+config AR6000_WLAN

+	depends on MMC
+        select WIRELESS_EXT
+        default m
+        help
+          good luck.
+
+config AR6000_WLAN_DEBUG
+	bool "Enable retrieval of firmware debugging information"
+	depends on AR6000_WLAN
+	default n
+	help
+	  The AR6k firmware maintains a log of debugging events that
+	  gets flushed to the host on various occasions. Retrieval of
+	  this data is very slow, taking several seconds.
+
+	  If in doubt, say N.
+
+config AR6000_WLAN_RESET
+	bool "Soft-reset when shutting down"
+	depends on AR6000_WLAN
+	default n
+	help
+	  The AR6k module can be explicitly reset when shutting down
+	  the device. This adds a delay of about two seconds to suspend,
+	  module removal, and so on. Since the WLAN SDIO function is
+	  generally disabled soon thereafter anyway, this reset seems
+	  superfluous.
+
+	  If in doubt, say N.

+ *
+ * - synchronous and asynchronous requests may get reordered with respect to
+ *   each other, e.g., if HIFReadWrite returns for an asynchronous request and
+ *   then HIFReadWrite is called for a synchronous request, the synchronous
+ *   request may be executed before the asynchronous request.
+ *
+ * - request queue locking seems unnecessarily complex in the Atheros HIFs.
+ *
+ * - Atheros mask interrupts by calling sdio_claim_irq/sdio_release_irq, which
+ *   can cause quite a bit of overhead. This HIF has its own light-weight
+ *   interrupt masking.
+ *
+ * - Atheros call deviceInsertedHandler from a thread spawned off the probe or
+ *   device insertion function. The original explanation for the Atheros SDIO
+ *   stack said that this is done because a delay is needed to let the chip
+ *   complete initialization. There is indeed a one second delay in the thread.
+ *
+ *   The Atheros Linux SDIO HIF removes the delay and only retains the thread.
+ *   Experimentally removing the thread didn't show any conflicts, so let's get
+ *   rid of it for good.
+ *
+ * - The Atheros SDIO stack with Samuel's driver sets SDIO_CCCR_POWER in
+ *   SDIO_POWER_EMPC. Atheros' Linux SDIO code apparently doesn't. We don't
+ *   either, and this seems to work fine.

+/* This is a mailbox hardware unit test that must be called in a schedulable context
+ * This test is very simple, it will send a list of buffers with a counting pattern
+ * and the target will invert the data and send the message back
+ *
+ * the unit test has the following constraints:
+ *
+ * The target has at least 8 buffers of 256 bytes each. The host will send
+ * the following pattern of buffers in rapid succession :
+ *
+ * 1 buffer - 128 bytes
+ * 1 buffer - 256 bytes
+ * 1 buffer - 512 bytes
+ * 1 buffer - 1024 bytes
+ *
+ * The host will send the buffers to one mailbox and wait for buffers to be reflected
+ * back from the same mailbox. The target sends the buffers FIFO order.
+ * Once the final buffer has been received for a mailbox, the next mailbox is tested.
+ *
+ *
+ * Note:  To simplifythe test , we assume that the chosen buffer sizes
+ *        will fall on a nice block pad
+ *
+ * It is expected that higher-order tests will be written to stress the mailboxes using
+ * a message-based protocol (with some performance timming) that can create more
+ * randomness in the packets sent over mailboxes.

