QEMU默认支持的所有开发板、芯片列表

所属的Gitee源码和工程地址：才鲸嵌入式 / 开源安防摄像机（嵌入式软件）

一、QEMU相关文档

• QEMU官方文档
  《Welcome to QEMU’s documentation!》

• QEMU支持的开发板详细信息在源码的docs/system下各个文档中

• 安装git，并 clone qemu代码，代码地址：
  《Gitee 极速下载 / qemu》

• QEMU源码中不包含任何开发板的可执行文件，需要针对不同的开发板用不同的编译工具生成可执行文件后再进行测试

• QEMU有个缺点就是没有实现任何芯片的2D显示加速、视频编解码（芯片中显卡模块的功能），可能是CPU仿这类并行计算的硬件意义不大，应该会非常慢，反而还没有直接写显存来的快，唯一的例外就是树莓派，树莓派支持上述功能。

二、QEMU支持的开发板列表

QEMU默认支持以下架构的CPU：

   target-arm
   target-avr
   target-m68k

Differences between QEMU and real hardware:

• AN385/AN386 remapping of low 16K of memory to either ZBT SSRAM1 or to
  block RAM is unimplemented (QEMU always maps this to ZBT SSRAM1, as
  if zbt_boot_ctrl is always zero)
• AN524 remapping of low memory to either BRAM or to QSPI flash is
  unimplemented (QEMU always maps this to BRAM, ignoring the
  SCC CFG_REG0 memory-remap bit)
• QEMU provides a LAN9118 ethernet rather than LAN9220; the only guest
  visible difference is that the LAN9118 doesn’t support checksum
  offloading
• QEMU does not model the QSPI flash in MPS3 boards as real QSPI
  flash, but only as simple ROM, so attempting to rewrite the flash
  from the guest will fail
• QEMU does not model the USB controller in MPS3 boards
