wifi: ath12k: disable QMI PHY capability learn in split-phy QCN9274 QMI PHY capability learn is used to get PHY count information to support single/multi link operation (SLO/MLO) configuration. The QCN9274 dualmac firmware currently do not support SLO/MLO, if two PHYs are within the same chip. Due to this firmware crashes in split-phy QCN9274, while bringing up AP with MLO parameter enabled in QMI host capability request message. The QMI PHY capability learn is not required for split-phy QCN9274, if SLO/MLO is not supported within the same chip. Hence, disable QMI PHY capability learn support in split-phy QCN9274.

wifi: ath12k: Read board id to support split-PHY QCN9274 QCN9274 can support single-PHY or split-PHY architecture. Currently, only the single-PHY architecture is supported in ath12k. The split-PHY QCN9274 requires different AMSS firmware binary "amss_dualmac.bin". Hence, add support to read board id from OTP. Based on board id decide whether single-mac / dual-mac firmware needs to be downloaded to the target. Also, update HW param max_radios to support split-PHY in QCN9274.

wifi: ath12k: split hal_ops to support RX TLVs word mask compaction With word mask subscription support, the rx_desc structure will change. The fields in this structure rx_desc will be reduced to only the required fields. To make word mask subscription changes compatible with the older firmware version (firmware that does not support word mask subscription), two different structures of rx_desc will be required for the same hardware. Most of the hal_ops are directly related to rx_desc. Hence, split hal_ops into operations that are independent of rx_desc (hal_ops) and the operations that are directly dependent on rx_desc (hal_rx_ops). These hal_rx_ops depend on both hardware and firmware hence move them out of hw_params.

wifi: ath12k: fix firmware assert during insmod in memory segment mode 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.

wifi: ath12k: add firmware-2.bin support 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.

wifi: ath12k: Fix issues in channel list update Currently, the logic used to select the 6 GHz band is incorrect, which may cause 6 GHz supported channels to not be updated properly. This is because the 6 GHz Max frequency supported by the driver is being compared to the Max frequency supported on the board. If in some cases, the 6 GHz Max frequency supported on the board is less than the defined 6 GHz Max frequency, all 6 GHz channels are disabled. To address this, compare the max frequency supported by the board to the defined 6 GHz Minimum frequency by the driver. Similarly, when a dual mac card supports both 6 GHz and 5 GHz radios, if the 5 GHz radio gets enumerated first before 6 GHz, the checks in ath12k_mac_setup_channels_rates() can cause the 5 GHz channels which were enabled earlier to get disabled when the 6 GHz channel list is updated. This is because the Min 6 GHz frequency defined in the driver is 5945 MHz, which should be 5925 MHz since channel 2 is not considered currently, but the firmware can pass 5925 MHz as the minimum. Hence, update the Min frequency supported by the driver to 5925 MHz. In addition, ensure that the channel list update to firmware updates only the channels that the current radio (ar) supports rather than considering the wiphy support. This would be required when multiple pdevs are supported in a wiphy and they support different ranges of frequencies or bands as in single wiphy support.

wifi: ath12k: Introduce the container for mac80211 hw To support multi link operation, we need to combine all the link/pdev under a single wiphy. This avoids the overhead of synchronization across multiple hardware instances in both the cfg80211 and mac80211 layers. Currently, each link/pdev is registered as separate wiphy, tightly coupled with link/pdev/radio (ar) structure. To enable single wiphy registration within the chip, we decouple the wiphy data entity from the link/pdev/radio (ar) structure and move it under the chip (ab) structure with a new data container (ath12k_hw) structure. This approach improves scalability for future multi link operation support. mac80211 hw private data structure diagram ------------------------------------------ Now After +---------------------+ +---------------------+ |mac80211 hw priv data| |mac80211 hw priv data| | | | | | | | | | | | | | | | ath12k_hw (ah) | | | | | | | +-------------------> | | | ath12k (ar) | | +-------------+ | | | | | | | | | | | ath12k (ar) | | | | | | | | | | | | | | | | | +-------------+ | | | | | | | | | +---------------------+ +---------------------+ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Karthikeyan Periyasamy <quic_periyasa@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://msgid.link/20240118010320.3918136-3-quic_periyasa@quicinc.com

wifi: ath12k: add support to search regdb data in board-2.bin for WCN7850 Currently ath12k only downloads the same regdb.bin file for all WCN7850 chips, actually ath12k needs to distinguish all different WCN7850 chips. This is to re-use the string type which includes bus, chip id, board id, vendor, device, subsystem-vendor, subsystem-device and variant for WCN7850 to distinguish different regdb in board-2.bin. ath12k will first load board-2.bin and search in it for the regdb data with the above parameters. If matched with one regdb data, download it to firmware. And if not, download regdb.bin instead. Add enum value ATH12K_BD_IE_REGDB and enum type ath12k_bd_ie_regdb_type to distinguish regdb data and board data since they are in the same file board-2.bin.

wifi: ath12k: add string type to search board data in board-2.bin for WCN7850 Currently ath12k only supports string type with bus, chip id and board id such as "bus=ahb,qmi-chip-id=1,qmi-board-id=4" for AHB bus chip and "bus=pci,qmi-chip-id=0,qmi-board-id=255" for PCI bus chip in board-2.bin. For WCN7850, it is not enough to distinguish all different chips. Add a new string type which includes bus, chip id, board id, vendor, device, subsystem-vendor and subsystem-device for WCN7850. ath12k will first load board-2.bin and searches in it for the board data with the above parameters. If matched with one board data, ath12k downloads it to firmware. And if not, downloads board.bin instead.

In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath12k already defines a conversion function ath12k_vif_to_arvif() for a similar conversion. So introduce ath12k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function.

wifi: ath12k: add support for hardware rfkill for WCN7850 When hardware rfkill is enabled in the firmware, it will report the capability using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event to the host. Currently ath12k does not process this service capability. In order to support this, update ath12k to check if the capability is enabled, if so, send the GPIO information to firmware. When the firmware detects hardware rfkill is enabled by the user, it will report it using WMI_RFKILL_STATE_CHANGE_EVENTID. When ath12k receive the event, it will set the value of rfkill_radio_on based on whether radio_state is equal to WMI_RFKILL_RADIO_STATE_ON, then send WMI_PDEV_PARAM_RFKILL_ENABLE to firmware.

wifi: ath12k: fix firmware assert during channel switch for peer sta Currently, during change in bandwidth for peer sta, host sends the new value of channel width via WMI_PEER_CHWIDTH set peer param command alone. This can lead to firmware assert in some scenario since before the command, firmware was having value of channel width and its corresponding phymode. After the command, host tries to set the new value of channel width alone which can become incompatible when compared with its phymode. For example: Bandwidth Upgrade ~~~~~~~~~~~~~~~~~~ After association, sta is in 40 MHz bandwidth in 11ax-HE40 phymode. After bandwidth upgrades, sta moves to 80 MHz but as per phymode, max bandwidth is still 40 MHz. Hence, firmware assert is seen. So in this case first phymode should be moved to 11ax-HE80 followed by bandwidth change. Bandwidth Downgrade ~~~~~~~~~~~~~~~~~~ Similarly, reverse of above is also possible when sta is in 40 MHz bandwidth in 11ax-HE40 phymode. Bandwidth should be changed to 20 MHz and if host sends phymode first then, phymode will become 11ax-HE20 and will be incompatible with bandwidth value and hence firmware assert will be seen. Hence, in this case first channel width should be set followed by phymode. Fix this issue by sending WMI set peer param command for phymode as well as bandwidth based on the type of bandwidth change i.e upgrade or downgrade.

wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices 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.
