X-BeenThere: intel-wired-lan@osuosl.org X-Mailman-Version: 2.1.30 Precedence: list List-Id: Intel Wired Ethernet Linux Kernel Driver Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: intel-wired-lan-bounces@osuosl.org Sender: "Intel-wired-lan" This series extends Marvell octeontx2-af support for CN20K NPC (MCAM debuggability, allocation policy, default-rule lifetime, optional KPU profiles from firmware files, X2/X4 MCAM keyword handling in flows and defaults, and dynamic CN20K NPC private state), adds a devlink mechanism for multi-value parameters, and adjusts devlink param netlink helpers and mlx5 so stack usage stays within -Wframe-larger-than limits once union devlink_param_value grows. Patch 1 improves CN20K MCAM visibility in debugfs: mcam_layout marks enabled entries, dstats reports per-entry hit deltas, and mismatch lists enabled entries without a PF mapping. MCAM enable state is tracked in a bitmap updated from the CN20K enable path. Patch 2 reduces stack usage in mlx5e_pcie_cong_get_thresh_config() by reusing a single union devlink_param_value and a local result struct instead of holding a large array of unions on the stack, so the helper stays under the frame-size warning limit as the union grows (patches 3-4). Patch 3 changes devlink_nl_param_value_put() and devlink_nl_param_value_fill_one() to pass union devlink_param_value by pointer instead of by value. Passing two copies of the union by value in the param netlink path consumes over 500 bytes of argument stack and risks CONFIG_FRAME_WARN as the union grows beyond its historical size (patch 4). Patch 4 (Saeed) introduces DEVLINK_PARAM_TYPE_U64_ARRAY and nested DEVLINK_ATTR_PARAM_VALUE_DATA attributes so drivers and user space can exchange bounded u64 arrays; YAML, uapi, and netlink validation are updated. Patch 5 adds a runtime devlink parameter srch_order to reorder CN20K subbank search during MCAM allocation. Patch 6 ties default MCAM entries to NIX LF alloc/free on CN20K, adds NIX_LF_DONT_FREE_DFT_IDXS for PF teardown paths that must not drop default NPC indexes while the driver still owns state, and tightens nix_lf_alloc error propagation. Patch 7 allows loading a custom KPU profile from /lib/firmware/kpu via module parameter kpu_profile, with cam2 / ptype_mask wiring and helpers that share firmware-sourced vs filesystem-sourced profile layouts. Patch 8 makes default-rule allocation, AF flow install, and PF-side RSS, defaults, and ethtool flows respect the active CN20K MCAM keyword width (X2 vs X4), including X4 reference-index masking and -EOPNOTSUPP when a flow needs X4 keys on an X2-only profile. Patch 9 replaces file-scope npc_priv and static dstats with allocation sized from discovered bank/subbank geometry, threads npc_priv_get() through CN20K NPC paths, and allocates dstats via devm_kzalloc for the debugfs helper. The mlx5 change sits immediately before the devlink patches so the series applies cleanly and stays warning-free when built incrementally; pass-by-pointer precedes the U64 array type so helpers are not copying an even larger union by value. The CN20K patches keep srch_order ahead of NIX LF coordination, KPU-from-filesystem, X2/X4 handling, and the npc_priv refactor that touches the same files heavily.
