35 * NOTE: ng_ubt2 driver has a split personality. On one side it is
36 * a USB device driver and on the other it is a Netgraph node. This
37 * driver will *NOT* create traditional /dev/ enties, only Netgraph
40 * NOTE ON LOCKS USED: ng_ubt2 drives uses 2 locks (mutexes)
42 * 1) sc_if_mtx - lock for device's interface #0 and #1. This lock is used
43 * by USB for any USB request going over device's interface #0 and #1,
44 * i.e. interrupt, control, bulk and isoc. transfers.
46 * 2) sc_ng_mtx - this lock is used to protect shared (between USB, Netgraph
47 * and Taskqueue) data, such as outgoing mbuf queues, task flags and hook
48 * pointer. This lock *SHOULD NOT* be grabbed for a long time. In fact,
49 * think of it as a spin lock.
51 * NOTE ON LOCKING STRATEGY: ng_ubt2 driver operates in 3 different contexts.
53 * 1) USB context. This is where all the USB related stuff happens. All
54 * callbacks run in this context. All callbacks are called (by USB) with
55 * appropriate interface lock held. It is (generally) allowed to grab
56 * any additional locks.
58 * 2) Netgraph context. This is where all the Netgraph related stuff happens.
59 * Since we mark node as WRITER, the Netgraph node will be "locked" (from
60 * Netgraph point of view). Any variable that is only modified from the
61 * Netgraph context does not require any additonal locking. It is generally
62 * *NOT* allowed to grab *ANY* additional locks. Whatever you do, *DO NOT*
63 * grab any lock in the Netgraph context that could cause de-scheduling of
64 * the Netgraph thread for significant amount of time. In fact, the only
65 * lock that is allowed in the Netgraph context is the sc_ng_mtx lock.
66 * Also make sure that any code that is called from the Netgraph context
67 * follows the rule above.
69 * 3) Taskqueue context. This is where ubt_task runs. Since we are generally
70 * NOT allowed to grab any lock that could cause de-scheduling in the
71 * Netgraph context, and, USB requires us to grab interface lock before
72 * doing things with transfers, it is safer to transition from the Netgraph
73 * context to the Taskqueue context before we can call into USB subsystem.
75 * So, to put everything together, the rules are as follows.
76 * It is OK to call from the USB context or the Taskqueue context into
77 * the Netgraph context (i.e. call NG_SEND_xxx functions). In other words
78 * it is allowed to call into the Netgraph context with locks held.
79 * Is it *NOT* OK to call from the Netgraph context into the USB context,
80 * because USB requires us to grab interface locks, and, it is safer to
81 * avoid it. So, to make things safer we set task flags to indicate which
82 * actions we want to perform and schedule ubt_task which would run in the
84 * Is is OK to call from the Taskqueue context into the USB context,
85 * and, ubt_task does just that (i.e. grabs appropriate interface locks
86 * before calling into USB).
87 * Access to the outgoing queues, task flags and hook pointer is
88 * controlled by the sc_ng_mtx lock. It is an unavoidable evil. Again,
89 * sc_ng_mtx should really be a spin lock (and it is very likely to an
90 * equivalent of spin lock due to adaptive nature of FreeBSD mutexes).
91 * All USB callbacks accept softc pointer as a private data. USB ensures
92 * that this pointer is valid.
