  • Method to test direct memory access (DMA) address capabilities at high address values
    Patent number: 11386028
    Abstract: 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.

  • Task management
    Patent number: 9965407
    Abstract: In one example, place IO commands on queues which is to cause an application module to initiate IO operations, place task management commands on queues which is to cause the application module to initiate task management operations including sending task marker requests to the target interface module, place task marker on respective queues responsive to task marker requests associated with the task management commands, and receive a task marker completion message indicating receipt of IO commands and task management commands associated with the task marker requests.
