Ron Dreslinski d9317dd348 Some more useful debugging info for kernel panic and die events 
Increase the default number of CSHR's, we should really fix this or make it a parameter

Use a setBlocked call to tell the bus it should block

New technique for sampling and switchover:
1) Sampler switchover event happens
2) All cpus in the current phase of sampling associated with this sampler are signaled to switchover
3) Each cpu drains it's pipe of things being executed (stops fetching and waits for empty pipe)
4) Once the pipe is empty the cpu calls back to the sampler to signal it has finished, and moves into the switchedout state (continues not to fetch)
5) The sampler collects all the signals, once all cpus are drained it calls the new cpu's in the next phase to takeover from the correct cpu
6) The statistics are reset and the next switchover time is calculated from this point

README 

This is release m5_1.0_beta1 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
   (currently ply and libelf)

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(3.X)
-Python(2.2.2+)

WHAT'S RECOMMENDED
------------------
-MySQL (for statistics complex statistics storage/retrieval)
-Python-MysqlDB (for statistics analysis) 

GETTING STARTED
---------------

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.

There are three different build targets and three optimizations in each level:
Target:
-------
ALPHA  - Syscall emulation simulation
KERNEL - Linux full system simulation
KERNEL_TLASER - Tru64 Unix 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

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