e7fa4f2f8e i8254xGBe: major style overhaul. 
Moved DescCache template functions from .hh to .cc file.
Also fixed lots of line-wrapping problems, and some irregular indentation.

6629d9b2bc mem: use single BadAddr responder per system. 
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond.  Now there is just one on
the main memory bus.  The default bus responder on all other buses
is now the downstream cache's cpu_side port.  Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

7f8ea68a30 request: split public and private flags into separate fields. 
This frees up needed space for more public flags.  Also:
- remove unused Request accessor methods
- make Packet use public Request accessors, so it need not be a friend

d90456a486 X86: Implement the stul microop. 
This microop does a store and unlocks the requested address. The RISC86
microop ISA doesn't seem to have an equivalent to this, so I'm guessing that
the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.

d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable.

14808ecac9 o3, inorder: fix FS bug due to initializing ThreadState to Halted. 
For some reason o3 FS init() only called initCPU if the thread state
was Suspended, which was no longer the case.  There's no apparent
reason to check, so I whacked the test completely rather than
changing the check to Halted.
The inorder init() was also updated to be symmetric, though the
previous code was just a fancy no-op.

b146131d18 o3: handle fetch with no active threads correctly. 
This situation can arise now on the first fetch cycle after

7617dcf736 ThreadState: initialize status to Halted in constructor. 
This provides a common initial status for all threads independent
of CPU model (unlike the prior situation where CPUs initialized
threads to inconsistent states).
This mostly matters for SE mode; in FS mode, ISA-specific startupCPU()
methods generally handle boot-time initialization of thread contexts
(since the right thing to do is ISA-dependent).

8882dc1283 Get rid of the Unallocated thread context state. 
Basically merge it in with Halted.
Also had to get rid of a few other functions that
called ThreadContext::deallocate(), including:
 - InOrderCPU's setThreadRescheduleCondition.
 - ThreadContext::exit().  This function was there to avoid terminating
   simulation when one thread out of a multi-thread workload exits, but we
   need to find a better (non-cpu-centric) way.

f0fb3ac060 cpu: provide a wakeup mechanism that can be used to pull CPUs out of sleep. 
Make interrupts use the new wakeup method, and pull all of the interrupt
stuff into the cpu base class so that only the wakeup code needs to be updated.
I tried to make wakeup, wakeCPU, and the various other mechanisms for waking
and sleeping a little more sane, but I couldn't understand why the statistics
were changing the way they were.  Maybe we'll try again some day.

f1430941cf This brings M5 closer to modernity - the kernel being advertised is newer so it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs. 2008-12-05 12:09:29 -05:00

3087be945d Output: Include gzstream package to allow automatically-gzipped output 
The gzstream package provides an ostream-interface for writing gzipped files.
The package comes from:
    http://www.cs.unc.edu/Research/compgeom/gzstream/
And is distributed under the LGPL license. Both the license and version
information has been preservered, though all other files in the package have
been purged. Minor modifications to the code have been made. The output module
detects when a filename ends in .gz and constructs an ogzstream object instead
of an ofstream object. This works for both the create(...) and find(...)
commands. Additionally, since gzstream objects needs to be closed to ensure
proper file termination, I have the output deconstructor deleting all ostream's
that it manages on behalf of find(...). At the moment, the only output file
that I know this functionality works for is stats, i.e. by specifying
"--stats-file=m5stats.txt.gz" on the command line.

I did some of the flags and assertions wrong. Thanks to Brad Beckmann

of the fast. I also screwed up some of the logical functions in the Flags
class.

4d64d7664c SCons: Allow top level directory of EXTRAS able to contain SConscripts. 
The current EXTRAS will fail if the top level directory pointed to by EXTRAS
has a SConscript file in it.  We allow this by including the directory name
of the EXTRA in the build directory which prevents a clash between
src/SConscript and extra/SConscript. Maintain compatibility with older uses
of EXTRAS by adding a -I for each top level extra directory.

We need to add a reference when an object is put on the C++ queue, and remove
a reference when the object is removed from the queue.  This was not happening
before and caused a memory problem.

194f0310d3 safe_cast: add a new cast function for casts that should always succeed. 
In DEBUG mode, this does a dynamic_cast and asserts that the result is
non null.  Otherwise, it just does a static_cast.  Again, this is only
intended for cases where the cast should always succeed and what's
desired is a debugging check to make sure.

b760b99f4d O3CPU: Undo Gabe's changes to remove hwrei and simpalcheck from O3 CPU. Removing hwrei causes 
the instruction after the hwrei to be fetched before the ITB/DTB_CM register is updated in a call pal
call sys and thus the translation fails because the user is attempting to access a super page address.

