Allow the number of controllers of an specific type to incremented externally. This enables a custom implementation of AbstractController to pose as an specific SLICC-generated machine. See subsequent patches for examples. Change-Id: I0b9a3fc82439c18156e377363cebc0385b47f1cd

This snoop reponse is not generated internally by the SLICC implementation, but is required for compatibility with classic caches which may remain in SD state while returning SC data upon receiving a converted SnpShared. Change-Id: I5270b29c8863c7afd8abc39b3c7978b95330c183

Component implementing a generic controller that allow classic caches interaction with Ruby/CHI. The CHIGenericController provides an interface to send/receive CHI messages to/from the interconnect. This is implement in C++ rather then SLICC. This controller is seen as a MachineType:Cache by the CHI implementation in SLICC. Change-Id: I3afc4363f4290095c2f7428c8487bccd932e0300
This commit allows top level configs making use of the Ruby module to define node generation callbacks. The config_ruby function will check the system object for two factory methods 1) _rnf_gen, if defined, will be called to generate RNFs 2) _mn_gen, if defined, will be called to generate MNs Change-Id: I9daeece646e7cdb2d3bfefa761a9650562f8eb4b Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com>

Would you be willing to talk about this in the next gem5-dev meeting? This is super cool! |
Will it be on the 9th of May? If that's the case I won't be able to attend it, though @tiagormk (who's the author of these changes/feature) might be |

Yes, it will be on May 9th at 4pm UTC. @tiagormk, would you be available to attend and discuss this improvement? |
Unfortunately I have a conflict that time. But I could join the June meeting probably. |

This PR is mainly adding a CHIGenericController class to model a coherence controller entirely
in C++ to work with ruby. This is a stepping stone towards supporting a hybrid setup with
classic caches + ruby.
