User Diagnostics for Windows NIC Driver Management Applications: QLogic QME8242 Mezzanine Card User's Guide This section provides descriptions of the following Windows diagnostic tests: Hardware Test Register Test Interrupt Test Loopback Test Link Test Hardware Test The hardware test checks the status of various hardware blocks, including DMA Engines, Receive Engine, and on-board processor meta cores. Register Test The register test performs device register read/write accesses. Interrupt Test The interrupt test checks the ability of the hardware to create an interrupt and the ability of the driver to process the interrupt by forcing the generation of a predetermined number of interrupts. The test succeeds if the device generates the interrupts and the driver processes all interrupts expected. Loopback Test The loopback test is a diagnostic tool that routes transmit data through a loopback connector back to the same adapter. Link Test The link test inspects the link status (up or down) by checking the physical communication channel between the host and the firmware. Windows Diagnostic Test Messages If a test fails, an appropriate error code is generated and displayed, as shown in Table 7. Note that this table does not list error messages for the Interrupt and Link tests. Table 7.
