Of course, other - * procedures are possible, and may work better for particular environments. - * - * - * FILLING THE RATE TABLE - * - * Given a particular initial rate and mode, as determined by the rate - * scaling algorithm described below, the Linux driver uses the following - * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the - * Link Quality command: - * - * - * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: - * a) Use this same initial rate for first 3 entries. - * b) Find next lower available rate using same mode (SISO or MIMO), - * use for next 3 entries. If no lower rate available, switch to - * legacy mode (no HT40 channel, no MIMO, no short guard interval). - * c) If using MIMO, set command's mimo_delimiter to number of entries - * using MIMO (3 or 6). - * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, - * no MIMO, no short guard interval), at the next lower bit rate - * (e.g. if second HT bit rate was 54, try 48 legacy), and follow - * legacy procedure for remaining table entries. - * - * 2) If using legacy initial rate: - * a) Use the initial rate for only one entry. - * b) For each following entry, reduce the rate to next lower available - * rate, until reaching the lowest available rate. - * c) When reducing rate, also switch antenna selection. - * d) Once lowest available rate is reached, repeat this rate until - * rate table is filled (16 entries), switching antenna each entry. - * - * - * ACCUMULATING HISTORY - * - * The rate scaling algorithm for agn devices, as implemented in Linux driver, - * uses two sets of frame Tx success history: One for the current/active - * modulation mode, and one for a speculative/search mode that is being - * attempted. If the speculative mode turns out to be more effective (i.e. - * actual transfer rate is better), then the driver continues to use the - * speculative mode as the new current active mode. - * - * Each history set contains, separately for each possible rate, data for a - * sliding window of the 62 most recent tx attempts at that rate. The data - * includes a shifting bitmap of success(1)/failure(0), and sums of successful - * and attempted frames, from which the driver can additionally calculate a - * success ratio (success / attempted) and number of failures - * (attempted - success), and control the size of the window (attempted). - * The driver uses the bit map to remove successes from the success sum, as - * the oldest tx attempts fall out of the window. - * - * When the agn device makes multiple tx attempts for a given frame, each - * attempt might be at a different rate, and have different modulation - * characteristics (e.g. antenna, fat channel, short guard interval), as set - * up in the rate scaling table in the Link Quality command. The driver must - * determine which rate table entry was used for each tx attempt, to determine - * which rate-specific history to update, and record only those attempts that - * match the modulation characteristics of the history set. - * - * When using block-ack (aggregation), all frames are transmitted at the same - * rate, since there is no per-attempt acknowledgment from the destination - * station. The Tx response struct iwl_tx_resp indicates the Tx rate in - * rate_n_flags field. After receiving a block-ack, the driver can update - * history for the entire block all at once. - * - * - * FINDING BEST STARTING RATE: - * - * When working with a selected initial modulation mode (see below), the - * driver attempts to find a best initial rate. The initial rate is the - * first entry in the Link Quality command's rate table. - * - * 1) Calculate actual throughput (success ratio * expected throughput, see - * table below) for current initial rate. Do this only if enough frames - * have been attempted to make the value meaningful: at least 6 failed - * tx attempts, or at least 8 successes. If not enough, don't try rate - * scaling yet. - * - * 2) Find available rates adjacent to current initial rate. Available means: - * a) supported by hardware && - * b) supported by association && - * c) within any constraints selected by user - * - * 3) Gather measured throughputs for adjacent rates. These might not have - * enough history to calculate a throughput. That's okay, we might try - * using one of them anyway! - * - * 4) Try decreasing rate if, for current rate: - * a) success ratio is < 15% || - * b) lower adjacent rate has better measured throughput || - * c) higher adjacent rate has worse throughput, and lower is unmeasured - * - * As a sanity check, if decrease was determined above, leave rate - * unchanged if: - * a) lower rate unavailable - * b) success ratio at current rate > 85% (very good) - * c) current measured throughput is better than expected throughput - * of lower rate (under perfect 100% tx conditions, see table below) - * - * 5) Try increasing rate if, for current rate: - * a) success ratio is < 15% || - * b) both adjacent