and generate an appropriate child object, which knows how to load its text & data into memory
(and symbols, for ecoff only at this point). Ecoff format supports Tru64 binaries, kernel, and
console. A.out format is used by PAL code. Elf support is there and appears to work for
Alpha/Linux binaries, but awaits a Linux syscall emulation layer before further testing.

sim/main.cc:
Initial revision
sim/main.cc:
Added base SMT support to SS3 distribution
sim/main.cc:
Corrected statistics in sim-smt
Added "cnt_*" statistics to sim-smt and sim-outorder
Added execution tracing to sim-outorder
sim/main.cc:
Numerous minor fixes.
Implemented Ideal and Random fetch policies.
Numerous new statistics.
sim/main.cc:
A few minor bug fixes to collapsing RUU & "ideal" fetch policy.
sim/main.cc:
Snapshot of MICRO99 work in progress. Lots of SMT stuff, EIO fixes, etc.
sim/main.cc:
-> New fetch stage:
- Fetch a block at a time
- Execute in fetch
-> Removed execute from ruu_dispatch()
-> Cleaned up
sim/main.cc:
Added build time-stamp to top of simulation log
sim/main.cc:
Corrected error in priority rotation routine
Added -max:mult option
Modified makefile to use egcs compiler
Added the -t option bkdwn.pl
sim/main.cc:
Added memory usage display
Fixed #define for number of RS_LINKs
sim/main.cc:
Should be able to build other simulators (sim-fast, sim-eio, etc.) using
"make -f Makefile.orig" (for Alpha at least, not quite for PISA).
sim/main.cc:
More SMT vs. non-SMT cleanup: 'make sim-X' now works for most X.
sim/main.cc:
Changed function of Fetch/Decode/Dispatch pipe:
a) Fetch only if room in fetch queue
b) Decode only if pipe advanced as a result of dispatching a packet
c) Dispatch a packet only if:
1) Room for all insns in RUU
2) Room for all insns in LSQ
3) Room for all insns in INT Register File
4) Room for all insns in FP Register File
Added ROB structure
a) Instruction is placed in RUU & ROB at dispatch
b) Instruction is removed from RUU at writeback (except stores)
c) Instruction is removed from ROB at commit
Added support for counting physical register usage (INT and FP)
a) subtract from "free" count at dispatch
b) add back when instruction is removed from ROB
Added "my_index" field to RUU_station (simplifies reverse-lookups)
Removed all remaining ptrace stuff
RUU & LSQ now dump squashed instructions instead of marking them squashed
- No cost!
Reworked commit stage to use ROB instea
sim/main.cc:
- Added sc_dist1 stat type as a user-transparent special case of distribution
with unit-size buckets: saves an unnecessary divide on every sample
- Minor changes to compile as C++ code
base/fast_alloc.cc:
base/fast_alloc.hh:
Major reorganization. Split sim-smt.c into multiple files, compile with C++,
split ROB & RUU structures, numerous small formatting and performance changes.
sim/eventq.cc:
sim/eventq.hh:
- Replaced SimpleScalar event queue code with smt_eventq.{cc,hh}
- Eliminated unused cache:flush option
- Initialize bpred history regs and BTB and RAS entries to provide
repeatable results
- Added reset_spec_state() function: cleans up interface to spec_state.c
sim/eventq.cc:
sim/eventq.hh:
Major reorganization of memory-system code and interface.
base/fast_alloc.cc:
sim/eventq.cc:
sim/eventq.hh:
Moved C++ files to .cc/.hh, compile C files with C compiler.
base/dbl_list.hh:
Initial check-in: doubly-linked list template class.
sim/eventq.hh:
Added when_created and when_scheduled time-tags for debugging
base/fast_alloc.hh:
Plug memory leak
sim/eventq.cc:
Runahead_Prefetch memory-system support, including miss notification
events in cache.
sim/eventq.cc:
sim/eventq.hh:
Merged branch "mt-frontend" into trunk of CVS tree
Changes include:
Multi-threaded Fetch & Decode
Correct functionality of branch misprediction fixup (MT only)
Improved stats
base/intmath.cc:
base/intmath.h:
Integer math functions.
base/fast_alloc.cc:
base/fast_alloc.hh:
Remove carriage returns.
base/intmath.h:
Add Min/Max template functions
sim/prog.cc:
sim/prog.hh:
Adding smt-safe and smt-fast. These are functional simulators based on
sim-safe and sim-fast. Despite their names, they do not actually don't
handle multithreaded programs yet. The runfile functionality was
pulled out of sim-smt.cc into its own files. This allows all three
simulators to use runfiles.
NOTE: There is a lot of duplicated code in these three simulators that
should probably be separated out. The macro type definitions in engin.hh
are similar to the definitions in smt-safe.cc and smt-fast.cc
sim/prog.cc:
Add support for loading a kernel with simplescalar. Also add skeleton for
loading a disk image to boot from with simplescalar.
Hook for loading palcode is in place, but not implemented.
Initial parameters passed to kernel at boot time are not passed properly.
sim/prog.cc:
Only support loading kernel/disk image if we're running FULL_SYSTEM
sim/prog.cc:
Make loading PAL a separate operation. Also separate kernel loading and
disk loading so that it can only be done in FULL_SYSTEM. Finally, we need
to also load the console image file. I'm not sure what's in there, maybe
some stuff from SRM, but it's needed for proper execution.
dev/alpha_console.cc:
dev/alpha_console.hh:
Console device implementation from simos. This is a simple device that
supports the necessary console functions for booting.
sim/prog.cc:
sim/prog.hh:
Separate the kernel loader and the program loader for simplicity since they
don't share much code.
arch/alpha/alpha_memory.hh:
Add this somewhat gross hack to take care of the fact that alpha has the
this load locking and conditional store mechanism.
sim/prog.cc:
Enable asids again. This makes multithreaded programs work again.
I guess you could say that this was an accidental commit. Sorry
sim/main.cc:
Clean up Simplescalar copyright notice.
sim/prog.cc:
Allow '-' for stdout as well as stdin in run file.
dev/alpha_console.cc:
dev/alpha_console.hh:
sim/prog.cc:
arch/alpha/alpha_memory.hh:
Replace the interface to the memory system. Basically this change goes
away from the model of passing an address, and a number of bytes and
getting/setting data. This change rather creates a memory_request packet
(a simple struct) that bundles all of the necessary information together
to pass into the memory system when making a request. This makes the
function call syntax consistent even when you have virtual to physical
translation and when you have strange flags like locked, or physical that
you need to pass to your memory system. It has the added benefit of allowing
the layers to pass data to each other, possibly skipping layers in between.
This was necessary for the whacked out behavior that store conditional has
on alpha.
In addition, the entire memory system is now consistent in that it will return
an alignment fault due to an unaligned access. This is necessary to properly
model a full alpha system, but changes the behavior of bogus bad path loads
and stores that access unaligned data. Because
base/fast_alloc.cc:
base/fast_alloc.hh:
Major enhancement of FastAlloc debug code (uncomment #define in
fast_alloc.hh to enable). Can now dump summary of in-use objects
by type and address/type of oldest n objects (thank you RTTI!).
Should be easier to identify memory leaks now.
base/res_list.hh:
file res_list.hh was initially added on branch segmented_iq.
sim/sat_counter.hh:
file sat_counter.hh was initially added on branch segmented_iq.
sim/std_types.hh:
file std_types.hh was initially added on branch segmented_iq.
base/fast_alloc.hh:
base/res_list.hh:
sim/sat_counter.hh:
sim/eventq.cc:
sim/eventq.hh:
sim/prog.cc:
sim/std_types.hh:
Merged branch "segmented_iq"
-> Objectized the IQ and LSQ
-> Implemented Standard, Sezned, and Segmented IQ's
-> Major fixes to wrong-path execution (primarily involving data dependencies)
base/res_list.hh:
g++ is braindead, so I cannot pull template functions out into a .cc file.
Instead, pull large functions out of the class definition and inline them.
This leads to a much more readable class definition.
In addition, since these functions are inlined, youseems to be what is
intended anyway.
sim/prog.cc:
Move some variables to smt_prog so that targets other than sim-smt can use
them.
sim/main.cc:
remove the dlite debugger (for smt at least)
dev/alpha_console.cc:
sim/eventq.cc:
sim/main.cc:
I knew I had done this for a reason
Change 64 bit types back to long for alpha and replace all instances
of stuff like %lld to use FMT64d and the like.
The reason this is necessary is because TRU64 does not understand what
%lld is and will print out "ld" instead of actually printing the
number.
So, PLEASE use the FMTxxx stuff instead of sticking %lld, %llx, %016llx
and such into the code.
sim/main.cc:
Don't want FMT64d for things declared 'long': this doesn't work when
FMT64d evaluates to "%lld". Just use "%ld" instead.
dev/console.cc:
dev/console.hh:
dev/disk_image.cc:
dev/disk_image.hh:
dev/pcireg.h:
dev/simple_disk.cc:
dev/simple_disk.hh:

