推荐答案
例子可以在Linux源代码树中找到的 OMAP2 的平台。
Examples can be found in the Linux source tree for the OMAP2 platform.
- omap-smc.S
- omap-secure.h
- omap-secure.c

基本上，什么都对接人梦想了一个 SWI 或 SVC 接口可以通过<$使用C $ C> SMC 接口。否则，这个问题是无法具体回答。
Basically, what ever interface people dream up for an SWI or SVC interface can be used by the SMC interface. Otherwise, this question is impossible to answer specifically.
