- .. _MIPS-System-emulator:
- MIPS System emulator
- --------------------
- Four executables cover simulation of 32 and 64-bit MIPS systems in both
- endian options, ``qemu-system-mips``, ``qemu-system-mipsel``
- ``qemu-system-mips64`` and ``qemu-system-mips64el``. Five different
- machine types are emulated:
- - The MIPS Malta prototype board \"malta\"
- - An ACER Pica \"pica61\". This machine needs the 64-bit emulator.
- - MIPS emulator pseudo board \"mipssim\"
- - A MIPS Magnum R4000 machine \"magnum\". This machine needs the
- 64-bit emulator.
- The Malta emulation supports the following devices:
- - Core board with MIPS 24Kf CPU and Galileo system controller
- - PIIX4 PCI/USB/SMbus controller
- - The Multi-I/O chip's serial device
- - PCI network cards (PCnet32 and others)
- - Malta FPGA serial device
- - Cirrus (default) or any other PCI VGA graphics card
- The Boston board emulation supports the following devices:
- - Xilinx FPGA, which includes a PCIe root port and an UART
- - Intel EG20T PCH connects the I/O peripherals, but only the SATA bus
- is emulated
- The ACER Pica emulation supports:
- - MIPS R4000 CPU
- - PC-style IRQ and DMA controllers
- - PC Keyboard
- - IDE controller
- The MIPS Magnum R4000 emulation supports:
- - MIPS R4000 CPU
- - PC-style IRQ controller
- - PC Keyboard
- - SCSI controller
- - G364 framebuffer
- The Fuloong 2E emulation supports:
- - Loongson 2E CPU
- - Bonito64 system controller as North Bridge
- - VT82C686 chipset as South Bridge
- - RTL8139D as a network card chipset
- The Loongson-3 virtual platform emulation supports:
- - Loongson 3A CPU
- - LIOINTC as interrupt controller
- - GPEX and virtio as peripheral devices
- - Both KVM and TCG supported
- The mipssim pseudo board emulation provides an environment similar to
- what the proprietary MIPS emulator uses for running Linux. It supports:
- - A range of MIPS CPUs, default is the 24Kf
- - PC style serial port
- - MIPSnet network emulation

- .. _nanoMIPS-System-emulator:
- nanoMIPS System emulator
- ~~~~~~~~~~~~~~~~~~~~~~~~
- Executable ``qemu-system-mipsel`` also covers simulation of 32-bit
- nanoMIPS system in little endian mode:
- - nanoMIPS I7200 CPU
- Example of ``qemu-system-mipsel`` usage for nanoMIPS is shown below:
- Download ``<disk_image_file>`` from
- https://mipsdistros.mips.com/LinuxDistro/nanomips/buildroot/index.html.
- Download ``<kernel_image_file>`` from
- https://mipsdistros.mips.com/LinuxDistro/nanomips/kernels/v4.15.18-432-gb2eb9a8b07a1-20180627102142/index.html.
- Start system emulation of Malta board with nanoMIPS I7200 CPU::
- qemu-system-mipsel -cpu I7200 -kernel <kernel_image_file> \
- -M malta -serial stdio -m <memory_size> -hda <disk_image_file> \
- -append "mem=256m@0x0 rw console=ttyS0 vga=cirrus vesa=0x111 root=/dev/sda"
