Hi Javed, You are correct in your assumptions. I believe the confusion arises from the overuse of the "System" keyword. As a summary, The System class (defined in src/sim/system.hh) is the child of the Root node and encompasses most of the simulated models (cpu, memory subsystem, devices, etc).
The RubySystem is a child of the System class (system.ruby = RubySystem() adds the RubySystem to the SimObject hierarchy under the system node). In other words, the RubySystem is a subsystem, whose only purpose is to parent ruby memory models. It is not a replacement for the System class nor a different implementation Kind regards Giacomo > -----Original Message----- > From: Javed Osmany via gem5-users <gem5-users@gem5.org> > Sent: 16 June 2021 11:17 > To: gem5 users mailing list <gem5-users@gem5.org> > Cc: Javed Osmany <javed.osm...@huawei.com> > Subject: [gem5-users] FW: System() and RubySystem() > > Hello > > > > Wondering if any help to clear up the issues listed in my previous email? > > > > Tks > > JO > > > > From: Javed Osmany > Sent: 14 June 2021 14:18 > To: gem5 users mailing list <gem5-users@gem5.org> > Cc: Javed Osmany <javed.osm...@huawei.com> > Subject: System() and RubySystem() > > > > Hello > > > > Trying to understand the following: > > > > So in example config scripts I see the following: > > > > system = System() // Is this then instantiating the default overall > system ?? > > > > Now, I understand that there are two types of memory system, namely > classic and Ruby. > > > > And then if "-ruby" is specified on the command line, the script Ruby.py is > called. > > Within Ruby.py, the function creat_system() is called and in Ruby.py (lines > 193 - 194), we have the code > > > > system.ruby = Ruby.System() // Is this then instantiating the Ruby > memory system within the overall System() ?? > > ruby = system.ruby // This is then just an alias ?? > > > > > > Thanks in advance. > > J.Osmany IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
