2023-02-16Merge branch 'adding-sparx5-es0-vcap-support'Paolo Abeni18-743/+2749
Steen Hegelund says: ==================== Adding Sparx5 ES0 VCAP support This provides the Egress Stage 0 (ES0) VCAP (Versatile Content-Aware Processor) support for the Sparx5 platform. The ES0 VCAP is an Egress Access Control VCAP that uses frame keyfields and previously classified keyfields to add, rewrite or remove VLAN tags on the egress frames, and is therefore often referred to as the rewriter. The ES0 VCAP also supports trapping frames to the host. The ES0 VCAP has 1 lookup accessible with this chain id: - chain 10000000: ES0 Lookup 0 The ES0 VCAP does not do traffic classification to select a keyset, but it does have two keysets that can be used on all traffic. For now only the ISDX keyset is used. The ES0 VCAP can match on an ISDX key (Ingress Service Index) as one of the frame metadata keyfields, similar to the ES2 VCAP. The ES0 VCAP uses external counters in the XQS (statistics) group. ==================== Link: https://lore.kernel.org/r/20230214104049.1553059-1-steen.hegelund@microchip.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-02-10 1) From Roi and Mark: MultiPort eswitch support MultiPort E-Switch builds on newer hardware's capabilities and introduces a mode where a single E-Switch is used and all the vports and physical ports on the NIC are connected to it. The new mode will allow in the future a decrease in the memory used by the driver and advanced features that aren't possible today. This represents a big change in the current E-Switch implantation in mlx5. Currently, by default, each E-Switch manager manages its E-Switch. Steering rules in each E-Switch can only forward traffic to the native physical port associated with that E-Switch. While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort Eswitch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default. 2) From Jiri: Improvements and fixes for mlx5 netdev's devlink logic 2.1) Cleanups related to mlx5's devlink port logic 2.2) Move devlink port registration to be done before netdev alloc 2.3) Create auxdev devlink instance in the same ns as parent devlink 2.4) Suspend auxiliary devices only in case of PCI device suspend * tag 'mlx5-updates-2023-02-10' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Suspend auxiliary devices only in case of PCI device suspend net/mlx5: Remove "recovery" arg from mlx5_load_one() function net/mlx5e: Create auxdev devlink instance in the same ns as parent devlink net/mlx5e: Move devlink port registration to be done before netdev alloc net/mlx5e: Move dl_port to struct mlx5e_dev net/mlx5e: Replace usage of mlx5e_devlink_get_dl_port() by netdev->devlink_port net/mlx5e: Pass mdev to mlx5e_devlink_port_register() net/mlx5: Remove outdated comment net/mlx5e: TC, Remove redundant parse_attr argument net/mlx5e: Use a simpler comparison for uplink rep net/mlx5: Lag, Add single RDMA device in multiport mode net/mlx5: Lag, set different uplink vport metadata in multiport eswitch mode net/mlx5: E-Switch, rename bond update function to be reused net/mlx5e: TC, Add peer flow in mpesw mode net/mlx5: Lag, Control MultiPort E-Switch single FDB mode ==================== Link: https://lore.kernel.org/r/20230214221239.159033-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.

Alex Elder says: ==================== net: ipa: define GSI register fields differently Now that we have "reg" definitions in place to define GSI register offsets, add the definitions for the fields of GSI registers that have them. There aren't many differences between versions, but a few fields are present only in some versions of IPA, so additional "gsi_reg-vX.Y.c" files are created to capture such differences. As in the previous series, these files are created as near-copies of existing files just before they're needed to represent these differences. The first patch adds files for IPA v4.0, v4.5, and v4.9; the fifth patch adds a file for IPA v4.11. Note that the first and fifth patch cause some checkpatch warnings because they align some continued lines with an open parenthesis that at the fourth column. ==================== Link: https://lore.kernel.org/r/20230213162229.604438-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-15net: ipa: define fields for remaining GSI registersAlex Elder8-102/+452
Define field IDs for the remaining GSI registers, and populate the register definition files accordingly. Use the reg_*() functions to access field values for those regiters, and get rid of the previous field definition constants.

2023-02-15net: ipa: add "gsi_v4.11.c"Alex Elder4-2/+256
The next patch adds a GSI register field that is only valid starting at IPA v4.11. Create "gsi_v4.11.c" from "gsi_v4.9.c", changing only the name of the public regs structure it defines. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-15net: ipa: define fields for event-ring related registersAlex Elder7-40/+122
Define field IDs for the EV_CH_E_CNTXT_0 and EV_CH_E_CNTXT_8 GSI registers, and populate the register definition files accordingly. Use the reg_*() functions to access field values for those regiters, and get rid of the previous field definition constants. The remaining EV_CH_E_CNTXT_* registers are written with full 32-bit values (and have no fields). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-15net: ipa: define more fields for GSI registersAlex Elder7-40/+130
Beyond the CH_C_QOS register, two other registers whose offset is related to channel number have fields within them. Define the fields within the CH_C_CNTXT_0 GSI register, using an enumerated type to identify the register's fields, and define an array of field masks to use for that register's reg structure. For the CH_C_CNTXT_1 GSI register, ch_c_cntxt_1_length_encode() previously hid the difference in bit width in the channel ring length field. Instead, define a new field CH_R_LENGTH and encode the ring size with reg_encode(). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-15net: ipa: define GSI CH_C_QOS register fieldsAlex Elder7-26/+72
Define the fields within the CH_C_QOS GSI register using an array of field masks in that register's reg structure. Use the reg functions for encoding values in those fields. One field in the register is present for IPA v4.0-4.2 only, two others are present starting at IPA v4.5, and one more is there starting at IPA v4.9. Drop the "GSI_" prefix in symbols defined in the gsi_prefetch_mode enumerated type, and define their values using decimal rather than hexidecimal values.

2023-02-15net: ipa: populate more GSI register filesAlex Elder6-2/+623
Create "gsi_v4.0.c", "gsi_v4.5.c", and "gsi_v4.9.c" as essentially identical copies of "gsi_v3.5.1.c". The only difference is the name of the exported "gsi_regs_vX_Y" structure. The next patch will start differentiating them. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
