1Linux Devlink Documentation
2===========================
3
4devlink is an API to expose device information and resources not directly
5related to any device class, such as chip-wide/switch-ASIC-wide configuration.

7Locking
8-------
9
10Driver facing APIs are currently transitioning to allow more explicit
11locking. Drivers can use the existing ``devlink_*`` set of APIs, or
12new APIs prefixed by ``devl_*``. The older APIs handle all the locking
13in devlink core, but don't allow registration of most sub-objects once
14the main devlink object is itself registered. The newer ``devl_*`` APIs assume
15the devlink instance lock is already held. Drivers can take the instance
16lock by calling ``devl_lock()``. It is also held all callbacks of devlink
17netlink commands.
18
19Drivers are encouraged to use the devlink instance lock for their own needs.

44-----------------------------

46Each driver that implements ``devlink`` is expected to document what
47parameters, info versions, and other features it supports.
