- interrupt
|
||
- 是gicv3函数的调用
|
||
- gicv3
|
||
- 封装gicv3相关代码 **可以通过这里学习gicv3**
|
||
- psci
|
||
- 就是psci的电源管理的东西 找个专题专门看
|
||
- smccc
|
||
- 封装svc hvc
|
||
- stack
|
||
- 没看懂，没啥用
|
||
- mmu
|
||
- gtimer
|
||
- gtimer相关使用，主要是调用cpu_gcc.s中对gtimer的封装函数
|
||
- trap
|
||
- entry_point(gcc)
|
||
- \_start 入口函数 启动 rtthread_startup
|
||
- 看着没什么用的
|
||
- startup(gcc)
|
||
- vector(gcc)
|
||
- - <span style="color:#a4a4a2">gic</span>
