2025-03-25wifi: ath12k: enable ath12k AHB supportBalamurugan S
Currently only PCI devices are supported in Ath12k driver. Refactor Ath12k module_init and module_exit to include Ath12k AHB support. Add Ath12k AHB support in Kconfig with dependency on Remoteproc driver. Ath12k AHB support relies on remoteproc driver for firmware download, power up/down etc. Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1 Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1 Signed-off-by: Balamurugan S <quic_bselvara@quicinc.com> Co-developed-by: P Praneesh <quic_ppranees@quicinc.com> Signed-off-by: P Praneesh <quic_ppranees@quicinc.com> Reviewed-by: Vasanthakumar Thiagarajan <vasanthakumar.thiagarajan@oss.qualcomm.com> Signed-off-by: Raj Kumar Bhagat <quic_rajkbhag@quicinc.com> Link: https://patch.msgid.link/20250321-ath12k-ahb-v12-13-bb389ed76ae5@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>

Currently, peer extended Rx statistics are not supported. Therefore, expose peer extended Rx statistics support through debugfs, allowing users to enable or disable the collection of statistics information. After that the statistics information can be dumped through debugfs. Below are the debugfs commands exposed.

2025-01-22wifi: ath12k: add factory test mode supportAaradhana Sahu
Add support to process factory test mode commands(FTM) for calibration. By default firmware start with MISSION 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. All ath12k test mode interface related commands specified in enum ath_tm_cmd. When start command ATH_TM_CMD_TESTMODE_START is received, ar state is set to test Mode and FTM daemon sends test mode command to wifi driver via cfg80211. Wifi driver sends these command to firmware as wmi events. If it is segmented commands it will be broken down into multiple segments and encoded with TLV header else it is sent to firmware as it is. Firmware response via UTF events, wifi driver creates skb and send to cfg80211, cfg80211 sends firmware response to FTM daemon via netlink message.

2024-10-16wifi: ath12k: Add firmware coredump collection supportSowmiya Sree Elavalagan
In case of firmware assert snapshot of firmware memory is essential for debugging. Add firmware coredump collection support for PCI bus. Collect RDDM and firmware paging dumps from MHI and pack them in TLV format and also pack various memory shared during QMI phase in separate TLVs. Add necessary header and share the dumps to user space using dev coredump framework. Coredump collection is disabled by default and can be enabled using menuconfig. Dump collected for a radio is 55 MB approximately.

2024-04-23wifi: ath12k: ACPI TAS supportLingbo Kong
Currently, ath12k does not support Time-Average-SAR (TAS). In order to enable TAS read the tables from ACPI and send them to the firmware using WMI_PDEV_SET_BIOS_INTERFACE_CMDID command. Besides, ath12k registers an ACPI event callback so that ACPI can notify ath12k to get the updated SAR power table and sends it to the firmware when the device state is changed. ACPI is only enabled for WCN7850 using struct ath12k_hw_params::acpi_guid field. Most likely QCN9274 will never support ACPI as the chip is not used in laptops.

The Notice of Absence (NoA) attribute is used by the P2P Group Owner to signal its absence due to power save timing, concurrent operation, or off-channel scanning. It is also used in the P2P Presence Request-Response mechanism. The NoA attribute shall be present in the P2P IE in the beacon frames transmitted by a P2P Group Owner when a NoA schedule is being advertised, or when the CTWindow is non-zero. So add support to update P2P information after P2P GO is up through event WMI_P2P_NOA_EVENTID, and always put it in probe resp. Create p2p.c and p2p.h for P2P related functions and definitions.

2024-02-02wifi: ath12k: add firmware-2.bin supportRaj Kumar Bhagat
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 ath12k 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 ath12k driver and provide the amss.bin firmware data and size to MHI using a pointer. Currently enum ath12k_fw_features is empty, the patches adding features will add the flags.

2022-11-29wifi: ath12k: driver for Qualcomm Wi-Fi 7 devicesKalle Valo
ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP and station; WCN7850 supports only station mode. Monitor mode is not (yet) supported. Only PCI bus devices are supported. ath12k is forked from an earlier version of ath11k. It was simpler to have a "clean start" for the new generation and not try to share the code with ath11k. This makes maintenance easier and avoids major changes in ath11k, which would have significantly increased the risk of regressions in existing setups. ath12k uses le32 and cpu_to_le32() macros to handle endian conversions, instead of using the firmware byte swap feature utilized by ath11k. There is only one kernel module, named ath12k.ko. Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but work is ongoing to add EHT mode (IEEE 802.11be) support. The size of the driver is ~41 kLOC and 45 files. To make the review easier, this initial version of ath12k does not support Device Tree, debugfs or any other extra features. Those will be added later, after ath12k is accepted to upstream. The driver is build tested by Intel's kernel test robot with both GCC and Clang. Sparse reports no warnings. The driver is mostly free of checkpatch warnings, albeit few of the warnings are omitted on purpose, list of them here: https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52 The driver has had multiple authors who are listed in alphabetical order below.