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to AR6K, to provide
+ * patches to code that is already resident on AR6K, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR6K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+Wireless Module Interface (WMI) Documentaion
+
+   This section describes the format and the usage model for WMI control and
+   data messages between the host and the AR6000-based targets. The header
+   file include/wmi.h contains all command and event manifest constants as
+   well as structure typedefs for each set of command and reply parameters.
+
+Data Frames
+
+   The data payload transmitted and received by the target follows RFC-1042
+   encapsulation and thus starts with an 802.2-style LLC-SNAP header. The
+   WLAN module completes 802.11 encapsulation of the payload, including the
+   MAC header, FCS, and WLAN security related fields. At the interface to the
+   message transport (HTC), a data frame is encapsulated in a WMI message.
+
+WMI Message Structure
+
+   The WMI protocol leverages an 802.3-style Ethernet header in communicating
+   the source and destination information between the host and the AR6000
+   modules using a 14-byte 802.3 header ahead of the 802.2-style payload. In
+   addition, the WMI protocol adds a header to all data messages:
+
+    {
+    INT8    rssi
+                  The RSSI of the received packet and its units are shown in db above the
+                      noise floor, and the noise floor is shown in dbm.
+    UINT8   info
+                      Contains information on message type and user priority. Message type
+                      differentiates between a data packet and a synchronization message.
+    } WMI_DATA_HDR
+
+   User priority contains the 802.1d user priority info from host to target. Host
+   software translates the host Ethernet format to 802.3 format prior to Tx and
+   802.3 format to host format in the Rx direction. The host does not transmit the
+   FCS that follows the data. MsgType differentiates between a regular data
+   packet (msgType=0) and a synchronization message (msgType=1).
+
+Data Endpoints
+
+   The AR6000 chipset provides several data endpoints to support quality of
+   service (QoS) and maintains separate queues and separate DMA engines for
+   each data endpoint. A data endpoint can be bi-directional.
+
+   Best effort (BE) class traffic uses the default data endpoint (2). The host can
+   establish up to two additional data endpoints for other traffic classes. Once
+   such a data endpoint is established, it sends and receives corresponding QoS
+   traffic in a manner similar to the default data endpoint.
+
+   If QoS is desired over the interconnect, host software must classify each data
+   packet and place it on the appropriate data endpoint. The information
+   required to classify data is generally available in-band as an 802.1p/q style
+   tag or as the ToS field in the IP header. The information may also be available
+   out-of-band depending on the host DDI.
+
+Connection States
+
+   Table B-1 describes the AR6000 WLAN connection states:
+
+   Table B-1.  AR6000 Connection States
+
+Connection State
+    Description
+
+   DISCONNECTED
+    In this state, the AR6000 device is not connected to a wireless
+   network. The device is in this state after reset when it sends the
+   WIRELESS MODULE “READY” EVENT, after it processes a
+   DISCONNECT command, and when it loses its link with the
+   access point (AP) that it was connected to. The device signals a
+   transition to the DISCONNECTED state with a “DISCONNECT”
+   event.
+
+CONNECTED
+    In this state, the AR6000 device is connected to wireless networks.
+   The device enters this state after successfully processing a
+   CONNECT, which establishes a connection with a wireless
+   network. The device signals a transition to the CONNECTED state
+   with a “CONNECT” event.
+
+
+Message Types
+
+   WMI uses commands, replies, and events for the control and configuration of
+   the AR6000 device. The control protocol is asynchronous. Table B-2 describes
+   AR6000 message types:
+
+Table B-2.  AR6000 Message Types
+
+Message Type
+    Description
+
+Commands
+    Control messages that flow from the host to the device
+
+Replies/Events
+    Control messages that flow from the device to the host.
+
+   The device issues a reply to some WMI commands, but not to others.
+   The payload in a reply is command-specific, and some commands do
+   not trigger a reply message at all. Events are control messages issued
+   by the device to signal the occurrence of an asynchronous event.
+
+
+WMI Message Format
+
+   All WMI control commands, replies and events use the header format:
+
+   WMI_CMD_HDR Header Format
+   {
+        UINT16 id
+                 This 16-bit constant identifies which WMI command the host is issuing,
+                 which command the target is replying to, or which event has occurred.
+        WMI_CMD_HDR
+   }
+
+
+   A variable-size command-, reply-, or event-specific payload follows the
+   header. Over the interconnect, all fields in control messages (including
+   WMI_CMD_HDR and the command specific payload) use 32-bit little Endian
+   byte ordering and fields are packed. The AR6000 device always executes
+   commands in order, and the host may send multiple commands without
+   waiting for previous commands to complete. A majority of commands are
+   processed to completion once received. Other commands trigger a longer
+   duration activity whose completion is signaled to the host through an event.
+
+Command Restrictions
+
+   Some commands may only be issued when the AR6000 device is in a certain
+   state. The host is required to wait for an event signaling a state transition
+   before such a command can be issued. For example, if a command requires
+   the device to be in the CONNECTED state, then the host is required to wait
+   for a “CONNECT” event before it issues that command.
+
+   The device ignores any commands inappropriate for its current state. If the
+   command triggers a reply, the device generates an error reply. Otherwise, the
+   device silently ignores the inappropriate command.
+
+Command and Data Synchronization
+
+   WMI provides a mechanism for a host to advise the device of necessary
+   synchronization between commands and data. The device implements
+   synchronization; no implicit synchronization exists between endpoints.
+
+   The host controls synchronization using the “SYNCHRONIZE” command
+   over the control channel and synchronization messages over data channels.
+   The device stops each data channel upon receiving a synchronization message
+   on that channel, processing all data packets received prior to that message.
+   After the device receives synchronization messages for each data endpoint
+   and the “SYNCHRONIZE” command, it resumes all channels.
+
+   When the host must guarantee a command executes before processing new
+   data packets, it first issues the command, then issues the “SYNCHRONIZE”
+   command and sends synchronization messages on data channels. When the
+   host must guarantee the device has processed all old data packets before a
+   processing a new command, it issues a “SYNCHRONIZE” command and
+   synchronization messages on all data channels, then issues the desired
+   command.

