ACPICA commit d4a53a396fe5d384425251b0257f8d125bbed617 Especially for use of the Index operator. For buffers and strings, only output the actual byte pointed to by the index. For packages, only print the package element decoded by the index.

* FUNCTION: acpi_ex_do_debug_object
|
|
*
|
|
* PARAMETERS: source_desc - Object to be output to "Debug Object"
|
|
* level - Indentation level (used for packages)
|
|
* index - Current package element, zero if not pkg

*
|

|
|
* 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 acpi_gbl_enable_aml_debug_object is set, or
|
|
* if ACPI_LV_DEBUG_OBJECT is set in the acpi_dbg_level. Thus, in the normal
|
|
* operational case, stores to the debug object are ignored but can be easily
|
|
* enabled if necessary.
