A SF netdev supports eswitch representation offload similar to existing PF and VF representors. A SF shares PCI level resources with other SFs and/or with its parent PCI function. >From SmartNIC perspective, when PCI device is shared for multi-host, representors for host controller and host PF is required. This patch set introduces new representor types in addtion to existing VF representor. Syntax: [[c#]pf#]vf#: VF port representor/s from controller/pf [[c#]pf#]sf#: SF port representor/s from controller/pf #: VF representor - for backwards compatibility "#" is number instance, list or range, valid examples: 1, [1,3,5], [0-3], [0,2-4,6] For backward compatibility, this patch also introduces new netdev capability to indicate the capability to support SF representor. Version history: RFC: initial version [2] V2: - separate patch for represnetor infrastructure, controller, pf and sf. - replace representor ID macro with functions: rte_eth_representor_id_encode() rte_eth_representor_id_parse() - new patch to allow devargs with same PCI BDF but different representors. - other minor code updates according to comments, thanks Andrew! - update document [1] SubFunction in kernel: https://lore.kernel.org/netdev/20201112192424.2742-1-parav@nvidia.com/ [2] RFC: http://patchwork.dpdk.org/project/dpdk/list/?series=14376 Xueming Li (9): ethdev: refactor representor infrastructure ethdev: support new VF representor syntax ethdev: support sub function representor ethdev: support PF index in representor ethdev: support multi-host representor devarg: change reprsentor ID to bitmap ethdev: capability of new representor syntax kvargs: update parser for new representor syntax eal: allow PCI device with different representors config/rte_config.h | 1 + doc/guides/prog_guide/poll_mode_drv.rst | 8 +- drivers/net/bnxt/bnxt_ethdev.c | 12 +++ drivers/net/bnxt/bnxt_reps.c | 3 +- drivers/net/enic/enic_ethdev.c | 7 ++ drivers/net/enic/enic_vf_representor.c | 3 +- drivers/net/i40e/i40e_ethdev.c | 8 ++ drivers/net/i40e/i40e_vf_representor.c | 3 +- drivers/net/ixgbe/ixgbe_ethdev.c | 8 ++ drivers/net/ixgbe/ixgbe_vf_representor.c | 3 +- drivers/net/mlx5/linux/mlx5_os.c | 15 ++- lib/librte_eal/common/eal_common_bus.c | 25 +++++ lib/librte_ethdev/ethdev_private.c | 128 ++++++++++++++--------- lib/librte_ethdev/ethdev_private.h | 3 - lib/librte_ethdev/rte_class_eth.c | 40 +++++-- lib/librte_ethdev/rte_ethdev.c | 31 +++++- lib/librte_ethdev/rte_ethdev.h | 2 + lib/librte_ethdev/rte_ethdev_driver.h | 64 ++++++++++++ lib/librte_ethdev/version.map | 2 + lib/librte_kvargs/rte_kvargs.c | 83 ++++++++++----- 20 files changed, 348 insertions(+), 101 deletions(-) -- 2.25.1
