1b841a871e - Add capability to auto-generate Param structs from
.mpy SimObject descriptions.  Structs are defined
in simobj/param/ObjectName.hh.
- Move compile-time python params (from CPPDEFINES) to
separate dict from run-time params (from os.environ).
The former are needed to generate proper param structs.
This also helps prevent users from messing things up
by setting the wrong environment vars (which could have
overridden compile-time settings in the old system).
- Other misc cleanup of m5 python package.

SConscript:
    Include simobj/SConscript
build/SConstruct:
    Fix type in comment
python/SConscript:
    Move CPPDEFINES dict-generating code to m5scons.flatten_defines
python/m5/__init__.py:
    - Generate a build_env SmartDict here to hold compile-time
    params (passed in via __main__.m5_build_env).
    - Move panic and env here from config.py.
python/m5/config.py:
    Move panic, env to top level (m5/__init__.py)
python/m5/objects/BaseCPU.mpy:
    Use build_env instead of env for compile-time params
python/m5/smartdict.py:
    Add some comments.
sim/sim_object.hh:
    Include auto-generated Param struct.  Not used yet,
    just here as proof of concept.
test/genini.py:
    Put -E arguments in build_env as well as os.environ

sim/main.cc:
    - Completely rework the command line argument passing to deal with
    changes in python and output files.
    - Update help output to reflect changes.
    - Remove all direct support for .ini files.  They are strictly

    - Remove the --foo:bar=blah syntax for .ini files and add --foo.bar=blah
    syntax for python.  This will generate: foo.bar = 'blah' in the python
    script.
    - Add '-d' to set the output directory.
    - Use new output file code to access the output stream.
sim/serialize.cc:
    use the new code to find the output directory

3ece6ab029 New and improved configuration mechanism. No more writing of
wierd ini files.  The ini files are still used as an intermediate step,
but a sophisticated python library exists to help build them more
easily.

SConscript:
    add the new embedded file stuff
    remove all of the old object description junk
base/inifile.cc:
base/inifile.hh:
    get rid of findDefault and findAppend since they were the source
    of much evil.
base/trace.cc:
    For now, if we don't have the dprintf_stream set up, dump
    to standard out.  We probably want a command line option
    for this.
dev/alpha_console.cc:
    PioDevice now takes a platform parameter.
    All PioDevices must have a pio_latency parameter.  We stick
    a dummy parameter in here for now until we get rid of the
    builder stuff.
dev/alpha_console.hh:
    don't need Platform anymore
dev/baddev.cc:
    PioDevice now takes a platform parameter.
    All PioDevices must have a pio_latency parameter.  We stick
    a dummy parameter in here for now until we get rid of the
    builder stuff. Same for the platform parameter, though we just
    pass the PioDevice a null parameter since it isn't used by
    this device and it's quicker.
dev/baddev.hh:
    fix #include guards
dev/etherlink.cc:
    rename parameters.
dev/ethertap.cc:
    rename parameters
dev/ide_ctrl.cc:
    All devices need an address even if it will get overwritten later.
dev/ide_disk.cc:
    use an enum for the drive ID stuff.
    rename disk_delay -> delay
    Actually, I think that we should implement "cable select" and
    have the controller tell the drive what it is.
dev/io_device.cc:
dev/io_device.hh:
    All IO devices take a Platform *
dev/ns_gige.cc:
    all devices need an io_bus.  rename header_bus to io_bus
    We don't need stuff for the interrupt controller since
    it's all in the platform now.
dev/ns_gige.hh:
    We don't need stuff for the interrupt controller now since
    it's all in the platform.

    we don't need one.
dev/pcidev.cc:
    Move a bunch of common functionality into the PciDev
dev/platform.hh:
    remove unneeded code

    config node.  all sections with a type= are now created,
    the old mechanisms no longer work
sim/builder.hh:
    remove some extra variables since they are found in the ConfigNode
sim/main.cc:
    add a quick hack command line argument -X to dump out the
    embedded files.  (probably should be fixed up a little.)
    accept .mpy files
    printing to the streams has to happen after the hierarchy
    is built since we're moving away from param contexts
sim/param.cc:
    add parsing support for ranges
sim/process.cc:
    isValid isn't very useful anymore.  interpret the names
    stdout, stderr, cout, cerr for the file descriptors
sim/pyconfig/SConscript:
    Add Action handlers for creating an embedded python file
    and for creating an embedded C file.

    use these action handlers to embed all objects found in the objects
    tree into the binary along with the importer and the m5config stuff
sim/pyconfig/m5config.py:
    Major changes to the original configuration file generator.  These
    changes largely involve implementing copy-on-write like semantics
    for all of the SimObjects.  Real documentation must be written.
sim/universe.cc:
    Universe becomes a SimObject since we don't really have the notion of
    param contexts in the python code.

78ae8764a9 add a new phase to the simulator. Basically the simulator now goes
through the following phases.

