Abstract: Methods and apparatus for providing page migration of pages among tiered memories identify frequently accessed memory pages in each memory tier and generate page hotness ranking information indicating how frequently memory pages are being accessed. Methods and apparatus provide the page hotness ranking information to an operating system or hypervisor depending on which is used in the system, the operating system or hypervisor issues a page move command to a hardware data mover, based on the page hotness ranking information and the hardware data mover moves a memory page to a different memory tier in response to the page move command from the operating system.

Abstract: A system and method for finding the sources of increased interrupt latencies. An interrupt controller includes monitoring logic for measuring and storing latencies for servicing interrupt requests. The interrupt controller determines a measured latency is greater than an associated threshold and in response sends an indication of a long latency. The interrupt controller may send the indication to firmware, a device driver, or other software. The interrupt controller stores associated information with the measured latency for debug purposes. Additionally, the monitoring logic may perform statistical analysis in place of, or in addition to, software.
