AMD-V: AMD64 virtualization extension

Date and Time

Wednesday, November 18, 2009 from 6:30 pm to 9:00 pm

Location

MIT Building E-51, Room 325

Presenters

Summary

Shankar discusses AMD's hardware virtualization

Abstract

Shankar Viswanathan will describe the details of the hardware virtualization features implemented in AMD64 processors. Named AMD-V (formerly codenamed "Pacifica"), these architecture extensions greatly reduce the overhead involved in running multiple guest operating systems on top of the Virtual Machine Monitor (VMM). Shankar will discuss how AMD-V handles tasks such as saving and restoring OS state, how memory and paging is handled and give a brief overview of how IO peripherals are virtualized. A rough knowledge of the x86 architecture is beneficial, but not a prerequisite for this talk.

Bio

Shankar Viswanathan is a chip architect at AMD and currently works on the performance architecture for AMD semi-custom APUs. He has worked on the design and verification of several generations of AMD processors, most recently on the APUs used in the various XBox One and PS4 variants. He also spent a year at a software startup developing a thin hypervisor for run-time malware detection.
