This is release m5_1.1 of the M5 simulator.

WHAT'S INCLUDED (AND NOT)
-------------------------
Since you're reading this file, presumably you've managed to untar the
distribution. The archive you've unpacked has three subdirectories:
The basic source release includes these subdirectories:
- m5: the simulator itself
- m5-test: regression tests and scripts to run them
- m5-test: regression tests
- ext: less-common external packages needed to build m5
- alpha-system: source for Alpha console and PALcode
M5 is a capable, full-system simulator that current supports both Linux
2.4/2.6 and the proprietary Compaq/HP Tru64 version of Unix. We are able
to distribute Linux bootdisks, but we are unable to distribute bootable
disk images of Tru64 Unix. If you have a Tru64 license and are interested
in obtaining disk images, contact us at m5-dev@eecs.umich.edu.
To run full-system simulations, you will need compiled console,
PALcode, and kernel binaries and one or more disk images. These files
are collected in a separate archive, m5_system_1.1.tar.bz2. This file
is included on the CD release, or you can download it separately from
Sourceforge.
M5 supports Linux 2.4/2.6, FreeBSD, and the proprietary Compaq/HP
Tru64 version of Unix. We are able to distribute Linux and FreeBSD
bootdisks, but we are unable to distribute bootable disk images of

obtaining disk images, contact us at m5-dev@eecs.umich.edu.
The CD release includes a few extra goodies, such as a tar file
containing doxygen-generated HTML documentation (html-docs.tar.gz), a
set of Linux source patches (linux_m5-2.6.8.1.diff), and the scons
program needed to build M5. If you do not have the CD, the same HTML
documentation is available online at http://m5.eecs.umich.edu/docs,
the Linux source patches are available at
http://m5.eecs.umich.edu/dist/linux_m5-2.6.8.1.diff, and the scons
program is available from http://www.scons.org.

choose by copying the SConstruct file there and creating symbolic links
