Understanding Modern Device DriversAsim Kadav and Michael M. SwiftComputer Sciences Department, University of Wisconsin-Madison{kadav, Drivers are the single largest contributor to operating-systemkernel code with over 5 million lines of code in the linux kernel ,and cause significant complexity, bugs and development costs. Re-cent years have seen a flurry of research aimed at improving the re-liability and simplifying the development of Drivers . However, littleis known about what constitutes this huge body of code beyond thesmall set of Drivers used for this paper, we study the source code of linux Drivers to un-derstand what Drivers actually do, how current research applies tothem and what opportunities exist for future research.}
