Decrementer interrupt in linux project

[pabloramos]

Hi everyone,

I would like to know if it is possible to have decrementer interrupt in a Multicore Linux Project.
I have tried to use the interrupt like a bareboard Project  and it compiles but at the debug time it remains blocked.
Does anyone have  perform interrupts in Linux multicore projects? How to do that?

Thanks in advanced.

If the question is specifically about Linux, the kernel does use Decrementer.

It registers Decrementer as a standard clock event device. Related code can be found in

arch/powerpc/kernel/time.c, arch/powerpc/kernel/head_fsl_booke.S and

arch/powerpc/kernel/head_booke.h.

More information on clock event device and related concepts can be found in

Documentation/timers/highres.txt

What do you mean by "at the debug time it remains blocked"? Did you find "TSR[DIS]" setted but PC not jumppting into handler?
