1 | .. _MIPS-System-emulator: |
| 2 | ||
| 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 | ||
| c3a09ff6 | 77 | The Fuloong 2E emulation supports: |
| 324b2298 PB |
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 | ||
| c7784e42 HC |
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 | ||
| 324b2298 PB |
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 | |

| 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: | |