Update the alpha_console to take advantage of the simple disk interface
sim/eventq.cc:
sim/eventq.hh:
Make it so you can service events that will happen in the future
base/trace.cc:
base/trace.hh:
This is a simple tracing facility.
The idea is that there is a bitvector where each bit represents something
that you may want to trace. The end result is that you can at runtime
turn on and off different tracing statements in the code so that you
only see messages for things that you care about.
This is only currently used in the devices framework, but I would like
to see it eventually replace the debug, warn, and info functions.
sim/intr_control.hh:
Initial abstraction for a processor and interrupt controller
arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
Add full support for the SYSTEM_EV5 model in smt-safe. With this model, the
user should be able to boot Tru64 unix.
Several aspects of the memory subsystem were changed to accomidate this
ability:
- The C memory access functions no longer return an md_fault_type.
- The prot_* functions no longer take a memrequest, and no longer return
an md_fault type. They now take a single address and a size. This is
because the prot_* functions don't need translation abilities, etc.
- The prot_* functions will by default fail to work unless they are
specifically implemented for the class that you want to use them with.
- The unaligned parameter to the READ_* and WRITE_* function calls was added
back so that exceptions that occur on STQ_U, LDQ_U, etc get the proper
faulting address.
- The memory controller now supports adding an arbitrary number of objects
at arbitrary memory ranges so that a variety of devices can be accomidated.
- The physical_memory class now not only emulates a specific amount of memor