rates' throughputs are unmeasured (try it!) || - * b) higher adjacent rate has better measured throughput || - * c) lower adjacent rate has worse throughput, and higher is unmeasured - * - * As a sanity check, if increase was determined above, leave rate - * unchanged if: - * a) success ratio at current rate < 70%. This is not particularly - * good performance; higher rate is sure to have poorer success. - * - * 6) Re-evaluate the rate after each tx frame. If working with block- - * acknowledge, history and statistics may be calculated for the entire - * block (including prior history that fits within the history windows), - * before re-evaluation. - * - * FINDING BEST STARTING MODULATION MODE: - * - * After working with a modulation mode for a "while" (and doing rate scaling), - * the driver searches for a new initial mode in an attempt to improve - * throughput. The "while" is measured by numbers of attempted frames: - * - * For legacy mode, search for new mode after: - * 480 successful frames, or 160 failed frames - * For high-throughput modes (SISO or MIMO), search for new mode after: - * 4500 successful frames, or 400 failed frames - * - * Mode switch possibilities are (3 for each mode): - * - * For legacy: - * Change antenna, try SISO (if HT association), try MIMO (if HT association) - * For SISO: - * Change antenna, try MIMO, try shortened guard interval (SGI) - * For MIMO: - * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) - * - * When trying a new mode, use the same bit rate as the old/current mode when - * trying antenna switches and shortened guard interval. When switching to - * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate - * for which the expected throughput (under perfect conditions) is about the - * same or slightly better than the actual measured throughput delivered by - * the old/current mode. - * - * Actual throughput can be estimated by multiplying the expected throughput - * by the success ratio (successful / attempted tx frames). Frame size is - * not considered in this calculation; it assumes that frame size will average - * out to be fairly consistent over several samples. The following are - * metric values for expected throughput assuming 100% success ratio. - * Only G band has support for CCK rates: - * - * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 - * - * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 - * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 - * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 - * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 - * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 - * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 - * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 - * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 - * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 - * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 - * - * After the new mode has been tried for a short while (minimum of 6 failed - * frames or 8 successful frames), compare success ratio and actual throughput - * estimate of the new mode with the old.

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) -#define SCD_GP_CTRL_ENABLE_31_QUEUES BIT(0) -#define SCD_GP_CTRL_AUTO_ACTIVE_MODE BIT(18) - -/* 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) -#define SCD_GP_CTRL (SCD_BASE + 0x1a8) -#define SCD_EN_CTRL (SCD_BASE + 0x254) - -/*********************** END TX SCHEDULER *************************************/ - -/* tcp checksum offload */ -#define RX_EN_CSUM (0x00a00d88) - -/* Oscillator clock */ -#define OSC_CLK (0xa04068) -#define OSC_CLK_FORCE_CONTROL (0x8) - -#define FH_UCODE_LOAD_STATUS (0x1AF0) -#define CSR_UCODE_LOAD_STATUS_ADDR (0x1E70) -enum secure_load_status_reg { - LMPM_CPU_UCODE_LOADING_STARTED = 0x00000001, - LMPM_CPU_HDRS_LOADING_COMPLETED = 0x00000003, - LMPM_CPU_UCODE_LOADING_COMPLETED = 0x00000007, - LMPM_CPU_STATUS_NUM_OF_LAST_COMPLETED = 0x000000F8, - LMPM_CPU_STATUS_NUM_OF_LAST_LOADED_BLOCK = 0x0000FF00, -};

The driver - * keeps the fw's station table up to date with the ADD_STA command. Stations - * can be removed by the REMOVE_STA command. - * - * All the data related to a station is held in the structure %iwl_mvm_sta - * which is embed in the mac80211's %ieee80211_sta (in the drv_priv) area. - * This data includes the index of the station in the fw, per tid information - * (sequence numbers, Block-ack state machine, etc...). The stations are - * created and deleted by the %sta_state callback from %ieee80211_ops. - * - * The driver holds a map: %fw_id_to_mac_id that allows to fetch a - * %ieee80211_sta (and the %iwl_mvm_sta embedded into it) based on a fw - * station index. That way, the driver is able to get the tid related data in - * O(1) in time sensitive paths (Tx / Tx response / BA notification). These - * paths are triggered by the fw, and the driver needs to get a pointer to the - * %ieee80211 structure.

