Abstract
In an embodiment, a processor for performance state adjustment includes a plurality of processing engines (PEs), a power control unit, and an input/output memory management unit (IOMMU). The IOMMU is to determine a destination PE for a user interrupt based on mapping data of the IOMMU, and to send a notification of the user interrupt to the power control unit. The notification indicates the destination PE for the user interrupt. The power control unit is to adjust a performance state of the destination PE in response to the notification of the user interrupt. Other embodiments are described and claimed.