Eliminated old SimpleScalar options package from sim_smt, shifting
everything over to new parameter objects fed by .ini-style
configuration files. Parameters can be set on command line using
'--<sec>:<param>=<value>'. All other cmd-line options are assumed
to be config file names, except '-h' prints help msg.
Got rid of *_reg_options(), *_check_options(), *_uninit() calls.
Moved more initialization into constructors; remaining code is now
automagically executed by providing checkParams() and cleanup()
methods on ParamContext-derived objects. (See exetrace.cc, for
example.)
Runfile is gone; processes are initialized as simulation objects.
Split parameter code out of sim_object.{cc,hh} into param.{cc,hh}.
Moved a bunch of CPU object methods from sim_smt.cc to cpu.cc.
smt_reg_stats calls now need to know number of threads. Can be done
by explicit argument to global function, or (for backward
compatibility) calling CPU object method with same parameters as old
global function.

dev/console.hh:
Change the console framework to use the new pollevent stuff.
This adds support for a console that can be attached and detached at runtime
via a tcp connection (telnet). There is also a circular buffer integrated
into the console so that upon connection, any missed console text is output
to the console.
In the future, this should easily allow for multiple system consoles to

Update to BTB functionality
Fixed numerous statistics
Fixed path of store instructions so that they _all_ go through issue stage
Updates to exetrace functionality
sim/eventq.cc:
sim/eventq.hh:
Replaced every-cycle termination checks in sim_main() with events.
Added per-thread instruction-count-based event queues to handle
termination based on committed instruction count. These are now
specified via parameters to the FullCPU object (max_insts_any_thread
and max_insts_all_threads) rather than global parameters under the
[max] context.
Also replaced break_cycle check with DebugBreakEvent.
Some cleanup of eventq.{cc,hh}.

sim/base_cpu.cc:
sim/base_cpu.hh:
sim/main.cc:
sim/sim_object.cc:
sim/sim_object.hh:
Changes to eliminate the global 'the_cpu' pointer to allow for
mutliple CPUs/systems. Specifically:
- Add findMaxThreadsPerCPU() and tickAll() static methods to
BaseCPU class.
- Added generic printExtraOutput() method for all SimObjects,
to dump output at the end of simulation that is not covered by
stats. Use this hook on CPU object to call
dump_floss_reasons(). sim_aux_stats() is now obsolete.
- printExtraOutput() takes an ostream& rather than a FILE*, so
dump_floss_reasons() had to be converted to C++ I/O.
- Fixed a bug in floss_reasons.cc where an additional
mem_access_result_t item (MA_NOT_PREDICTED) did not have a
corresponding entry in mem_access_result_item_descr. This
resulted in "(null)" being printed with sprintf I/O (which no
one had noticed, apparently), but caused a segfault using
streams.
sim/exec_context.hh:
sim/main.cc:
sim/prog.cc:
sim/prog.hh:
sim/sat_counter.hh:
sim/simple_cpu.cc:
Rename many stats to include config hierarchy path, so results from
different CPUs/systems can be distinguished.
Move stats.c/h into C++... renamed to stats.cc/hh. Added overloads
of most stat registration functions to allow 'string' rather than
'char *' stat names & formulas... no more sprintf needed!
sim/base_cpu.cc:
sim/base_cpu.hh:
Add sim_num_insn stats as per-CPU and total number of simulated instructions
so we can continue to calculate sim_inst_rate.
sim/simple_cpu.cc:
Fix sim_num_insn stat for SimpleCPU.
sim/simple_cpu.cc:
sim/simple_cpu.hh:
Move global memory interface objects into SimpleCPU object.
Made read/write functions SimpleCPU members for easier access to same.
Can now do multiple systems in non-FULL_SYSTEM mode.
sim/param.hh:
sim/sim_object.cc:
sim/sim_object.hh:
SimObjects now look in the .ini database first using the object
instance name (e.g., sys.cpu0) *then* using the configuration class
name (e.g., DetailedCPU). This makes it easier to use a common
description but override a few simple things like the workload.

sim/simple_cpu.hh:
Cleanup of full-system global variables, primarily in simple_cpu.cc,
to allow multi-system simulations. (Multiple systems not yet yested
though.) Also changes to build sim_smt in full-system mode (though
with only SimpleCPU and not the full timing CPU for now).
Still to do: minimize changes in SimpleCPU code between full-system
and application modes... way too many ifdefs there. Much of the
full-system stuff moved into SimpleCPU should be put in a new System
object to allow multiprocessor simulations.
Converted last remaining modules from C to C++ (mostly in /old).
Renamed all .c files to .cc and a few .h files to .hh.
Renamed architecture-specific files in arch/$TARGET from
$TARGET.{cc,hh,def} to machine.{cc,hh,def} to get rid of pointless
intermediate files in object directory. Split exo-specific
definitions out of machine.hh into machine_exo.h.
Specifics:
In machine.def, null resource descriptors must be FUClamd_NA (and not
NA) to pass C++ type checking.
Enhanced error checking/reporting in bas

Memtest currently does not test copies, just reads and writes. The multiple MSHR/Cache changes broke copying along the way.

- Merge SLAT changes

- Get simple_cpu and FULL_SYSTEM to compile again. I'm
not sure these will run correctly (simple_cpu should)
but it is an improvement over what's currently available.
Split the engine files into generic, cpu-specific
and isa-specific files to isolate the various parts of
the engine code. This is quite hackish in places due to
machine.def (e.g. see comments in execute.cc). Further
cleanup is warranted but it compiles and passes smt-test.
Later commits will remove unused code.

