Analysis of the Linux RT Patch

Background

The Linux Kernel provides basic real-time capabilities as defined in the POSIX standard. However, a standard desktop operating system can not guarantee short latencies. This is where the RT Patch comes into play. It introduces many tweaks into the Kernel source code to optimize the real-time behavior. Some of these changes are already included in the standard Kernel because they are of benefit for the average user.

In the course of this assingment, the different changes in relation to real-time behavior should be described and evaluated. Therefore, the patch must be applied to the Linux Kernel and different combinations options should be realized. The effect of these options should be measured with appropriate benchmarks.
