Well Jan, with respect to PIC(i8259) I don't see many changes as compared to code in Linux-2.6 on X86. But timer and whole Interrupt system changes. Will look closely in it. Have to put more effort on System calls as Phillipe said, Will look into it and have to write test code with other customozed domain like Registering with timer interrupt and try passing it to Linux after handling it.

As you already picked a fairly new I-pipe core (1.5), the differences will be around the kernel subsystems that changed meanwhile. Philippe may better comment on details, still I guess no one here has tracked the MIPS development to be aware of important changes there. Aspects to check are specifically the timer and the IRQ subsystems. Both are under heavy reconstruction recently, heading toward more generic implementation which is a Good Thing also for I-pipe. When you upgrade, going to head (then likely 2.6.20) is recommended to avoid doing work twice - given that this kernel is stable in vanilla form for you. Jan
