Where is the hand interrupt handler for linux?

I go through the source , but I cannot find where the low level asm code is interrupt_vector

and fast_interrupt_vector

or where is the higher level C code called low level vectors. Where is the interrupt code for the hand at?

Interrupt handlers are found in the device driver code. Each type of device has its own driver somewhere in a subdirectory driver

. The driver initialization code usually requests irq from the kernel, passing a function pointer to the handler as a parameter. This means that the service routines are not bundled together, but are essentially "all over the place."
