| /** |
| * 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!): |
| */ |
| |
| /** |
| * Max Tx window size is the max number of contiguous TFDs that the scheduler |
| * can keep track of at one time when creating block-ack chains of frames. |
| * Note that "64" matches the number of ack bits in a block-ack packet. |
