* 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. |

/** |
|
* DOC: station table - AP Station in STA mode |
|
* |
|
* %iwl_mvm_vif includes the index of the AP station in the fw's STA table: |
|
* %ap_sta_id. To get the point to the corresponding %ieee80211_sta, |
|
* &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. |
|

/** |
|
* 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 |
|
* %iwl_mvm_up. |

/** |
|
* 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. |
