20 *
21 * @todo read thru this and correct typos. Merge with old docs.
22 *
23 *
24 * The Virtual USB component glues USB devices and host controllers together.
25 * The VUSB takes the form of a PDM driver which is attached to the HCI. USB
26 * devices are created by, attached to, and managed by the VUSB roothub. The
27 * VUSB also exposes an interface which is used by Main to attach and detach
28 * proxied USB devices.
29 *
30 *
31 * @section sec_dev_vusb_urb The Life of an URB
32 *
33 * The URB is created when the HCI calls the roothub (VUSB) method pfnNewUrb.
34 * VUSB has a pool of URBs, if no free URBs are available a new one is
35 * allocated. The returned URB starts life in the ALLOCATED state and all
36 * fields are initialized with sensible defaults.
37 *
38 * The HCI then copies any request data into the URB if it's an host2dev
39 * transfer. It then submits the URB by calling the pfnSubmitUrb roothub
40 * method.
41 *
42 * pfnSubmitUrb will start by checking if it knows the device address, and if
43 * it doesn't the URB is completed with a device-not-ready error. When the
44 * device address is known to it, action is taken based on the kind of
45 * transfer it is. There are four kinds of transfers: 1. control, 2. bulk,
46 * 3. interrupt, and 4. isochronous. In either case something eventually ends
47 * up being submitted to the device.
48 *
49 *
50 * If an URB fails submitting, may or may not be completed. This depends on
51 * heuristics in some cases and on the kind of failure in others. If
52 * pfnSubmitUrb returns a failure, the HCI should retry submitting it at a
53 * later time. If pfnSubmitUrb returns success the URB is submitted, and it
54 * can even been completed.
55 *
56 * The URB is in the IN_FLIGHT state from the time it's successfully submitted
57 * and till it's reaped or cancelled.
58 *
59 * When an URB transfer or in some case submit failure occurs, the pfnXferError
60 * callback of the HCI is consulted about what to do. If pfnXferError indicates
61 * that the URB should be retried, pfnSubmitUrb will fail. If it indicates that
62 * it should fail, the URB will be completed.
63 *
64 * Completing an URB means that the URB status is set and the HCI
65 * pfnXferCompletion callback is invoked with the URB. The HCI is the supposed
66 * to report the transfer status to the guest OS. After completion the URB
67 * is freed and returned to the pool, unless it was cancelled. If it was
68 * cancelled it will have to await reaping before it's actually freed.
69 *
70 *
71 * @subsection subsec_dev_vusb_urb_ctrl Control
72 *
73 * The control transfer is the most complex one, from VUSB's point of view,
74 * with its three stages and being bi-directional. A control transfer starts
75 * with a SETUP packet containing the request description and two basic
76 * parameters. It is followed by zero or more DATA packets which either picks
77 * up incoming data (dev2host) or supplies the request data (host2dev). This
78 * can then be followed by a STATUS packet which gets the status of the whole
79 * transfer.
80 *
81 * What makes the control transfer complicated is that for a host2dev request
82 * the URB is assembled from the SETUP and DATA stage, and for a dev2host
83 * request the returned data must be kept around for the DATA stage. For both
84 * transfer directions the status of the transfer has to be kept around for
85 * the STATUS stage.
86 *
87 * To complicate matters further, VUSB must intercept and in some cases emulate
88 * some of the standard requests in order to keep the virtual device state
89 * correct and provide the correct virtualization of a device.
90 *
91 * @subsection subsec_dev_vusb_urb_bulk Bulk and Interrupt
92 *
93 * The bulk and interrupt transfer types are relativly simple compared to the
94 * control transfer. VUSB is not inspecting the request content or anything,
95 * but passes it down the device.
96 *
97 * @subsection subsec_dev_vusb_urb_bulk Isochronous
98 *
99 * This kind of transfers hasn't yet been implemented.

104/** @page pg_dev_vusb_old VUSB - Virtual USB Core
105 *
106 * The virtual USB core is controlled by the roothub and the underlying HCI
107 * emulator, it is responsible for device addressing, managing configurations,
108 * interfaces and endpoints, assembling and splitting multi-part control
109 * messages and in general acts as a middle layer between the USB device
110 * emulation code and USB HCI emulation code.
