ACCEL-CONFIG LIST(1) accfg Manual ACCEL-CONFIG LIST(1)

NAME

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

SYNOPSIS

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
