This significantly can reduce context - switch latency under certain circumstances. In particular, - some heap/region operations were O(n) and had dispatching - disabled. This should help enormously. With this merge, - the patch is not as clean as it should be. In particular, - the documentation has not been modified to reflect the new object - ID layout, the IDs in the test screens are not updated, and - _Objects_Get_information needs to be a real routine not inlined. - As part of this patch a lot of MP code for thread/proxy blocking - was made conditional and cleaned up. - * include/Makefile.am, include/rtems/score/coremsg.h, - include/rtems/score/coremutex.h, include/rtems/score/coresem.h, - include/rtems/score/object.h, include/rtems/score/threadq.h, - inline/rtems/score/object.inl, inline/rtems/score/thread.inl, - macros/rtems/score/object.inl, src/Makefile.am, src/coremsg.c, - src/coremutex.c, src/coresem.c, src/mpci.c, - src/objectcomparenameraw.c, src/objectextendinformation.c, - src/objectinitializeinformation.c, src/objectnametoid.c, - src/thread.c, src/threadclose.c, src/threadget.c, src/threadq.c, - src/threadqextractwithproxy.c: Modified as part of above. - * include/rtems/score/apimutex.h, src/objectgetnoprotection.c: New - files. - -2001-05-17 Joel Sherrill <joel@OARcorp.com> - - * macros/rtems/score/thread..inl: Implemented missing routines - for new libc reentrancy support. - -2002-05-15 Chris Johns <ccj@acm.org> - - * include/rtems/score/thread.h, inline/rtems/score/thread.inl, - src/threaddispatch.c, src/threadinitialize.c: - Move the C library re-enterrant support directly into - the thread dispatch code. RTEMS needs libc and so requiring - libc to use a user extension with its overhead is not the best - solution. This patch lowers the overhead to 2 pointer moves. - -2002-05-03 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * include/Makefile.am: Work-around to autoconf-2.53 adding PACKAGE_* - to autoheaders - sed out *PACKAGE* from cpuopts-tmp.h. - -2001-05-14 Till Straumann <strauman@slac.stanford.edu> - - * src/threaddispatch.c, src/threadhandler.c: Per PR211 fix - saving/restoring floating point context. The fpsave and fprestore - routines are only used in a executing context which _is_ fp and hence - has the FPU enabled. The current behavior required the FPU always to - be on which is very dangerous if lazy context switching is used. - [Joel Note: Some ports explicitly enabled the FPU in the FP save and - restore routines to avoid this.] - - The patch also makes sure (on powerpc only) that the FPU is disabled - for integer tasks. Note that this is crucial if deferred fp context - switching is used. Otherwise, fp context corruption may go undetected! - Also note that even tasks which merely push/pop FP registers to/from - the stack without modifying them still MUST be FP tasks - otherwise - (if lazy FP context switching is used), FP register corruption (of - other, FP, tasks may occur)! - - Furthermore, (on PPC) by default, lazy FP context save/restore - is _disabled_. - -2001-04-26 Joel Sherrill <joel@OARcorp.com> - - * src/objectcomparenamestring.c: Fix typos. - -2001-04-26 Joel Sherrill <joel@OARcorp.com> - - * include/rtems/score/object.h, inline/rtems/score/object.inl, - src/objectcomparenamestring.c: Address PR81 that - reworked POSIX message queues to add a descriptor separate from - the underlying message queue. This allows non-blocking to follow - the "open" not the underlying queue. As part of debugging this - it became clear that _Objects_Compare_name_string was broken - and a simple version using strncmp() was substituted. - -2002-04-18 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * include/rtems/system.h: Remove targopts.h. - -2002-04-17 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * include/rtems/system.h: Add the sparc to the target supporting - multlibs. - -2002-04-16 Chris Johns <ccj@acm.org> - - * src/threadinitialize.c: Per PR181, clear the array of user extension - pointers.

This was reported by Chris Johns <ccj@acm.org> - who also noticed that the use of switches for all disciplines - generated less efficient code than using explicit tests for the one - or two cases we were really interested in. Further review of his - modifications made it apparent that the "isa" methods to test mutex - discipline were not being used so this modification was swept into - the code as well. - -2001-08-30 Joel Sherrill <joel@OARcorp.com> - - * src/coremutexseize.c: Add missing code for proper handling - of nesting acquisitions.
