Hi,

In your experiment, everything runs in the normal world. Hafnium at NS EL2. The primary VM hosting linux at NS EL1.

Regards, Olivier.

Hi,

I have just started to learn about Hafnium and I am following Getting Started steps of it.

I built DTB with

/dts-v1/;

/ { hypervisor { compatible = "hafnium,hafnium"; vm1 { debug_name = "Linux VM"; kernel_filename = "vmlinuz"; ramdisk_filename = "initrd.img"; }; }; };

And after setting up RAM disk, I was able to boot into Linux VM with following command:

qemu-system-aarch64 -M virt,gic_version=3 -cpu cortex-a57 -nographic -machine virtualization=true -kernel out/reference/qemu_aarch64_clang/hafnium.bin -initrd initrd.img -append "rdinit=/sbin/init"

But I am unable to understand whether Hafnium and Linux are running in Normal World or Secure World or At which Level (EL1, EL2, S-EL1 or S-EL2...) Hafnium and Linux are running.

Can I please get some help in understanding this?
