2016-10-06ruby: remove the original garnet code.Tushar Krishna
Only garnet2.0 will be supported henceforth.
2016-10-06config: add port directions and per-router delay in topology.Tushar Krishna
This patch adds port direction names to the links during topology creation, which can be used for better printed names for the links or for users to code up their own adaptive routing algorithms. It also adds support for every router to have an independent latency value to support heterogeneous topologies with the subsequent garnet2.0 patch.
2016-10-06config: make internal links in network topology unidirectional.Tushar Krishna
This patch makes the internal links within the network topology unidirectional, thus allowing any deadlock-free routing algorithms to be specified from the topology itself using weights. This patch also renames Mesh.py and MeshDirCorners.py to Mesh_XY.py and MeshDirCorners_XY.py (Mesh with XY routing). It also adds a Mesh_westfirst.py and CrossbarGarnet.py topologies.
2015-09-16ruby: fix message buffer init orderJoe Gross
The recent changes to make MessageBuffers SimObjects required them to be initialized in a particular order, which could break some protocols. Fix this by calling initNetQueues on the external nodes of each external link in the constructor of Network. This patch also refactors the duplicated code for checking network allocation and setting net queues (which are called by initNetQueues) from the simple and garnet networks to be in Network.
2015-09-16ruby: rename System.{hh,cc} to RubySystem.{hh,cc}David Hashe
The eventual aim of this change is to pass RubySystem pointers through to objects generated from the SLICC protocol code. Because some of these objects need to dereference their RubySystem pointers, they need access to the System.hh header file. In src/mem/ruby/SConscript, the MakeInclude function creates single-line header files in the build directory that do nothing except include the corresponding header file from the source tree. However, SLICC also generates a list of header files from its symbol table, and writes it to mem/protocol/Types.hh in the build directory. This code assumes that the header file name is the same as the class name. The end result of this is the many of the generated slicc files try to include RubySystem.hh, when the file they really need is System.hh. The path of least resistence is just to rename System.hh to RubySystem.hh. --HG-- rename : src/mem/ruby/system/System.cc => src/mem/ruby/system/RubySystem.cc rename : src/mem/ruby/system/System.hh => src/mem/ruby/system/RubySystem.hh
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.
2015-07-10ruby: replace global g_abs_controls with per-RubySystem varBrandon Potter
This is another step in the process of removing global variables from Ruby to enable multiple RubySystem instances in a single simulation. The list of abstract controllers is per-RubySystem and should be represented that way, rather than as a global. Since this is the last remaining Ruby global variable, the src/mem/ruby/Common/Global.* files are also removed.
2015-07-10ruby: replace g_ruby_start with per-RubySystem m_start_cycleBrandon Potter
This patch begins the process of removing global variables from the Ruby source with the goal of eventually allowing users to create multiple Ruby instances in a single simulation. Currently, users cannot do so because several global variables and static members are referenced by the RubySystem object in a way that assumes that there will only ever be a single RubySystem. These need to be replaced with per-RubySystem equivalents. This specific patch replaces the global var g_ruby_start, which is used to calculate throughput statistics for Throttles in simple networks and links in Garnet networks, with a RubySystem instance var m_start_cycle.

All the implementations were doing the same things.
2014-03-20ruby: garnet: convert network interfaces into clocked objectsNilay Vaish
This helps in configuring the network interfaces from the python script and these objects no longer rely on the network object for the timing information.

2013-09-06ruby: network: shorten variable namesNilay Vaish
2013-06-28ruby: network: remove reconfiguration codeNilay Vaish
This code seems not to be of any use now. There is no path in the simulator that allows for reconfiguring the network. A better approach would be to take a checkpoint and start the simulation from the checkpoint with the new configuration.
2013-04-23ruby: patch checkpoint restore with garnetNilay Vaish
Due to recent changes to clocking system in Ruby and the way Ruby restores state from a checkpoint, garnet was failing to run from a checkpointed state. The problem is that Ruby resets the time to zero while warming up the caches. If any component records a local copy of the time (read calls curCycle()) before the simulation has started, then that component will not operate until that time is reached. In the context of this particular patch, the Garnet Network class calls curCycle() at multiple places. Any non-operational component can block in requests in the memory system, which the system interprets as a deadlock. This patch makes changes so that Garnet can successfully run from checkpointed state. It adds a globally visible time at which the actual execution started. This time is initialized in RubySystem::startup() function. This variable is only meant for components with in Ruby. This replaces the private variable that was maintained within Garnet since it is not possible to figure out the correct time when the value of this variable can be set. The patch also does away with all cases where curCycle() is called with in some Ruby component before the system has actually started executing. This is required due to the quirky manner in which ruby restores from a checkpoint.
2013-03-22ruby: network: move routers from topology to networkNilay Vaish
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
2012-08-27Ruby: 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.
2012-03-19Garnet: Stats at vnet granularity + code cleanupTushar Krishna
This patch (1) Moves redundant code from fixed and flexible networks to BaseGarnetNetwork. (2) Prints network stats at vnet granularity.
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
2011-05-18slicc: added vnet_type field to identify response vnets from othersTushar Krishna
Identifying response vnets versus other vnets will allow garnet to determine which vnets will carry data packets, and which will carry ctrl packets, and use appropriate buffer sizes (since data packets are larger than ctrl packets). This in turn allows the orion power model to accurately estimate buffer power.
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: set the ExtLink bw to 16 bytesBrad Beckmann
Therefore all links by default are 16 bytes wide and thus work with Garnet's uniform link bandwidth assumption.
2011-04-28network: moved network config paramsBrad Beckmann
Moved the buffer_size, endpoint_bandwidth, and adaptive_routing params out of the top-level parent network object and to only those networks that actually use those parameters.
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

2011-04-28ruby: moved topology to the top network directoryBrad Beckmann
Moved the Topology class to the top network directory because it is shared by both the simple and Garnet networks. --HG-- rename : src/mem/ruby/network/simple/Topology.cc => src/mem/ruby/network/Topology.cc rename : src/mem/ruby/network/simple/Topology.hh => src/mem/ruby/network/Topology.hh

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.
