2024-04-22devlink: extend devlink_param *set pointerMateusz Polchlopek1-1/+2
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.

2023-10-20qed: devlink health: use retained error fmsg APIPrzemek Kitszel1-3/+3
Drop unneeded error checking. devlink_fmsg_*() family of functions is now retaining errors, so there is no need to check for them after each call.

2023-01-27qed: remove pointless call to devlink_param_driverinit_value_set()Jiri Pirko1-6/+0
devlink_param_driverinit_value_set() call makes sense only for " driverinit" params. However here, the param is "runtime". devlink_param_driverinit_value_set() returns -EOPNOTSUPP in such case and does not do anything. So remove the pointless call to devlink_param_driverinit_value_set() entirely.

2022-11-30net: devlink: let the core report the driver name instead of the driversVincent Mailhol1-4/+0
The driver name is available in device_driver::name. Right now, drivers still have to report this piece of information themselves in their devlink_ops::info_get callback function. In order to factorize code, make devlink_nl_info_fill() add the driver name attribute. Now that the core sets the driver name attribute, drivers are not supposed to call devlink_info_driver_name_put() anymore. Remove devlink_info_driver_name_put() and clean-up all the drivers using this function in their callback.

2021-09-22devlink: Make devlink_register to be voidLeon Romanovsky1-6/+1
devlink_register() can't fail and always returns success, but all drivers are obligated to check returned status anyway. This adds a lot of boilerplate code to handle impossible flow. Make devlink_register() void and simplify the drivers that use that API call.

2021-08-09devlink: Set device as early as possibleLeon Romanovsky1-2/+3
All kernel devlink implementations call to devlink_alloc() during initialization routine for specific device which is used later as a parent device for devlink_register(). Such late device assignment causes to the situation which requires us to call to device_register() before setting other parameters, but that call opens devlink to the world and makes accessible for the netlink users. Any attempt to move devlink_register() to be the last call generates the following error due to access to the devlink->dev pointer. [ 8.758862] devlink_nl_param_fill+0x2e8/0xe50 [ 8.760305] devlink_param_notify+0x6d/0x180 [ 8.760435] __devlink_params_register+0x2f1/0x670 [ 8.760558] devlink_params_register+0x1e/0x20 The simple change of API to set devlink device in the devlink_alloc() instead of devlink_register() fixes all this above and ensures that prior to call to devlink_register() everything already set.

Management is a firmware responsible for link configuration and various control plane features. Its permanent and resides in NVM. Running FW (or fastpath FW) is an embedded microprogram implementing all the packet processing, offloads, etc. This FW is being loaded on each start by the driver from FW binary blob. The base device specific structure (qed_dev_info) was not directly available to the base driver before. Thus, here we create and store a private copy of this structure in qed_dev root object to access the data.

Devlink instance lifecycle was linked to qed_dev object, that caused devlink to be recreated on each recovery. Changing it by making higher level driver (qede) responsible for its life. This way devlink now survives recoveries. qede now stores devlink structure pointer as a part of its device object, devlink private data contains a linkage structure, qed_devlink.
