31 | * @todo read thru this and correct typos. Merge with old docs.
|
---|
32 | *
|
---|
33 | *
|
---|
34 | * The Virtual USB component glues USB devices and host controllers together.
|
---|
35 | * The VUSB takes the form of a PDM driver which is attached to the HCI. USB
|
---|
36 | * devices are created by, attached to, and managed by the VUSB roothub. The
|
---|
37 | * VUSB also exposes an interface which is used by Main to attach and detach
|
---|
38 | * proxied USB devices.
|
---|
39 | *
|
---|
40 | *
|
---|
41 | * @section sec_dev_vusb_urb The Life of an URB
|
---|
42 | *
|
---|
43 | * The URB is created when the HCI calls the roothub (VUSB) method pfnNewUrb.
|
---|
44 | * VUSB has a pool of URBs, if no free URBs are available a new one is
|
---|
45 | * allocated. The returned URB starts life in the ALLOCATED state and all
|
---|
46 | * fields are initialized with sensible defaults.
|
---|
47 | *
|
---|
48 | * The HCI then copies any request data into the URB if it's an host2dev
|
---|
49 | * transfer. It then submits the URB by calling the pfnSubmitUrb roothub
|
---|
50 | * method.
|
---|
51 | *
|
---|
52 | * pfnSubmitUrb will start by checking if it knows the device address, and if
|
---|
53 | * it doesn't the URB is completed with a device-not-ready error. When the
|
---|
54 | * device address is known to it, action is taken based on the kind of
|
---|
55 | * transfer it is. There are four kinds of transfers: 1. control, 2. bulk,
|
---|
56 | * 3. interrupt, and 4. isochronous. In either case something eventually ends
|
---|
57 | * up being submitted to the device.
|
---|
58 | *
|
---|
59 | *
|
---|
60 | * If an URB fails submitting, may or may not be completed. This depends on
|
---|
61 | * heuristics in some cases and on the kind of failure in others. If
|
---|
62 | * pfnSubmitUrb returns a failure, the HCI should retry submitting it at a
|
---|
63 | * later time. If pfnSubmitUrb returns success the URB is submitted, and it
|
---|
64 | * can even been completed.
|
---|
65 | *
|
---|
66 | * The URB is in the IN_FLIGHT state from the time it's successfully submitted
|
---|
67 | * and till it's reaped or cancelled.
|
---|
68 | *
|
---|
69 | * When an URB transfer or in some case submit failure occurs, the pfnXferError
|
---|
70 | * callback of the HCI is consulted about what to do. If pfnXferError indicates
|
---|
71 | * that the URB should be retried, pfnSubmitUrb will fail. If it indicates that
|
---|
72 | * it should fail, the URB will be completed.
|
---|
73 | *
|
---|
74 | * Completing an URB means that the URB status is set and the HCI
|
---|
75 | * pfnXferCompletion callback is invoked with the URB. The HCI is the supposed
|
---|
76 | * to report the transfer status to the guest OS. After completion the URB
|
---|
77 | * is freed and returned to the pool, unless it was cancelled. If it was
|
---|
78 | * cancelled it will have to await reaping before it's actually freed.
|
---|
79 | *
|
---|
80 | *
|
---|
81 | * @subsection subsec_dev_vusb_urb_ctrl Control
|
---|
82 | *
|
---|
83 | * The control transfer is the most complex one, from VUSB's point of view,
|
---|
84 | * with its three stages and being bi-directional. A control transfer starts
|
---|
85 | * with a SETUP packet containing the request description and two basic
|
---|
86 | * parameters. It is followed by zero or more DATA packets which either picks
|
---|
87 | * up incoming data (dev2host) or supplies the request data (host2dev). This
|
---|
88 | * can then be followed by a STATUS packet which gets the status of the whole
|
---|
89 | * transfer.
|
---|
90 | *
|
---|
91 | * What makes the control transfer complicated is that for a host2dev request
|
---|
92 | * the URB is assembled from the SETUP and DATA stage, and for a dev2host
|
---|
93 | * request the returned data must be kept around for the DATA stage. For both
|
---|
94 | * transfer directions the status of the transfer has to be kept around for
|
---|
95 | * the STATUS stage.
|
---|
96 | *
|
---|
97 | * To complicate matters further, VUSB must intercept and in some cases emulate
|
---|
98 | * some of the standard requests in order to keep the virtual device state
|
---|
99 | * correct and provide the correct virtualization of a device.
|
---|
100 | *
|
---|
101 | * @subsection subsec_dev_vusb_urb_bulk Bulk and Interrupt
|
---|
102 | *
|
---|
103 | * The bulk and interrupt transfer types are relativly simple compared to the
|
---|
104 | * control transfer. VUSB is not inspecting the request content or anything,
|
---|
105 | * but passes it down the device.
|
---|
106 | *
|
---|
107 | * @subsection subsec_dev_vusb_urb_isoc Isochronous
|
---|
108 | *
|
---|
109 | * This kind of transfers hasn't yet been implemented.

