Last Kernel Version that supports Interrupt Interception

[Karim Abdel Hamid]

Hey guys, I'm new to the forums, and new to kernel modding! What is the last Linux Kernel version that supports intercepting software interrupts from the IVT/IDT to the driver? I need to inject my own driver instead. I know this isn't supported anymore and isn't advised, but I still need to implement it that way. Thank you in advance!

An interrupt is a signal that the hardware can send when it wants the processor's attention. Linux handles interrupts in much the same way that it handles signals in user space. For the most part, a driver needs only register and handler for its device's interrupts, and handle them properly when they arrive.
The Last Kernel Version that supports Interrupt Interception in Linux is 4.6.
To check interrupts in the system, type the following Command in the Terminal:
$ watch –n1 “cat/proc/interrupts”
This Command shows interrupts occurring in the system per second.
