Systems, apparatuses, and methods for accessing and managing memories are disclosed herein. In one embodiment, a system includes at least first and second processors and first and second memories. The first processor maintains a request log with entries identifying requests that have been made to pages stored in the second memory. The first processor generates an indication for the second processor to process the request log when the number of entries in the request log reaches a programmable threshold. The second processor dynamically adjusts the programmable threshold based on one or more first conditions. The second processor also processes the request log responsive to detecting the indication. Additionally, the second processor determines whether to migrate pages from the second memory to the first memory based on one or more second conditions.

Systems and methods for accessing and managing a computing system memory

A device, method and software for handling multiple interrupts in a peripheral device are disclosed. The disclosed method includes, upon a hardware event in the peripheral device recording the hardware event and determining an acceptable period before which an interrupt should be generated to service the event. A timer at the peripheral device is adjusted as needed to maintain a value within the acceptable period. Upon expiry of the timer a single interrupt is generated to a processor interconnected to the peripheral device. In response to the single interrupt, software code is executed on the processor to service un-serviced hardware events for which an indicator has been recorded.