1) Construct all param contexts
2) Call the checkParams() on each context
3) Build the configuration hierarchy
4) Construct all SimObjects
5) Initialize all SimObjects by calling init() on each one
6) Unserialize the checkpoint
7) Register all statisitcs
8) Check validity of all statistics (after that, no new stats)
9) Reset all stats.
10) Call SimStartup() which calls startup() on all SimObjects,
ParamContexts, and any other object deriving from StartupCallback

SConscript:
    no more SimInit() we have SimStartup() now
sim/param.hh:
    Make all params have a startup callback.
sim/sim_events.cc:
    the init callbacks no longer exist.  We can simplify code by
    using startup().
sim/sim_object.hh:
    Make all SimObjects derive from StartupCallback

f834289a51 Do the targetarch dependency stuff better.
SConscript:
    targetarch is only for headers, not cc files.  move all cc files
    back to arch/alpha, and make the target arch directory do this
    echo '#include "arch/alpha/foo.hh"' > targetarch/foo.hh for every
    header file.  This works a lot better and doesn't kill emacs'
    ability to parse compile outputs

0da150b294 Make targetarch directory in build tree and copy arch/alpha files to it
instead of using symlink.  The symlink broke scons's built-in include
dependency tacking.

Interestingly once it was fixed scons discovered two circular dependency
problems which are also fixed now.

SConscript:
    Make targetarch directory in build tree and copy arch/alpha files to it
    instead of using symlink.  The symlink broke scons's built-in include
    dependency tacking.

e3fb9afa79 Update to make multiple instruction issue and different latencies work.
Also change to ref counted DynInst.

SConscript:
    Add branch predictor, BTB, load store queue, and storesets.
arch/isa_parser.py:
    Specify the template parameter for AlphaDynInst
base/traceflags.py:
    Add load store queue, store set, and mem dependence unit to the
    list of trace flags.
cpu/base_dyn_inst.cc:
    Change formating, add in debug statement.
cpu/base_dyn_inst.hh:
    Change DynInst to be RefCounted, add flag to clear whether or not this
    instruction can commit.  This is likely to be removed in the future.
cpu/beta_cpu/alpha_dyn_inst.cc:
    AlphaDynInst has been changed to be templated, so now this CC file
    is just used to force instantiations of AlphaDynInst.
cpu/beta_cpu/alpha_dyn_inst.hh:
    Changed AlphaDynInst to be templated on Impl.  Removed some unnecessary
    functions.
cpu/beta_cpu/alpha_full_cpu.cc:
    AlphaFullCPU has been changed to be templated, so this CC file is now
    just used to force instantation of AlphaFullCPU.
cpu/beta_cpu/alpha_full_cpu.hh:
    Change AlphaFullCPU to be templated on Impl.
cpu/beta_cpu/alpha_impl.hh:
    Update it to reflect AlphaDynInst and AlphaFullCPU being templated
    on Impl.  Also removed time buffers from here, as they are really
    a part of the CPU and are thus in the CPU policy now.
cpu/beta_cpu/alpha_params.hh:
    Make AlphaSimpleParams inherit from the BaseFullCPU so that it doesn't
    need to specifically declare any parameters that are already in the
    BaseFullCPU.
cpu/beta_cpu/comm.hh:
    Changed the structure of the time buffer communication structs.  Now
    they include the size of the packet of instructions it is sending.
    Added some parameters to the backwards communication struct, mainly
    for squashing.
cpu/beta_cpu/commit.hh:
    Update typenames to reflect change in location of time buffer structs.
    Update DynInst to DynInstPtr (it is refcounted now).
cpu/beta_cpu/commit_impl.hh:
    Formatting changes mainly.  Also sends back proper information
    on branch mispredicts so that the bpred unit can update itself.
    Updated behavior for non-speculative instructions (stores, any
    other non-spec instructions): once they reach the head of the ROB,
    the ROB signals back to the IQ that it can go ahead and issue the
    non-speculative instruction.  The instruction itself is updated so that
    commit won't try to commit it again until it is done executing.
cpu/beta_cpu/cpu_policy.hh:
    Added branch prediction unit, mem dependence prediction unit, load
    store queue.  Moved time buffer structs from AlphaSimpleImpl to here.
cpu/beta_cpu/decode.hh:
    Changed typedefs to reflect change in location of time buffer structs
    and also the change from DynInst to ref counted DynInstPtr.
cpu/beta_cpu/decode_impl.hh:
    Continues to buffer instructions even while unblocking now.  Changed
    how it loops through groups of instructions so it can properly block
    during the middle of a group of instructions.
cpu/beta_cpu/fetch.hh:
    Changed typedefs to reflect change in location of time buffer structs
    and the change to ref counted DynInsts.  Also added in branch
    brediction unit.
cpu/beta_cpu/fetch_impl.hh:
    Add in branch prediction.  Changed how fetch checks inputs and its
    current state to make for easier logic.
cpu/beta_cpu/free_list.cc:
    Changed int regs and float regs to logically use one flat namespace.
    Future change will be moving them to a single scoreboard to conserve
    space.
cpu/beta_cpu/free_list.hh:
    Mostly debugging statements.  Might be removed for performance in future.
cpu/beta_cpu/full_cpu.cc:
    Added in some debugging statements.  Updated BaseFullCPU to take
    a params object.
cpu/beta_cpu/full_cpu.hh:
    Added params class within BaseCPU that other param classes will be
    able to inherit from.  Updated typedefs to reflect change in location
    of time buffer structs and ref counted DynInst.
cpu/beta_cpu/iew.hh:
    Updated typedefs to reflect change in location of time buffer structs
    and use of ref counted DynInsts.
cpu/beta_cpu/iew_impl.hh:
    Added in load store queue, updated iew to be able to execute non-
    speculative instructions, instead of having them execute in commit.
cpu/beta_cpu/inst_queue.hh:
    Updated change to ref counted DynInsts.  Changed inst queue to hold
    non-speculative instructions as well, which are issued only when
    commit signals backwards that a nonspeculative instruction is at
    the head of the ROB.
cpu/beta_cpu/inst_queue_impl.hh:
    Updated to allow for non-speculative instructions to be in the inst
    queue.  Also added some debug functions.
cpu/beta_cpu/regfile.hh:
    Added debugging statements, changed formatting.
cpu/beta_cpu/rename.hh:
    Updated typedefs, added some functions to clean up code.
cpu/beta_cpu/rename_impl.hh:
    Moved some code into functions to make it easier to read.
cpu/beta_cpu/rename_map.cc:
    Changed int and float reg behavior to use a single flat namespace.  In
    the future, the rename maps can be combined to a single rename map to
    save space.
cpu/beta_cpu/rename_map.hh:
    Added destructor.
cpu/beta_cpu/rob.hh:
    Updated it with change from DynInst to ref counted DynInst.
cpu/beta_cpu/rob_impl.hh:
    Formatting, updated to use ref counted DynInst.
cpu/static_inst.hh:
    Updated forward declaration for AlphaDynInst now that it is templated.

