To generate Software Interrupt to ARM920T processor
 

Hello all,

I am trying to generate SWI - SoftWare Interrupt - to ARM920T processor.I am using linux2.6.14 and arm tool chain for compilation.

Uptil now I have tried following things to implement above-mentioned thing.

- I have one unsigned long variable "swi_no" and this variable contains swi number, which is generated dynamically. So through this swi number, I can generate swi interrupt.

I have used following asm statements to implement this thing.

1)
__asm__ __volatile("MOVS r0,%0" : :"r"(swi_no));
__asm__ __volatile("SWI r0");

I have also tried following one

2)
__asm__ __volatile("SWI %0" : :"r"(swi_no) );

BUT BOTH GIVES SAME ERROR AS

ERROR:can't rellocate swi

Here ,i think some other assemblly statement can also be possible, but i dont know wht is tht...

SO ANYBODY CAN PLEASE SUGGEST
1) SOME WAY OUT OF MY ERROR
OR
2) SOME OTHER ASSEMBLY STATEMENT TO IMPLEMENT ABOVE MENTIONED THING.

Thank you.
