H A D | fp.isa | 8588:ef28ed90449d Tue Sep 27 02:48:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> ISA parser: Use '_' instead of '.' to delimit type modifiers on operands. By using an underscore, the "." is still available and can unambiguously be used to refer to members of a structure if an operand is a structure, class, etc. This change mostly just replaces the appropriate "."s with "_"s, but there were also a few places where the ISA descriptions where handling the extensions themselves and had their own regular expressions to update. The regular expressions in the isa parser were updated as well. It also now looks for one of the defined type extensions specifically after connecting "_" where before it would look for any sequence of characters after a "." following an operand name and try to use it as the extension. This helps to disambiguate cases where a "_" may legitimately be part of an operand name but not separate the name from the type suffix. Because leaving the "_" and suffix on the variable name still leaves a valid C++ identifier and all extensions need to be consistent in a given context, I considered leaving them on as a breadcrumb that would show what the intended type was for that operand. Unfortunately the operands can be referred to in code templates, the Mem operand in particular, and since the exact type of Mem can be different for different uses of the same template, that broke things. |

H A D | FormalParamAST.py | 8644:acf68e5a8cd7 Sat Dec 31 17:38:00 EST 2011 Nilay Vaish<nilay@cs.wisc.edu> SLICC: Use pointers for directory entries SLICC uses pointers for cache and TBE entries but not for directory entries. This patch changes the protocols, SLICC and Ruby memory system so that even directory entries are referenced using pointers. 8531:bfc59fbde824 Mon Aug 29 07:34:00 EDT 2011 Nilay Vaish<nilay@cs.wisc.edu> SLICC: Pass arguments by reference Arguments to functions were being passed by value. This patch changes SLICC so that arguments are passed by reference. 8192:be38f7b6ad9e Thu Mar 31 20:18:00 EDT 2011 Lisa Hsu <Lisa.Hsu@amd.com> Ruby: Simplify SLICC and Entry/TBE handling. Before this changeset, all local variables of type Entry and TBE were considered to be pointers, but an immediate use of said variables would not be automatically deferenced in SLICC-generated code. Instead, deferences occurred when such variables were passed to functions, and were automatically dereferenced in the bodies of the functions (e.g. the implicitly passed cache_entry). This is a more general way to do it, which leaves in place the assumption that parameters to functions and local variables of type AbstractCacheEntry and TBE are always pointers, but instead of dereferencing to access member variables on a contextual basis, the dereferencing automatically occurs on a type basis at the moment a member is being accessed. So, now, things you can do that you couldn't before include: Entry foo := getCacheEntry(address); cache_entry.DataBlk := foo.DataBlk; or cache_entry.DataBlk := getCacheEntry(address).DataBlk; or even cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk; 7839:9e556fb25900 Mon Jan 17 19:46:00 EST 2011 Nilay Vaish<nilay@cs.wisc.edu> Change interface between coherence protocols and CacheMemory The purpose of this patch is to change the way CacheMemory interfaces with coherence protocols. Currently, whenever a cache controller (defined in the protocol under consideration) needs to carry out any operation on a cache block, it looks up the tag hash map and figures out whether or not the block exists in the cache. In case it does exist, the operation is carried out (which requires another lookup). As observed through profiling of different protocols, multiple such lookups take place for a given cache block. It was noted that the tag lookup takes anything from 10% to 20% of the simulation time. In order to reduce this time, this patch is being posted. I have to acknowledge that the many of the thoughts that went in to this patch belong to Brad. Changes to CacheMemory, TBETable and AbstractCacheEntry classes: 1. The lookup function belonging to CacheMemory class now returns a pointer to a cache block entry, instead of a reference. The pointer is NULL in case the block being looked up is not present in the cache. Similar change has been carried out in the lookup function of the TBETable class. 2. Function for setting and getting access permission of a cache block have been moved from CacheMemory class to AbstractCacheEntry class. 3. The allocate function in CacheMemory class now returns pointer to the allocated cache entry. Changes to SLICC: 1. Each action now has implicit variables - cache_entry and tbe. cache_entry, if != NULL, must point to the cache entry for the address on which the action is being carried out. Similarly, tbe should also point to the transaction buffer entry of the address on which the action is being carried out. 2. If a cache entry or a transaction buffer entry is passed on as an argument to a function, it is presumed that a pointer is being passed on. 3. The cache entry and the tbe pointers received __implicitly__ by the actions, are passed __explicitly__ to the trigger function. 4. While performing an action, set/unset_cache_entry, set/unset_tbe are to be used for setting / unsetting cache entry and tbe pointers respectively. 5. is_valid() and is_invalid() has been made available for testing whether a given pointer 'is not NULL' and 'is NULL' respectively. 6. Local variables are now available, but they are assumed to be pointers always. 7. It is now possible for an object of the derieved class to make calls to a function defined in the interface. 8. An OOD token has been introduced in SLICC. It is same as the NULL token used in C/C++. If you are wondering, OOD stands for Out Of Domain. 9. static_cast can now taken an optional parameter that asks for casting the given variable to a pointer of the given type. 10. Functions can be annotated with 'return_by_pointer=yes' to return a pointer. 11. StateMachine has two new variables, EntryType and TBEType. EntryType is set to the type which inherits from 'AbstractCacheEntry'. There can only be one such type in the machine. TBEType is set to the type for which 'TBE' is used as the name. All the protocols have been modified to conform with the new interface. |

This patch puts all the functions in the controller's .cc file. This should hopefully take away some time from compilation. 8337:b9ba22cb23f2 Fri Jun 03 14:52:00 EDT 2011 Nilay Vaish<nilay@cs.wisc.edu> SLICC: Remove machine name as prefix to functions Currently, the machine name is appended before any of the functions defined with in the sm files. This is not necessary and it also means that these functions cannot be used outside the sm files. This patch does away with the prefixes. Note that the generated C++ files in which the code for these functions is present are still named such that the machine name is the prefix. 8245:a9d06c894afe Wed Apr 20 21:45:00 EDT 2011 Nathan Binkert <nate@binkert.org> fix some build problems from prior changesets 7839:9e556fb25900 Mon Jan 17 19:46:00 EST 2011 Nilay Vaish<nilay@cs.wisc.edu> Change interface between coherence protocols and CacheMemory The purpose of this patch is to change the way CacheMemory interfaces with coherence protocols.

This patch adds a fault model, which provides the probability of a number of architectural faults in the interconnection network (e.g., data corruption, misrouting).
