Hi,
It appears on juno, I can start kvm with UEFI only on cortex-a53 cores:
taskset -c 0 qemu-system-aarch64 -m 1024 -cpu host -M virt -bios QEMU_EFI.fd -enable-kvm -nographic -> works: UEFI Interactive Shell v2.0 taskset -c 1 qemu-system-aarch64 -m 1024 -cpu host -M virt -bios QEMU_EFI.fd -enable-kvm -nographic -> hangs at cpu spinning 100% ...
Qemu and kernel are latest mainline, kvm from last months Ĺinaro release. According to cpuinfo cores 0 and 3-5 are a53 and 1-2 are a57. Details:

I can reproduce the hang, both with your UEFI binary and my own release build. The debug build works fine, unfortunately...

OK, it appears that we were missing some cache maintenance. It is not obvious how that should affect A57 only, but with these patches, I can now reliably run the release version on my Seattle A57

Let me check with Leif. We have another candidate patch now that he could perhaps apply and kick off a build?

I now have independent confirmation (from Laszlo Ersek) that the cache maintenance patches I am proposing fix the issue on Seattle. Hopefully this means Juno is fixed as well.
I am trying to get a snapshot out asap, today or tomorrow perhaps?
