Merge with old docs. * * * The Virtual USB component glues USB devices and host controllers together. * The VUSB takes the form of a PDM driver which is attached to the HCI. USB * devices are created by, attached to, and managed by the VUSB roothub. The * VUSB also exposes an interface which is used by Main to attach and detach * proxied USB devices. * * * @section sec_dev_vusb_urb The Life of an URB * * The URB is created when the HCI calls the roothub (VUSB) method pfnNewUrb. * VUSB has a pool of URBs, if no free URBs are available a new one is * allocated. The returned URB starts life in the ALLOCATED state and all * fields are initialized with sensible defaults. * * The HCI then copies any request data into the URB if it's an host2dev * transfer. It then submits the URB by calling the pfnSubmitUrb roothub * method. * * pfnSubmitUrb will start by checking if it knows the device address, and if * it doesn't the URB is completed with a device-not-ready error. When the * device address is known to it, action is taken based on the kind of * transfer it is. There are four kinds of transfers: 1. control, 2. bulk, * 3. interrupt, and 4. isochronous. In either case something eventually ends * up being submitted to the device. * * * If an URB fails submitting, may or may not be completed. This depends on * heuristics in some cases and on the kind of failure in others. If * pfnSubmitUrb returns a failure, the HCI should retry submitting it at a * later time. If pfnSubmitUrb returns success the URB is submitted, and it * can even been completed. * * The URB is in the IN_FLIGHT state from the time it's successfully submitted * and till it's reaped or cancelled. * * When an URB transfer or in some case submit failure occurs, the pfnXferError * callback of the HCI is consulted about what to do. If pfnXferError indicates * that the URB should be retried, pfnSubmitUrb will fail. If it indicates that * it should fail, the URB will be completed. * * Completing an URB means that the URB status is set and the HCI * pfnXferCompletion callback is invoked with the URB. The HCI is the supposed * to report the transfer status to the guest OS. After completion the URB * is freed and returned to the pool, unless it was cancelled. If it was * cancelled it will have to await reaping before it's actually freed. * * * @subsection subsec_dev_vusb_urb_ctrl Control * * The control transfer is the most complex one, from VUSB's point of view, * with its three stages and being bi-directional. A control transfer starts * with a SETUP packet containing the request description and two basic * parameters. It is followed by zero or more DATA packets which either picks * up incoming data (dev2host) or supplies the request data (host2dev). This * can then be followed by a STATUS packet which gets the status of the whole * transfer. * * What makes the control transfer complicated is that for a host2dev request * the URB is assembled from the SETUP and DATA stage, and for a dev2host * request the returned data must be kept around for the DATA stage. For both * transfer directions the status of the transfer has to be kept around for * the STATUS stage. * * To complicate matters further, VUSB must intercept and in some cases emulate * some of the standard requests in order to keep the virtual device state * correct and provide the correct virtualization of a device. * * @subsection subsec_dev_vusb_urb_bulk Bulk and Interrupt * * The bulk and interrupt transfer types are relativly simple compared to the * control transfer. VUSB is not inspecting the request content or anything, * but passes it down the device. * * @subsection subsec_dev_vusb_urb_isoc Isochronous * * This kind of transfers hasn't yet been implemented. * */ /** @page pg_dev_vusb_old VUSB - Virtual USB Core * * The virtual USB core is controlled by the roothub and the underlying HCI * emulator, it is responsible for device addressing, managing configurations, * interfaces and endpoints, assembling and splitting multi-part control * messages and in general acts as a middle layer between the USB device * emulation code and USB HCI emulation code. * * All USB devices are represented by a struct vusb_dev. This structure * contains things like the device state, device address, all the configuration * descriptors, the currently selected configuration and a mapping between * endpoint addresses and endpoint descriptors. * * Each vusb_dev also has a pointer to a vusb_dev_ops structure which serves as * the virtual method table and includes a virtual constructor and destructor. * After a vusb_dev is created it may be attached to a hub device such as a * roothub (using vusbHubAttach). Although each hub structure has cPorts * and cDevices fields, it is the responsibility