111 *
112 * All USB devices are represented by a struct vusb_dev. This structure
113 * contains things like the device state, device address, all the configuration
114 * descriptors, the currently selected configuration and a mapping between
115 * endpoint addresses and endpoint descriptors.
116 *
117 * Each vusb_dev also has a pointer to a vusb_dev_ops structure which serves as
118 * the virtual method table and includes a virtual constructor and destructor.
119 * After a vusb_dev is created it may be attached to a hub device such as a
120 * roothub (using vusbHubAttach). Although each hub structure has cPorts
121 * and cDevices fields, it is the responsibility of the hub device to allocate
122 * a free port for the new device.
123 *
124 * Devices can chose one of two interfaces for dealing with requests, the
125 * synchronous interface or the asynchronous interface. The synchronous
126 * interface is much simpler and ought to be used for devices which are
127 * unlikely to sleep for long periods in order to serve requests. The
128 * asynchronous interface on the other hand is more difficult to use but is
129 * useful for the USB proxy or if one were to write a mass storage device
130 * emulator. Currently the synchronous interface only supports control and bulk
131 * endpoints and is no longer used by anything.
132 *
133 * In order to use the asynchronous interface, the queue_urb, cancel_urb and
134 * pfnUrbReap fields must be set in the devices vusb_dev_ops structure. The
135 * queue_urb method is used to submit a request to a device without blocking,
136 * it returns 1 if successful and 0 on any kind of failure. A successfully
137 * queued URB is completed when the pfnUrbReap method returns it. Each function
138 * address is reference counted so that pfnUrbReap will only be called if there
139 * are URBs outstanding. For a roothub to reap an URB from any one of it's
140 * devices, the vusbRhReapAsyncUrbs() function is used.
141 *
142 * There are four types of messages an URB may contain:
143 * -# Control - represents a single packet of a multi-packet control
144 * transfer, these are only really used by the host controller to
145 * submit the parts to the usb core.
146 * -# Message - the usb core assembles multiple control transfers in
147 * to single message transfers. In this case the data buffer
148 * contains the setup packet in little endian followed by the full
149 * buffer. In the case of an host-to-device control message, the
150 * message packet is created when the STATUS transfer is seen. In
151 * the case of device-to-host messages, the message packet is
152 * created after the SETUP transfer is seen. Also, certain control
153 * requests never go the real device and get handled synchronously.
154 * -# Bulk - Currently the only endpoint type that does error checking
155 * and endpoint halting.
156 * -# Interrupt - The only non-periodic type supported.
157 *
158 * Hubs are special cases of devices, they have a number of downstream ports
159 * that other devices can be attached to and removed from.
160 *
161 * After a device has been attached (vusbHubAttach):
162 * -# The hub attach method is called, which sends a hub status
163 * change message to the OS.
164 * -# The OS resets the device, and it appears on the default
165 * address with it's config 0 selected (a pseudo-config that
166 * contains only 1 interface with 1 endpoint - the default
167 * message pipe).
168 * -# The OS assigns the device a new address and selects an
169 * appropriate config.
170 * -# The device is ready.
171 *
172 * After a device has been detached (vusbDevDetach):
173 * -# All pending URBs are cancelled.
174 * -# The devices address is unassigned.
175 * -# The hub detach method is called which signals the OS
176 * of the status change.
177 * -# The OS unlinks the ED's for that device.
178 *
179 * A device can also request detachment from within its own methods by
180 * calling vusbDevUnplugged().
181 *
182 * Roothubs are responsible for driving the whole system, they are special
183 * cases of hubs and as such implement attach and detach methods, each one
184 * is described by a struct vusb_roothub. Once a roothub has submitted an
185 * URB to the USB core, a number of callbacks to the roothub are required
186 * for when the URB completes, since the roothub typically wants to inform
187 * the OS when transfers are completed.
188 *
189 * There are four callbacks to be concerned with:
190 * -# prepare - This is called after the URB is successfully queued.
191 * -# completion - This is called after the URB completed.
192 * -# error - This is called if the URB errored, some systems have
193 * automatic resubmission of failed requests, so this callback
194 * should keep track of the error count and return 1 if the count
195 * is above the number of allowed resubmissions.
196 * -# halt_ep - This is called after errors on bulk pipes in order
197 * to halt the pipe.
