PCI Interrupt Routing is mapped using Interrupt Queue Agents IRQAGENT[0:3] and aggregating the INT[A:D] interrupts for each PCI-mapped device in the SoC. PCI based interrupts PIRQ[A:H] are then available for consumption by either the 8259 PICs or the IO-APIC, depending on the configuration of the 8 PIRQx Routing Control Registers PIRQ[A:H]. More information about can be find in Intel Quark X1000 datasheet[1] section 21.11. [1] - http://www.intel.com/content/www/us/en/embedded/products/quark/quark-x1000-datasheet.html |