a58b834c8e Clean up network header stuff and make it more generic. Use
libdnet when we can instead of our own home grown stuff.

SConscript:

    add generic code for calculating ip/tcp/udp checksums
base/inet.hh:
    -  move crc stuff to crc.hh
    -  #include all of the libdnet stuff.  (this makes base/inet.hh the
    only file you need to include if you want to use this kind of stuff.)
    -  Wrap some of the libdnet structs to get easier access to structure
    members.  These wrappers will automatically deal with masking/shifting/
    byte-swapping.

dev/etherpkt.hh:
    EtherPacket -> PacketData
    remove most of the packet header stuff from teh PacketData
    class and just add a few generic functions for grabbing various
    headers that may exist in the packet.  The old functionality is
    contained in the headers.
dev/ns_gige.cc:
    -  IP -> Ip, UDP -> Udp, TCP ->Tcp when used in variable names
    -  get rid of our own byte swapping functions.
    -  whack checksum code and use libdnet version.
    -  Get pointers to the various packet headers and grab info from
    those headers.  (The byte swapping in the headers now.)
    -  Add stats for Udp Checksums
dev/ns_gige.hh:
    use libdnet for checksum code.
    IP -> Ip, TCP -> Tcp in variable names

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

    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:

be more easily re-used.  This currently uses some cooked up matching
function that I wrote a while ago, but should probably be changed
to use regular expressions in the future.
add doDebugBreak to control breakpoints on a per SimObject basis

SConscript:
    add match
base/stats/events.cc:
base/trace.cc:
    Move the object matching code into a separate file so it can be
    more easily shared
base/trace.hh:
    the object matching code was wrapped up and moved.  adapt.
sim/sim_object.cc:
    add the doDebugBreak flag that can be set on a per-SimObject
    basis.  This will be used in the future to control whether or
    not debug_break() will actually break for a given object.

    provide a function interface that can be called from the debugger.
sim/sim_object.hh:
    add the doDebugBreak flag that can be set on a per-SimObject
    basis.  This will be used in the future to control whether or
    not debug_break() will actually break for a given object.

9dc9523a1c the changeset of partitioned caches. this changeset creates Split tagstore class that makes either an LRU/LRU cache or a LRU/LIFO cache, it is also able to make just a LIFO cache.
SConscript:
    add these files for partitioned caches
base/traceflags.py:
    add Split as a traceflag

9dba9e462f fix the failing regression. the sconscript ("makefile") was missing the etherbus.cc src file.
SConscript:
    THIS is why the regression keeps failing.  it's missing the the etherbus file in the sconscript.

b13e28afbb Initial SCons-based build system. See www.scons.org.
'cd build; scons' will build ALPHA/m5.debug.
Use e.g. 'scons KERNEL/m5.opt' to build other binaries.
Read the comments in build/SConstruct for more details.

base/traceflags.py:
    Take basename of generated cc/hh files from command line instead
    of hardwiring them.  Lets us call the script from a different
    directory and still have the files end up in the right place
    (e.g. "base/traceflags.py base/traceflags").
