2011-02-14Info: Clean up some info files.Gabe Black
Get rid of RELEASE_NOTES since we no longer do releases, update some of the information in README, and update the date in LICENSE.
2011-01-07Replace curTick global variable with accessor functions.Steve Reinhardt
This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2011-01-07stats: rename StatEvent() function to schedStatEvent().Steve Reinhardt
This follows the style rules and is more descriptive.
2011-01-07scons: show sources and targets when building, and colorize output.Steve Reinhardt
I like the brevity of Ali's recent change, but the ambiguity of sometimes showing the source and sometimes the target is a little confusing. This patch makes scons typically list all sources and all targets for each action, with the common path prefix factored out for brevity. It's a little more verbose now but also more informative. Somehow Ali talked me into adding colors too, which is a whole 'nother story.
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2010-12-30swig: use <> for system %includes instead of ""Nathan Binkert
2010-12-21stats: allow stats to be reset even if no objects have been instantiatedNathan Binkert
2010-12-21importer: fix error messageNathan Binkert
2010-12-20Params: Fix a broken error message in verifyIp.Gabe Black
2010-11-23Copyright: Add AMD copyright to the param changes I just made.Gabe Black
2010-11-23Params: Add parameter types for IP addresses in various forms.Gabe Black
New parameter forms are: IP address in the format "a.b.c.d" where a-d are from decimal 0 to 255. IP address with netmask which is an IP followed by "/n" where n is a netmask length in bits from decimal 0 to 32 or by "/e.f.g.h" where e-h are from decimal 0 to 255 and which is all 1 bits followed by all 0 bits when represented in binary. These can also be specified as an integral IP and netmask passed in separately. IP address with port which is an IP followed by ":p" where p is a port index from decimal 0 to 65535. These can also be specified as an integral IP and port value passed in separately.

2010-09-22python: get rid of internal.enums package.Steve Reinhardt
Move generated enums into internal.params, which gets imported into object.params, restoring backward compatibility for scripts that expect to find them there.
2010-09-12swig: make all generated files go into the m5.internal packageNathan Binkert
This is necessary because versions of swig older than 1.3.39 fail to do the right thing and try to do relative imports for everything (even with the package= option to %module). Instead of putting params in the m5.internal.params package, put params in the m5.internal package and make all param modules start with param_. Same thing for m5.internal.enums. Also, stop importing all generated params into m5.objects. They are not necessary and now with everything using relative imports we wound up with pollution of the namespace (where builtin-range got overridden). --HG-- rename : src/python/m5/internal/enums/__init__.py => src/python/m5/internal/enums.py rename : src/python/m5/internal/params/__init__.py => src/python/m5/internal/params.py
2010-09-09scons: Stop building the big monolithic swigged params moduleNathan Binkert
kill params.i and create a separate .i for each object (param, enums, etc.)
2010-09-09init: don't build files that centralize python and swig codeNathan Binkert
Instead of putting all object files into m5/object/__init__.py, interrogate the importer to find out what should be imported. Instead of creating a single file that lists all of the embedded python modules, use static object construction to put those objects onto a list. Do something similar for embedded swig (C++) code.
2010-09-09scons: use code_formatter wherever we can in the build systemNathan Binkert
2010-09-09code_formatter: make it easier to insert whitespaceNathan Binkert
a newline by just doing "code()". indent() and dedent() now take a "count" parameter to indent/dedent multiple levels.
2010-09-09swig: don't override SWIG_name anymoreNathan Binkert
It doesn't appear to be necessary and it is somewhat odd. I'm pretty sure that the package parameter to %module does whatever this might have been before. It's necessary in future revisions anyway.
2010-08-17misc: add some AMD copyright noticesSteve Reinhardt
Meant to add these with the previous batch of csets.
2010-08-17sim: revamp unserialization procedureSteve Reinhardt
Replace direct call to unserialize() on each SimObject with a pair of calls for better control over initialization in both ckpt and non-ckpt cases. If restoring from a checkpoint, loadState(ckpt) is called on each SimObject. The default implementation simply calls unserialize() if there is a corresponding checkpoint section, so we get backward compatibility for existing objects. However, objects can override loadState() to get other behaviors, e.g., doing other programmed initializations after unserialize(), or complaining if no checkpoint section is found. (Note that the default warning for a missing checkpoint section is now gone.) If not restoring from a checkpoint, we call the new initState() method on each SimObject instead. This provides a hook for state initializations that are only required when *not* restoring from a checkpoint. Given this new framework, do some cleanup of LiveProcess subclasses and X86System, which were (in some cases) emulating initState() behavior in startup via a local flag or (in other cases) erroneously doing initializations in startup() that clobbered state loaded earlier by unserialize().
