@ -6,7 +6,7 @@ Start to dive into interrupt and exceptions handling in the Linux kernel
We saw some theory about interrupts and exception handling in the [introduction](https://0xax.gitbooks.io/linux-insides/content/Interrupts/linux-interrupts-1.html) and as I mentioned in that part, we will now start to dive into interrupts and exceptions within the Linux kernel source code. We'll commence by initializing the basic components as we did in the other chapters. But, we will not see the Linux kernel source code from the very early [code lines](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/header.S#L292), as this was presented in the example within the [Linux kernel booting process](https://0xax.gitbooks.io/linux-insides/content/Booting/index.html) chapter. In the beginning we will deal with the first sections of the Linux kernel source code, which are related to interrupts and exceptions.

If you've read the previous parts, you can remember that the earliest place in the Linux kernel `x86_64` architecture-specific source code which is related to the interrupt is located in the [arch/x86/boot/pm.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/pm.c) source code file and represents the first setup of the [Interrupt Descriptor Table](http://en.wikipedia.org/wiki/Interrupt_descriptor_table). It occurs right before the transition into the [protected mode](http://en.wikipedia.org/wiki/Protected_mode) in the `go_to_protected_mode` function by the call of the `setup_idt`: If you've read the previous parts, you can remember that the earliest place in the Linux kernel `x86_64` architecture-specific source code, which is related to the interrupt is located in the [arch/x86/boot/pm.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/pm.c) source code file and represents the first setup of the [Interrupt Descriptor Table](http://en.wikipedia.org/wiki/Interrupt_descriptor_table).
