title: Intel IXP4xx XScale Networking Processors Interrupt Controller

description: |

  This interrupt controller is found in the Intel IXP4xx processors.

  Some processors have 32 interrupts, some have up to 64 interrupts.

  The exact number of interrupts is determined from the compatible

  string.



  The distinct IXP4xx families with different interrupt controller

  variations are IXP42x, IXP43x, IXP45x and IXP46x. Those four

  families were the only ones to reach the developer and consumer

  market.