The next paragraph explains - * the locking of a single stations, the next ones relates to the station - * table. - * - * The station holds the sequence number per tid. So this data needs to be - * accessed in the Tx path (which is softIRQ). It also holds the Block-Ack - * information (the state machine / and the logic that checks if the queues - * were drained), so it also needs to be accessible from the Tx response flow. - * In short, the station needs to be access from sleepable context as well as - * from tasklets, so the station itself needs a spinlock. - * - * The writers of %fw_id_to_mac_id map are serialized by the global mutex of - * the mvm op_mode. This is possible since %sta_state can sleep. - * The pointers in this map are RCU protected, hence we won't replace the - * station while we have Tx / Tx response / BA notification running. - * - * If a station is deleted while it still has packets in its A-MPDU queues, - * then the reclaim flow will notice that there is no station in the map for - * sta_id and it will dump the responses. - */ - -/** - * DOC: station table - internal stations - * - * The FW needs a few internal stations that are not reflected in - * mac80211, such as broadcast station in AP / GO mode, or AUX sta for - * scanning and P2P device (during the GO negotiation). - * For these kind of stations we have %iwl_mvm_int_sta struct which holds the - * data relevant for them from both %iwl_mvm_sta and %ieee80211_sta. - * Usually the data for these stations is static, so no locking is required, - * and no TID data as this is also not needed. - * One thing to note, is that these stations have an ID in the fw, but not - * in mac80211. In order to "reserve" them a sta_id in %fw_id_to_mac_id - * we fill ERR_PTR(EINVAL) in this mapping and all other dereferencing of - * pointers from this mapping need to check that the value is not error - * or NULL. - * - * Currently there is only one auxiliary station for scanning, initialized - * on init. - */ - -/** - * DOC: station table - AP Station in STA mode - * - * %iwl_mvm_vif includes the index of the AP station in the fw's STA table: - * %ap_sta_id. To get the point to the corresponding %ieee80211_sta, - * &fw_id_to_mac_id can be used. Due to the way the fw works, we must not remove - * the AP station from the fw before setting the MAC context as unassociated. - * Hence, %fw_id_to_mac_id[%ap_sta_id] will be NULLed when the AP station is - * removed by mac80211, but the station won't be removed in the fw until the - * VIF is set as unassociated. Then, %ap_sta_id will be invalidated. - */ - -/** - * DOC: station table - Drain vs. Flush - * - * Flush means that all the frames in the SCD queue are dumped regardless the - * station to which they were sent. We do that when we disassociate and before - * we remove the STA of the AP. The flush can be done synchronously against the - * fw. - * Drain means that the fw will drop all the frames sent to a specific station. - * This is useful when a client (if we are IBSS / GO or AP) disassociates. In - * that case, we need to drain all the frames for that client from the AC queues - * that are shared with the other clients. Only then, we can remove the STA in - * the fw. In order to do so, we track the non-AMPDU packets for each station. - * If mac80211 removes a STA and if it still has non-AMPDU packets pending in - * the queues, we mark this station as %EBUSY in %fw_id_to_mac_id, and drop all - * the frames for this STA (%iwl_mvm_rm_sta). When the last frame is dropped - * (we know about it with its Tx response), we remove the station in fw and set - * it as %NULL in %fw_id_to_mac_id: this is the purpose of - * %iwl_mvm_sta_drained_wk. - */ - -/** - * DOC: station table - fw restart - * - * When the fw asserts, or we have any other issue that requires to reset the - * driver, we require mac80211 to reconfigure the driver. Since the private - * data of the stations is embed in mac80211's %ieee80211_sta, that data will - * not be zeroed and needs to be reinitialized manually. - * %IWL_MVM_STATUS_IN_HW_RESTART is set during restart and that will hint us - * that we must not allocate a new sta_id but reuse the previous one. This - * means that the stations being re-added after the reset will have the same - * place in the fw as before the reset. We do need to zero the %fw_id_to_mac_id - * map, since the stations aren't in the fw any more. Internal stations that - * are not added by mac80211 will be re-added in the init flow that is called - * after the restart: mac80211 call's %iwl_mvm_mac_start which calls to - * %iwl_mvm_up. - */ - -/** - * DOC: AP mode - PS - * - * When a station is asleep, the fw will set it as "asleep". All frames on - * shared queues (i.e. non-aggregation queues) to that station will be dropped - * by the fw (%TX_STATUS_FAIL_DEST_PS failure code). - * - * AMPDUs are in a separate queue that is stopped by the fw. We just need to - * let mac80211 know when there are frames in these queues so that it can - * properly handle trigger frames. - * - * When a trigger frame is received, mac80211 tells the driver to send frames - * from the AMPDU queues or sends frames to non-aggregation queues itself, - * depending on which ACs are delivery-enabled and what TID has frames to - * transmit. Note that mac80211 has all the knowledge since all the non-agg - * frames are buffered / filtered, and the driver tells mac80211 about agg - * frames). The driver needs to tell the fw to let frames out even if the - * station is asleep. This is done by %iwl_mvm_sta_modify_sleep_tx_count. - * - * When we receive a frame from that station with PM bit unset, the driver - * needs to let the fw know that this station isn't asleep any more. This is - * done by %iwl_mvm_sta_modify_ps_wake in response to mac80211 signaling the - * station's wakeup. - * - * For a GO, the Service Period might be cut short due to an absence period - * of the GO. In this (and all other cases) the firmware notifies us with the - * EOSP_NOTIFICATION, and we notify mac80211 of that.

