2025-04-11wifi: ath12k: fix cleanup path after mhi initRaj Kumar Bhagat
Currently, the 'err_pci_msi_free' label is misplaced, causing the cleanup sequence to be incorrect. Fix this by moving the 'err_pci_msi_free' label to the correct position after 'err_irq_affinity_cleanup'.

2025-04-11wifi: ath12k: replace the usage of rx desc with rx_infoP Praneesh
In ath12k_dp_rx_h_mpdu(), during the undecap to native wifi mode, the rx descriptor memory is overwritten. After this function call, any subsequent accesses to rx descriptor related memory yield invalid values. Fix this by replacing instances where rx_desc was used with the pre-cached information in rx_info. This ensures that the values populated from the rx descriptor are accurate and prevents invalid memory access.

2025-04-07wifi: ath12k: Fix invalid memory access while forming 802.11 headerP Praneesh
While forming the 802.11 header from the rx descriptor, skb_push() is performed for the 802.11 header length and then calls ath12k_dp_rx_desc_get_dot11_hdr(). Since skb_push() moves the skb->data pointer backwards by the 802.11 header length, the rx descriptor points to a different memory area than intended, causing invalid information to be fetched from the rx descriptor. Also, when IV and ICV are not stripped from the given MSDU, mac80211 performs PN validation for these MSDUs, which requires the crypto header. Before forming the crypto header from the given rx descriptor, skb_push() is performed for the crypto header length, which overwrites the memory pointed to by the rx descriptor, causing invalid information to form the 802.11 header. Fix these issues by moving all rx descriptor accesses before the skb_push() operation which ensures the proper 802.11 headers are generated from the given rx descriptor and removing ath12k_dp_rxdesc_get_mpdu_frame_ctrl() for filling frame control, as this information is already fetched by ath12k_dp_rx_desc_get_dot11_hdr().

2025-04-07wifi: ath12k: Fix memory corruption during MLO multicast txP Praneesh
The struct sk_buff's control buffer is shared by mac80211's struct ieee80211_tx_info and ath12k's struct ath12k_skb_cb. When the driver wants to transmit an skb, it caches all the mac80211-specific information from struct ieee80211_tx_info, then performs a memset on the control buffer before writing the ath12k-specific information using struct ath12k_skb_cb. However, during multicast tx, the key is being filled into the driver data, which overwrites some crucial members like link_id and flags in struct ath12k_skb_cb. This causes invalid information retrieval when the driver accesses these fields during ath12k_dp_tx(). Fix this issue by removing the key filling logic during MLO multicast tx, as it is not used anywhere in the tx path.

2025-04-07wifi: ath12k: Fix memory leak during vdev_id mismatchP Praneesh
Currently driver enables vdev_id check as part of the bank configuration in ath12k_dp_tx_get_vdev_bank_config(). This check ensures that the vdev_id configured in the bank register aligns with the vdev_id in the packet's address search table within the firmware. If there is a mismatch, the firmware forwards the packet with the HTT status HAL_WBM_REL_HTT_TX_COMP_STATUS_VDEVID_MISMATCH. Since driver does not handle this vdev_id mismatch HTT status, the corresponding buffers are not freed properly, causing a memory leak. Fix this issue by adding handling to free the buffers when a vdev_id mismatch HTT status is encountered.

2025-04-02wifi: ath11k: fix node corruption in ar->arvifs listStone Zhang
In current WLAN recovery code flow, ath11k_core_halt() only reinitializes the "arvifs" list head. This will cause the list node immediately following the list head to become an invalid list node. Because the prev of that node still points to the list head "arvifs", but the next of the list head "arvifs" no longer points to that list node. When a WLAN recovery occurs during the execution of a vif removal, and it happens before the spin_lock_bh(&ar->data_lock) in ath11k_mac_op_remove_interface(), list_del() will detect the previously mentioned situation, thereby triggering a kernel panic. The fix is to remove and reinitialize all vif list nodes from the list head "arvifs" during WLAN halt. The reinitialization is to make the list nodes valid, ensuring that the list_del() in ath11k_mac_op_remove_interface() can execute normally.

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.

This causes ath12k_mac_station_add() to be called multiple times, and rx_stats is allocated each time. As a result there is memory leaks. Prevent multiple allocations of rx_stats when ath12k_mac_station_add() is called repeatedly by checking if rx_stats is already allocated before allocating again.

2025-03-31wifi: ath11k: choose default PM policy for hibernationBaochen Qiang
Now WoWLAN mode is chosen for those machines listed in the quirk table. This works for suspend (S3) but breaks for hibernation (S4), because WoWLAN mode requires WLAN power to be sustained, which is not the case during hibernation. For hibernation, the default mode should be used. Register a PM notifier with which kernel can notify us of the actual PM operation: if system is going to suspend, the original PM policy is honored; while if it is hibernation, overwrite it with default policy. To summarize: for suspend (S3), WoWLAN mode is chosen for machines listed in the quirk table, non-WoWLAN mode for others; for hibernation (S4), non-WoWLAN mode is chosen for all.

