Re: [gem5-users] Errors building on Ubuntu 17.10

Hi to all in this discussion, I wanted to add some points to the discussion above regarding ARM+ RUBY. I have been working with ARM +RUBY and I have simulated 2x2/ 4x4 Mesh_XY NoC with MESI_Two_Level protocol. This protocol works fine with ARM in full system mode. But originally MESI_Two_Level

Re: [gem5-users] Errors building on Ubuntu 17.10

Hi Paul, It's in my brain, why don't other know this automatically ;). ARM works well with all of the CPU models and the classic caches. There are limited cases where ARM works with Ruby. To find out what ARM+Ruby is supported I would look back through the commit log to see which protocols have

Hi Jason, Hmm, do you have a sense for which (just a small subset is fine) combinations are a good idea to run and/or which aren't :-). Paul On Fri, Feb 23, 2018 at 5:09 PM, Jason Lowe-Power wrote: > Hi Paul, > > Yeah, the status matrix is very out of date. I would like to

Re: [gem5-users] Errors building on Ubuntu 17.10

Hi Paul, Yeah, the status matrix is very out of date. I would like to see it automatically updated by our regression tests / continuous integration tests. However, those are also wildly out of date. It would be *fabulous* if someone had time / money / energy to revamp our testing infrastructure

Re: [gem5-users] Errors building on Ubuntu 17.10

Hey Jason, Sure no problem, my guess is that the uninitialized warning/error is ARM specific (its in some neon memory file) so maybe that's why it fell through? BTW, on a similar note, I see that the gem5 status matrix ( http://gem5.org/Status_Matrix) hasn't been updated in a number of years, is

Re: [gem5-users] Errors building on Ubuntu 17.10

Thanks Ciro! yeah I saw that patch right after I posted. Haven't tried it out yet though as I got it to work by adding those two hacks to the SConfigure file. I'd probably prefer not to do the gcc rollback since part of what I'm doing is getting this up and running for some lab assignments I

Re: [gem5-users] Errors building on Ubuntu 17.10

Hi Paul, Thanks for letting us know. There's currently a patch on our review site that solves the implicit fallthrough problem ( https://gem5-review.googlesource.com/c/public/gem5/+/8541). I haven't seen the uninitialized warning, though. Cheers, Jason --- Jason Lowe-Power Assistant

Re: [gem5-users] Errors building on Ubuntu 17.10

I reproduce. There was already a patch to port to 7.2.0 at 5c41076bd7610d03431fd0dd89bd0fdc7f30d6bd but the migration wasn't complete. One workaround that does not require modifying the code is: sudo apt-get install g++-6 gcc-6 CC=gcc-6 CXX=g++-6 scons
