This -means a subfunction has its own dedicated queues (txq, rxq, cq, eq). These -queues are neither shared nor stolen from the parent PCI function. - -When a subfunction is RDMA capable, it has its own QP1, GID table and rdma -resources neither shared nor stolen from the parent PCI function. - -A subfunction has a dedicated window in PCI BAR space that is not shared -with ther other subfunctions or the parent PCI function. This ensures that all -devices (netdev, rdma, vdpa etc.) of the subfunction accesses only assigned -PCI BAR space. - -A Subfunction supports eswitch representation through which it supports tc -offloads. The user configures eswitch to send/receive packets from/to -the subfunction port. - -Subfunctions share PCI level resources such as PCI MSI-X IRQs with -other subfunctions and/or with its parent PCI function. - -Example mlx5 software, system and device view:: - - _______ - | admin | - | user |---------- - |_______| | - | | - ____|____ __|______ _________________ - | | | | | | - | devlink | | tc tool | | user | - | tool | |_________| | applications | - |_________| | |_________________| - | | | | - | | | | Userspace - +---------|-------------|-------------------|----------|--------------------+ - | | +----------+ +----------+ Kernel - | | | netdev | | rdma dev | - | | +----------+ +----------+ - (devlink port add/del | ^ ^ - port function set) | | | - | | +---------------| - _____|___ | | _______|_______ - | | | | | mlx5 class | - | devlink | +------------+ | | drivers | - | kernel | | rep netdev | | |(mlx5_core,ib) | - |_________| +------------+ | |_______________| - | | | ^ - (devlink ops) | | (probe/remove) - _________|________ | | ____|________ - | subfunction | | +---------------+ | subfunction | - | management driver|----- | subfunction |---| driver | - | (mlx5_core) | | auxiliary dev | | (mlx5_core) | - |__________________| +---------------+ |_____________| - | ^ - (sf add/del, vhca events) | - | (device add/del) - _____|____ ____|________ - | | | subfunction | - | PCI NIC |---- activate/deactive events---->| host driver | - |__________| | (mlx5_core) | - |_____________| - -Subfunction is created using devlink port interface. - -- Change device to switchdev mode:: - - $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev - -- Add a devlink port of subfunction flaovur:: - - $ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 - pci/0000:06:00.0/32768: type eth netdev eth6 flavour pcisf controller 0 pfnum 0 sfnum 88 external false splittable false - function: - hw_addr 00:00:00:00:00:00 state inactive opstate detached - -- Show a devlink port of the subfunction:: - - $ devlink port show pci/0000:06:00.0/32768 - pci/0000:06:00.0/32768: type eth netdev enp6s0pf0sf88 flavour pcisf pfnum 0 sfnum 88 - function: - hw_addr 00:00:00:00:00:00 state inactive opstate detached - -- Delete a devlink port of subfunction after use:: - - $ devlink port del pci/0000:06:00.0/32768 - -mlx5 function attributes -======================== -The mlx5 driver provides a mechanism to setup PCI VF/SF function attributes in -a unified way for SmartNIC and non-SmartNIC. - -This is supported only when the eswitch mode is set to switchdev.
