devlink: Improve the port attributes description

2025-01-03T01:10:57Z

Current PF number description is vague, sometimes interpreted as some PF index. VF number in the PCI specification starts at 1; however in kernel, it starts at 0 for representor model. Improve the description of devlink port attributes PF, VF and SF numbers with these details.

devlink: Constify the 'table_ops' parameter of devl_dpipe_table_register()

2024-06-05T09:24:57Z

"struct devlink_dpipe_table_ops" only contains some function pointers. Update "struct devlink_dpipe_table" and the 'table_ops' parameter of devl_dpipe_table_register() so that structures in drivers can be constified. Constifying these structures will move some data to a read-only section, so increase overall security.

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: Support setting max_io_eqs

2024-04-08T13:10:45Z

Many devices send event notifications for the IO queues, such as tx and rx queues, through event queues. Enable a privileged owner, such as a hypervisor PF, to set the number of IO event queues for the VF and SF during the provisioning stage. example: Get maximum IO event queues of the VF device:: $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 10 Set maximum IO event queues of the VF device:: $ devlink port function set pci/0000:06:00.0/2 max_io_eqs 32 $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 32 Reviewed-by: Jiri Pirko Reviewed-by: Shay Drory Signed-off-by: Parav Pandit Signed-off-by: David S.
