62 | * DESCRIPTION: Handles stores to the AML Debug Object. For example: | |
63 | * Store(INT1, Debug) | |
64 | * | |
65 | * This function is not compiled if ACPI_NO_ERROR_MESSAGES is set. | |
66 | * | |
67 | * This function is only enabled if acpi_gbl_enable_aml_debug_object is set, or | |
68 | * if ACPI_LV_DEBUG_OBJECT is set in the acpi_dbg_level. Thus, in the normal | |
69 | * operational case, stores to the debug object are ignored but can be easily | |
70 | * enabled if necessary. | |
