我正在尝试将android O移植到我的设备上，但是由于未创建供应商分区（对于Android O是必需的）而遇到问题，结果是未获取SELinux策略并且引导过程终止了。如何创建供应商分区以将供应商映像刷新到其中。 我的设备在Qualcomm msm8953 SOC上运行。
下面是启动日志。

我自己遇到了这个问题，我认为这与SoC的dts中不完整的defconfig和dm-verity有关。除非您现在已经解决了。
尤其是对于不完整的defconfig，我必须添加诸如CONFIG_PINCTRL_MSM8937=y之类的选项，因为我的android设备在技术上是8937。此外，在arch/arm/boot/dts/qcom/msm8937.dtsi中，我需要从{中拉出verify标志{1}}。
我现在还有其他问题，但是我已经接近启动了。
