| What: /sys/devices/.../waiting_for_supplier |
| Date: May 2020 |
| Contact: Saravana Kannan <saravanak@google.com> |
| 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. |
