Gabe Black a6600fdd88 Devices: Make the Intel8254Timer device only use pointers to its counters. 2008-10-11 01:49:39 -07:00
Gabe Black 539563e04b X86: Make the CMOS and I8259 devices use IntDev and IntPin. 2008-10-11 01:45:25 -07:00
Gabe Black 119e127d71 X86: Create the IntDev and IntPin system. 
The IntDev class is a base for anything that supports IntPins. IntPins allow
devices to generically trigger interrupts on a particular pin of an IntDev
device without having to know what the device is or what pin they're attached
to.

Nathan Binkert 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.

Nathan Binkert 70dbe61ffc jobfile: Add support for dictionaries as jobfile options. 
If the same dictionary option is seen in several options, those
dictionaries are composed.  If you define the same dictionary key in
multiple options, the system flags an error.
Also, clean up the jobfile code so that it is more debuggable.

Nathan Binkert 94b08bed07 SimObjects: Clean up handling of C++ namespaces. 
Make them easier to express by only having the cxx_type parameter which
has the full namespace name, and drop the cxx_namespace thing.
Add support for multiple levels of namespace.

Nathan Binkert e06321091d eventq: convert all usage of events to use the new API. 
For now, there is still a single global event queue, but this is
necessary for making the steps towards a parallelized m5.
 2008-10-09 04:58:24 -07:00
Nathan Binkert 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.

Nathan Binkert 68c75c589b pdb: Try to make pdb work better. 
I've done a few things here.  First, I invoke the script a little bit
differently so that pdb doesn't get confused.  Second, I've stored the
actual filename in the module's __file__ so that pdb can find the
source file on your machine.

Nathan Binkert eb89a23556 eventq: Don't use inline friend function when a static function will do. 
Another good reason to avoid this is that swig will try to wrap the friend,
but it won't try to wrap a private static function.
 2008-10-09 04:58:23 -07:00
Nathan Binkert a589eb4053 SCons: add code to provide a libm5 shared library. 
Targets look like libm5_debug.so.  This target can be dynamically
linked into another C++ program and provide just about all of the M5
features.  Additionally, this library is a standalone module that can
be imported into python with an "import libm5_debug" type command
line.

Nathan Binkert 80d9be86e6 gcc: Add extra parens to quell warnings. 
Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off.  Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.
