2025-06-10octeontx2-pf: Avoid typecasts by simplifying otx2_atomic64_add macroSubbaraya Sundeep
Just because otx2_atomic64_add is using u64 pointer as argument all callers has to typecast __iomem void pointers which inturn causing sparse warnings. Fix those by changing otx2_atomic64_add argument to void pointer.

2025-06-10netconsole: Add automatic console unregistration on target removalBreno Leitao
Add unregister_netcons_consoles() function to automatically unregister console handlers when no targets of the corresponding type remain active. The function iterates through the target list to determine which console types (basic vs extended) are still needed, and unregisters any console handlers that are no longer required. This prevents having registered console handlers without corresponding active targets. The function is called when a target is disabled and moved to the cleanup list, ensuring proper cleanup of unused console registrations.

2025-06-10netconsole: Only register console drivers when targets are configuredBreno Leitao
The netconsole driver currently registers the basic console driver unconditionally during initialization, even when only extended targets are configured. This results in unnecessary console registration and performance overhead, as the write_msg() callback is invoked for every log message only to return early when no matching targets are found. Optimize the driver by conditionally registering console drivers based on the actual target configuration. The basic console driver is now registered only when non-extended targets exist, same as the extended console. The implementation also handles dynamic target creation through the configfs interface. This change eliminates unnecessary console driver registrations, redundant write_msg() callbacks for unused console types, and associated lock contention and target list iterations. The optimization is particularly beneficial for systems using only the most common extended console type.

2025-06-10e1000: Move cancel_work_sync to avoid deadlockJoe Damato
Previously, e1000_down called cancel_work_sync for the e1000 reset task (via e1000_down_and_stop), which takes RTNL. As reported by users and syzbot, a deadlock is possible in the following scenario: CPU 0: - RTNL is held - e1000_close - e1000_down - cancel_work_sync (cancel / wait for e1000_reset_task()) CPU 1: - process_one_work - e1000_reset_task - take RTNL To remedy this, avoid calling cancel_work_sync from e1000_down (e1000_reset_task does nothing if the device is down anyway). Instead, call cancel_work_sync for e1000_reset_task when the device is being removed.

2025-06-09ice: add a separate Rx handler for flow director commandsMichal Kubiak
The "ice" driver implementation uses the control VSI to handle the flow director configuration for PFs and VFs. Unfortunately, although a separate VSI type was created to handle flow director queues, the Rx queue handler was shared between the flow director and a standard NAPI Rx handler. Such a design approach was not very flexible. First, it mixed hotpath and slowpath code, blocking their further optimization. It also created a huge overkill for the flow director command processing, which is descriptor-based only, so there is no need to allocate Rx data buffers. For the above reasons, implement a separate Rx handler for the control VSI. Also, remove from the NAPI handler the code dedicated to configuring the flow director rules on VFs. Do not allocate Rx data buffers to the flow director queues because their processing is descriptor-based only. Finally, allow Rx data queues to be allocated only for VSIs that have netdev assigned to them. This handler splitting approach is the first step in converting the driver to use the Page Pool (which can only be used for data queues). Test hints: 1. Create a VF for any PF managed by the ice driver. 2. In a loop, add and delete flow director rules for the VF, e.g.: for i in {1..128}; do q=$(( i % 16 )) ethtool -N ens802f0v0 flow-type tcp4 dst-port "$i" action "$q" done for i in {0..127}; do ethtool -N ens802f0v0 delete "$i" done Suggested-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> Suggested-by: Michal Swiatkowski <michal.swiatkowski@intel.com> Acked-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Michal Kubiak <michal.kubiak@intel.com> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2025-06-09ice: redesign dpll sma/u.fl pins controlArkadiusz Kubalewski
DPLL-enabled E810 NIC driver provides user with list of input and output pins. Hardware internal design impacts user control over SMA and U.FL pins. Currently end-user view on those dpll pins doesn't provide any layer of abstraction. On the hardware level SMA and U.FL pins are tied together due to existence of direction control logic for each pair: - SMA1 (bi-directional) and U.FL1 (only output) - SMA2 (bi-directional) and U.FL2 (only input) The user activity on each pin of the pair may impact the state of the other. Previously all the pins were provided to the user as is, without the control over SMA pins direction. Introduce a software controlled layer of abstraction over external board pins, instead of providing the user with access to raw pins connected to the dpll: - new software controlled SMA and U.FL pins, - callback operations directing user requests to corresponding hardware pins according to the runtime configuration, - ability to control SMA pins direction.

The virtchnl.h header makes no mention of where the bit definitions reside. Maintaining a separate copy of these bits across three drivers is cumbersome. Move the definition to libie as a new pctype.h header file. Each driver can include this, and drop its own definition. The ice implementation also defined a ICE_AVF_FLOW_FIELD_INVALID, intending to use this to indicate when there were no hash enable bits set. This is confusing, since the enumeration is using bit positions. A value of 0 *should* indicate the first bit. Instead, rewrite the code that uses ICE_AVF_FLOW_FIELD_INVALID to just check if the avf_hash is zero. From context this should be clear that we're checking if none of the bits are set. The values are kept as bit positions instead of encoding the BIT_ULL directly into their value. While most users will simply use BIT_ULL immediately, i40e uses the macros both with BIT_ULL and test_bit/set_bit calls.

2025-06-09net: intel: rename 'hena' to 'hashcfg' for clarityJacob Keller
i40e, ice, and iAVF all use 'hena' as a shorthand for the "hash enable" configuration. This comes originally from the X710 datasheet 'xxQF_HENA' registers. In the context of the registers the meaning is fairly clear. However, on its own, hena is a weird name that can be more difficult to understand. This is especially true in ice. The E810 hardware doesn't even have registers with HENA in the name. Replace the shorthand 'hena' with 'hashcfg'. This makes it clear the variables deal with the Hash configuration, not just a single boolean on/off for all hashing. Do not update the register names. These come directly from the datasheet for X710 and X722, and it is more important that the names can be searched.

2025-06-07wifi: ath11k: consistently use ath11k_mac_get_fw_stats()Baochen Qiang
Currently to get firmware stats, ath11k_mac_op_get_txpower() calls ath11k_fw_stats_request() and ath11k_mac_op_sta_statistics() calls ath11k_mac_get_fw_stats(). Those two helpers are basically doing the same, except for: 1. ath11k_mac_get_fw_stats() verifies ar->state inside itself. 2. ath11k_mac_get_fw_stats() calls ath11k_mac_fw_stats_request() which then calls ath11k_mac_fw_stats_reset() to free pdev/vdev stats whereas only pdev stats are freed by ath11k_fw_stats_request(). 3. ath11k_mac_get_fw_stats() waits for ar->fw_stats_complete and ar->fw_stats_done, whereas ath11k_fw_stats_request() only waits for ar->fw_stats_complete. Change to call ath11k_mac_get_fw_stats() in ath11k_mac_op_get_txpower(). This is valid because: 1. ath11k_mac_op_get_txpower() also has the same request on ar->state. 2. it is harmless to call ath11k_fw_stats_vdevs_free() since ar->fw_stats.vdevs should be empty and there should be no one expecting it at that time. 3. ath11k_mac_op_get_txpower() only needs pdev stats. For pdev stats, ar->fw_stats_done is set to true whenever ar->fw_stats_complete is set to true in ath11k_update_stats_event(). So additional wait on ar->fw_stats_done does not wast any time.

In case there is no vdev started, this results in that below condition would never get satisfied ((++ar->fw_stats.num_vdev_recvd) == total_vdevs_started) finally the requestor would be blocked until wait time out.
