Hello all,
I am trying to do some experiments in which I need to insert some codes before an interrrupt is dispatched. But I don't know where I should insert the codes.
Basically, when an interrupt arrives, the kernel needs to call the corresponding interrrupt handler. I need to insert some codes before any interrupt is dispatched.
Could anyone tell me which file in the kernel (4.8) I should look at for interrupt distpatching?
Thanks Haidong
