The wimax/i2400m.h defines the structures and constants for the
host-device protocols:
- boot / firmware upload protocol
- general data transport protocol
- control protocol
It is done in such a way that can also be used verbatim by user space.
drivers/net/wimax/i2400m.h defines all the APIs used by the core,
bus-generic driver (i2400m) and the bus specific drivers
(i2400m-BUSNAME). It also gives a roadmap to the driver
implementation.
debug-levels.h adds the core driver's debug settings.

+ * - Initial implementation
+ *
+ *
+ * GENERAL DRIVER ARCHITECTURE
+ *
+ * The i2400m driver is split in the following two major parts:
+ *
+ * - bus specific driver
+ * - bus generic driver (this part)
+ *
+ * The bus specific driver sets up stuff specific to the bus the
+ * device is connected to (USB, SDIO, PCI, tam-tam...non-authoritative
+ * nor binding list) which is basically the device-model management
+ * (probe/disconnect, etc), moving data from device to kernel and
+ * back, doing the power saving details and reseting the device.
+ *
+ * For details on each bus-specific driver, see it's include file,
+ * i2400m-BUSNAME.h
+ *
+ * The bus-generic functionality break up is:
+ *
+ * - Firmware upload: fw.c - takes care of uploading firmware to the
+ * device. bus-specific driver just needs to provides a way to
+ * execute boot-mode commands and to reset the device.
+ *
+ * - RX handling: rx.c - receives data from the bus-specific code and
+ * feeds it to the network or WiMAX stack or uses it to modify
+ * the driver state. bus-specific driver only has to receive
+ * frames and pass them to this module.
+ *
+ * - TX handling: tx.c - manages the TX FIFO queue and provides means
+ * for the bus-specific TX code to pull data from the FIFO
+ * queue. bus-specific code just pulls frames from this module
+ * to sends them to the device.
+ *
+ * - netdev glue: netdev.c - interface with Linux networking
+ * stack. Pass around data frames, and configure when the
+ * device is up and running or shutdown (through ifconfig up /
+ * down). Bus-generic only.
+ *
+ * - control ops: control.c - implements various commmands for
+ * controlling the device. bus-generic only.
+ *
+ * - device model glue: driver.c - implements helpers for the
+ * device-model glue done by the bus-specific layer
+ * (setup/release the driver resources), turning the device on
+ * and off, handling the device reboots/resets and a few simple
+ * WiMAX stack ops.
+ *
+ * Code is also broken up in linux-glue / device-glue.
+ *
+ * Linux glue contains functions that deal mostly with gluing with the
+ * rest of the Linux kernel.
+ *
+ * Device-glue are functions that deal mostly with the way the device
+ * does things and talk the device's language.
+ *
+ * device-glue code is licensed BSD so other open source OSes can take
+ * it to implement their drivers.
+ *
+ *
+ * APIs AND HEADER FILES
+ *
+ * This bus generic code exports three APIs:
+ *
+ * - HDI (host-device interface) definitions common to all busses
+ * (include/linux/wimax/i2400m.h); these can be also used by user
+ * space code.
+ * - internal API for the bus-generic code
+ * - external API for the bus-specific drivers
+ *
+ *
+ * LIFE CYCLE:
+ *
+ * When the bus-specific driver probes, it allocates a network device
+ * with enough space for it's data structue, that must contain a
+ * &struct i2400m at the top.
+ *
+ * On probe, it needs to fill the i2400m members marked as [fill], as
+ * well as i2400m->wimax_dev.net_dev and call i2400m_setup(). The
+ * i2400m driver will only register with the WiMAX and network stacks;
+ * the only access done to the device is to read the MAC address so we
+ * can register a network device. This calls i2400m_dev_start() to
+ * load firmware, setup communication with the device and configure it
+ * for operation.
+ *
+ * At this point, control and data communications are possible.
+ *
+ * On disconnect/driver unload, the bus-specific disconnect function
+ * calls i2400m_release() to undo i2400m_setup(). i2400m_dev_stop()
+ * shuts the firmware down and releases resources uses to communicate
+ * with the device.
+ *
+ * While the device is up, it might reset. The bus-specific driver has
+ * to catch that situation and call i2400m_dev_reset_handle() to deal
+ * with it (reset the internal driver structures and go back to square
+ * one).

