2025-06-17wifi: ath12k: update freq range for each hardware modeBaochen Qiang
Previous patches parse and save hardware MAC frequency range information in ath12k_svc_ext_info structure. Such range represents hardware capability hence needs to be updated based on host information, e.g. guard the range based on host's low/high boundary. So update frequency range. The updated range is saved in ath12k_hw_mode_info structure and would be used when doing vdev activation and link selection in following patches.

6 GHz When station is connected to a 6 GHz AP, there are 2 ways to configure the power limit to firmware. The first way is to send 2 WMI commands WMI_PDEV_PARAM_TXPOWER_LIMIT2G/WMI_PDEV_PARAM_TXPOWER_LIMIT5G to firmware, the second way is to send WMI_VDEV_SET_TPC_POWER_CMDID to firmware which includes more parameters for power control. When firmware advertises WMI_TLV_SERVICE_EXT_TPC_REG_SUPPORT, it supports WMI_VDEV_SET_TPC_POWER_CMDID, ath12k uses it to send more parameters to firmware. As chanctx is needed to extract necessary info for this command, save it beforehand in ath12k_mac_op_assign_vif_chanctx().

2025-05-16wifi: ath12k: update regulatory rules when interface addedBaochen Qiang
There are two power types for 6 GHz regulatory, one is AP, another is client. The client power type is used for station interface, and AP power type is used for AP/mesh point interface. When firmware boots up, WMI_REG_CHAN_LIST_CC_EXT_EVENTID is sent from firmware at an early stage, the interface mode is not decided at this point, then ath12k select reg rules of AP type as default. After interface created, ath12k needs to update reg rules to the exact power type matching the interface type.

2025-05-16wifi: ath12k: add support to select 6 GHz regulatory typeBaochen Qiang
For 6 GHz band, firmware offers 3 types of regulatory rules for AP mode and 6 for station mode in WMI_REG_CHAN_LIST_CC_EXT_EVENTID event. In ath12k_reg_build_regd() current code by default chooses WMI_REG_INDOOR_AP type rules from AP mode reg list to build regdomain, regardless of the interface mode and power type, hence is not correct. Pass interface mode (wmi_vdev_type) and AP power type (ieee80211_ap_reg_power) as new arguments to ath12k_reg_build_regd() such that we can choose correct rules based on them. Currently ath12k_reg_build_regd() is called only by ath12k_reg_chan_list_event() when driver boots, at that time these two arguments are not determined yet, hence by default pass WMI_VDEV_TYPE_UNSPEC and IEEE80211_REG_UNSET_AP, this results in WMI_REG_INDOOR_AP being chosen at last. In upcoming patches the rules would be updated when these two arguments could be determined.

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.

2025-01-24wifi: ath12k: fix handling of 6 GHz rulesAditya Kumar Singh
In the US country code, to avoid including 6 GHz rules in the 5 GHz rules list, the number of 5 GHz rules is set to a default constant value of 4 (REG_US_5G_NUM_REG_RULES). However, if there are more than 4 valid 5 GHz rules, the current logic will bypass the legitimate 6 GHz rules. For example, if there are 5 valid 5 GHz rules and 1 valid 6 GHz rule, the current logic will only consider 4 of the 5 GHz rules, treating the last valid rule as a 6 GHz rule. Consequently, the actual 6 GHz rule is never processed, leading to the eventual disabling of 6 GHz channels. To fix this issue, instead of hardcoding the value to 4, use a helper function to determine the number of 6 GHz rules present in the 5 GHz rules list and ignore only those rules.

To address this, handle these events gracefully without printing debug messages. There is already a block of event IDs that are ignored with a debug print. However, this new type of event occurs more frequently, so no debug print is necessary, and handling it should be a no-op. While at it, re-arrange the code so that all Unknown event IDs are towards the end of the switch block.

