The host driver * indicates DRAM locations and sizes for instruction and data images via the * four BSM_DRAM_* registers. Once the bootstrap program loads the new program, * the new program starts automatically. * * The uCode used for open-source drivers includes two programs: * * 1) Initialization -- performs hardware calibration and sets up some * internal data, then notifies host via "initialize alive" notification * (struct iwl_init_alive_resp) that it has completed all of its work. * After signal from host, it then loads and starts the runtime program. * The initialization program must be used when initially setting up the * NIC after loading the driver. * * 2) Runtime/Protocol -- performs all normal runtime operations. This * notifies host via "alive" notification (struct iwl_alive_resp) that it * is ready to be used. * * When initializing the NIC, the host driver does the following procedure: * * 1) Load bootstrap program (instructions only, no data image for bootstrap) * into bootstrap memory. Use dword writes starting at BSM_SRAM_LOWER_BOUND * * 2) Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction * images in host DRAM. * * 3) Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked: * BSM_WR_MEM_SRC_REG = 0 * BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND * BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image * * 4) Load bootstrap into instruction SRAM: * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START * * 5) Wait for load completion: * Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0 * * 6) Enable future boot loads whenever NIC's power management triggers it: * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN * * 7) Start the NIC by removing all reset bits: * CSR_RESET = 0 * * The bootstrap uCode (already in instruction SRAM) loads initialization * uCode. Initialization uCode performs data initialization, sends * "initialize alive" notification to host, and waits for a signal from * host to load runtime code. * * 4) Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction * images in host DRAM. The last register loaded must be the instruction * bytecount register ("1" in MSbit tells initialization uCode to load * the runtime uCode): * BSM_DRAM_INST_BYTECOUNT_REG = bytecount | BSM_DRAM_INST_LOAD * * 5) Wait for "alive" notification, then issue normal runtime commands. * * Data caching during power-downs: * * Just before the embedded controller powers down (e.g for automatic * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA) * a current snapshot of the embedded processor's data SRAM into host DRAM. * This caches the data while the embedded processor's memory is powered down. * Location and size are controlled by BSM_DRAM_DATA_* registers. * * NOTE: Instruction SRAM does not need to be saved, since that doesn't * change during operation; the original image (from uCode distribution * file) can be used for reload. * * When powering back up, the BSM loads the bootstrap program. Bootstrap looks * at the BSM_DRAM_* registers, which now point to the runtime instruction * image and the cached (modified) runtime data (*not* the initialization * uCode). Bootstrap reloads these runtime images into SRAM, and restarts the * uCode from where it left off before the power-down. * * NOTE: Initialization uCode does *not* run as part of the save/restore * procedure. * * This save/restore method is mostly for autonomous power management during * normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and * RFKILL should use complete restarts (with total re-initialization) of uCode, * allowing total shutdown (including BSM memory). * * Note that, during normal operation, the host DRAM that held the initial * startup data for the runtime code is now being used as a backup data cache * for modified data! If you need to completely re-initialize the NIC, make * sure that you use the runtime data image from the uCode distribution file, * not the modified/saved runtime data. You may want to store a separate * "clean" runtime data image in DRAM to avoid disk reads of distribution file. */ /* BSM bit fields */ #define BSM_WR_CTRL_REG_BIT_START (0x80000000) /* start boot load now */ #define BSM_WR_CTRL_REG_BIT_START_EN (0x40000000) /* enable boot after pwrup*/ #define BSM_DRAM_INST_LOAD (0x80000000) /* start program load now */ /* BSM addresses */ #define BSM_BASE (PRPH_BASE + 0x3400) #define BSM_END (PRPH_BASE + 0x3800) #define BSM_WR_CTRL_REG (BSM_BASE + 0x000) /* ctl and status */ #define BSM_WR_MEM_SRC_REG (BSM_BASE + 0x004) /* source in BSM mem */ #define BSM_WR_MEM_DST_REG (BSM_BASE + 0x008) /* dest in SRAM mem */ #define BSM_WR_DWCOUNT_REG (BSM_BASE + 0x00C) /* bytes */ #define BSM_WR_STATUS_REG (BSM_BASE + 0x010) /* bit 0: 1 == done */ /* * Pointers and size regs for bootstrap load and data SRAM