TONS of improvements to remote kernel debugging.
- Use the pc based events stuff to simulate hardware breakpoints.
- Implement the set/clear breakpoint/watchpoint function, though
only breakpoints are implemented right now.
Both software and hardware breakpoints are implemented as hardware
breakpoints.
- Fix numerous bugs in single stepping, and make temporary breakpoints
use hardware breakpoints instead of software breakpoints.
- Add tons of debugging stuff to help with future remote debugger debugging.
(No, that was not an accidental doubling.)
- Implement part of the query variable function.

base/object_file.hh:
initial framework for sucking in an object file and figuring out some stuff
for it. Support for ecoff and a header for elf. There is nothing for
relocations, but the symbol information is available so an external
program is no longer required for that.
base/symtab.cc:
base/symtab.hh:
Update some of the symbol table stuff to add support for manual insertion of
symbols. This is used by the object file code so that we can read the
table from the object file and stick it into the more efficient symtab
test/Makefile:
test/nmtest.cc:
test program for using the symbol table code. Basically allows one to look
up a symbol in an object file
dev/console.cc:
dev/console.hh:
Clean up the console code, add an input buffer queue to avoid leaving data in

things such as telnet support. There is some minimal telnet support in here
but it isn't working very well, and isn't enabled by default

sim/simple_cpu.cc:
sim/simple_cpu.hh:
Do the badaddr stuff far more intelligently. Basically, what we do now
is first determine if the address goes to any proper device. If not, the
address is bad. If so, ask the device whether the address is any good or
not. The default case is that a device will say that all of its addresses
are good, but there are some devices that don't follow this paradigm.

Also, make the timer interrupt delay parameterizeable (and make the default

base/refcnt.hh:
Simple reference counting class. Could be replaced by boost shared_ptr some
day.
Classes that are reference counted must have exported functions incref()
and decref() for manipulating the reference count. This doesn't have the
convenience of shared_ptr where the shared classes can be used unmodified,
but it also means that the refcnt pointer (the pointer in this code) is
the size of a normal pointer for this system.

arch/alpha/alpha_memory.cc:
sim/simple_cpu.cc:
Memory system enhancements:
- Functional implementation of load-locked/store-conditional in
main_memory object (the functional memory object for non-full-system
mode). This code should eventually be extracted out and applied to
both main_memory and physical_memory so that it works in full-system
mode as well. Moved lock_flag & lock_addr from system registers to
control registers so they're available in non-full-system mode.
- Moved Alpha unaligned access handling back into machine.def. (It
was a flag on the mem request and handled in the memory system, but
that approach appears to be unnecessarily complicated.)
- Cleanup of AlphaMemoryRequest: down from five constructors to one;
Erik's full-word flags are now bits in Nate's flag word.
- Eliminate obsolete memory.h functions, and some unused memory_object
functions.
arch/alpha/vtophys.cc:

sim/simple_cpu.cc:
sim/simple_cpu.hh:
Renamed SimpleCPU::(read|write)_(byte|half|word|qword) to just read &
write, overloaded on the type of the 'data' argument. Merged the
full-system and non-full-system implementations of these eight
original functions into two common template functions.
To support this, also renamed (read|write)[1248] on memory_object and
derivatives to just read & write, again overloaded on the type of the
'data' argument. Many of these functions could now be condensed into
a few template functions (though with a level of indirection so that
the interface can remain virtual). I did not do that though.

dev/pcireg.h:
Instead of having each pci device define its own sim object to represent
the configuration space, just define one TlaserPciDev type and change the
configuration regs as needed.
base/range.hh:
Fix bugs in range parsing code.
sim/eventq.hh:
Uncomment inlined event check (not sure why it was commented out
to begin with).
base/str.hh:
- Add some missing #includes.
- Remove some prefetching stats to shorten log lengths.
- Fix perfect cache to work with new coherence mechanism
(or at least not fail when there is no coherence protocol).
base/range.hh:
Consider whether a range object is valid or not when doing range tests.
Reorganization & minor documentation of range comparison code.

base/remote_gdb.cc:
Don't panic if the execution context isn't the same, just don't execute the
breakpoint since it probably belongs to another instance
sim/memtest.cc:
Removed bcopy_in & bcopy_out (needless aliases for prot_write &
prot_read, respectively). Made prot_read & prot_write public methods
(not protected). Had to change some char arrays to byte_t to keep
compiler happy.
Renamed strcpy_in and strcpy_out to writeString and readString,
respectively, to reduce confusion about the direction they operate.
Also some reformatting for style.
sim/main.cc:
Move some more old simplescalar I/O from stdio to C++ streams.
Some reformatting for style in main.cc as well.
base/inifile.cc:
base/inifile.hh:
Pass -D, -U, and -I args to cpp for ini-file processing. Should make
use of #defines in .ini files much handier, once we get our parser up
to dealing with the resulting whitespace issues.

