[gem5-users] Re: GEM5/Ruby
Hi Javed, Unfortunately, there's no protocols in gem5 out of the box that model *exactly* what you need. However, SLICC allows you to write your own protocols! It sounds like that is what would be best if you need such a specific coherence protocol. See http://www.gem5.org/documentation/general_docs/ruby/slicc/ and http://www.gem5.org/documentation/learning_gem5/part3/MSIintro/ for more information.

[gem5-users] Re: Problem compiling gem5 with Ubuntu 20.04
Hi Sam,
This is a temporary issue with python3 support. Once gem5-20 is released
(hopefully today or tomorrow), this issue should be resolved. In the
meantime, you can try to downgrade to python 2 and run `python2 scons`
or use an ubuntu 18.04 docker image (see
http://www.gem5.org/documentation/general_docs/building#docker for
details.).
Cheers,
Jason

[gem5-users] Problem compiling gem5 with Ubuntu 20.04
Dear All,
I got a problem compiling gem5 latest repo on Ubuntu 20.04.
It gives following error:
scons build/X86/gem5.opt -j6
scons: Reading SConscript files ...
Warning: Failed to find git repo directory: a bytes-like object is
required, not 'str'
TypeError: argument should be integer or bytes-like object, not 'str':
File "/home/samsi/gem5/SConstruct", line 355:
main['GCC'] = CXX_version and CXX_version.find('g++') >= 0
Any ideas how to fix this error?
Thanks in advance.
Sam

[gem5-users] GEM5/Ruby
Hello I would like to define a multicore system in GEM5 and then use the Ruby memory system to simulate the different coherence protocols. In my system I have three levels of caches (L1I$, L1D$ (using MSI), unified L2$ (using MOESI) and LLC (using MESI)) How to generate the optimised GEM5 executable simulator to handle the three different coherence protocol in the system? Thanks in advance JO ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s

Maybe you want to look into: m5 readfile, 9P or use two disks as mentioned at: https://cirosantilli.com/linux-kernel-module-cheat/#gem5-restore-new-script On Sun, May 17, 2020 at 9:20 PM HENG ZHUO via gem5-users wrote: > > Hi, > > I am trying to run some benchmark on ARM full system simulation.