Minimally, it seems as though some sort of fetch stall or refetch after a hwrei is required. I think
this works currently because the hwrei uses the exec context interface, and the o3 stalls when that occurs.

Additionally, these changes don't update the LOCK register and probably break ll/sc. Both o3 changes were
removed since a great deal of manual patching would be required to only remove the hwrei change.

afb279b1bb output: Make panic/fatal/warn more flexible so we can add some new ones. 
The major thrust of this change is to limit the amount of code
duplication surrounding the code for these functions.  This code also
adds two new message types called info and hack.  Info is meant to be
less harsh than warn so people don't get confused and start thinking
that the simulator is broken.  Hack is a way for people to add runtime
messages indicating that the simulator just executed a code "hack"
that should probably be fixed.  The benefit of knowing about these
code hacks is that it will let people know what sorts of inaccuracies
or potential bugs might be entering their experiments.  Finally, I've
added some flags to turn on and off these message types so command
line options can change them.

e06321091d eventq: convert all usage of events to use the new API.

8291d9db0a eventq: Major API change for the Event and EventQueue structures. 
Since the early days of M5, an event needed to know which event queue
it was on, and that data was required at the time of construction of
the event object.  In the future parallelized M5, this sort of
requirement does not work well since the proper event queue will not
always be known at the time of construction of an event.  Now, events
are created, and the EventQueue itself has the schedule function,
e.g. eventq->schedule(event, when).  To simplify the syntax, I created
a class called EventManager which holds a pointer to an EventQueue and
provides the schedule interface that is a proxy for the EventQueue.
The intent is that objects that frequently schedule events can be
derived from EventManager and then they have the schedule interface.
SimObject and Port are examples of objects that will become
EventManagers.  The end result is that any SimObject can just call
schedule(event, when) and it will just call that SimObject's
eventq->schedule function.  Of course, some objects may have more than
one EventQueue, so this interface might not be perfect for those, but
they should be relatively few.

8d018aef0f Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was done to be consistent with its 
python type of a latency.  In addition, the multiple definitions of profile in the different cpu models caused
problems for intialization of the interval value. If a child class's profile value was defined, the parent
BaseCPU::ProfileEvent interval field would be initialized with a garbage value. The fix was to remove the
multiple redifitions of profile in the child CPU classes.

ede89c2d54 libm5: Create a libm5 static library for embedding m5. 
This should allow m5 to be more easily embedded into other simulators.
The m5 binary adds a simple main function which then calls into the m5
libarary to start the simulation. In order to make this work
correctly, it was necessary embed python code directly into the
library instead of the zipfile hack.  This is because you can't just
append the zipfile to the end of a library the way you can a binary.
As a result, Python files that are part of the m5 simulator are now
compile, marshalled, compressed, and then inserted into the library's
data section with a certain symbol name.  Additionally, a new Importer
was needed to allow python to get at the embedded python code.

Small additional changes include:
- Get rid of the PYTHONHOME stuff since I don't think anyone ever used
it, and it just confuses things.  Easy enough to add back if I'm wrong.
- Create a few new functions that are key to initializing and running
the simulator: initSignals, initM5Python, m5Main.

The original code for creating libm5 was inspired by a patch Michael
Adler, though the code here was done by me.

f90b08a5cc eventq: change the event datastructure back to LIFO. 
The status quo is preferred since it is less likely that people will
rely on LIFO than FIFO, and when we move to a parallelized M5, no

10df68dd72 eventq: new eventq data structure. The new data structure is singly 
linked list sorted by time and priority.  For things of the same time
and priority, a second, circularly linked list maintains the data
structure.  Events of the same time and priority are now inserted in
FIFO order instead of LIFO order.  This dramatically improves the
performance of systems that schedule multiple events at the same time.

The FIFO order version is not preferred to LIFO (because it may cause
people to rely on it), but I'm going to commit it anyway and
immediately commit the preferred LIFO version on top.

I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.

9bd0bfe559 After a checkpoint (and thus a stats reset), the not_idle_fraction/notIdleFraction statistic is really wrong. 
The notIdleFraction statistic isn't updated when the statistics reset, probably because the cpu Status information
was pulled into the atomic and timing cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone
care to comment on the odd naming of the Status instance? It shouldn't just be status because that is confusing
with Port::Status, but _status seems a bit strage too.
