The CPU pushes the current Flags register, Code Segment, and Instruction Pointer onto the stack. This ensures the CPU "remembers" what it was doing.

Imagine your CPU is reading a book (executing a program). Suddenly, the doorbell rings (a keyboard press or a data packet arrival). The CPU needs to know exactly where to stop, how to handle the guest at the door, and how to get back to its page. ivthandleinterrupt

If you’re writing a driver and need to handle interrupts, you don’t call ivthandleinterrupt directly. Instead, you subclass IOInterruptEventSource . But knowing the underlying function helps when you step through with a kernel debugger (KDK). The CPU pushes the current Flags register, Code

In the realm of computer programming, particularly in the context of operating systems and low-level system programming, the concept of interrupt handling is crucial. Interrupts are signals to the CPU that an event has occurred and requires immediate attention. One of the key data structures involved in interrupt handling is the Interrupt Vector Table (IVT). This article aims to delve into the specifics of ivthandleinterrupt , exploring its role, functionality, and significance in the programming world. Suddenly, the doorbell rings (a keyboard press or
