You need to be root to connect to the docker Daemon. You can also add yourself to the docker group and reboot if I remember correctly. Gabriel ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %

Hi Sravani, I can't find the '1s' you are talking about. Overall, I would recommend reading a python tutorial as well as a C++ tutorial if you want to feel comfortable enough while reading "Learning gem5". Dependencies are either installed using apt (or any regular package manager) or built wi

Hi Deric, This is a known issue. You can work around the problem in two different ways: 1) Cross-compile your program for aarch64 2) Hardcode the ISA.highestELIs64 to false as you are effectively cross-compiling for AArch32 Kind Regards Giacomo > -Original Message- > From: Deric Cheun

Hi Burak, This is a python configuration problem. You need to make sure the table walker port is connected. Please double check the ArmMMU.walkerPorts() method is called in the FS script Kind Regards Giacomo > -Original Message- > From: Burak Öçalan via gem5-users > Sent: 22 August 20

Hi Pedro, The MSR (immediate) is the software interface for modifying the PSTATE of the PE. In this case the instruction is trying to change the PSTATE.UAO field, which is not implemented in gem5 This is why you are not able to restore the checkpoint in atomic. Implementing UAO should fix it.

Thanks Deric, I wonder if it is linked to this problem: https://gem5.atlassian.net/jira/software/c/projects/GEM5/issues/GEM5-1074 What happens if you cross-compile for aarch64? Kind Regards Giacomo > -Original Message- > From: Deric Cheung via gem5-users > Sent: 16 August 2021 15:25

Hi Giacomo, Thanks! Now that you mentioned UAO I found this: https://gem5.atlassian.net/browse/GEM5-685?focusedCommentId=11858 (comment in a gem5 Jira issue), reporting that disabling UAO when building the kernel worked. So I'm going to try that and I'll report the steps here if it goes well!

Hi, I already answered a similar question from you. You need to be root or to be part of the docker Unix group as detailed here: https://www.journaldunet.fr/web-tech/developpement/1497415-comment-corriger-l-erreur-docker-got-permission-denied/. Again, I would strongly advise that you get famili

Hi, all. I am trying to run some experiments about sparse matrix multiplication, and it is mainly about float multiplication and addition. To ensure the compiler doesn't vectorize the source code, I compile this source code with GCC flag " -march=armv8-a+nosimd+nosve " .this should indicate that
