wifi: cfg80211/mac80211: move puncturing into chandef Aloka originally suggested that puncturing should be part of the chandef, so that it's treated correctly. At the time, I disagreed and it ended up not part of the chandef, but I've now realized that this was wrong. Even for clients, the RX, and perhaps more importantly, CCA configuration needs to take puncturing into account. Move puncturing into the chandef, and adjust all the code accordingly. Also add a few tests for puncturing in chandef compatibility checking.

wifi: ath12k: move peer delete after vdev stop of station for WCN7850 In current code, when STA/P2P Client connect to AP/P2P GO, the WMI command sequence is: peer_create->vdev_start->vdev_up And sequence of STA/P2P Client disconnect from AP/P2P GO is: peer_delete->vdev_down->vdev_stop This sequence of disconnect is not opposite of connect. For STA or P2P GO, bss peer is not needed by firmware during handling vdev stop command. So with this sequence, STA and P2P GO can work normally. But for P2P Client, firmware needs bss peer in some functions during handling vdev stop command. The opposite sequence of disconnect should be: vdev_down->vdev_stop->peer_delete So change the sequence of disconnect as above opposite sequence for WCN7850.

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.

wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware crash In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has been disabled for size reduction. Currently ath12k always enables EHT PHY mode during vdev start but with the special firmware that will cause a firmware crash during vdev start in firmware initialisation. This is because the firmware will use the EHT mode to allocate resources but as the EHT mode is not available in the firmware, there's an internal conflict and the firmware will crash. To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware supports EHT. If EHT is not supported downgrade the PHY mode to HE (IEEE 802.11ax). This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled for QCN9274, then eht_cap->has_eht will always set for it, and the logic of this patch will not take effect and the PHY mode will not down grade for it.

wifi: ath12k: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 Currently mac80211 will send 3 scan request for each scan of WCN7850, they are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN7850 will cache the RNR IE(Reduced Neighbor Report element) which exist in the beacon of 2.4 GHz/5 GHz of the AP which is co-located with 6 GHz, and then use the cache to scan in 6 GHz band scan if the 6 GHz scan is in the same scan with the 2.4 GHz/5 GHz band, this will helpful to search more AP of 6 GHz. Also it will decrease the time cost of scan because firmware will use dual-band scan for the 2.4 GHz/5 GHz, it means the 2.4 GHz and 5 GHz scans are doing simultaneously. Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 since it supports 2.4 GHz/5 GHz/6 GHz in a single wiphy/ieee80211_hw. This does not impact QCN9274, because it is not single_phy, so does not have 2.4 GHz/5 GHz/6 GHz in the same wiphy, then it does not match the condition and then IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS will not set for QCN9274.

wifi: ath12k: indicate to mac80211 scan complete with aborted flag for ATH12K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath12k_mac_op_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath12k_mac_scan_finish() which is called from ath12k_core_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH12K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH12K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

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 radar detection in 160 MHz Radar detection fails in the secondary 80 MHz when the the AP's primary 80 MHz is in non-DFS region in 160 MHz. This is due to WMI channel flag WMI_CHAN_INFO_DFS_FREQ2 is not set properly in case of the primary 80 MHz is in non-DFS region. HALPHY detects the radar pulses in the secondary 80 MHz only when WMI_CHAN_INFO_DFS_FREQ2 is set.

wifi: ath12k: trigger station disconnect on hardware restart Currently after the hardware restart triggered from the driver, the station interface connection remains intact, since a disconnect trigger is not sent to userspace. This can lead to a problem in targets where the wifi mac sequence is added by the firmware. After the target restart, its wifi mac sequence number gets reset to zero. Hence AP to which our device is connected will receive frames with a wifi mac sequence number jump to the past, thereby resulting in the AP dropping all these frames, until the frame arrives with a wifi mac sequence number which AP was expecting. To avoid such frame drops, its better to trigger a station disconnect upon target hardware restart which can be done with API ieee80211_reconfig_disconnect exposed to mac80211.

Sometimes the workqueue does not finish Tx immediately, then it lead after the next step of vdev delete finished, it start to send the management packet to firmware and lead firmware crash. ieee80211_set_disassoc() have logic of ieee80211_flush_queues() after it send_deauth_disassoc() to ath12k, its purpose is make sure the deauth was actually sent, so it need to change ath12k to match the purpose of mac80211. To address these issues wait for Tx management as well as Tx data packets.

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.
