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