83 | * DOC: station table - introduction | |
84 | * | |
85 | * The station table is a list of data structure that reprensent the stations. | |
86 | * In STA/P2P client mode, the driver will hold one station for the AP/ GO. | |
87 | * In GO/AP mode, the driver will have as many stations as associated clients. | |
88 | * All these stations are reflected in the fw's station table. The driver | |
89 | * keeps the fw's station table up to date with the ADD_STA command. Stations | |
90 | * can be removed by the REMOVE_STA command. | |
91 | * | |
92 | * All the data related to a station is held in the structure %iwl_mvm_sta | |
93 | * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area. | |
94 | * This data includes the index of the station in the fw, per tid information | |
95 | * (sequence numbers, Block-ack state machine, etc...). The stations are | |
96 | * created and deleted by the %sta_state callback from %ieee80211_ops. | |
97 | * | |
98 | * The driver holds a map: %fw_id_to_mac_id that allows to fetch a | |
99 | * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw | |
100 | * station index. That way, the driver is able to get the tid related data in | |
101 | * O(1) in time sensitive paths (Tx / Tx response / BA notification). These | |
102 | * paths are triggered by the fw, and the driver needs to get a pointer to the | |
103 | * %ieee80211 structure. This map helps to get that pointer quickly. | |
104 | */ | |
105 | ||
106 | /** | |
107 | * DOC: station table - locking | |
108 | * | |
109 | * As stated before, the station is created / deleted by mac80211's %sta_state | |
110 | * callback from %ieee80211_ops which can sleep. The next paragraph explains | |
111 | * the locking of a single stations, the next ones relates to the station | |
112 | * table. | |
113 | * | |
114 | * The station holds the sequence number per tid. So this data needs to be | |
115 | * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack | |
116 | * information (the state machine / and the logic that checks if the queues | |
117 | * were drained), so it also needs to be accessible from the Tx response flow. | |
118 | * In short, the station needs to be access from sleepable context as well as | |
119 | * from tasklets, so the station itself needs a spinlock. | |
120 | * | |
121 | * The writers of %fw_id_to_mac_id map are serialized by the global mutex of | |
122 | * the mvm op_mode. This is possible since %sta_state can sleep. | |
123 | * The pointers in this map are RCU protected, hence we won't replace the | |
124 | * station while we have Tx / Tx response / BA notification running. | |
125 | * | |
126 | * If a station is deleted while it still has packets in its A-MPDU queues, | |
127 | * then the reclaim flow will notice that there is no station in the map for | |
128 | * sta_id and it will dump the responses. | |

131 | /** | |
132 | * DOC: station table - internal stations | |
133 | * | |
134 | * The FW needs a few internal stations that are not reflected in | |
135 | * mac80211, such as broadcast station in AP / GO mode, or AUX sta for | |
136 | * scanning and P2P device (during the GO negotiation). | |
137 | * For these kind of stations we have %iwl_mvm_int_sta struct which holds the | |
138 | * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta. | |
139 | * Usually the data for these stations is static, so no locking is required, | |
140 | * and no TID data as this is also not needed. | |
141 | * One thing to note, is that these stations have an ID in the fw, but not | |
142 | * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id | |
143 | * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of | |
144 | * pointers from this mapping need to check that the value is not error | |
145 | * or NULL. | |
146 | * | |
147 | * Currently there is only one auxiliary station for scanning, initialized | |
148 | * on init. | |

151 | /** | |
152 | * DOC: station table - AP Station in STA mode | |
153 | * | |
154 | * %iwl_mvm_vif includes the index of the AP station in the fw's STA table: | |
0d365ae5 | 155 | * %ap_sta_id. To get the point to the corresponding %ieee80211_sta, |
8ca151b5 JB |
156 | * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove |
157 | * the AP station from the fw before setting the MAC context as unassociated. | |
158 | * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is | |
159 | * removed by mac80211, but the station won't be removed in the fw until the | |
160 | * VIF is set as unassociated. Then, %ap_sta_id will be invalidated. | |

164 | * DOC: station table - Drain vs. Flush | |
165 | * | |
166 | * Flush means that all the frames in the SCD queue are dumped regardless the | |
167 | * station to which they were sent. We do that when we disassociate and before | |
168 | * we remove the STA of the AP. The flush can be done synchronously against the | |
169 | * fw. | |
170 | * Drain means that the fw will drop all the frames sent to a specific station. | |
171 | * This is useful when a client (if we are IBSS / GO or AP) disassociates. In | |
172 | * that case, we need to drain all the frames for that client from the AC queues | |
173 | * that are shared with the other clients. Only then, we can remove the STA in | |
174 | * the fw. In order to do so, we track the non-AMPDU packets for each station. | |
175 | * If mac80211 removes a STA and if it still has non-AMPDU packets pending in | |
176 | * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all | |
177 | * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped | |
178 | * (we know about it with its Tx response), we remove the station in fw and set | |
179 | * it as %NULL in %fw_id_to_mac_id: this is the purpose of | |
180 | * %iwl_mvm_sta_drained_wk. | |

183 | /** | |
184 | * DOC: station table - fw restart | |
185 | * | |
186 | * When the fw asserts, or we have any other issue that requires to reset the | |
187 | * driver, we require mac80211 to reconfigure the driver. Since the private | |
188 | * data of the stations is embed in mac80211's %ieee80211_sta, that data will | |
189 | * not be zeroed and needs to be reinitialized manually. | |
190 | * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us | |
191 | * that we must not allocate a new sta_id but reuse the previous one. This | |
192 | * means that the stations being re-added after the reset will have the same | |
193 | * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id | |
194 | * map, since the stations aren't in the fw any more. Internal stations that | |
195 | * are not added by mac80211 will be re-added in the init flow that is called | |
196 | * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to | |
197 | * %iwl_mvm_up. | |

3e56eadf JB |
203 | * When a station is asleep, the fw will set it as "asleep". All frames on |
204 | * shared queues (i.e. non-aggregation queues) to that station will be dropped | |
205 | * by the fw (%TX_STATUS_FAIL_DEST_PS failure code). | |
206 | * | |
8ca151b5 | 207 | * AMPDUs are in a separate queue that is stopped by the fw. We just need to |
3e56eadf | 208 | * let mac80211 know when there are frames in these queues so that it can |
8ca151b5 | 209 | * properly handle trigger frames. |
3e56eadf JB |
210 | * |
211 | * When a trigger frame is received, mac80211 tells the driver to send frames | |
212 | * from the AMPDU queues or sends frames to non-aggregation queues itself, | |
213 | * depending on which ACs are delivery-enabled and what TID has frames to | |
0d365ae5 | 214 | * transmit. Note that mac80211 has all the knowledge since all the non-agg |
3e56eadf JB |
215 | * frames are buffered / filtered, and the driver tells mac80211 about agg |
216 | * frames). The driver needs to tell the fw to let frames out even if the | |
217 | * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count. | |
218 | * | |
219 | * When we receive a frame from that station with PM bit unset, the driver | |
220 | * needs to let the fw know that this station isn't asleep any more. This is | |
0d365ae5 | 221 | * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the |
3e56eadf JB |
222 | * station's wakeup. |
223 | * | |
224 | * For a GO, the Service Period might be cut short due to an absence period | |
225 | * of the GO. In this (and all other cases) the firmware notifies us with the | |
226 | * EOSP_NOTIFICATION, and we notify mac80211 of that. Further frames that we | |
227 | * already sent to the device will be rejected again. | |
