x86-MMU-Profiler

This is a user-space tool that profiles all running applications under a specified user, and periodically outputs their MMU Overhead i.e., the fraction of CPU Cycles spent in servicing TLB misses. This tool was used to assist our research system HawkEye (published in ASPLOS'19) to achieve fair huge page allocation across multiple applications.
