplify it with a new scheduler operation. This increases the average case performance due to the simplified logic. The interrupt disabled critical section is a bit prolonged since now the extract, update and enqueue steps are executed atomically. This should however not impact the worst-case interrupt latency since at least for the Deterministic Priority Scheduler this sequence can be carried out with a wee bit of instructions and no loops. Add _Scheduler_Change_priority() to replace the sequence of - _Thread_Set_transient(), - _Scheduler_Extract(), - _Scheduler_Enqueue(), and - _Scheduler_Enqueue_first(). Delete STATES_TRANSIENT, _States_Is_transient() and _Thread_Set_transient() since this state is now superfluous. With this change it is possible to get rid of the SCHEDULER_SMP_NODE_IN_THE_AIR state. This considerably simplifies the implementation of the new SMP locking protocols.
*	score: Static scheduler configuration	Sebastian Huber	2014-04-15	1	-5/+2
\| \| \| \| \| \|	Do not allocate the scheduler control structures from the workspace. This is a preparation step for configuration of clustered/partitioned schedulers on SMP.
*	score: Add scheduler control to scheduler ops	Sebastian Huber	2014-04-04	1	-2/+3
\| \| \| \| \|	Scheduler operations must be free of a global scheduler context to enable partitioned/clustered scheduling.

*	score misc: Clean up Doxygen #3 (GCI 2012)	Alex Ivanov	2012-11-28	1	-2/+7
\| \| \| \| \| \| \|	This patch is a task from GCI 2012 which improves the Doxygen comments in the RTEMS source. http://www.google-melange.com/gci/task/view/google/gci2012/7982215
*	Remove All CVS Id Strings Possible Using a Script	Joel Sherrill	2012-05-11	1	-2/+0
\| \| \| \| \| \| \| \| \| \| \| \|	Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

	PR 1743/cpu * sapi/include/confdefs.h, score/Makefile.am, score/preinstall.am: Add Simple Priority Scheduler as complement to existing Deterministic Priority Scheduler. This scheduler serves both as an example and as a lighter weight implementation for smaller systems. * score/include/rtems/score/schedulersimple.h, score/inline/rtems/score/schedulersimple.inl, score/src/schedulersimple.c, score/src/schedulersimpleblock.c, score/src/schedulersimpleenqueue.c, score/src/schedulersimpleenqueuefirst.c, score/src/schedulersimpleextract.c, score/src/schedulersimplereadyqueueenqueue.c, score/src/schedulersimplereadyqueueenqueuefirst.c, score/src/schedulersimpleschedule.c, score/src/schedulersimpleunblock.c, score/src/schedulersimpleyield.c: New files.
