/**
|
|
* DOC: DQA - Dynamic Queue Allocation -introduction
|
|
*
|
|
* Dynamic Queue Allocation (AKA "DQA") is a feature implemented in iwlwifi
|
|
* driver to allow dynamic allocation of queues on-demand, rather than allocate
|
|
* them statically ahead of time. Ideally, we would like to allocate one queue
|
|
* per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2
|
|
* even if it also needs to send traffic to a sleeping STA1, without being
|
|
* blocked by the sleeping station.
|
|
*
|
|
* Although the queues in DQA mode are dynamically allocated, there are still
|
|
* some queues that are statically allocated:
|
|
* TXQ #0 - command queue
|
|
* TXQ #1 - aux frames
|
|
* TXQ #2 - P2P device frames
|
|
* TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames
|
|
* TXQ #4 - BSS DATA frames queue
|
|
* TXQ #5-8 - Non-QoS and MGMT frames queue pool
|
|
* TXQ #9 - P2P GO/SoftAP probe responses
|
|
* TXQ #10-31 - DATA frames queue pool
|
|
* The queues are dynamically taken from either the MGMT frames queue pool or
|
|
* the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every
|
|
* queue.
|
|
*
|
|
* When a frame for a previously unseen RA/TID comes in, it needs to be deferred
|
|
* until a queue is allocated for it, and only then can be TXed. Therefore, it
|
|
* is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called
|
|
* %mvm->add_stream_wk later allocates the queues and TXes the deferred frames.
|
|
*
|
|
* For convenience, MGMT is considered as if it has TID=8, and go to the MGMT
|
|
* queues in the pool. If there is no longer a free MGMT queue to allocate, a
|
|
* queue will be allocated from the DATA pool instead. Since QoS NDPs can create
|
|
* a problem for aggregations, they too will use a MGMT queue.
|
|
*
|
|
* When adding a STA, a DATA queue is reserved for it so that it can TX from
|
|
* it. If no such free queue exists for reserving, the STA addition will fail.
|
|
*
|
|
* If the DATA queue pool gets exhausted, no new STA will be accepted, and if a
|
|
* new RA/TID comes in for an existing STA, one of the STA's queues will become
|
|
* shared and will serve more than the single TID (but always for the same RA!).
|
|
*
|
|
* When a RA/TID needs to become aggregated, no new queue is required to be
|
|
* allocated, only mark the queue as aggregated via the ADD_STA command. Note,
|
|
* however, that a shared queue cannot be aggregated, and only after the other
|
|
* TIDs become inactive and are removed - only then can the queue be
|
|
* reconfigured and become aggregated.
|
|
*
|
|
* When removing a station, its queues are returned to the pool for reuse. Here
|
|
* we also need to make sure that we are synced with the worker thread that TXes
|
|
* the deferred frames so we don't get into a situation where the queues are
|
|
* removed and then the worker puts deferred frames onto the released queues or
|
|
* tries to allocate new queues for a STA we don't need anymore.

/**
|
|
* DOC: station table - introduction
|
|
*
|
|
* The station table is a list of data structure that reprensent the stations.
|
|
* In STA/P2P client mode, the driver will hold one station for the AP/ GO.
|
|
* In GO/AP mode, the driver will have as many stations as associated clients.
|
|
* All these stations are reflected in the fw's station table. The driver
|
|
* keeps the fw's station table up to date with the ADD_STA command. Stations
|
|
* can be removed by the REMOVE_STA command.
|
|
*
|
|
* All the data related to a station is held in the structure %iwl_mvm_sta
|
|
* which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.
|
|
* This data includes the index of the station in the fw, per tid information
|
|
* (sequence numbers, Block-ack state machine, etc...). The stations are
|
|
* created and deleted by the %sta_state callback from %ieee80211_ops.
|
|
*
|
|
* The driver holds a map: %fw_id_to_mac_id that allows to fetch a
|
|
* %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw
|
|
* station index. That way, the driver is able to get the tid related data in
|
|
* O(1) in time sensitive paths (Tx / Tx response / BA notification). These
|
|
* paths are triggered by the fw, and the driver needs to get a pointer to the
|
|
* %ieee80211 structure. This map helps to get that pointer quickly.
|

