Some platforms may restrict the 84 number of consoles connected as they attempt to fast boot, and calling 85 ConnectDeviceClass() with a Class value of EFI_BOOT_MANAGER_POLICY_CONSOLE_GUID 86 must connect the set of consoles that follow the Boot Manager platform policy, 87 and the EFI_SIMPLE_TEXT_INPUT_PROTOCOL, EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL, and 88 the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL are produced on the connected handles. 89 The Boot Manager may restrict which consoles get connect due to platform policy, 90 for example a security policy may require that a given console is not connected. 91 92 If Class is EFI_BOOT_MANAGER_POLICY_NETWORK_GUID then the Boot Manager will 93 connect the protocols the platforms supports for UEFI general purpose network 94 applications on one or more handles. If more than one network controller is 95 available a platform will connect, one, many, or all of the networks based 96 on platform policy. Connecting UEFI networking protocols, like EFI_DHCP4_PROTOCOL, 97 does not establish connections on the network. The UEFI general purpose network 98 application that called ConnectDeviceClass() may need to use the published 99 protocols to establish the network connection. The Boot Manager can optionally 100 have a policy to establish a network connection. 101 102 If Class is EFI_BOOT_MANAGER_POLICY_CONNECT_ALL_GUID then the Boot Manager 103 will connect all UEFI drivers using the UEFI Boot Service 104 EFI_BOOT_SERVICES.ConnectController(). If the Boot Manager has policy 105 associated with connect all UEFI drivers this policy will be used. 106 107 A platform can also define platform specific Class values as a properly generated 108 EFI_GUID would never conflict with this specification. 109 110 @param[in] This A pointer to the EFI_BOOT_MANAGER_POLICY_PROTOCOL instance. 111 @param[in] Class A pointer to an EFI_GUID that represents a class of devices 112 that will be connected using the Boot Mangers platform policy. 113 114 @retval EFI_SUCCESS At least one devices of the Class was connected. 115 @retval EFI_DEVICE_ERROR Devices were not connected due to an error. 116 @retval EFI_NOT_FOUND The Class is not supported by the platform. 117 @retval EFI_UNSUPPORTED The current TPL is not TPL_APPLICATION. 118 **/ 119 typedef 120 EFI_STATUS 121 (EFIAPI *EFI_BOOT_MANAGER_POLICY_CONNECT_DEVICE_CLASS)( 122 IN EFI_BOOT_MANAGER_POLICY_PROTOCOL *This, 123 IN EFI_GUID *Class 124 ); 125 126 struct _EFI_BOOT_MANAGER_POLICY_PROTOCOL { 127 UINT64 Revision; 128 EFI_BOOT_MANAGER_POLICY_CONNECT_DEVICE_PATH ConnectDevicePath; 129 EFI_BOOT_MANAGER_POLICY_CONNECT_DEVICE_CLASS ConnectDeviceClass; 130 }; 131 132 extern EFI_GUID gEfiBootManagerPolicyProtocolGuid; 133 134 extern EFI_GUID gEfiBootManagerPolicyConsoleGuid; 135 extern EFI_GUID gEfiBootManagerPolicyNetworkGuid; 136 extern EFI_GUID gEfiBootManagerPolicyConnectAllGuid; 137 138 #endif 139
