2015-09-14ruby: topology: refactor code.Nilay Vaish
2015-09-14ruby: slicc: remove member buffer_expr from Var classNilay Vaish
This was added by changeset 51f40b101a56. Instead, buffer_expr would now be associated with the InPort class.
2015-09-12ruby: perfect switch: refactor codeNilay Vaish
Refactored the code in operateVnet(), moved partly to a new function operateMessageBuffer(). This is required since a later patch moves to having a wakeup event per MessageBuffer instead of one event for the entire Switch.
2015-09-12ruby: simple network: store Switch* in PerfectSwitch and ThrottleNilay Vaish
There are two reasons for doing so: a. provide a source of clock to PerfectSwitch. A follow on patch removes sender and receiver pointers from MessageBuffer means that the object owning the buffer should have some way of providing timing info. b. schedule events. A follow on patch removes the consumer class. So the PerfectSwitch needs some EventManager object to schedule events on its own.

2015-09-05ruby: call setMRU from L1 controllers, not from sequencerNilay Vaish
Currently the sequencer calls the function setMRU that updates the replacement policy structures with the first level caches. While functionally this is correct, the problem is that this requires calling findTagInSet() which is an expensive function. This patch removes the calls to setMRU from the sequencer. All controllers should now update the replacement policy on their own. The set and the way index for a given cache entry can be found within the AbstractCacheEntry structure. Use these indicies to update the replacement policy structures.
2015-09-05ruby: adds set and way indices to AbstractCacheEntryNilay Vaish
2015-09-05ruby: set: reimplement using std::bitsetNilay Vaish
The current Set data structure is slow and therefore is being reimplemented using std::bitset. A maximum limit of 64 is being set on the number of controllers of each type. This means that for simulating a system with more controllers of a given type, one would need to change the value of the variable NUMBER_BITS_PER_SET
2015-09-05ruby: declare all protocol message buffers as parametersNilay Vaish
MessageBuffer is a SimObject now. There were protocols that still declared some of the message buffers are variables of the controller, but not as input parameters. Special handling was required for these variables in the SLICC compiler. This patch changes this. Now all message buffers are declared as input parameters.
2015-09-04mem: Avoid setting markPending if not neededAndreas Hansson
In cases where a newly added target does not have any upstream MSHR to mark as downstreamPending, remember that nothing is marked. This allows us to avoid attempting to find the MSHR as part of the clearing of downstreamPending.
2015-09-04mem: Tidy up CacheSetAndreas Hansson
Minor tweaks and house keeping.
2015-09-04mem: Tidy up the snoop state-transition logicAndreas Hansson
Remove broken and unused option to pass dirty data on non-exclusive snoops. Also beef up the comments a bit.
2015-09-01ruby: remove random seedNilay Vaish
We no longer use the C library based random number generator: random(). Instead we use the C++ library provided rng. So setting the random seed for the RubySystem class has no effect. Hence the variable and the corresponding option are being dropped.
2015-09-01ruby: directory memory: drop unused variable.Nilay Vaish
2015-08-30ruby: specify number of vnets for each protocolNilay Vaish
The default value for number of virtual networks is being removed. Each protocol should now specify the value it needs.
2015-08-30ruby: network: drop member m_in_useNilay Vaish
This member indicates whether or not a particular virtual network is in use. Instead of having a default big value for the number of virtual networks and then checking whether a virtual network is in use, the next patch removes the default value and the protocol configuration file would now specify the number of virtual networks it requires. Additionally, the patch also refactors some of the code used for computing the virtual channel next in the round robin order.
2015-08-30ruby: garnet: mark few functions const in BaseGarnetNetwork.hhNilay Vaish
2015-08-30ruby: slicc: avoid duplicate code for function argument checkNilay Vaish
Both FuncCallExprAST and MethodCallExprAST had code for checking the arguments with which a function is being called. The patch does away with this duplication. Now the code for checking function call arguments resides in the Func class.
2015-08-29ruby: eliminate type uint64 and int64Nilay Vaish
These types are being replaced with uint64_t and int64_t.
2015-08-28ruby: Use the const serialize interface in RubySystemAndreas Sandberg
The new serialization code (kudos to Tim Jones) moves all of the state mangling in RubySystem to memWriteback. This makes it possible to use the new const serialization interface. This changeset moves the cache recorder cleanup from the checkpoint() method to drainResume() to make checkpointing truly constant and updates the checkpointing code to use the new interface.
2015-08-27ruby: handle llsc accesses through CacheEntry, not CacheMemoryNilay Vaish
The sequencer takes care of llsc accesses by calling upon functions from the CacheMemory. This is unnecessary once the required CacheEntry object is available. Thus some of the calls to findTagInSet() are avoided.
2015-08-24mem: Revert requirement on packet addr/size always validAndreas Hansson
This patch reverts part of (842f56345a42), as apparently there are use-cases outside the main repository relying on the late setting of the physical address.
2015-08-21mem: Reflect that packet address and size are always validAndreas Hansson
This patch simplifies the packet, and removes the possibility of creating a packet without a valid address and/or size. Under no circumstances are these fields set at a later point, and thus they really have to be provided at construction time. The patch also fixes a case there the MinorCPU creates a packet without a valid address and size, only to later delete it.
2015-08-21arm, mem: Remove unused CLEAR_LL request flagAndreas Hansson
Cleaning up dead code. The CLREX stores zero directly to MISCREG_LOCKFLAG and so the request flag is no longer needed. The corresponding functionality in the cache tags is also removed.
2015-08-21mem: Remove unused cache squash functionalityAndreas Hansson
Tidying up.
2015-08-21mem: Add explicit Cache subclass and make BaseCache abstractAndreas Hansson
Open up for other subclasses to BaseCache and transition to using the explicit Cache subclass. --HG-- rename : src/mem/cache/BaseCache.py => src/mem/cache/Cache.py
2015-08-21ruby: Move Rubys cache class from Cache.py to RubyCache.pyAndreas Hansson
This patch serves to avoid name clashes with the classic cache. For some reason having two 'SimObject' files with the same name creates problems. --HG-- rename : src/mem/ruby/structures/Cache.py => src/mem/ruby/structures/RubyCache.py
2015-08-21mem: Move cache_impl.hh to cache.ccAndreas Hansson
There is no longer any need to keep the implementation in a header.
2015-08-21cpu: Move invldPid constant from Request to BaseCPUAndreas Hansson
A more natural home for this constant.

2015-08-14ruby: simple network: refactor codeNilay Vaish
Drops an unused variable and marks three variables as const.
2015-08-14ruby: profiler: provide the number of vnets through ruby systemNilay Vaish
The aim is to ultimately do away with the static function Network::getNumberOfVirtualNetworks().

2015-08-14ruby: slicc: use default argument valueNilay Vaish
Before this patch, while one could declare / define a function with default argument values, but the actual function call would require one to specify all the arguments. This patch changes the check for function arguments. Now a function call needs to specify arguments that are at least as much as those with default values and at most the total number of arguments taken as input by the function.
