2024-07-11ice: Add support for devlink local_forwarding paramPawel Kaminski
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 <michal.wilczynski@intel.com> Signed-off-by: Michal Wilczynski <michal.wilczynski@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Signed-off-by: Pawel Kaminski <pawel.kaminski@intel.com> Signed-off-by: Wojciech Drewek <wojciech.drewek@intel.com> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2023-08-27devlink: Expose port function commands to control IPsec packet offloadsDima Chumak
Expose port function commands to enable / disable IPsec packet offloads, this is used to control the port IPsec capabilities. When IPsec packet is disabled for a function of the port (default), function cannot offload IPsec packet operations (encapsulation and XFRM policy offload). When enabled, IPsec packet operations can be offloaded by the function of the port, which includes crypto operation (Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy offload.

A new check for the tx devlink health reporter is introduced for determining when the PTP port timestamping SQ is considered unhealthy. If there are enough CQEs considered never to be delivered, the space that can be utilized on the SQ decreases significantly, impacting performance and usability of the SQ. The health reporter is triggered when the number of likely never delivered port timestamping CQEs that utilize the space of the PTP SQ is greater than 93.75% of the total capacity of the SQ. A devlink health reporter recover method is also provided for this specific TX error context that restarts the PTP SQ.

The new mode will allow in the future a decrease in the memory used by the driver and advanced features that aren't possible today. This represents a big change in the current E-Switch implantation in mlx5. Currently, by default, each E-Switch manager manages its E-Switch. Steering rules in each E-Switch can only forward traffic to the native physical port associated with that E-Switch. While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort Eswitch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default. 2) From Jiri: Improvements and fixes for mlx5 netdev's devlink logic 2.1) Cleanups related to mlx5's devlink port logic 2.2) Move devlink port registration to be done before netdev alloc 2.3) Create auxdev devlink instance in the same ns as parent devlink 2.4) Suspend auxiliary devices only in case of PCI device suspend * tag 'mlx5-updates-2023-02-10' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Suspend auxiliary devices only in case of PCI device suspend net/mlx5: Remove "recovery" arg from mlx5_load_one() function net/mlx5e: Create auxdev devlink instance in the same ns as parent devlink net/mlx5e: Move devlink port registration to be done before netdev alloc net/mlx5e: Move dl_port to struct mlx5e_dev net/mlx5e: Replace usage of mlx5e_devlink_get_dl_port() by netdev->devlink_port net/mlx5e: Pass mdev to mlx5e_devlink_port_register() net/mlx5: Remove outdated comment net/mlx5e: TC, Remove redundant parse_attr argument net/mlx5e: Use a simpler comparison for uplink rep net/mlx5: Lag, Add single RDMA device in multiport mode net/mlx5: Lag, set different uplink vport metadata in multiport eswitch mode net/mlx5: E-Switch, rename bond update function to be reused net/mlx5e: TC, Add peer flow in mpesw mode net/mlx5: Lag, Control MultiPort E-Switch single FDB mode ==================== Link: https://lore.kernel.org/r/20230214221239.159033-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort E-Switch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default.

2022-12-07devlink: Expose port function commands to control migratableShay Drory
Expose port function commands to enable / disable migratable capability, this is used to set the port function as migratable. Live migration is the process of transferring a live virtual machine from one physical host to another without disrupting its normal operation. In order for a VM to be able to perform LM, all the VM components must be able to perform migration. e.g.: to be migratable. In order for VF to be migratable, VF must be bound to VFIO driver with migration support. When migratable capability is enabled for a function of the port, the device is making the necessary preparations for the function to be migratable, which might include disabling features which cannot be migrated. Example of LM with migratable function configuration: Set migratable of the VF's port function. $ 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 migratable disable $ devlink port function set pci/0000:06:00.0/2 migratable enable $ 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 migratable enable Bind VF to VFIO driver with migration support: $ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/unbind $ echo mlx5_vfio_pci > /sys/bus/pci/devices/0000:08:00.0/driver_override $ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/bind Attach VF to the VM.

2022-12-07devlink: Expose port function commands to control RoCEShay Drory
Expose port function commands to enable / disable RoCE, this is used to control the port RoCE device capabilities. When RoCE is disabled for a function of the port, function cannot create any RoCE specific resources (e.g GID table). It also saves system memory utilization. For example disabling RoCE enable a VF/SF saves 1 Mbytes of system memory per function. Example of a PCI VF port which supports function configuration: Set RoCE of the VF's port function. $ 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 roce enable $ devlink port function set pci/0000:06:00.0/2 roce disable $ 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 roce disable Signed-off-by: Shay Drory <shayd@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-11-30devlink: support directly reading from region memoryJacob Keller
To read from a region, user space must currently request a new snapshot of the region and then read from that snapshot. This can sometimes be overkill if user space only reads a tiny portion. They first create the snapshot, then request a read, then destroy the snapshot. For regions which have a single underlying "contents", it makes sense to allow supporting direct reading of the region data. Extend the DEVLINK_CMD_REGION_READ to allow direct reading from a region if requested via the new DEVLINK_ATTR_REGION_DIRECT. If this attribute is set, then perform a direct read instead of using a snapshot. Direct read is mutually exclusive with DEVLINK_ATTR_REGION_SNAPSHOT_ID, and care is taken to ensure that we reject commands which provide incorrect attributes. Regions must enable support for direct read by implementing the .read() callback function. If a region does not support such direct reads, a suitable extended error message is reported.
