Sorry to bother you, I would like to ask a question.I want to use qemu to monitor the information of the target thread reading and writing memory. I see that qemu supports the tcg plugin, but I just find the following code in plugin-gen.c .Do I just need to add a record function in it? How do I read the current register values such as rip, rsp, how do I know the current target address and data that the CPU read or written?Is there any reference example?
| /* |

| * direct to the plugin if they are subscribed to. |
| */ |
| void HELPER(plugin_vcpu_udata_cb)(uint32_t cpu_index, void *udata) |
| { } |
|
|
| void HELPER(plugin_vcpu_mem_cb)(unsigned int vcpu_index, |
| qemu_plugin_meminfo_t info, uint64_t vaddr, |
| void *userdata) |
| { } |
