Hi,
I dont know if this is the right place to ask this question.
I am confused by this explaination of fast and slow handlers.

"A fast handler runs with interrupt reporting disabled in the microprocessor, and the \
interrupt being serviced is disabled in the interrupt controller. The handler can \
nonetheless enable reporting in the processor by calling sti.

A slow handler runs with interrupt reporting enabled in the processor, and the \
interrupt being serviced is disabled in the interrupt controller."

Is the interrupt controller some special device for handling all interrupts? why is \
the interrupt being serviced being disabled in it?

Thanks,
Anshuman
