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!): */ #define SCD_MEM_LOWER_BOUND (0x0000) /** * 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. */ #define SCD_WIN_SIZE 64 #define SCD_FRAME_LIMIT 64 #define SCD_TXFIFO_POS_TID (0) #define SCD_TXFIFO_POS_RA (4) #define SCD_QUEUE_RA_TID_MAP_RATID_MSK (0x01FF) /* agn SCD */ #define SCD_QUEUE_STTS_REG_POS_TXF (0) #define SCD_QUEUE_STTS_REG_POS_ACTIVE (3) #define SCD_QUEUE_STTS_REG_POS_WSL (4) #define SCD_QUEUE_STTS_REG_POS_SCD_ACT_EN (19) #define SCD_QUEUE_STTS_REG_MSK (0x017F0000) #define SCD_QUEUE_CTX_REG1_CREDIT_POS (8) #define SCD_QUEUE_CTX_REG1_CREDIT_MSK (0x00FFFF00) #define SCD_QUEUE_CTX_REG1_SUPER_CREDIT_POS (24) #define SCD_QUEUE_CTX_REG1_SUPER_CREDIT_MSK (0xFF000000) #define SCD_QUEUE_CTX_REG2_WIN_SIZE_POS (0) #define SCD_QUEUE_CTX_REG2_WIN_SIZE_MSK (0x0000007F) #define SCD_QUEUE_CTX_REG2_FRAME_LIMIT_POS (16) #define SCD_QUEUE_CTX_REG2_FRAME_LIMIT_MSK (0x007F0000) /* Context Data */ #define SCD_CONTEXT_MEM_LOWER_BOUND (SCD_MEM_LOWER_BOUND + 0x600) #define SCD_CONTEXT_MEM_UPPER_BOUND (SCD_MEM_LOWER_BOUND + 0x6A0) /* Tx status */ #define SCD_TX_STTS_MEM_LOWER_BOUND (SCD_MEM_LOWER_BOUND + 0x6A0) #define SCD_TX_STTS_MEM_UPPER_BOUND (SCD_MEM_LOWER_BOUND + 0x7E0) /* Translation Data */ #define SCD_TRANS_TBL_MEM_LOWER_BOUND (SCD_MEM_LOWER_BOUND + 0x7E0) #define SCD_TRANS_TBL_MEM_UPPER_BOUND (SCD_MEM_LOWER_BOUND + 0x808) #define SCD_CONTEXT_QUEUE_OFFSET(x)\ (SCD_CONTEXT_MEM_LOWER_BOUND + ((x) * 8)) #define SCD_TX_STTS_QUEUE_OFFSET(x)\ (SCD_TX_STTS_MEM_LOWER_BOUND + ((x) * 16)) #define SCD_TRANS_TBL_OFFSET_QUEUE(x) \ ((SCD_TRANS_TBL_MEM_LOWER_BOUND + ((x) * 2)) & 0xfffc) #define SCD_BASE (PRPH_BASE + 0xa02c00) #define SCD_SRAM_BASE_ADDR (SCD_BASE + 0x0) #define SCD_DRAM_BASE_ADDR (SCD_BASE + 0x8) #define SCD_AIT (SCD_BASE + 0x0c) #define SCD_TXFACT (SCD_BASE + 0x10) #define SCD_ACTIVE (SCD_BASE + 0x14) #define SCD_QUEUECHAIN_SEL (SCD_BASE + 0xe8) #define SCD_CHAINEXT_EN (SCD_BASE + 0x244) #define SCD_AGGR_SEL (SCD_BASE + 0x248) #define SCD_INTERRUPT_MASK (SCD_BASE + 0x108) static inline unsigned int SCD_QUEUE_WRPTR(unsigned int chnl) { if (chnl < 20) return SCD_BASE + 0x18 + chnl * 4;
