      1.. _MIPS-System-emulator:
      2
      3MIPS System emulator
      4--------------------
      5
      6Four executables cover simulation of 32 and 64-bit MIPS systems in both
      7endian options, ``qemu-system-mips``, ``qemu-system-mipsel``
      8``qemu-system-mips64`` and ``qemu-system-mips64el``. Five different
      9machine types are emulated:
     10
     11-  A generic ISA PC-like machine \"mips\"
     12
     13-  The MIPS Malta prototype board \"malta\"
     14
     15-  An ACER Pica \"pica61\". This machine needs the 64-bit emulator.
     16
     17-  MIPS emulator pseudo board \"mipssim\"
     18
     19-  A MIPS Magnum R4000 machine \"magnum\". This machine needs the
     20   64-bit emulator.
     21
     22The generic emulation is supported by Debian 'Etch' and is able to
     23install Debian into a virtual disk image. The following devices are
     24emulated:
     25
     26-  A range of MIPS CPUs, default is the 24Kf
     27
     28-  PC style serial port
     29
     30-  PC style IDE disk
     31
     32-  NE2000 network card
     33
     34The Malta emulation supports the following devices:
     35
     36-  Core board with MIPS 24Kf CPU and Galileo system controller
     37
     38-  PIIX4 PCI/USB/SMbus controller
     39
     40-  The Multi-I/O chip's serial device
     41
     42-  PCI network cards (PCnet32 and others)
     43
     44-  Malta FPGA serial device
     45
     46-  Cirrus (default) or any other PCI VGA graphics card
     47
     48The Boston board emulation supports the following devices:
     49
     50-  Xilinx FPGA, which includes a PCIe root port and an UART
     51
     52-  Intel EG20T PCH connects the I/O peripherals, but only the SATA bus
     53   is emulated
     54
     55The ACER Pica emulation supports:
     56
     57-  MIPS R4000 CPU
     58
     59-  PC-style IRQ and DMA controllers
     60
     61-  PC Keyboard
     62
     63-  IDE controller
     64
     65The MIPS Magnum R4000 emulation supports:
     66
     67-  MIPS R4000 CPU
     68
     69-  PC-style IRQ controller
     70
     71-  PC Keyboard
     72
     73-  SCSI controller
     74
     75-  G364 framebuffer
     76
     77The Fuloong 2E emulation supports:
     78
     79-  Loongson 2E CPU
     80
     81-  Bonito64 system controller as North Bridge
     82
     83-  VT82C686 chipset as South Bridge
     84
     85-  RTL8139D as a network card chipset
     86
     87The Loongson-3 virtual platform emulation supports:
     88
     89-  Loongson 3A CPU
     90
     91-  LIOINTC as interrupt controller
     92
     93-  GPEX and virtio as peripheral devices
     94
     95-  Both KVM and TCG supported
     96
     97The mipssim pseudo board emulation provides an environment similar to
     98what the proprietary MIPS emulator uses for running Linux. It supports:
     99
    100-  A range of MIPS CPUs, default is the 24Kf
    101
    102-  PC style serial port
    103
    104-  MIPSnet network emulation

    111~~~~~~~~~~~~~~~~~~~~~~~~
    112
    113Executable ``qemu-system-mipsel`` also covers simulation of 32-bit
    114nanoMIPS system in little endian mode:
    115
    116-  nanoMIPS I7200 CPU
    117
    118Example of ``qemu-system-mipsel`` usage for nanoMIPS is shown below:
