      3 MIPS System emulator
      4 --------------------
      5 
      6 Four executables cover simulation of 32 and 64-bit MIPS systems in both
      7 endian options, ``qemu-system-mips``, ``qemu-system-mipsel``
      8 ``qemu-system-mips64`` and ``qemu-system-mips64el``. Five different
      9 machine 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 
     22 The generic emulation is supported by Debian 'Etch' and is able to
     23 install Debian into a virtual disk image. The following devices are
     24 emulated:
     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 
     34 The 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 
     48 The 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 
     55 The 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 
     65 The 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 
     77 The 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 
     87 The 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 
     97 The mipssim pseudo board emulation provides an environment similar to
     98 what 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

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