RT Patch for Celleb - Patch Status and Performance Measurements

Tsutomu OWA

The Realtime-preempt patch, created and maintained by Ingo Molnar and others, is getting more and more popular in the Linux community. The patch has been ported to many architectures including PowerPC64, to which the Celleb platform, we have ported the RT patch on, belongs. While RT benchmarks shown by Steven Rostedt and Darren V. Hart at OLS 2007 and some other measurements exist for the Intel architecture, there seem to be less for the PowerPC architecture, especially on the recent kernel and RT patch. We will show the test results based on the same metrics with Darren V. Hart in this presentation as well as the Celleb specific techniques to improve latencies on the latest kernel and RT patch.
