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

368  *     3:  CT_KILL_EXIT
369  *         Host sets this to request exit from CT_KILL state, i.e. host thinks
370  *         device temperature is low enough to continue normal operation.
371  *     2:  CMD_BLOCKED
372  *         Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
373  *         to release uCode to clear all Tx and command queues, enter
374  *         unassociated mode, and power down.
375  *         NOTE:  Some devices also use HBUS_TARG_MBX_C register for this bit.
376  *     1:  SW_BIT_RFKILL
377  *         Host sets this when issuing CARD_STATE command to request
378  *         device sleep.
379  *     0:  MAC_SLEEP
380  *         uCode sets this when preparing a power-saving power-down.
381  *         uCode resets this when power-up is complete and SRAM is sane.
382  *         NOTE:  device saves internal SRAM data to host when powering down,
383  *                and must restore this data after powering back up.
384  *                MAC_SLEEP is the best indication that restore is complete.
385  *                Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
386  *                do not need to save/restore it.

1116 /**
1117  * Tx Scheduler
1118  *
1119  * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
1120  * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
1121  * host DRAM.  It steers each frame's Tx command (which contains the frame
1122  * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
1123  * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
1124  * but one DMA channel may take input from several queues.
1125  *
1126  * Tx DMA FIFOs have dedicated purposes.
1127  *
1128  * For 5000 series and up, they are used differently
1129  * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
1130  *
1131  * 0 -- EDCA BK (background) frames, lowest priority
1132  * 1 -- EDCA BE (best effort) frames, normal priority
1133  * 2 -- EDCA VI (video) frames, higher priority
1134  * 3 -- EDCA VO (voice) and management frames, highest priority
1135  * 4 -- unused
1136  * 5 -- unused
1137  * 6 -- unused
1138  * 7 -- Commands
1139  *
1140  * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
1141  * In addition, driver can map the remaining queues to Tx DMA/FIFO
1142  * channels 0-3 to support 11n aggregation via EDCA DMA channels.
1143  *
1144  * The driver sets up each queue to work in one of two modes:
1145  *
1146  * 1)  Scheduler-Ack, in which the scheduler automatically supports a
1147  *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
1148  *     contains TFDs for a unique combination of Recipient Address (RA)
1149  *     and Traffic Identifier (TID), that is, traffic of a given
1150  *     Quality-Of-Service (QOS) priority, destined for a single station.
1151  *
1152  *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
1153  *     each frame within the BA window, including whether it's been transmitted,
1154  *     and whether it's been acknowledged by the receiving station.  The device
1155  *     automatically processes block-acks received from the receiving STA,
1156  *     and reschedules un-acked frames to be retransmitted (successful
1157  *     Tx completion may end up being out-of-order).
1158  *
1159  *     The driver must maintain the queue's Byte Count table in host DRAM
1160  *     for this mode.
1161  *     This mode does not support fragmentation.
1162  *
1163  * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
1164  *     The device may automatically retry Tx, but will retry only one frame
1165  *     at a time, until receiving ACK from receiving station, or reaching
1166  *     retry limit and giving up.
1167  *
1168  *     The command queue (#4/#9) must use this mode!
1169  *     This mode does not require use of the Byte Count table in host DRAM.
1170  *
1171  * Driver controls scheduler operation via 3 means:
1172  * 1)  Scheduler registers
1173  * 2)  Shared scheduler data base in internal SRAM
1174  * 3)  Shared data in host DRAM
1175  *
1176  * Initialization:
1177  *
1178  * When loading, driver should allocate memory for:
1179  * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
1180  * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
1181  *     (1024 bytes for each queue).
1182  *
1183  * After receiving "Alive" response from uCode, driver must initialize
1184  * the scheduler (especially for queue #4/#9, the command queue, otherwise
1185  * the driver can't issue commands!):

1364  * physical address of each into device registers:
1365  *
1366  * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
1367  *     entries (although any power of 2, up to 4096, is selectable by driver).
1368  *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
1369  *     (typically 4K, although 8K or 16K are also selectable by driver).
1370  *     Driver sets up RB size and number of RBDs in the CB via Rx config
1371  *     register IWM_FH_MEM_RCSR_CHNL0_CONFIG_REG.
1372  *
1373  *     Bit fields within one RBD:
1374  *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
1375  *
1376  *     Driver sets physical address [35:8] of base of RBD circular buffer
1377  *     into IWM_FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
1378  *
1379  * 2)  Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
1380  *     (RBs) have been filled, via a "write pointer", actually the index of
1381  *     the RB's corresponding RBD within the circular buffer.  Driver sets
1382  *     physical address [35:4] into IWM_FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
1383  *
1384  *     Bit fields in lower dword of Rx status buffer (upper dword not used
1385  *     by driver:
1386  *     31-12:  Not used by driver
1387  *     11- 0:  Index of last filled Rx buffer descriptor
1388  *             (device writes, driver reads this value)
1389  *
1390  * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
1391  * enter pointers to these RBs into contiguous RBD circular buffer entries,
1392  * and update the device's "write" index register,
1393  * IWM_FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
1394  *
1395  * This "write" index corresponds to the *next* RBD that the driver will make
1396  * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
1397  * the circular buffer.  This value should initially be 0 (before preparing any
1398  * RBs), should be 8 after preparing the first 8 RBs (for example), and must
1399  * wrap back to 0 at the end of the circular buffer (but don't wrap before
1400  * "read" index has advanced past 1!  See below).
1401  * NOTE:  DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
1402  *
1403  * As the device fills RBs (referenced from contiguous RBDs within the circular
1404  * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
1405  * to tell the driver the index of the latest filled RBD.  The driver must
1406  * read this "read" index from DRAM after receiving an Rx interrupt from device
1407  *
1408  * The driver must also internally keep track of a third index, which is the
1409  * next RBD to process.  When receiving an Rx interrupt, driver should process
1410  * all filled but unprocessed RBs up to, but not including, the RB
1411  * corresponding to the "read" index.  For example, if "read" index becomes "1",
1412  * driver may process the RB pointed to by RBD 0.  Depending on volume of
1413  * traffic, there may be many RBs to process.
1414  *
1415  * If read index == write index, device thinks there is no room to put new data.
1416  * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
1417  * be safe, make sure that there is a gap of at least 2 RBDs between "write"
1418  * and "read" indexes; that is, make sure that there are no more than 254
1419  * buffers waiting to be filled.
