4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Tests to see if this driver supports a given controller. If a child device is provided,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync it tests to see if this driver supports creating a handle for the specified child device.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function checks to see if the driver specified by This supports the device specified by
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ControllerHandle. Drivers typically use the device path attached to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ControllerHandle and/or the services from the bus I/O abstraction attached to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ControllerHandle to determine if the driver supports ControllerHandle. This function
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync may be called many times during platform initialization. In order to reduce boot times, the tests
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync performed by this function must be very small and take as little time as possible to execute. This
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync function must not change the state of any hardware devices, and this function must be aware that the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync device specified by ControllerHandle may already be managed by the same driver or a
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync different driver. This function must match its calls to AllocatePages() with FreePages(),
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Since ControllerHandle may have been previously started by the same driver, if a protocol is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync already in the opened state, then it must not be closed with CloseProtocol(). This is required
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync to guarantee the state of ControllerHandle is not modified by this function.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] ControllerHandle The handle of the controller to test. This handle
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync must support a protocol interface that supplies
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync an I/O abstraction to the driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync parameter is ignored by device drivers, and is optional for bus
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync drivers. For bus drivers, if this parameter is not NULL, then
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the bus driver must determine if the bus controller specified
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync by ControllerHandle and the child controller specified
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync by RemainingDevicePath are both supported by this
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync bus driver.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync RemainingDevicePath is supported by the driver specified by This.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_ALREADY_STARTED The device specified by ControllerHandle and
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync RemainingDevicePath is already managed by the driver
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync specified by This.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_ACCESS_DENIED The device specified by ControllerHandle and
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync RemainingDevicePath is already managed by a different
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync driver or an application that requires exclusive access.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath OPTIONAL
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Starts a device controller or a bus controller.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The Start() function is designed to be invoked from the EFI boot service ConnectController().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync As a result, much of the error checking on the parameters to Start() has been moved into this
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync common boot service. It is legal to call Start() from other locations,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync but the following calling restrictions must be followed or the system behavior will not be deterministic.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 1. ControllerHandle must be a valid EFI_HANDLE.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 2. If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync EFI_DEVICE_PATH_PROTOCOL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 3. Prior to calling Start(), the Supported() function for the driver specified by This must
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync have been called with the same calling parameters, and Supported() must have returned EFI_SUCCESS.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] ControllerHandle The handle of the controller to start. This handle
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync must support a protocol interface that supplies
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync an I/O abstraction to the driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync parameter is ignored by device drivers, and is optional for bus
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync drivers. For a bus driver, if this parameter is NULL, then handles
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync for all the children of Controller are created by this driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If this parameter is not NULL and the first Device Path Node is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync not the End of Device Path Node, then only the handle for the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync child device specified by the first Device Path Node of
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync RemainingDevicePath is created by this driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If the first Device Path Node of RemainingDevicePath is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the End of Device Path Node, no child handle is created by this
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The device was started.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_DEVICE_ERROR The device could not be started due to a device error. Currently not implemented.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_OUT_OF_RESOURCES The request could not be completed due to a lack of resources.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval Others The driver failed to start the device.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath OPTIONAL
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Stops a device controller or a bus controller.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The Stop() function is designed to be invoked from the EFI boot service DisconnectController().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync As a result, much of the error checking on the parameters to Stop() has been moved
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync into this common boot service. It is legal to call Stop() from other locations,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync but the following calling restrictions must be followed or the system behavior will not be deterministic.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync same driver's Start() function.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync EFI_HANDLE. In addition, all of these handles must have been created in this driver's
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Start() function, and the Start() function must have called OpenProtocol() on
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] ControllerHandle A handle to the device being stopped. The handle must
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync support a bus specific I/O protocol for the driver
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync to use to stop the device.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync if NumberOfChildren is 0.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The device was stopped.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_DEVICE_ERROR The device could not be stopped due to a device error.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function retrieves the user readable name of a driver in the form of a
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Unicode string. If the driver specified by This has a user readable name in
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the language specified by Language, then a pointer to the driver name is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync by This does not support the language specified by Language,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync then EFI_UNSUPPORTED is returned.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
