2023-10-23wifi: iwlwifi: mvm: implement new firmware API for statisticsAnjaneyulu
The new firmware API uses a new command and notification, the command configures in which statistics types driver is interested and the notification is sent periodically. An additional change in the API is that most of the statistics data is accumulated and reported by the firmware per MLO link. Implement new command and notification handlers and adjust to per-link statistics.

2023-10-23wifi: iwlwifi: mvm: fix regdb initializationGregory Greenman
In order to get regulatory domain, driver sends MCC_UPDATE_CMD to the FW. One of the parameters in the response is the status which can tell if the regdomain has changed or not. When iwl_mvm_init_mcc() is called during iwl_op_mode_mvm_start(), then sband is still NULL and channel parameters (i.e. chan->flags) cannot be initialized. When, further in the flow, iwl_mvm_update_mcc() is called during iwl_mvm_up(), it first checks if the regdomain has changed and then skips the update if it remains the same. But, since channel parameters weren't initialized yet, the update should be forced in this codepath. Fix that by adding a corresponding parameter to iwl_mvm_init_fw_regd().

2023-10-23wifi: iwlwifi: disable multi rx queue for 9000Emmanuel Grumbach
Multi rx queue allows to spread the load of the Rx streams on different CPUs. 9000 series required complex synchronization mechanisms from the driver side since the hardware / firmware is not able to provide information about duplicate packets and timeouts inside the reordering buffer. Users have complained that for newer devices, all those synchronization mechanisms have caused spurious packet drops. Those packet drops disappeared if we simplify the code, but unfortunately, we can't have RSS enabled on 9000 series without this complex code. Remove support for RSS on 9000 so that we can make the code much simpler for newer devices and fix the bugs for them. The down side of this patch is a that all the Rx path will be routed to a single CPU, but this has never been an issue, the modern CPUs are just fast enough to cope with all the traffic.

2023-10-23wifi: iwlwifi: make time_events MLO awareMiri Korenblit
As session protection API is moving to be per link instead of per mac, move the time events to be per link too. Since there is only one concurrent time event per mac, it feels unnecessary to have the time_event as a member of iwl_mvm_link_info. (That way we will have to iterate over all links each time we want to clear a time event, and also we will need mac80211 to tell us the link id when mgd_tx_complete() is called.) So leave this as a member of iwl_mvm_vif, but add the link id to the time_event structure. The link id in time_event will only be maintained and used for: 1. When SESSION_PROTECTION_CMD is supported (before it, we don't have MLO) 2. For time_events of types SESSION_PROTECT_CONF_ASSOC, SESSION_PROTECT_CONF_P2P_DEVICE_DISCOV, and SESSION_PROTECT_CONF_P2P_GO_NEGOTIATION (not for aux roc/ Hot Spot time_events). For P2P, non-MLO connections, and pre-MLD API, deflink id, meaning 0, will be used Signed-off-by: Miri Korenblit <miriam.rachel.korenblit@intel.com> Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Link: https://lore.kernel.org/r/20231017115047.21496bcacb18.I79d037325b4fae4c12a22d9477e53fc9c537ad46@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2023-10-23wifi: iwlwifi: mvm: fix iwl_mvm_mac_flush_sta()Johannes Berg
When I implemented iwl_mvm_mac_flush_sta() I completely botched it; it basically always happens after the iwl_mvm_sta_pre_rcu_remove() call, and that already clears mvm->fw_id_to_mac_id[] entries, so we cannot rely on those at iwl_mvm_mac_flush_sta() time. This means it never did anything. Fix this by just going through the station IDs and now with the new API for iwl_mvm_flush_sta(), call those.

2023-10-23wifi: iwlwifi: mvm: fix the PHY context resolution for p2p deviceEmmanuel Grumbach
We seem to have an issue in case we had a BSS and a P2P device on channel 1 and then, the P2P device gets an ROC on channel 6. We would change the channel of the PHY context to channel 6 even if the BSS was using that same PHY context. Revamp that code and don't try to change a PHY context, it doesn't mean much for the firmware anyway. Just remove it and allocate a new one. This makes the logic easier to follow.

2023-10-23wifi: iwlwifi: mvm: don't add dummy phy contextEmmanuel Grumbach
From its very first stages of development, iwlmvm added all the PHY context immediately upon firmware boot. Then, all we needed to do is to modify the contexts. This was fine if the addition of a PHY context that we don't need is free. This was true until now. Newer devices will run calibrations upon the addition of a PHY context. Change the way we work with PHY context in iwlmvm. Fortunately, we already have all the ref counting in place so that it is not very hard to do. Also, since we now remove the PHY context before the link is removed (but after it has been de-activated of course), it'll confuse the firmware if we put the late phy_id into the LINK command that removes the link. Change this to put an invalid phy_id just like we do when we add a link that has no PHY context yet.

bss_info_changed() callback of mac80211 was originally in both MLD and non-MLD API. Therefore, we extracted the common part to a function which receives a callback structure with the mode-specific (non-MLO\MLO) ops. Eventually, for MLO API, bss_info_changed() callback was split into 2 callbacks: link_info_changed() and vif_cfg_changed() so it is no longer in use for MLO, only for non-MLO.

If the channel bandwidth is greater or equal than 80MHz, enable FILS DF transmittion, even if the control channel is non-PSC. That's because that in 80MHz there must be a sub 20MHz PSC channel, and since the FILS DF is duplicated on all sub 20MHz channels, within the 80MHz (hence it will be sent on a PSC channel). Also, if FILS DF Tx is enabled, always configure the firmware with the actual channel bandwidth, even before there is a connected client (rather than the minimum bandwidth e.g. 20MHz), since FILS DF transmission on a PSC channel take presedent over power consumption.

2023-09-11wifi: iwlwifi: mvm: increase session protection after CSAJohannes Berg
In the spec, CSA is defined roughly as follows: - TBTT x: beacon with CSA, count=n (old channel) - TBTT x+1: beacon with CSA, count=n-1 (old channel) - TBTT x+n-1: beacon with CSA, count=1 (old channel) "A Channel Switch Count field set to 1 indicates that the switch occurs immediately before the next TBTT. - TBTT x+n: beacon without CSA (new channel) When we detect it, we currently schedule the CSA event to be at 10 TUs before TBTT x+n-1, for a beacon interval, to give us quiet time. When this event *starts*, we currently notify mac80211 that the channel switch happened, which causes us to add a session protection event to listen for the first beacon (and enable TX etc. when that arrives). We don't even ask for a notification when this event ends so the code that handles that is effectively dead code. The session protection duration is 3 beacon intervals, scheduled at 10 TU before TBTT x+n-1. It will thus end just before TBTT x+n+2. Unfortunately, if the AP doesn't transmit or we miss just the first two beacons on the new channel, then this will cause us to disconnect. Or even just one, if the AP isn't quite aligned with the TBTT after the switch. However, listening to the _end_ of the time event isn't what we want either, because we want all the new PHY and other config that needs to come from mac80211 to start early, so we have a head-start for the new channel, since we're not going to use the old one anyway for this time. So since we don't really have anything better to do at this time, and this is relatively rare, just make the session protection use 5x the beacon interval instead of just 3x, so it's more likely we catch a beacon even if the AP neglected to send it, or we just miss it.

2023-06-21wifi: iwlwifi: mvm: check only affected linksJohannes Berg
When hostapd starts up, it may start up with only one link while the other is still scanning for overlapping BSSes. A station might start to connect at this point, but we run into this warning instead. Since there's no need to check for _all_ links, restrict the check to just the affected links that the STA will be using.
