1、TEE API介绍
TEE API分两种:
- 一类是CA与TA通信的API，实现方式就是应用程序调用libteec.so库，libteec.so库是由optee_client编译出的，libteec.so中调用了dev/tee_priv节点陷入kernel
mode，在kernel mode中调用smc同步异常指令陷入到ATF，ATF再跳出到TEE OS, TEE
OS再将消息发送给相应的TA。
该API在globalplatform中的TEE_Client_API_Specification-V1.0_c.pdf文档中有所规定，api的具体实现是在optee_client/libteec - 一类是TA系统调用TEE OS的API，这是的实现方式其实就是系统调用，调用SVC同步异常指令，进入kernel mode。
该API在globalplatform中的GPD_TEE_Internal_Core_API_Specification_v1.1.pdf文档中有所规定，api的具体实现是在optee_os\lib\libutee
