Hi Sindhuja, Are you using your own python script to configure the simulation? If I'm not mistaken calling the /sbin/m5 checkpoint exits the m5.simulate() (from the script), returning the exit_event (a string "checkpoint"). Then, your python script should capture that exit_event and create th

Hello, It should be X86 (capitol X) instead of x86. You can see the files in gem5/build_opts for the different possibilities for default build variables. Cheers, Jason On Thu, Sep 2, 2021 at 3:58 AM Sravani Sravanam 20PHD7041 via gem5-users < gem5-users@gem5.org> wrote: > sir, > i am sravani s

It seems that thanks to the manuals I was able to advance something, but after a while loading the OS a failure appears that closes the simulation. On the gem5 console you see the following: $~/gem5/build/ARM/gem5.opt ~/gem5/configs/example/fs.py --mem-size 2048MB --disk-image ~/full_system_for

Hi Pedro, Thanks for taking the time to reply. You're right. The implementation was missing in my own python script. After including that, I am able to generate the checkpoint. Thanks & Regards Sindhuja -Original Message- From: Pedro Becker via gem5-users Sent: Thursday, September 2,

Hi, I think while building gem5, I may have missed something. And I didn't realize it during testing the `hello` binary. Now, whenever any binary uses file operations (like `fopen`) then I get the following error: ``` build/X86/sim/syscall_emul.cc:66: fatal: syscall newfstatat (#262) unimplement

Hello Giacomo, Thanks for your reply. I understand what you mean is that if I rename fp operations, it will need to rename the single/double precision operand, and in gem5 we use elements of SIMD vector registers to do this kind of rename. But I still get confused why we use the elements of SIM

The standard library you're linking against is newer, and is using a system call that gem5 doesn't implement. You'll either need to use an older standard library, or implement that system call. If you're trying to run gem5's tests, then I know at least one of the x86 ones uses dynamic linking and l

Hi Sravani, Your VirtualBox needs more memory. You can try to increase its memory to 16GB. Best, Xiongfei From: Sravani Sravanam 20PHD7041 via gem5-users [mailto:gem5-users@gem5.org] Sent: Friday, September 3, 2021 2:03 PM To: ja...@lowepower.com Cc: gem5-users@gem5.org; Sravani Sravanam 20PHD70
