For example, 'scons ALPHA_SE/test/opt/quick' will build
ALPHA_SE/m5.opt if necessary and run all the self-identified
"quick" tests on it. Other possibilities:
- Run just test1: scons ALPHA_SE/test/opt/test1
- Run all tests: scons ALPHA_SE/test/opt
- Run all tests on debug build: scons ALPHA_SE/test/debug
- Update test1 reference outputs in m5-test:
scons update_ref=y ALPHA_SE/test/opt/test1
The proper tests will be selected based on the setting
of FULL_SYSTEM, ALPHA_TLASER, etc.
README:
Update directions to use scons-based test invocation.
SConscript:
Return list of generated build environments to SConstruct
so it can associate tests with each of them.
Set 'M5Binary' attribute on each env to record name of
generated binary to be tested.
build/SConstruct:
- Support invoking m5-test tests via scons.
- Add new non-sticky option category, for 'update_ref'.
- Move existing "sticky" option definitions out of
build_dir loop. Someday we can generate help text
from these.
- Make 'CC' and 'CXX' sticky options; use environment vars as
defaults if available.
- Make config builder more scons-y.
python/m5/__init__.py:
Make AddToPath() correctly handle relative path arguments.
Assumes that sys.path[0] has the directory where the current
Python file lives; new m5execfile() function sets this up
properly for exec'd files.

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:
|
|
|
|
cd $top/m5/build
|
|
scons ALPHA_SE/test/opt/quick
|
|
|
|
To build and test the full-system simualator:
|
|
|
|
1. Download the full-system binary package from
|
|
http://m5.eecs.umich.edu/dist/m5_system_1.1.tar.bz2. 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/opt/test/quick".
