H A D | sysfs-devices-supplier | 287905e6 Thu May 21 14:17:58 CDT 2020 Saravana Kannan <saravanak@google.com> driver core: Expose device link details in sysfs
It's helpful to be able to look at device link details from sysfs. So, expose it in sysfs.
Say device-A is supplier of device-B. These are the additional files this patch would create:
/sys/class/devlink/device-A:device-B/ auto_remove_on consumer/ -> .../device-B/ runtime_pm status supplier/ -> .../device-A/ sync_state_only
/sys/devices/.../device-A/ consumer:device-B/ -> /sys/class/devlink/device-A:device-B/
/sys/devices/.../device-B/ supplier:device-A/ -> /sys/class/devlink/device-A:device-B/
That way: To get a list of all the device link in the system: ls /sys/class/devlink/
To get the consumer names and links of a device: ls -d /sys/devices/.../device-X/consumer:*
To get the supplier names and links of a device: ls -d /sys/devices/.../device-X/supplier:*
