     75  * CSR (control and status registers)
     76  *
     77  * CSR registers are mapped directly into PCI bus space, and are accessible
     78  * whenever platform supplies power to device, even when device is in
     79  * low power states due to driver-invoked device resets
     80  * (e.g. IWM_CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.
     81  *
     82  * Use iwl_write32() and iwl_read32() family to access these registers;
     83  * these provide simple PCI bus access, without waking up the MAC.
     84  * Do not use iwl_write_direct32() family for these registers;
     85  * no need to "grab nic access" via IWM_CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
     86  * The MAC (uCode processor, etc.) does not need to be powered up for accessing
     87  * the CSR registers.
     88  *
     89  * NOTE:  Device does need to be awake in order to read this memory
     90  *        via IWM_CSR_EEPROM and IWM_CSR_OTP registers

    357  *         Host sets this to request exit from CT_KILL state, i.e. host thinks

    359  *     2:  CMD_BLOCKED
    360  *         Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
    361  *         to release uCode to clear all Tx and command queues, enter
    362  *         unassociated mode, and power down.
    363  *         NOTE:  Some devices also use HBUS_TARG_MBX_C register for this bit.

    365  *         Host sets this when issuing CARD_STATE command to request
    366  *         device sleep.
    367  *     0:  MAC_SLEEP
    368  *         uCode sets this when preparing a power-saving power-down.
    369  *         uCode resets this when power-up is complete and SRAM is sane.
    370  *         NOTE:  device saves internal SRAM data to host when powering down,

   1065 /**
   1066  * Tx Scheduler
   1067  *
   1068  * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
   1069  * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
   1070  * host DRAM.  It steers each frame's Tx command (which contains the frame
   1071  * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
   1072  * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
   1073  * but one DMA channel may take input from several queues.
   1074  *
   1075  * Tx DMA FIFOs have dedicated purposes.
   1076  *
   1077  * For 5000 series and up, they are used differently
   1078  * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
   1079  *
   1080  * 0 -- EDCA BK (background) frames, lowest priority
   1081  * 1 -- EDCA BE (best effort) frames, normal priority
   1082  * 2 -- EDCA VI (video) frames, higher priority
   1083  * 3 -- EDCA VO (voice) and management frames, highest priority
   1084  * 4 -- unused
   1085  * 5 -- unused
   1086  * 6 -- unused
   1087  * 7 -- Commands
   1088  *
   1089  * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
   1090  * In addition, driver can map the remaining queues to Tx DMA/FIFO
   1091  * channels 0-3 to support 11n aggregation via EDCA DMA channels.
   1092  *
   1093  * The driver sets up each queue to work in one of two modes:
   1094  *
   1095  * 1)  Scheduler-Ack, in which the scheduler automatically supports a
   1096  *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
   1097  *     contains TFDs for a unique combination of Recipient Address (RA)
   1098  *     and Traffic Identifier (TID), that is, traffic of a given
   1099  *     Quality-Of-Service (QOS) priority, destined for a single station.
   1100  *
   1101  *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
   1102  *     each frame within the BA window, including whether it's been transmitted,
   1103  *     and whether it's been acknowledged by the receiving station.  The device
   1104  *     automatically processes block-acks received from the receiving STA,
   1105  *     and reschedules un-acked frames to be retransmitted (successful
   1106  *     Tx completion may end up being out-of-order).
   1107  *
   1108  *     The driver must maintain the queue's Byte Count table in host DRAM
   1109  *     for this mode.
   1110  *     This mode does not support fragmentation.
   1111  *
   1112  * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
   1113  *     The device may automatically retry Tx, but will retry only one frame
   1114  *     at a time, until receiving ACK from receiving station, or reaching
   1115  *     retry limit and giving up.
   1116  *
   1117  *     The command queue (#4/#9) must use this mode!
   1118  *     This mode does not require use of the Byte Count table in host DRAM.
   1119  *
   1120  * Driver controls scheduler operation via 3 means:
   1121  * 1)  Scheduler registers
   1122  * 2)  Shared scheduler data base in internal SRAM
   1123  * 3)  Shared data in host DRAM
   1124  *
   1125  * Initialization:
   1126  *
   1127  * When loading, driver should allocate memory for:
   1128  * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
   1129  * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
   1130  *     (1024 bytes for each queue).
   1131  *
   1132  * After receiving "Alive" response from uCode, driver must initialize
   1133  * the scheduler (especially for queue #4/#9, the command queue, otherwise
   1134  * the driver can't issue commands!):

