1264 /**
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.

1928 * Dynamic Queue Allocation (AKA "DQA") is a feature implemented in iwlwifi
1929 * to allow dynamic allocation of queues on-demand, rather than allocate them
1930 * statically ahead of time. Ideally, we would like to allocate one queue
1931 * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2
1932 * even if it also needs to send traffic to a sleeping STA1, without being
1933 * blocked by the sleeping station.
1934 *
1935 * Although the queues in DQA mode are dynamically allocated, there are still
1936 * some queues that are statically allocated:
1937 * TXQ #0 - command queue
1938 * TXQ #1 - aux frames
1939 * TXQ #2 - P2P device frames
1940 * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames
1941 * TXQ #4 - BSS DATA frames queue
1942 * TXQ #5-8 - non-QoS data, QoS no-data, and MGMT frames queue pool
1943 * TXQ #9 - P2P GO/SoftAP probe responses
1944 * TXQ #10-31 - QoS DATA frames queue pool (for Tx aggregation)

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.
2780 */
2781
2782 /**
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?

4332 * energy delta 5dB.
4333 * @bf_roaming_energy_delta: Used for RSSI filtering, if in 'roaming' state.
4334 * Send beacon to driver if delta in Energy values calculated for this
4335 * and last passed beacon is greater than this threshold. Zero value
4336 * means that the Energy change is ignored for beacon filtering while in
4337 * Roaming state, typical energy delta 1dB.

4343 * filtering (Slow or Fast) that is selected (Units are in Celsuis):
4344 * If the current temperature is above this threshold - Fast filter
4345 * will be used, If the current temperature is below this threshold -
4346 * Slow filter will be used.
4347 * @bf_temp_fast_filter: Send Beacon to driver if delta in temperature values
4348 * calculated for this and the last passed beacon is greater than this
4349 * threshold. Zero value means that the temperature change is ignored for
4350 * beacon filtering; beacons will not be forced to be sent to driver
4351 * regardless of whether its temerature has been changed.
4352 * @bf_temp_slow_filter: Send Beacon to driver if delta in temperature values
4353 * calculated for this and the last passed beacon is greater than this
4354 * threshold. Zero value means that the temperature change is ignored for
4355 * beacon filtering; beacons will not be forced to be sent to driver
4356 * regardless of whether its temerature has been changed.
4357 * @bf_enable_beacon_filter: 1, beacon filtering is enabled; 0, disabled.

4359 * for a specific period of time. Units: Beacons.
4360 * @ba_escape_timer: Fully receive and parse beacon if no beacons were passed
4361 * for a longer period of time then this escape-timeout. Units: Beacons.

6819 * As the firmware is slowly running out of command IDs and grouping of
6820 * commands is desirable anyway, the firmware is extending the command
6821 * header from 4 bytes to 8 bytes to introduce a group (in place of the
6822 * former flags field, since that's always 0 on commands and thus can
6823 * be easily used to distinguish between the two).
6824 *
6825 * These functions retrieve specific information from the id field in
6826 * the iwm_host_cmd struct which contains the command id, the group id,
6827 * and the version of the command.
