2016-10-06ruby: remove the original garnet code.Tushar Krishna
Only garnet2.0 will be supported henceforth.
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.
2015-07-04ruby: drop NetworkMessage classNilay Vaish
This patch drops the NetworkMessage class. The relevant data members and functions have been moved to the Message class, which was the parent of NetworkMessage.
2014-09-01ruby: message buffers: significant changesNilay Vaish
This patch is the final patch in a series of patches. The aim of the series is to make ruby more configurable than it was. More specifically, the connections between controllers are not at all possible (unless one is ready to make significant changes to the coherence protocol). Moreover the buffers themselves are magically connected to the network inside the slicc code. These connections are not part of the configuration file. This patch makes changes so that these connections will now be made in the python configuration files associated with the protocols. This requires each state machine to expose the message buffers it uses for input and output. So, the patch makes these buffers configurable members of the machines. The patch drops the slicc code that usd to connect these buffers to the network. Now these buffers are exposed to the python configuration system as Master and Slave ports. In the configuration files, any master port can be connected any slave port. The file pyobject.cc has been modified to take care of allocating the actual message buffer. This is inline with how other port connections work.
2013-03-22ruby: consumer: avoid using receiver side clockNilay Vaish
A set of patches was recently committed to allow multiple clock domains in ruby. In those patches, I had inadvertently made an incorrect use of the clocks. Suppose object A needs to schedule an event on object B. It was possible that A accesses B's clock to schedule the event. This is not possible in actual system. Hence, changes are being to the Consumer class so as to avoid such happenings. Note that in a multi eventq simulation, this can possibly lead to an incorrect simulation. There are two functions in the Consumer class that are used for scheduling events. The first function takes in the relative delay over the current time as the argument and adds the current time to it for scheduling the event. The second function takes in the absolute time (in ticks) for scheduling the event. The first function is now being moved to protected section of the class so that only objects of the derived classes can use it. All other objects will have to specify absolute time while scheduling an event for some consumer.
2013-02-10ruby: replace Time with Cycles in garnet fixed and flexibleNilay Vaish
2013-02-10ruby: replaces Time with Cycles in many placesNilay Vaish
The patch started of with replacing Time with Cycles in the Consumer class. But to get ruby to compile, the rest of the changes had to be carried out. Subsequent patches will further this process, till we completely replace Time with Cycles.
2013-01-14Ruby: remove reference to g_system_ptr from class MessageNilay Vaish
This patch was initiated so as to remove reference to g_system_ptr, the pointer to Ruby System that is used for getting the current time. That simple change actual requires changing a lot many things in slicc and garnet. All these changes are related to how time is handled. In most of the places, g_system_ptr has been replaced by another clock object. The changes have been done under the assumption that all the components in the memory system are on the same clock frequency, but the actual clocks might be distributed.
2012-11-10ruby: support functional accesses in garnet flexible networkNilay Vaish
2012-10-02ruby: changes to simple networkNilay Vaish
This patch makes the Switch structure inherit from BasicRouter, as is done in two other networks.
2012-09-18ruby: avoid using g_system_ptr for event schedulingNilay Vaish
This patch removes the use of g_system_ptr for event scheduling. Each consumer object now needs to specify upfront an EventManager object it would use for scheduling events. This makes the ruby memory system more amenable for a multi-threaded simulation.
2012-08-27Ruby: Remove RubyEventQueueNilay Vaish
This patch removes RubyEventQueue. Consumer objects now rely on RubySystem or themselves for scheduling events.
2012-07-12Ruby: remove config information from ruby.statsNilay Vaish
This patch removes printConfig() functions from all structures in Ruby. Most of the information is already part of config.ini, and where ever it is not, it would become in due course.
2011-12-31Ruby: Shuffle some of the included filesNilay Vaish
This patch adds and removes included files from some of the files so as to organize remove some false dependencies and include some files directly instead of transitively. --HG-- extra : rebase_source : 09b482ee9ae00b3a204ace0c63550bc3ca220134
2011-05-18garnet: rename and rearrange config parameters.Tushar Krishna
Renamed (message) class to vnet for consistency with rest of ruby. Moved some parameters specific to fixed/flexible garnet networks into their corresponding py files.
2011-04-28network: convert links & switches to first class C++ SimObjectsBrad Beckmann
This patch converts links and switches from second class simobjects that were virtually ignored by the networks (both simple and Garnet) to first class simobjects that directly correspond to c++ ojbects manipulated by the topology and network classes. This is especially true for Garnet, where the links and switches directly correspond to specific C++ objects. By making this change, many aspects of the Topology class were simplified. --HG-- rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/BasicLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/BasicLink.hh rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetRouter_d.py rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetRouter.py
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

2010-12-01ruby: Converted old ruby debug calls to M5 debug callsNilay Vaish
This patch developed by Nilay Vaish converts all the old GEMS-style ruby debug calls to the appropriate M5 debug calls.

2010-06-10ruby: get rid of Vector and use STLNathan Binkert
add a couple of helper functions to base for deleteing all pointers in a container and outputting containers to a stream
2010-06-10ruby: get rid of RefCnt and Allocator stuff use base/refcnt.hhNathan Binkert
This was somewhat tricky because the RefCnt API was somewhat odd. The biggest confusion was that the the RefCnt object's constructor that took a TYPE& cloned the object. I created an explicit virtual clone() function for things that took advantage of this version of the constructor. I was conservative and used clone() when I was in doubt of whether or not it was necessary. I still think that there are probably too many instances of clone(), but hopefully not too many. I converted several instances of const MsgPtr & to a simple MsgPtr. If the function wants to avoid the overhead of creating another reference, then it should just use a regular pointer instead of a ref counting ptr. There were a couple of instances where refcounted objects were created on the stack. This seems pretty dangerous since if you ever accidentally make a reference to that object with a ref counting pointer, bad things are bound to happen.
2010-04-02ruby: get "using namespace" out of headersNathan Binkert
In addition to obvious changes, this required a slight change to the slicc grammar to allow types with :: in them. Otherwise slicc barfs on std::string which we need for the headers that slicc generates.
