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: Refactor the mac80211 hw access from link/radio Currently, mac80211 hardware accesses link/radio structure directly in multiple locations. Introduce helper function to avoid this direct access, as this change will facilitate refactoring for Multi-link operation support.

wifi: ath12k: avoid repeated hw access from ar Currently, the helper functions are accessing mac80211 hw data from the radio (ar) structure repeatedly. So optimize these helper functions by storing mac80211 hw data locally and accessing it directly.

wifi: ath12k: Optimize the mac80211 hw data access Currently mac80211 hw data is accessed by convert the hw to radio (ar) structure and then radio to hw structure which is not necessary in some places where mac80211 hw data is already present. So in that kind of places avoid the conversion and directly access the mac80211 hw data.

wifi: ath12k: add parsing of phy bitmap for reg rules Certain regulatory domains could put restrictions on phy mode operation. For example, in a few countries HE/EHT Operation is not allowed. For such countries, firmware indicates this via phy bitmap in each reg rule. Currently, there is no logic to parse this info and then pass it on to the cfg80211/regulatory. Add parsing of this phy bitmap from the regulatory channel change event and then accordingly map it to cfg80211/regulatory flags and pass it on to it. While at it, correct typo in debug print: s/dsf/dfs.

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.