+    ADD_WOW_PATTERN
+
+Synopsis
+    The host uses this command to add a pattern to the WoW pattern list; used for
+    pattern-matching for host wakeups by the WoW module. If the host mode is asleep
+    and WoW is enabled, all packets are matched against the existing WoW patterns. If a
+    packet matches any of the patterns specified, the target will wake up the host. All
+    non-matching packets are discarded by the target without being sent up to the host.

+    CONNECT_CMD
+
+Synopsis
+    New connect control information (connectCtrl) is added, with 32 possible modifiers.
+
+    CONNECT_SEND_REASSOC
+        Valid only for a host-controlled connection to a
+        particular AP. If this bit is set, a reassociation frame is
+        sent. If this bit is clear, an association request frame is
+        sent to the AP.
+
+    CONNECT_IGNORE_WPAx_GROUP_CIPHER
+        No group key is issued in the CONNECT command,
+        so use the group key advertised by the AP. In a target-
+        initiated roaming situation this allows a STA to roam
+        between APs that support different multicast ciphers.
+
+    CONNECT_PROFILE_MATCH_DONE
+        In a host-controlled connection case, it is possible that
+        during connect, firmware may not have the
+        information for a profile match (e.g, when the AP
+        supports hidden SSIDs and the device may not
+        transmit probe requests during connect). By setting
+        this bit in the connection control information, the
+        firmware waits for a beacon from the AP with the
+        BSSID supplied in the CONNECT command. No
+        additional profile checks are done.
+
+    CONNECT_IGNORE_AAC_BEACON
+        Ignore the Admission Capacity information in the
+        beacon of the AP
+
+    CONNECT_ASSOC_POLICY_USER
+        When set, the CONNECT_SEND_REASSOC setting
+        determines if an Assoc or Reassoc is sent to an AP

+Name
+    CREATE_PSTREAM
+
+Synopsis
+    The host uses this command to create a new prioritized data endpoint between the
+    host and the AR6000 device that carries a prioritized stream of data. If the AP that the
+    device connects to requires TSPEC stream establishment, the device requests the
+    corresponding TSPEC with the AP. The maximum and minimum service interval
+    ranges from 0 – 0x7FFFFFFF (ms), where 0 = disabled. The device does not send a
+    reply event for this command, as it is always assumed the command has succeeded.
+    An AP admission control response comes to the host via a WMI_CAC_INDICATION
+    event, once the response for the ADDTS frame comes.
+
+    Examples of cases where reassociation is generated (when WMM) and cases where
+    ADDTS is generated (when WMM and enabling ACM) are when:
+        Changing UAPSD flags in WMM mode, reassociation is generated
+        Changing the interval of sending auto QoS Null frame in WMM mode;
+            reassociation is not generated
+        Issuing a command with same previous parameters in WMM mode and enabling
+            ACM, an ADDTS request is generated
+        Changing the interval of a QoS null frame sending in WMM mode and enabling
+            ACM, an ADDTS request is generated
+        Issuing the command in disconnected state, reassociation or ADDTS is not
+            generated but the parameters are available after (re)association

+    SET_CHANNEL_PARAMETERS
+
+Synopsis
+    Configures various WLAN parameters related to channels, sets the wireless mode,
+    and can restrict the AR6000 device to a subset of available channels. The list of
+    available channels varies depending on the wireless mode and the regulatory
+    domain. The device never operates on a channel outside of its regulatory domain. The
+    device starts to scan the list of channels right after this command.

+    wmiconfig eth1 --wmode <mode> <list>
+
+Command Parameters
+    UINT8    phyMode    See Values below.
+    UINT8    numberOfChannels
+        Number of channels in the channel array that
+        follows. If = 0, then the device uses all of the
+        channels permitted by the regulatory domain
+        and by the specified phyMode.

