PCI Bus Interface Parameters

These parameters allow you to modify PCI interface features to gain better PCI performance for a given application.

TABLE 4-9PCI Bus Interface Parameters

ParameterDescription

tx-dma-weightDetermine the multiplication factor for granting credit to the TX side during a weighted round robin arbitration. Values are 0 to 3. (Default=0) Zero means no extra weighting. The other values are power of 2 extra weighting, on that traffic. For example of tx-dma-weight = 0 and rx-dma-weight = 3 then as long as RX traffic is continuously arriving its priority will be 8 times greater than TX to access the PCI

rx-dma-weightDetermine the multiplication factor for granting credit to the RX side during a weighted round robin arbitration. Values are 0 to 3. (Default=0)

infinite-burstAllows the infinite burst capability to be utilized. When this is in effect and the system supports infinite burst, the adapter will not free the bus until complete packets are transferred across the bus. Values are 0 or 1. (Default=0)

disable-64bitSwitches off 64 bit capability of the adapter. In some cases, it is useful to switch off this feature.

Values are 0 or 1. (Default=0, which enables 64 bit capability)
