6 accel-config-list - display the platform accfg device(s) topology and
7 attributes in json format

10 accel-config list [<options>]
11 List all the active DSA devices discovered by the driver and the driver
13 exported attributes.
14 Options can be specified to limit the output to devices of a certain
16 grouping where the grouping are devices, groups, work queues and
17 engines. By default, accel-config list with no options is equivalent
18 to:
19 accel-config list --devices --engines --groups --workqueues
