In one embodiment, a method is provided. The method of this embodiment provides determining if a management queue can be created, and if a management queue can be created, allocating virtually contiguous memory to a management queue associated with a device, registering the management queue, and creating a management queue context.

Managing system memory resident device management queues

The apparatus and method described herein are for enabling cacheable writes to I/O device registers. A cache monitor, which may be present in a controller hub, monitors accesses to cache lines in a microprocessor. The cache monitor also associates cache lines in the microprocessor with I/O device registers. When an access to certain cache lines are detected, the cache monitor is operable to receive the contents of the cache line and write those contents to an associated I/O device register. Therefore, a microprocessor may write to a cache line, instead of making an uncacheable write to the I/O device register directly.

I/O hub resident cache line monitor and device register update

An apparatus and method for reducing operating system interrupts by queuing incoming network traffic units received by a network interface, where said units are received without interrupting a host environment on receiving queued units. However, if a predetermined number of received units have a same origin, then the host environment is interrupted as subsequent network traffic units are received by the network interface, until a predetermined number of network traffic units are subsequently received from a different origin. Notwithstanding queuing incoming network traffic units, the host environment is interrupted on expiration of a timeout period, or if a predetermined number of units have been queued.
