* FUNCTION: AcpiExDoDebugObject
|
|
*
|
|
* PARAMETERS: SourceDesc - Object to be output to "Debug Object"
|
|
* Level - Indentation level (used for packages)
|
|
* Index - Current package element, zero if not pkg
|
|
*
|
|
* RETURN: None
|

*
|
|
* DESCRIPTION: Handles stores to the AML Debug Object. For example:
|
|
* Store(INT1, Debug)
|
|
*
|
|
* This function is not compiled if ACPI_NO_ERROR_MESSAGES is set.
|
|
*
|
|
* This function is only enabled if AcpiGbl_EnableAmlDebugObject is set, or
|
|
* if ACPI_LV_DEBUG_OBJECT is set in the AcpiDbgLevel. Thus, in the normal
|
|
* operational case, stores to the debug object are ignored but can be easily
|
|
* enabled if necessary.
