A method for detecting a Direct Memory Access (DMA) memory address violation when testing PCIe devices is disclosed. The method for detecting a DMA memory address violation when testing PCIe devices applies to unintentional and intentional accesses of memory space outside of an area in memory specified by the device driver developed for the device.

Detection of a DMA (direct memory access) memory address violation when testing PCIE devices

A method for detecting a Direct Memory Access (DMA) address capability at high address values when testing PCIe devices is disclosed. The method includes enabling an input/output (I/O) memory management unit (IOMMU); remapping physical addresses to virtual addresses at a high end of an address range; adding a peripheral component interconnect express (PCIe) device; and mapping physical memory addresses to high value memory addresses.
