[gem5-users] DMA Assert help
Hey everyone. I've been trying to implement a custom simobject but once DMA starts it quickly fails as for an assert. I don't know why it could happen and would appreciate some ideas.

[gem5-users] SimpleMemobj in FS simulation?
Hello everyone. Recently I've been trying to create a new memory object to run in FS simulation. For it i use the SimpleMemobj (https://www.gem5.org/documentation/learning_gem5/part2/memoryobject/) code as a template. During FS tests, I've run into a lot of troubles causing the simulation to stall or an assert to fail. Trying out the same object in SE mode seemed to work properly. Is there any big change i missed? Should I use a different object as a template? If so, which one? -- Thank you for the help, Miguel Antonio Avargues Gutiérrez. ___ 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

I don't know whether parsec.img would work with configs/fs.py; however, we've been testing and using parsec.img with the gem5 configs from gem5-resources (https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/parsec/configs/) [1]. You can modify the configs from [1] to run command line commands (which, I guess, would have the same behaviors as --script from configs/fs.py). Specifically, in the writeBenchScript() function in run_parsec.py, the content inputted to bench_file.write() will eventually be appended to .bashrc during gem5 simulation. Since you mentioned newer Linux kernel versions, it is known that the current state of the configs from [1] would run into a kernel panic when running the simulation with newer Linux kernel versions.

[gem5-users] Re: Gem5 in FS mode
Hi Vaidya. Sorry for the delay. In order to mount your file to your linux system you should first seek the start of the file system, you can do this with the order "parted". Once the program asks you for orders you should change the units to bytes "unit B" and then "print" the image info. If this is too complicated, you can try to use either 32256 or 104856 as the offset. Being the latter the most usual. From that you should get that start byte of the image, which you'll need to mount using the order: "sudo mount -o loop,rw,offset= <.img_file_to_mount> /mnt" Once this is done, you can copy your files to the /mnt dir or any subdirectories of /mnt. Be wary not to change any crucial system files. After you have finished adding the files needed, you must unomunt the image file. You can do this by running "umount /mnt" in any other directory that is not /mnt or any subdirectories. Un saludo, Miguel Antonio Avargues Gutiérrez.

[gem5-users] Re: Disk image for FS
Hi Vaidya. You have to mount the disk image that you are using for FS simulation with the compiled binaries that you want to add. After that, you can run your simulation and run the binaries either in interactive mode or with the --script argument when you launch the simulation (the same way you point to a disk image or a kernel). I recommend that you download both the kernel and the disk image from this https://www.gem5.org/documentation/general_docs/gem5_resources/ <https://www.gem5.org/documentation/general_docs/gem5_resources/> link. Get the "parsec" disk image and the corresponding kernel for it. Un saludo, Miguel Antonio Avargues Gutiérrez.

[gem5-users] Re: Disk image for FS
Thanks for the help Hoa. I have downloaded the parsec.img disk image and the right kernel version from [1]. It seems to boot properly when using the fs.py config script but i don't get a terminal to interact with the simulated system using telnet. Is that expected because i need to use the --script parameter or am I missing something? Greetings, Miguel antonio Avargues Gutiérrez.

[gem5-users] Disk image for FS
Hello everyone. I'm a pretty new user to gem5 and I've been trying to get a FS simulation going on with a newer kernel version and a custom disk image. Unfortunately i feel like my disk image isn't properly created since i can't get the simulation going. Is there any up-to-date tutorias about making a custom file image? All the tutorias i've found make references to files that i can't find in the simulator (such as util/m5/Makefile.x86). I am using version 20.0.0.3 and I can't change it. -- Greetings, Miguel Antonio Avargues Gutiérrez. ___ 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
