QEMU MIPS
|
|
*********
|
|
|
|
This target produces an image for
|
|
QEMU, the "generic and open source machine emulator and
|
|
virtualizer".
|
|
|
|
MIPS QEMU emulates a "Malta" board, which was an ATX form factor
|
|
evaluation board made by MIPS Technologies, but mostly in Liminix
|
|
we use paravirtualized devices (Virtio) instead of emulating
|
|
hardware.
|
|
|
|
Building an image for QEMU results in a :file:`result/` directory
|
|
containing ``run.sh`` ``vmlinux``, and ``rootfs`` files. To invoke
|
|
the emulator, run ``run.sh``.
|
|
|
|
The configuration includes two emulated "hardware" ethernet
|
|
devices and the kernel :code:`mac80211_hwsim` module to
|
|
provide an emulated wlan device. To read more about how
|
|
to connect to this network, refer to :ref:`qemu-networking`
|
|
in the Development manual.
