这个是怎么回事呢？

vdc开始到random: crng init done 将近花了1min ？

init: Service 'exec 3 (/system/bin/vdc --wait cryptfs enablefilecrypto)' (pid 1753) exited with status 0 waiting took 59.882000 seconds

我最近也遇到了类似启动开机慢的问题，可以跟一下这里的代码，应该是data的文件加密花了59秒导致耗时太长了，源码在android/system/core/init/builtins.cpp 中的 installkey命令，init.rc调用了这个命令去加密data/目录。
不过这个时间可以优化嘛？大佬这么长时间过去了，有没有解决。参考最新的android12代码，我发现android没有做加密/data 目录的动作了（分区表没有配置加密选项）。

@memory 您好我想问一下a133的mipi lcd为什么点不亮
