*	score: Improve SMP lock debug support	Sebastian Huber	2017-01-11	1	-1/+1
\| \| \| \| \|	The CPU index starts with zero. Increment it by one, to allow global SMP locks to reside in the BSS section.
*	score: Inline some SMP lock operations by default	Sebastian Huber	2016-11-09	1	-0/+4
\| \| \| \| \| \| \| \| \|	The SMP ticket lock release turned out to be suitable for inlining, e.g. a hand full of instructions, no branches. The changes in the screen files do not reflect the changes due to this commit. However, they are now up to date. Obtained on a T4240 running at 1.5GHz using GCC 7.0.0 20161108..
*	score: Default to non-inline SMP lock ops	Sebastian Huber	2016-11-04	1	-36/+7
\| \| \| \| \|	Use non-inline SMP lock acquire and release operations by default. Provide inline variants for the hot spots, e.g. mutex acquire/release.
*	score: Rename _ISR_Disable_without_giant()	Sebastian Huber	2016-05-20	1	-1/+1
\| \| \| \| \| \| \| \| \|	Rename _ISR_Disable_without_giant() into _ISR_Local_disable(). Rename _ISR_Enable_without_giant() into _ISR_Local_enable(). This is a preparation to remove the Giant lock. Update #2555.
*	score: Ensure matching lock acquire and release	Sebastian Huber	2016-05-12	1	-1/+12
\| \| \| \| \|	Ensure matching lock acquire and release for SMP locks if RTEMS_DEBUG is defined.
*	score: Add _ISR_lock_Is_owner()	Sebastian Huber	2016-05-12	1	-1/+24

*	score: Do not inline SMP lock if profiling enabled	Sebastian Huber	2015-05-19	1	-0/+68
\| \| \| \|	This reduces the code size drastically.
*	smp: New SMP lock API	Sebastian Huber	2013-05-31	1	-285/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Move the SMP lock implementation to the CPU port. An optimal SMP lock implementation is highly architecture dependent. For example the memory models may be fundamentally different. The new SMP lock API has a flaw. It does not provide the ability to use a local context for acquire and release pairs. Such a context is necessary to implement for example the Mellor-Crummey and Scott (MCS) locks. The SMP lock is currently used in _Thread_Disable_dispatch() and _Thread_Enable_dispatch() and makes them to a giant lock acquire and release. Since these functions do not pass state information via a local context there is currently no use case for such a feature.
*	score misc: Clean up Doxygen #3 (GCI 2012)	Alex Ivanov	2012-11-28	1	-6/+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.
*	2011-10-17 Daniel Hellstrom <daniel@gaisler.com>	Jennifer Averett	2011-10-17	1	-2/+5
\| \| \| \| \| \| \|	PR 1935/cpukit * score/include/rtems/score/smplock.h, score/src/smplock.c: SMP nested count variable was being overritten when nested lock was taken more than once.
*	2011-08-22 Jennifer Averett <Jennifer.Averett@OARcorp.com>	Jennifer Averett	2011-08-22	1	-27/+203
\| \| \| \| \| \| \| \|	PR 1876 * score/Makefile.am, score/include/rtems/score/isr.h, score/src/isr.c, score/src/smp.c, score/src/smplock.c, score/src/threaddispatch.c, score/src/threaddispatchdisablelevel.c: Add smp isr support. * score/src/isrsmp.c: New file.

\| \| \| \| \| \| \|	PR 1787/cpukit * score/include/rtems/score/percpu.h, score/include/rtems/score/smplock.h, score/src/smp.c, score/src/smplock.c: Add nesting support to smp spinlock.

	PR 1729/cpukit * configure.ac, sapi/include/confdefs.h, sapi/src/exinit.c, score/Makefile.am, score/preinstall.am, score/cpu/i386/rtems/score/cpu.h, score/cpu/sparc/cpu_asm.S, score/cpu/sparc/rtems/score/cpu.h, score/include/rtems/score/basedefs.h, score/include/rtems/score/context.h, score/include/rtems/score/percpu.h, score/src/percpu.c, score/src/thread.c, score/src/threadcreateidle.c: Add next step in SMP support. This adds an allocated array of the Per_CPU structures to support multiple cpus vs a single instance of the structure which is still used if SMP support is disabled. Configuration support is also added to explicitly enable or disable SMP. But SMP can only be enabled for the CPUs which will support it initially -- SPARC and i386. With the stub BSP support, a BSP can be run as a single core SMP system from an RTEMS data structure standpoint. * aclocal/check-smp.m4, aclocal/enable-smp.m4, score/include/rtems/bspsmp.h, score/include/rtems/score/smplock.h, score/src/smp.c, score/src/smplock.c: New files.
