3 MIPS System emulator
4 --------------------
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
11 -  The MIPS Malta prototype board \"malta\"
13 -  An ACER Pica \"pica61\". This machine needs the 64-bit emulator.
15 -  MIPS emulator pseudo board \"mipssim\"
17 -  A MIPS Magnum R4000 machine \"magnum\". This machine needs the
18    64-bit emulator.
22 -  Core board with MIPS 24Kf CPU and Galileo system controller
24 -  PIIX4 PCI/USB/SMbus controller
26 -  The Multi-I/O chip's serial device
28 -  PCI network cards (PCnet32 and others)
30 -  Malta FPGA serial device
32 -  Cirrus (default) or any other PCI VGA graphics card
36 -  Xilinx FPGA, which includes a PCIe root port and an UART
38 -  Intel EG20T PCH connects the I/O peripherals, but only the SATA bus
43 -  MIPS R4000 CPU
45 -  PC-style IRQ and DMA controllers
47 -  PC Keyboard
49 -  IDE controller
51 The MIPS Magnum R4000 emulation supports:
53 -  MIPS R4000 CPU
55 -  PC-style IRQ controller
57 -  PC Keyboard
59 -  SCSI controller
61 -  G364 framebuffer
65 -  Loongson 2E CPU
67 -  Bonito64 system controller as North Bridge
69 -  VT82C686 chipset as South Bridge
71 -  RTL8139D as a network card chipset
73 The Loongson-3 virtual platform emulation supports:
75 -  Loongson 3A CPU
77 -  LIOINTC as interrupt controller
79 -  GPEX and virtio as peripheral devices
81 -  Both KVM and TCG supported
84 what the proprietary MIPS emulator uses for running Linux. It supports:
86 -  A range of MIPS CPUs, default is the 24Kf
88 -  PC style serial port
90 -  MIPSnet network emulation

94 .. _nanoMIPS-System-emulator:
99 Executable ``qemu-system-mipsel`` also covers simulation of 32-bit
102 -  nanoMIPS I7200 CPU
104 Example of ``qemu-system-mipsel`` usage for nanoMIPS is shown below:
