Ivthandleinterrupt [exclusive]
ivthandleinterrupt is the dispatcher. It is the code responsible for saving the current state of the processor, executing the necessary logic for the specific event, and then restoring the processor so it can go back to its original task without a hitch. How the Process Works
// Example IVT structure typedef struct void (*handlers[16])(void); // Array of interrupt handler pointers IVT;
Many real-time operating systems (RTOS) like VxWorks also rely heavily on the IVT concept, providing developers with APIs to directly connect hardware interrupts to their custom service routines for low-latency performance. This foundational mechanism is critical for all modern OSes. ivthandleinterrupt
: Updating this can fix IOMMU flagging issues that lead to DMA violations.
Windows leverages the IOMMU through a feature called . ivthandleinterrupt is the dispatcher
