|

| 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.

|---|
