The hero of our story is the . On Intel systems, this technology is called VT-d (Virtualization Technology for Directed I/O). On AMD systems, it is called AMD-Vi (AMD Virtualization Technology for I/O).
VT-d allows for granular control. It can remap devices based on their PCIe BDF (Bus, Device, Function). It also supports , which is crucial for security. Without interrupt remapping, a malicious device could generate fake interrupts to trick the CPU into executing malicious code. pcie device remapping
In consumer hardware, "PCIe Remapping" is often a BIOS toggle that alters how the motherboard's chipset views M.2 and PCIe slots. The hero of our story is the
