101 | * Tx Scheduler | |
102 | * | |
a96a27f9 | 103 | * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs |
038669e4 EG |
104 | * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in |
105 | * host DRAM. It steers each frame's Tx command (which contains the frame | |
106 | * data) into one of up to 7 prioritized Tx DMA FIFO channels within the | |
107 | * device. A queue maps to only one (selectable by driver) Tx DMA channel, | |
108 | * but one DMA channel may take input from several queues. | |
109 | * | |
8ff84a2c | 110 | * Tx DMA FIFOs have dedicated purposes. |
038669e4 | 111 | * |
edc1a3a0 | 112 | * For 5000 series and up, they are used differently |
68198865 JB |
113 | * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c): |
114 | * | |
115 | * 0 -- EDCA BK (background) frames, lowest priority | |
116 | * 1 -- EDCA BE (best effort) frames, normal priority | |
117 | * 2 -- EDCA VI (video) frames, higher priority | |
118 | * 3 -- EDCA VO (voice) and management frames, highest priority | |
edc1a3a0 JB |
119 | * 4 -- unused |
120 | * 5 -- unused | |
121 | * 6 -- unused | |
68198865 JB |
122 | * 7 -- Commands |
123 | * | |
038669e4 | 124 | * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. |
68198865 JB |
125 | * In addition, driver can map the remaining queues to Tx DMA/FIFO |
126 | * channels 0-3 to support 11n aggregation via EDCA DMA channels. | |
038669e4 EG |
127 | * |
128 | * The driver sets up each queue to work in one of two modes: | |
129 | * | |
130 | * 1) Scheduler-Ack, in which the scheduler automatically supports a | |
131 | * block-ack (BA) window of up to 64 TFDs. In this mode, each queue | |
132 | * contains TFDs for a unique combination of Recipient Address (RA) | |
133 | * and Traffic Identifier (TID), that is, traffic of a given | |
134 | * Quality-Of-Service (QOS) priority, destined for a single station. | |
135 | * | |
136 | * In scheduler-ack mode, the scheduler keeps track of the Tx status of | |
137 | * each frame within the BA window, including whether it's been transmitted, | |
138 | * and whether it's been acknowledged by the receiving station. The device | |
139 | * automatically processes block-acks received from the receiving STA, | |
140 | * and reschedules un-acked frames to be retransmitted (successful | |
141 | * Tx completion may end up being out-of-order). | |
142 | * | |
143 | * The driver must maintain the queue's Byte Count table in host DRAM | |
8ff84a2c | 144 | * for this mode. |
038669e4 EG |
145 | * This mode does not support fragmentation. |
146 | * | |
147 | * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. | |
148 | * The device may automatically retry Tx, but will retry only one frame | |
149 | * at a time, until receiving ACK from receiving station, or reaching | |
150 | * retry limit and giving up. | |
151 | * | |
13bb9483 | 152 | * The command queue (#4/#9) must use this mode! |
038669e4 EG |
153 | * This mode does not require use of the Byte Count table in host DRAM. |
154 | * | |
155 | * Driver controls scheduler operation via 3 means: | |
156 | * 1) Scheduler registers | |
8ff84a2c | 157 | * 2) Shared scheduler data base in internal SRAM |
038669e4 EG |
158 | * 3) Shared data in host DRAM |
159 | * | |
160 | * Initialization: | |
161 | * | |
162 | * When loading, driver should allocate memory for: | |
163 | * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. | |
164 | * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory | |
165 | * (1024 bytes for each queue). | |
166 | * | |
167 | * After receiving "Alive" response from uCode, driver must initialize | |
13bb9483 | 168 | * the scheduler (especially for queue #4/#9, the command queue, otherwise |
038669e4 EG |
169 | * the driver can't issue commands!): |