2024-10-16wifi: ath12k: prepare vif data structure for MLO handlingSriram R
To prepare the driver for MLO support, split the driver vif data structure to scale for multiple links. This requires changing the use of arvif to per link and not per hw which can now comprise of multiple links. Also since most configurations from mac80211 are done per link, do refactoring of the driver functions to apply these configurations at link level. Split ath12k_vif which is the driver private of ieee80211_vif to store link specific information as ath12k_link_vif. For default use cases the ath12k vif will have a preallocated link vif called deflink which will be used by non ML and the first link vif of ML vif. With MLO support to be added, remaining link vifs will be allocated during channel assignment where vdev create/start happens. These link vifs will be freed during interface down. Current ath12k_vif(arvif) structure +---------------+ +---------------+ +---------------+ | ieee80211_vif | | ieee80211_vif | | ieee80211_vif | | private data | | private data | | private data | | | | | | | | ath12k_vif | | ath12k_vif | | ath12k_vif | | (arvif) | | (arvif) | | (arvif) | | | | | | | | +----------+ | | +----------+ | | +----------+ | | |*ar (2GHz)| | | |*ar (5GHz)| | | |*ar (2GHz)| | | +----------+ | | +----------+ | | +----------+ | | | | | | | +---------------+ +---------------+ +---------------+ The new ath12k_vif (ahvif) containing ath12k_link_vif(s) (arvif) (deflink is preallocated member which is always the first link if ieee80211_vif is MLD and is the only link otherwise): +---------------------------------+ | ieee80211_vif | | private data | | | | ath12k_vif(ahvif) | | | | +-------------------------------+ | |ath12k_link_vif deflink (arvif)| | | +---------------+ | | | | *ar(2GHz) | | | +-------------------------------+ | +-------------------------------+ | | ath12k_link_vif *link (arvif)| | | +---------------+ | | | | *ar(5GHz) | | | +-------------------------------+ | +-------------------------------+ | | ath12k_link_vif *link (arvif)| | | +---------------+ | | | | *ar(6GHz) | | | +-------------------------------+ | | +---------------------------------+ To refactor existing ath12k_vif to make use of link vifs, following changes are made: 1. ath12k_vif now called by variable name ahvif storing multiple arvifs (struct ah12k_link_vif) and also has a back pointer to ieee80211_vif. 2. In this patch set, only deflink is used to be on par with the existing code. When MLO support is added the link id will be used to fetch the arvif. 3. For mac80211 ops which doesn't use specific link_id, the config or info is common for the vif, hence apply the config to all link vifs. The links_map in the ahvif, will be used to identify all the link vifs that are setup. 4. Change ath12k_vif_to_arvif() as ath12k_vif_to_ahvif() to fetch the hw level vif. The link vif can be fetched from ahvif->link[], or the deflink can be accessed via ahvif->deflink. API to access link vif (arvif) by passing link_id can be introduced with MLO Support. 5. The ieee80211_vif can be accessed from ahvif using ath12k_ahvif_to_vif(). The locking continues to use wiphy_lock() for protecting access to most data in struct ath12k&co, there are no changes in that regard. Though struct ath12k_vif::link[] is protected with RCU.

With WoWLAN enabled and after sleeping for a rather long time, we are seeing that with some APs, it is not able to wake up the STA though the correct wake up pattern has been configured. This is because the host doesn't send keepalive command to firmware, thus firmware will not send any packet to the AP and after a specific time the AP kicks out the STA. So enable keepalive before going to suspend and disable it after resume back.

2024-06-24wifi: ath12k: implement hardware data filterBaochen Qiang
Host needs to set hardware data filter before entering WoW to let firmware drop needless broadcast/multicast frames to avoid frequent wakeup. Host clears hardware data filter when leaving WoW.

2024-06-24wifi: ath12k: add WoW net-detect functionalityBaochen Qiang
Implement net-detect feature by setting flag WIPHY_WOWLAN_NET_DETECT if firmware supports this feature. Driver sets the related PNO configuration to firmware before entering WoW and firmware then scans periodically and wakes up host if a specific SSID is found. Note that firmware crashes if we enable it for both P2P vdev and station vdev simultaneously because firmware can only support one vdev at a time. Since there is rare scenario for a P2P vdev to do net-detect, skip it for P2P vdevs. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 Signed-off-by: Baochen Qiang <quic_bqiang@quicinc.com> Acked-by: Jeff Johnson <quic_jjohnson@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://patch.msgid.link/20240604055407.12506-5-quic_bqiang@quicinc.com

Implement basic WoW functionalities such as magic-packet, disconnect and pattern. The logic is very similar to ath11k. When WoW is configured, ath12k_core_suspend and ath12k_core_resume are skipped (by checking ar->state) as we are not allowed to power cycle firmware.

2024-05-16wifi: ath12k: use correct MAX_RADIOSKarthikeyan Periyasamy
The current value of the MAX_RADIOS definition is 3. This is incorrect because no device supports more than 2 radios. An incorrect MAX_RADIOS value can lead to: - unnecessary memory allocation for pdev related entities. - invalid pdev id validation. - Misconceptions for code readers. Therefore, modify the MAX_RADIOS definition as 2.

Host needs to send multiple BSSID configurations to firmware for each vdev in ath12k_wmi_vdev_up() for AP mode. This function accepts individual input parameters hence any new argument will require changes to all callers. Most of these will use default value (0 or NULL).