sim/simple_cpu.cc:
Changes to exetrace code to make it somewhat less schizophrenic so
that it works under non-full-system SimpleCPU. (Previous code assumed
either full-system+simple CPU or non-full-system+detailed CPU.)
Also removed a lot of unused code in simple_cpu.cc.
base/trace.hh:

warnings (which are suppressed by default).
arch/alpha/fake_syscall.cc:
sim/exec_context.cc:
sim/exec_context.hh:
sim/prog.cc:
sim/prog.hh:
sim/simple_cpu.cc:
Syscall emulation (non-full-system) support for multithreaded apps
compiled using Tru64 5.1's pthreads library.
More specifically, you can now associate multiple processors with a
single LiveProcess object (via their workload parameters). Only one
processor will be active initially. The additional processors will
be assigned to handle new "virtual processor" threads as they are
created by the pthreads user library. Functionality is limited, as
we do *not* emulate any kernel scheduling: once a VP thread is created,
it is permanently bound to a simulated CPU. However, most of the
SPLASH-2 benchmarks seem to run on both uni- and dual-processor targets.
Includes total rewrite of syscall emulation (fake_syscall.cc). Only
syscalls that have been needed thus far have been re-implemented in
the new framework. Others will be moved over on demand.
base/trace.cc:
Better dump function
sim/simple_cpu.cc:
The active field of exe_ctx is not used in FULL_SYSTEM

sim/simple_cpu.cc:
Added FULL_SYSTEM wrapper to use of "proc" in tick().
Nate, please check to make sure I didn't break it.
base/inifile.hh:
Added include of vector
base/trace.hh:
- Create a ScsiDevice base class that represents all of the functions that a
SCSI device might want to implement
- Clean up the ScsiDisk class: remove unneeded junk and give better names
- Create a ScsiNone class that is used when a given target has no device
sim/main.cc:
Always use the same random seed to make the memory tester repeatable.
As the comment says, someday we should make this a parameter.
(Do we still need "mysrand()" and "myrand()"?)
sim/memtest.cc:
sim/memtest.hh:

base/trace.hh:
Major update in dma code.
- Separate the io callback into a read callback and a write callback
- Fix the write callback so that the proper data is written back to the
disk and data is copied to the proper place in the data buffer
- Use sim_freq for the tick frequency. (There is still no delay)
- Remove a bunch of unnecessary code
- Make code more concise and remove old cruft
- More Debugging (of course)
- Formatting fixes
- mprotect hack to make sure that dma buffer is not overwritten
sim/exec_context.cc:
sim/exec_context.hh:
Fix broken assertion in main_memory::checkLockedAddrList().
Check for lots of failed store-conditionals and print deadlock warning message.

- Rudimentary thread scheduling for non-full-system support of
pthreads apps. Hopefully this won't go much farther.

- We really don't want to build a thread scheduler in the simulator...
rip all that out, and replace with some basic synchronization
primitives implemented as syscalls. Non-full-system MP apps thus
need to be compiled specially to use these primitives, but it's
plenty good enough to get SPLASH-2 up and running.
These primitives block by suspending the execution context (for
efficient simulation). Studies that care about synch operation
costs should use user-level LL/SC-based primitives instead.
- Implement more than two states (active vs. !active) for an ExecContext.

First pass at compiling with gcc 3.x. Lots of "std::" in header files,
"using namespace std" in source files. (Note policy of not putting "using"
statements in headers or before includes in sources.)
Still not able to compile with gcc 3.2.
Errors:
- Can't create an ifstream from a file descriptor anymore (breaks IniFile).
- "`class MSHR::MSHRegister' is private" errors in mshr.cc and prefetch_cache.cc:
not clear why since it's in the public part of the class declaration.
- cpu.cc:879: can't match a reference and 0 (specifically "no match for `bool ?
SimObjectParam<PipeTrace*>& : int' operator")
- pipetrace.cc: "invalid conversion from `int' to `std::_Ios_Fmtflags'"
Warnings:
- strstream now deprecated... needs some rewriting in sat_counter.hh
and hybrid_pred.hh (need to get all that code out of the headers anyway)
- trace.hh macro problem: cpp now says 'pasting "::" and "Event" does not
give a valid preprocessing token'

printf replacement that uses C++ io streams and is typesafe
Any type that overloads operator<< for use with streams will work with this
structure.
The format string is backwards compatible with printf style format strings,
but the types are not checked, for example, %s doesn't verify that the
type being printed is a string, %d doesn't verify that the type being
printed is an integer. Instead, the various formats just set up the proper
io stream manipulators for printing. So, %#s doesn't mean anything different
from %s, but %#x does mean something different from %x. If the type you are
printing does't care about the #, then nothing changes.

- Added Makefile magic to allow a comprehensive build of
all simulator variants on all archtectures. 'make all'
or 'make TARGET=<arch> all_flavors'
- Added container adaptors and associative_table. Don't
use these quite yet -- they are very expensive to
compile. Am currently converting them over to boost::mpl.
They are used by the new BHGP prefetcher.
- Moved md_sysreg_t reg_t entries to isa_traits. PISA
does not have these sorts of registers.
- Moved ipr accesses to theISAEngineTraits because they
are not generally applicable. These are #ifdef FULL_SYSTEM
in the simulator code -- eventually this should get worked
into the traits structure.

