No problem, I provided that mainly as a working baseline, so now you can diff out the working setup with yours to find the problem more easily :-) Also consider the docker setup if you are having installation difficulties: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/36cffd5c1a6e081194610d1d77a43a863f1d1157#docker > My gem5 version is a mercurial directory. > This the summary I get > > parent: 11775:0eadb0b6e9de tip > > > Best > Gagan > -----Original Message----- > From: gem5-users [mailto:gem5-users-boun...@gem5.org] On Behalf Of Ciro > Santilli > Sent: Tuesday, 17 April 2018 14:41 > To: gem5 users mailing list <gem5-users@gem5.org> > Subject: Re: [gem5-users] Multi-threading on ARM timing CPU > > On Tue, Apr 17, 2018 at 10:15 AM, Singh, G. <g.si...@tue.nl> wrote: >> Hi, >> >> Please find enclosed the script file and the program code for matrix >> multiplication which I tried. >> > > Thanks. > > Which disk image / kernel are you using? > > I have produced a working fs.py aarch64 example at: > https://github.com/cirosantilli/linux-kernel-module-cheat/tree/singh-mm#gem5-getting-started > (use the singh-mm branch I've created) > > Build and run with: > > ./configure -g && ./build -a aarch64 -g && ./run -a aarch64 -c 4 -g -- > --cpu-type=TimingSimpleCPU > > which uses 4 cores and TimingSimpleCPU. > > After boot finishes, run your benchmark inside the guest with: > > /MM.out > > It completes without errors. > > The setup also worked on arm instead of aarch64, but my arm setup is running > very slowly for some reason which I don't understand yet: > https://github.com/cirosantilli/linux-kernel-module-cheat/tree/02b433e3ee8edb129c1e286a37ed2c8a8170fefe#benchmark-linux-kernel-boot > so just use the aarch64 one if you can. > > You will also likely want to enable compiler optimizations as described at: > https://github.com/cirosantilli/linux-kernel-module-cheat/tree/02b433e3ee8edb129c1e286a37ed2c8a8170fefe#enable-compiler-optimizations > but I haven't tested it with that setup. > >> On running gem5 binary with --version option I get "Gem5.opt 2.0". >> > > Please provide the actual git SHA from git log, --version is not updated > often and therefore too imprecise. > >> I tried running a simple hello world program with se.py and got the >> same error.
