Not able to see the Interrupt from HOST:TMS320C6412

I am using TMS320C6412. We are using the PCI DSP driver code from valley technology as base to develop our DSP firmware. Currently we are evaluating valley tech. PCI DSP firmware. We found that even though we are setting HOSTSW interrupt from HOST we don't see interrupt getting handled in the DSP code.

Any pointers on what might be going wrong? Or please let us know the required steps for the host->dsp interrupt.

Thanks,

yatin,
I think the code will need to:
--enable the appropriate interrupt
--enable global interrupts
--configure the interrupt source
--include a interrupt handler for the desired interrupt
--set the appropriate vector in the interrupt table to point to the interrupt
handler
--The interrupt handler needs to clear the appropriate interrupt flag
--re-enable the appropriate interrupt.

I do not know how much of the above is already handled by the code.
