2025-06-17wifi: ath12k: don't use static variables in ath12k_wmi_fw_stats_process()Baochen Qiang
Currently ath12k_wmi_fw_stats_process() is using static variables to count firmware stat events. Taking num_vdev as an example, if for whatever reason (say ar->num_started_vdevs is 0 or firmware bug etc.) the following condition (++num_vdev) == total_vdevs_started is not met, is_end is not set thus num_vdev won't be cleared. Next time when firmware stats is requested again, even if everything is working fine, failure is expected due to the condition above will never be satisfied. The same applies to num_bcn as well. Change to use non-static counters and reset them each time before firmware stats is requested.

2025-06-17wifi: ath12k: don't activate more links than firmware supportsBaochen Qiang
In case of ML connection, currently all useful links are activated at ASSOC stage: ieee80211_set_active_links(vif, ieee80211_vif_usable_links(vif)) this results in firmware crash when the number of links activated on the same device is more than supported. Since firmware supports activating at most 2 links for a ML connection, to avoid firmware crash, host needs to select 2 links out of the useful links. As the assoc link has already been chosen, the question becomes how to determine partner links. A straightforward principle applied here is that the resulted combination should achieve the best throughput. For that purpose, ideally various factors like bandwidth, RSSI etc should be considered. But that would be too complicate. To make it easy, the choice is to only take hardware modes into consideration. The SBS (single band simultaneously) mode frequency range covers 5 GHz and 6 GHz bands. In this mode, the two individual MACs are both active, with one working on 5g-high band and the other on 5g-low band (from hardware perspective 5 GHz and 6 GHz bands are referred to as a 'large' single 5 GHz band). The DBS (dual band simultaneously) mode covers 2 GHz band and the 'large' 5 GHz band, with one MAC working on 2 GHz band and the other working on 5 GHz band or 6 GHz band. Since 5,6 GHz bands could provide higher bandwidth than 2 GHz band, the preference is given to SBS mode. Other hardware modes results in only one working MAC at any given time, so it is chosen only when both SBS are DBS are not possible. For each hardware mode, if there are more than one partner candidate, just choose the first one. For now only single device MLO case is handled as it is easy. Other cases could be addressed in the future.

2025-05-19wifi: ath12k: support usercase-specific firmware overridesMiaoqing Pan
Introduce 'firmware-name' property to allow end-users and/or integrators to decide which usecase-specific firmware to run on the WCN7850 platform. This is necessary due to resource limitations such as memory capacity and CPU capability, or performance and power optimization for different application scenarios. Currently, there are two firmwares, both files can be executed interchangeably. For example: - ath12k/WCN7850/hw2.0/amss.bin, ath12k/WCN7850/hw2.0/m3.bin ath12k/WCN7850/hw2.0/board-2.bin - ath12k/WCN7850/hw2.0/ncm825/amss.bin, ath12k/WCN7850/hw2.0/ncm825/m3.bin ath12k/WCN7850/hw2.0/board-2.bin The former is the default firmware, suitable for most WiFi 7 STA functions. The latter adds support for commercial-quality SAP and optimizes power consumption for IoT applications. And both use the same BDF/regdb data within the main board-2.bin.

2025-05-19wifi: ath12k: Reorder and relocate the release of resources in ↵Yingying Tang
ath12k_core_deinit() Ath12k panic notifier is registered in driver loading process. But it is not unregistered if ATH12K_FLAG_QMI_FAIL is set(e.g. load BDF failed) and unload driver. It causes a dirty node in panic notifier list since ath12k panic notifier is not unregistered from list but the buffer of this node is freed in driver unloading process. If load driver again there will be a page fault error due to this dirty node in panic notifier list. This issue is caused by asymmetry between ath12k_core_init() and ath12k_core_deinit(). Reorder and relocate the release of resources in ath12k_core_deinit() to avoid this asymmetry issue.

