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.
2011-03-17ARM: 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.
2011-02-24Configs: Explicitly import env in Benchmarks.pyGabe Black
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.
2011-02-23configs: cache: add cache line size optionKorey Sewell
2011-02-23configs: set default cache paramsKorey Sewell
It's confusing (especially to new users), when you are setting some standard parameters (as defined in Options.py) and they aren't reflected in the simulations so we might as well link the settings in CacheConfig.py to those in Options.py
2011-02-11VNC: Add VNC server to M5Ali Saidi
2011-02-08memtest: due to contention increase, increased deadlock thresholdBrad Beckmann
2011-02-08config: fixed minor bug connecting dma devices to rubyBrad Beckmann
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.
2011-02-06boot: script that creates a checkpoint after Linux boot upBrad Beckmann

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.
2011-02-02X86: Change how the default disk image gets set up.Gabe Black
The disk image to use was always being forced to a particular value. This change changes what disk image is selected as the default based on the architecture being built. In the future, a more sophisticated system might be used that selected a path based on certain rules instead of relying on one off file names.
2011-02-01X86: Add L1 caches for the TLB walkers.Gabe Black
Small L1 caches are connected to the TLB walkers when caches are used. This allows them to participate in the coherence protocol properly.
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.

2011-01-03Ruby: Add option for random seed to Ruby.pyNilay Vaish
This patch adds an option to the script Ruby.py for setting the parameter m_random_seed used for randomizing delays in the memory system. The option can be specified as "--random_seed <seed value>".
2010-12-07Configs: Automatically choose the correct hello world binary.Ali Saidi
2010-11-17Config: Change misleading "cycle" message to say "tick".Gabe Black
Most of the messages in the config scripts that report a time value already print "@ tick" followed by the current tick value, but a few were printing "@ cycle". Since this is a distinction that's frequently confusing to new users, this changes those message to the more accurate and consistent "@ tick".
2010-11-15ARM: Add support for a dumb IDE controllerAli Saidi
2010-11-08Mem: Finish half-baked support for mmaping file in physmem.Ali Saidi
Physmem has a parameter to be able to mem map a file, however it isn't actually used. This changeset utilizes the parameter so a file can be mmapped.
2010-10-22Configs: Stop setting the "mem" parameter in splash2 config files.Gabe Black
This parameter is no longer used, and trying to set it like these scripts were gives a simobject two parents and causes the simulation to die.

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: Recycle latency fix for hammerBrad Beckmann
Patch allows each individual message buffer to have different recycle latencies and allows the overall recycle latency to be specified at the cmd line. The patch also adds profiling info to make sure no one processor's requests are recycled too much.

This fix includes the off-by-one bit selection bug for numa mapping.
2010-08-20ruby: Disable migratory sharing for token and hammerBrad Beckmann
This patch allows one to disable migratory sharing for those cache blocks that are accessed by atomic requests. While the implementations are different between the token and hammer protocols, the motivation is the same. For Alpha, LLSC semantics expect that normal loads do not unlock cache blocks that have been locked by LL accesses. Therefore, locked blocks should not transfer write permissions when responding to these load requests. Instead, only they only transfer read permissions so that the subsequent SC access can possibly succeed.
