- Routine Description:\r
- Runs diagnostics on a controller.\r
-\r
- Arguments:\r
- This - A pointer to the EFI_DRIVER_DIAGNOSTICS_PROTOCOL instance.\r
- ControllerHandle - The handle of the controller to run diagnostics on.\r
- ChildHandle - The handle of the child controller to run diagnostics on\r
- This is an optional parameter that may be NULL. It will\r
- be NULL for device drivers. It will also be NULL for a\r
- bus drivers that wish to run diagnostics on the bus\r
- controller. It will not be NULL for a bus driver that\r
- wishes to run diagnostics on one of its child controllers.\r
- DiagnosticType - Indicates type of diagnostics to perform on the controller\r
- specified by ControllerHandle and ChildHandle. See\r
- "Related Definitions" for the list of supported types.\r
- Language - A pointer to a three character ISO 639-2 language\r
- identifier. This is the language in which the optional\r
- error message should be returned in Buffer, and it must\r
- match one of the languages specified in SupportedLanguages.\r
- The number of languages supported by a driver is up to\r
- the driver writer.\r
- ErrorType - A GUID that defines the format of the data returned in\r
- Buffer.\r
- BufferSize - The size, in bytes, of the data returned in Buffer.\r
- Buffer - A buffer that contains a Null-terminated Unicode string\r
- plus some additional data whose format is defined by\r
- ErrorType. Buffer is allocated by this function with\r
- AllocatePool(), and it is the caller's responsibility\r
- to free it with a call to FreePool().\r
-\r
- Returns:\r
- EFI_SUCCESS - The controller specified by ControllerHandle and\r
- ChildHandle passed the diagnostic.\r
- EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.\r
- EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid\r
- EFI_HANDLE.\r
- EFI_INVALID_PARAMETER - Language is NULL.\r
- EFI_INVALID_PARAMETER - ErrorType is NULL.\r
- EFI_INVALID_PARAMETER - BufferType is NULL.\r
- EFI_INVALID_PARAMETER - Buffer is NULL.\r
- EFI_UNSUPPORTED - The driver specified by This does not support\r
- running diagnostics for the controller specified\r
- by ControllerHandle and ChildHandle.\r
- EFI_UNSUPPORTED - The driver specified by This does not support the\r
- type of diagnostic specified by DiagnosticType.\r
- EFI_UNSUPPORTED - The driver specified by This does not support the\r
- language specified by Language.\r
- EFI_OUT_OF_RESOURCES - There are not enough resources available to complete\r
- the diagnostics.\r
- EFI_OUT_OF_RESOURCES - There are not enough resources available to return\r
- the status information in ErrorType, BufferSize,\r
- and Buffer.\r
- EFI_DEVICE_ERROR - The controller specified by ControllerHandle and\r
- ChildHandle did not pass the diagnostic.\r
