此报告表明由于零除错误而触发内核严重错误，我们可以进一步知道它是AppleIntelFramebufferController::SetupDPTimings(AppleIntelFramebuffer*, AppleIntelDisplayPath*, AppleIntelFramebufferController::CRTCParams*)在我们反汇编可执行文件后命名的函数内触发的。

对于内置4K显示器的笔记本电脑，我建议使用0x14（HBR2,5.4 Gbps）作为最大链路速率。 对于内置1080p显示器的笔记本电脑，我建议使用0x0A（HBR，2.7 Gbps）。 如果这些值在您的设备上不起作用，您可能需要尝试0x06（RBR，1.62 Gbps）和0x1E（HBR3,8.4 Gbps）。 换句话说，您只需C1 14用C1 06或C1 1E相应地替换最后两个字节。

核显的显示器接口

connector-type的一种定义

  • 00 04 00 00 -->DP
  • 00 08 00 00 -->HDMI
  • 04 00 00 00 -->DVI
  • 02 00 00 00 -->LVDS
  • 01 00 00 00 -->虚拟显示，可能是远程调用的。

SMBIOS

  • iMac18,1 这个机型是使用核显做显示器输出的，从AGPM的info.plist信息中能看到这种机型为iGPU做了很多的设置。
  • iMac18,3/18,2 这个机型独显做显示输出，核显仅参与一些计算任务，这种机型的AGPM的info.plist信息中，iGPU的设置参数做了简化。
  • iMacPro1,1 MacProX,X 独显输出，默认不开启核显，而且独显有各种机型的专用显卡硬件ID匹配，没有iGPU的设置参数。
  • 其他机型类似，你需要到/System/Library/Extensions/AppleGraphicsPowerManagement.kext/Contents/info.plist里去核对。
