Unlike Tx, there is only one Rx * queue, and only one Rx DMA/FIFO channel. Also unlike Tx, which can * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1 * mapping between RBDs and RBs. * * Driver must allocate host DRAM memory for the following, and set the * physical address of each into SP registers: * * 1) Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256 * entries (although any power of 2, up to 4096, is selectable by driver). * Each entry (1 dword) points to a receive buffer (RB) of consistent size * (typically 4K, although 8K or 16K are also selectable by driver). * Driver sets up RB size and number of RBDs in the CB via Rx config * register FH_MEM_RCSR_CHNL0_CONFIG_REG. * * Bit fields within one RBD: * 27-0: Receive Buffer physical address bits [35:8], 256-byte aligned. * * Driver sets physical address [35:8] of base of RBD circular buffer * into FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0]. * * 2) Rx status buffer, 8 bytes, in which SP indicates which Rx Buffers * (RBs) have been filled, via a "write pointer", actually the index of * the RB's corresponding RBD within the circular buffer. Driver sets * physical address [35:4] into FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0]. * * Bit fields in lower dword of Rx status buffer (upper dword not used * by driver; see struct iwh_shared, val0): * 31-12: Not used by driver * 11- 0: Index of last filled Rx buffer descriptor * (SP writes, driver reads this value) * * As the driver prepares Receive Buffers (RBs) for SP to fill, driver must * enter pointers to these RBs into contiguous RBD circular buffer entries, * and update the SP's "write" index register, FH_RSCSR_CHNL0_RBDCB_WPTR_REG. * * This "write" index corresponds to the *next* RBD that the driver will make * available, i.e. one RBD past the the tail of the ready-to-fill RBDs within * the circular buffer. This value should initially be 0 (before preparing any * RBs), should be 8 after preparing the first 8 RBs (for example), and must * wrap back to 0 at the end of the circular buffer (but don't wrap before * "read" index has advanced past 1! See below). * NOTE: SP EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8. * * As the SP fills RBs (referenced from contiguous RBDs within the circular * buffer), it updates the Rx status buffer in DRAM, 2) described above, * to tell the driver the index of the latest filled RBD. The driver must * read this "read" index from DRAM after receiving an Rx interrupt from SP. * * The driver must also internally keep track of a third index, which is the * next RBD to process. When receiving an Rx interrupt, driver should process * all filled but unprocessed RBs up to, but not including, the RB * corresponding to the "read" index. For example, if "read" index becomes "1", * driver may process the RB pointed to by RBD 0. Depending on volume of * traffic, there may be many RBs to process. * * If read index == write index, SP thinks there is no room to put new data. * Due to this, the maximum number of filled RBs is 255, instead of 256. To * be safe, make sure that there is a gap of at least 2 RBDs between "write" * and "read" indexes; that is, make sure that there are no more than 254 * buffers waiting to be filled. */ #define

host DRAM. It steers each frame's Tx command (which contains the frame * data) through 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 channels have dedicated purposes. For SP, and are used as follows: * BMC TODO: CONFIRM channel assignments, esp for 0/1 * * 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 -- Commands (e.g. RXON, etc.) * 5 -- HCCA short frames * 6 -- HCCA long frames * 7 -- not used by driver (device-internal only) * * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6. * In addition, driver can map queues 7-15 to Tx DMA/FIFO channels 0-3 to * support 11n aggregation via EDCA DMA channels. BMC confirm. * * 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 * (struct iwh_sched_queue_byte_cnt_tbl) 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) 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 4956 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 following (especially for queue #4, the command queue, otherwise * the driver can't issue commands!): * * 1) SP's scheduler data base area in SRAM: * a) Read SRAM address of data base area from SCD_SRAM_BASE_ADDR * b) Clear and Init SCD_CONTEXT_DATA_OFFSET area (size 128 bytes) * c) Clear SCD_TX_STTS_BITMAP_OFFSET area (size 256 bytes) * d) Clear (BMC and init?)
