/**

|
Connect a class of devices using the platform Boot Manager policy.
|
|
|
|
The ConnectDeviceClass() function allows the caller to request that the Boot
|
|
Manager connect a class of devices.
|
|
|
|
If Class is EFI_BOOT_MANAGER_POLICY_CONSOLE_GUID then the Boot Manager will
|
|
use platform policy to connect consoles. Some platforms may restrict the
|
|
number of consoles connected as they attempt to fast boot, and calling
|
|
ConnectDeviceClass() with a Class value of EFI_BOOT_MANAGER_POLICY_CONSOLE_GUID
|
|
must connect the set of consoles that follow the Boot Manager platform policy,
|
|
and the EFI_SIMPLE_TEXT_INPUT_PROTOCOL, EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL, and
|
|
the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL are produced on the connected handles.
|
|
The Boot Manager may restrict which consoles get connect due to platform policy,
|
|
for example a security policy may require that a given console is not connected.
|
|
|
|
If Class is EFI_BOOT_MANAGER_POLICY_NETWORK_GUID then the Boot Manager will
|
|
connect the protocols the platforms supports for UEFI general purpose network
|
|
applications on one or more handles. If more than one network controller is
|
|
available a platform will connect, one, many, or all of the networks based
|
|
on platform policy. Connecting UEFI networking protocols, like EFI_DHCP4_PROTOCOL,
|
|
does not establish connections on the network. The UEFI general purpose network
|
|
application that called ConnectDeviceClass() may need to use the published
|
|
protocols to establish the network connection. The Boot Manager can optionally
|
|
have a policy to establish a network connection.
|
|
|
|
If Class is EFI_BOOT_MANAGER_POLICY_CONNECT_ALL_GUID then the Boot Manager
|
|
will connect all UEFI drivers using the UEFI Boot Service
|
|
EFI_BOOT_SERVICES.ConnectController(). If the Boot Manager has policy
|
|
associated with connect all UEFI drivers this policy will be used.
|
|
|
|
A platform can also define platform specific Class values as a properly generated
|
|
EFI_GUID would never conflict with this specification.
|
|
|
|
@param[in] This A pointer to the EFI_BOOT_MANAGER_POLICY_PROTOCOL instance.
|
|
@param[in] Class A pointer to an EFI_GUID that represents a class of devices
|
|
that will be connected using the Boot Mangers platform policy.
|
|
|
|
@retval EFI_SUCCESS At least one devices of the Class was connected.
|
|
@retval EFI_DEVICE_ERROR Devices were not connected due to an error.
|
|
@retval EFI_NOT_FOUND The Class is not supported by the platform.
|
|
@retval EFI_UNSUPPORTED The current TPL is not TPL_APPLICATION.