save/restore. * NOTE: 3945 pointers use bits 31:0 of DRAM address. * 4965 pointers use bits 35:4 of DRAM address. */ #define BSM_DRAM_INST_PTR_REG (BSM_BASE + 0x090) #define BSM_DRAM_INST_BYTECOUNT_REG (BSM_BASE + 0x094) #define BSM_DRAM_DATA_PTR_REG (BSM_BASE + 0x098) #define BSM_DRAM_DATA_BYTECOUNT_REG (BSM_BASE + 0x09C) /* * BSM special memory, stays powered on during power-save sleeps. * Read/write, address range from LOWER_BOUND to (LOWER_BOUND + SIZE -1) */ #define BSM_SRAM_LOWER_BOUND (PRPH_BASE + 0x3800) #define BSM_SRAM_SIZE (1024) /* bytes */ /* 3945 Tx scheduler registers */ #define ALM_SCD_BASE (PRPH_BASE + 0x2E00) #define ALM_SCD_MODE_REG (ALM_SCD_BASE + 0x000) #define ALM_SCD_ARASTAT_REG (ALM_SCD_BASE + 0x004) #define ALM_SCD_TXFACT_REG (ALM_SCD_BASE + 0x010) #define ALM_SCD_TXF4MF_REG (ALM_SCD_BASE + 0x014) #define ALM_SCD_TXF5MF_REG (ALM_SCD_BASE + 0x020) #define ALM_SCD_SBYP_MODE_1_REG (ALM_SCD_BASE + 0x02C) #define ALM_SCD_SBYP_MODE_2_REG (ALM_SCD_BASE + 0x030) /** * Tx Scheduler * * The Tx Scheduler selects the next frame to be transmitted, chosing 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 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. 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 iwl4965_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 scheduler (especially for queue #4, 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. * Driver should use SCD_WIN_SIZE and SCD_FRAME_LIMIT values to initialize * IWL49_SCD_CONTEXT_QUEUE_OFFSET(x) values. */ #define SCD_WIN_SIZE 64 #define SCD_FRAME_LIMIT 64 /* SCD registers are internal, must be accessed via HBUS_TARG_PRPH regs */ #define IWL49_SCD_START_OFFSET 0xa02c00 /* * 4965 tells driver SRAM address for internal scheduler structs via this reg. * Value is valid only after "Alive" response from uCode. */ #define IWL49_SCD_SRAM_BASE_ADDR (IWL49_SCD_START_OFFSET + 0x0) /* * Driver may need to update queue-empty bits after changing queue's * write and read pointers (indexes) during (re-)initialization (i.e. when * scheduler is not tracking what's happening). * Bit fields: * 31-16: Write mask -- 1: update empty bit, 0: don't change empty bit * 15-00: Empty state, one for each queue -- 1: empty, 0: non-empty * NOTE: This register is not used by Linux driver. */ #define IWL49_SCD_EMPTY_BITS (IWL49_SCD_START_OFFSET + 0x4) /* * Physical base address of array of byte count (BC) circular buffers (CBs). * Each Tx queue has a BC CB in host DRAM to support Scheduler-ACK mode. * This register points to BC CB for queue 0, must be on 1024-byte boundary. * Others are spaced by 1024 bytes. * Each BC CB is 2 bytes * (256 + 64) = 740 bytes, followed by 384 bytes pad. * (Index into a queue's BC CB) = (index into queue's TFD CB) = (SSN & 0xff). * Bit fields: * 25-00: Byte Count CB physical address [35:10], must be 1024-byte aligned. */ #define IWL49_SCD_DRAM_BASE_ADDR (IWL49_SCD_START_OFFSET + 0x10) /* * Enables any/all Tx DMA/FIFO channels. * Scheduler generates requests for only the active channels. * Set this to 0xff to enable all 8 channels (normal usage). * Bit fields: * 7- 0: Enable (1), disable (0), one bit for each channel 0-7 */ #define IWL49_SCD_TXFACT (IWL49_SCD_START_OFFSET + 0x1c) /* * Queue (x) Write Pointers (indexes, really!), one for each Tx queue. * Initialized and updated by driver as new TFDs are added to queue. * NOTE: If using Block Ack, index must correspond to frame's * Start Sequence Number; index = (SSN & 0xff) * NOTE: Alternative to HBUS_TARG_WRPTR, which is what Linux driver uses? */ #define IWL49_SCD_QUEUE_WRPTR(x) (IWL49_SCD_START_OFFSET + 0x24 + (x) * 4) /* * Queue (x) Read Pointers (indexes, really!), one for each Tx queue. * For FIFO mode, index indicates next frame to transmit. * For Scheduler-ACK mode, index indicates first frame in Tx window. * Initialized by driver, updated by scheduler. */ #define IWL49_SCD_QUEUE_RDPTR(x) (IWL49_SCD_START_OFFSET + 0x64 + (x) * 4) /* * Select which queues work in chain mode (1) vs. not (0). * Use chain mode to build chains of aggregated frames. * Bit fields: * 31-16: Reserved * 15-00: Mode, one bit for each queue -- 1: Chain mode, 0: one-at-a-time * NOTE: If driver sets up queue for chain mode, it should be also set up * Scheduler-ACK mode as well, via SCD_QUEUE_STATUS_BITS(x). */ #define IWL49_SCD_QUEUECHAIN_SEL (IWL49_SCD_START_OFFSET + 0xd0) /* * Select which queues interrupt driver when scheduler increments * a queue's read pointer (index). * Bit fields: * 31-16: Reserved * 15-00: Interrupt enable, one bit for each queue -- 1: enabled, 0: disabled * NOTE: This functionality is apparently a no-op; driver relies on interrupts * from Rx queue to read Tx command responses and update Tx queues. */ #define IWL49_SCD_INTERRUPT_MASK (IWL49_SCD_START_OFFSET + 0xe4) /* * Queue search status registers.
