All representors\nbelonging to the same E-Switch are created on the basis of the\nsingle PCI function and with current implementation each representor\nhas its own dedicated Infiniband device and operates within its\nown Infiniband context. It is proposed to provide representors\nas ports of the single Infiniband device and operate on the\nshared Infiniband context.\n\nmlx5_pci_probe() routine is planned to be extended to probe\nthe ports of found Infiniband devices. All active ports,\nbelonging to the same Infiniband device will use the signle\nshared Infiniband context of that device:\n - QP are created within shared context, with assigning to\n specified port\n - Verb flows are also created with specifying port index\n - Protection Domain is shared by all representors\n - Global Memory Regions Cache is shared by all representors,\n local ones are not (not in this patchset)\n - Shared Asynchronous Event Handler distributes events\n among the device ports (not in this patchset)\n - UAR mapping to user space is also shared (not in patchset)\n\t\t \nEach representor has its own attach network interface device,\ninterface name and index can be retrieved via IB device and\nport index, so the link control is performed via Netlink\nin the same way as in existing implementation.\n\nThis patchset also superseedes http://patches.dpdk.org/patch/50486/\n\t\t \nSigned-off-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com>\n\nViacheslav Ovsiienko (14):\n net/mlx5: add representor recognition on kernels 5.x\n net/mlx5: introduce multiport IB device shared structure\n net/mlx5: modify get ifindex routine for multiport IB\n net/mlx5: add getting IB ports number for multiport IB\n net/mlx5: add multiport IB device support to probing\n net/mlx5: add IB shared context alloc/free functions\n net/mlx5: switch to the names in the shared IB context\n net/mlx5: switch to the shared Protection Domain\n net/mlx5: switch to the shared context IB attributes\n net/mlx5: switch to the shared IB device context\n net/mlx5: provide IB port for the object being created\n net/mlx5: update install/uninstall int handler routines\n net/mlx5: update event handler for multiport IB devices\n net/mlx5: add source vport match to the ingress rules\n\n drivers/net/mlx5/Makefile | 10 +\n drivers/net/mlx5/meson.build | 4 +\n drivers/net/mlx5/mlx5.c | 549 +++++++++++++++++++++++++++----------\n drivers/net/mlx5/mlx5.h | 38 ++-\n drivers/net/mlx5/mlx5_ethdev.c | 241 ++++++++++------\n drivers/net/mlx5/mlx5_flow.c | 2 +\n drivers/net/mlx5/mlx5_flow_dv.c | 47 +++-\n drivers/net/mlx5/mlx5_flow_verbs.c | 7 +-\n drivers/net/mlx5/mlx5_mr.c | 4 +-\n drivers/net/mlx5/mlx5_nl.c | 101 ++++++-\n drivers/net/mlx5/mlx5_rxq.c | 41 +--\n drivers/net/mlx5/mlx5_socket.c | 4 +-\n drivers/net/mlx5/mlx5_stats.c | 22 +-\n drivers/net/mlx5/mlx5_trigger.c | 2 +-\n drivers/net/mlx5/mlx5_txq.c | 24 +-\n 15 files changed, 795 insertions(+), 301 deletions(-)" }
