2012-04-06ruby: set SimpleTiming as the default cpuBrad Beckmann
2012-04-06MEM: Enable multiple distributed generalized memoriesAndreas Hansson
This patch removes the assumption on having on single instance of PhysicalMemory, and enables a distributed memory where the individual memories in the system are each responsible for a single contiguous address range. All memories inherit from an AbstractMemory that encompasses the basic behaviuor of a random access memory, and provides untimed access methods. What was previously called PhysicalMemory is now SimpleMemory, and a subclass of AbstractMemory. All future types of memory controllers should inherit from AbstractMemory. To enable e.g. the atomic CPU and RubyPort to access the now distributed memory, the system has a wrapper class, called PhysicalMemory that is aware of all the memories in the system and their associated address ranges. This class thus acts as an infinitely-fast bus and performs address decoding for these "shortcut" accesses. Each memory can specify that it should not be part of the global address map (used e.g. by the functional memories by some testers). Moreover, each memory can be configured to be reported to the OS configuration table, useful for populating ATAG structures, and any potential ACPI tables. Checkpointing support currently assumes that all memories have the same size and organisation when creating and resuming from the checkpoint. A future patch will enable a more flexible re-organisation. --HG-- rename : src/mem/PhysicalMemory.py => src/mem/AbstractMemory.py rename : src/mem/PhysicalMemory.py => src/mem/SimpleMemory.py rename : src/mem/physical.cc => src/mem/abstract_mem.cc rename : src/mem/physical.hh => src/mem/abstract_mem.hh rename : src/mem/physical.cc => src/mem/simple_mem.cc rename : src/mem/physical.hh => src/mem/simple_mem.hh
2012-04-05Config: corrects the way Ruby attaches to the DMA portsNilay Vaish
With recent changes to the memory system, a port cannot be assigned a peer port twice. While making use of the Ruby memory system in FS mode, DMA ports were assigned peer twice, once for the classic memory system and once for the Ruby memory system. This patch removes this double assignment of peer ports.
2012-03-30Ruby: Remove the physMemPort and instead access memory directlyAndreas Hansson
This patch removes the physMemPort from the RubySequencer and instead uses the system pointer to access the physmem. The system already keeps track of the physmem and the valid memory address ranges, and with this patch we merely make use of that existing functionality. The memory is modified so that it is possible to call the access functions (atomic and functional) without going through the port, and the memory is allowed to be unconnected, i.e. have no ports (since Ruby does not attach it like the conventional memory system).
2012-02-13MEM: Introduce the master/slave port roles in the Python classesAndreas Hansson
This patch classifies all ports in Python as either Master or Slave and enforces a binding of master to slave. Conceptually, a master (such as a CPU or DMA port) issues requests, and receives responses, and conversely, a slave (such as a memory or a PIO device) receives requests and sends back responses. Currently there is no differentiation between coherent and non-coherent masters and slaves. The classification as master/slave also involves splitting the dual role port of the bus into a master and slave port and updating all the system assembly scripts to use the appropriate port. Similarly, the interrupt devices have to have their int_port split into a master and slave port. The intdev and its children have minimal changes to facilitate the extra port. Note that this patch does not enforce any port typing in the C++ world, it merely ensures that the Python objects have a notion of the port roles and are connected in an appropriate manner. This check is carried when two ports are connected, e.g. bus.master = memory.port. The following patches will make use of the classifications and specialise the C++ ports into masters and slaves.
2012-01-30Ruby: Connect system port in Ruby network testAndreas Hansson
This patch moves the connection of the system port to create_system in Ruby.py. Thereby it allows the failing Ruby test (and other Ruby systems) to run again.
2012-01-17MEM: Add port proxies instead of non-structural portsAndreas Hansson
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy. The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy --HG-- rename : src/mem/vport.cc => src/mem/fs_translating_port_proxy.cc rename : src/mem/vport.hh => src/mem/fs_translating_port_proxy.hh rename : src/mem/translating_port.cc => src/mem/se_translating_port_proxy.cc rename : src/mem/translating_port.hh => src/mem/se_translating_port_proxy.hh
2012-01-11Ruby: Use map option for selecting b/w sparse and memory vectorNilay Vaish
2012-01-10Ruby: remove the files related to the tracerNilay Vaish
The Ruby Tracer is out of date with the changes that are being carried out to support checkpointing. Hence, it needs to be removed.

2011-11-04GARNET: adding a fault model for resilient on-chip network research.Tushar Krishna
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). These probabilities can be used to realistically inject faults in GARNET and faithfully evaluate the effectiveness of novel resilient NoC architectures.
2011-06-30Ruby: Add support for functional accessesBrad Beckmann ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
This patch rpovides functional access support in Ruby. Currently only the M5Port of RubyPort supports functional accesses. The support for functional through the PioPort will be added as a separate patch.
2011-05-23config: tweak ruby configs to clean up hierarchySteve Reinhardt
Re-enabling implicit parenting (see previous patch) causes current Ruby config scripts to create some strange hierarchies and generate several warnings. This patch makes three general changes to address these issues. 1. The order of object creation in the ruby config files makes the L1 caches children of the sequencer rather than the controller; these config ciles are rewritten to assign the L1 caches to the controller first. 2. The assignment of the sequencer list to system.ruby.cpu_ruby_ports causes the sequencers to be children of system.ruby, generating warnings because they are already parented to their respective controllers. Changing this attribute to _cpu_ruby_ports fixes this because the leading underscore means this is now treated as a plain Python attribute rather than a child assignment. As a result, the configuration hierarchy changes such that, e.g., system.ruby.cpu_ruby_ports0 becomes system.l1_cntrl0.sequencer. 3. In the topology classes, the routers become children of some random internal link node rather than direct children of the topology. The topology classes are rewritten to assign the routers to the topology object first.
2011-04-28network: basic link bw for garnet and simple networksBrad Beckmann
This patch ensures that both Garnet and the simple networks use the bw value specified in the topology. To do so, the patch generalizes the specification of bw for basic links. This value is then translated to the specific value used by the simple and Garnet networks. Since Garent does not support non-uniformed link bandwidth, the patch also adds a check to ensure all bws are equal. --HG-- rename : src/mem/ruby/network/BasicLink.cc => src/mem/ruby/network/simple/SimpleLink.cc rename : src/mem/ruby/network/BasicLink.hh => src/mem/ruby/network/simple/SimpleLink.hh rename : src/mem/ruby/network/BasicLink.py => src/mem/ruby/network/simple/SimpleLink.py
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

The patch includes direct support for the MI example protocol.
2010-03-21ruby: Added a mesh network with directories at the cornersBrad Beckmann
The patch creates a specific mesh network where directories are at the corners. The patch is a good example of how to create an arbitrary network, similar to the old file specified network, while leveraging scripts and loops when possible.

2010-01-29ruby: convert to M5 MemorySizeBrad Beckmann
Converted both ruby caches and directory memory to use the M5 MemorySize python type.
2010-01-29ruby: cleaned up ruby profilersBrad Beckmann
Cleaned up the ruby profilers by moving the memory controller profiling code out of the main profiler object and into a separate object similar to the current CacheProfiler. Both the CacheProfiler and MemCntrlProfiler are specific to a particular Ruby object, CacheMemory and MemoryControl respectively. Therefore, these profilers should not be SimObjects and created by the python configuration system, but instead private objects. This simplifies the creation of these profilers.
