3This file contains brief "getting started" information and release
4notes.  For more information, see http://m5.eecs.umich.edu.  If you

7WHAT'S INCLUDED (AND NOT)
8-------------------------

10Since you're reading this file, presumably you've managed to untar the
11distribution.  The archive you've unpacked has three subdirectories:
12 - m5: the simulator itself
13 - m5-test: regression tests and scripts to run them
14 - ext: less-common external packages needed to build m5
15   (currently ply and libelf)
16
17M5 is a capable, full-system simulator that current supports both Linux
182.4/2.6 and the proprietary Compaq/HP Tru64 version of Unix. We are able 
19to distribute Linux bootdisks, but we are unable to distribute bootable
20disk images of Tru64 Unix. If you have a Tru64 license and are interested 
21in obtaining disk images, contact us at m5-dev@eecs.umich.edu.

23WHAT'S NEEDED
24-------------
25-GCC(3.X)
26-Python(2.4+)
27
28WHAT'S RECOMMENDED
29------------------
30-MySQL (for statistics complex statistics storage/retrieval)
31-Python-MysqlDB (for statistics analysis) 
32
33GETTING STARTED
34---------------
35
36The following steps will build and test the simulator.  The variable
37"$top" refers to the top directory where you've unpacked the files,
38i.e., the one containing the m5, m5-test, and ext directories.
39
40There are three different build targets and three optimizations in each level:
41Target:
42-------
43ALPHA_SE - Syscall emulation simulation
44ALPHA_FS - Linux full system simulation
45ALPHA_FS_TL - Tru64 (Turbolaser) Unix full system simulation
46
47Optimization:
48-------------
49m5.debug - debug version of the code with tracing and without optimization
50m5.opt   - optimized version of code with tracing
51m5.fast  - optimized version of the code without tracing and asserts

53cd $top/m5/build
54scons TARGET/OPTLEVL  # e.g. ALPHA_FS/m5.opt, use -j N if you have a MP system
55cd $top/m5-test
56./do-tests.pl -B ALPHA_SE	# test what you just built
57./do-tests.pl -B ALPHA_FS	# test what you just built
58# wait for tests to run...
59# should end with "finished do-tests successfully!"
