How to shut it down, if it's impossible, find out the evidence.

[Martins3]

• [ ] find out the interrupt source?

[Martins3]

• [ ] we should make a test on the Loongarch
  • [ ] read value in the guest int register
  • [ ] if interrupt happens, how guest got notified? 就算是从 EXCCODE_INT 出来，CPU 还是要进入到 host 的中断处理函数中间，那么，从那条指令开始进入到 host 的中断处理函数中的?

[Martins3]

在进入的虚拟机的时候， local_irq_disable(); 那么为什么还是可以接受到中断。
