Subject: Re: [gem5-users] Arrays in SLICC
That is exactly what I need. The only issue I have right now is that I need to
create a structure that contains an array. I can make the array by using a
std::vector type in an external C++ file, but I then need to assign each index
in the array with one of the L1 caches attached to the L2 cache in order for it
the code to know where to send messages if needed. I don't know how to get this
done.
In my custom topology I can easily figure out the L1 caches that belong to a L2
cache so I am thinking that I may able to override the standard initialization
method (of the L2 cache) with a special one that takes all the L1 caches and
assigns each L1 cache to a value in the array. I don't know if this will work
though.

Alex,
I am not sure I understand your confusion.
All of the current external structures are written in C++ and exposed to SLICC
via that RubySlicc_Types.sm file. You can
1) declare/define your custom C++ Class, place it either in /ruby/system or
/ruby/structures
2) Modify the corresponding Sconscript to include your new files
3) Be sure to add MakeInclude(CustomClass) in /ruby/Sconscript
4) modify RubySlicc_Types.sm accordingly
5) Instantiate an instance of your custom class at the top of whichever .sm
file you want to use it (e.g. see prefetcher
instantiation of MESI_CMP_directory, or even how L1I/L1D, Sequencers are
instantiated.
