It provides a major performance boost for SMP configurations, see https://devel.rtems.org/ticket/2271 and https://devel.rtems.org/ticket/2273. It was tested on the Altera Cyclone V, ESA/Gaisler NGMP and Freescale T4240 platforms using the standard RTEMS testsuite, a randomized test case that covers the thread queue and watchdog implementation (it run several days) and with heavy load network traffic using the new network stack (it uses hundreds of locks). After two years of work all tests pass now on the NGMP platform in uni-processor and SMP configurations. The BSPs compile and link the samples using the latest RSB based tool chain (except targets with a broken compiler, e.g. AVR, Moxie). With this patch set the SMP support of RTEMS can be considered to be practically useful on targets with more than two processors. This is definitely not the case for the current Git master (possible RTEMS 4.11). Also timestamps are broken on SMP in the current Git master. So it may make sense to include this patch set in the RTEMS 4.11 release. We don't have additional RTEMS work in the next three months planned so this is the last big change set for a while. This work was sponsored by the European Space Agency (ESA). _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
