2017-12-04misc: Rename misc.(hh|cc) to logging.(hh|cc)Gabe Black
These files aren't a collection of miscellaneous stuff, they're the definition of the Logger interface, and a few utility macros for calling into that interface (panic, warn, etc.).

2015-09-05ruby: set: reimplement using std::bitsetNilay Vaish
The current Set data structure is slow and therefore is being reimplemented using std::bitset. A maximum limit of 64 is being set on the number of controllers of each type. This means that for simulating a system with more controllers of a given type, one would need to change the value of the variable NUMBER_BITS_PER_SET

2014-09-03base: Use the global Mersenne twister throughoutAndreas Hansson
This patch tidies up random number generation to ensure that it is done consistently throughout the code base. In essence this involves a clean-up of Ruby, and some code simplifications in the traffic generator. As part of this patch a bunch of skewed distributions (off-by-one etc) have been fixed. Note that a single global random number generator is used, and that the object instantiation order will impact the behaviour (the sequence of numbers will be unaffected, but if module A calles random before module B then they would obviously see a different outcome). The dependency on the instantiation order is true in any case due to the execution-model of gem5, so we leave it as is. Also note that the global ranom generator is not thread safe at this point. Regressions using the memtest, TrafficGen or any Ruby tester are affected and will be updated accordingly.
2012-01-06Ruby Set: Move NUMBER_WORDS_PER_SET to Set.hhNilay Vaish
This constant is currently in System.hh, but is only used in Set.hh. It is being moved to Set.hh to remove this artificial dependence of Set.hh on System.hh. --HG-- extra : rebase_source : 683c43a5eeaec4f5f523b3ea32953a07f65cfee7
2011-11-03Ruby: Remove some unused typedefsNilay Vaish
This patch removes some of the unused typedefs. It also moves some of the typedefs from Global.hh to TypeDefines.hh. The patch also eliminates the file NodeID.hh.
2011-06-14Ruby: Correct set LONG_BITS and INDEX_SHIFT in class Set.Nilay Vaish
The code for Set class was written under the assumption that std::numeric_limits<long>::digits returns the number of bits used for data type long, which was presumed to be either 32 or 64. But return value is actually one less, that is, it is either 31 or 63. The value is now being incremented by 1 so as to correctly set it.

2010-06-01style: clean up ruby's Set classNathan Binkert
Further cleanup should probably be done to make this class be non-Ruby specific and put it in src/base. There are probably several cases where this class is used, std::bitset could be used instead.
2010-04-02ruby: get "using namespace" out of headersNathan Binkert
In addition to obvious changes, this required a slight change to the slicc grammar to allow types with :: in them. Otherwise slicc barfs on std::string which we need for the headers that slicc generates.

2009-05-11ruby: decommission codePolina Dudnik
1. Set.* and BigSet.* are replaced with OptBigSet.* which was renamed Set.* 2. Decomissioned all bloom filters 3. Decomissioned ruby/simics directory
2009-05-11ruby: Make ruby #includes use full paths to the files they're including.Nathan Binkert
This basically means changing all #include statements and changing autogenerated code so that it generates the correct paths. Because slicc generates #includes, I had to hard code the include paths to mem/protocol.
2009-05-11ruby: Import ruby and slicc from GEMSNathan Binkert
We eventually plan to replace the m5 cache hierarchy with the GEMS hierarchy, but for now we will make both live alongside eachother.
