fffae72b45 Fixed serial support in 2.6 (too much work for...)
Removed bootloader and just wrote command line into linux kernel

base/inifile.cc:
    the forked process should not return, it should exit.
dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
    The serial port in reality has some delay and linux expects it. This
    schedules an interrupt 300 cycles after the transmit instead of
    immediately
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:

a4d7bb113a Make a new stat type of Value which is a scalar stat that
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:

    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

    don't need everything to be extern.

    Make stuff work a tad bit better
test/stattest.cc:

24715f50ac add support for sticking generated files in the build directory

    and reimplement it as a visitor.

    move the text output code to base/stats/text.(cc|hh) and
    reimplement it as a visitor.

    move the database stuff into base/stats/statdb.(cc|hh) and
    get rid of the class.  Put everything as globals in the
    Statistics::Database namespace.

    allocate unique ids for all stats.

    directly implement the check routine and get rid of the
    various dumping routines since they're now in separate files.

    make sure that no two stats have the same name

    clean up some loops
base/statistics.hh:
    major changes to the statistics package again

    lots of code was factored out of statistics.hh into several
    separate files in base/stats/ (this will continue)

    There are now two Stat package types Result and Counter that
    are specified to allow the user to keep the counted type
    separate from the result type.  They are currently both doubles
    but that's an experiment.  There is no more per stat ability to
    set the type.  Statistics::Counter is not the same as Counter!

    Implement a visitor for statistics output so that new output
    types can be implemented independently from the stats package
    itself.

    Add a unique id to each stat so that it can be used to keep
    track of stats more simply.  This number can also be used in
    debugging problems with stats.

    Tweak the bucket size stuff a bit to make it work better.

    fixed VectorDist size bug
cpu/memtest/memtest.cc:
    Fix up for changes in stats package
    Don't use value() since it doesn't work with binning.  If you
    want a number as a stat, and to use it in the program itself,
    you really want two separate variables, one that's a stat,
    and one that's not.

f3861d0cc7 Overall gist of this is to 'dynamicize' the tracking of functions so you can choose them at the .ini stage rather than at compile time.
to do it:
in .ini file set binned_fns=foo null bar foo

what this says is, track foo when it is called by null (i.e. anything).  bin bar only when it is called by foo.
essentially, if you have a path of functions to track, the 0th, 2nd, 4th fn listed are the fns to track, and the 1st, 3rd, 5th are their respective callers.

base/statistics.hh:
    turn it back to FS_MEASURE since we already have a build in place

    remove FS_MEASURE #defs.  add more DPRINTF's.  manage an anomaly that happens when tracking idle_thread.
kern/tru64/tru64_events.hh:

kern/tru64/tru64_system.cc:
    make DumpState print all the time, but only with DPRINTF.  add a new parameter to tru64System a vector<string> binned_fns, to read in from .ini file.  now all this binning stuff is dynamically generated.

    remove all static binning stuff, add support for dynamic
sim/system.cc:
    change nonPath bin name to Kernel, remove FS_MEASURE

    - Deal properly with single-segment ELF executables (e.g. kernels)...
    haven't tested this but it looks like it matches the functionality
    of the patch the L4::Pistachio guys sent.

    - Factor load symbol code into one common function.

    - Some formatting to match style conventions.

    - Only include libelf stuff in .cc file, not .hh.

7e07aa9300 Fix cprintf bug, plus minor cleanup & better error messages.
base/cprintf.cc:
    Fix bug where a call with a format string with no specifiers
    but one or more arguments would crash.  Old code tried to print
    extra args using last available format, but in this case there
    was no format, hence the problem.  Now we just print "<extra arg>"
    for each extra arg.

    Also reorganized code a bit to make scope of fmt variable
    match the scope in which you can be confident it's meaningful.

base/statistics.cc:
base/statistics.hh:
    -  add python output support to the statistics package
    -  each statistic type has a python() member function that takes
    a Python object to which the stat will output it's python
    representation
    -  add getStatData hack so that the StatData pointer can be looked
    up by the proxies with their opaque pointer to the stat they're
    proxying for.  This is necessary because the proxy really proxies
    for the bin and not the stat.  Be nice to figure out how to get
    rid of it.  The hack is used so that the str() function of a
    proxy can properly name itself.
    -  To print formula stats, every stat has a str() function that
    converts that stat to a string that python can execute to get
    a value.

368de4109f Sweeping change in the stats package....again...
base/statistics.cc:
    -  Merge the m5 display and simplescalar compatible display functions.
    -  Use functors for the stats printing instead of functions.  This
    gets rid of the very long argument lists and improves clarity.
    -  Fix a bug in binning that caused an invalid allocation to occur.
base/statistics.hh:
    -  Instead of using a compile time variable to choose whether
    to print in ss compat mode, we use a runtime variable.
    This is how we'll choose python output.
    -  There are no more virtual functions in the statistics themselves.
    All virtual functions have been moved into a secondary helper class.
    Every stat has an associated helper class that knows how to access
    certain variables in that stat.
    There is a hash_map from the stat to it's helper class data.  This was
    done because the helper data is only used during setup, stats reset,
    and printing.  All of which happen rarely, and you want to avoid
    any performance hit that you can.
    -  To provide the name(), desc(), etc functions to classes so that the
    user can set various parameters to the stats class, a single class
    containing all of those functions was created.  An odd trick was
    done to actually make this class derive from the stat class because
    a base class with no data actually does end up taking up space.
    -  The detail namespace was removed for now.  I'll put it back when the
    package is not in so much flux.
    -  Standard deviation, and mean were added to all distribution stats.
    -  There are several bugfixes and changes that aren't mentioned
test/Makefile:
    Don't test sim_stats foo.
test/stattest.cc:
    Don't test sim_stats foo.
    Fix bin usage so that it corresponds to the current usage.

7976794aad Restructuring of LiveProcess etc. to support multiple emulated OS syscall
interfaces, and specific support for Alpha Linux.  Split syscall emulation
functions into several groups, based on whether they depend on the specific
OS and/or architecture (and all combinations of above), including the use of
template functions to support syscalls with slightly different constants
or interface structs.

arch/alpha/alpha_tru64_process.cc:
    Incorporate full Tru64 object definition here, including structure and constant definitions.
    This way we can wrap all of the functions inside the object, and not worry about namespace
    conflicts because no one outside this file will ever see it.

    prog.hh is now process.hh
    move architecture-specific syscall arg accessors into ExecContext
cpu/simple_cpu/simple_cpu.cc:
    No need to include prog.hh (which has been renamed)
sim/process.cc:
sim/process.hh:
    LiveProcess is now effectively an abstract base class.
    New LiveProcess::create() function takes an object file and dynamically picks the
    appropriate subclass of LiveProcess to handle the syscall interface that file expects
    (currently Tru64 or Linux).

07d56ae7be better binning of Average stats
base/statistics.hh:
    Try to make binning of Average statistics work a little better.
    This solution is far from perfect though since we really need
    to call set(p.current, p) when the binning takes place.

    To fix the binning, we need to have the current value non-binned,
    to do that, we make make the current value part of the Params struct.
    This means that we can't pass around const Params structs

    Maybe we need a binswap callback :/
