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. + */ + +#ifndef __LINUX__WIMAX__I2400M_H__ +#define __LINUX__WIMAX__I2400M_H__ + +#include + + +/* + * Host Device Interface (HDI) common to all busses + */ + +/* Boot-mode (firmware upload mode) commands */ + +/* Header for the firmware file */ +struct i2400m_bcf_hdr { + __le32 module_type; + __le32 header_len; + __le32 header_version; + __le32 module_id; + __le32 module_vendor; + __le32 date; /* BCD YYYMMDD */ + __le32 size; + __le32 key_size; /* in dwords */ + __le32 modulus_size; /* in dwords */ + __le32 exponent_size; /* in dwords */ + __u8 reserved[88]; +} __attribute__ ((packed)); + +/* Boot mode opcodes */ +enum i2400m_brh_opcode { + I2400M_BRH_READ = 1, + I2400M_BRH_WRITE = 2, + I2400M_BRH_JUMP = 3, + I2400M_BRH_SIGNED_JUMP = 8, + I2400M_BRH_HASH_PAYLOAD_ONLY = 9, +}; + +/* Boot mode command masks and stuff */ +enum i2400m_brh { + I2400M_BRH_SIGNATURE = 0xcbbc0000, + I2400M_BRH_SIGNATURE_MASK = 0xffff0000, + I2400M_BRH_SIGNATURE_SHIFT = 16, + I2400M_BRH_OPCODE_MASK = 0x0000000f, + I2400M_BRH_RESPONSE_MASK = 0x000000f0, + I2400M_BRH_RESPONSE_SHIFT = 4, + I2400M_BRH_DIRECT_ACCESS = 0x00000400, + I2400M_BRH_RESPONSE_REQUIRED = 0x00000200, + I2400M_BRH_USE_CHECKSUM = 0x00000100, +}; + + +/* Constants for bcf->module_id */ +enum i2400m_bcf_mod_id { + /* Firmware file carries its own pokes -- pokes are a set of + * magical values that have to be written in certain memory + * addresses to get the device up and ready for firmware + * download when it is in non-signed boot mode. */ + I2400M_BCF_MOD_ID_POKES = 0x000000001, +}; + + +/** + * i2400m_bootrom_header - Header for a boot-mode command + * + * @cmd: the above command descriptor + * @target_addr: where on the device memory should the action be performed. + * @data_size: for read/write, amount of data to be read/written + * @block_checksum: checksum value (if applicable) + * @payload: the beginning of data attached to this header + */ +struct i2400m_bootrom_header { + __le32 command; /* Compose with enum i2400_brh */ + __le32 target_addr; + __le32 data_size; + __le32 block_checksum; + char payload[0]; +} __attribute__ ((packed)); + + +/* + * Data / control protocol + */ + +/* Packet types for the host-device interface */ +enum i2400m_pt { + I2400M_PT_DATA = 0, + I2400M_PT_CTRL, + I2400M_PT_TRACE, /* For device debug */ + I2400M_PT_RESET_WARM, /* device reset */ + I2400M_PT_RESET_COLD, /* USB[transport] reset, like reconnect */ + I2400M_PT_ILLEGAL +}; + + +/* + * Payload for a data packet + * + * This is prefixed to each and every outgoing DATA type. + */ +struct i2400m_pl_data_hdr { + __le32 reserved; +} __attribute__((packed)); + + +/* Misc constants */ +enum { + I2400M_PL_PAD = 16, /* Payload data size alignment */ + I2400M_PL_SIZE_MAX = 0x3EFF, + I2400M_MAX_PLS_IN_MSG = 60, + /* protocol barkers: sync sequences; for notifications they + * are sent in groups of four. */ + I2400M_H2D_PREVIEW_BARKER = 0xcafe900d, + I2400M_COLD_RESET_BARKER = 0xc01dc01d, + I2400M_WARM_RESET_BARKER = 0x50f750f7, + I2400M_NBOOT_BARKER = 0xdeadbeef, + I2400M_SBOOT_BARKER = 0x0ff1c1a1, + I2400M_ACK_BARKER = 0xfeedbabe, + I2400M_D2H_MSG_BARKER = 0xbeefbabe, +}; + + +/* + * Hardware payload descriptor + * + * Bitfields encoded in a struct to enforce typing semantics. + * + * Look in rx.c and tx.c for a full description of the format. + */ +struct i2400m_pld { + __le32 val; +} __attribute__ ((packed)); + +#define I2400M_PLD_SIZE_MASK 0x00003fff +#define I2400M_PLD_TYPE_SHIFT 16 +#define I2400M_PLD_TYPE_MASK 0x000f0000 + +/* + * Header for a TX message or RX message + * + * @barker: preamble + * @size: used for management of the FIFO queue buffer; before + * sending, this is converted to be a real preamble.

