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 "usbdevs.h" -#include <dev/usb2/include/usb2_standard.h> -#include <dev/usb2/include/usb2_mfunc.h> -#include <dev/usb2/include/usb2_error.h> - -#define USB_DEBUG_VAR usb2_debug - -#include <dev/usb2/core/usb2_core.h> -#include <dev/usb2/core/usb2_debug.h> -#include <dev/usb2/core/usb2_parse.h> -#include <dev/usb2/core/usb2_lookup.h> -#include <dev/usb2/core/usb2_util.h> -#include <dev/usb2/core/usb2_busdma.h> -#include <dev/usb2/core/usb2_process.h> -#include <dev/usb2/core/usb2_transfer.h> - -#include <sys/mbuf.h> -#include <sys/taskqueue.h> - -#include <netgraph/ng_message.h> -#include <netgraph/netgraph.h> -#include <netgraph/ng_parse.h> -#include <netgraph/bluetooth/include/ng_bluetooth.h> -#include <netgraph/bluetooth/include/ng_hci.h> -#include <netgraph/bluetooth/include/ng_ubt.h> - -#include <dev/usb2/bluetooth/usb2_bluetooth.h> -#include <dev/usb2/bluetooth/ng_ubt2_var.h> - -static int ubt_modevent(module_t, int, void *);
