accel-config-list - Man Page

accel-config list [<options>]

List all the active DSA devices discovered by the driver and the driver exported attributes.

Options can be specified to limit the output to devices of a certain grouping where the grouping are devices, groups, work queues and engines. By default, accel-config list with no options is equivalent to:

accel-config list --devices --engines --groups --workqueues
