| Rteval is a python program written to evaluate the performance of a |
| realtime Linux kernel on a particular hardware platform. The program |
| unpacks source code for two loads: hackbench and a Linux kernel |
| compile, then loops running hackbench and a parallel build of the |
| Linux kernel. While the loads are running, the cyclictest program is |
| run to measure realtime performance under load. When the specified run |
| duration is met, the loads are stopped and cyclictest outputs measured |
| timer latency values in histogram format, which is analyzed by |
| rteval. Rteval then writes an XML file to disk with information about |
| the system (gotten through DMI tables), the raw histogram data |
| collected during the run and the statistical analysis of the run. |
| |
| The rteval source may be pulled from it's git tree on kernel.org: |
