Ideally, we would like to allocate one queue27 * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA228 * even if it also needs to send traffic to a sleeping STA1, without being29 * blocked by the sleeping station.30 *31 * Although the queues in DQA mode are dynamically allocated, there are still32 * some queues that are statically allocated:33 * TXQ #0 - command queue34 * TXQ #1 - aux frames35 * TXQ #2 - P2P device frames36 * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames37 * TXQ #4 - BSS DATA frames queue38 * TXQ #5-8 - Non-QoS and MGMT frames queue pool39 * TXQ #9 - P2P GO/SoftAP probe responses40 * TXQ #10-31 - DATA frames queue pool41 * The queues are dynamically taken from either the MGMT frames queue pool or42 * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every43 * queue.44 *45 * When a frame for a previously unseen RA/TID comes in, it needs to be deferred46 * until a queue is allocated for it, and only then can be TXed. Therefore, it47 * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called48 * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames.49 *50 * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT51 * queues in the pool. If there is no longer a free MGMT queue to allocate, a52 * queue will be allocated from the DATA pool instead. Since QoS NDPs can create53 * a problem for aggregations, they too will use a MGMT queue.54 *55 * When adding a STA, a DATA queue is reserved for it so that it can TX from56 * it. If no such free queue exists for reserving, the STA addition will fail.57 *58 * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a59 * new RA/TID comes in for an existing STA, one of the STA's queues will become60 * shared and will serve more than the single TID (but always for the same RA!).61 *62 * When a RA/TID needs to become aggregated, no new queue is required to be63 * allocated, only mark the queue as aggregated via the ADD_STA command. Note,64 * however, that a shared queue cannot be aggregated, and only after the other65 * TIDs become inactive and are removed - only then can the queue be66 * reconfigured and become aggregated.67 *68 * When removing a station, its queues are returned to the pool for reuse. Here69 * we also need to make sure that we are synced with the worker thread that TXes70 * the deferred frames so we don't get into a situation where the queues are71 * removed and then the worker puts deferred frames onto the released queues or72 * tries to allocate new queues for a STA we don't need anymore.73 */74 75/**76 * DOC: station table - introduction77 *78 * The station table is a list of data structure that reprensent the stations.79 * In STA/P2P client mode, the driver will hold one station for the AP/ GO.80 * In GO/AP mode, the driver will have as many stations as associated clients.81 * All these stations are reflected in the fw's station table. The driver82 * keeps the fw's station table up to date with the ADD_STA command. Stations83 * can be removed by the REMOVE_STA command.84 *85 * All the data related to a station is held in the structure %iwl_mvm_sta86 * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area.87 * This data includes the index of the station in the fw, per tid information88 * (sequence numbers, Block-ack state machine, etc...). The stations are89 * created and deleted by the %sta_state callback from %ieee80211_ops.90 *91 * The driver holds a map: %fw_id_to_mac_id that allows to fetch a92 * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw93 * station index. That way, the driver is able to get the tid related data in94 * O(1) in time sensitive paths (Tx / Tx response / BA notification). These95 * paths are triggered by the fw, and the driver needs to get a pointer to the96 * %ieee80211 structure. This map helps to get that pointer quickly.97 */98 99/**100 * DOC: station table - locking101 *102 * As stated before, the station is created / deleted by mac80211's %sta_state103 * callback from %ieee80211_ops which can sleep. The next paragraph explains104 * the locking of a single stations, the next ones relates to the station105 * table.106 *107 * The station holds the sequence number per tid. So this data needs to be108 * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack109 * information (the state machine / and the logic that checks if the queues110 * were drained), so it also needs to be accessible from the Tx response flow.111 * In short, the station needs to be access from sleepable context as well as112 * from tasklets, so the station itself needs a spinlock.113 *114 * The writers of %fw_id_to_mac_id map are serialized by the global mutex of115 * the mvm op_mode. This is possible since %sta_state can sleep.116 * The pointers in this map are RCU protected, hence we won't replace the117 * station while we have Tx / Tx response / BA notification running.118 *119 * If a station is deleted while it still has packets in its A-MPDU queues,120 * then the reclaim flow will notice that there is no station in the map for121 * sta_id and it will dump the responses.122 */123 124/**125 * DOC: station table - internal stations126 *127 * The FW needs a few internal stations that are not reflected in128 * mac80211, such as broadcast station in AP / GO mode, or AUX sta for129 * scanning and P2P device (during the GO negotiation).130 * For these kind of stations we have %iwl_mvm_int_sta struct which holds the131 * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta.132 * Usually the data for these stations is static, so no locking is required,133 * and no TID data as this is also not needed.134 * One thing to note, is that these stations have an ID in the fw, but not135 * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id136 * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of137 * pointers from this mapping need to check that the value is not error138 * or NULL.139 *140 * Currently there is only one auxiliary station for scanning, initialized141 * on init.142 */143 144/**145 * DOC: station table - AP Station in STA mode146 *147 * %iwl_mvm_vif includes the index of the AP station in the fw's STA table:148 * %ap_sta_id. To get the point to the corresponding %ieee80211_sta,149 * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove150 * the AP station from the fw before setting the MAC context as unassociated.151 * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is152 * removed by mac80211, but the station won't be removed in the fw until the153 * VIF is set as unassociated. Then, %ap_sta_id will be invalidated.154 */155 156/**157 * DOC: station table - Drain vs. Flush158 *159 * Flush means that all the frames in the SCD queue are dumped regardless the160 * station to which they were sent. We do that when we disassociate and before161 * we remove the STA of the AP. The flush can be done synchronously against the162 * fw.163 * Drain means that the fw will drop all the frames sent to a specific station.164 * This is useful when a client (if we are IBSS / GO or AP) disassociates.165 */166 167/**168 * DOC: station table - fw restart169 *170 * When the fw asserts, or we have any other issue that requires to reset the171 * driver, we require mac80211 to reconfigure the driver. Since the private172 * data of the stations is embed in mac80211's %ieee80211_sta, that data will173 * not be zeroed and needs to be reinitialized manually.174 * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us175 * that we must not allocate a new sta_id but reuse the previous one. This176 * means that the stations being re-added after the reset will have the same177 * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id178 * map, since the stations aren't in the fw any more. Internal stations that179 * are not added by mac80211 will be re-added in the init flow that is called180 * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to181 * %iwl_mvm_up.182 */183 184/**185 * DOC: AP mode - PS186 *187 * When a station is asleep, the fw will set it as "asleep". All frames on188 * shared queues (i.e. non-aggregation queues) to that station will be dropped189 * by the fw (%TX_STATUS_FAIL_DEST_PS failure code).190 *191 * AMPDUs are in a separate queue that is stopped by the fw. We just need to192 * let mac80211 know when there are frames in these queues so that it can193 * properly handle trigger frames.194 *195 * When a trigger frame is received, mac80211 tells the driver to send frames196 * from the AMPDU queues or sends frames to non-aggregation queues itself,197 * depending on which ACs are delivery-enabled and what TID has frames to198 * transmit. Note that mac80211 has all the knowledge since all the non-agg199 * frames are buffered / filtered, and the driver tells mac80211 about agg200 * frames). The driver needs to tell the fw to let frames out even if the201 * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count.202 *203 * When we receive a frame from that station with PM bit unset, the driver204 * needs to let the fw know that this station isn't asleep any more.
