2021-07-29dpaa2-switch: offload shared block mirror filters when binding to a portIoana Ciornei3-0/+71
When mirroring rules are added in shared filter blocks, the same mirroring rule has to be configured on all the switch ports that are part of the same block. In case a switch port joins a shared block after mirroring filters have been already added to it, then all the mirror rules should be offloaded to the port. The reverse, removal of mirroring rules, has to be done at block unbind. For this purpose, the dpaa2_switch_block_offload_mirror() and dpaa2_switch_block_unoffload_mirror() functions are added and called upon binding and unbinding a switch port to/from a block.

2021-07-29dpaa2-switch: add support for port mirroringIoana Ciornei3-5/+182
Add support for per port mirroring for the DPAA2 switch. We support only single mirror port, therefore we allow mirroring rules only as long as the destination port is always the same. Unlike all the actions (drop, redirect, trap) already supported by the dpaa2-switch driver, adding mirroring filters in shared blocks is not achieved by a singular ACL entry added in a table shared by the ports. This is why, when a new mirror filter is added in a block we have to got through all the switch ports sharing it and configure the filter individually on all.

Until now, shared filter blocks were implemented only by ACL tables shared between ports. Going forward, when the mirroring support will be added, this will not be true anymore. Rename the dpaa2_switch_acl_tbl into dpaa2_switch_filter_block so that we make it clear that the structure is used not only for filters that use the ACL table but will be used for all the filters that are added in a block.

1PPS (One Pulse Per Second) is a signal generated either by the NIC PHC or an external timing source. Integrating the support to configure and use 1PPS using the TSIO pins along with PTP timestamps will add Grand Master capability to the 5750X family chipsets. This patch initializes the driver data structures and registers the 1PPS with kernel, based on the TSIO pins' capability in the hardware. This will create a /dev/ppsX device which applications can use to receive PPS events. Later patches will define functions to configure and use the pins.

During error recovery or hot firmware upgrade, the chip may be under reset and the PHC register read cycles may cause completion timeouts. Check that the chip is not under reset condition before proceeding to read the PHC by checking the flag BNXT_STATE_IN_FW_RESET. We also need to take the ptp_lock before we set this flag to prevent race conditions. We need this logic because the PHC now will stay registered after bnxt_close().

Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

2021-07-27net: build all switchdev drivers as modules when the bridge is a moduleVladimir Oltean2-0/+3
Currently, all drivers depend on the bool CONFIG_NET_SWITCHDEV, but only the drivers that call some sort of function exported by the bridge, like br_vlan_enabled() or whatever, have an extra dependency on CONFIG_BRIDGE. Since the blamed commit, all switchdev drivers have a functional dependency upon switchdev_bridge_port_{,un}offload(), which is a pair of functions exported by the bridge module and not by the bridge-independent part of CONFIG_NET_SWITCHDEV. Problems appear when we have: CONFIG_BRIDGE=m CONFIG_NET_SWITCHDEV=y CONFIG_TI_CPSW_SWITCHDEV=y because cpsw, am65_cpsw and sparx5 will then be built-in but they will call a symbol exported by a loadable module. This is not possible and will result in the following build error: drivers/net/ethernet/ti/cpsw_new.o: in function `cpsw_netdevice_event': drivers/net/ethernet/ti/cpsw_new.c:1520: undefined reference to `switchdev_bridge_port_offload' drivers/net/ethernet/ti/cpsw_new.c:1537: undefined reference to `switchdev_bridge_port_unoffload' As mentioned, the other switchdev drivers don't suffer from this because switchdev_bridge_port_offload() is not the first symbol exported by the bridge that they are calling, so they already needed to deal with this in the same way.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2021-07-24 This series aims to reduce coupling in mlx5e, particularly between RX resources (TIRs, RQTs) and numerous code units that use them. This refactoring is required for upcoming features, ADQ and TX lag hashing. The issue with the current code is that TIRs and RQTs are unmanaged, different places all over the driver create, destroy, track and configure them, often in an uncoordinated way. The responsibilities of different units become vague, leading to a lot of hidden dependencies between numerous units and tight coupling between them, which is prone to bugs and hard to maintain. The result of this refactoring is: 1. Creating a manager for RX resources, that controls their lifecycle and provides a clear API, which restricts the set of actions that other units can do. 2. Using object-oriented approach for TIRs, RQTs and RX resource manager (struct mlx5e_rx_res). 3. Fixing a few bugs and misbehaviors found during the refactoring. 4. Reducing the amount of dependencies, removing hidden dependencies, making them one-directional and organizing the code in clear abstraction layers. 5. Explicitly exposing the remaining weird dependencies. 6. Simplifying and organizing code that creates and modifies TIRs and RQTs.

2021-07-26net/mlx5e: Remove lro_param from mlx5e_build_indir_tir_ctx_common()Maxim Mikityanskiy1-6/+6
In order to reduce the list of parameters and to define clearer responsibility for mlx5e_build_indir_tir_ctx_common(), stop passing lro_param and instead call mlx5e_build_tir_ctx_lro() directly where needed.

2021-07-26net/mlx5e: Remove mlx5e_priv usage from mlx5e_build_*tir_ctx*()Maxim Mikityanskiy3-36/+56
The functions that build TIR context for TIR create and modify commands used to depend on struct mlx5e_priv and fetch some values directly from different places. It increased coupling of code and the chance of weird misbehavior due to hidden complex dependencies. As the first step, this commit removes the priv parameter from these functions. Instead, the necessary values are passed directly.

2021-07-26net/mlx5e: Use mlx5e_rqt_get_rqtn to access RQT hardware idMaxim Mikityanskiy3-5/+9
In order to abstract from implementation details of mlx5e_rqt, use the mlx5e_rqt_get_rqtn getter instead of accessing the field directly. Signed-off-by: Maxim Mikityanskiy <maximmi@nvidia.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2021-07-26net/mlx5e: Take RQT out of TIR and group RX resourcesMaxim Mikityanskiy11-119/+188
RQT is not part of TIR, as multiple TIRs may point to the same RQT, as it happens with indir_tir and inner_indir_tir. These instances of a TIR don't use the embedded RQT. This commit takes RQT out of TIR, making them independent. The RQTs are placed into struct mlx5e_rx_res, and items in that struct are regrouped by functionality: RSS, channels and PTP.
