[ixp1200] How to signal from Pentium to IXP EB?

[조준우]

Hello.

I use IXP1200 EB attached(on PCI slot) to Pentium PC.

How can I signal from Pentium PC to MICROENGINE in IXP EB?

I searched VERA code to find the method. But I failed to find until now.


Is there a good method? Like using some register or using interrupt?

I think "polling" method now. Namely, PC writes a flag into SDRAM or SRAM region
 
and MicroEngine check that flag continually.

But I think that interrupt is more polished method. ^^


Plz give me any method about signalling from PC to IXP EB.

Peformance is most important for my application.

Thanks!
