| |
At Monta Vista Software, we developed a tool that measures the maximum interrupt blocking times in standard Linux. The results can be used to estimate interrupt latencies, to detect timing problems, and etc. The purpose is to help adopt standard Linux into embedded real-time systems.
We tested the tool on a few systems. The resutls and the analysis can be found on the same web page.
All source code are open and GPLed. So are the results and analysis. :-)
Your feedbacks and contributions are always welcome.