2025-03-31wifi: ath11k: support non-WoWLAN mode suspend as wellBaochen Qiang
Previously commit 166a490f59ac ("wifi: ath11k: support hibernation") was reverted due to [1], so currently we only support WoWLAN mode suspend. This works well in scenarios where WLAN power is sustained during suspend, however breaks in those where power is cut off. This change basically brings the reverted commit back, but differs in that we decide based on the PM policy to choose WoWLAN mode suspend or the non-WoWLAN mode. As stated in the previous patch for now the PM policy is determined based on machine models. That said we will choose WoWLAN mode suspend if we are running on machines listed in ath11k_pm_quirk_table, otherwise we choose the other one.

Due to [1] we currently put WLAN target into WoWLAN mode regardless of machine models. In upcoming patches we will support another mode, and finally which mode is chosen depends on the exact machine model. To prepare for such change, refactor the actual WoWLAN stuff in ath11k_core_suspend() into a new helper ath11k_core_suspend_wow(), this increase the code readability when the new suspend mode is added in upcoming patches. Same change applies to ath11k_core_resume(); [1] https://bugzilla.kernel.org/show_bug.cgi?id=219196 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30 Tested-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Tested-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Baochen Qiang <quic_bqiang@quicinc.com> Link: https://patch.msgid.link/20250328-ath11k-bring-hibernation-back-v3-3-23405ae23431@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>

2025-03-31wifi: ath11k: determine PM policy based on machine modelBaochen Qiang
To handle the Lenovo unexpected wakeup issue [1], previously we revert commit 166a490f59ac ("wifi: ath11k: support hibernation"). So currently WLAN target is put into WoWLAN mode during suspend. This is a temporary solution as it does not work on machines where WLAN power is cut off. The thought here is that we do WoWLAN suspend on Lenovo machines while do non-WoWLAN suspend (which is done in the reverted commit) on other machines. This requires us to identify Lenovo machines from others. For that purpose, read board vendor and product name from DMI interface, match it against all known affected machines. If there is a match, choose WoWLAN suspend mode, else choose non-WoWLAN mode. Save the mode in ab for later reference.

2025-03-27wifi: ath12k: extend dma mask to 36 bitsJohan Hovold
Extend the DMA mask to 36 bits to avoid using bounce buffers on machines without an iommu (under OS control) similar to what was done for ath11k in commit dbd73acb22d8 ("wifi: ath11k: enable 36 bit mask for stream DMA"). This specifically avoids using bounce buffers on Qualcomm Snapdragon X Elite machines like the Lenovo ThinkPad T14s when running at EL1. Note that the mask could possibly be extended further but unresolved DMA issues with 64 GiB X Elite machines currently prevents that from being tested. Also note that the driver is limited to 32 bits for coherent allocations and that there is no need to check for errors when setting masks larger than 32 bits.

2025-03-25wifi: ath12k: add support for fixed QMI firmware memoryRaj Kumar Bhagat
IPQ5332 firmware supports only fixed QMI firmware memory. Hence, add support to read reserved fixed memory region from device-tree and provide the reserved memory segments for firmware to use during QMI firmware memory request. Note that the ability to set the fixed memory will be introduced in a subsequent patch. Currently, the flag remains unset by default, ensuring that existing chipsets are unaffected.

2025-03-25wifi: ath12k: Add hw_params to remap CE register space for IPQ5332Balamurugan S
For IPQ5332 CE register space is moved out of WCSS region and the space is not contiguous. Hence, add hardware params (ce_ie_addr & ce_remap) for IPQ5332. These parameters would be used by Ath12k AHB driver (in subsequent patches) to remap the CE registers to a new space for accessing them.

2025-03-25wifi: ath12k: avoid m3 firmware download in AHB device IPQ5332Balamurugan S
Current ath12k devices, QCN9274 and WCN7850, supports m3.bin firmware download through ath12k driver. The new ath12k AHB based device IPQ5332 supports m3 firmware download through remoteproc driver. Hence, add new parameter (fw.m3_loader) in ath12k_hw_params to avoid m3 firmware download in IPQ5332.

2025-03-25wifi: ath12k: fix incorrect CE addressesBalamurugan S
In the current ath12k implementation, the CE addresses CE_HOST_IE_ADDRESS and CE_HOST_IE_2_ADDRESS are incorrect. These values were inherited from ath11k, but ath12k does not currently use them. However, the Ath12k AHB support relies on these addresses. Therefore, correct the CE addresses for ath12k.
