Trap vs Interrupt in Operating System - javatpoint

WebUnder this scheme, the VMM should immediately forward all hardware interrupts back to the host operating system. The trap frame will allow the VMM to quickly save the guest operating system’s basic state, and then the other CPU state should be saved as well. Then the VMM should place the trap on the host operating system’s TSS and jump the ... WebThe interrupt handler must run quickly, because it's preventing any other interrupt from running. In the Linux kernel, interrupt processing is divided in two parts: The “top half” is the interrupt handler. It does the minimum necessary, typically communicate with the hardware and set a flag somewhere in kernel memory. WebAn interrupt is a signal emitted by a device attached to a computer or from a program within the computer. It requires the operating system (OS) to stop and figure out what to do next.
