Yes, aarch64 kvm has been tested with qemu-system-aarch64. Initial patches
for QEMU aarch64 were aimed at supporting only KVM but recently quite
a few patches have been posted for TCG aarch64 emulation.

Largely, the approach in QEMU is to have qemu-system-aarch64 share most
of the code with qemu-system-arm. In fact, for qemu-system-aarch64 TCG
emulation and aarch64 kvm code is located in target-arm directory which is
originally meant for qemu-system-arm.
