rec { system = { crossSystem = { config = "mips-unknown-linux-musl"; gcc = { abi = "32"; arch = "mips32"; # maybe mips_24kc- }; }; }; description = '' 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.
