IQ : a whole-system instrumentation framework for post analysis Xu, Wenhao


Analyzing operating systems is a hard problem. Instrumentation can be used to insert analysis code into executions of an operating system. IQ is a dynamic instrumentation framework for instrumenting the whole system. It records executions of an operating system running in a virtual machine and decouples analysis from executions of the operating system. IQ tools can do heavyweight analysis during replays of executions and refine the analysis through continuous replay of the same execution. IQ is a fine granularity framework that provides an API appropriate to instrument operating systems. To our best knowledge, IQ is the first post-analysis framework for instrumenting the whole system.
