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

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

2011-04-06ruby: fixes to support more types of RubyRequestsBrad Beckmann
2011-03-31CacheMemory: add allocateVoid() that is == allocate() but no return value.Lisa Hsu
This function duplicates the functionality of allocate() exactly, except that it does not return a return value. In protocols where you just want to allocate a block but do not want that block to be your implicitly passed cache_entry, use this function. Otherwise, SLICC will complain if you do not consume the pointer returned by allocate(), and if you do a dummy assignment Entry foo := cache.allocate(address), the C++ compiler will complain of an unused variable. This is kind of a hack to get around those issues, but suggestions welcome.
2011-03-31Ruby: Add new object called WireBuffer to mimic a Wire.Lisa Hsu
This is a substitute for MessageBuffers between controllers where you don't want messages to actually go through the Network, because requests/responses can always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered) because you are, after all, going through a network with contention. For systems where you model multiple controllers that are very tightly coupled and do not actually go through a network, it is a pain to have to write a coherence protocol to account for mixed up request/response orderings despite the fact that it's completely unrealistic. This is *not* meant as a substitute for real MessageBuffers when messages do in fact go over a network.
2011-03-31Ruby: pass Packet->Req->contextId() to Ruby.Lisa Hsu
It is useful for Ruby to understand from whence request packets came. This has all request packets going into Ruby pass the contextId value, if it exists. This supplants the old libruby proc_id value passed around in all the Messages, so I've also removed the unused unsigned proc_id; member generated by SLICC for all Message types.

2011-03-22Ruby: Remove CacheMsg class from SLICCNilay Vaish
The goal of the patch is to do away with the CacheMsg class currently in use in coherence protocols. In place of CacheMsg, the RubyRequest class will used. This class is already present in slicc_interface/RubyRequest.hh. In fact, objects of class CacheMsg are generated by copying values from a RubyRequest object.

2011-03-21This patch adds the network tester for simple and garnet networks.Tushar Krishna
The tester code is in testers/networktest. The tester can be invoked by configs/example/ruby_network_test.py. A dummy coherence protocol called Network_test is also addded for network-only simulations and testing. The protocol takes in messages from the tester and just pushes them into the network in the appropriate vnet, without storing any state.
2011-03-19Ruby: Convert CacheRequestType to RubyRequestTypeNilay Vaish
This patch converts CacheRequestType to RubyRequestType so that both the protocol dependent and independent code makes use of the same request type.
2011-03-19Ruby: Convert AccessModeType to RubyAccessModeNilay Vaish
This patch converts AccessModeType to RubyAccessMode so that both the protocol dependent and independent code uses the same access mode.
2011-03-19Ruby: dma retry fixBrad Beckmann
This patch fixes the problem where Ruby would fail to call sendRetry on ports after it nacked the port. This patch is particularly helpful for bursty dma requests which often include several packets.

2011-03-11Gems: Eliminate the now unused GEMS_ROOT scons variable.Gabe Black
2011-03-11Ruby: Get rid of the dead ruby tester.Gabe Black
None of the code in the ruby tester directory is compiled or referred to outside of that directory. This change eliminates it. If it's needed in the future, it can be revived from the history. In the mean time, this removes clutter and the only use of the GEMS_ROOT scons variable.
2011-03-01Ruby: Fix DPRINTF bugs in PerfectSwitch and MessageBufferNilay Vaish
At a couple of places in PerfectSwitch.cc and MessageBuffer.cc, DPRINTF() has not been provided with correct number of arguments. The patch fixes these bugs.

2011-02-25Ruby: Remove store bufferNilay Vaish
This patch removes the store buffer from Ruby. It is not in use currently. Since libruby is being and store buffer makes calls to libruby, it is not possible to maintain it until substantial changes are made.
2011-02-25Ruby: Remove librubyNilay Vaish
This patch removes libruby_internal.hh, libruby.hh and libruby.cc. It moves the contents to libruby.hh to RubyRequest.hh and RubyRequest.cc files.
2011-02-25Ruby: Make Address.hh independent of RubySystemNilay Vaish
This patch changes Address.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depend on RubySystem have been moved to Address.cc file.
2011-02-25Ruby: Make DataBlock.hh independent of RubySystemNilay Vaish
This patch changes DataBlock.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depende on RubySystem have been moved to DataBlock.cc file.
2011-02-23ruby: automate permission settingBrad Beckmann
This patch integrates permissions with cache and memory states, and then automates the setting of permissions within the generated code. No longer does one need to manually set the permissions within the setState funciton. This patch will faciliate easier functional access support by always correctly setting permissions for both cache and memory states. --HG-- rename : src/mem/slicc/ast/EnumDeclAST.py => src/mem/slicc/ast/StateDeclAST.py rename : src/mem/slicc/ast/TypeFieldEnumAST.py => src/mem/slicc/ast/TypeFieldStateAST.py

2011-02-23ruby: cleaning up RubyQueue and RubyNetwork dprintfsKorey Sewell
Overall, continue to progress Ruby debug messages to more of the normal M5 debug message style - add a name() to the Ruby Throttle & PerfectSwitch objects so that the debug output isn't littered w/"global:" everywhere. - clean up messages that print over multiple lines when possible - clean up duplicate prints in the message buffer
2011-02-14Ruby: Improve Change PerfectSwitch's wakeup functionNilay Vaish
Currently the wakeup function for the PerfectSwitch contains three loops - loop on number of virtual networks loop on number of incoming links loop till all messages for this (link, network) have been routed With an 8 processor mesh network and Hammer protocol, about 11-12% of the was observed to have been spent in this function, which is the highest amongst all the functions. It was found that the innermost loop is executed about 45 times per invocation of the wakeup function, when each invocation of the wakeup function processes just about one message. The patch tries to do away with the redundant executions of the innermost loop. Counters have been added for each virtual network that record the number of messages that need to be routed for that virtual network. The inner loops are only executed when the number of messages for that particular virtual network > 0. This does away with almost 80% of the executions of the innermost loop. The function now consumes about 5-6% of the total execution time.

2011-02-07Orion: Replace printf() with fatal()Nilay Vaish
The code for Orion 2.0 makes use of printf() at several places where there as an error in configuration of the model. These have been replaced with fatal().
2011-02-07ruby: add stdio header in SRAM.hhKorey Sewell
missing header file caused RUBY_FS to not compile
2011-02-06ruby: support to stallAndWait the mandatory queueBrad Beckmann
By stalling and waiting the mandatory queue instead of recycling it, one can ensure that no incoming messages are starved when the mandatory queue puts signficant of pressure on the L1 cache controller (i.e. the ruby memtester). --HG-- rename : src/mem/slicc/ast/WakeUpDependentsStatementAST.py => src/mem/slicc/ast/WakeUpAllDependentsStatementAST.py

2011-02-06mem: Added support for Null data packetBrad Beckmann
The packet now identifies whether static or dynamic data has been allocated and is used by Ruby to determine whehter to copy the data pointer into the ruby request. Subsequently, Ruby can be told not to update phys memory when receiving packets.
