Filtering and remapping interrupts

In one embodiment, an input/output memory management unit (IOMMU) comprises a control register and control logic coupled to the control register. The control register is configured to store a base address of a device table, wherein a given input/output (I/O) device has an associated device identifier that selects a first entry in the device table. The first entry comprises a pointer to an interrupt remapping table. The control logic is configured to remap an interrupt specified by an interrupt request received by the IOMMU from the given I/O device if the interrupt remapping table includes an entry for the interrupt.
