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 iwl4965_shared, val0): - * 31-12: Not used by driver - * 11- 0: Index of last filled Rx buffer descriptor - * (4965 writes, driver reads this value) - * - * As the driver prepares Receive Buffers (RBs) for 4965 to fill, driver must - * enter pointers to these RBs into contiguous RBD circular buffer entries, - * and update the 4965'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 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: 4965 EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8. - * - * As the 4965 fills RBs (referenced from contiguous RBDs within the circular - * buffer), it updates the Rx status buffer in host 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 4965. - * - * 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, 4965 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 FH_MEM_RSCSR_LOWER_BOUND (FH_MEM_LOWER_BOUND + 0xBC0) -#define FH_MEM_RSCSR_UPPER_BOUND (FH_MEM_LOWER_BOUND + 0xC00) -#define FH_MEM_RSCSR_CHNL0 (FH_MEM_RSCSR_LOWER_BOUND) - -/** - * Physical base address of 8-byte Rx Status buffer. - * Bit fields: - * 31-0: Rx status buffer physical base address [35:4], must 16-byte aligned. - */ -#define FH_RSCSR_CHNL0_STTS_WPTR_REG (FH_MEM_RSCSR_CHNL0) - -/** - * Physical base address of Rx Buffer Descriptor Circular Buffer. - * Bit fields: - * 27-0: RBD CD physical base address [35:8], must be 256-byte aligned. - */ -#define FH_RSCSR_CHNL0_RBDCB_BASE_REG (FH_MEM_RSCSR_CHNL0 + 0x004) - -/** - * Rx write pointer (index, really!). - * Bit fields: - * 11-0: Index of driver's most recent prepared-to-be-filled RBD, + 1. - * NOTE: For 256-entry circular buffer, use only bits [7:0]. - */ -#define FH_RSCSR_CHNL0_RBDCB_WPTR_REG (FH_MEM_RSCSR_CHNL0 + 0x008) -#define FH_RSCSR_CHNL0_WPTR (FH_RSCSR_CHNL0_RBDCB_WPTR_REG) - - -/** - * Rx Config/Status Registers (RCSR) - * Rx Config Reg for channel 0 (only channel used) - * - * Driver must initialize FH_MEM_RCSR_CHNL0_CONFIG_REG as follows for - * normal operation (see bit fields). - * - * Clearing FH_MEM_RCSR_CHNL0_CONFIG_REG to 0 turns off Rx DMA. - * Driver should poll FH_MEM_RSSR_RX_STATUS_REG for - * FH_RSSR_CHNL0_RX_STATUS_CHNL_IDLE (bit 24) before continuing. - * - * Bit fields: - * 31-30: Rx DMA channel enable: '00' off/pause, '01' pause at end of frame, - * '10' operate normally - * 29-24: reserved - * 23-20: # RBDs in circular buffer = 2^value;

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 4965, they are used as follows: - * - * 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. - * - * 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.
