This page is an archive of old M5 documentation predating the GEMS merger and subsequent gem5 renaming. See the Documentation page for the current documentation.
Complementary information from our tutorials, including about three hours of video from our last tutorial, is available here. The tutorials provide basic information about using M5 and are time well spent for anyone new to the simulator.
