2011-03-28This patch supports cache flushing in MOESI_hammerSomayeh Sardashti
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.
2011-03-19configs: combine ruby_se.py and se.py to avoid all that code duplicationLisa Hsu
2011-03-19enable x86 workloads on se.pyLisa Hsu
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.
2011-02-23ARM: 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.

2011-02-07X86, Config: Move the setting of work count options to a separate function.Gabe Black
This way things that don't care about work count options and/or aren't called by something that has those command line options set up doesn't have to build a fake object to carry in inert values.

2011-02-03Mem,X86: Make the IO bridge pass APIC messages back towards the CPU.Gabe Black
2011-02-03Config: Keep track of uncached and cached ports separately.Gabe Black
This makes sure that the address ranges requested for caches and uncached ports don't conflict with each other, and that accesses which are always uncached (message signaled interrupts for instance) don't waste time passing through caches.
2011-01-19Time: Add a mechanism to prevent M5 from running faster than real time.Gabe Black
M5 skips over any simulated time where it doesn't have any work to do. When the simulation is active, the time skipped is short and the work done at any point in time is relatively substantial. If the time between events is long and/or the work to do at each event is small, it's possible for simulated time to pass faster than real time. When running a benchmark that can be good because it means the simulation will finish sooner in real time. When interacting with the real world through, for instance, a serial terminal or bridge to a real network, this can be a problem. Human or network response time could be greatly exagerated from the perspective of the simulation and make simulated events happen "too soon" from an external perspective. This change adds the capability to force the simulation to run no faster than real time. It does so by scheduling a periodic event that checks to see if its simulated period is shorter than its real period. If it is, it stalls the simulation until they're equal. This is called time syncing. A future change could add pseudo instructions which turn time syncing on and off from within the simulation. That would allow time syncing to be used for the interactive parts of a session but then turned off when running a benchmark using the m5 utility program inside a script. Time syncing would probably not happen anyway while running a benchmark because there would be plenty of work for M5 to do, but the event overhead could be avoided.

2010-08-25memtest: scale associativity and mshrs according to configSteve Reinhardt
Use the actual fanouts in the tree specification to scale cache associativity and mshrs instead of dumb constants.
2010-08-24config: changed ruby config file names to be consistentBrad Beckmann
2010-08-24config: remove ruby's requirement on the timing cmd line paramBrad Beckmann
Since ruby only works in timing mode, explicitly requiring the timing cmd line param to be specified is not necessary.

2010-08-20ruby: Reduced ruby latenciesBrad Beckmann
The previous slower ruby latencies created a mismatch between the faster M5 cpu models and the much slower ruby memory system. Specifically smp interrupts were much slower and infrequent, as well as cpus moving in and out of spin locks. The result was many cpus were idle for large periods of time. These changes fix the latency mismatch.
2010-08-20memtest: Memtester support for DMABrad Beckmann
This patch adds DMA testing to the Memtester and is inherits many changes from Polina's old tester_dma_extension patch. Since Ruby does not work in atomic mode, the atomic mode options are removed.
2010-08-20config: Improve ruby simobject namesBrad Beckmann
This patch attaches ruby objects to the system before the topology is created so that their simobject names read their meaningful variable names instead of their topology name.
2010-08-20config: reorganized how ruby specifies command-line optionsBrad Beckmann
2010-08-17sim: make Python Root object a singletonSteve Reinhardt
Enforce that the Python Root SimObject is instantiated only once. The C++ Root object already panics if more than one is created. This change avoids the need to track what the root object is, since it's available from Root.getInstance() (if it exists). It's now redundant to have the user pass the root object to functions like instantiate(), checkpoint(), and restoreCheckpoint(), so that arg is gone. Users who use configs/common/Simulate.py should not notice.

2010-03-21ruby: fixed how ruby_fs creates phsyical memoryBrad Beckmann
Now ruby_fs creates physical memory of the right size.
2010-02-27Config: Fix fs.py's call to CacheConfig.config_cache.Gabe Black
2010-02-25configs: pull out cache configuration code from se.py and fs.py.Lisa Hsu
Most of these frontend configurations share cache configuration code, pull it out so that changes to caches don't have to require changing multiple config files.
2010-02-23cache: Make caches sharing aware and add occupancy stats.Lisa Hsu
On the config end, if a shared L2 is created for the system, it is parameterized to have n sharers as defined by option.num_cpus. In addition to making the cache sharing aware so that discriminating tag policies can make use of context_ids to make decisions, I added an occupancy AverageStat and an occ % stat to each cache so that you could know which contexts are occupying how much cache on average, both in terms of blocks and percentage. Note that since devices have context_id -1, having an array of occ stats that correspond to each context_id will break here, so in FS mode I add an extra bucket for device blocks. This bucket is explicitly not added in SE mode in order to not only avoid ugliness in the stats.txt file, but to avoid broken stats (some formulas break when a bucket is 0).

2010-01-29ruby: FS support using the new configuration systemBrad Beckmann
2010-01-29ruby: reorganized ruby python configurationBrad Beckmann
Reorganized ruby python configuration so that protocol and ruby memory system configuration code can be shared by multiple front-end configuration files (i.e. memory tester, full system, and hopefully the regression tester). This code works for memory tester, but have not tested fs mode.
2010-01-29ruby: Memory Controller Profiler with new config systemBrad Beckmann
This patch includes a rather substantial change to the memory controller profiler in order to work with the new configuration system. Most noteably, the mem_cntrl_profiler no longer uses a string map, but instead a vector. Eventually this support should be removed from the main profiler and go into a separate object. Each memory controller should have a pointer to that new mem_cntrl profile object.
2010-01-29ruby: Converted MOESI_hammer dma cntrl to new config systemBrad Beckmann
2010-01-29ruby: Added the cache profiler to the new config systemBrad Beckmann
2010-01-29ruby: Added clock to ruby systemBrad Beckmann
As a first step to migrate ruby to the M5 eventqueue, added a clock variable to the ruby system.
2010-01-29ruby: Ruby changes required to use the python config systemBrad Beckmann
This patch includes the necessary changes to connect ruby objects using the python configuration system. Mainly it consists of removing unnecessary ruby object pointers and connecting the necessary object pointers using the generated param objects. This patch includes the slicc changes necessary to connect generated ruby objects together using the python configuraiton system.

2010-01-29ruby: Add support for generating topologies in Python.Steve Reinhardt
2010-01-29ruby: Convert most Ruby objects to M5 SimObjects.Steve Reinhardt
The necessary companion conversion of Ruby objects generated by SLICC are converted to M5 SimObjects in the following patch, so this patch alone does not compile. Conversion of Garnet network models is also handled in a separate patch; that code is temporarily disabled from compiling to allow testing of interim code.
2009-11-18m5: improvements to the ruby_fs.py fileBrad Beckmann
2009-11-18ruby: included ruby config parameter ports per coreBrad Beckmann
Slightly improved the major hack need to correctly assign the number of ports per core. CPUs have two ports: icache + dcache. MemTester has one port.
2009-11-18ruby: Support for merging ALPHA_FS and rubyBrad Beckmann
Connects M5 cpu and dma ports directly to ruby sequencers and dma sequencers. Rubymem also includes a pio port so that pio requests and be forwarded to a special pio bus connecting to device pio ports.
