Build ARM image for Gem5 FS simulation #16

Open Dauto98 opened 3 years ago

Dauto98 commented 3 years ago

Dear cirosantilli2,

I am building a disk image for Gem5 ARM full system simulation. My goal is to build an image similar to the x86 image, where I can ./m5term localhost 3456 and do whatever I want inside the virtual machine.

However, packer always yields errors. My json file is the same as this, except the qemu is qemu-system-aarch64 and ubuntu server arm64. It and other related files are taken from this tutorial. I also tried packer-builder-arm but it yielded another error related to qemu.

I turned to using qemu directly, but this command line

qemu-system-aarch64 
    -drive file=boot-exit-image/boot-exit.img,format=raw 
    -cdrom packer_cache/d60fab3d2cbda6b0379a55b2ab92292fe6342d41.iso 
    -m 1024 
    -machine virt 
    -cpu cortex-a15 
    -boot d

only a qemu monitor window popup and nothing else happen. I don't know what to do next.

What is the right way to run and build aarch64 image for Gem5?

Hi Duc,

I'm not familiar with the Packer setup. It should work in theory, but would need debugging.

What I have been using instead is Buildroot as shown at: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/6efe2fb4e1a9f9f06032560d57011829797c8478#gem5-buildroot-setup-getting-started

Buildroot also builds an image like Packer, but it does everything with cross compilation, without the need for QEMU, which is much neater.

That one I can guarantee it works on Ubuntu host, I've used it countless times, and if you find a problem, I'll likely be able to help out, do open an issue in the repo if it fails.
