Abstract
An interrupt is identified from an input/output (I/O) device and an address of a particular cache line is identified associated with the interrupt. The cache line corresponds to a destination of the interrupt and represents one or more attributes of the interrupt. A request is sent to a coherency agent to acquire ownership of the particular cache line and a request is sent to perform a read-modify-write (RMW) operation on the cache line based on the interrupt.
