- Runs diagnostics on a controller.\r
-\r
- @param This A pointer to the EFI_DRIVER_DIAGNOSTICS_PROTOCOL\r
- instance.\r
- @param ControllerHandle The handle of the controller to run diagnostics on.\r
- @param 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\r
- controllers.\r
- @param DiagnosticType Indicates type of diagnostics to perform on the\r
- controller specified by ControllerHandle and ChildHandle.\r
- See "Related Definitions" for the list of supported\r
- types.\r
- @param 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\r
- SupportedLanguages. The number of languages supported by\r
- a driver is up to the driver writer.\r
- @param ErrorType A GUID that defines the format of the data returned in\r
- Buffer.\r
- @param BufferSize The size, in bytes, of the data returned in Buffer.\r
- @param 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

- type of diagnostic specified by DiagnosticType.\r
- @retval EFI_UNSUPPORTED The driver specified by This does not support the\r
