2010-08-23ARM: Add configuration for Linux/Full SystemAli Saidi
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.
2010-08-20ruby: added probe filter support to hammerBrad Beckmann
2010-08-20ruby: fixed DirectoryMemory's numa_high_bit configurationBrad Beckmann
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.
2010-08-20ruby: Improved try except blocks in ruby creationBrad Beckmann
Replaced the sys.exit in the try-except blocks with raise so that the python call stack will be printed
2010-08-20config: added cmd options to control ruby debugBrad Beckmann
2010-08-20ruby: Resurrected Ruby's deterministic testsBrad Beckmann
Added the request series and invalidate deterministic tests as new cpu models and removed the no longer needed ruby tests --HG-- rename : configs/example/rubytest.py => configs/example/determ_test.py rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/DirectedGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/DirectedGenerator.hh rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/InvalidateGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/InvalidateGenerator.hh rename : src/cpu/rubytest/RubyTester.cc => src/cpu/directedtest/RubyDirectedTester.cc rename : src/cpu/rubytest/RubyTester.hh => src/cpu/directedtest/RubyDirectedTester.hh rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/SeriesRequestGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/SeriesRequestGenerator.hh
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.
2010-08-20ruby: added token broadcast config params to cmd optionsBrad Beckmann
2010-08-20config: reorganized how ruby specifies command-line optionsBrad Beckmann
2010-08-20config: moved python protocol config filesBrad Beckmann
Moved the python protocol config files back to their original location to avoid addToPath calls. --HG-- rename : configs/ruby/protocols/MESI_CMP_directory.py => configs/ruby/MESI_CMP_directory.py rename : configs/ruby/protocols/MI_example.py => configs/ruby/MI_example.py rename : configs/ruby/protocols/MOESI_CMP_directory.py => configs/ruby/MOESI_CMP_directory.py rename : configs/ruby/protocols/MOESI_CMP_token.py => configs/ruby/MOESI_CMP_token.py rename : configs/ruby/protocols/MOESI_hammer.py => configs/ruby/MOESI_hammer.py
2010-08-17misc: add some AMD copyright noticesSteve Reinhardt
Meant to add these with the previous batch of csets.
2010-08-17sim: fold checkpoint restore code into instantiate()Steve Reinhardt
The separate restoreCheckpoint() call is gone; just pass the checkpoint dir as an optional arg to instantiate(). This change is a precursor to some more extensive reworking of the startup code.
2010-08-17configs: clean up checkpoint code in Simulation.pySteve Reinhardt
Small change to clean up some redundant code. Should not have any functional impact.
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.

2010-07-05util: add a script for testing checkpointingSteve Reinhardt
See comments in util/checkpoint-tester.py for details.

2010-03-21added sparse memory support to hammerBrad Beckmann
2010-03-21ruby: Adds configurable bit selection for numa mappingBrad Beckmann
2010-03-21ruby: Ruby support for sparse memoryBrad Beckmann
The patch includes direct support for the MI example protocol.
2010-03-21ruby: removed ruby.config from configs/exampleBrad Beckmann
2010-03-21ruby: Python config files now sets a unique id for each sequencerBrad Beckmann
2010-03-21ruby: fixed how ruby_fs creates phsyical memoryBrad Beckmann
Now ruby_fs creates physical memory of the right size.
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.
2010-02-27Config: 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: ruby_se.py updated to new config systemBrad Beckmann
2010-01-29ruby: Removed if else statement in create_systemBrad Beckmann
Based on Steve's suggestion, the ugly if-elif statement and multiple protocol module import calls are removed and replaced with exec statements using the protocol string.
2010-01-29ruby: memtest-ruby updated to the new config systemBrad Beckmann
2010-01-29ruby: Converted Garnet to M5 configurationBrad Beckmann
2010-01-29ruby: Added a mesh topologyBrad Beckmann
2010-01-29ruby: MESI_CMP_directory updated to the new config systemBrad Beckmann
2010-01-29ruby: MOESI_CMP_directory updated to the new config systemBrad Beckmann
2010-01-29ruby: MOESI_CMP_token updates to use the new config systemBrad Beckmann
2010-01-29ruby: MI_example updates to use the new config systemBrad Beckmann
2010-01-29ruby: Memory size consistency checkBrad Beckmann
Ruby's memory is now sized according to the size of M5 physical memory.
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: added the GEMS ruby testerBrad Beckmann
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.
2010-01-29ruby: Removed RubySystem::getNumberOfSequencersBrad Beckmann
removed the static function RubySystem::getNumberOfSequencers and replaced it with a python config variable
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.
