A SF netdev supports E-Switch representation\noffload similar to existing PF and VF representors. A SF shares PCI\nlevel resources with other SFs and/or with its parent PCI function.\n\nFrom SmartNIC perspective, when PCI device is shared for multi-host,\nrepresentors for host controller and host PF is required.\n\nThis patch set introduces new representor types in addtion to existing\nVF representor. Syntax:\n\n[[c#]pf#]vf#: VF port representor/s from controller/pf\n[[c#]pf#]sf#: SF port representor/s from controller/pf\n#: VF representor - for backwards compatibility\n\n\"#\" is number instance, list or range, valid examples:\n 1, [1,3,5], [0-3], [0,2-4,6]\n\nFor backward compatibility, this patch also introduces new netdev\ncapability to indicate the capability of supportting SF representor.\n\nVersion history:\n RFC:\n \tinitial version [2]\n V2:\n - separate patch for represnetor infrastructure, controller, pf and\n sf.\n - replace representor ID macro with functions:\n rte_eth_representor_id_encode()\n rte_eth_representor_id_parse()\n - new patch to allow devargs with same PCI BDF but different\n representors.\n - other minor code updates according to comments, thanks Andrew!\n - update document\n V3:\n - improve probing of allowed devargs with same name.\n - parse single word of kvargs as key.\n - update kvargs test cases.\n V4:\n - split first representor refactor patch into\n 1: add representor type\n 2: refector representor list parsing\n - push the patch supporting multi-devargs for same device.\n V5:\n - add comments for parsing functions\n - update switch_representation.rst - Thanks Ajit\n V6:\n - split representor types into different patches, move to\n rte_ethdev.h\n - improvements of rte_eth_devargs_process_list() according to\n Andrew's suggestion\n - fixed PF probe failure for Intel i40e\n - replace ethdev SF capability with rte_eth_representor_info_get()\n - add new ethdev ops api to get representor info from PMD\n - replace representor ID encode/decode with conversion from\n representor info\n - change ethdev representor iterator to use new ID encoding\n V7:\n - error on duplicated representor argument:\n DBDF,representor=a,representor=b\n - fix pf representor type parsing\n - other small fixes suggested by Andrew.\n V8:\n \t- remove the \"ignore\" hint from pmd representor info\n \t- changed representor_id type in representor info to u32\n \t- rename rte_eth_representor_id_convert() to ..._get()\n \t- other small fixes suggested by Andrew\n \n\n\n[1] SubFunction in kernel:\nhttps://lore.kernel.org/netdev/20201112192424.2742-1-parav@nvidia.com/\n\n[2] RFC:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=14376\n\n[3] V2:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=14559\n\n[4] V3:\n1 http://patchwork.dpdk.org/patch/86460/\n2 http://patchwork.dpdk.org/patch/86461/\n3 http://patchwork.dpdk.org/patch/86462/\n4 http://patchwork.dpdk.org/patch/86463/\n5 http://patchwork.dpdk.org/patch/86464/\n6 http://patchwork.dpdk.org/patch/86465/\n7 http://patchwork.dpdk.org/patch/86467/\n8 http://patchwork.dpdk.org/patch/86466/\n9 http://patchwork.dpdk.org/patch/86468/\n\n[5] V4:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=14809\n\n[6] V5:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=14834\n\n[7] V6:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=15258\n\n[8] v7:\nhttp://patchwork.dpdk.org/project/dpdk/list/?series=15441\n\nXueming Li (9):\n ethdev: introduce representor type\n ethdev: support representor port list\n ethdev: support new VF representor syntax\n ethdev: support sub function representor\n ethdev: support PF index in representor\n ethdev: support multi-host in representor\n ethdev: new API to get representor info\n ethdev: representor iterator compare complete info\n kvargs: update parser to support lists\n\n app/test/test_kvargs.c | 46 ++++-\n config/rte_config.h | 1 +\n doc/guides/prog_guide/poll_mode_drv.rst | 18 +-\n .../prog_guide/switch_representation.rst | 35 ++--\n drivers/net/bnxt/bnxt_ethdev.c | 7 +\n drivers/net/enic/enic_ethdev.c | 6 +\n drivers/net/i40e/i40e_ethdev.c | 7 +\n drivers/net/ixgbe/ixgbe_ethdev.c | 7 +\n drivers/net/mlx5/linux/mlx5_os.c | 11 ++\n lib/librte_ethdev/ethdev_driver.h | 50 +++++-\n lib/librte_ethdev/ethdev_private.c | 169 ++++++++++++------\n lib/librte_ethdev/ethdev_private.h | 3 -\n lib/librte_ethdev/rte_class_eth.c | 40 +++--\n lib/librte_ethdev/rte_ethdev.c | 113 +++++++++++-\n lib/librte_ethdev/rte_ethdev.h | 61 +++++++\n lib/librte_ethdev/version.map | 4 +\n lib/librte_kvargs/rte_kvargs.c | 101 ++++++++---\n 17 files changed, 554 insertions(+), 125 deletions(-)" }