These get - * used not only for Rx frames, but for any command response or notification - * from the NIC. The driver and NIC manage the Rx buffers by means - * of indexes into the circular buffer. - * - * Rx Queue Indexes - * The host/firmware share two index registers for managing the Rx buffers. - * - * The READ index maps to the first position that the firmware may be writing - * to -- the driver can read up to (but not including) this position and get - * good data. - * The READ index is managed by the firmware once the card is enabled. - * - * The WRITE index maps to the last position the driver has read from -- the - * position preceding WRITE is the last slot the firmware can place a packet. - * - * The queue is empty (no good data) if WRITE = READ - 1, and is full if - * WRITE = READ. - * - * During initialization, the host sets up the READ queue position to the first - * INDEX position, and WRITE to the last (READ - 1 wrapped) - * - * When the firmware places a packet in a buffer, it will advance the READ index - * and fire the RX interrupt. The driver can then query the READ index and - * process as many packets as possible, moving the WRITE index forward as it - * resets the Rx queue buffers with new memory. - * - * The management in the driver is as follows: - * + A list of pre-allocated RBDs is stored in iwl->rxq->rx_free. - * When the interrupt handler is called, the request is processed. - * The page is either stolen - transferred to the upper layer - * or reused - added immediately to the iwl->rxq->rx_free list. - * + When the page is stolen - the driver updates the matching queue's used - * count, detaches the RBD and transfers it to the queue used list. - * When there are two used RBDs - they are transferred to the allocator empty - * list. Work is then scheduled for the allocator to start allocating - * eight buffers. - * When there are another 6 used RBDs - they are transferred to the allocator - * empty list and the driver tries to claim the pre-allocated buffers and - * add them to iwl->rxq->rx_free. If it fails - it continues to claim them - * until ready. - * When there are 8+ buffers in the free list - either from allocation or from - * 8 reused unstolen pages - restock is called to update the FW and indexes. - * + In order to make sure the allocator always has RBDs to use for allocation - * the allocator has initial pool in the size of num_queues*(8-2) - the - * maximum missing RBDs per allocation request (request posted with 2 - * empty RBDs, there is no guarantee when the other 6 RBDs are supplied). - * The queues supplies the recycle of the rest of the RBDs. - * + A received packet is processed and handed to the kernel network stack, - * detached from the iwl->rxq. The driver 'processed' index is updated. - * + If there are no allocated buffers in iwl->rxq->rx_free, - * the READ INDEX is not incremented and iwl->status(RX_STALLED) is set. - * If there were enough free buffers and RX_STALLED is set it is cleared. - * - * - * Driver sequence: - * - * iwl_rxq_alloc() Allocates rx_free - * iwl_pcie_rx_replenish() Replenishes rx_free list from rx_used, and calls - * iwl_pcie_rxq_restock. - * Used only during initialization. - * iwl_pcie_rxq_restock() Moves available buffers from rx_free into Rx - * queue, updates firmware pointers, and updates - * the WRITE index. - * iwl_pcie_rx_allocator() Background work for allocating pages. - * - * -- enable interrupts -- - * ISR - iwl_rx() Detach iwl_rx_mem_buffers from pool up to the - * READ INDEX, detaching the SKB from the pool. - * Moves the packet buffer from queue to