| |
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:
http://home.t-online.de/home/Bernhard_Kuhn/rtirq/20040304/rtirq-2.6.2-20040304.tar.bz2
Comments are highly appreciated!
best regards
Bernhard Kuhn
