We are workin using a freescale board, that has a powerpc procesor. We have connected a c6657 TI DSP at PICE express slot. We have a confict with the interrupt that is driven by PCI , because is used by other peripheral. It is impossible to change the design  to driven the second peripheral to an other interrupt.

We try to set  an other legacy interrupt in DSP side but the registers are read only . All the legacy interrupts use the same IRQ number. Is any function thast we can use to set another legacy interrupt in the of power pc?

We use the 3.12.13 kernel.


Best regards
