Intel® Server Board SE7501WV2 TPS

Configuration and Initialization

4.11.1Legacy Interrupt Routing

For PC-compatible mode, the ICH3-S provides two 82C59-compatible interrupt controllers. The two controllers are cascaded with interrupt levels 8-15 entering on level 2 of the primary interrupt controller (standard PC configuration). A single interrupt signal is presented to the processors, to which only one processor will respond for servicing.

4.11.1.1Legacy Interrupt Sources

The following table recommends the logical interrupt mapping of interrupt sources on the SE7501WV2 server board. The actual interrupt map is defined using configuration registers in the ICH3-S.

4.11.2Serialized IRQ Support

The SE7501WV2 server board supports a serialized interrupt delivery mechanism. Serialized IRQs (SERIRQ) consist of a start frame, a minimum of 17 IRQ / data channels, and a stop frame. Any slave device in the quiet mode may initiate the start frame. While in the continuous mode, the start frame is initiated by the host controller.

4.11.3APIC Interrupt Routing

For APIC mode, the SE7501WV2 server board interrupt architecture incorporates three Intel® APIC devices to manage and broadcast interrupts to local APICs in each processor. One of the APICs is located in the ICH3-S and the other two APICs are in the P64H2 (one for each PCI