Detailed CPU now compiles in full-system mode (but doesn't run, so I

SLAT code is now protected by '#ifdef USE_SLAT', since it's not currently
compatible with full-system mode. Also, slat.cc is not compiled by
default. We will need a makefile option to do '-DUSE_SLAT' and add
slat.cc to the source list.

dev/etherint.cc:
dev/etherint.hh:
dev/etherlink.cc:
dev/etherlink.hh:
Rework the EtherInt class to represent a generic Ethernet interface. Any
object that wishes to connect to another device and pass ethernet packets
must export an ethernet interface. This makes it possible to connect any
two objects that have ethernet interfaces. For example, one EtherDev can
connect directly to another etherdev, or the two EtherDevs can each attach
to one of the interfaces on an EtherLink to get a fixed bandwidth.
dev/ethertap.cc:
dev/ethertap.hh:
util/tap/Makefile:

The ethertap device and ethertap utility allow a simulator to connect to a

arch/alpha/arguments.cc:
arch/alpha/arguments.hh:
Add support for accessing function arguments from a kernel function.
The class behaves somewhat like a random access iterator so that the user can
access any argument desired, but to get at the data, the user uses the

Make Kernel::Printf take AlphaArguments as a parameter so that a user may
add initial arguments to another version of the kernel function and then
pass an offset arguments class to the function for printing the data.
Also, while we're at it, remove the printing of the cycle. That can be done
by the caller.

Separate the printf event from the debugging printf event. The kernel will

- Reorganize build_test so it generates dependencies
correctly.
- Remove HashTable from spec_memory and replace with
SGI's hash_map extension.
- Put cprintf/ArgList in namespace cp so it doesn't
interfere with g++ 2.95 std::deque (comma operator
gives problems -- this is a g++ 2.95 bug).
- Fix FP register decode in dispatch. PISA registers
> 31 were being counted as FP registers and using
up all of the FP hpysical registers. The code in
commit correctly identified FP registers so the
bogus FP physical register usage was never cleared,
locking up the machine. This is why the SLAT didn't
work correctly. Added isa_traits::isFloatingPointRegister
and ::isIntegerRegister to do this tracking in a
machine-independent way.

base/misc.hh:
- Add m5_assert() macro to print the sim_cycle if the

dev/disk_image.cc:

dev/disk_image.cc:
dev/disk_image.hh:
Rework the object implementation of the copy-on-write disk image.
- Allow a child name and an initial table size to both be specified
- Add a read only flag that determines if changes to the image are written
back to disk.
- If the flag is not read only, and there is no initial image to open, that's
ok, just create an initial empty table.
- If the table is to be written back to disk, schedule an ExitCallback to
write the image back when the simulator exits.

Doxyfile:
Configuration file for doxygen. Generates documentation in /n/zizzer/z/m5docs.
To generate docs, run "doxygen Doxyfile" in the root directory of your copy of the head.
To comment your code you use a javadoc like syntax, a cstyle comment with 2 stars at the front (/**). For example
/** Everything before the first period is a brief description. This is a detailed description.
@param <name> description of parameter to function
@retval <name/type> description of function return value.
@sa (for see also) generate links to other class/enum/member/etc.
*/
You should start your files out with a comment like:
/** @file
Brief description of the file.
Detailed description if needed.
*/

Move Cache only calls (block_size, hit_latency, etc.) out of TimingMemObject and into CPUMemInterface. Changes to everywhere they were called on a TimingMemObj.
sim/param.hh:
Fix handling of operator[] for EnumVectorParam classes.
Also fix some line wrapping problems caused by adding 'std::'.
base/trace.cc:
base/trace.hh:
Extend trace facility to either print immediately to an ostream or
maintain a circular buffer of trace entries (dumpable from debugger
by calling dumpTrace()). Also change flags to use SimpleEnumVectorParam
so we can just give a list of names instead of a big hex value.
sim/exetrace.cc:

Minor cleanup on new tracing code:

(call Trace::rawDump, was Trace::dump)
- added --trace:flags=All to set all trace flag bits
- added --trace:dump_on_exit option to dump trace buffer on normal exit
- DPRINTF now requires 'const char *' for format (not string) so it
doesn't go away by the time buffer is dumped

sim/simple_cpu.hh:
- Make the SLAT useable with SimpleCPU for quick

of the traits classes which should make them
marginally more independent.
- Fix bogus assert in the SLAT code. Alias load/store
values should only be assumed equivalent in non-spec mode.
sim/simple_cpu.cc:
- Must send the saved address to the SLAT for all memory
operations because execution could have overwritten
the base register.

Warnings for any unreferenced parameters within a section can be
suppressed by adding a 'unref_entries_ok=y' parameter to the section.
(The value doesn't matter; the presence of the parameter is all that
is tested.)
By default any unreferenced parameter or parameter section warnings

sim/eventq.cc:
sim/eventq.hh:
sim/system.cc:
Clarify debugging defines:
- DEBUG is either defined or not, but is not given a value. It should
be tested with #ifdef.
- TRACING_ON is always defined, either with a 0 or 1 value. It should
always be tested with #if.
Automatically set TRACING_ON value according to whether DEBUG is defined.
Added -Wundef to warnings to catch '#if DEBUG' cases.
(Yes, '#if DEBUG' does the right thing if DEBUG is not defined, but the
same is not true for '#ifdef TRACING_ON' if TRACING_ON is defined to 0.)
In the long run, perhaps the uses of TRACING_ON outside of the trace
package itself should be converted to use DEBUG.
sim/pc_event.cc:
Looks like a lot of device code has never been compiled w/o TRACING_ON set;
fix up several warnings (mostly unused variables).

