     13     QEMU Aarch64
     14     ************
     15 
     16     This target produces an image for
     17     the `QEMU "virt" platform <https://www.qemu.org/docs/master/system/arm/virt.html>`_ using a 64 bit CPU type.
     18 
     19     ARM targets differ from MIPS in that the kernel format expected
     20     by QEMU is an "Image" (raw binary file) rather than an ELF
     21     file, but this is taken care of by :command:`run.sh`. Check the
     22     documentation for the :ref:`qemu` target for more information.
