git://git.kernel.org/pub/scm/linux/kernel/git/ath/ath ath.git patch for v6.14-rc Fix an issue in the ath12k driver where 6 GHz operation no longer works with new firmware.
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.

2025-01-07wifi: ath12k: set flag for mgmt no-ack frames in Tx completionRamya Gnanasekar
IEEE80211_TX_STAT_NOACK_TRANSMITTED flag signifies that frame was successfully transmitted without any errors when no-ack is requested. In WMI Tx management completion path, driver is not setting IEEE80211_TX_STAT_NOACK_TRANSMITTED flag for the frames with IEEE80211_TX_CTL_NO_ACK. Without this flag, the management frame statistics will not track such frames. Add IEEE80211_TX_STAT_NOACK_TRANSMITTED flag as part of the flags in skb transmit information when WMI is processing Tx completion for management frames.

2025-01-07wifi: ath12k: handle radar detection with MLOAditya Kumar Singh
ieee80211_radar_detected() expects the driver to pass a channel context configuration during MLO. This is used to identify exactly which link detected the radar. Add support to pass this to mac80211. Since the link arvif is not known in the WMI event, introduce a helper iterator API, ath12k_mac_get_any_chanctx_conf_iter(), to get the channel context configuration.

2024-12-16wifi: ath12k: add no-op without debug print in WMI Rx eventAditya Kumar Singh
Currently, certain WMI events are frequently received by the host. Since the host lacks the logic to process these events, the console is flooded with ‘Unknown eventid:’ debug messages. 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.

2024-12-16wifi: ath12k: symmetrize scan vdev creation and deletion during HW scanAditya Kumar Singh
Currently, the hardware scan is initiated in the driver on scan link (15). After mapping to the appropriate radio based on the scan frequency, the vdev is created and the scan begins. However, the vdev is only deleted when channel assignment is about to occur after the scan. Additionally, it is also deleted if a new scan is requested on the same interface but the underlying radio differs in the new request. This imbalance leads to various hardware scan issues, especially when a non-MLO and MLO combination exists. In such cases, the latter tries to skip the scan and proceed with channel assignment while the former is still scanning, causing a firmware assert. To address this issue, symmetrize the scan vdev creation and deletion during hardware scan operations. This means creating a vdev when the scan starts and deleting it once the scan is completed or aborted. While at this, add a few debug prints in scan handling and a few empty lines for better code read.

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.

2024-09-06wifi: mac80211: handle ieee80211_radar_detected() for MLOAditya Kumar Singh
Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.

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

Currently, ath12k_wmi_pdev_dma_ring_cfg() fails due to an invalid pdev_id parameter passed to the WMI_PDEV_DMA_RING_CFG_REQ_CMDID WMI command. This invalid pdev_id is caused by a double conversion of the MAC ID. Since the the caller of ath12k_wmi_pdev_dma_ring_cfg() already performs the MAC ID conversion, it is unnecessary to do it again within the function. To fix this, remove the software (SW) to hardware (HW) MAC ID conversion from ath12k_wmi_pdev_dma_ring_cfg() to avoid this redundant conversion. Found in code review.

When AP goes down or too far away without indication to STA, beacon miss will be detected. Then for WCN7850's firmware, it will use roam event to send beacon miss to host. If STA doesn't handle the beacon miss, will keep the fake connection and unable to roam. So add support for WCN7850 to trigger disconnection from AP when receiving this event from firmware. It has to be noted that beacon miss event notification for QCN9274 to be handled in a separate patch as it uses STA kickout WMI event to notify beacon miss and the current STA kickout event is processed as low_ack.