Fix up parameter printing controls. Parameters are always printed by
default; new command-line parameter '-q' turns this off. Old system
was broken in two ways: there was no way to turn off printing in the
optimized binary, and controlling printing with a trace flag bit (specified
as an .ini parameter) meant that parameters parsed *before* trace:flags
never got printed.
Also added code to print the names of unspecified parameters as comments
in the output.

sim/simple_cpu.hh:
Full-system detailed CPU almost almost there. Big reorganization of
virtual address translation code, so we can tell an access is uncached
soon enough to suppress it if it's on the wrong path: translation is its
own step now, not hidden inside the (former) VirtualMemory object.
Also a few other changes to avoid bad things on misspeculated paths.
This commit results in *very* small changes in IPCs and MSIPCs (a
few tenths of a percent max on the tests) because some wrong-path
instructions get handled a little differently.
sim/main.cc:
Put quotes around args with spaces when echoing command line.
sim/pc_event.cc:
Process PC Events just before fetching the relevant instruction instead
of just after the previous instruction. Keeps us from missing events
when we take off on misspeculated paths.
** Detailed CPU now gets to single-user prompt!! **

sim/eventq.hh:
sim/main.cc:
sim/sim_events.cc:
sim/sim_events.hh:
sim/simple_cpu.cc:
sim/simple_cpu.hh:
get rid of the TickAllEvent and make it so each cpu has its own tick event.
In the process, the implementation of the virtual functin tick() got moved
into a non virtual function _tick() so that the tick event could be CPU
specific and you wouldn't pay the virtual function call overhead.
This is another step towards being able to not tick a cpu if it has nothing
to do
sim/base_cpu.hh:
sim/simple_cpu.hh:
Now that tick is called via an event, we no longer need a virtual function
sim/base_cpu.hh:
sim/simple_cpu.cc:
sim/simple_cpu.hh:
clean up the tick event stuff and get rid of the TickEvent template class
and just make one for each class since you may want a different process()
function anyway
base/trace.cc:
base/trace.hh:
sim/base_cpu.hh:
sim/pc_event.cc:
sim/pc_event.hh:
Fix up branch predictor's return address stack when we do a SkipFuncEvent.
Since there's no easy way to figure out what thread ID we're on from
the SkipFuncEvent, we just fix thread 0's RAS... will need to fix this
when we get SMT full-system up.
Also:
- Moved RAS tracing stuff to DPRINTFs; added BranchPredRAS trace flag.
- Made BadAddrEvent derive from SkipFuncEvent to eliminate code duplication.
base/trace.cc:
sim/eventq.cc:
sim/eventq.hh:
sim/serialize.cc:
Create a flags bitvector in the event to store flags. Holds what used to be
squashed and scheduled, and also contains a new flag for auto delete.
The auto delete flag will make the eventq responsible for calling delete on
an event. This makes 'delete this' unnecessary in the process() function.
This is most beneficial for events that get squashed since process() never
gets called, and one might want to have the data reclaimed.
To use the autodelete functionality with squash, a few events were cleaned up
and reorganized
sim/exec_context.cc:
sim/exec_context.hh:
sim/pc_event.cc:
sim/simple_cpu.cc:
Add thread_num field to ExecContext so it knows which CPU thread
context it represents. Need this for the SkipFuncEvent RAS fixup,
but seems generally useful.

move interrupt set/clear routines into the .cc file and make them virtual

base/trace.cc:
base/trace.hh:
New trace flags generation via perl script. Now if you want to add a
flag you just type it once (in the script) and all the C++ is generated
automagically. Also supports "compound" flags that can be specified
on the command line and map to multiple regular flags.
Switched trace flags from 64-bit bitmap to vector<bool> for scalability.

the trace buffer. From gdb, call "echoTrace(1)" to enable, or
"echoTrace(0)" to disable. As a side effect, semantics of setting
both trace:bufsize and trace:file are different now (will buffer
and send to file, where old version would just buffer), but I doubt
anyone ever did that anyway. See comments in file for more details.

rundiff utility
Normal diff reads in all of both input files and tries to generate a minimal
diff, for super long trace files, this is bad because it takes forever and
you run out of memory. rundiff is designed to scan the input files and
compare only 2000 lines at a time. This way memory won't run out and a user
can use fifos for input files.

- use the stat_print_descriptions variable that the old stats package provides
this is just a quick hack for now. When the old stats package goes away,

When a formula operates on vectors, it is incorrect to do calculate
the formula for each vector element, and then sum the final formula
vector. The correct way is to sum the individual vectors at the leaves
of the expression tree. And then perform the calculation as if it were
on scalar values.
Assume we have vectors A, and B, and X = A * B
The old way would have been: total(X) = total(A * B)
The new way is total(X) = total(A) * total(B)
Per thread miss rates are and example of something that would be calculated
incorrectly. If you were to sum all of the miss rates, you could get
a number greater than one. Calculating the overall miss rate should
just be overall misses / overall accesses
base/statistics.cc:

Create a #define STAT_DISPLAY_COMPAT that makes the new stat package output

integer types. It also allows me to add a workaround for string format widths.
Finally, it allows me to accept stringstream directly as an argument without
having to use the .str() member.

new way:

;
This allows you to specify any information about the stats, and do it in any
order. It also cleans up the kinda crufty setFormat interfaces.

base/statistics.hh:
Two new flags: nozero, and nonan. This will supress printing stats if they
are zero or NAN. For example, it will cause vector elements to be skipped
if there is no value, or it will cause distribution buckets to be skipped.
(or an entire scalar stat to be skipped.) This can be used in conjunction
with prereq. The difference with prereq, is that prereq just checks if the
other stat has ANY values, and won't selectively ignore individual vector
elements.