rx_used. - * Posts and claims requests to the allocator. - * Calls iwl_pcie_rxq_restock to refill any empty - * slots. - * - * RBD life-cycle: - * - * Init: - * rxq.pool -> rxq.rx_used -> rxq.rx_free -> rxq.queue - * - * Regular Receive interrupt: - * Page Stolen: - * rxq.queue -> rxq.rx_used -> allocator.rbd_empty -> - * allocator.rbd_allocated -> rxq.rx_free -> rxq.queue - * Page not Stolen: - * rxq.queue -> rxq.rx_free -> rxq.queue - * ... - * - */ - -/* - * iwl_rxq_space - Return number of free slots available in queue. - */ -static int iwl_rxq_space(const struct iwl_rxq *rxq) -{ - /* Make sure RX_QUEUE_SIZE is a power of 2 */ - BUILD_BUG_ON(RX_QUEUE_SIZE & (RX_QUEUE_SIZE - 1)); - - /* - * There can be up to (RX_QUEUE_SIZE - 1) free slots, to avoid ambiguity - * between empty and completely full queues. - * The following is equivalent to modulo by RX_QUEUE_SIZE and is well - * defined for negative dividends. - */ - return (rxq->read - rxq->write - 1) & (RX_QUEUE_SIZE - 1); -} - -/* - * iwl_dma_addr2rbd_ptr - convert a DMA address to a uCode read buffer ptr - */ -static inline __le32 iwl_pcie_dma_addr2rbd_ptr(dma_addr_t dma_addr) -{ - return cpu_to_le32((u32)(dma_addr >> 8)); -} - -/* - * iwl_pcie_rx_stop - stops the Rx DMA - */ -int iwl_pcie_rx_stop(struct iwl_trans *trans) -{ - iwl_write_direct32(trans, FH_MEM_RCSR_CHNL0_CONFIG_REG, 0); - return iwl_poll_direct_bit(trans, FH_MEM_RSSR_RX_STATUS_REG, - FH_RSSR_CHNL0_RX_STATUS_CHNL_IDLE, 1000); -} - -/* - * iwl_pcie_rxq_inc_wr_ptr - Update the write pointer for the RX queue - */ -static void iwl_pcie_rxq_inc_wr_ptr(struct iwl_trans *trans) -{ - struct iwl_trans_pcie *trans_pcie = IWL_TRANS_GET_PCIE_TRANS(trans); - struct iwl_rxq *rxq = &trans_pcie->rxq; - u32 reg; - - lockdep_assert_held(&rxq->lock); - - /* - * explicitly wake up the NIC if: - * 1. shadow registers aren't enabled - * 2. there is a chance that the NIC is asleep - */ - if (!trans->cfg->base_params->shadow_reg_enable && - test_bit(STATUS_TPOWER_PMI, &trans->status)) { - reg = iwl_read32(trans, CSR_UCODE_DRV_GP1); - - if (reg & CSR_UCODE_DRV_GP1_BIT_MAC_SLEEP) { - IWL_DEBUG_INFO(trans, "Rx queue requesting wakeup, GP1 = 0x%x\n", - reg); - iwl_set_bit(trans, CSR_GP_CNTRL, - CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ); - rxq->need_update = true; - return; - } - } - - rxq->write_actual = round_down(rxq->write, 8); - iwl_write32(trans, FH_RSCSR_CHNL0_WPTR, rxq->write_actual); -} - -static void iwl_pcie_rxq_check_wrptr(struct iwl_trans *trans) -{ - struct iwl_trans_pcie *trans_pcie = IWL_TRANS_GET_PCIE_TRANS(trans); - struct iwl_rxq *rxq = &trans_pcie->rxq; - - spin_lock(&rxq->lock); - - if (!rxq->need_update) - goto exit_unlock; - - iwl_pcie_rxq_inc_wr_ptr(trans); - rxq->need_update = false; - - exit_unlock: - spin_unlock(&rxq->lock); -} - -/* - * iwl_pcie_rxq_restock - refill RX queue from pre-allocated pool - * - * If there are slots in the RX queue that need to be restocked, - * and we have free pre-allocated buffers, fill the ranks as much - * as we can, pulling from rx_free. - * - * This moves the 'write' index forward to catch up with 'processed', and - * also updates the memory address in the firmware to reference the new - * target buffer. - */ -static void iwl_pcie_rxq_restock(struct iwl_trans *trans) -{ - struct iwl_trans_pcie *trans_pcie = IWL_TRANS_GET_PCIE_TRANS(trans); - struct iwl_rxq *rxq = &trans_pcie->rxq; - struct iwl_rx_mem_buffer *rxb; - - /* - * If the device isn't enabled - not need to try to add buffers... - * This can happen when we stop the device and still have an interrupt - * pending.
