: When a hardware device (like a keyboard or timer) sends a signal, or the CPU encounters an error (like division by zero), the CPU pauses its current task and looks up the corresponding vector in the IVT to find the handler. 2. The Role of ivthandleinterrupt
, where the hardware reports a violation through a fault-recording register. 3. Operational Flow ivthandleinterrupt
To understand ivthandleinterrupt , you must first understand the Interrupt Vector Table. : When a hardware device (like a keyboard
Having the Driver Verifier tool active can trigger this BSOD if it detects even minor illegal DMA operations. Troubleshooting Steps Troubleshooting Steps : Save the current state of
: Save the current state of the CPU and registers.
In more complex systems (e.g., external interrupt controllers like the GIC-400), this step involves reading a register like GICC_IAR .
: It executes the necessary logic (e.g., reading a byte from a serial port or incrementing a system clock).
