Windows Diagnostic Test Descriptions
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.
