Reconstructing I/O
Keir Fraser, Steven J. Hand, Rolf Neugebauer, Ian A. Pratt, Andrew Warfield, Mark Williamson · 2004
We present a next-generation architecture that addresses problems of dependability, maintainability, and manageability of I/O devices and their software drivers on the PC platform. Our architecture resolves both hardware and software issues, exploiting emerging hardware features to improve device safety. Our high-performance implementation, based on the Xen virtual machine monitor, provides an immediate transition opportunity for today’s systems.
