2012-01-11Ruby: Use map option for selecting b/w sparse and memory vectorNilay Vaish
2012-01-11Config: Add support for restoring using a timing CPUNilay Vaish
Currently there is an assumption that restoration from a checkpoint will happen by first restoring to an atomic CPU and then switching to a timing CPU. This patch adds support for directly restoring to a timing CPU. It adds a new option '--restore-with-cpu' which is used to specify the type of CPU to which the checkpoint should be restored to. It defaults to 'atomic' which was the case before.
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The Ruby Tracer is out of date with the changes that are being carried out to support checkpointing.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.

2012-01-05Config: Add an option of type 'choice' for cpu typeNilay Vaish
This patch adds a new option for cpu type. This option is of type 'choice' which is similar to a C++ enum, except that it takes string values as possible choices. Following options are being removed -- detailed, timing, inorder. --HG-- extra : rebase_source : 58885e2e8a88b6af8e6ff884a5922059dbb1a6cb

2011-12-01VNC: Add support for capturing frame buffer to file each time it is changed.Chris Emmons
When a change in the frame buffer from the VNC server is detected, the new frame is stored out to the m5out/frames_*/ directory. Specifiy the flag "--frame-capture" when running configs/example/fs.py to enable this behavior. --HG-- extra : rebase_source : d4e08e83f4fa6ff79f3dc9c433fc1f0487e057fc
2011-12-01O3: Remove hardcoded tgts_per_mshr in O3CPU.py.Chander Sudanthi
There are two lines in O3CPU.py that set the dcache and icache tgts_per_mshr to 20, ignoring any pre-configured value of tgts_per_mshr. This patch removes these hardcoded lines from O3CPU.py and sets the default L1 cache mshr targets to 20. --HG-- extra : rebase_source : 6f92d950e90496a3102967442814e97dc84db08b
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.

2011-08-02Scons: Drop RUBY as compile time option.Nilay Vaish
This patch drops RUBY as a compile time option. Instead the PROTOCOL option is used to figure out whether or not to build Ruby. If the specified protocol is 'None', then Ruby is not compiled.
2011-07-26Ruby: Fix instantiations of DMA controller and sequencerNilay Vaish
The patch on Ruby functional accesses made changes to the process of instantiating controllers and sequencers. The DMA controller and sequencer was not updated, hence this patch.
2011-07-25Ruby: Fix dma controller configs/ruby/MI_example.pyNilay Vaish
The dma controller in configs/ruby/MI_example.py was not being set correctly. This patch fixes it.
2011-07-11se.py: Fixes the way ruby's options are addedNilay Vaish
2011-07-03Network_test: Conform it with functional access changes in RubyNilay Vaish
Addition of functional access support to Ruby necessitated some changes to the way coherence protocols are written. I had forgotten to update the Network_test protocol. This patch makes those updates.
2011-06-30config: removed unnecessary slashesBrad Beckmann
This patch removes unnecessary slashes from a couple of python scripts.
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: revamp x86 config to avoid appending to SimObjectVectorsSteve Reinhardt
A significant contributor to the need for adoptOrphanParams() is the practice of appending to SimObjectVectors which have already been assigned as children. This practice sidesteps the assignment operation for those appended SimObjects, which is where parent/child relationships are typically established. This patch reworks the config scripts that use append() on SimObjectVectors, which all happen to be in the x86 system configuration. At some point in the future, I hope to make SimObjectVectors immutable (by deriving from tuple rather than list), at which time this patch will be necessary for correct operation. For now, it just avoids some of the warning messages that get printed in adoptOrphanParams().
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.

2011-05-21configs: remove -p from ruby_network_test.pyTushar Krishna
A recent patch broke the ruby network tester by adding -p inside Options.py which conflicts with the -p inside ruby_network_test.py. Have removed -p from ruby_network_test.py
2011-05-20configs: cleanup redundant/unused optionsKorey Sewell
maxinsts & max_inst redundant prog_intvl and profile seem redundant, but profile looks to be unused add -p option for progress intervals
2011-05-07NetworkTest: added sim_cycles parameter to the network tester.Tushar Krishna
The network tester terminates after injecting for sim_cycles (default=1000), instead of having to explicitly pass --maxticks from the command line as before. If fixed_pkts is enabled, the tester only injects maxpackets number of packets, else it keeps injecting till sim_cycles. The tester also works with zero command line arguments now.

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

This patch moves the assignment of testsys.switch_cpus, testsys.switch_cpus_1, switch_cpu_list, and switch_cpu_list1 outside of the for loop so they are assigned only once, after switch_cpus and switch_cpus_1 are constructed.

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.

2011-03-19se.py: Modify script to make multiprogramming much easier.Lisa Hsu
Now, instead of --bench benchname, you can do --bench bench1-bench2-bench3 and it will set up a simulation that instantiates those three workloads. Only caveat is that now, for sanity checking, your -n X must match the number of benches in the list.
2011-03-17ARM: Bare metal system should have 256MB of RAM.Ali Saidi
2011-03-17Mem: Fix issue with dirty block being lost when entire block transferred to ↵Ali Saidi
non-cache. This change fixes the problem for all the cases we actively use. If you want to try more creative I/O device attachments (E.g. sharing an L2), this won't work. You would need another level of caching between the I/O device and the cache (which you actually need anyway with our current code to make sure writes propagate). This is required so that you can mark the cache in between as top level and it won't try to send ownership of a block to the I/O device. Asserts have been added that should catch any issues.

env was being implicitly imported into Benchmarks.py through SysPaths.py. This change brings it in explicitly in the file where it's used.
2011-02-23ARM: Clarifies creation of Linux and baremetal ARM systems.Ali Saidi
makeArmSystem creates both bare-metal and Linux systems more cleanly. machine_type was never optional though listed as an optional argument; a system such as "RealView_PBX" must now be explicitly specified. Now that it is a required argument, the placement of the arguments has changed slightly requiring some changes to calls that create ARM systems.