   1294  * Rx SRAM Control and Status Registers (RSCSR)
   1295  *
   1296  * These registers provide handshake between driver and device for the Rx queue
   1297  * (this queue handles *all* command responses, notifications, Rx data, etc.
   1298  * sent from uCode to host driver).  Unlike Tx, there is only one Rx
   1299  * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
   1300  * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
   1301  * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
   1302  * mapping between RBDs and RBs.
   1303  *
   1304  * Driver must allocate host DRAM memory for the following, and set the
   1305  * physical address of each into device registers:
   1306  *
   1307  * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
   1308  *     entries (although any power of 2, up to 4096, is selectable by driver).
   1309  *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
   1310  *     (typically 4K, although 8K or 16K are also selectable by driver).
   1311  *     Driver sets up RB size and number of RBDs in the CB via Rx config
   1312  *     register IWM_FH_MEM_RCSR_CHNL0_CONFIG_REG.
   1313  *
   1314  *     Bit fields within one RBD:
   1315  *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
   1316  *
   1317  *     Driver sets physical address [35:8] of base of RBD circular buffer
   1318  *     into IWM_FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
   1319  *
   1320  * 2)  Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
   1321  *     (RBs) have been filled, via a "write pointer", actually the index of
   1322  *     the RB's corresponding RBD within the circular buffer.  Driver sets
   1323  *     physical address [35:4] into IWM_FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
   1324  *
   1325  *     Bit fields in lower dword of Rx status buffer (upper dword not used
   1326  *     by driver:
   1327  *     31-12:  Not used by driver
   1328  *     11- 0:  Index of last filled Rx buffer descriptor
   1329  *             (device writes, driver reads this value)
   1330  *
   1331  * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
   1332  * enter pointers to these RBs into contiguous RBD circular buffer entries,
   1333  * and update the device's "write" index register,
   1334  * IWM_FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
   1335  *
   1336  * This "write" index corresponds to the *next* RBD that the driver will make
   1337  * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
   1338  * the circular buffer.  This value should initially be 0 (before preparing any
   1339  * RBs), should be 8 after preparing the first 8 RBs (for example), and must
   1340  * wrap back to 0 at the end of the circular buffer (but don't wrap before
   1341  * "read" index has advanced past 1!  See below).
   1342  * NOTE:  DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
   1343  *
   1344  * As the device fills RBs (referenced from contiguous RBDs within the circular
   1345  * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
   1346  * to tell the driver the index of the latest filled RBD.  The driver must
   1347  * read this "read" index from DRAM after receiving an Rx interrupt from device
   1348  *
   1349  * The driver must also internally keep track of a third index, which is the
   1350  * next RBD to process.  When receiving an Rx interrupt, driver should process
   1351  * all filled but unprocessed RBs up to, but not including, the RB
   1352  * corresponding to the "read" index.  For example, if "read" index becomes "1",
   1353  * driver may process the RB pointed to by RBD 0.  Depending on volume of
   1354  * traffic, there may be many RBs to process.
   1355  *
   1356  * If read index == write index, device thinks there is no room to put new data.
   1357  * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
   1358  * be safe, make sure that there is a gap of at least 2 RBDs between "write"
   1359  * and "read" indexes; that is, make sure that there are no more than 254
   1360  * buffers waiting to be filled.

   2524  * Time Events are a fw feature that allows the driver to control the presence
   2525  * of the device on the channel. Since the fw supports multiple channels
   2526  * concurrently, the fw may choose to jump to another channel at any time.
   2527  * In order to make sure that the fw is on a specific channel at a certain time
   2528  * and for a certain duration, the driver needs to issue a time event.
   2529  *
   2530  * The simplest example is for BSS association. The driver issues a time event,
   2531  * waits for it to start, and only then tells mac80211 that we can start the
   2532  * association. This way, we make sure that the association will be done
   2533  * smoothly and won't be interrupted by channel switch decided within the fw.

   2537  * DOC: The flow against the fw
   2538  *
   2539  * When the driver needs to make sure we are in a certain channel, at a certain
   2540  * time and for a certain duration, it sends a Time Event. The flow against the
   2541  * fw goes like this:
   2542  *	1) Driver sends a TIME_EVENT_CMD to the fw
   2543  *	2) Driver gets the response for that command. This response contains the
   2544  *	   Unique ID (UID) of the event.
   2545  *	3) The fw sends notification when the event starts.
