2024-06-26wifi: ath12k: fix peer metadata parsingKarthikeyan Periyasamy
Currently, the Rx data path only supports parsing peer metadata of version zero. However, the QCN9274 platform configures the peer metadata version as V1B. When V1B peer metadata is parsed using the version zero logic, invalid data is populated, causing valid packets to be dropped. To address this issue, refactor the peer metadata version and add the version based parsing to populate the data from peer metadata correctly.

2024-06-24wifi: ath12k: handle keepalive during WoWLAN suspend and resumeBaochen Qiang
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: 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

- A single beacon template is used for one multiple BSSID group as only one interface from group transmits the beacons. But firmware requires the host to send this template each time a nontransmitted interface is brought up. Hence, modify existing logic to retrieve the template from vif context of the transmitting interface. Also, firmware crashes if host sends a template for a nontransmitted interface which is already up, add a check to avoid this. - Set rsnie_present and wpaie_present fields for nontransmitted VAPs. - Send offset to the multiple BSSID element in the beacon template firmware.

2024-05-13wifi: ath12k: avoid double SW2HW_MACID conversionKarthikeyan Periyasamy
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.

2024-04-24wifi: ath12k: add support to handle beacon miss for WCN7850Kang Yang
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.

For P2P mode, the WLAN interface may be requested to remain on a specific channel and then to send some management frames on that channel. Now chananel frequency of wmi_mgmt_send_cmd is set as 0. As a result, firmware may choose a default but wrong channel. Fix it by assigning chanfreq field with the ROC channel frequency. This change only applies to WCN7850, other chips are not affected.

2024-02-02wifi: ath12k: fix firmware assert during insmod in memory segment modeAaradhana Sahu
In segment memory mode, firmware allocates memory segments of size 2 MB. This 2 MB memory is used by firmware for the number of peers. This number of peer is sent from host to firmware during WMI init command. For single-phy the number of peers sent is TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) = 1058. With this 1058 number of peers firmware is unable to allocate memory in 2 MB segment and firmware crash is observed. Hence, fix this firmware crash by reducing the number of stations TARGET_NUM_STATIONS for split-phy.
