The ATE (Address Translation Entry for 32bit PCI mappings) Attribute bits are different for our PIC Bridge ASIC and our TIOCP Bridge ASIC. On our PIC Bridge ASIC bit#1 is the `Coherent Translation' attribute, but on our TIOCP Bridge ASIC bit#1 is the `PIO' attribute -mike - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
