proxies for a real C/C++ scalar value or scalar functor.
This replaces the scalar() and functor() terms that were
previously used in formulas. This helps when dumping
statistics because the formulas are not supposed to change.
cpu/base_cpu.cc:
Add a number of cycles stat to the cpu object that tracks the
number of cycles that the cpu has executed. This starts to pave
the way for cpu cycles being different from event ticks.
cpu/base_cpu.hh:
provide a functor for calculating all simulated instructions
of all CPUs and a virtual function for determining that number.
To deal with the change from functor() to Value::functor()
cpu/simple_cpu/simple_cpu.cc:
simTicks -> numCycles
numInsts is now a real Scalar stat, not a Formula
cpu/simple_cpu/simple_cpu.hh:
numInsts is now a real Scalar stat, not a Formula
count all instructions
sim/stat_control.cc:
simInsts, simTicks, hostMemory, and hostSeconds are no
longer Statistics::Formula but rather Statistics::Value
add new stat for tick frequency
sim/stats.hh:
don't need everything to be extern.
test/Makefile:
Make stuff work a tad bit better
test/stattest.cc:
test out Statistics::Value

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 just "ply") Although M5 is capable of full-system simulation, the only OS it currently supports is the proprietary Compaq/HP Tru64 version of Unix. We are thus unable to distribute bootable disk images freely. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-dev@eecs.umich.edu. 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. cd $top/m5/setup ./setup ALPHA # set up build/ALPHA directory cd $top/m5/build/ALPHA make m5.opt # use "-j N" if you've got an MP system # wait for build... cd $top/m5-test ./do-tests.pl -B ALPHA # test what you just built # wait for tests to run... # should end with "finished do-tests successfully!" If you run into errors regarding m5/arch/alpha/decoder.cc, just "touch" that file to update its timestamp. This file is generated from a compact ISA description using a program written in Python. If you have Python 2.2.2 or later installed on your system, you should be able to generate it yourself, but if you don't have Python (or have an older version), you may run in to trouble. Since we've shipped a working copy of decoder.cc, it's not necessary to have Python to build M5 (unless you start modifying the ISA decription). Unfortunately, sometimes make gets confused and tries to do so anyway. The "touch" should convince make to stop trying.
