Hi Arun, I tested gem5_19 with classic cache x86 with O3CPU, both smt and multicore simulations are working Best regards, Abhishek On Mon, Mar 2, 2020 at 12:34 AM Arun Kavumkal wrote: > Hi Ciro > I was debugging the X86, mutlticore issue as suggested by you. > I could see that the simulation exits as expected by changing > * if (activeContexts ==0)* > at > https://github.com/gem5/gem5/blob/9fc9c67b4242c03f165951775be5cd0812f2a705/src/sim/syscall_emul.cc#L212 > to *if (activeContexts == 1).* > This change is done as per the commit > https://github.com/gem5/gem5/commit/bae0edb0d26dc6c4738855cf38e9a6a109ae8003 > I want to ask, whether this change ie *if (activeContexts ==0) *was a > bug or intentional for some other reason? > > Thanks > KP Arun > > On Tue, Feb 18, 2020 at 11:45 PM Abhishek Singh < > abhishek.singh199...@gmail.com> wrote: > >> Hi, >> >> A ticket is already opened about this at Jira >> https://gem5.atlassian.net/projects/GEM5/issues >> >> Arun: This repo (https://gem5.googlesource.com/amd/gem5/) will solve >> your problem >> >> >> On Tue, Feb 18, 2020 at 1:06 PM Ciro Santilli >> wrote: >> >>> Hi Arun, >>> >>> "I started using ruby memory model after reading from gem5 email >>> archive that classic memory does not work with multicore DerivO3CPU.": >>> I didn't know this, where was this mentioned?

Re: [gem5-users] Simulation does not stop, SE mode, 2 cpus, DerivO3CPU, ruby memory
Hi Ciro I was debugging the X86, mutlticore issue as suggested by you. I could see that the simulation exits as expected by changing * if (activeContexts ==0)* at https://github.com/gem5/gem5/blob/9fc9c67b4242c03f165951775be5cd0812f2a705/src/sim/syscall_emul.cc#L212 to *if (activeContexts == 1).* This change is done as per the commit https://github.com/gem5/gem5/commit/bae0edb0d26dc6c4738855cf38e9a6a109ae8003 I want to ask, whether this change ie *if (activeContexts ==0) *was a bug or intentional for some other reason?

Hi Arun, "I started using ruby memory model after reading from gem5 email archive that classic memory does not work with multicore DerivO3CPU.": I didn't know this, where was this mentioned? I have just run an ARM pthread hello world on DerivO3CPU 2 cores and it worked on master. I reproduce your problem on X86 DerivO3CPU classic but not ARM DerivO3CPU.

[gem5-users] Simulation does not stop, SE mode, 2 cpus, DerivO3CPU, ruby memory
Hi, I am trying to run gem5 in SE mode with number of cpus 2, cpu type DerivO3CPU, and ruby memory model using following command, but the simulation does not stop even after results are produced , ie *"Hello world!"* is printed to stdout *build/X86_MESI_Three_Level/gem5.opt configs/example/se.py -n 2 --ruby --cpu-type=DerivO3CPU -c 'tests/test-progs/hello/bin/x86/linux/hello;tests/test-progs/hello/bin/x86/linux/hello' * I started using ruby memory model after reading from gem5 email archive that classic memory does not work with multicore DerivO3CPU.