This API affects the control plane; the + * data plane is accessed via the network stack (netdev). + * + * Parts of the WiMAX stack API and notifications are exported to + * user space via Generic Netlink. In user space, libwimax (part of + * the wimax-tools package) provides a shim layer for accessing those + * calls. + * + * The API is standarized for all WiMAX devices and different drivers + * implement the backend support for it. However, device-specific + * messaging pipes are provided that can be used to issue commands and + * receive notifications in free form. + * + * Currently the messaging pipes are the only means of control as it + * is not known (due to the lack of more devices in the market) what + * will be a good abstraction layer. Expect this to change as more + * devices show in the market. This API is designed to be growable in + * order to address this problem. + * + * USAGE + * + * Embed a `struct wimax_dev` at the beginning of the the device's + * private structure, initialize and register it. For details, see + * `struct wimax_dev`s documentation. + * + * Once this is done, wimax-tools's libwimaxll can be used to + * communicate with the driver from user space. You user space + * application does not have to forcibily use libwimaxll and can talk + * the generic netlink protocol directly if desired. + * + * Remember this is a very low level API that will to provide all of + * WiMAX features. Other daemons and services running in user space + * are the expected clients of it. They offer a higher level API that + * applications should use (an example of this is the Intel's WiMAX + * Network Service for the i2400m). + * + * DESIGN + * + * Although not set on final stone, this very basic interface is + * mostly completed. Remember this is meant to grow as new common + * operations are decided upon. New operations will be added to the + * interface, intent being on keeping backwards compatibility as much + * as possible. + * + * This layer implements a set of calls to control a WiMAX device, + * exposing a frontend to the rest of the kernel and user space (via + * generic netlink) and a backend implementation in the driver through + * function pointers. + * + * WiMAX devices have a state, and a kernel-only API allows the + * drivers to manipulate that state. State transitions are atomic, and + * only some of them are allowed (see `enum wimax_st`). + * + * Most API calls will set the state automatically; in most cases + * drivers have to only report state changes due to external + * conditions. + * + * All API operations are 'atomic', serialized thorough a mutex in the + * `struct wimax_dev`. + * + * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK + * + * The API is exported to user space using generic netlink (other + * methods can be added as needed). + * + * There is a Generic Netlink Family named "WiMAX", where interfaces + * supporting the WiMAX interface receive commands and broadcast their + * signals over a multicast group named "msg". + * + * Mapping to the source/destination interface is done by an interface + * index attribute. + * + * For user-to-kernel traffic (commands) we use a function call + * marshalling mechanism, where a message X with attributes A, B, C + * sent from user space to kernel space means executing the WiMAX API + * call wimax_X(A, B, C), sending the results back as a message. + * + * Kernel-to-user (notifications or signals) communication is sent + * over multicast groups. This allows to have multiple applications + * monitoring them. + * + * Each command/signal gets assigned it's own attribute policy. This + * way the validator will verify that all the attributes in there are + * only the ones that should be for each command/signal. Thing of an + * attribute mapping to a type+argumentname for each command/signal. + * + * If we had a single policy for *all* commands/signals, after running + * the validator we'd have to check "does this attribute belong in + * here"? for each one. It can be done manually, but it's just easier + * to have the validator do that job with multiple policies. As well, + * it makes it easier to later expand each command/signal signature + * without affecting others and keeping the namespace more or less + * sane. Not that it is too complicated, but it makes it even easier. + * + * No state information is maintained in the kernel for each user + * space connection (the connection is stateless). + * + * TESTING FOR THE INTERFACE AND VERSIONING + * + * If network interface X is a WiMAX device, there will be a Generic + * Netlink family named "WiMAX X" and the device will present a + * "wimax" directory in it's network sysfs directory + * (/sys/class/net/DEVICE/wimax) [used by HAL]. + * + * The inexistence of any of these means the device does not support + * this WiMAX API. + * + * By querying the generic netlink controller, versioning information + * and the multicast groups available can be found. Applications using + * the interface can either rely on that or use the generic netlink + * controller to figure out which generic netlink commands/signals are + * supported. + * + * NOTE: this versioning is a last resort to avoid hard + * incompatibilities. It is the intention of the design of this + * stack not to introduce backward incompatible changes. + * + * The version code has to fit in one byte (restrictions imposed by + * generic netlink); we use `version / 10` for the major version and + * `version % 10` for the minor. This gives 9 minors for each major + * and 25 majors. + * + * The version change protocol is as follow: + * + * - Major versions: needs to be increased if an existing message/API + * call is changed or removed. Doesn't need to be changed if a new + * message is added. + * + * - Minor version: needs to be increased if new messages/API calls are + * being added or some other consideration that doesn't impact the + * user-kernel interface too much (like some kind of bug fix) and + * that is kind of left up in the air to common sense. + * + * User space code should not try to work if the major version it was + * compiled for differs from what the kernel offers. As well, if the + * minor version of the kernel interface is lower than the one user + * space is expecting (the one it was compiled for), the kernel + * might be missing API calls; user space shall be ready to handle + * said condition. Use the generic netlink controller operations to + * find which ones are supported and which not. + * + * libwimaxll:wimaxll_open() takes care of checking versions. + * + * THE OPERATIONS: + * + * Each operation is defined in its on file (drivers/net/wimax/op-*.c) + * for clarity. The parts needed for an operation are: + * + * - a function pointer in `struct wimax_dev`: optional, as the + * operation might be implemented by the stack and not by the + * driver. + * + * All function pointers are named wimax_dev->op_*(), and drivers + * must implement them except where noted otherwise. + * + * - When exported to user space, a `struct nla_policy` to define the + * attributes of the generic netlink command and a `struct genl_ops` + * to define the operation. + * + * All the declarations for the operation codes (WIMAX_GNL_OP_) + * and generic netlink attributes (WIMAX_GNL__*) are declared in + * include/linux/wimax.h; this file is intended to be cloned by user + * space to gain access to those declarations. + * + * A few caveats to remember: + * + * - Need to define attribute numbers starting in 1; otherwise it + * fails. + * + * - the `struct genl_family` requires a maximum attribute id; when + * defining the `struct nla_policy` for each message, it has to have + * an array size of WIMAX_GNL_ATTR_MAX+1. + * + * THE PIPE INTERFACE: + * + * This interface is kept intentionally simple. The driver can send + * and receive free-form messages to/from user space through a + * pipe. See drivers/net/wimax/op-msg.c for details. + * + * The kernel-to-user messages are sent with + * wimax_msg(). user-to-kernel messages are delivered via + * wimax_dev->op_msg_from_user(). + * + * RFKILL: + * + * RFKILL support is built into the wimax_dev layer; the driver just + * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in + * the hardware or software RF kill switches. When the stack wants to + * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(), + * which the driver implements. + * + * User space can set the software RF Kill switch by calling + * wimax_rfkill(). + * + * The code for now only supports devices