| 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 |
| ~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| 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 |

| |
| 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" |