2010-08-17sim: fold checkpoint restore code into instantiate()Steve Reinhardt
The separate restoreCheckpoint() call is gone; just pass the checkpoint dir as an optional arg to instantiate(). This change is a precursor to some more extensive reworking of the startup code.
2010-08-17sim: clean up child handlingSteve Reinhardt
The old code for handling SimObject children was kind of messy, with children stored both in _values and _children, and inconsistent and potentially buggy handling of SimObject vectors. Now children are always stored in _children, and SimObject vectors are consistently handled using the SimObjectVector class. Also, by deferring the parenting of SimObject-valued parameters until the end (instead of doing it at assignment), we eliminate the hole where one could assign a vector of SimObjects to a parameter then append to that vector, with the appended objects never getting parented properly. This patch induces small stats changes in tests with data races due to changes in the object creation & initialization order. The new code does object vectors in order and so should be more stable.
2010-08-17sim: move iterating over SimObjects into Python.Steve Reinhardt
2010-08-17sim: fail on implicit creation of orphans via portsSteve Reinhardt
Orphan SimObjects (not in the config hierarchy) could get created implicitly if they have a port connection to a SimObject that is in the hierarchy. This means that there are objects on the C++ SimObject list (created via the C++ SimObject constructor call) that are unknown to Python and will get skipped if we walk the hierarchy from the Python side (as we are about to do). This patch detects this situation and prints an error message. Also fix the rubytester config script which happened to rely on this behavior.
2010-08-17sim: make Python Root object a singletonSteve Reinhardt
Enforce that the Python Root SimObject is instantiated only once. The C++ Root object already panics if more than one is created. This change avoids the need to track what the root object is, since it's available from Root.getInstance() (if it exists). It's now redundant to have the user pass the root object to functions like instantiate(), checkpoint(), and restoreCheckpoint(), so that arg is gone. Users who use configs/common/Simulate.py should not notice.
2010-07-21python: add a sorted dictionary classNathan Binkert
It would be nice if python had a tree class that would do this for real, but since we don't, we'll just keep a sorted list of keys and update it on demand.
2010-07-21python: Add mechanism to override code compiled into the exectuableNathan Binkert
If the user sets the environment variable M5_OVERRIDE_PY_SOURCE to True, then imports that would normally find python code compiled into the executable will instead first check in the absolute location where the code was found during the build of the executable. This only works for files in the src (or extras) directories, not automatically generated files. This is a developer feature!
2010-07-17SimObject: transparently forward Python attribute refs to C++.Steve Reinhardt
This tidbit was pulled from a larger patch for Tim's sake, so the comment reflects functions that haven't been exported yet. I hope to commit them soon so it didn't seem worth cleaning up.
2010-07-05sim: allow SimObject subclasses to define classmethodsSteve Reinhardt
(without requiring a leading underscore) Also a little cleanup on type names in SimObject.py.
2010-07-05sim: fold StartupCallback into SimObjectSteve Reinhardt
There used to be a reason to have StartupCallback be a separate object, but not any more. Now it's just confusing.
2010-06-14util: clean up attrdict and import multiattrdict into m5.utilNathan Binkert
2010-06-14python: use ipython in --interactive if it is availableNathan Binkert
2010-06-03Minor remote GDB cleanup.Steve Reinhardt
Expand the help text on the --remote-gdb-port option so people know you can use it to disable remote gdb without reading the source code, and thus don't waste any time trying to add a separate option to do that. Clean up some gdb-related cruft I found while looking for where one would add a gdb disable option, before I found the comment that told me that I didn't need to do that.
2010-03-10slicc: have a central mechanism for creating a code_formatter.Nathan Binkert
This makes it easier to add global variables like protocol
2010-02-28SmartDict: Make SmartDict an attrdictNathan Binkert
2010-02-23stats: this makes some fixes to AverageStat and AverageVector.Lisa Hsu
Also, make Formulas work on AverageVector. First, Stat::Average (and thus Stats::AverageVector) was broken when coming out of a checkpoint and on resets, this fixes that. Formulas also didn't work with AverageVector, but added support for that.

2009-09-22python: Move more code into m5.util allow SCons to use that code.Nathan Binkert
Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
