ALPHA_FS finally compiles again

SConscript:
    Use a couple more FS sources, still don't compile that much

Ali Saidi e196d20d9d Make TranslatingPort be a type of Port rather than something special
arch/alpha/arguments.cc:
    rather than returning 0, put a panic in... it will actually make us fix
    this rather than scratching our respective heads

Steve Reinhardt b8a2d1e5c7 More progress toward compiling... partly by
fixing things, partly by ignoring CPU models
that don't currently compile.

SConscript:
    Split sources for fast, simple, and o3 CPU models into
    separate source lists.  For now none of these are included
    in the base source list, so you won't get any CPU models
    at all... but we still can't compile the other stuff so
    it's not an issue.

Steve Reinhardt 03a2aca9a9 Changes for Process object initialization in merged-memory environment.
System object now exists for both fullsys and syscall emulation, as the
latter needs it so that Process objects can find the shared PhysicalMemory
for initialization.
Changes are incomplete: still need to fix up Process (& EioProcess) memory
initialization and syscall emulation code for new mem interface.

cpu/exec_context.hh:

python/m5/objects/Process.py:
    Add System parameter to Process object (& subobjects).
python/m5/objects/System.py:
    Segregate full-system only Process parameters (most of them!).
sim/process.cc:
    Take System argument in constructor.
    Move initialization to startup() callback to occur after system & cpus
    are initialized.
    Generate ProxyMemory object to pass to loader for transparent
    virtual page allocation.
sim/process.hh:
    Take System argument in constructor.
    Move initialization to startup() callback to occur after system & cpus
    are initialized.
sim/system.cc:
sim/system.hh:
    Enable System object for non-full-system too.
    Basically involved putting most of the existing code
    inside '#ifdef FULL_SYSTEM'.
    Key thing needed for syscall emulation at this point is
    the PhysicalMemory object (for Process initialization).

of passing that in as a parameter.

cpu/base.cc:

    move init() code to startup() to ensure that all CPUs are registerd.
python/m5/objects/BaseCPU.py:

    that it will be generated.
sim/system.cc:
    allow the registerExecContext functioin to take a desired
    cpu_id as a parameter.  Check to ensure that the id isn't
    already used.  Accept -1 as a request to have an id assigned.

Nathan Binkert 9023f5c96d - Clean up and factor out all of the binning code into a
single place so it's easier to work with.
-  Add support for binning kernel/user/idle time separately from
lisa's binning stuff, but make the two compatible.
-  KernelStats used to directly implement the pImpl idiom, but
it makes more sense to just remove the level of indirection and
make the exec context have a pointer to the stats.
-  Factor common code out of LinuxSystem and Tru64System and put
it into the System base class.  While doing that, make all
constructors take a pointer to a parameter struct instead of
naming the parameters individually to make it much easier to add
parameters to these classes.

SConscript:
    Move the function tracking and binning stuff around.
arch/alpha/ev5.cc:
    kernelStats is now a pointer
arch/alpha/pseudo_inst.cc:
    kernelStats is now a pointer
    the parameters to the system have been moved into their own
    struct
base/trace.hh:
    provide a little functor class for wrapping a string that
    can allow you to define name() in any scope very simply
    for use with DPRINTF
cpu/base_cpu.cc:
    New order of arguments for consistency.
cpu/exec_context.cc:
    kernelStats no longer has the level of indirection in it,
    execContext has the indirection now.  so, kernelStats is a pointer.
    We also need a pointer to the kernelBinning stuff from the system
    and we need to figure out if we want to do binning or not.
    Move a whole bunch of code into kern_binning.cc so it's all
    in the same place.
cpu/exec_context.hh:
    We want pointers to the kernel binning/stats stuff and we'll
    have the exec_context and system have the level of indirection
    instead of having the extra layer in the kernel stats class.
cpu/simple_cpu/simple_cpu.cc:
    call through the exec context to do the special binning
    stuff.
kern/kernel_stats.cc:
kern/kernel_stats.hh:
    Re-organize the stats stuff and remove the level of indirection
    (that was there to simplify building) and move the binning stuff
    into its own class/file.

kern/linux/linux_system.hh:
kern/tru64/tru64_system.cc:
kern/tru64/tru64_system.hh:

    that it can be shared between linux, tru64, and whatever else
    we decide to support in the future.

    Make the constructor take a pointer to a parameter struct so that
    it is easier to pass parameters to the parent.
kern/system_events.cc:
    move the majority of the binning code into the Kernel::Binning class
    in the kern_binning file
kern/system_events.hh:
    FnEvents only need to know the bin
    create the Idle start event to find the PCBB of the idle

Lisa Hsu 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
kern/tru64/tru64_events.cc:
    remove FS_MEASURE #defs.  add more DPRINTF's.  manage an anomaly that happens when tracking idle_thread.
kern/tru64/tru64_events.hh:
    remove FS_MEASURE #defs
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.
kern/tru64/tru64_system.hh:
    remove all static binning stuff, add support for dynamic
sim/system.cc:
    change nonPath bin name to Kernel, remove FS_MEASURE
sim/system.hh:
    change nonPath to Kernel

Nathan Binkert d1e12b57ce We only need to choose that we do want binning, or we don't.
no need for multiple bin classes.  If multiple bins are needed, we
can always do it with ini type config instead.

kern/tru64/tru64_events.hh:
sim/system.cc:
sim/system.hh:
    No more GenBin always use MainBin

Lisa Hsu 921b1ee87b Add the ability to track stats in user defined sets of function calls. code can be generated via the base/instrum_codegen.pl script to easily change the functions being tracked. the only thing the user needs to do is add code in tru64System to change how the callerMap is populated.
command line:

m5.* <config file> <args> --server.system:bin=true to track function calls in the server
m5.* <config file> <args> --client.system:bin=true to track function calls in the client

base/statistics.cc:
    make an adjustment to the way stats are printed for FS_MEASURE
base/statistics.hh:
    add a name() virtual function to GenBin.  add a debug printf for activate().
    add amake MainBin the default bin when FS_MEASURE.
cpu/exec_context.cc:
    initialize swCtx to null upon creation of an xc
cpu/exec_context.hh:
    add a SWContext pointer to every execution context.
cpu/simple_cpu/simple_cpu.cc:
    process calls and returns for FS_MEASURE
cpu/simple_cpu/simple_cpu.hh:
    add this so idleCycles will not be accessed before all stats are constructed
kern/tru64/tru64_events.cc:
    add a FnEvent that fires whenever a function we're tracking is called.  implement the process() virtual function for it.
kern/tru64/tru64_events.hh:
    add FnEvent
kern/tru64/tru64_system.cc:
    send bin parameter to System constructor.  add bin parameter to Tru64System object.  initialize all the FnEvent and MainBin members of Tru64system.  also, populate the calling map that indicates whether a function call is on the path we're tracking.
kern/tru64/tru64_system.hh:
    modify the Tru64System class to support FS_MEASURE
sim/system.cc:
    add a bin parameter to System class.  initialize a MainBin to hold the stats for nonPath.
sim/system.hh:
    add a map of to match bins to function names.  add a swCtx map to map pcb addresses to SWContext *s.  Add some supporting functions.
