+ACPI Debug Output
+=================
The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
output. This document describes how to use this facility.
Compile-time configuration
---------------------------
+==========================
ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG. If this config
option is turned off, the debug messages are not even built into the
kernel.
Boot- and run-time configuration
