This is release m5_1.1 of the M5 simulator.
|
|
|
|
This file contains brief "getting started" information and release
|
|
notes. For more information, see http://m5.eecs.umich.edu. If you
|
|
have questions, please send mail to m5sim-users@lists.sourceforge.net.
|
|
|
|
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:
|
|
- m5: the simulator itself
|
|
- m5-test: regression tests and scripts to run them
|
|
- 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.
|
|
|
|
WHAT'S NEEDED
|
|
-------------
|
|
- GCC (version 3.3 or 3.4 recommended)
|
|
- Python 2.3 or newer
|
|
- SCons 0.96.1 (see http://www.scons.org)
|
|
|
|
WHAT'S RECOMMENDED
|
|
------------------
|
|
- MySQL (for statistics complex statistics storage/retrieval)
|
|
- Python-MysqlDB (for statistics analysis)
|
|
|
|
GETTING STARTED
|
|
---------------
|
|
|
|
There are two different build targets and three optimizations levels:
|
|
|
|
Target:
|
|
-------
|
|
ALPHA_SE - Syscall emulation simulation
|
|
ALPHA_FS - Full system simulation
|
|
|
|
Optimization:
|
|
-------------
|
|
m5.debug - debug version of the code with tracing and without optimization
|
|
m5.opt - optimized version of code with tracing
|
|
m5.fast - optimized version of the code without tracing and asserts
|
|
|
|
Different targets are built in different subdirectories of m5/build.
|
|
Binaries with the same target but different optimization levels share
|
|
the same directory. Note that you can build m5 in any directory you
|
|
choose by copying the SConstruct file there and creating symbolic links
|
|
to the 'm5' and 'ext' directories.
|
|
|
|
The following steps will build and test the simulator. The variable
|
|
"$top" refers to the top directory where you've unpacked the files,
|
|
i.e., the one containing the m5, m5-test, and ext directories. If you
|
|
have a multiprocessor system, you should give scons a "-j N" argument (like
|
|
make) to run N jobs in parallel.
|
|
|
|
To build and test the syscall-emulation simulator:
|
|
|
|
1. In $top/m5/build, run "scons ALPHA_SE/m5.opt".
|
|
2. In $top/m5-test, run "./do-tests.pl -B ALPHA_SE".
|
|
|
|
The tests should end with "finished do-tests successfully!"
|
|
Note: if you're running under Cygwin, several tests will fail with an
|
|
"EIO trace inconsistency: ICNT mismatch" error. This is due to the
|
|
lack of fesetround() under Cygwin causing differences in floating-point
|
|
rounding. Other than that discrepancy your simulator is working perfectly.
|
|
|
|
To build and test the full-system simualator:
|
|
|
|
1. Download the full-system binary package from XXX. This package includes
|
|
disk images and kernel, palcode, and console binaries for Linux and FreeBSD.
|
|
2. Edit SYSTEMDIR in $top/m5-test/SysPaths.py to point to your local copy
|
|
of the binaries.
|
|
3. In $top/m5/build, run "scons ALPHA_FS/m5.opt".
|
|
4. In $top/m5-test, run "./do-tests.pl -B ALPHA_FS".
