Linux Devlink Documentation
===========================
devlink is an API to expose device information and resources not directly
related to any device class, such as chip-wide/switch-ASIC-wide configuration.
Locking
-------
Driver facing APIs are currently transitioning to allow more explicit
locking. Drivers can use the existing ``devlink_*`` set of APIs, or
new APIs prefixed by ``devl_*``. The older APIs handle all the locking
in devlink core, but don't allow registration of most sub-objects once
the main devlink object is itself registered. The newer ``devl_*`` APIs assume
the devlink instance lock is already held. Drivers can take the instance
lock by calling ``devl_lock()``. It is also held all callbacks of devlink
netlink commands.
Drivers are encouraged to use the devlink instance lock for their own needs.
Interface documentation
-----------------------
The following pages describe various interfaces available through devlink in
general.

Driver-specific documentation
-----------------------------
Each driver that implements ``devlink`` is expected to document what
parameters, info versions, and other features it supports.
