2 Hawk PCI Host Bridge & Multi-Processor Interrupt Controller will be four cache lines. This field is only applicable if read-ahead has been enabled. The encoding of this field is shown in the table above. WXFTx Write Any FIFO Threshold. This field is used by the PHB to determine a FIFO threshold at which to start writing data into local memory during any PCI write transaction. Once the threshold is exceeded and the write has begun, the PHB will continue to empty its FIFO until it can no longer create a cache line. This field is only applicable if write-posting has been enabled. The encoding of this field is shown in the above table. The PCI Slave Offset Registers (PSOFFx) contain offset information associated with the mapping of PCI memory space to PPC memory space. The field within the PSOFFx registers is defined as follows: PSOFFx PCI Slave Offset. This register contains a 16-bit offset that is added to the upper 16 bits of the PCI address to determine the PPC address used for transfers from PCI to the PPC bus. This offset allows PPC resources to reside at addresses that would not normally be visible from PCI. CONFIG_ADDRESS Register WXFT Write FIFO Threshold 00 4 Cache lines 01 3 Cache lines 10 2 Cache lines 11 1 Cache lines The description of the CONFIG_ADDRESS register is presented in three perspectives: from the PCI bus, from the PPC bus in big-endian mode, and from the PPC bus in little-endian mode. Note that the view from the PCI bus is purely conceptual, since there is no way to access the CONFIG_ADDRESS register from the PCI bus. 2-106 <strong>Computer</strong> Group Literature Center Web Site
