Expand description
The entry of trap handler, which will handle the context switch and distribute the trap to the corresponding function.
The trapframe is defined in axhal module, and the trap handler is defined in axtrap module.
The reason for the separation of definition and implementation is to ensure a one-way dependence on the calling relationship.
The trap handler need to dispatch the trap to the corresponding functions, which use trapframe struct to finish their functions.
If you want to use this module, please ensure that the trap context layout you pass to the handler is in consistent or compatible with the trap frame layout defined in axhal.
Otherwise, you may need to modify the unsafe assembly code of this module to complete the privilege switching function
Functions
