Currently when wlan load up, station always use the 6 GHz reg rules of
AP mode by commit 91fa00fa6922 ("wifi: ath11k: add support to parse new
WMI event for 6 GHz"), then the tx power and frequency are not correct,
so fix it by dynamic switch to client mode LPI/SP/VLP for station after
interface added and connected for station.
v5: change per Kalle and rebased to ath.git ath-202306211808
1. ath11k_ieee80211_ap_pwr_type_convert() to ath11k_reg_ap_pwr_convert()
2. used list_first_entry_or_null() and add comments
3. ath11k_dbg() to ath11k_warn()
4. ath11k_hw_supports_6g_cc_ext() to ath11k_mac_supports_6g_cc_ext()
5. add mesh in commit log
v4: (NOT depends to any patch now).
1. removed patches which depends on
wifi: cfg80211: save Power Spectral Density (PSD) of the regulatory rule
https://lore.kernel.org/linux-wireless/[email protected]/
removed:
[v3,08/15] wifi: ath11k: save power spectral density(psd) of regulatory rule
[v3,09/15] wifi: ath11k: add parse of transmit power envelope element
[v3,10/15] wifi: ath11k: save max tx power in vdev start response event from firmware
[v3,11/15] wifi: ath11k: fill parameters for vdev_set_tpc_power wmi command
[v3,12/15] wifi: ath11k: add WMI_TLV_SERVICE_EXT_TPC_REG_SUPPORT service bit
[v3,13/15] wifi: ath11k: discard BSS_CHANGED_TXPOWER when EXT_TPC_REG_SUPPORT for 6 GHz
[v3,14/15] wifi: ath11k: add handler for WMI_VDEV_SET_TPC_POWER_CMDID
[v3,15/15] wifi: ath11k: send TPC power to firmware for 6 GHz station
2. rebased to ath.git ath-202304281700
3. deleted "wifi: ath11k: Add support to parse new wmi event for 6 GHz regulatory" which is alreay upstream.
link of v3:
[v3,00/15] wifi: ath11k: add support for 6 GHz station for various modes : LPI, SP and VLP
https://patchwork.kernel.org/project/linux-wireless/cover/[email protected]/
v3:
1. added "ath11k: fix a possible dead lock caused by ab->base_lock".
3. deleted "ath11k: add support for extended wmi service bit" which is alreay upstream.
v2:
1. change some minor comments by Kalle.
2. rebased to ath.git ath-202112220603
Baochen Qiang (1):
wifi: ath11k: fix a possible dead lock caused by ab->base_lock
Wen Gong (4):
wifi: ath11k: add support to select 6 GHz regulatory type
wifi: ath11k: store cur_regulatory_info for each radio
wifi: ath11k: update regulatory rules when interface added

2.40.1
The regulatory info of WMI_REG_CHAN_LIST_CC_EXT_EVENTID is not saved
in ath11k now, the info should be saved in ath11k. Save the info for
each radio and support switch regulatory rules dynamically.

2.40.1
From: Baochen Qiang <[email protected]>
spin_lock/spin_unlock are used in ath11k_reg_chan_list_event to
acquire/release ab->base_lock, for now this is safe because that
function is only called in soft IRQ context.
But ath11k_reg_chan_list_event() will be called from process
context in an upcoming patch, and this can result in a deadlock if
ab->base_lock is acquired in process context and then soft IRQ occurs
on the same CPU and tries to acquire that lock.
Fix it by using spin_lock_bh and spin_unlock_bh instead.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
Fixes: 69a0fcf8a9f2 ("ath11k: Avoid reg rules update during firmware recovery")
