PinOS: A Programmable Framework for Whole-System Dynamic Instrumentation
http://www.eecs.harvard.edu/~prash/pape ··· aper.pdf
PinOS is an extension of the Pin dynamic instrumentation framework for whole-system instrumentation, i.e., to instrument both kernel and user-level code. It achieves this by interposing between the subject system and hardware using virtualization techniques. Specifically, PinOS is built on top of the Xen virtual machine monitor with Intel VT technology to allow instrumentation of unmodified OSes.
PinOS is based on software dynamic translation and hence can perform pervasive fine-grain instrumentation. By inheriting the powerful instrumentation API from Pin, plus introducing some new API for system-level instrumentation, PinOS can be used to write system-wide instrumentation tools for tasks like program analysis and architectural studies. As of today, PinOS can boot Linux on IA-32 in uniprocessor mode, and can instrument complex applications such as database and web servers.
I was senseless and ignorant; I was a brute beast before you.
Yet I am always with you; you hold me by my right hand.
You guide me with your counsel, and afterward you will take me into glory.
Whom have I in heaven but you?
I only have you in my life
