2 | UEFI DriverBinding Protocol is defined in UEFI specification.\r |
3 | \r | |
4 | This protocol is produced by every driver that follows the UEFI Driver Model, \r | |
5 | and it is the central component that allows drivers and controllers to be managed.\r | |

104 | @par Protocol Description:\r | |
105 | This protocol provides the services required to determine if a driver supports a given controller. \r | |
106 | If a controller is supported, then it also provides routines to start and stop the controller.\r | |
107 | \r | |
108 | @param Supported \r | |
109 | Tests to see if this driver supports a given controller. This service\r | |
110 | is called by the EFI boot service ConnectController(). In\r | |
111 | order to make drivers as small as possible, there are a few calling\r | |
112 | restrictions for this service. ConnectController() must\r | |
113 | follow these calling restrictions. If any other agent wishes to call\r | |
114 | Supported() it must also follow these calling restrictions.\r | |
115 | \r | |
116 | \r | |
117 | @param Start \r | |
118 | Starts a controller using this driver. This service is called by the\r | |
119 | EFI boot service ConnectController(). In order to make\r | |
120 | drivers as small as possible, there are a few calling restrictions for\r | |
121 | this service. ConnectController() must follow these\r | |
122 | calling restrictions. If any other agent wishes to call Start() it\r | |
123 | must also follow these calling restrictions. \r | |
124 | \r | |
125 | @param Stop \r | |
126 | Stops a controller using this driver. This service is called by the\r | |
127 | EFI boot service DisconnectController(). In order to\r | |
128 | make drivers as small as possible, there are a few calling\r | |
129 | restrictions for this service. DisconnectController()\r | |
130 | must follow these calling restrictions. If any other agent wishes\r | |
131 | to call Stop() it must also follow these calling restrictions.\r | |
132 | \r | |
133 | @param Version \r | |
134 | The version number of the UEFI driver that produced the\r | |
135 | EFI_DRIVER_BINDING_PROTOCOL. This field is used by\r | |
136 | the EFI boot service ConnectController() to determine\r | |
137 | the order that driver's Supported() service will be used when\r | |
138 | a controller needs to be started. EFI Driver Binding Protocol\r | |
139 | instances with higher Version values will be used before ones\r | |
140 | with lower Version values. The Version values of 0x0-\r | |
141 | 0x0f and 0xfffffff0-0xffffffff are reserved for\r | |
142 | platform/OEM specific drivers. The Version values of 0x10-\r | |
143 | 0xffffffef are reserved for IHV-developed drivers.\r | |
144 | \r | |
145 | @param ImageHandle \r | |
146 | The image handle of the UEFI driver that produced this instance\r | |
147 | of the EFI_DRIVER_BINDING_PROTOCOL.\r | |
148 | \r | |
149 | @param DriverBindingHandle\r | |
150 | The handle on which this instance of the\r | |
151 | EFI_DRIVER_BINDING_PROTOCOL is installed. In most\r | |
152 | cases, this is the same handle as ImageHandle. However, for\r | |
153 | UEFI drivers that produce more than one instance of the\r | |
154 | EFI_DRIVER_BINDING_PROTOCOL, this value may not be\r | |
155 | the same as ImageHandle.\r | |
