Test of the Preemptive Kernel Patch

e8johan writes "Linux was originally written as a general-purpose operating system without any consideration for real-time applications. Recently Linux has become attractive to the real-time community due to its low cost and open standards. In order to make it more practical for the real-time community, patches have been written to affect such things as interrupt latency and context switch. These patches are public domain and are becoming part of the main Linux tree. The test results can be found here."

Preemptive *is* general purpose

[aminorex]

It takes the preemptive and low-latency patches
to make the linux kernel suitable for general-
purpose use on low-powered hardware. If you want
to watch smooth mpeg decodes while running a POVRay
job and serving web pages out of a database,
it takes a top-end current box to keep you happy,
unless you have preemptive and low-latency patches
applied.

Multimedia *is* realtime, so general-purpose implies
realtime.
