2025-05-16wifi: ath12k: update regulatory rules when connection establishedBaochen Qiang
Once connection to AP established we know the exact power type, it is time to update regulatory rules based on such info.

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: determine interface mode in _op_add_interface()Baochen Qiang
Currently interface mode is determined each time a vdev is created. In MLO scenario where there could be multiple vdevs this is just a waste of time. Move related logic into a new helper ath12k_mac_determine_vdev_type() and call it once in ath12k_mac_op_add_interface().

2025-05-16wifi: ath12k: store reg info for later useBaochen Qiang
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. The stored reg info would be freed in ath12k_reg_free() when it is not needed.

2025-05-16wifi: ath12k: move reg info handling outsideBaochen Qiang
The reg info is allocated in ath12k_reg_chan_list_event() but validated in ath12k_reg_handle_chan_list(). Currently this is good since reg info would be freed regardless of validation results. However in an upcoming patch the reg info might need to be stored for later use if the result is good. Since we can not tell the result from return value of ath12k_reg_handle_chan_list(), we need to move validation out of it. Add a new helper ath12k_reg_validate_reg_info() and call it in ath12k_reg_chan_list_event(), based on the result we can choose to store or free it in the following patch.

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.

2025-05-16wifi: ath12k: refactor ath12k_reg_build_regd()Baochen Qiang

Move related logic into ath12k_reg_build_regd() to make code clear. Also relocate ath12k_reg_is_world_alpha() to avoid forward declaration, and refine it for code simplicity.

2025-05-16wifi: ath12k: refactor ath12k_reg_chan_list_event()Baochen Qiang
ath12k_reg_chan_list_event() is doing quite some work: allocate/free reg_info, parse chan list event and store required info in reg_info, process reg_info, build regd and queue work item for later processing etc, which makes it hard to read. Refactor this function: 1. extract reg_info processing and regd building into a new helper ath12k_reg_handle_chan_list(). 2. extract reg_info free into a new helper ath12k_reg_reset_reg_info(). Note the refactor also benefit some upcoming patches where these helpers are getting called. Also relocate these two helpers and the existing ath12k_reg_is_world_alpha() to reg.c to reflect what they are doing. And update fw to firmware while relocating.

2025-05-16wifi: ath12k: fix a possible dead lock caused by ab->base_lockBaochen Qiang
spin_lock/spin_unlock are used in ath12k_reg_chan_list_event to acquire/release ab->base_lock. For now this is safe because that function is only called in soft IRQ context. But ath12k_reg_chan_list_event() will be called from process context in an upcoming patch, and this can result in a deadlock if ab->base_lock is acquired in process context and then soft IRQ occurs on the same CPU and tries to acquire that lock. Fix it by using spin_lock_bh and spin_unlock_bh instead.

Add the missing memory barrier to make sure that the REO dest ring descriptor is read after the head pointer to avoid using stale data on weakly ordered architectures like aarch64. This may fix the ring-buffer corruption worked around by commit f9fff67d2d7c ("wifi: ath11k: Fix SKB corruption in REO destination ring") by silently discarding data, and may possibly also address user reported errors like: ath11k_pci 0006:01:00.0: msdu_done bit in attention is not set Tested-on: WCN6855 hw2.1 WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.41 Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices") Cc: stable@vger.kernel.org # 5.6 Link: https://bugzilla.kernel.org/show_bug.cgi?id=218005 Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Tested-by: Clayton Craft <clayton@craftyguy.net> Link: https://patch.msgid.link/20250321145302.4775-1-johan+linaro@kernel.org Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
2025-05-16wifi: ath11k: fix ring-buffer corruptionJohan Hovold
Users of the Lenovo ThinkPad X13s have reported that Wi-Fi sometimes breaks and the log fills up with errors like: ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1484, expected 1492 ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1460, expected 1484 which based on a quick look at the driver seemed to indicate some kind of ring-buffer corruption. Miaoqing Pan tracked it down to the host seeing the updated destination ring head pointer before the updated descriptor, and the error handling for that in turn leaves the ring buffer in an inconsistent state. Add the missing memory barrier to make sure that the descriptor is read after the head pointer to address the root cause of the corruption while fixing up the error handling in case there are ever any (ordering) bugs on the device side. Note that the READ_ONCE() are only needed to avoid compiler mischief in case the ring-buffer helpers are ever inlined.

2025-05-16wifi: ath11k: Fix QMI memory reuse logicMuhammad Usama Anjum
Firmware requests 2 segments at first. The first segment is of 6799360 whose allocation fails due to dma remapping not available. The success is returned to firmware. Then firmware asks for 22 smaller segments instead of 2 big ones. Those get allocated successfully. At suspend/ hibernation time, these segments aren't freed as they will be reused by firmware after resuming. After resuming, the firmware asks for the 2 segments again with the first segment of 6799360 size. Since chunk->vaddr is not NULL, the type and size are compared with the previous type and size to know if it can be reused or not. Unfortunately, it is detected that it cannot be reused and this first smaller segment is freed. Then we continue to allocate 6799360 size memory which fails and ath11k_qmi_free_target_mem_chunk() is called which frees the second smaller segment as well. Later success is returned to firmware which asks for 22 smaller segments again. But as we had freed 2 segments already, we'll allocate the first 2 new smaller segments again and reuse the remaining 20. Hence 20 small segments are being reused instead of 22. Add skip logic when vaddr is set, but size/type don't match. Use the same skip and success logic as used when dma_alloc_coherent() fails. By skipping, the possibility of resume failure due to kernel failing to allocate memory for QMI can be avoided. kernel: ath11k_pci 0000:03:00.0: failed to allocate dma memory for qmi (524288 B type 1) ath11k_pci 0000:03:00.0: failed to allocate qmi target memory: -22 Tested-on: WCN6855 WLAN.HSP.1.1-03926.13-QCAHSPSWPL_V2_SILICONZ_CE-2.52297.6 Signed-off-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Reviewed-by: Baochen Qiang <quic_bqiang@quicinc.com> Link: https://patch.msgid.link/20250428080242.466901-1-usama.anjum@collabora.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
