2024-12-19wifi: ath12k: Avoid explicit type cast in monitor status parse handlerKarthikeyan Periyasamy
Currently, monitor status parse procedure handles all the supported TLV tags. Each TLV tag has its own data structure for parsing. Now, this handler is passed the tlv_data as a u8 pointer, so explicit type cast conversion happens for every TLV tag parsing. Therefore, avoid the explicit type conversion by changing the tlv_data type from a u8 pointer to a const void pointer.

2024-12-19wifi: ath12k: fix incorrect TID updation in DP monitor status pathKarthikeyan Periyasamy
Currently, an incorrect TID value gets populated in the monitor status Rx path due to an incorrect bitmap value given to the ffs() built-in helper function. Therefore, avoid the decrement and directly provide the TID bitmap to the ffs() built-in helper function for the correct TID update in the monitor status Rx path.

2024-12-19wifi: ath12k: Add support for parsing 64-bit TLVsP Praneesh
There is mismatch between the format of monitor destination TLVs received and the expected format by the current implementation. The received TLVs are in 64-bit format, while the implementation is designed to handle 32-bit TLVs. This leads to incorrect parsing. Fix it by adding support for parsing 64-bit TLVs.

2024-10-23wifi: ath12k: fix A-MSDU indication in monitor modeKang Yang
In monitor mode, host will reap MSDUs and then the MSDUs with same PPDU ID will be aggregated into an A-MSDU in ath12k_dp_mon_rx_merg_msdus(). However, ath12k_dp_mon_rx_merg_msdus() doesn't calculate the total length of the A-MSDU. This causes Wireshark to display the A-MSDU incorrectly. Therefore, need to add calculation of the A-MSDU length.

2024-10-23wifi: ath12k: use tail MSDU to get MSDU informationKang Yang
When receiving a packet in monitor mode, hardware will fill status information msdu_end for MSDUs. Then host can use these status information to get specific information about this packet, such as l3 offset, bandwidth, mcs, packet type. If this packet is composed of multiple MSDUs, then hardware will only fill status information for the last(tail) MSDU. At this time, MSDU information is uncertain for others MSDUs. But current code use the first MSDU in monitor mode, so will get the wrong information. Fix it by getting msdu information from last(tail) msdu.

2024-10-16wifi: ath12k: prepare sta data structure for MLO handlingSriram R
To prepare the driver for MLO support, split the driver sta data structure to scale for multiple links. This requires changing the use of arsta to per link and not per hw which can now comprise of multiple links. Also since most configurations from mac80211 are done per link, do refactoring of the driver functions to apply these configurations at link level. Split struct ath12k_sta, which is the driver private of struct ieee80211_sta, to store link specific information as struct ath12k_link_sta. For default use cases struct ath12k_sta will have a preallocated link sta called deflink which will be used by non ML STAs and the first link sta of ML STA. With MLO support to be added, remaining link stas will allocated during state change where new STA is added. These link stas will be freed when STA is deleted. Current ath12k_sta(arsta) structure: +-----------------+ +----------------+ | | | | | ieee80211_sta | | ieee80211_sta | | private data | | private data | | | | | | ath12k_sta | | ath12k_sta | | (arsta) | | (arsta) | |+---------------+| | +-------------+| || *arvif (link || | |*arvif (link || || vif of an ar || | | vif of an ar|| || say 5GHz) || | | say 6GHz) || |+---------------+| | +-------------+| +-----------------+ +----------------+ New struct ath12k_sta (ahsta) containing ath12k_link_sta(s) (arsta) (deflink is preallocated member which is always the first link if ieee80211_sta is ML STA and is the only link sta otherwise): +---------------------------------------+ | ieee80211_sta | | private data | | | | ath12k_sta (ahsta) | | +-------------------------------------+ | | ath12k_link_sta deflink (arsta) | | | | | | *arvif (link vif of ar (5GHz)) | | +-------------------------------------+ | +-------------------------------------+ | | ath12k_link_sta *link (arsta) | | | | | | *arvif (link vif of ar (6GHz)) | | | | | +-------------------------------------+ | | +---------------------------------------+ To refactor existing ath12k_sta to make use of link stas, following changes are made: 1. Limit struct ieee80211_sta argument mac80211 ops unless otherwise really required. 2. struct ath12k_sta, now called by variable name arsta, stores multiple arstas (struct ah12k_link_sta) and also has a back pointer to struct ath12k_sta. 3. Pass struct ath12k_link_sta to mac functions that passed struct ieee80211_sta argument and fetch struct ath12k_sta (ahsta) and struct ieee80211_sta(sta) internally. This is done to avoid passing link id in all the functions and performing validation across these functions. Rather the validation and sta to arsta conversion can be done only at the mac80211 ops. 4. In this patchset, only ahsta->deflink is used to be on par with the existing code. When MLO support is added the link id will be used to fetch the arsta. 5. Change ath12k_sta_to_arsta() to ath12k_vif_to_ahsta() to fetch the ML level sta. The link sta can be fetched from ahsta->link[], or the deflink can be accessed via ahsta->deflink. API to access link sta (arsta) by passing link_id can be introduced with MLO Support. 6. The ieee80211_sta can be accessed from ahsta using ath12k_ahsta_to_sta() 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: Sriram R <quic_srirrama@quicinc.com> Co-developed-by: Rameshkumar Sundaram <quic_ramess@quicinc.com> Signed-off-by: Rameshkumar Sundaram <quic_ramess@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://patch.msgid.link/20241015171416.518022-4-kvalo@kernel.org Signed-off-by: Jeff Johnson <quic_jjohnson@quicinc.com>

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.

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.

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.
