Intel(R) 80219 General Purpose PCI Processor Evaluation Platform ...

External RAID Section 4The IQ80219 provides the capability for the user to develop RAID applications. There is arequirement to provide the ability of making the secondary PCI-X devices private and the ability toroute the interrupt lines. The following requirements describe this capability.4.1 Private Device ConfigurationThe devices on the SPCI-X bus (Expansion Slot and Intel ® 82544 Gigabit Ethernet Controller) areconfigured as private devices based on Table 86 requirements.Table 86.Private Device Configuration RequirementsDescriptionThe Secondary PCI-X Expansion slot is configured as private by either the 80219 (Using a GPIO pin) or IBMPCI-X Bridge.The Intel ® 82544 Gigabit Ethernet Controller is configured as private by either the 80219 (Using a GPIO pin) orIBM PCI-X Bridge.The device configuration scheme is based on Figure 17.Figure 17.IDSEL Routing for Private Device ConfigurationIntel ® 80219General PurposePCI ProcessorGPIO IDSEL_EN_PCIX1GPIO IDSEL_EN_GBEDipSwitchS7E1SPCI-X SlotPCIX_IDSELIDSELU3D1U3D1Dip SwitchS4D1GBE_IDSELS-Ad Line 28S-Ad Line 22Private SpaceS-Ad Line 20PCI-XBridgeS-Ad Line 18S-Ad Line 24Public SpaceIDSEL_REROUTE_ENDip SwitchS8E1-7Intel ® 80219General PurposePCI ProcessorGigabit EthernetB2837-01Board Manual 69