|
|
|
|
/**
|
|
* DOC: station table - locking
|
|
*
|
|
* As stated before, the station is created / deleted by mac80211's %sta_state
|
|
* callback from %ieee80211_ops which can sleep. The next paragraph explains
|
|
* the locking of a single stations, the next ones relates to the station
|
|
* table.
|
|
*
|
|
* The station holds the sequence number per tid. So this data needs to be
|
|
* accessed in the Tx path (which is softIRQ). It also holds the Block-Ack
|
|
* information (the state machine / and the logic that checks if the queues
|
|
* were drained), so it also needs to be accessible from the Tx response flow.
|
|
* In short, the station needs to be access from sleepable context as well as
|
|
* from tasklets, so the station itself needs a spinlock.
|
|
*
|
|
* The writers of %fw_id_to_mac_id map are serialized by the global mutex of
|
|
* the mvm op_mode. This is possible since %sta_state can sleep.
|
|
* The pointers in this map are RCU protected, hence we won't replace the
|
|
* station while we have Tx / Tx response / BA notification running.
|
|
*
|
|
* If a station is deleted while it still has packets in its A-MPDU queues,
|
|
* then the reclaim flow will notice that there is no station in the map for
|
|
* sta_id and it will dump the responses.

/**
|
|
* DOC: station table - internal stations
|
|
*
|
|
* The FW needs a few internal stations that are not reflected in
|
|
* mac80211, such as broadcast station in AP / GO mode, or AUX sta for
|
|
* scanning and P2P device (during the GO negotiation).
|
|
* For these kind of stations we have %iwl_mvm_int_sta struct which holds the
|
|
* data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.
|
|
* Usually the data for these stations is static, so no locking is required,
|
|
* and no TID data as this is also not needed.
|
|
* One thing to note, is that these stations have an ID in the fw, but not
|
|
* in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id
|
|
* we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of
|
|
* pointers from this mapping need to check that the value is not error
|
|
* or NULL.
|
|
*
|
|
* Currently there is only one auxiliary station for scanning, initialized
|
|
* on init.

|
* &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove
|
|
* the AP station from the fw before setting the MAC context as unassociated.
|
|
* Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is
|
|
* removed by mac80211, but the station won't be removed in the fw until the
|
|
* VIF is set as unassociated. Then, %ap_sta_id will be invalidated.

|

* Flush means that all the frames in the SCD queue are dumped regardless the

* station to which they were sent. We do that when we disassociate and before
|
|
* we remove the STA of the AP. The flush can be done synchronously against the
|

* fw.
|
|
* Drain means that the fw will drop all the frames sent to a specific station.

/**
|
|
* DOC: station table - fw restart
|
|
*
|
|
* When the fw asserts, or we have any other issue that requires to reset the
|
|
* driver, we require mac80211 to reconfigure the driver. Since the private
|
|
* data of the stations is embed in mac80211's %ieee80211_sta, that data will
|
|
* not be zeroed and needs to be reinitialized manually.
|
|
* %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us
|
|
* that we must not allocate a new sta_id but reuse the previous one. This
|
|
* means that the stations being re-added after the reset will have the same
|
|
* place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id
|
|
* map, since the stations aren't in the fw any more. Internal stations that
|
|
* are not added by mac80211 will be re-added in the init flow that is called
|
|
* after the restart: mac80211 call's %iwl_mvm_mac_start which calls to

|
|
|
|
/**
|
|
* DOC: AP mode - PS
|
|
*
|
|
* When a station is asleep, the fw will set it as "asleep". All frames on
|
|
* shared queues (i.e. non-aggregation queues) to that station will be dropped
|
|
* by the fw (%TX_STATUS_FAIL_DEST_PS failure code).
|
|
*
|
|
* AMPDUs are in a separate queue that is stopped by the fw. We just need to
|
|
* let mac80211 know when there are frames in these queues so that it can
|
|
* properly handle trigger frames.
|
|
*
|
|
* When a trigger frame is received, mac80211 tells the driver to send frames
|
|
* from the AMPDU queues or sends frames to non-aggregation queues itself,
|
|
* depending on which ACs are delivery-enabled and what TID has frames to
|
|
* transmit. Note that mac80211 has all the knowledge since all the non-agg
|
|
* frames are buffered / filtered, and the driver tells mac80211 about agg
|
|
* frames). The driver needs to tell the fw to let frames out even if the
|
|
* station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count.
|
|
*
|
|
* When we receive a frame from that station with PM bit unset, the driver
|
|
* needs to let the fw know that this station isn't asleep any more. This is
|
|
* done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the
|
|
* station's wakeup.
|
|
*
|
|
* For a GO, the Service Period might be cut short due to an absence period
|
|
* of the GO. In this (and all other cases) the firmware notifies us with the
|
|
* EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we
|
|
* already sent to the device will be rejected again.
