I have tried the latest versions from both the stable and dev repositories.
I am running FS mode and have tried both O3 and timing CPU. I haven't made
any changes and I am running PARSEC benchmarks. I have not made any changes
to the configuration scripts. The only minor changes I have made are those
which were required to support PARSEC.
Thanks,

Hi,
I have been trying to change cache line size (to 128) using that option.
But
I get following error
fatal: port A size 64, port B size 128
Busses don't have the same block size... Not supported.
@ cycle 0
[init:build/ALPHA_FS/mem/
bridge.cc, line 99]
I don't think just specifying the cacheline_size on command line would
work.
I have also tried setting the block size of system.tol2bus to 128 but I
still get the above error. I am not sure what I am missing.
Thanks,
Abhishek

Hi,
I am using MESI_CMP_directory protocol. I would like to change the cache
block
size in L1 cache and L2 cache to 1 word to simplify some techniques
which
I am
experimenting on.
For the Classic Memory System, configs/common/CacheConfig.py file sets
the
block
sizes of L1 and L2 caches. But I wasn't able to find the places to
modify
for
Ruby Memory System.
In src/mem/ruby/system/Cache.py, Ruby Cache class sets start_index_bit
which is
related to the cache line size. Is this the one to be modified?

There is an option for specifying the cacheline size, namely,
cacheline_size. It defaults to 64 bytes. You can set it on the command
line.

I would be really surprised if the option would not be working as this
might be one of the most basic things that anybody would like to change,
though it might be that some thing else also needs to be changed as well). I
have not used the option ever, so I would have to dig in if there is any
problem.
Can you provide the details of the gem5 version you are using and whether
or not you have made any changes?
