2025-06-07wifi: ath12k: fix GCC_GCC_PCIE_HOT_RST definition for WCN7850Baochen Qiang
GCC_GCC_PCIE_HOT_RST is wrongly defined for WCN7850, causing kernel crash on some specific platforms. Since this register is divergent for WCN7850 and QCN9274, move it to register table to allow different definitions. Then correct the register address for WCN7850 to fix this issue. Note IPQ5332 is not affected as it is not PCIe based device.

2025-05-16wifi: ath12k: add interrupt configuration for mon status ringKang Yang
The monitor mode design is: 1. Hardware captures packets on the air. 2. Hardware stores the packets into related rings. 3. When the ring buffer reaches the interrupt threshold, it triggers the interrupt. 4. Reap and process the ring buffer in ath12k_dp_service_srng(). Here the interrupt thresholds are intr_timer_thres_us, low_threshold and intr_batch_cntr_thres_entries. An interrupt will be triggered once: 1. Number of packets in the ring reaches intr_batch_cntr_thres_entries. 2. Number of packets in the ring reaches low_threshold(by timer). 3. Timer reaches intr_timer_thres_us. So, add interrupt configuration for the mon status ring, then start to process ring buffers when the interrupt arrives.

When userspace tries to set country code by NL80211_REGDOM_SET_BY_USER hint(like iw reg set XX), it will pass new country code to ath12k. Then ath12k will set this new country code to firmware by WMI_SET_INIT_COUNTRY_CMDID. For AP based chips(QCN92xx), WMI_SET_INIT_COUNTRY_CMDID is the correct command. However, for STATION based chips(WCN7850), it need to use WMI_SET_CURRENT_COUNTRY_CMDID. Add flag current_cc_support in hardware parameters. It is used to distinguish AP/STA platform. After that, the firmware will work normally and the regulatory feature works well for WCN7850.

During PCI based hardware device start up, ASPM is disabled for all. And once firmware is ready, it is restored back. However, not all hardwares (for example QCN9274) supports ASPM. Hence there is a need to conditionally restore ASPM back. Or else, for such hardwares, issue can be seen during sending and receiving packets. Introduce a new hardware param supports_aspm which identifies whether a given hardware supports ASPM or not and then accordingly restore it.

2024-08-05wifi: ath12k: use 128 bytes aligned iova in transmit path for WCN7850Baochen Qiang
In transmit path, it is likely that the iova is not aligned to PCIe TLP max payload size, which is 128 for WCN7850. Normally in such cases hardware is expected to split the packet into several parts in a manner such that they, other than the first one, have aligned iova. However due to hardware limitations, WCN7850 does not behave like that properly with some specific unaligned iova in transmit path. This easily results in target hang in a KPI transmit test: packet send/receive failure, WMI command send timeout etc. Also fatal error seen in PCIe level: ... Capabilities: ... ... DevSta: ... FatalErr+ ... ... ... Work around this by manually moving/reallocating payload buffer such that we can map it to a 128 bytes aligned iova. The moving requires sufficient head room or tail room in skb: for the former we can do ourselves a favor by asking some extra bytes when registering with mac80211, while for the latter we can do nothing. Moving/reallocating buffer consumes additional CPU cycles, but the good news is that an aligned iova increases PCIe efficiency. In my tests on some X86 platforms the KPI results are almost consistent. Since this is seen only with WCN7850, add a new hardware parameter to differentiate from others.

2024-02-02wifi: ath12k: remove hal_desc_sz from hw paramsRaj Kumar Bhagat
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. The hardware param hal_desc_sz value cannot be constant for the same hardware. It depends on the size of rx_desc structure which may change based on firmware capability to support word mask subscription. Hence, remove hal_desc_sz from hardware param and add hal_rx_ops to get the size of rx_desc in run time.

2024-02-02wifi: ath12k: fix firmware assert during insmod in memory segment modeAaradhana Sahu
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.

Add support to process WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit. If this service bit is set by firmware, then it expects host to set rx_peer_meta_data_ver in wmi_resource_config's flags2 with value 3 for QCN9274 to indicate as V1B meta version. If this is not set firmware crash is seen during peer addition. Hence, if WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit is set by firmware, set correct peer metadata version to avoid firmware crash.

2023-12-18wifi: ath12k: add support to search regdb data in board-2.bin for WCN7850Wen Gong
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.

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.

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.
