The following changes since commit ded5c1a16ec69bb815f2b7d9ea4028913ebffca4: Merge branch 'tools-ynl-gen-code-gen-improvements-before-ethtool' (2023-06-09 14:40:33 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git tags/mlx5-updates-2023-06-09 for you to fetch changes up to 978015f7ef9240acfb078f4c1c0d79459b42f951: net/mlx5e: Remove a useless function call (2023-06-09 18:40:53 -0700) ---------------------------------------------------------------- mlx5-updates-2023-06-09 1) Embedded CPU Virtual Functions 2) Lightweight local SFs Daniel Jurgens says: ==================== Embedded CPU Virtual Functions This series enables the creation of virtual functions on Bluefield (the embedded CPU platform). Embedded CPU virtual functions (EC VFs). EC VF creation, deletion and management interfaces are the same as those for virtual functions in a server with a Connect-X NIC. When using EC VFs on the ARM the creation of virtual functions on the host system is still supported. Host VFs eswitch vports occupy a range of 1..max_vfs, the EC VF vport range is max_vfs+1..max_ec_vfs. Every function (PF, ECPF, VF, EC VF, and subfunction) has a function ID associated with it. Prior to this series the function ID and the eswitch vport were the same. That is no longer the case, the EC VF function ID range is 1..max_ec_vfs. When querying or setting the capabilities of an EC VF function an new bit must be set in the query/set HCA cap structure. This is a high level overview of the changes made: - Allocate vports for EC VFs if they are enabled. - Create representors and devlink ports for the EC VF vports. - When querying/setting HCA caps by vport break the assumption that function ID is the same a vport number and adjust accordingly. - Create a new type of page, so that when SRIOV on the ARM is disabled, but remains enabled on the host, the driver can wait for the correct pages. - Update SRIOV code to support EC VF creation/deletion. =================== Lightweight local SFs: Last 3 patches form Shay Drory: SFs are heavy weight and by default they come with the full package of ConnectX features. Usually users want specialized SFs for one specific purpose and using devlink users will almost always override the set of advertises features of an SF and reload it. Shay Drory says: ================ In order to avoid the wasted time and resources on the reload, local SFs will probe without any auxiliary sub-device, so that the SFs can be configured prior to its full probe. The defaults of the enable_* devlink params of these SFs are set to false. Usage example: Create SF: $ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11 $ devlink port function set pci/0000:08:00.0/32768 \ hw_addr 00:00:00:00:00:11 state active Enable ETH auxiliary device: $ devlink dev param set auxiliary/mlx5_core.sf.1 \ name enable_eth value true cmode driverinit Now, in order to fully probe the SF, use devlink reload: $ devlink dev reload auxiliary/mlx5_core.sf.1 At this point the user have SF devlink instance with auxiliary device for the Ethernet functionality only. ================ ---------------------------------------------------------------- Christophe JAILLET (1): net/mlx5e: Remove a useless function call Daniel Jurgens (11): net/mlx5: Simplify unload all rep code net/mlx5: mlx5_ifc updates for embedded CPU SRIOV net/mlx5: Enable devlink port for embedded cpu VF vports net/mlx5: Update vport caps query/set for EC VFs net/mlx5: Add management of EC VF vports net/mlx5: Add/remove peer miss rules for EC VFs net/mlx5: Add new page type for EC VF pages net/mlx5: Use correct vport when restoring GUIDs net/mlx5: Query correct caps for min msix vectors net/mlx5: Update SRIOV enable/disable to handle EC/VFs net/mlx5: Set max number of embedded CPU VFs Shay Drory (3): net/mlx5: Split function_setup() to enable and open functions net/mlx5: Move esw multiport devlink param to eswitch code net/mlx5: Light probe local SFs .../ethernet/mellanox/mlx5/switchdev.rst | 20 ++ drivers/net/ethernet/mellanox/mlx5/core/debugfs.c | 1 + drivers/net/ethernet/mellanox/mlx5/core/dev.c | 16 ++ drivers/net/ethernet/mellanox/mlx5/core/devlink.c | 54 ++---- .../ethernet/mellanox/mlx5/core/en/tc/post_act.c | 4 +- .../ethernet/mellanox/mlx5/core/esw/devlink_port.c | 8 +- drivers/net/ethernet/mellanox/mlx5/core/eswitch.c | 174 +++++++++++++++-- drivers/net/ethernet/mellanox/mlx5/core/eswitch.h | 13 ++ .../ethernet/mellanox/mlx5/core/eswitch_offloads.c | 102 +++++----- drivers/net/ethernet/mellanox/mlx5/core/health.c | 24 ++- drivers/net/ethernet/mellanox/mlx5/core/main.c | 209 +++++++++++++++++---- .../net/ethernet/mellanox/mlx5/core/mlx5_core.h | 35 +++- .../net/ethernet/mellanox/mlx5/core/pagealloc.c | 11 +- drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c | 16 +- .../ethernet/mellanox/mlx5/core/sf/dev/driver.c | 15 +- drivers/net/ethernet/mellanox/mlx5/core/sriov.c | 46 ++++- drivers/net/ethernet/mellanox/mlx5/core/vport.c | 19 +- include/linux/mlx5/driver.h | 7 + include/linux/mlx5/mlx5_ifc.h | 11 +- include/linux/mlx5/vport.h | 2 +- 20 files changed, 610 insertions(+), 177 deletions(-)
