发明名称 METHOD TO ACCELERATE MESSAGE SIGNALED INTERRUPT PROCESSING
摘要 Methods to accelerate a message signaled interrupt (MSI) are described herein. An embodiment of the invention includes an interrupt controller to receive a messaged signaled interrupt (MSI) request from a device over a bus, and an execution unit coupled to the interrupt controller to execute an interrupt service routine (ISR) associated with the device, the execution unit to retrieve interrupt data from a predetermined memory location specifically allocated to the device and to service the MSI using the interrupt data, without having to obtain the device interrupt data via an input output (IO) transaction.