+    SET_DISC_TIMEOUT
+
+Synopsis
+    The host uses this command to configure the amount of time that the AR6000 should
+    spend when it attempts to reestablish a connection after losing link with its current
+    BSS. If this time limit is exceeded, the AR6000 send a “DISCONNECT” event. After
+    sending the “DISCONNECT” event the AR6000 continues to attempt to reestablish a
+    connection, but they do so at the interval corresponding to a foreground scan as
+    established by the “SET_SCAN_PARAMS” command.
+
+    A timeout value of 0 indicates that the AR6000 will disable all autonomous roaming,
+    so that the AR6000 will not perform any scans after sending a “DISCONNECT”
+    event to the host. The state is maintained until a shutdown or host sets different
+    timeout value from 0.

+Command Parameters
+    UINT8    disconnectTimeout
+        Specifies the time limit (in seconds) after

+    SET_FIXRATES
+
+Synopsis
+    By default, the AR6000 device uses all PHY rates based on mode of operation. If the
+    host application requires the device to use subset of supported rates, it can set those
+    rates with this command. In 802.11g mode, the AR6000 device takes the entire
+    802.11g basic rate set and the rates specified with this command and uses it as the
+    supported rate set.
+
+    This rate set is advertised in the probe request and the assoc/re-assoc request as
+    supported rates. Upon successful association, the device modifies the rate set pool
+    using the: intersection of AP-supported rates with the union of the 802.11g basic rate
+    set and rates set using this command. The device picks transmission rates from this
+    pool based on a rate control algorithm.
+
+Command
+    TBD
+
+Command Parameters
+    A_UINT16    fixRateMask;
+        The individual bit is an index for rate table,

+
+Synopsis
+    Used to support a non-standard power management scheme for an ad hoc wireless
+    network consisting of up to eight stations (STAs) that support this form of power
+    saving (e.g., Atheros-based STAs). A thorough understanding of IEEE 802.11 ad hoc
+    networks is required to use this command effectively.

+    wmiconfig eth1 --ibsspmcaps --ps=<enable/disable>
+        --aw=<ATIM Windows in ms>
+        --ttl=<Time to live in number of beacon periods>
+        --to=<timeout in ms>
+
+Command Parameters
+    UINT8    power_saving
+        = 0
+        The non-standard power saving scheme is
+        disabled and maximum throughput (with no
+        power saving) is obtained.
+
+        = 1
+        Ad hoc power saving scheme is enabled (but
+        throughput may be decreased)
+
+    UINT16    atim_windows
+        Specifies the length (in ms) of the ad hoc traffic
+        indication message (ATIM) windows used in an ad
+        hoc network. All Atheros-based STAs that join the
+        network use this duration ATIM window.
+
+    The duration is communicated between wireless
+    STAs through an IE in beacons and probe responses.
+
+    The host sets atim_windows to control trade-offs
+    between power use and throughput. The value
+    chosen should be based on the beacon interval (see
+    the “SET_BEACON_INT” command) on the
+    expected number of STAs in the IBSS, and on the
+    amount of traffic and traffic patterns between STAs.
+
+    UINT16    timeout_value
+        Specifies the timeout (in ms). The value is the same
+        for all ad hoc connections, but tracks separately for
+        each.
+
+        Applicable only for a beacon period and used to
+        derive actual timeout values on the Tx and Rx sides.
+        On the Tx side, the value defines a window during
+        which the STA accepts the frame(s) from the host for a
+        particular connection. Until closed, the window
+        restarts with every frame received from the host. On
+        the Rx side, indicates the time until which the STA
+        continues accepting frames from a particular
+        connection. The value resets with every frame
+        received. The value can be used to determine the
+        trade off between throughput and power.
+        Default = 10 ms
+
+    UINT8    ttl
+        Specifies the value in number of beacon periods. The
+        value is used to set a limit on the time until which a
+        frame is kept alive in the AR6001 before being
+        discarded. Default = 5
+
+Command Values
+    None
+
+Reset Values

+
+Synopsis
+    The host uses this command to provide the AR6000 device with guidelines on the
+    desired trade-off between power utilization and performance.
+
+        In normal power mode, the device enters a sleep state if they have nothing to do,
+        which conserves power but may cost performance as it can take up to 2 ms to
+        resume operation after leaving sleep state.
+
+        In maximum performance mode, the device never enters sleep state, thus no time
+        is spent waking up, resulting in higher power consumption and better
+        performance.

