开始编译jailhouse驱动和内核了。
apt install checkinstall build-essential qemu python3-mako export ARCH=arm64 export PATH=$PATH:/root/sdk/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin export CROSS_COMPILE=aarch64-none-linux-gnu-
平台为RK3588，内核版本如下:
VERSION = 5 PATCHLEVEL = 10 SUBLEVEL = 160
补丁如下