Currently we only build regdomain when channel list event is received. That event is received when driver boots or when a new country code is sent to firmware. At either time we may have no information about interface mode or AP's power type, consequently WMI_REG_INDOOR_AP is selected. In upcoming patches we will rebuild regdomain once those information is available. For that purpose reg info has to be stored/refreshed each time a new channel list event is received.

2025-04-17wifi: ath12k: Fix frequency range in driverAditya Kumar Singh
During the initial WMI exchange, the firmware updates the hardware-supported start and end frequencies in the ath12k_wmi_hal_reg_capabilities_ext_arg structure. These frequencies, being hardware-supported, may not always align with the current regulatory operating frequencies. When operating as multiple grouped hardwares under a single wiphy, the driver advertises these values directly to the upper layer in the per-radio frequency range, which can be misleading. Sample output snippet from iw phyX info command - [..] Supported wiphy radios: * Idx 0: Frequency Range: 2312 MHz - 2732 MHz [..] * Idx 1: Frequency Range: 5150 MHz - 5330 MHz [..] [..] The frequency range displayed above is incorrect because the driver directly advertises the hardware-supported values to the upper layer. The driver is aware of the current operating regulatory rules, and hence it can use this information to determine the final operating start and end frequencies. To resolve this issue, add support to store the start and end frequencies received during the regulatory update event. Then, intersect these with the hardware-supported start and end frequencies, and finally, advertise the intersected values to the upper layer. Sample output snippet from iw phyX info command after the fix - [..] Supported wiphy radios: * Idx 0: Frequency Range: 2402 MHz - 2472 MHz [..] * Idx 1: Frequency Range: 5170 MHz - 5330 MHz [..] [..] Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Aditya Kumar Singh <aditya.kumar.singh@oss.qualcomm.com> Co-developed-by: Rajat Soni <quic_rajson@quicinc.com> Signed-off-by: Rajat Soni <quic_rajson@quicinc.com> Reviewed-by: Vasanthakumar Thiagarajan <vasanthakumar.thiagarajan@oss.qualcomm.com> Link: https://patch.msgid.link/20250408042128.720263-3-quic_rajson@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
2025-04-15wifi: ath12k: alloc REO queue per stationBaochen Qiang
In MLO case, all link peers share the same REO queue, so the queue should be allocated only once, currently this is done by checking primary_link flag in ath12k_dp_rx_peer_tid_setup(). However, the check not only avoids duplicate allocation, but also bypasses sending queue configuration to firmware for non-primary links. In an upcoming patch, changes will be added to make this check no-ops for WCN7850, as WCN7850 firmware needs to be explicitly notified each link peer's queue configuration. That said, the duplicate allocation would arise again after that change, hence it needs to be resolved before hand. Since all link peers share the same queue, it should be allocated per MLD peer, not per link peer. So change to do allocation once and save it in MLD peer, link peers can simply get queue configuration from there. Also relocate ath12k_reoq_buf structure to core.h to avoid circular dependency.

2025-04-15wifi: ath12k: identify assoc link vif in station modeBaochen Qiang
In MLO scenario, for station mode interface, WCN7850 firmware requests the assoc link vdev to get started before any other link vdevs starts. Firmware internally checks assoc_link field of wmi_vdev_start_mlo_params.flags when the first vdev starts. And if the check fails firmware crashes. Current connection flow guarantees the assoc link vdev gets started first (at assoc stage only one link vdev is created/started, i.e. the assoc link vdev), however the assoc_link flag is never set, resulting in WCN7850 firmware crash. Note ath12k_link_sta structure already has is_assoc_link flag, and it is properly set for assoc link. However we can not use it because it won't be available before peer gets created, which is too late for vdev starts. So add a new flag 'is_sta_assoc_link' in ath12k_link_vif structure and set it when deflink vdev is created. This is valid because we always use deflink as the assoc link. This flag is passed to firmware vdev starts to avoid firmware crash. Also verify the link vif/sta pair has the same settings when creating link sta.

