It implements a Bluetooth USB transport layer as per chapter H2 of the Bluetooth Specification Book v1.1. A new node is created when a supported USB device is plugged in. .Pp The node has a single hook called .Dv hook . Incoming bytes received on the device are re-assembled into HCI frames (according to the length). Full HCI frames are sent out on the hook. The node will add a HCI frame indicator if the device did not send it. HCI frames received on .Dv hook are transmitted out. The node will drop the HCI frame indicator unless the device requires it to be present. .Sh HARDWARE The .Nm driver supports all Bluetooth USB devices that conform with the Bluetooth specification v1.1, including: .Pp .Bl -bullet -compact .It 3Com 3CREB96 .It AIPTEK BR0R02 .It EPoX BT-DG02 .It Mitsumi Bluetooth USB adapter .It MSI MS-6967 .It TDK Bluetooth USB adapter +.It +Broadcom Bluetooth USB adapter .El .Sh HOOKS This node type supports the following hooks: .Bl -tag -width indent .It Dv hook single HCI frame contained in a single .Vt mbuf structure. .El .Sh CONTROL MESSAGES This node type supports the generic control messages, plus the following: .Bl -tag -width indent .It Dv NGM_UBT_NODE_GET_DEBUG Returns an integer containing the current debug level for the node. .It Dv NGM_UBT_NODE_SET_DEBUG This command takes an integer argument and sets the current debug level for the node. .It Dv NGM_UBT_NODE_GET_QLEN This command takes a parameter that specifies the queue number and returns the current maximal length of the queue for the node. .It Dv NGM_UBT_NODE_SET_QLEN This command takes two parameters that specify the queue number and the maximum length of the queue and sets the maximal length of the queue for the node. .It Dv NGM_UBT_NODE_GET_STAT Returns various statistic information for the node, such as: number of bytes (frames) sent, number of bytes (frames) received and number of input (output) errors. .It Dv NGM_UBT_NODE_RESET_STAT Reset all statistic counters to zero. .El .Sh SHUTDOWN This node shuts down when the corresponding USB device is un-plugged. .Sh SEE ALSO .Xr netgraph 4 , .Xr ugen 4 , .Xr usb 4 , .Xr ngctl 8 .Sh HISTORY The .Nm ubt node type was implemented in .Fx 5.0 . .Sh AUTHORS .An Maksim Yevmenkin Aq m_evmenkin@yahoo.com .Sh BUGS Isochronous USB transfers are broken. This means that the USB device will not be able to transfer SCO data (voice). USB interrupt transfers are implemented as bulk-in transfers (not really a bug).

On one side it is * a USB device driver and on the other it is a Netgraph node. This * driver will *NOT* create traditional /dev/ enties, only Netgraph * node. * * NOTE ON LOCKS USED: ng_ubt2 drives uses 2 locks (mutexes) * * 1) sc_if_mtx - lock for device's interface #0 and #1. This lock is used * by USB for any USB request going over device's interface #0 and #1, * i.e. interrupt, control, bulk and isoc. transfers. * * 2) sc_ng_mtx - this lock is used to protect shared (between USB, Netgraph * and Taskqueue) data, such as outgoing mbuf queues, task flags and hook * pointer. This lock *SHOULD NOT* be grabbed for a long time. In fact, * think of it as a spin lock. * * NOTE ON LOCKING STRATEGY: ng_ubt2 driver operates in 3 different contexts. * * 1) USB context. This is where all the USB related stuff happens. All * callbacks run in this context. All callbacks are called (by USB) with * appropriate interface lock held. It is (generally) allowed to grab * any additional locks. * * 2) Netgraph context. This is where all the Netgraph related stuff happens. * Since we mark node as WRITER, the Netgraph node will be "locked" (from * Netgraph point of view). Any variable that is only modified from the * Netgraph context does not require any additonal locking. It is generally * *NOT* allowed to grab *ANY* additional locks. Whatever you do, *DO NOT* * grab any lock in the Netgraph context that could cause de-scheduling of * the Netgraph thread for significant amount of time. In fact, the only * lock that is allowed in the Netgraph context is the sc_ng_mtx lock. * Also make sure that any code that is called from the Netgraph context * follows the rule above. * * 3) Taskqueue context. This is where ubt_task runs. Since we are generally * NOT allowed to grab any lock that could cause de-scheduling in the * Netgraph context, and, USB requires us to grab interface lock before * doing things with transfers, it is safer to transition from the Netgraph * context to the Taskqueue context before we can call into USB subsystem. * * So, to put everything together, the rules are as follows. * It is OK to call from the USB context or the Taskqueue context into * the Netgraph context (i.e. call NG_SEND_xxx functions). In other words * it is allowed to call into the Netgraph context with locks held. * Is it *NOT* OK to call from the Netgraph context into the USB context, * because USB requires us to grab interface locks, and, it is safer to * avoid it. So, to make things safer we set task flags to indicate which * actions we want to perform and schedule ubt_task which would run in the * Taskqueue context. * Is is OK to call from the Taskqueue context into the USB context, * and, ubt_task does just that (i.e. grabs appropriate interface locks * before calling into USB). * Access to the outgoing queues, task flags and hook pointer is * controlled by the sc_ng_mtx lock. It is an unavoidable evil. Again, * sc_ng_mtx should really be a spin lock (and it is very likely to an * equivalent of spin lock due to adaptive nature of FreeBSD mutexes). * All USB callbacks accept softc pointer as a private data. USB ensures * that this pointer is valid. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "usbdevs.h" #include #include #include #define USB_DEBUG_VAR usb_debug #include #include #include #include #include #include #include #include #include #include #include static int ubt_modevent(module_t, int, void *);
