Hi Gabriel,

 

I have 4 patches in the gem5 review board.  You can apply them if you want a
cache bank model (classic cache model only, not ruby).

 

Best,

Xiangyu

I would rather argue that it only supports "infinite" bank caches as it does
not model the contention to the RAMs.

Classic model does not support multi-bank caches. I don't know about Ruby.

Specifically for ARM L1/L2 caches using the default memory, e.g.: 

 

./build/ARM/gem5.fast ... configs/example/fs.py ...  --caches
--cpu-type=detailed --l1d_size=32kB --l1i_size=32kB --l2cache
--l2_size=2048kB --clock=0.75GHz


 

How is each cache configured in terms of banks? Is each the L1d, L1i and L2
cache a single memory bank by default?

 

I've looked through the gem5/ directory but couldn't find any mention of
bank configurations except for specific memory protocols or for DRAM. And
couldn't find any mention of this elsewhere.

 

Thank you,

Gabriel
