[gem5-users] Re: Porting a configuration file from gem5 v20 to gem5 v21
Hi Jason, I am not sure this is the same issue. I compiled the hello.c example using the below make file and run it in se mode using my config file and still received the segmentation error: CC=aarch64-linux-gnu-gcc CFLAGS=-Wall -g3 -march=armv8-a -static -O0 # -I../ all: arm arm: $(CC) $(CFLAGS) -c hello.c -o hello.o $(CC) $(CFLAGS) hello.o -o hello Please advise.

[gem5-users] Re: Wrong stats in gem5 v21.1
I'm pretty sure the issues you are experiencing were fixed in the latest hotfix release: v21.1.0.2. You can get this by pulling the latest version from the gem5 repo's stable branch: https://gem5.googlesource.com/public/gem5/ Kind regards, Bobby -- Dr. Bobby R.

Hi Ali, Is your guest code 32-bit Arm? If so, I think this could be the problem in SE mode: https://gem5.atlassian.net/browse/GEM5-1074 Cheers, Jason On Tue, Oct 5, 2021 at 7:45 AM Ali Ghandour via gem5-users < gem5-users@gem5.org> wrote: > In FS mode, full errror stack below: > > Traceback (most recent call last): > File "", line 1, in > File "build/ARM/python/m5/main.py", line 455, in main > File "./RPIv4.py", line 535, in > main() > File "./RPIv4.py", line 512, in main > root.system = systemCreate(args) > File "./RPIv4.py", line 297, in systemCreate > system = RPISystemCreate(ArmSystem, args, mode) > File "./RPIv4.py", line 182, in RPISystemCreate > return RPISystem(args, mode) > File "./RPIv4.py", line 127, in __init__ > self.configMem(args) > File "./RPIv4.py", line 158, in configMem > self.cpu_cluster.connectDirect(self.membus) > File > "/home/ali/Desktop/spirals/reproduce-spectre-gem5/gem5/./ARMv8A_Cortex_A72.py", > line 325, in connectDirect > cpu.dtb.walker.port = bus.slave > File "build/ARM/python/m5/SimObject.py", line 1416, in __getattr__ > AttributeError: object 'ARM_A72_TLB_L1D' has no attribute 'walker' > (C++ object is not yet constructed, so wrapped C++ methods are > unavailable.) > ___ > gem5-users mailing list -- gem5-users@gem5.org > To unsubscribe send an email to gem5-users-le...@gem5.org > %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s > ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
[gem5-users] Re: How can I Run Full system on Ubuntu18.04 and X86?
Hello Jeongmin. I recommend you use a pre-compiled Kernel and disk image from the gem5 resources web page (https://www.gem5.org/documentation/general_docs/gem5_resources/), as they are kinda tested. Hope it helps! Un saludo, Miguel Antonio Avargues Gutiérrez. El 06/10/2021 a las 4:46, Jeongmin via gem5-users escribió: Hi All, I'm trying to use the Gem5 full system. but It doesn't work. These are my configurations -kernel = vmlinux-4.19.83 (5.4.49 / 4.14.134) -Ubuntu = ubuntu-18.04.6-live-server-amd64 (tried 16.04) -gem5 = 21.1.0.2 -X86 architecture -I will use an O3CPU and DRAMsim3. I made an image by using qemu and I completed the booting system. To make the image, I use this command "qemu-system -hda -cdrom -m 8G -enable-kvm" The image size for ubuntu18.04.6 is 8.6GB. All files are in ~/gem5/fs and I changed "M5_PATH" to "/home/user/gem5/fs" in Syspath.py line 34. As far as I know, These are all configurations to use the gem5 full system. So I ran gem5. but it does not work. I attached all command and error messages below. How can I run the gem5 full system? Please let me know.