+ *
+ * Members marked with [fill] must be filled out/initialized before

+ *
+ * @bus_tx_block_size: [fill] SDIO imposes a 256 block size, USB 16,
+ * so we have a tx_blk_size variable that the bus layer sets to
+ * tell the engine how much of that we need.
+ *
+ * @bus_pl_size_max: [fill] Maximum payload size.
+ *
+ * @bus_dev_start: [fill] Function called by the bus-generic code
+ * [i2400m_dev_start()] to setup the bus-specific communications
+ * to the the device. See LIFE CYCLE above.
+ *
+ * NOTE: Doesn't need to upload the firmware, as that is taken
+ * care of by the bus-generic code.
+ *
+ * @bus_dev_stop: [fill] Function called by the bus-generic code
+ * [i2400m_dev_stop()] to shutdown the bus-specific communications
+ * to the the device. See LIFE CYCLE above.
+ *
+ * This function does not need to reset the device, just tear down
+ * all the host resources created to handle communication with
+ * the device.
+ *
+ * @bus_tx_kick: [fill] Function called by the bus-generic code to let
+ * the bus-specific code know that there is data available in the
+ * TX FIFO for transmission to the device.
+ *
+ * This function cannot sleep.
+ *
+ * @bus_reset: [fill] Function called by the bus-generic code to reset
+ * the device in in various ways. Doesn't need to wait for the
+ * reset to finish.
+ *
+ * If warm or cold reset fail, this function is expected to do a
+ * bus-specific reset (eg: USB reset) to get the device to a
+ * working state (even if it implies device disconecction).
+ *
+ * Note the warm reset is used by the firmware uploader to
+ * reinitialize the device.
+ *
+ * IMPORTANT: this is called very early in the device setup
+ * process, so it cannot rely on common infrastructure being laid
+ * out.
+ *
+ * @bus_bm_cmd_send: [fill] Function called to send a boot-mode
+ * command. Flags are defined in 'enum i2400m_bm_cmd_flags'. This
+ * is synchronous and has to return 0 if ok or < 0 errno code in
+ * any error condition.
+ *
+ * @bus_bm_wait_for_ack: [fill] Function called to wait for a
+ * boot-mode notification (that can be a response to a previously
+ * issued command or an asynchronous one). Will read until all the
+ * indicated size is read or timeout. Reading more or less data
+ * than asked for is an error condition. Return 0 if ok, < 0 errno
+ * code on error.
+ *
+ * The caller to this function will check if the response is a
+ * barker that indicates the device going into reset mode.
+ *
+ * @bus_fw_name: [fill] name of the firmware image (in most cases,
+ * they are all the same for a single release, except that they
+ * have the type of the bus embedded in the name (eg:
+ * i2400m-fw-X-VERSION.sbcf, where X is the bus name).
+ *
+ * @bus_bm_mac_addr_impaired: [fill] Set to true if the device's MAC
+ * address provided in boot mode is kind of broken and needs to
+ * be re-read later on.
+ *
+ *
+ * @wimax_dev: WiMAX generic device for linkage into the kernel WiMAX
+ * stack. Due to the way a net_device is allocated, we need to
+ * force this to be the first field so that we can get from
+ * net_dev_priv() the right pointer.
+ *
+ * @state: device's state (as reported by it)
+ *
+ * @state_wq: waitqueue that is woken up whenever the state changes
+ *
+ * @tx_lock: spinlock to protect TX members
+ *
+ * @tx_buf: FIFO buffer for TX; we queue data here
+ *
+ * @tx_in: FIFO index for incoming data. Note this doesn't wrap around
+ * and it is always greater than @tx_out.
+ *
+ * @tx_out: FIFO index for outgoing data
+ *
+ * @tx_msg: current TX message that is active in the FIFO for
+ * appending payloads.
+ *
+ * @tx_sequence: current sequence number for TX messages from the
+ * device to the host.
+ *
+ * @tx_msg_size: size of the current message being transmitted by the
+ * bus-specific code.
+ *
+ * @tx_pl_num: total number of payloads sent
+ *
+ * @tx_pl_max: maximum number of payloads sent in a TX message
+ *
+ * @tx_pl_min: minimum number of payloads sent in a TX message
+ *
+ * @tx_num: number of TX messages sent
+ *
+ * @tx_size_acc: number of bytes in all TX messages sent
+ * (this is different to net_dev's statistics as it also counts
+ * control messages).
+ *
+ * @tx_size_min: smallest TX message sent.
+ *
+ * @tx_size_max: biggest TX message sent.
+ *
+ * @rx_lock: spinlock to protect RX members
+ *
+ * @rx_pl_num: total number of payloads received
+ *
+ * @rx_pl_max: maximum number of payloads received in a RX message
+ *
+ * @rx_pl_min: minimum number of payloads received in a RX message
+ *
+ * @rx_num: number of RX messages received

