My IFB is not working after recent update in the kernel on my Orange Pi Zero 3

从当前运行内核的配置文件中查找

           zcat /proc/config.gz | grep CONFIG_IFB
           # 如果上面的命令不行,就试试这个备用的:
           grep CONFIG_IFB /boot/config-$(uname -r)

CONFIG_IFB is not set

CONFIG_IFB is not set

I tried to compile it from source code to add it back, but failed. Anyone can help? I need this for my cake-autogate.
