The following commit has been merged in the master branch: commit 24a790da0ac4d9bcce2a9becc8799241716672f6 Merge: 32e31b78272ba0905c751a0f6ff6ab4c275a780e 142d93d12dc187f6a32aae2048da0c8230636b86 Author: Jakub Kicinski <kuba(a)kernel.org> Date: Thu Jan 28 16:57:19 2021 -0800 Merge tag 'mlx5-updates-2021-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5 subfunction support Parav Pandit says: This patchset introduces support for mlx5 subfunction (SF). A subfunction is a lightweight function that has a parent PCI function on which it is deployed. mlx5 subfunction has its own function capabilities and its own resources. 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 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 dedicated window in PCI BAR space that is not shared with the other subfunctions or parent PCI function. This ensures that all class devices of the subfunction accesses only assigned PCI BAR space. A Subfunction supports eswitch representation through which it supports tc offloads. User must configure eswitch to send/receive packets from/to subfunction port. Subfunctions share PCI level resources such as PCI MSI-X IRQs with their other subfunctions and/or with its parent PCI function. Subfunction support is discussed in detail in RFC [1] and [2]. RFC [1] and extension [2] describes requirements, design and proposed plumbing using devlink, auxiliary bus and sysfs for systemd/udev support. Functionality of this patchset is best explained using real examples further below. overview: -------- A subfunction can be created and deleted by a user using devlink port add/delete interface. A subfunction can be configured using devlink port function attribute before its activated. When a subfunction is activated, it results in an auxiliary device on the host PCI device where it is deployed. A driver binds to the auxiliary device that further creates supported class devices. example subfunction usage sequence: ----------------------------------- Change device to switchdev mode: $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev Add a devlink port of subfunction flavour: $ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 Configure mac address of the port function: $ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88 Now activate the function: $ devlink port function set ens2f0npf0sf88 state active Now use the auxiliary device and class devices: $ devlink dev show pci/0000:06:00.0 auxiliary/mlx5_core.sf.4 $ ip link show 127: ens2f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 24:8a:07:b3:d1:12 brd ff:ff:ff:ff:ff:ff altname enp6s0f0np0 129: p0sf88: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 00:00:00:00:88:88 brd ff:ff:ff:ff:ff:ff $ rdma dev show 43: rdmap6s0f0: node_type ca fw 16.29.0550 node_guid 248a:0703:00b3:d112 sys_image_guid 248a:0703:00b3:d112 44: mlx5_0: node_type ca fw 16.29.0550 node_guid 0000:00ff:fe00:8888 sys_image_guid 248a:0703:00b3:d112 After use inactivate the function: $ devlink port function set ens2f0npf0sf88 state inactive Now delete the subfunction port: $ devlink port del ens2f0npf0sf88 [1] https://lore.kernel.org/netdev/20200519092258.GF4655@nanopsycho/ [2] https://marc.info/?l=linux-netdev&m=158555928517777&w=2 ================= * tag 'mlx5-updates-2021-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Add devlink subfunction port documentation devlink: Extend devlink port documentation for subfunctions devlink: Add devlink port documentation net/mlx5: SF, Port function state change support net/mlx5: SF, Add port add delete functionality net/mlx5: E-switch, Add eswitch helpers for SF vport net/mlx5: E-switch, Prepare eswitch to handle SF vport net/mlx5: SF, Add auxiliary device driver net/mlx5: SF, Add auxiliary device support net/mlx5: Introduce vhca state event notifier devlink: Support get and set state of port function devlink: Support add and delete devlink port devlink: Introduce PCI SF port flavour and port attribute devlink: Prepare code to fill multiple port function attributes ==================== Link: https://lore.kernel.org/r/20210122193658.282884-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> diff --combined drivers/net/ethernet/mellanox/mlx5/core/Makefile index d44f5f6ee449,40ed31574c80..f61ee7110243 --- a/drivers/net/ethernet/mellanox/mlx5/core/Makefile +++ b/drivers/net/ethernet/mellanox/mlx5/core/Makefile @@@ -16,8 -16,7 +16,8 @@@ mlx5_core-y := main.o cmd.o debugfs.o f transobj.o vport.o sriov.o fs_cmd.o fs_core.o pci_irq.o \ fs_counters.o rl.o lag.o dev.o events.o wq.o lib/gid.o \ lib/devcom.o lib/pci_vsc.o lib/dm.o diag/fs_tracepoint.o \ - diag/fw_tracer.o diag/crdump.o devlink.o diag/rsc_dump.o fw_reset.o + diag/fw_tracer.o diag/crdump.o devlink.o diag/rsc_dump.o \ + fw_reset.o qos.o # # Netdev basic @@@ -26,8 -25,7 +26,8 @@@ mlx5_core-$(CONFIG_MLX5_CORE_EN) += en_ en_tx.o en_rx.o en_dim.o en_txrx.o en/xdp.o en_stats.o \ en_selftest.o en/port.o en/monitor_stats.o en/health.o \ en/reporter_tx.o en/reporter_rx.o en/params.o en/xsk/pool.o \ - en/xsk/setup.o en/xsk/rx.o en/xsk/tx.o en/devlink.o en/ptp.o + en/xsk/setup.o en/xsk/rx.o en/xsk/tx.o en/devlink.o en/ptp.o \ + en/qos.o en/trap.o # # Netdev extra @@@ -88,3 -86,12 +88,12 @@@ mlx5_core-$(CONFIG_MLX5_SW_STEERING) + steering/dr_ste_v0.o \ steering/dr_cmd.o steering/dr_fw.o \ steering/dr_action.o steering/fs_dr.o + # + # SF device + # + mlx5_core-$(CONFIG_MLX5_SF) += sf/vhca_event.o sf/dev/dev.o sf/dev/driver.o + + # + # SF manager + # + mlx5_core-$(CONFIG_MLX5_SF_MANAGER) += sf/cmd.o sf/hw_table.o sf/devlink.o diff --combined drivers/net/ethernet/mellanox/mlx5/core/devlink.c index b23b54814356,7712311e8684..aa76a6e0dae8 --- a/drivers/net/ethernet/mellanox/mlx5/core/devlink.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/devlink.c @@@ -7,6 -7,8 +7,8 @@@ #include "fw_reset.h" #include "fs_core.h" #include "eswitch.h" + #include "sf/dev/dev.h" + #include "sf/sf.h" static int mlx5_devlink_flash_update(struct devlink *devlink, struct devlink_flash_update_params *params, @@@ -127,6 -129,17 +129,17 @@@ static int mlx5_devlink_reload_down(str struct netlink_ext_ack *extack) { struct mlx5_core_dev *dev = devlink_priv(devlink);
