2016-10-14config: Make configs/common a Python packageAndreas Hansson
Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.
2016-10-13ruby: Fix regressions and make Ruby configs Python packagesAndreas Hansson
This patch moves the addition of network options into the Ruby module to avoid the regressions all having to add it explicitly. Doing this exposes an issue in our current config system though, namely the fact that addtoPath is relative to the Python script being executed. Since both example and regression scripts use the Ruby module we would end up with two different (relative) paths being added. Instead we take a first step at turning the config modules into Python packages, simply by adding a __init__.py in the configs/ruby, configs/topologies and configs/network subdirectories. As a result, we can now add the top-level configs directory to the Python search path, and then use the package names in the various modules. The example scripts are also updated, and the messy path-deducing variations in the scripts are unified.
2016-10-06config: add a separate config file for the network.Tushar Krishna
This patch adds a new file configs/network/Network.py to setup the network, instead of doing that within Ruby.py.
2016-10-06ruby: rename ALPHA_Network_test protocol to Garnet_standalone.Tushar Krishna
Over the past 6 years, we realized that the protocol is essentially used to run the garnet network in a standalone manner, and feed standard synthetic traffic patterns through it.
2016-08-22config: KVM acceleration for apu_se.pyDavid Hashe
Add support for using KVM to accelerate APU simulations. The intended use case is to fast-forward through runtime initialization until the first kernel launch.
2016-08-10ruby: Implement support for functional accesses to PIO rangesAndreas Sandberg
There are cases where we want to put boot ROMs on the PIO bus. Ruby currently doesn't support functional accesses to such memories since functional accesses are always assumed to go to physical memory. Add the required support for routing functional accesses to the PIO bus.

2015-07-20ruby: more flexible ruby tester supportBrad Beckmann
This patch allows the ruby random tester to use ruby ports that may only support instr or data requests. This patch is similar to a previous changeset (8932:1b2c17565ac8) that was unfortunately broken by subsequent changesets. This current patch implements the support in a more straight-forward way. Since retries are now tested when running the ruby random tester, this patch splits up the retry and drain check behavior so that RubyPort children, such as the GPUCoalescer, can perform those operations correctly without having to duplicate code. Finally, the patch also includes better DPRINTFs for debugging the tester.

2015-08-14ruby: Protocol changes for SimObject MessageBuffersJoel Hestness
2015-08-14ruby: Expose MessageBuffers as SimObjectsJoel Hestness
Expose MessageBuffers from SLICC controllers as SimObjects that can be manipulated in Python. This patch has numerous benefits: 1) First and foremost, it exposes MessageBuffers as SimObjects that can be manipulated in Python code. This allows parameters to be set and checked in Python code to avoid obfuscating parameters within protocol files. Further, now as SimObjects, MessageBuffer parameters are printed to config output files as a way to track parameters across simulations (e.g. buffer sizes) 2) Cleans up special-case code for responseFromMemory buffers, and aligns their instantiation and use with mandatoryQueue buffers. These two special buffers are the only MessageBuffers that are exposed to components outside of SLICC controllers, and they're both slave ends of these buffers. They should be exposed outside of SLICC in the same way, and this patch does it. 3) Distinguishes buffer-specific parameters from buffer-to-network parameters. Specifically, buffer size, randomization, ordering, recycle latency, and ports are all specific to a MessageBuffer, while the virtual network ID and type are intrinsics of how the buffer is connected to network ports. The former are specified in the Python object, while the latter are specified in the controller *.sm files. Unlike buffer-specific parameters, which may need to change depending on the simulated system structure, buffer-to-network parameters can be specified statically for most or all different simulated systems.
2015-08-14ruby: Remove the RubyCache/CacheMemory latencyJoel Hestness
The RubyCache (CacheMemory) latency parameter is only used for top-level caches instantiated for Ruby coherence protocols. However, the top-level cache hit latency is assessed by the Sequencer as accesses flow through to the cache hierarchy. Further, protocol state machines should be enforcing these cache hit latencies, but RubyCaches do not expose their latency to any existng state machines through the SLICC/C++ interface. Thus, the RubyCache latency parameter is superfluous for all caches. This is confusing for users. As a step toward pushing L0/L1 cache hit latency into the top-level cache controllers, move their latencies out of the RubyCache declarations and over to their Sequencers. Eventually, these Sequencer parameters should be exposed as parameters to the top-level cache controllers, which should assess the latency. NOTE: Assessing these latencies in the cache controllers will require modifying each to eliminate instantaneous Ruby hit callbacks in transitions that finish accesses, which is likely a large undertaking.