+Name
+    SET_ROAM_CTRL
+
+Synopsis
+    Affects how the AR6000 device selects a BSS. The host uses this command to set and
+    enable low RSSI scan parameters. The time period of low RSSI background scan is
+    mentioned in scan period. Low RSSI scan is triggered when the current RSSI
+    threshold (75% of current RSSI) is equal to or less than scan threshold.
+
+    Low RSSI roam is triggered when the current RSSI threshold falls below the roam
+    threshold and roams to a better AP by the end of the scan cycle. During Low RSSI
+    roam, if the STA finds a new AP with an RSSI greater than roam RSSI to floor, during
+    scan, it roams immediately to it instead of waiting for the end of the scan cycle. See
+    also “Scan and Roam” on page C-1.

+
+Name
+    SET_SCAN_PARAMS
+
+Synopsis
+    The host uses this command to set the AR6000 scan parameters, including the duty
+    cycle for both foreground and background scanning. Foreground scanning takes
+    place when the AR6000 device is not connected, and discovers all available wireless
+    networks to find the best BSS to join. Background scanning takes place when the
+    device is already connected to a network and scans for potential roaming candidates
+    and maintains them in order of best to worst. A second priority of background
+    scanning is to find new wireless networks.
+
+    The device initiates a scan when necessary. For example, a foreground scan is always
+    started on receipt of a “CONNECT_CMD” command or when the device cannot find
+    a BSS to connect to. Foreground scanning is disabled by default until receipt of a
+    CONNECT command. Background scanning is enabled by default and occurs every
+    60 seconds after the device is connected.
+
+    The device implements a binary backoff interval for foreground scanning when it
+    enters the DISCONNECTED state after losing connectivity with an AP or when a
+    CONNECT command is received. The first interval is ForegroundScanStartPeriod,
+    which doubles after each scan until the interval reaches ForegroundScanEndPeriod.
+    If the host terminates a connection with DISCONNECT, the foreground scan period
+    is ForegroundScanEndPeriod. All scan intervals are measured from the time a full
+    scan ends to the time the next full scan starts. The host starts a scan by issuing a
+    “START_SCAN” command. See also “Scan and Roam” on page C-1.

+
+Command Parameters
+    UINT16    fgStartPeriod

+        disconnects from an AP or receives a
+        CONNECT command, specified in seconds (0–
+        65535). If = 0, the device uses the reset value.
+        If = 65535, the device disables foreground
+        scanning.
+
+    UINT16    fgEndPeriod
+        The maximum interval the device waits between
+        foreground scans specified in seconds (from

+        device uses the reset value.
+
+    UINT16    bgScanPeriod
+        The period of background scan specified in
+        seconds (0–65535). By default, it is set to the reset

+        device disables background scanning.
+
+    UINT16    maxactChDwellTime
+        The period of time the device stays on a
+        particular channel while active scanning. It is

+
+    UINT16    PasChDwellTime
+        The period of time the device remains on a

+    response frames please consult the IEEE 802.11 specification.
+
+    The beacons or probe responses containing the IE specified by the
+    WMI_BSS_FILTER_CMD are passed to the host through the
+    WMI_BSSINFO_EVENT. The event carries a 32-bit bitmask that indicates the IEs that
+    were detected in the management frame. The frame type field has been extended to
+    indicate action management frames. This would be helpful to route these frames
+    through the same event mechanism as used by the beacon processing function.
+
+    If the bssFilter in the SET_BSS_FILTER matches, then the ieMask is not relevant
+    because the BSSINFO event is sent to the host. If the bssFilter doesnot match in the
+    beacons/probe respones, then the ieMask match dictates whether the BSSINFO
+    event is sent to the host. In the case of action management frames, the ieMask is the
+    filter that is applied.

+
+WMI Extension Commands
+
+The WMI EXTENSION command is used to multiplex a collection of
+commands that:
+
+        Are not generic wireless commands
+        May be implementation-specific
+        May be target platform-specific
+        May be optional for a host implementation
+
+    An extension command is sent to the AR6000 targets like any other WMI
+command message and uses the WMI_EXTENSION. The first field of the
+payload for this EXTENSION command is another commandId, sometimes
+called the subcommandId, which indicates which extension command is
+being used. A subcommandId-specific payload follows the subcommandId.
+
+All extensions (subcommandIds) are listed in the header file include/wmix.h.
+See also “WMI Extension Events” on page B-58.
