Steve Reinhardt 9098010e3f slicc: tweak file enumeration for scons 
Right now .cc and .hh files are handled separately, but then
they're just munged together at the end by scons, so it
doesn't buy us anything.  Might as well munge from the start
since we'll eventually be adding generated Python files
to the list too.

Nathan Binkert 2c5fe6f95e build: fix compile problems pointed out by gcc 4.4 2009-11-04 16:57:01 -08:00
Nathan Binkert 25d9328689 license: Fix license on network model code 
This mostly was a matter of changing the license owner to Princeton
which is as it should have been.  The code was originally licensed
under the GPL but was relicensed as BSD by Li-Shiuan Peh on July 27,
2009.  This relicensing was in an explicit e-mail to Nathan Binkert,
Brad Beckmann, Mark Hill, David Wood, and Steve Reinhardt.

Steve Reinhardt f679630788 Minor cleanup: Use the blockAlign() method where it applies in the cache. 2009-09-26 10:50:50 -07:00
Steve Reinhardt 72cfed4164 Force prefetches to check cache and MSHRs immediately prior to issue. 
This prevents redundant prefetches from being issued, solving the
occasional 'needsExclusive && !blk->isWritable()' assertion failure
in cache_impl.hh that several people have run into.
Eliminates "prefetch_cache_check_push" flag, neither setting of
which really solved the problem.

This is simply a translation of the C++ slicc into python with very minimal

by doing a "diff -wBur".

Slicc can easily be run manually by using util/slicc

Derek Hower 33b28fde7a slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers 
This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.

Steve Reinhardt a13a706a20 Fix setting of INST_FETCH flag for O3 CPU. 
It's still broken in inorder.
Also enhance DPRINTFs in cache and physical memory so we
can see more easily whether it's getting set or not.

Steve Reinhardt 1c28004654 Clean up some inconsistencies with Request flags. 2009-08-01 22:50:13 -07:00
Steve Reinhardt c0755e6085 Rename internal Request fields to start with '_'. 
The inconsistency was causing a subtle bug with some of the
constructors where the params had the same name as the fields.
This is also a first step to switching the accessors over to
our new "standard", e.g., getVaddr() -> vaddr().

Derek Hower e59d0e3e89 ruby: moved cache stats from Profiler to CacheMemory 
Caches are now responsible for their own statistic gathering.  This
requires a direct callback from the protocol on misses, and so all
future protocols need to take this into account.
