PATCH 1/1 real-time interrupts for linux 2.6

Hi everybody!

I hope that i can steal enough of your precious time to get your attention for a patch that adds hard real time support to the linux kernel (worst case response time below 5 microseconds at a 100 KHz periodic interrupt).

The proposed "real time interrupt patch" enables the linux kernel for hard-real-time applications such as data aquisition and control loops by adding priorities to interrupts and spinlocks.

New festures since first release
--------------------------------

* ported to 2.6 (tested with 2.6.2 and 2.6.3)
* io-apic priority operation partly implemented
* enhanced example application
* performed benchmarks

The following document will describe the patch in detail and how to install it:

The patch and a demo application can be downloaded from:

Comments are highly appreciated!

best regards
