My application is running on desktop Linux. I would like to add more reliability and make it faster(Soft real time) on my embedded Linux porting without making many changes to the application.
I have read few things about preemptible kernel patch, which sounds ideal solution for some soft real time application like mine.
RTAI, Rtlinux certainly is not good for me as i have to make changes in the application.
I am running on 2.4 right now, 2.6 seems to have some good support for soft real time applications.
I am not sure how exactly i can apply preemptible kernel patch. What changes do i have to make in the application to run with preemptible kernel patch.
And very important , how do I compare it with original system after applying the patch , and get nice interrupt latency and jitter characteristic :)
Can any one help ???
