2024-03-14wifi: ath11k: implement handling of P2P NoA eventKang Yang
The NoA(Notice of Absence) attribute is used by the P2P Group Owner to signal its absence due to power save timing, concurrent operation, or off-channel scanning. It is also used in the P2P Presence Request-Response mechanism. The NoA attribute shall be present in the P2P IE in the beacon frames transmitted by a P2P Group Owner when a NoA schedule is being advertised, or when the CTWindow is non-zero. So add support to update P2P information after P2P GO is up through event WMI_P2P_NOA_EVENTID, and always put it in probe resp. Create p2p.c and p2p.h for P2P related functions and definitions.

2024-03-12wifi: ath11k: don't force enable power save on non-running vdevsBaochen Qiang
Currently we force enable power save on non-running vdevs, this results in unexpected ping latency in below scenarios: 1. disable power save from userspace. 2. trigger suspend/resume. With step 1 power save is disabled successfully and we get a good latency: PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=5.13 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=5.45 ms 64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=5.99 ms 64 bytes from 192.168.1.1: icmp_seq=4 ttl=64 time=6.34 ms 64 bytes from 192.168.1.1: icmp_seq=5 ttl=64 time=4.47 ms 64 bytes from 192.168.1.1: icmp_seq=6 ttl=64 time=6.45 ms While after step 2, the latency becomes much larger: PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=17.7 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=15.0 ms 64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=14.3 ms 64 bytes from 192.168.1.1: icmp_seq=4 ttl=64 time=16.5 ms 64 bytes from 192.168.1.1: icmp_seq=5 ttl=64 time=20.1 ms The reason is, with step 2, power save is force enabled due to vdev not running, although mac80211 was trying to disable it to honor userspace configuration: ath11k_pci 0000:03:00.0: wmi cmd sta powersave mode psmode 1 vdev id 0 Call Trace: ath11k_wmi_pdev_set_ps_mode ath11k_mac_op_bss_info_changed ieee80211_bss_info_change_notify ieee80211_reconfig ieee80211_resume wiphy_resume This logic is taken from ath10k where it was added due to below comment: Firmware doesn't behave nicely and consumes more power than necessary if PS is disabled on a non-started vdev. However we don't know whether such an issue also occurs to ath11k firmware or not. But even if it does, it's not appropriate because it goes against userspace, even cfg/mac80211 don't know we have enabled it in fact. Remove it to fix this issue. In this way we not only get a better latency, but also, and the most important, keeps the consistency between userspace and kernel/driver. The biggest price for that would be the power consumption, which is not that important, compared with the consistency.

2024-03-08wifi: ath10k: poll service ready message before failingBaochen Qiang
Currently host relies on CE interrupts to get notified that the service ready message is ready. This results in timeout issue if the interrupt is not fired, due to some unknown reasons. See below logs: [76321.937866] ath10k_pci 0000:02:00.0: wmi service ready event not received ... [76322.016738] ath10k_pci 0000:02:00.0: Could not init core: -110 And finally it causes WLAN interface bring up failure.

2024-03-04wifi: mac80211: introduce a feature flag for quiet in CSAJohannes Berg
When doing CSA in multi-link, there really isn't a need to stop transmissions entirely. Add a feature flag for drivers to indicate they can handle quiet in CSA (be it by parsing themselves, or by implementing drv_pre_channel_switch()), to make that possible. Also clean up the csa_block_tx handling: it clearly cannot handle multi-link due to the way queues are stopped, move it to the sdata. Drivers should be doing it themselves for working properly during CSA in MLO anyway. Also rename it to indicate that it reflects TX was blocked at mac80211.

Allow calling cfg80211_defragment_element() without an output buffer, where it then just returns the required output size.