of the hub device to allocate * a free port for the new device. * * Devices can chose one of two interfaces for dealing with requests, the * synchronous interface or the asynchronous interface. The synchronous * interface is much simpler and ought to be used for devices which are * unlikely to sleep for long periods in order to serve requests. The * asynchronous interface on the other hand is more difficult to use but is * useful for the USB proxy or if one were to write a mass storage device * emulator. Currently the synchronous interface only supports control and bulk * endpoints and is no longer used by anything. * * In order to use the asynchronous interface, the queue_urb, cancel_urb and * pfnUrbReap fields must be set in the devices vusb_dev_ops structure. The * queue_urb method is used to submit a request to a device without blocking, * it returns 1 if successful and 0 on any kind of failure. A successfully * queued URB is completed when the pfnUrbReap method returns it. Each function * address is reference counted so that pfnUrbReap will only be called if there * are URBs outstanding. For a roothub to reap an URB from any one of it's * devices, the vusbRhReapAsyncUrbs() function is used. * * There are four types of messages an URB may contain: * -# Control - represents a single packet of a multi-packet control * transfer, these are only really used by the host controller to * submit the parts to the usb core. * -# Message - the usb core assembles multiple control transfers in * to single message transfers. In this case the data buffer * contains the setup packet in little endian followed by the full * buffer. In the case of an host-to-device control message, the * message packet is created when the STATUS transfer is seen. In * the case of device-to-host messages, the message packet is * created after the SETUP transfer is seen. Also, certain control * requests never go the real device and get handled synchronously. * -# Bulk - Currently the only endpoint type that does error checking * and endpoint halting. * -# Interrupt - The only non-periodic type supported. * * Hubs are special cases of devices, they have a number of downstream ports * that other devices can be attached to and removed from. * * After a device has been attached (vusbHubAttach): * -# The hub attach method is called, which sends a hub status * change message to the OS. * -# The OS resets the device, and it appears on the default * address with it's config 0 selected (a pseudo-config that * contains only 1 interface with 1 endpoint - the default * message pipe). * -# The OS assigns the device a new address and selects an * appropriate config. * -# The device is ready. * * After a device has been detached (vusbDevDetach): * -# All pending URBs are cancelled. * -# The devices address is unassigned. * -# The hub detach method is called which signals the OS * of the status change. * -# The OS unlinks the ED's for that device. * * A device can also request detachment from within its own methods by * calling vusbDevUnplugged(). * * Roothubs are responsible for driving the whole system, they are special * cases of hubs and as such implement attach and detach methods, each one * is described by a struct vusb_roothub. Once a roothub has submitted an * URB to the USB core, a number of callbacks to the roothub are required * for when the URB completes, since the roothub typically wants to inform * the OS when transfers are completed. * * There are four callbacks to be concerned with: * -# prepare - This is called after the URB is successfully queued. * -# completion - This is called after the URB completed. * -# error - This is called if the URB errored, some systems have * automatic resubmission of failed requests, so this callback * should keep track of the error count and return 1 if the count * is above the number of allowed resubmissions. * -# halt_ep - This is called after errors on bulk pipes in order * to halt the pipe. * */ /********************************************************************************************************************************* * Header Files * *********************************************************************************************************************************/ #define LOG_GROUP LOG_GROUP_DRV_VUSB #include #include #include #include #include #include #include #include #include #include #include #include #include "VUSBInternal.h" #include "VBoxDD.h" #define VUSB_ROOTHUB_SAVED_STATE_VERSION 1 /** * Data used for reattaching devices on a state load. */ typedef struct VUSBROOTHUBLOAD { /** Timer used once after state load to inform the guest about new devices. * We do this to be sure the guest get any disconnect / reconnect on the * same port. */ TMTIMERHANDLE hTimer;
