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. + * src/bdbuf.c: Modified as part of above. 2002-07-01 Ralf Corsepius <corsepiu@faw.uni-ulm.de> * configure.ac: Remove RTEMS_PROJECT_ROOT. |
