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 |
