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

ee96799519 Initial cleanup pass of lisa's function call tracking
code.

base/statistics.hh:
    We're getting rid of FS_MEASURE, but for now, we're going
    to still use a compile time flag to turn on and off binning
    of statistics.  (The flag is STATS_BINNING)
cpu/exec_context.cc:
cpu/exec_context.hh:
kern/tru64/tru64_system.cc:
    get rid of FS_MEASURE
cpu/simple_cpu/simple_cpu.cc:
    yank the function call tracking code out of the cpu and move
    it into the software context class itself.
kern/tru64/tru64_system.hh:
    get rid of FS_MEASURE
    move all of the tacking stuff to the same place.
sim/system.hh:
    cleanup

a03221b6ca track the idle_thread() function in the kernel, so that we can know if we are idle during a run.
kern/tru64/tru64_system.cc:
    autogen for new tracked function

    add to fn name map
kern/tru64/tru64_system.hh:

3a99657c8f change the path that i track from two separate paths to one.
kern/tru64/tru64_system.cc:
    the automatic generated code...
    also, change the way i populate the map.  now, instead of tcp_ouput being
    the head of its own path, put it under tcp_sosend, which is under sosend.
kern/tru64/tru64_system.hh:
    automatically generatd changes

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.

91cb532f9f Make FullCPU schedule its TickEvent when one of its contexts becomes active.
This fixes detailed-mpboot, which was broken as of my last change.
Also clean up some of the ExecContext status initialization.

cpu/base_cpu.hh:
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
    BaseCPU::registerExecContexts() no longer needs to be virtual.
cpu/exec_context.cc:
    Initialize _status directly... don't use setStatus() as this will notify the CPU
    of the change before it is ready.
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
cpu/exec_context.hh:
    Don't need initStatus() any more.
cpu/simple_cpu/simple_cpu.cc:
    Move execCtxStatusChg() from header to .cc file.
    No longer need specialized version of registerExecContexts to schedule TickEvent.
cpu/simple_cpu/simple_cpu.hh:
    Move execCtxStatusChg() from header to .cc file.
    CPU::execCtxStatusChg() now takes thread_num as arg (must be 0 for SimpleCPU).
    No longer need specialized version of registerExecContexts to schedule TickEvent.
kern/tru64/tru64_system.cc:
    Don't need initRegs; the PC etc. get initialized in the CPU constructor.
    ExecContexts start out as Unallocated, so no need to set them to Unallocated here.

f5da73b688 Initial support for CPU switching. New SamplingCPU object encompasses a set
of CPUs that get switched round-robin (though currently we're only shooting for
two CPUs and one switch event, and even that doesn't quite work yet).  Registration
of ExecContexts with System/Process object factored out so we can create two CPUs
but only register one of them at a time.  Also worked at making behavior and naming
in System and Process objects more consistent.

    Rename ipr_init to initIPRs and get rid of unused mem arg.
arch/alpha/fake_syscall.cc:
    Process:numCpus is now a function (not a data member).

4759c203c7 Remove all of the Tru64 specific stuff from the base System object
into its own Tru64System object.  Also remove the System builder
stuff and create a Tru64System builder.  This makes it much
simpler to support more operating systems.
