HARDWARE SUPPORTED MEMORY LOGGING

摘要

Logging changes to a physical memory region during a logging time interval includes: detecting a write operation to the physical memory region, wherein the write operation modifies an indirect representation that corresponds to a physical data line in the physical memory region; and recording log information associated with the write operation.

1. A system comprising:
a memory comprising a physical memory region to be logged; a first processor configured to execute instructions and access the memory; a second processor configured to:
detect a write operation made by the first processor to the physical memory region, wherein the write operation modifies an indirect representation that corresponds to a physical data line in the physical memory region; andrecord log information associated with the write operation.
