validate

The validatecommand generates a high-level, easy to read summary of the installed card. It validates correct installation by performing the following set of tests:

1. Validates the card found.
2. ChecksPCI Expresslink status.
3. Runs a verify kernel on the card.
4. Performs the following data bandwidth tests:
   1. DMA test: Data transfers between host and FPGA DDR throughPCI Express.
   2. DDR test: Data transfers between kernels and FPGA DDR.

It has the following option:

• -d (Optional): Specifies the target card ID. Default validates all the cards installed in the system.

For example, to run thevalidatecommand on card ID = 0, enter the following:

$ xbutil validate -d 0

An example of the returned information is shown below:
