Hello,

On Linux when interrupts are defined similar to below, what defines say
ide2, ide3 to be on the same interrupt? The bios, linux, the driver using the interrupt? And can that be controlled/overrode at the kernel/driver level?


Typically this is determined by the hardware routing of the interrupt lines on the motherboard, occasionally the BIOS. There isn't usually much that can be done about the sharing at the kernel level.
