devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares. Example: DEV=pci/0000:08:00.0 $ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \ tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0 $ devlink port function rate set $DEV/vfs_group \ tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0 Example usage with ynl: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"rate-tc-index": 0, "rate-tc-bw": 50}, {"rate-tc-index": 1, "rate-tc-bw": 50}, {"rate-tc-index": 2, "rate-tc-bw": 0}, {"rate-tc-index": 3, "rate-tc-bw": 0}, {"rate-tc-index": 4, "rate-tc-bw": 0}, {"rate-tc-index": 5, "rate-tc-bw": 0}, {"rate-tc-index": 6, "rate-tc-bw": 0}, {"rate-tc-index": 7, "rate-tc-bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'rate-tc-bw': 50, 'rate-tc-index': 0}, {'rate-tc-bw': 50, 'rate-tc-index': 1}, {'rate-tc-bw': 0, 'rate-tc-index': 2}, {'rate-tc-bw': 0, 'rate-tc-index': 3}, {'rate-tc-bw': 0, 'rate-tc-index': 4}, {'rate-tc-bw': 0, 'rate-tc-index': 5}, {'rate-tc-bw': 0, 'rate-tc-index': 6}, {'rate-tc-bw': 0, 'rate-tc-index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250629142138.361537-3-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares.

devlink: Acquire device lock during reload command Device drivers register with devlink from their probe routines (under the device lock) by acquiring the devlink instance lock and calling devl_register(). Drivers that support a devlink reload usually implement the reload_{down, up}() operations in a similar fashion to their remove and probe routines, respectively. However, while the remove and probe routines are invoked with the device lock held, the reload operations are only invoked with the devlink instance lock held. It is therefore impossible for drivers to acquire the device lock from their reload operations, as this would result in lock inversion. The motivating use case for invoking the reload operations with the device lock held is in mlxsw which needs to trigger a PCI reset as part of the reload. The driver cannot call pci_reset_function() as this function acquires the device lock. Instead, it needs to call __pci_reset_function_locked which expects the device lock to be held. To that end, adjust devlink to always acquire the device lock before the devlink instance lock when performing a reload. Do that when reload is explicitly triggered by user space by specifying the 'DEVLINK_NL_FLAG_NEED_DEV_LOCK' flag in the pre_doit and post_doit operations of the reload command. A previous patch already handled the case where reload is invoked as part of netns dismantle.

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares.
