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

1265  * Tx Scheduler
1266  *
1267  * The Tx Scheduler selects the next frame to be transmitted, choosing TFDs
1268  * (Transmit Frame Descriptors) from up to 16 circular Tx queues resident in
1269  * host DRAM.  It steers each frame's Tx command (which contains the frame
1270  * data) into one of up to 7 prioritized Tx DMA FIFO channels within the
1271  * device.  A queue maps to only one (selectable by driver) Tx DMA channel,
1272  * but one DMA channel may take input from several queues.
1273  *
1274  * Tx DMA FIFOs have dedicated purposes.
1275  *
1276  * For 5000 series and up, they are used differently
1277  * (cf. iwl5000_default_queue_to_tx_fifo in iwl-5000.c):
1278  *
1279  * 0 -- EDCA BK (background) frames, lowest priority
1280  * 1 -- EDCA BE (best effort) frames, normal priority
1281  * 2 -- EDCA VI (video) frames, higher priority
1282  * 3 -- EDCA VO (voice) and management frames, highest priority
1283  * 4 -- unused
1284  * 5 -- unused
1285  * 6 -- unused
1286  * 7 -- Commands
1287  *
1288  * Driver should normally map queues 0-6 to Tx DMA/FIFO channels 0-6.
1289  * In addition, driver can map the remaining queues to Tx DMA/FIFO
1290  * channels 0-3 to support 11n aggregation via EDCA DMA channels.
1291  *
1292  * The driver sets up each queue to work in one of two modes:
1293  *
1294  * 1)  Scheduler-Ack, in which the scheduler automatically supports a
1295  *     block-ack (BA) window of up to 64 TFDs.  In this mode, each queue
1296  *     contains TFDs for a unique combination of Recipient Address (RA)
1297  *     and Traffic Identifier (TID), that is, traffic of a given
1298  *     Quality-Of-Service (QOS) priority, destined for a single station.
1299  *
1300  *     In scheduler-ack mode, the scheduler keeps track of the Tx status of
1301  *     each frame within the BA window, including whether it's been transmitted,
1302  *     and whether it's been acknowledged by the receiving station.  The device
1303  *     automatically processes block-acks received from the receiving STA,
1304  *     and reschedules un-acked frames to be retransmitted (successful
1305  *     Tx completion may end up being out-of-order).
1306  *
1307  *     The driver must maintain the queue's Byte Count table in host DRAM
1308  *     for this mode.
1309  *     This mode does not support fragmentation.
1310  *
1311  * 2)  FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order.
1312  *     The device may automatically retry Tx, but will retry only one frame
1313  *     at a time, until receiving ACK from receiving station, or reaching
1314  *     retry limit and giving up.
1315  *
1316  *     The command queue (#4/#9) must use this mode!
1317  *     This mode does not require use of the Byte Count table in host DRAM.
1318  *
1319  * Driver controls scheduler operation via 3 means:
1320  * 1)  Scheduler registers
1321  * 2)  Shared scheduler data base in internal SRAM
1322  * 3)  Shared data in host DRAM
1323  *
1324  * Initialization:
1325  *
1326  * When loading, driver should allocate memory for:
1327  * 1)  16 TFD circular buffers, each with space for (typically) 256 TFDs.
1328  * 2)  16 Byte Count circular buffers in 16 KBytes contiguous memory
1329  *     (1024 bytes for each queue).
1330  *
1331  * After receiving "Alive" response from uCode, driver must initialize
1332  * the scheduler (especially for queue #4/#9, the command queue, otherwise
1333  * the driver can't issue commands!):