Add the ability to ignore trace output from certain sources. The option is
--trace:ignore. It takes a space separated list of SimObjects to ignore.
The SimObject is listed in the normal dotted herarchy notation. (e.g.
system0.cpu0.DL1) If an object is specified, the *all* child objects are
ignored as well. You can use a wildcard (*) to match any object.
To ignore all trace statements from system1:
--trace:ignore"system1"
To ignore all DL1 statements:
--trace:ignore="*.*.DL1"
sim/main.cc:

arch/alpha/alpha_memory.hh:
arch/alpha/ev5.cc:
rework the tlb lookup code so that it uses a map instead of a linear
search.
base/statistics.cc:
a tiny bit of debugging assistance
arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
sim/exec_context.hh:
No need for these functions to be virtual. Given that, they don't need to
have the same interface. This eliminates a useless check in an expensive
function.
arch/alpha/isa_desc:
This is an quick fix for the SimpleSclar-FP-Ops-Don't-Work-Right bug
The SS_COMPATIBLE_FP #define at the top of the file forces the precision to match SS.
This will change the precision for ALL CPU's.
Nate will be making a change shortly so that this not done for Full System
arch/alpha/alpha_memory.cc:
use i-> instead of (*i). (what was I thinking?)
also try to do i-> only once if it can be helped.
base/remote_gdb.cc:
sim/simple_cpu.cc:
Move remote debugger code to where it belongs
clean it up a tad while we're at it.
arch/alpha/isa_desc:
Changes for the SS FP bug:
SS-style FP done only if SS_COMPATIBLE_FP is defined in the makefile
arch/alpha/isa_traits.hh:
sim/memtest.cc:
sim/memtest.hh:
sim/simple_cpu.cc:
sim/simple_cpu.hh:
sim/cache/lzss_compression.cc:
sim/cache/lzss_compression.hh:
The new memory hierarchy. There is still some more changes to come, but this works now. IIC compression is broken, but no one else cares. DMA coherence might be broken (no way to test atm). There are doxygen warnings that I will clear up when I can stay connected for more than 3 minutes.
Doxyfile:
Turn Graphics back on since we have squashed the warnings.
base/misc.hh:
Add #include <assert.h> for those who use m5_assert() macro.
Somehow g++ 3.3 is pickier about this than 3.2.
sim/exetrace.hh:
sim/simple_cpu.cc:
sim/std_types.hh:
Style fixes... mostly changing 'struct foo_bar' to 'FooBar' for some
older parts of the code.
Doxyfile:
Always have a detailed section.
sim/host.hh:
Get rid of an old simplescalar comment (plus improve some other comments).
base/statistics.cc:
base/statistics.hh:
provide a way to get at the subdesc
base/statistics.hh:
Make it possible to counte a sample more than once
base/statistics.cc:
print the right value
base/statistics.cc:
base/statistics.hh:
A bit of debugging support
base/statistics.cc:
base/statistics.hh:
be more consistent
base/statistics.hh:
use the correct axis
base/statistics.hh:
remove dead code
sim/main.cc:
sim/param.cc:
sim/param.hh:
sim/sim_object.cc:
Stats now sent by default to a file called "m5.stats". Get the old
behavior back by saying "--stats:file=cerr" on cmd line.
Parameters and config-file stuff also sent to stats file where they belong.
A few informational messages are sent to both cerr and to the stats file.
Default output is pretty minimal now.
arch/alpha/faults.cc:
base/bitfield.hh:
base/random.cc:
base/random.hh:
sim/static_inst.cc:
test/stattest.cc:
Fix RCS Id strings.
sim/base_cpu.hh:
sim/main.cc:
Check if user forgot to specify any CPUs and print a meaningful
error message (not just "improperly exited event loop!").
base/statistics.cc:
base/statistics.hh:
Make subsequent calls to flags() add more flags instead of change them.
Also add the concept of a reserved flag that the user is not allowed to
set. (Basically for passing around extra parameters in the stats package.)
sim/debug.cc:
sim/param.cc:
sim/param.hh:
sim/prog.cc:
sim/sim_events.cc:
Check that VectorParam objects are valid before we let them be
referenced. Fix up a few places where we were just referencing them
w/o checking.
Also some const cleanup on Param object methods.
sim/sim_object.cc:
sim/sim_object.hh:
Print SimObject class name when complaining about missing/broekn params.
base/inifile.cc:
Add "-undef" to cpp flags to not define system-specific macros.
(A '#define linux 1' was giving me trouble.)
base/statistics.hh:
add support fo subnaming in the y direction for 2d vectors. make the printing of it pretty and compatible with the old style. also, suppress printing of a total for 2d vector if they x dimension is just 1.
base/statistics.cc:
rework a lot of the stuff between #ifdef STAT_DISPLAY_COMPAT so it's neater and
also more accurate. add support for printing subdescriptions.
