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.
