ice: Add support for devlink local_forwarding param

2024-07-11T17:53:57+00:00

Add support for driver-specific devlink local_forwarding param. Supported values are "enabled", "disabled" and "prioritized". Default configuration is set to "enabled". Add documentation in networking/devlink/ice.rst. In previous generations of Intel NICs the transmit scheduler was only limited by PCIe bandwidth when scheduling/assigning hairpin-bandwidth between VFs. Changes to E810 HW design introduced scheduler limitation, so that available hairpin-bandwidth is bound to external port speed. In order to address this limitation and enable NFV services such as "service chaining" a knob to adjust the scheduler config was created. Driver can send a configuration message to the FW over admin queue and internal FW logic will reconfigure HW to prioritize and add more BW to VF to VF traffic. An end result, for example, 10G port will no longer limit hairpin-bandwidth to 10G and much higher speeds can be achieved. Devlink local_forwarding param set to "prioritized" enables higher hairpin-bandwitdh on related PFs. Configuration is applicable only to 8x10G and 4x25G cards. Changing local_forwarding configuration will trigger CORER reset in order to take effect. Example command to change current value: devlink dev param set pci/0000:b2:00.3 name local_forwarding \ value prioritized \ cmode runtime Co-developed-by: Michal Wilczynski Signed-off-by: Michal Wilczynski Reviewed-by: Przemek Kitszel Signed-off-by: Pawel Kaminski Signed-off-by: Wojciech Drewek Tested-by: Rafal Romanowski Signed-off-by: Tony Nguyen

octeontx2-pf: Add ucast filter count configurability via devlink.

2024-06-21T10:28:47+00:00

The existing method of reserving unicast filter count leads to wasted MCAM entries if the functionality is not used or fewer entries are used. Furthermore, the amount of MCAM entries differs amongst Octeon SoCs. We implemented a means to adjust the UC filter count via devlink, allowing for better use of MCAM entries across Netdev apps. commands: To get the current unicast filter count # devlink dev param show pci/0002:02:00.0 name unicast_filter_count To change/set the unicast filter count # devlink dev param set pci/0002:02:00.0 name unicast_filter_count value 5 cmode runtime Signed-off-by: Sai Krishna Reviewed-by: Simon Horman Signed-off-by: David S.

devlink: Support setting max_io_eqs

2024-04-08T13:10:45+00:00

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.
