Dear gem5 community,
I have used the latest gem5 version with the following command:
./build/RISCV/gem5.fast
./configs/example/gem5_library/riscvmatched-fs.py and I boot Ubuntu
successfully. The problem is that after 10 hours of simulation I get
the following error:
Dear Choi,
I have the same results with you except from Runtime Dynamic. As
Andreas said, you may need to check the stats.txt file and the
GEM5toMcPAT.py python script.

Dear gem5 users,
In the past, I got power/energy estimations of ARM and X86 ISAs

I have successfully simulated the HPCG benchmark using ARM Ubuntu in

Dear gem5 community,
I am using configs/example/arm/starter_fs.py configuration in order to
simulate ARM FS. However, I would like to use different clock
frequencies in the CPU and different in the system clock. Is there
this option in the latest gem5 release?
Thank you!
Best regards,
all,
I also ran into the same problem using another benchmark. I want to note
that this problem also appears when using the AtomicCPU.

Is there any update about the accuracy of RISC-V FS?
Best regards,

Jason and I had a theory that this may be due to the "Rounding Mode" for
floating pointing being set incorrectly in FS mode. That's set via a macro

Dear Waliullah,
I think that the image has a gem5_init script that executes the m5
exit command. You can use the image from gem5 resources
(http://dist.gem5.org/dist/v21-2/images/x86/ubuntu-18-04/x86-ubuntu.img.gz)
with vmlinux-5.4.49 kernel

We can turn off the motd service, which would improve the booting time by a
