内核 cmdline
必要参数 [1]
pd_ignore_unused clk_ignore_unused efi=novamap
pd_ignore_unused
保持所有已由引导加载程序启用的电源域处于打开状态，即使没有驱动程序声明它们。
clk_ignore_unused
即使没有驱动程序认领启动时钟，也要保持启动时钟开启。
efi=novamap
在ExitBootServices（）之后未调用SetVirtualAddressMap（）
可选参数 [2]
earlycon=efifb,mem video=efifb:off debug panic=10
earlycon=efifb,mem
启用EFI帧缓冲区上的早期内核消息输出。非常有用，建议用于早期内核调试。
video=efifb:off
禁用efifb帧缓冲区。由于未知原因，efifb严重影响了我手机的性能。禁用它可以提高性能。除非您有其他fb，例如simplefb，否则不要禁用
Windows
适配触摸屏[3]
首先，您需要确保您的DSDT表不是很坏，并且qcep等核心驱动程序能够正确加载。
DSDT中的以下部分演示了如何在Oneplus 6t上实现Synaptics触摸。
