Ideally, we would like to allocate one queue 85 * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2 86 * even if it also needs to send traffic to a sleeping STA1, without being 87 * blocked by the sleeping station. 88 * 89 * Although the queues in DQA mode are dynamically allocated, there are still 90 * some queues that are statically allocated: 91 * TXQ #0 - command queue 92 * TXQ #1 - aux frames 93 * TXQ #2 - P2P device frames 94 * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames 95 * TXQ #4 - BSS DATA frames queue 96 * TXQ #5-8 - Non-QoS and MGMT frames queue pool 97 * TXQ #9 - P2P GO/SoftAP probe responses 98 * TXQ #10-31 - DATA frames queue pool 99 * The queues are dynamically taken from either the MGMT frames queue pool or 100 * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every 101 * queue. 102 * 103 * When a frame for a previously unseen RA/TID comes in, it needs to be deferred 104 * until a queue is allocated for it, and only then can be TXed. Therefore, it 105 * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called 106 * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames. 107 * 108 * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT 109 * queues in the pool. If there is no longer a free MGMT queue to allocate, a 110 * queue will be allocated from the DATA pool instead. Since QoS NDPs can create 111 * a problem for aggregations, they too will use a MGMT queue. 112 * 113 * When adding a STA, a DATA queue is reserved for it so that it can TX from 114 * it. If no such free queue exists for reserving, the STA addition will fail. 115 * 116 * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a 117 * new RA/TID comes in for an existing STA, one of the STA's queues will become 118 * shared and will serve more than the single TID (but always for the same RA!). 119 * 120 * When a RA/TID needs to become aggregated, no new queue is required to be 121 * allocated, only mark the queue as aggregated via the ADD_STA command. Note, 122 * however, that a shared queue cannot be aggregated, and only after the other 123 * TIDs become inactive and are removed - only then can the queue be 124 * reconfigured and become aggregated. 125 * 126 * When removing a station, its queues are returned to the pool for reuse. Here 127 * we also need to make sure that we are synced with the worker thread that TXes 128 * the deferred frames so we don't get into a situation where the queues are 129 * removed and then the worker puts deferred frames onto the released queues or 130 * tries to allocate new queues for a STA we don't need anymore. 131 */ 132 133 /** 134 * DOC: station table - introduction 135 * 136 * The station table is a list of data structure that reprensent the stations. 137 * In STA/P2P client mode, the driver will hold one station for the AP/ GO. 138 * In GO/AP mode, the driver will have as many stations as associated clients. 139 * All these stations are reflected in the fw's station table. The driver 140 * keeps the fw's station table up to date with the ADD_STA command. Stations 141 * can be removed by the REMOVE_STA command. 142 * 143 * All the data related to a station is held in the structure %iwl_mvm_sta 144 * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area. 145 * This data includes the index of the station in the fw, per tid information 146 * (sequence numbers, Block-ack state machine, etc...). The stations are 147 * created and deleted by the %sta_state callback from %ieee80211_ops. 148 * 149 * The driver holds a map: %fw_id_to_mac_id that allows to fetch a 150 * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw 151 * station index. That way, the driver is able to get the tid related data in 152 * O(1) in time sensitive paths (Tx / Tx response / BA notification). These 153 * paths are triggered by the fw, and the driver needs to get a pointer to the 154 * %ieee80211 structure. This map helps to get that pointer quickly. 155 */ 156 157 /** 158 * DOC: station table - locking 159 * 160 * As stated before, the station is created / deleted by mac80211's %sta_state 161 * callback from %ieee80211_ops which can sleep. The next paragraph explains 162 * the locking of a single stations, the next ones relates to the station 163 * table. 164 * 165 * The station holds the sequence number per tid. So this data needs to be 166 * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack 167 * information (the state machine / and the logic that checks if the queues 168 * were drained), so it also needs to be accessible from the Tx response flow. 169 * In short, the station needs to be access from sleepable context as well as 170 * from tasklets, so the station itself needs a spinlock. 171 * 172 * The writers of %fw_id_to_mac_id map are serialized by the global mutex of 173 * the mvm op_mode. This is possible since %sta_state can sleep. 174 * The pointers in this map are RCU protected, hence we won't replace the 175 * station while we have Tx / Tx response / BA notification running. 176 * 177 * If a station is deleted while it still has packets in its A-MPDU queues, 178 * then the reclaim flow will notice that there is no station in the map for 179 * sta_id and it will dump the responses. 180 */ 181 182 /** 183 * DOC: station table - internal stations 184 * 185 * The FW needs a few internal stations that are not reflected in 186 * mac80211, such as broadcast station in AP / GO mode, or AUX sta for 187 * scanning and P2P device (during the GO negotiation). 188 * For these kind of stations we have %iwl_mvm_int_sta struct which holds the 189 * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta. 190 * Usually the data for these stations is static, so no locking is required, 191 * and no TID data as this is also not needed. 192 * One thing to note, is that these stations have an ID in the fw, but not 193 * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id 194 * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of 195 * pointers from this mapping need to check that the value is not error 196 * or NULL. 197 * 198 * Currently there is only one auxiliary station for scanning, initialized 199 * on init. 200 */ 201 202 /** 203 * DOC: station table - AP Station in STA mode 204 * 205 * %iwl_mvm_vif includes the index of the AP station in the fw's STA table: 206 * %ap_sta_id. To get the point to the corresponding %ieee80211_sta, 207 * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove 208 * the AP station from the fw before setting the MAC context as unassociated. 209 * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is 210 * removed by mac80211, but the station won't be removed in the fw until the 211 * VIF is set as unassociated.

The flush can be done synchronously against the 220 * fw. 221 * Drain means that the fw will drop all the frames sent to a specific station. 222 * This is useful when a client (if we are IBSS / GO or AP) disassociates. 223 */ 224 225 /** 226 * DOC: station table - fw restart 227 * 228 * When the fw asserts, or we have any other issue that requires to reset the 229 * driver, we require mac80211 to reconfigure the driver. Since the private 230 * data of the stations is embed in mac80211's %ieee80211_sta, that data will 231 * not be zeroed and needs to be reinitialized manually. 232 * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us 233 * that we must not allocate a new sta_id but reuse the previous one. This 234 * means that the stations being re-added after the reset will have the same 235 * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id 236 * map, since the stations aren't in the fw any more.

All frames on 246 * shared queues (i.e. non-aggregation queues) to that station will be dropped 247 * by the fw (%TX_STATUS_FAIL_DEST_PS failure code). 248 * 249 * AMPDUs are in a separate queue that is stopped by the fw. We just need to 250 * let mac80211 know when there are frames in these queues so that it can 251 * properly handle trigger frames. 252 * 253 * When a trigger frame is received, mac80211 tells the driver to send frames 254 * from the AMPDU queues or sends frames to non-aggregation queues itself, 255 * depending on which ACs are delivery-enabled and what TID has frames to 256 * transmit. Note that mac80211 has all the knowledge since all the non-agg 257 * frames are buffered / filtered, and the driver tells mac80211 about agg 258 * frames). The driver needs to tell the fw to let frames out even if the 259 * station is asleep.