Currently fw_features is used to check if a specific feature is supported or not: if the feature bit is set the feature is believed to be supported, otherwise not supported. Since fw_features is populated only when using firmware API-2, and by default it is zero, in case of API-1 such as WCN7850 firmware it is possible that a feature is not enabled by host while actually firmware supports it. To avoid this, add a new flag indicating whether fw_features has been ever populated or not, and only when that flag is true we choose to believe fw_features.

2025-04-02wifi: ath12k: add 11d scan offload supportWen Gong
The flow of 11d scan is: 1. trigger 11d scan. 2. receive, parse, and update 11d scan result. 3. stop 11d scan. So need to add handler for WMI_11D_SCAN_START_CMDID and WMI_11D_SCAN_STOP_CMDID to trigger/stop 11d scan. Add process of WMI event WMI_11D_NEW_COUNTRY_EVENTID for 11d scan result. There are two points that need to be noted: 1. The 11d scan priority is 'MEDIUM' in firmware, the hw scan priority is 'LOW'. When 11d scan is running, hw scan will be canceled. To avoid this, change the hw scan priority to 'MEDIUM' when 11d scan is running. 2. Need to add wait_for_completion_timeout() for scan.complete in ath12k_reg_update_chan_list() because 11d scan will cost more than 5 seconds. Due to another existing wait in ath12k_scan_stop(), there will be two scan.complete in different threads. Therefore use complete_all() instead of complete() for scan.complete. complete_all() can work well when it is only one thread wait for scan.complete.

2025-03-17wifi: ath12k: add get_txpower mac opsAditya Kumar Singh
Driver does not support get_txpower mac ops because of which cfg80211 returns vif->bss_conf.txpower to user space. bss_conf.txpower gets its value from ieee80211_channel->max_reg_power. However, the final txpower is dependent on few other parameters apart from max regulatory supported power. It is the firmware which knows about all these parameters and considers the minimum for each packet transmission. All ath12k firmware reports the final TX power in firmware pdev stats which falls under fw_stats. add get_txpower mac ops to get the TX power from firmware leveraging fw_stats and return it accordingly. While at it, there is a possibility that repeated stats request WMI commands are queued to FW if mac80211/userspace does get tx power back to back(in Multiple BSS cases). This could potentially consume the WMI queue completely. Hence limit this by fetching the power only for every 5 seconds and reusing the value until the refresh timeout or when there is a change in channel. Also remove init_completion(&ar->fw_stats_complete) in ath12k_mac_hw_register() as ath12k_fw_stats_init() takes care of it for each ar.

TPC config parameters along with regulatory power array comes as first event. Rates array comes as second and third event as it cannot be packed in single event. Conformance Test Limit (CTL) power array comes as the fourth event. Firmware packs different sets of array params which includes array length and type inside master TLV as different subtlvs. And the actual content of array is packed one after the other inside a separate TLV as single buffer. Parse various events and save it in local structures. Create tpc_stats file using debugfs to store these local structures.

As the napi will be only enabled after qmi_firmware_ready event, trying napi_synchronize() before napi_enable() will result in indefinite sleep in case of a firmware crash in QMI init sequence.

2025-02-03wifi: ath12k: prevent CSA counter to reach 0 and hit WARN_ON_ONCEAditya Kumar Singh
Currently, when the driver receives a channel switch count WMI event from the firmware with a count greater than 1, it calls ieee80211_beacon_update_cntdwn(). If the beacon transmission fails, the event will be received again with the previous count value. In this scenario, the host decrements the mac80211 counter again, causing it to move ahead of the firmware counter. Ultimately, when the firmware count reaches 1, the mac80211 counter will reach zero, triggering a WARN_ON_ONCE(). Therefore, there is a need to check the count value in the event. Hence to fix this, maintain the current ongoing counter in arvif. If the count in the event does not match the expected value, silently discard the event.

This causes driver to overwrite the existing PPDU information with the new PPDU information. Fix it by recording the end reason which is provided under each buffer's descriptor in skb->cb and uses it while parsing TLV tags to mark the PPDU end delimiter.
