2019-10-11mem-ruby: Allow Ruby to use all replacement policies in ClassicJingQuJQ
Add support in Ruby to use all replacement policies in Classic. Furthermore, if new replacement policies are added to the Classic system, the Ruby system will recognize new policies without any other changes in Ruby system. The following list all the major changes: * Make Ruby cache entries (AbstractCacheEntry) inherit from Classic cache entries (ReplaceableEntry). By doing this, replacement policies can use cache entries from Ruby caches. AccessPermission and print function are moved from AbstractEntry to AbstractCacheEntry, so AbstractEntry is no longer needed. * DirectoryMemory and all SLICC files are changed to use AbstractCacheEntry as their cache entry interface. So do the python files in mem/slicc/ast which check the entry interface. * "main='false'" argument is added to the protocol files where the DirectoryEntry is defined. This change helps differentiate DirectoryEntry from CacheEntry because they are both the instances of AbstractCacheEntry now. * Use BaseReplacementPolicy in Ruby caches instead of AbstractReplacementPolicy so that Ruby caches will recognize the replacement policies from Classic. * Add getLastAccess() and useOccupancy() function to Classic system so that Ruby caches can use them. Move lastTouchTick to ReplacementData struct because it's needed by getLastAccess() to return the correct value. * Add a 2-dimensional array of ReplacementData in Ruby caches to store information for different replacement policies. Note that, unlike Classic caches, where policy information is stored in cache entries, the policy information needs to be stored in a new 2-dimensional array. This is due to Ruby caches deleting the cache entry every time the corresponding cache line get evicted.

2019-09-10mem-ruby: Move Bloom Filters to baseDaniel R. Carvalho
All Bloom Filters are completely independent of Ruby, and therefore can be used everywhere. As a side effect, Ruby was not using the filters, so their dependency was removed.

2019-08-23mem: Move ruby protocols into a directory called ruby_protocol.Gabe Black
Now that the gem5 protocols are split out, it would be nice to put them in their own protocol directory. It's also confusing to have files called *_protocol which are not in the protocol directory.

It makes no sense to include these files into the build when there will be no protocol to utilize them.

2018-03-06scons: Switch from the print statement to the print function.Gabe Black
Starting with version 3, scons imposes using the print function instead of the print statement in code it processes. To get things building again, this change moves all python code within gem5 to use the function version. Another change by another author separately made this same change to the site_tools and site_init.py files.

This patch drops the NetworkMessage class. The relevant data members and functions have been moved to the Message class, which was the parent of NetworkMessage.
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.
2014-09-01build opts: add MI_example to NULL ISANilay Vaish
A later changeset changes the file src/python/swig/pyobject.cc to include a header file that includes a header file generated at build time depending on the PROTOCOL in use. Since NULL ISA was not specifying any protocol, this resulted in compilation problems. Hence, the changeset.
2014-09-01ruby: move files from ruby/system to ruby/structuresNilay Vaish
The directory ruby/system is crowded and unorganized. Hence, the files the hold actual physical structures, are being moved to the directory ruby/structures.

2013-09-04arch: Resurrect the NOISA build target and rename it NULLAndreas Hansson
This patch makes it possible to once again build gem5 without any ISA. The main purpose is to enable work around the interconnect and memory system without having to build any CPU models or device models. The regress script is updated to include the NULL ISA target. Currently no regressions make use of it, but all the testers could (and perhaps should) transition to it. --HG-- rename : build_opts/NOISA => build_opts/NULL rename : src/arch/noisa/SConsopts => src/arch/null/SConsopts rename : src/arch/noisa/cpu_dummy.hh => src/arch/null/cpu_dummy.hh rename : src/cpu/intr_control.cc => src/cpu/intr_control_noisa.cc
2012-12-11ruby: add a prefetcherNilay Vaish
This patch adds a prefetcher for the ruby memory system. The prefetcher is based on a prefetcher implemented by others (well, I don't know who wrote the original). The prefetcher does stride-based prefetching, both unit and non-unit. It obseves the misses in the cache and trains on these. After the training period is over, the prefetcher starts issuing prefetch requests to the controller.

2011-08-02Scons: Make some Action objects fit the abreviated output format.Gabe Black
2011-03-31Ruby: Add new object called WireBuffer to mimic a Wire.Lisa Hsu
This is a substitute for MessageBuffers between controllers where you don't want messages to actually go through the Network, because requests/responses can always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered) because you are, after all, going through a network with contention. For systems where you model multiple controllers that are very tightly coupled and do not actually go through a network, it is a pain to have to write a coherence protocol to account for mixed up request/response orderings despite the fact that it's completely unrealistic. This is *not* meant as a substitute for real MessageBuffers when messages do in fact go over a network.

2010-01-29ruby: Convert most Ruby objects to M5 SimObjects.Steve Reinhardt

2009-05-11ruby: Migrate all of ruby and slicc to SCons.Nathan Binkert
Add the PROTOCOL sticky option sets the coherence protocol that slicc will parse and therefore ruby will use. This whole process was made difficult by the fact that the set of files that are output by slicc are not easily known ahead of time. The easiest thing wound up being to write a parser for slicc that would tell me. Incidentally this means we now have a slicc grammar written in python.
