Hello, List!
Could you tell me, what is the current state for EL2\EL3 (Aarch64)?
Whether they are fully supported, or not?
Am I need to use any command line options to enable them for Aarch64
assembler programs simulation?
Thanks in advance!

Sure you can use both. To enable EL2 support:
qemu-system-aarch64 ${QEMU_OPTS} \
-machine gic-version=3 \
-machine virtualization=true
To boot in secure mode you'll need to use -bios and boot a secure
firmware (like OPTEE for example).

You also need -machine secure=true to turn on EL3 in the virt board.
NB that EL2 is currently only supported (1) for AArch64 EL2 and
(2) with GICv3, not for AArch32 EL2 or with GICv2.
thanks