+ * control messages).
+ *
+ * @rx_size_min: smallest RX message received.
+ *
+ * @rx_size_max: buggest RX message received.
+ *
+ * @init_mutex: Mutex used for serializing the device bringup
+ * sequence; this way if the device reboots in the middle, we
+ * don't try to do a bringup again while we are tearing down the
+ * one that failed.
+ *
+ * Can't reuse @msg_mutex because from within the bringup sequence
+ * we need to send messages to the device and thus use @msg_mutex.
+ *
+ * @msg_mutex: mutex used to send control commands to the device (we
+ * only allow one at a time, per host-device interface design).
+ *
+ * @msg_completion: used to wait for an ack to a control command sent
+ * to the device.
+ *
+ * @ack_skb: used to store the actual ack to a control command if the
+ * reception of the command was successful. Otherwise, a ERR_PTR()
+ * errno code that indicates what failed with the ack reception.
+ *
+ * Only valid after @msg_completion is woken up. Only updateable
+ * if @msg_completion is armed. Only touched by
+ * i2400m_msg_to_dev().
+ *
+ * Protected by @rx_lock. In theory the command execution flow is
+ * sequential, but in case the device sends an out-of-phase or
+ * very delayed response, we need to avoid it trampling current
+ * execution.
+ *
+ * @bm_cmd_buf: boot mode command buffer for composing firmware upload
+ * commands.
+ *
+ * USB can't r/w to stack, vmalloc, etc...as well, we end up
+ * having to alloc/free a lot to compose commands, so we use these
+ * for stagging and not having to realloc all the time.
+ *
+ * This assumes the code always runs serialized. Only one thread
+ * can call i2400m_bm_cmd() at the same time.
+ *
+ * @bm_ack_buf: boot mode acknoledge buffer for staging reception of
+ * responses to commands.
+ *
+ * See @bm_cmd_buf.
+ *
+ * @work_queue: work queue for processing device reports. This
+ * workqueue cannot be used for processing TX or RX to the device,
+ * as from it we'll process device reports, which might require
+ * further communication with the device.
+ *
+ * @debugfs_dentry: hookup for debugfs files.
+ * These have to be in a separate directory, a child of
+ * (wimax_dev->debugfs_dentry) so they can be removed when the
+ * module unloads, as we don't keep each dentry.

+ * - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ * COMMAND: implies a request from the host to the device requesting
+ * an action being performed. The device will reply with a
+ * message (with the same type as the command), status and
+ * no (TLV) payload. Execution of a command might cause
+ * events (of different type) to be sent later on as
+ * device's state changes.
+ *
+ * GET/SET: similar to COMMAND, but will not cause other
+ * EVENTs. The reply, in the case of GET, will contain
+ * TLVs with the requested information.
+ *
+ * EVENT: asynchronous messages sent from the device, maybe as a
+ * consequence of previous COMMANDs but disassociated from
+ * them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ * I2400M_MT_* Message types
+ * I2400M_MS_* Message status (for replies, events)
+ * i2400m_tlv_* TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.
