QEMU Aarch64
************
This target produces an image for
the `QEMU "virt" platform <https://www.qemu.org/docs/master/system/arm/virt.html>`_ using a 64 bit CPU type.
ARM targets differ from MIPS in that the kernel format expected
by QEMU is an "Image" (raw binary file) rather than an ELF
file, but this is taken care of by :command:`run.sh`. Check the
documentation for the :ref:`QEMU` (MIPS) target for more information.
