validate - 2021.1 English

The validate command 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. Checks PCI Express link status.
3. Runs a verify kernel on the card.
4. Performs the following data bandwidth tests:
   1. DMA test: Data transfers between host and card memory through PCI Express.
   2. DDR or HBM test: Data transfers between kernels and card memory.

It has the following command line format:

xbutil validate [-d card]

The following table lists the available option.

The following is an example of the output after running this command:
