It will 62 be NULL for device drivers. It will also be NULL for a 63 bus drivers that wish to run diagnostics on the bus 64 controller. It will not be NULL for a bus driver that 65 wishes to run diagnostics on one of its child controllers. 66 DiagnosticType - Indicates type of diagnostics to perform on the controller 67 specified by ControllerHandle and ChildHandle. See 68 "Related Definitions" for the list of supported types. 69 Language - A pointer to a NULL-terminated ASCII string array indicating 70 the language. This is the language in which the optional 71 error message should be returned in Buffer, and it must 72 match one of the languages specified in SupportedLanguages. 73 The number of languages supported by a driver is up to 74 the driver writer. Language is specified in RFC 3066 75 language code format. 76 ErrorType - A GUID that defines the format of the data returned in 77 Buffer. 78 BufferSize - The size, in bytes, of the data returned in Buffer. 79 Buffer - A buffer that contains a Null-terminated Unicode string 80 plus some additional data whose format is defined by 81 ErrorType. Buffer is allocated by this function with 82 AllocatePool(), and it is the caller's responsibility 83 to free it with a call to FreePool(). 84 85 Returns: 86 EFI_SUCCESS - The controller specified by ControllerHandle and 87 ChildHandle passed the diagnostic. 88 EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE. 89 EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid 90 EFI_HANDLE. 91 EFI_INVALID_PARAMETER - Language is NULL. 92 EFI_INVALID_PARAMETER - ErrorType is NULL. 93 EFI_INVALID_PARAMETER - BufferType is NULL. 94 EFI_INVALID_PARAMETER - Buffer is NULL. 95 EFI_UNSUPPORTED - The driver specified by This does not support 96 running diagnostics for the controller specified 97 by ControllerHandle and ChildHandle. 98 EFI_UNSUPPORTED - The driver specified by This does not support the 99 type of diagnostic specified by DiagnosticType. 100 EFI_UNSUPPORTED - The driver specified by This does not support the 101 language specified by Language. 102 EFI_OUT_OF_RESOURCES - There are not enough resources available to complete 103 the diagnostics. 104 EFI_OUT_OF_RESOURCES - There are not enough resources available to return 105 the status information in ErrorType, BufferSize, 106 and Buffer. 107 EFI_DEVICE_ERROR - The controller specified by ControllerHandle and 108 ChildHandle did not pass the diagnostic. 109 110 --*/ 111 112 // 113 // Interface structure for the Driver Diagnostics Protocol 114 // 115 struct _EFI_DRIVER_DIAGNOSTICS2_PROTOCOL { 116 EFI_DRIVER_DIAGNOSTICS2_RUN_DIAGNOSTICS RunDiagnostics; 117 CHAR8 *SupportedLanguages; 118 }; 119 120 /*++ 121 122 Protocol Description: 123 Used to perform diagnostics on a controller that an EFI Driver is managing. 124 125 Parameters: 126 RunDiagnostics - Runs diagnostics on a controller. 127 SupportedLanguages - A Null-terminated ASCII string that contains one or more 128 RFC 3066 language codes.