that don't require polling; + * If the device needs to be polled, create a self-rearming delayed + * work struct for polling or look into adding polled support to the + * WiMAX stack. + * + * When initializing the hardware (_probe), after calling + * wimax_dev_add(), query the device for it's RF Kill switches status + * and feed it back to the WiMAX stack using + * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always + * report it as ON. + * + * NOTE: the wimax stack uses an inverted terminology to that of the + * RFKILL subsystem: + * + * - ON: radio is ON, RFKILL is DISABLED or OFF. + * - OFF: radio is OFF, RFKILL is ENABLED or ON. + * + * MISCELLANEOUS OPS: + * + * wimax_reset() can be used to reset the device to power on state; by + * default it issues a warm reset that maintains the same device + * node. If that is not possible, it falls back to a cold reset + * (device reconnect). The driver implements the backend to this + * through wimax_dev->op_reset(). + */ + +#ifndef __NET__WIMAX_H__ +#define __NET__WIMAX_H__ +#ifdef __KERNEL__ + +#include +#include +#include + +struct net_device; +struct genl_info; +struct wimax_dev; +struct input_dev; + +/** + * struct wimax_dev - Generic WiMAX device + * + * @net_dev: [fill] Pointer to the &struct net_device this WiMAX + * device implements. + * + * @op_msg_from_user: [fill] Driver-specific operation to + * handle a raw message from user space to the driver.

Embed a &struct wimax_dev at *the beginning* the network + * device structure so that netdev_priv() points to it. + * + * 2. memset() it to zero + * + * 3. Initialize with wimax_dev_init(). This will leave the WiMAX + * device in the %__WIMAX_ST_NULL state. + * + * 4. Fill all the fields marked with [fill]; once called + * wimax_dev_add(), those fields CANNOT be modified. + * + * 5. Call wimax_dev_add() *after* registering the network + * device. This will leave the WiMAX device in the %WIMAX_ST_DOWN + * state. + * Protect the driver's net_device->open() against succeeding if + * the wimax device state is lower than %WIMAX_ST_DOWN. + * + * 6. Select when the device is going to be turned on/initialized; + * for example, it could be initialized on 'ifconfig up' (when the + * netdev op 'open()' is called on the driver). + * + * When the device is initialized (at `ifconfig up` time, or right + * after calling wimax_dev_add() from _probe(), make sure the + * following steps are taken + * + * a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so + * some API calls that shouldn't work until the device is ready + * can be blocked. + * + * b. Initialize the device. Make sure to turn the SW radio switch + * off and move the device to state %WIMAX_ST_RADIO_OFF when + * done. When just initialized, a device should be left in RADIO + * OFF state until user space devices to turn it on. + * + * c. Query the device for the state of the hardware rfkill switch + * and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw() + * as needed. See below. + * + * wimax_dev_rm() undoes before unregistering the network device. Once + * wimax_dev_add() is called, the driver can get called on the + * wimax_dev->op_* function pointers + * + * CONCURRENCY: + * + * The stack provides a mutex for each device that will disallow API + * calls happening concurrently; thus, op calls into the driver + * through the wimax_dev->op*() function pointers will always be + * serialized and *never* concurrent. + * + * For locking, take wimax_dev->mutex is taken; (most) operations in + * the API have to check for wimax_dev_is_ready() to return 0 before + * continuing (this is done internally). + * + * REFERENCE COUNTING: + * + * The WiMAX device is reference counted by the associated network + * device. The only operation that can be used to reference the device + * is wimax_dev_get_by_genl_info(), and the reference it acquires has + * to be released with dev_put(wimax_dev->net_dev). + * + * RFKILL: + * + * At startup, both HW and SW radio switchess are assumed to be off. + * + * At initialization time [after calling wimax_dev_add()], have the + * driver query the device for the status of the software and hardware + * RF kill switches and call wimax_report_rfkill_hw() and + * wimax_rfkill_report_sw() to indicate their state.
