Realtek RFE (RF Front End) parameters can consider Thailand individually now, so we add it into regulation type enum. Then, we map country code TH to RTW89_ETSI/RTW89_THAILAND according to band. The RF TX power tables will add entries for RTW89_THAILAND in the following. Signed-off-by:

MCC (multi-channel concurrency) supports two combinations as below. * P2P-GO + STA * P2P-GC + STA We add the corresponding ieee80211_iface_limit for it into ieee80211_iface_combination. Besides, for multiple channels, it must run with mac80211 chanctx. So, only with it, ieee80211_iface_combination can allow MCC case. Signed-off-by:

During (TDMA-based) MCC (multi-channel concurrency), the below two cases might not have a good behavior on channel usage. * ROC (remain on channel) * HW scan So, we tend to separate them from MCC. The two cases would expect to operate the channel to which they want. However, during MCC, channels are scheduled by FW MCC state mechanism. So, channels cannot be controlled explicitly. To avoid the two cases from operating wrong channels with chance, we pause MCC (essentially stop FW MCC) once the two cases are coming. And then, we proceed MCC again (essentially restart FW MCC) once the two cases finish. Signed-off-by:

Under TDMA-based MCC (multi-channel concurrency), there are two roles, reference and auxiliary. We arrange MCC timeline based on time domain of reference role. Then, we calculate NoA start time according to MCC timeline. Besides, when MCC runs GO+STA mode, we plan an offset between GO time domain and STA time domain to make their TBTTs have a time gap. However, if GO is auxiliary role instead of reference role, NoA start time is described by STA time domain instead of GO time domain. To fix this, we apply the offset mentioned above to NoA start time to convert time domain from STA to GO. Signed-off-by:

WCN7850 and QCN9274 currently use the same structure rx_msdu_end_qcn9274 for msdu_end. But content of msdu_end on WCN7850 is different from that of QCN9274. Need to update it for WCN7850, otherwise will get the wrong values when using it. For example, TID is no longer in WCN7850's msdu_end. But ath12k_dp_rx_process_err() and ath12k_dp_rx_process_wbm_err() still get TID from msdu_end. So an uncertain value will be used in these two functions on WCN7850. Therefore, add new structure rx_msdu_end_wcn7850 for WCN7850. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 Signed-off-by:

Mac80211 does not set flags BSS_CHANGED_FILS_DISCOVERY and BSS_CHANGED_UNSOL_BCAST_PROBE_RESP if there are no updates to FILS discovery and unsolicited broadcast probe response transmission configurations respectively. For BSS change operations such as channel switch, this results in the transmissions getting stopped because the driver does not send WMI command to firmware if the flags are not set. Remove the checks for the flags to always send the existing configuration to firmware. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Signed-off-by:

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.

ath12k prints "Received scan event for unknown vdev" when doing the following test: 1. trigger scan 2. wait 0.2 second 3. iw reg set is issued or 11d scan complete event is sent from firmware Reason is: When iw reg set is issues or the 11d scan complete event is received, the new country code will be set to the firmware, and the new regdomain info indicated to ath12k, then the new channel list will be sent to the firmware. The firmware will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID which is used for the new channel list, and the state of ath12k is ATH12K_SCAN_RUNNING, then ath12k_get_ar_on_scan_abort() returns NULL and ath12k_scan_event() returns at this point and does not indicate scan completion to mac80211. Indicate scan completion to mac80211 and get rid of the "Received scan event for unknown vdev" print for the above case.

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.

When firmware crashed while channel switch running, recovery starts in ath12k. Then ieee80211_sta_connection_lost() will be called by function ieee80211_restart_work() in mac80211. And then many WMI command timeout because firmware is crashed. Each WMI command cost 3 seconds, then the total time will be large and leads recovery fail. Hence change to set value ATH12K_FLAG_CRASH_FLUSH early and then ath12k_wmi_cmd_send() will not wait 3 seconds, then recovery will be started quickly and success.

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.

There's a race with runtime PM getting enabled by userspace: - we rescan the PCI bus - this creates the new PCI device including its sysfs representation - udev sees the new device, and the (OS-specific?) scripting enables runtime PM by writing to power/control; this can happen _before_ the next step - this will runtime-suspend the device which saves the config space, including the BAR0 that wasn't assigned yet - the bus rescan assigns resources to the devices and writes them to the config space of the device (but not the runtime-pm saved copy) - the driver binds and this disallows runtime PM, so the device is resumed, restoring the (incomplete!) config space - the driver cannot work due to BAR0 not being configured Fixing the actual race is hard and deep in the PCI layer, though probably should be done for upstream as well; perhaps runtime PM should only be allowed after resource assignment, or some other TBD way. Work around this in the driver for now by simply (re-)assigning BAR0 when the driver initializes, if it's unset. Signed-off-by:
