+/* -------- FIQ handler in C ---------
+ *
+ * Major Caveats for using this
+ * ---------------------------
+ * *
+ * * 1) it CANNOT touch any vmalloc()'d memory, only memory
+ * that was kmalloc()'d. Static allocations in the monolithic kernel
+ * are kmalloc()'d so they are okay. You can touch memory-mapped IO, but
+ * the pointer for it has to have been stored in kmalloc'd memory. The
+ * reason for this is simple: every now and then Linux turns off interrupts
+ * and reorders the paging tables. If a FIQ happens during this time, the
+ * virtual memory space can be partly or entirely disordered or missing.
+ *
+ * 2) Because vmalloc() is used when a module is inserted, THIS FIQ
+ * ISR HAS TO BE IN THE MONOLITHIC KERNEL, not a module. But the way
+ * it is set up, you can all to enable and disable it from your module
+ * and intercommunicate with it through struct fiq_ipc
+ * fiq_ipc which you can define in
+ * asm/archfiq_ipc_type.h. The reason is the same as above, a
+ * FIQ could happen while even the ISR is not present in virtual memory
+ * space due to pagetables being changed at the time.
+ *
+ * 3) You can't call any Linux API code except simple macros
+ * - understand that FIQ can come in at any time, no matter what
+ * state of undress the kernel may privately be in, thinking it
+ * locked the door by turning off interrupts... FIQ is an
+ * unstoppable monster force (which is its value)
+ * - they are not vmalloc()'d memory safe
+ * - they might do crazy stuff like sleep: FIQ pisses fire and
+ * is not interested in 'sleep' that the weak seem to need
+ * - calling APIs from FIQ can re-enter un-renterable things
+ * - summary: you cannot interoperate with linux APIs directly in the FIQ ISR
+ *
+ * If you follow these rules, it is fantastic, an extremely powerful, solid,
+ * genuine hard realtime feature.

+ * Differences from Atheros' HIFs:
+ *
+ * - 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.

+ * It is used to download an application to AR6K, to provide

+ * 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).

+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.

+ 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

+ 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

+ --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

+ SET_POWER_MODE
+
+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.
+

+ TBD
+
+Command Parameters
+ UINT8 powerMode
+ WMI_POWER_MODE value
+ {
+ REC_POWER = 1
+ (Recommended setting) Tries to conserve
+ power without sacrificing performance
+ MAX_PERF_POWER = 2
+ Setting that maximizes performance at

+
+ All other values are reserved
+ } WMI_POWER_MODE
+
+Command Values
+ See command parameters
+
+Reset Values
+ powerMode is REC_POWER
+
+Restrictions
+ This command should only be issued in the DISCONNECTED state for the
+ infrastructure network.
+
+ For a PM-disabled ad hoc network, the power mode should remain in
+ MAX_PERF_POWER.
+
+ For a PM-enabled ad hoc network, the device can have REC_POWER or
+ MAX_PERF_POWER set, but either way it must follow the power save ad hoc
+ protocol. The host can change power modes in the CONNECTED state.
+
+ Host changes to the PS setting when the STA is off the home channel take no effect
+ and cause a TARGET_PM_FAIL event.

+
+ Low RSSI roam is triggered when the current RSSI threshold falls below the roam

+
+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.

+ If = 65535, the device disables foreground
+ scanning.
+
+ UINT16 fgEndPeriod
+ The maximum interval the device waits between
+ foreground scans specified in seconds (from
+ ForegroundScanStartPeriod to 65535). If = 0, the
+ 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
+ value of 60 seconds. If 0 or 65535 is specified, the
+ device disables background scanning.
+
+ UINT16 maxactChDwellTime

+
+ UINT16 PasChDwellTime

+Name
+ BSSINFO
+
+Synopsis
+ Contains information describing one or more BSSs as collected during a scan.
+ Information includes the BSSID, SSID, RSSI, network type, channel, supported rates,
+ and IEs. BSSINFO events are sent only after the device receives a beacon or probe-
+ response frame that pass the filter specified in the “SET_BSS_FILTER” command.
+ BSSINFO events consist of a small header followed by a copy of the beacon or probe
+ response frame. The 802.11 header is not present. For formats of beacon and probe-
+ 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.

+WMI Extension Events
+
+The WMI EXTENSION event is used for a collection of events that:
+
+ Are not generic wireless events
+ May be implementation-specific
+ May be target platform-specific
+ May be optional for a host implementation
+
+ An extension event is sent from the AR6000 device targets to the host just like
+any other WMI event message, using the WMI_EXTENSION_EVENTID. The
+first field of the payload for this “EXTENSION” event is another commandId
+(sometimes called the subcommandId) that indicates which “EXTENSION”
+event 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 Commands” on page B-55.
+
+
+WMI Extension Events
+
+
+GPIO_ACK
+ Acknowledges a host set command has been processed by the device
+
+GPIO_DATA
+ Response to a host’s request for data
+
+GPIO_INTR
+ Signals that GPIO interrupts are pending
+
+
+=====================================================================
+
+Name
+ GPIO_ACK
+
+Synopsis
+ Acknowledges that a host set command (either “GPIO_OUTPUT_SET” or
+ “GPIO_REGISTER_SET”) has been processed by the AR6000 device.
+
+NOTE: Support for GPIO is optional.
+

+=====================================================================
+
+
+Name
+ GPIO_DATA
+
+Synopsis
+ The AR6000 device uses this event to respond to the host’s earlier request for data
+ (through either a “GPIO_REGISTER_GET” or a “GPIO_INPUT_GET” command).
+
+NOTE: Support for GPIO is optional.
+
+Event ID
+ N/A
+
+Event Parameters
+ UINT32 value
+ Holds the data of interest, which is either a register value
+ (in the case of “GPIO_REGISTER_GET”) or a mask of
+ pin inputs (in the case of “GPIO_INPUT_GET”).
+ UINT32 reg_id
+ Indicates which register was read (in the case of
+ “GPIO_REGISTER_GET”) or is GPIO_ID_NONE (in the
+ case of “GPIO_INPUT_GET”)
+
+Event Values
+ None
+
+
+=====================================================================
+
+
+
+Name
+ GPIO_INTR
+
+Synopsis
+ The AR6000 device raises this event to signal that GPIO interrupts are pending.
+ These GPIOs may be interrupts that occurred after the last “GPIO_INTR_ACK”
+ command was issued, or may be GPIO interrupts that the host failed to acknowledge
+ in the last “GPIO_INTR_ACK”. The AR6000 will not raise another GPIO_INTR
+ event until this event is acknowledged through a “GPIO_INTR_ACK” command.
+
+NOTE: Support for GPIO is optional.
+
+Event ID
+ N/A
+
+Event Parameters
+ UINT32 intr_mask
+ Indicates which GPIO interrupts are currently pending
+
+ UINT32 input_values
+ A recent copy of the GPIO input values, taken at the
+ time the most recent GPIO interrupt was processed
+
+Event Values
+ None
+

+ * This filter is useful to reject samples that are not reliable. We consider

+ *
+ * The implementation would be more efficient with a double-linked list but

+ *
+ * 1) We collect S samples and keep it in sorted sets.
+ * - Points that are "close enough" are considered to be in the same set.
+ * We don't actually keep the sets but ranges of points.
+ *
+ * 2) For each dimension:
+ * - We choose the range with more elements. If more than "threshold"
+ * points are in this range we use the minimum and the maximum point
+ * of the range to define the valid range for this dimension [min, max],
+ * otherwise we discard all the points and the ranges and go to step 1.
+ *
+ * 3) We consider the unsorted S samples and try to feed them to the next
+ * filter in the chain. If one of the points of each sample
