Hello community Experts!
I am doing some experiments with arm64 host machine. The host machine is kunpeng 920 5251k. I try to boot a virtual machine with the following command:
qemu-system-aarch64 -cpu cortex-a53 -enable-kvm -smp 1 -m 4096 -M virt,gic-version=3
Here I have modified the code, and change kvm_target from QEMU_KVM_ARM_TARGET_CORTEX_A53 to 5(generic arm v8).
when the vm boots, I try to use lscpu, but I still saw some feature flags like atomics exist.
So my question is how can I modify aa64isar0 register correctly? Thank you very much for the generous support!
