Description:
|
The /sys/devices/.../waiting_for_supplier attribute is only
|
present when fw_devlink kernel command line option is enabled
|
and is set to something stricter than "permissive". It is
|
removed once a device probes successfully (because the
|
information is no longer relevant). The number read from it (0
|
or 1) reflects whether the device is waiting for one or more
|
suppliers to be added and then linked to using device links
|
before the device can probe.
|
|
A value of 0 means the device is not waiting for any suppliers
|
to be added before it can probe. A value of 1 means the device
|
is waiting for one or more suppliers to be added before it can
|
probe.
