128 * Tx Scheduler
129 *
a96a27f9 130 * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
038669e4
EG
131 * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
132 * host DRAM. It steers each frame's Tx command (which contains the frame
133 * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
134 * device. A queue maps to only one (selectable by driver) Tx DMA channel,
135 * but one DMA channel may take input from several queues.
136 *
8ff84a2c 137 * Tx DMA FIFOs have dedicated purposes.
038669e4 138 *
edc1a3a0 139 * For 5000 series and up, they are used differently
68198865
JB
140 * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
141 *
142 * 0 -- EDCA BK (background) frames, lowest priority
143 * 1 -- EDCA BE (best effort) frames, normal priority
144 * 2 -- EDCA VI (video) frames, higher priority
145 * 3 -- EDCA VO (voice) and management frames, highest priority
edc1a3a0
JB
146 * 4 -- unused
147 * 5 -- unused
148 * 6 -- unused
68198865
JB
149 * 7 -- Commands
150 *
038669e4 151 * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
68198865
JB
152 * In addition, driver can map the remaining queues to Tx DMA/FIFO
153 * channels 0-3 to support 11n aggregation via EDCA DMA channels.
038669e4
EG
154 *
155 * The driver sets up each queue to work in one of two modes:
156 *
157 * 1) Scheduler-Ack, in which the scheduler automatically supports a
158 * block-ack (BA) window of up to 64 TFDs. In this mode, each queue
159 * contains TFDs for a unique combination of Recipient Address (RA)
160 * and Traffic Identifier (TID), that is, traffic of a given
161 * Quality-Of-Service (QOS) priority, destined for a single station.
162 *
163 * In scheduler-ack mode, the scheduler keeps track of the Tx status of
164 * each frame within the BA window, including whether it's been transmitted,
165 * and whether it's been acknowledged by the receiving station. The device
166 * automatically processes block-acks received from the receiving STA,
167 * and reschedules un-acked frames to be retransmitted (successful
168 * Tx completion may end up being out-of-order).
169 *
170 * The driver must maintain the queue's Byte Count table in host DRAM
8ff84a2c 171 * for this mode.
038669e4
EG
172 * This mode does not support fragmentation.
173 *
174 * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
175 * The device may automatically retry Tx, but will retry only one frame
176 * at a time, until receiving ACK from receiving station, or reaching
177 * retry limit and giving up.
178 *
13bb9483 179 * The command queue (#4/#9) must use this mode!
038669e4
EG
180 * This mode does not require use of the Byte Count table in host DRAM.
181 *
182 * Driver controls scheduler operation via 3 means:
183 * 1) Scheduler registers
8ff84a2c 184 * 2) Shared scheduler data base in internal SRAM
038669e4
EG
185 * 3) Shared data in host DRAM
186 *
187 * Initialization:
188 *
189 * When loading, driver should allocate memory for:
190 * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs.
191 * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory
192 * (1024 bytes for each queue).
193 *
194 * After receiving "Alive" response from uCode, driver must initialize
13bb9483 195 * the scheduler (especially for queue #4/#9, the command queue, otherwise
038669e4
EG
196 * the driver can't issue commands!):