1501  * Rx SRAM Control and Status Registers (RSCSR)
1502  *
1503  * These registers provide handshake between driver and device for the Rx queue
1504  * (this queue handles *all* command responses, notifications, Rx data, etc.
1505  * sent from uCode to host driver).  Unlike Tx, there is only one Rx
1506  * queue, and only one Rx DMA/FIFO channel.  Also unlike Tx, which can
1507  * concatenate up to 20 DRAM buffers to form a Tx frame, each Receive Buffer
1508  * Descriptor (RBD) points to only one Rx Buffer (RB); there is a 1:1
1509  * mapping between RBDs and RBs.
1510  *
1511  * Driver must allocate host DRAM memory for the following, and set the
1512  * physical address of each into device registers:
1513  *
1514  * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
1515  *     entries (although any power of 2, up to 4096, is selectable by driver).
1516  *     Each entry (1 dword) points to a receive buffer (RB) of consistent size
1517  *     (typically 4K, although 8K or 16K are also selectable by driver).
1518  *     Driver sets up RB size and number of RBDs in the CB via Rx config
1519  *     register IWM_FH_MEM_RCSR_CHNL0_CONFIG_REG.
1520  *
1521  *     Bit fields within one RBD:
1522  *     27-0:  Receive Buffer physical address bits [35:8], 256-byte aligned
1523  *
1524  *     Driver sets physical address [35:8] of base of RBD circular buffer
1525  *     into IWM_FH_RSCSR_CHNL0_RBDCB_BASE_REG [27:0].
1526  *
1527  * 2)  Rx status buffer, 8 bytes, in which uCode indicates which Rx Buffers
1528  *     (RBs) have been filled, via a "write pointer", actually the index of
1529  *     the RB's corresponding RBD within the circular buffer.  Driver sets
1530  *     physical address [35:4] into IWM_FH_RSCSR_CHNL0_STTS_WPTR_REG [31:0].
1531  *
1532  *     Bit fields in lower dword of Rx status buffer (upper dword not used
1533  *     by driver:
1534  *     31-12:  Not used by driver
1535  *     11- 0:  Index of last filled Rx buffer descriptor
1536  *             (device writes, driver reads this value)
1537  *
1538  * As the driver prepares Receive Buffers (RBs) for device to fill, driver must
1539  * enter pointers to these RBs into contiguous RBD circular buffer entries,
1540  * and update the device's "write" index register,
1541  * IWM_FH_RSCSR_CHNL0_RBDCB_WPTR_REG.
1542  *
1543  * This "write" index corresponds to the *next* RBD that the driver will make
1544  * available, i.e. one RBD past the tail of the ready-to-fill RBDs within
1545  * the circular buffer.  This value should initially be 0 (before preparing any
1546  * RBs), should be 8 after preparing the first 8 RBs (for example), and must
1547  * wrap back to 0 at the end of the circular buffer (but don't wrap before
1548  * "read" index has advanced past 1!  See below).
1549  * NOTE:  DEVICE EXPECTS THE WRITE INDEX TO BE INCREMENTED IN MULTIPLES OF 8.
1550  *
1551  * As the device fills RBs (referenced from contiguous RBDs within the circular
1552  * buffer), it updates the Rx status buffer in host DRAM, 2) described above,
1553  * to tell the driver the index of the latest filled RBD.  The driver must
1554  * read this "read" index from DRAM after receiving an Rx interrupt from device
1555  *
1556  * The driver must also internally keep track of a third index, which is the
1557  * next RBD to process.  When receiving an Rx interrupt, driver should process
1558  * all filled but unprocessed RBs up to, but not including, the RB
1559  * corresponding to the "read" index.  For example, if "read" index becomes "1",
1560  * driver may process the RB pointed to by RBD 0.  Depending on volume of
1561  * traffic, there may be many RBs to process.
1562  *
1563  * If read index == write index, device thinks there is no room to put new data.
1564  * Due to this, the maximum number of filled RBs is 255, instead of 256.  To
1565  * be safe, make sure that there is a gap of at least 2 RBDs between "write"
1566  * and "read" indexes; that is, make sure that there are no more than 254
1567  * buffers waiting to be filled.

1933  * blocked by the sleeping station.

1936  * some queues that are statically allocated:

1938  *	TXQ #1 - aux frames
1939  *	TXQ #2 - P2P device frames

2768  * DOC: Time Events - what is it?
2769  *
2770  * Time Events are a fw feature that allows the driver to control the presence
2771  * of the device on the channel. Since the fw supports multiple channels
2772  * concurrently, the fw may choose to jump to another channel at any time.
2773  * In order to make sure that the fw is on a specific channel at a certain time
2774  * and for a certain duration, the driver needs to issue a time event.
2775  *
2776  * The simplest example is for BSS association. The driver issues a time event,
2777  * waits for it to start, and only then tells mac80211 that we can start the
2778  * association. This way, we make sure that the association will be done
2779  * smoothly and won't be interrupted by channel switch decided within the fw.

2783  * DOC: The flow against the fw
2784  *
2785  * When the driver needs to make sure we are in a certain channel, at a certain
2786  * time and for a certain duration, it sends a Time Event. The flow against the
2787  * fw goes like this:
2788  *	1) Driver sends a TIME_EVENT_CMD to the fw
2789  *	2) Driver gets the response for that command. This response contains the
2790  *	   Unique ID (UID) of the event.
2791  *	3) The fw sends notification when the event starts.
2792  *
2793  * Of course the API provides various options that allow to cover parameters
2794  * of the flow.
2795  *	What is the duration of the event?
2796  *	What is the start time of the event?
2797  *	Is there an end-time for the event?
2798  *	How much can the event be delayed?
2799  *	Can the event be split?
2800  *	If yes what is the maximal number of chunks?
2801  *	etc...