114 | /** @page pg_dev_vusb_old VUSB - Virtual USB Core
|
---|
115 | *
|
---|
116 | * The virtual USB core is controlled by the roothub and the underlying HCI
|
---|
117 | * emulator, it is responsible for device addressing, managing configurations,
|
---|
118 | * interfaces and endpoints, assembling and splitting multi-part control
|
---|
119 | * messages and in general acts as a middle layer between the USB device
|
---|
120 | * emulation code and USB HCI emulation code.
|
---|
121 | *
|
---|
122 | * All USB devices are represented by a struct vusb_dev. This structure
|
---|
123 | * contains things like the device state, device address, all the configuration
|
---|
124 | * descriptors, the currently selected configuration and a mapping between
|
---|
125 | * endpoint addresses and endpoint descriptors.
|
---|
126 | *
|
---|
127 | * Each vusb_dev also has a pointer to a vusb_dev_ops structure which serves as
|
---|
128 | * the virtual method table and includes a virtual constructor and destructor.
|
---|
129 | * After a vusb_dev is created it may be attached to a hub device such as a
|
---|
130 | * roothub (using vusbHubAttach). Although each hub structure has cPorts
|
---|
131 | * and cDevices fields, it is the responsibility of the hub device to allocate
|
---|
132 | * a free port for the new device.
|
---|
133 | *
|
---|
134 | * Devices can chose one of two interfaces for dealing with requests, the
|
---|
135 | * synchronous interface or the asynchronous interface. The synchronous
|
---|
136 | * interface is much simpler and ought to be used for devices which are
|
---|
137 | * unlikely to sleep for long periods in order to serve requests. The
|
---|
138 | * asynchronous interface on the other hand is more difficult to use but is
|
---|
139 | * useful for the USB proxy or if one were to write a mass storage device
|
---|
140 | * emulator. Currently the synchronous interface only supports control and bulk
|
---|
141 | * endpoints and is no longer used by anything.
|
---|
142 | *
|
---|
143 | * In order to use the asynchronous interface, the queue_urb, cancel_urb and
|
---|
144 | * pfnUrbReap fields must be set in the devices vusb_dev_ops structure. The
|
---|
145 | * queue_urb method is used to submit a request to a device without blocking,
|
---|
146 | * it returns 1 if successful and 0 on any kind of failure. A successfully
|
---|
147 | * queued URB is completed when the pfnUrbReap method returns it. Each function
|
---|
148 | * address is reference counted so that pfnUrbReap will only be called if there
|
---|
149 | * are URBs outstanding. For a roothub to reap an URB from any one of it's
|
---|
150 | * devices, the vusbRhReapAsyncUrbs() function is used.
|
---|
151 | *
|
---|
152 | * There are four types of messages an URB may contain:
|
---|
153 | * -# Control - represents a single packet of a multi-packet control
|
---|
154 | * transfer, these are only really used by the host controller to
|
---|
155 | * submit the parts to the usb core.
|
---|
156 | * -# Message - the usb core assembles multiple control transfers in
|
---|
157 | * to single message transfers. In this case the data buffer
|
---|
158 | * contains the setup packet in little endian followed by the full
|
---|
159 | * buffer. In the case of an host-to-device control message, the
|
---|
160 | * message packet is created when the STATUS transfer is seen. In
|
---|
161 | * the case of device-to-host messages, the message packet is
|
---|
162 | * created after the SETUP transfer is seen. Also, certain control
|
---|
163 | * requests never go the real device and get handled synchronously.
|
---|
164 | * -# Bulk - Currently the only endpoint type that does error checking
|
---|
165 | * and endpoint halting.
|
---|
166 | * -# Interrupt - The only non-periodic type supported.
|
---|
167 | *
|
---|
168 | * Hubs are special cases of devices, they have a number of downstream ports
|
---|
169 | * that other devices can be attached to and removed from.
|
---|
170 | *
|
---|
171 | * After a device has been attached (vusbHubAttach):
|
---|
172 | * -# The hub attach method is called, which sends a hub status
|
---|
173 | * change message to the OS.
|
---|
174 | * -# The OS resets the device, and it appears on the default
|
---|
175 | * address with it's config 0 selected (a pseudo-config that
|
---|
176 | * contains only 1 interface with 1 endpoint - the default
|
---|
177 | * message pipe).
|
---|
178 | * -# The OS assigns the device a new address and selects an
|
---|
179 | * appropriate config.
|
---|
180 | * -# The device is ready.
|
---|
181 | *
|
---|
182 | * After a device has been detached (vusbDevDetach):
|
---|
183 | * -# All pending URBs are cancelled.
|
---|
184 | * -# The devices address is unassigned.
|
---|
185 | * -# The hub detach method is called which signals the OS
|
---|
186 | * of the status change.
|
---|
187 | * -# The OS unlinks the ED's for that device.
|
---|
188 | *
|
---|
189 | * A device can also request detachment from within its own methods by
|
---|
190 | * calling vusbDevUnplugged().
|
---|
191 | *
|
---|
192 | * Roothubs are responsible for driving the whole system, they are special
|
---|
193 | * cases of hubs and as such implement attach and detach methods, each one
|
---|
194 | * is described by a struct vusb_roothub. Once a roothub has submitted an
|
---|
195 | * URB to the USB core, a number of callbacks to the roothub are required
|
---|
196 | * for when the URB completes, since the roothub typically wants to inform
|
---|
197 | * the OS when transfers are completed.
|
---|
198 | *
|
---|
199 | * There are four callbacks to be concerned with:
|
---|
200 | * -# prepare - This is called after the URB is successfully queued.
|
---|
201 | * -# completion - This is called after the URB completed.
|
---|
202 | * -# error - This is called if the URB errored, some systems have
|
---|
203 | * automatic resubmission of failed requests, so this callback
|
---|
204 | * should keep track of the error count and return 1 if the count
|
---|
205 | * is above the number of allowed resubmissions.
|
---|
206 | * -# halt_ep - This is called after errors on bulk pipes in order
|
---|
207 | * to halt the pipe.