2015-03-02mem: Move crossbar default latencies to subclassesAndreas Hansson
This patch introduces a few subclasses to the CoherentXBar and NoncoherentXBar to distinguish the different uses in the system. We use the crossbar in a wide range of places: interfacing cores to the L2, as a system interconnect, connecting I/O and peripherals, etc. Needless to say, these crossbars have very different performance, and the clock frequency alone is not enough to distinguish these scenarios. Instead of trying to capture every possible case, this patch introduces dedicated subclasses for the three primary use-cases: L2XBar, SystemXBar and IOXbar. More can be added if needed, and the defaults can be overridden.
2015-02-26Ruby: Update backing store option to propagate through to all RubyPortsJason Power

2014-11-06x86 isa: This patch attempts an implementation at mwait.Marc Orr
Mwait works as follows: 1. A cpu monitors an address of interest (monitor instruction) 2. A cpu calls mwait - this loads the cache line into that cpu's cache. 3. The cpu goes to sleep. 4. When another processor requests write permission for the line, it is evicted from the sleeping cpu's cache. This eviction is forwarded to the sleeping cpu, which then wakes up.

2014-11-06ruby: provide a backing storeNilay Vaish
Ruby's functional accesses are not guaranteed to succeed as of now. While this is not a problem for the protocols that are currently in the mainline repo, it seems that coherence protocols for gpus rely on a backing store to supply the correct data. The aim of this patch is to make this backing store configurable i.e. it comes into play only when a particular option: --access-backing-store is invoked. The backing store has been there since M5 and GEMS were integrated. The only difference is that earlier the system used to maintain the backing store and ruby's copy was write-only. Sometime last year, we moved to data being supplied supplied by ruby in SE mode simulations. And now we have patches on the reviewboard, which remove ruby's copy of memory altogether and rely completely on the system's memory to supply data. This patch adds back a SimpleMemory member to RubySystem. This member is used only if the option: access-backing-store is set to true. By default, the memory would not be accessed.
2014-11-06ruby: interface with classic memory controllerNilay Vaish
This patch is the final in the series. The whole series and this patch in particular were written with the aim of interfacing ruby's directory controller with the memory controller in the classic memory system. This is being done since ruby's memory controller has not being kept up to date with the changes going on in DRAMs. Classic's memory controller is more up to date and supports multiple different types of DRAM. This also brings classic and ruby ever more close. The patch also changes ruby's memory controller to expose the same interface.
2014-11-06ruby: single physical memory in fs modeNilay Vaish
Both ruby and the system used to maintain memory copies. With the changes carried for programmed io accesses, only one single memory is required for fs simulations. This patch sets the copy of memory that used to reside with the system to null, so that no space is allocated, but address checks can still be carried out. All the memory accesses now source and sink values to the memory maintained by ruby.

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.
2014-09-01ruby: Fixes clock domains in configuration filesEmilio Castillo ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
This patch fixes scripts related to ruby by adding the ruby clock domain. Now the L1 controllers and the Sequencer shares the cpu clock domain, while the rest of the components use the ruby clock domain. Before this patch, running simulations with the cpu clock set at 2GHz or 1GHz will output the same time results and could distort power measurements. Committed by: Nilay Vaish <nilay@cs.wisc.edu>

2014-03-20config: ruby: rename _cpu_ruby_ports to _cpu_portsNilay Vaish
2014-03-20config: remove ruby_fs.pyNilay Vaish
The patch removes the ruby_fs.py file. The functionality is being moved to fs.py. This would being ruby fs simulations in line with how ruby se simulations are started (using --ruby option). The alpha fs config functions are being combined for classing and ruby memory systems. This required renaming the piobus in ruby to iobus. So, we will have stats being renamed in the stats file for ruby fs regression.
2014-03-17config: ruby: remove piobus from protocolsNilay Vaish
This patch removes the piobus from the protocol config files. The ports are now connected to the piobus in the Ruby.py file.
2014-02-24ruby: correct errors in changeset 4eec7bdde5b0Nilay Vaish
Couple of errors were discovered in 4eec7bdde5b0 which necessitated this patch. Firstly, we create interrupt controllers in the se mode, but no piobus was being created. RubyPort, which earlier used to ignore range changes now forwards those to the piobus. The lack of piobus resulted in segmentation fault. This patch creates a piobus even in se mode. It is not created only when some tester is running. Secondly, I had missed out on modifying port connections for other coherence protocols.
2014-02-23ruby: route all packets through ruby portNilay Vaish
Currently, the interrupt controller in x86 is connected to the io bus directly. Therefore the packets between the io devices and the interrupt controller do not go through ruby. This patch changes ruby port so that these packets arrive at the ruby port first, which then routes them to their destination. Note that the patch does not make these packets go through the ruby network. That would happen in a subsequent patch.

2014-01-04ruby: add a three level MESI protocol.Nilay Vaish
The first two levels (L0, L1) are private to the core, the third level (L2)is possibly shared. The protocol supports clustered designs. For example, one can have two sets of two cores. Each core has an L0 and L1 cache. There are two L2 controllers where each set accesses only one of the L2 controllers.
