devlink: extend devlink_param *set pointer

2024-04-22T20:05:19Z

Extend devlink_param *set function pointer to take extack as a param. Sometimes it is needed to pass information to the end user from set function. It is more proper to use for that netlink instead of passing message to dmesg. Reviewed-by: Jiri Pirko Reviewed-by: Przemek Kitszel Signed-off-by: Mateusz Polchlopek Signed-off-by: Tony Nguyen

devlink: protect devlink param list by instance lock

2023-01-27T12:32:02Z

Commit 1d18bb1a4ddd ("devlink: allow registering parameters after the instance") as the subject implies introduced possibility to register devlink params even for already registered devlink instance. This is a bit problematic, as the consistency or params list was originally secured by the fact it is static during devlink lifetime. So in order to protect the params list, take devlink instance lock during the params operations. Introduce unlocked function variants and use them in drivers in locked context. Put lock assertions to appropriate places.

nfp: add devlink param infrastructure

2019-09-10T16:29:27Z

Register devlink parameters for driver use. Subsequent patches will add support for specific parameters. In order to support devlink parameters, the management firmware needs to be able to lookup and set hwinfo keys.
