[rtl] IRQ on RTLinux or in Modules ?



Hello everybody,

I am a newbye in the hardware programming under Linux. I am porting an interrupt controlled software from DOS to Linux.

In this soft there are three IRQs which control three corresponding handlers.
I saw that it exists in the Rubini's books the modularization in the kernel space and that another way is represented by RTLinux.
As I have not yet a great knowledge in this area I am not able to choose the right method. I got the RT man and docs but for IRQ handling there are not great infos.  
My only pb deals with interrupts handling. I should prefer handle them if possible in the user space. Do you think that RTLinux is a easier way than the kernel space programming ?

I thank you in advance. 
Didier.
