Today, the Interrupt Vector Table has evolved into the IDT (Interrupt Descriptor Table), and modern CPUs handle context switching with hardware assistance. The messy, manual labor of IvtHandleInterrupt is often hidden behind C++ exceptions and kernel schedulers
In modern computing, peripherals like graphics cards, network adapters, and external Thunderbolt drives use to read and write directly to system RAM without taxing the CPU. To prevent malicious or poorly coded hardware from tampering with system memory, Windows relies on technologies like Intel VT-d or AMD-Vi (collectively categorized under IOMMU). ivthandleinterrupt
Can the handler be interrupted by another interrupt? Today, the Interrupt Vector Table has evolved into
But somewhere in the thousands of lines of assembly, the phone lines were crossed. peripherals like graphics cards
