/* * Tx Scheduler * * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in * host DRAM. It steers each frame's Tx command (which contains the frame * data) into one of up to 7 prioritized Tx DMA FIFO channels within the * device. A queue maps to only one (selectable by driver) Tx DMA channel, * but one DMA channel may take input from several queues. * * Tx DMA FIFOs have dedicated purposes. * * For 5000 series and up, they are used differently * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c): * * 0 -- EDCA BK (background) frames, lowest priority * 1 -- EDCA BE (best effort) frames, normal priority * 2 -- EDCA VI (video) frames, higher priority * 3 -- EDCA VO (voice) and management frames, highest priority * 4 -- unused * 5 -- unused * 6 -- unused * 7 -- Commands * * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. * In addition, driver can map the remaining queues to Tx DMA/FIFO * channels 0-3 to support 11n aggregation via EDCA DMA channels. * * The driver sets up each queue to work in one of two modes: * * 1) Scheduler-Ack, in which the scheduler automatically supports a * block-ack (BA) window of up to 64 TFDs. In this mode, each queue * contains TFDs for a unique combination of Recipient Address (RA) * and Traffic Identifier (TID), that is, traffic of a given * Quality-Of-Service (QOS) priority, destined for a single station. * * In scheduler-ack mode, the scheduler keeps track of the Tx status of * each frame within the BA window, including whether it's been transmitted, * and whether it's been acknowledged by the receiving station. The device * automatically processes block-acks received from the receiving STA, * and reschedules un-acked frames to be retransmitted (successful * Tx completion may end up being out-of-order). * * The driver must maintain the queue's Byte Count table in host DRAM * for this mode. * This mode does not support fragmentation. * * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. * The device may automatically retry Tx, but will retry only one frame * at a time, until receiving ACK from receiving station, or reaching * retry limit and giving up. * * The command queue (#4/#9) must use this mode! * This mode does not require use of the Byte Count table in host DRAM. * * Driver controls scheduler operation via 3 means: * 1) Scheduler registers * 2) Shared scheduler data base in internal SRAM * 3) Shared data in host DRAM * * Initialization: * * When loading, driver should allocate memory for: * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory * (1024 bytes for each queue). * * After receiving "Alive" response from uCode, driver must initialize * the scheduler (especially for queue #4/#9, the command queue, otherwise * the driver can't issue commands!):
