2025-05-16wifi: ath12k: fix macro definition HAL_RX_MSDU_PKT_LENGTH_GETKang Yang
Currently, HAL_RX_MSDU_PKT_LENGTH_GET uses u32_get_bits to obtain the MSDU length from the MSDU description. This is not right. Because all halphy descriptions are little endian. So use le32_get_bits for HAL_RX_MSDU_PKT_LENGTH_GET.

2025-04-07wifi: ath12k: Fix memory leak during vdev_id mismatchP Praneesh
Currently driver enables vdev_id check as part of the bank configuration in ath12k_dp_tx_get_vdev_bank_config(). This check ensures that the vdev_id configured in the bank register aligns with the vdev_id in the packet's address search table within the firmware. If there is a mismatch, the firmware forwards the packet with the HTT status HAL_WBM_REL_HTT_TX_COMP_STATUS_VDEVID_MISMATCH. Since driver does not handle this vdev_id mismatch HTT status, the corresponding buffers are not freed properly, causing a memory leak. Fix this issue by adding handling to free the buffers when a vdev_id mismatch HTT status is encountered.

2025-01-26wifi: ath12k: Handle end reason for the monitor destination ringP Praneesh
Currently, the monitor destination ring's descriptor includes a 2-bit field for the end reason. Out of all the end reason values, hardware uses HAL_MON_FLUSH_DETECTED and HAL_MON_PPDU_TRUNCATED to indicate buffers that should not be processed due to system level errors. Driver should not process entries with these end reasons, as they contain junk values. However, the current code lacks end reason-specific checks for the monitor destination ring, leading to the processing of invalid buffers. Fix this by adding checks for these two end reasons during the reaping phase. Free the skb if either HAL_MON_FLUSH_DETECTED or HAL_MON_PPDU_TRUNCATED is detected, preventing the driver from processing invalid entries.

There is mismatch between the format of monitor destination TLVs received and the expected format by the current implementation.

2024-06-26wifi: ath12k: fix peer metadata parsingKarthikeyan Periyasamy
Currently, the Rx data path only supports parsing peer metadata of version zero. However, the QCN9274 platform configures the peer metadata version as V1B. When V1B peer metadata is parsed using the version zero logic, invalid data is populated, causing valid packets to be dropped. To address this issue, refactor the peer metadata version and add the version based parsing to populate the data from peer metadata correctly.

2024-01-18wifi: ath12k: add support for BA1024Baochen Qiang
Currently the maximum block ACK window size supported is 256. This results in that, when connected to an AP which supports larger BA sizes like BA512 or BA1024, only BA256 is established, leading to a lower peak throughput.

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.
