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.

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.

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.

With previous patch "wifi: ath11k: move update channel list from update reg worker to reg notifier", ath11k_reg_update_chan_list() will be called during reg_process_self_managed_hint(). reg_process_self_managed_hint() will hold rtnl_lock all the time. But ath11k_reg_update_chan_list() may increase the occupation time of rtnl_lock, because when wait flag is set, wait_for_completion_timeout() will be called during 11d/hw scan. Should minimize the occupation time of rtnl_lock as much as possible to avoid interfering with rest of the system. So move the update channel list operation to a new worker, so that wait_for_completion_timeout() won't be called and will not increase the occupation time of rtnl_lock.

2024-11-06wifi: ath11k: Suspend hardware before firmware mode off for WCN6750Balaji Pothunoori
During rmmod, the ath11k host driver sends a QMI MODE OFF command to firmware. As part of this command, firmware initiates WLAN de-initialization and accesses certain UMAC registers during this process. Currently, on WCN6750 WLAN hardware, the system is in a sleep state when firmware receives the QMI MODE OFF command. This results in a firmware/hardware reset while accessing the UMAC hardware registers during sleep state. To avoid this, add logic to send WCN6750 hardware specific WMI_PDEV_SUSPEND_AND_DISABLE_INTR command to firmware prior to sending the QMI MODE OFF command. This will cause firmware to cease all activities and put the device in a powered-on state that prevents access to registers which have been powered off.

WCN6750 firmware crashes because of num_vdevs changed from 4 to 17 in ath11k_init_wmi_config_qca6390() as the ab->hw_params.num_vdevs is 17. This is caused by commit f019f4dff2e4 ("wifi: ath11k: support 2 station interfaces") which assigns ab->hw_params.num_vdevs directly to config->num_vdevs in ath11k_init_wmi_config_qca6390(), therefore WCN6750 firmware crashes as it can't support such a big num_vdevs. Fix it by assign 3 to num_vdevs in hw_params for WCN6750 as 3 is sufficient too.

2024-04-09wifi: ath11k: support hibernationBaochen Qiang
Now that all infrastructure is in place and ath11k is fixed to handle all the corner cases, power down the ath11k firmware during suspend and power it back up during resume. This fixes the problem when using hibernation with ath11k PCI devices. For suspend, two conditions needs to be satisfied: 1. since MHI channel unprepare would be done in late suspend stage, ath11k needs to get all QMI-dependent things done before that stage. 2. and because unprepare MHI channels requires a working MHI stack, ath11k is not allowed to call mhi_power_down() until that finishes. So the original suspend callback is separated into two parts: the first part handles all QMI-dependent things in suspend callback; while the second part powers down MHI in suspend_late callback. This is valid because kernel calls ath11k's suspend callback before all suspend_late callbacks, making the first condition happy. And because MHI devices are children of ath11k device (ab->dev), kernel guarantees that ath11k's suspend_late callback is called after QRTR's suspend_late callback, this satisfies the second condition. Above analysis also applies to resume process. so the original resume callback is separated into two parts: the first part powers up MHI stack in resume_early callback, this guarantees MHI stack is working when QRTR tries to prepare MHI channels (kernel calls QRTR's resume_early callback after ath11k's resume_early callback, due to the child-father relationship); the second part waits for the completion of restart, which won't fail now since MHI channels are ready for use by QMI. Another notable change is in power down path, we tell mhi_power_down() to not to destroy MHI devices, making it possible for QRTR to help unprepare/prepare MHI channels, and finally get us rid of the probe-defer issue when resume. Also change related code due to interface changes.

QCA2066 is a PCI based DBS device. It is very similar to WCN6855 overall: they share the same PCI device ID, the same major and minor version numbers, the same register address, and same HAL descriptors etc. The most significant difference is that QCA2066 supports 3-antenna configuration while WCN6855 does not. To differentiate them, subversion numbers are used. Currently four numbers are used by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1 and 0x1019D0E1.

2023-10-25wifi: ath11k: add firmware-2.bin supportAnilkumar Kolli
Firmware IE containers can dynamically provide various information what firmware supports. Also it can embed more than one image so updating firmware is easy, user just needs to update one file in /lib/firmware/. The firmware API 2 or higher will use the IE container format, the current API 1 will not use the new format but it still is supported for some time. Firmware API 2 files are named as firmware-2.bin (which contains both amss.bin and m3.bin images) and API 1 files are amss.bin and m3.bin. Currently ath11k PCI driver provides firmware binary (amss.bin) path to MHI driver, MHI driver reads firmware from filesystem and boots it. Add provision to read firmware files from ath11k driver and provide the amss.bin firmware data and size to MHI using a pointer. Currently enum ath11k_fw_features is empty, the patches adding features will add the flags. With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB firmware files are used. But AHB devices can use future additions to the meta data, for example in enum ath11k_fw_features.

Add support to process factory test mode commands (FTM) for calibration. By default firmware start with NORMAL mode and to process the FTM commands firmware needs to be restarted in FTM mode using module parameter ftm_mode. The pre-request is all the radios should be down before starting the test. When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state is set to Test Mode. If the FTM command or event length is greater than 256 bytes, it will be broken down into multiple segments and encoded with TLV header if it is segmented commands, else it is sent to firmware as it is. On receiving UTF event from firmware, if it is segmented event, the driver will wait until it receives all the segments and notify the complete data to user application. In case the segmented sequence are missed or lost from the firmware, driver will skip the already received partial data. In case of unsegmented UTF event from firmware, driver notifies the data to the user application as it comes. Applications handles the data further.

Fine Timing Measurement(FTM) support is used to measure round trip time between two nodes. Enable FTM responder feature using hw_params on supported device. Since FTM functionality is offloaded to firmware, adding the interface allows user space to enable or disable FTM responder. Also add support for advertising the same in extended capabilities.

2022-11-08wifi: ath11k: Trigger sta disconnect on hardware restartYoughandhar Chintala
Currently after the hardware restart triggered from the driver, the station interface connection remains intact, since a disconnect trigger is not sent to userspace. This can lead to a problem in targets where the wifi mac sequence is added by the firmware. After the target restart, its wifi mac sequence number gets reset to zero. Hence AP to which our device is connected will receive frames with a wifi mac sequence number jump to the past, thereby resulting in the AP dropping all these frames, until the frame arrives with a wifi mac sequence number which AP was expecting. To avoid such frame drops, its better to trigger a station disconnect upon target hardware restart which can be done with API ieee80211_reconfig_disconnect exposed to mac80211. The other targets are not affected by this change, since the hardware params flag is not set.

During firmware recovery, the monitor interface is not getting created in the driver and firmware since the respective flags are not updated properly. So after firmware recovery is successful, when monitor interface is brought down manually, firmware assertion is observed, since we are trying to bring down the interface which is not yet created in the firmware. Fix this by updating the monitor flags properly per phy#, during firmware recovery.
