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
--------------------------------

When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
you're interested in. At boot-time, use the acpi.debug_layer and
acpi.debug_level kernel command line options. After boot, you can use the
debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
the debug messages.

debug_layer (component)
-----------------------

The "debug_layer" is a mask that selects components of interest, e.g., a
specific driver or part of the ACPI interpreter. To build the debug_layer
bitmask, look for the "#define _COMPONENT" in an ACPI source file.

You can set the debug_layer mask at boot-time using the acpi.debug_layer
command line argument, and you can change it after boot by writing values
to /sys/module/acpi/parameters/debug_layer.

The possible components are defined in include/acpi/acoutput.h and
include/acpi/acpi_drivers.h. Reading /sys/module/acpi/parameters/debug_layer
shows the supported mask values, currently these:

ACPI_UTILITIES 0x00000001

ACPI_EVENTS 0x00000004

ACPI_MEMORY_DEVICE_COMPONENT 0x08000000
ACPI_VIDEO_COMPONENT 0x10000000
ACPI_PROCESSOR_COMPONENT 0x20000000

debug_level
-----------

The "debug_level" is a mask that selects different types of messages, e.g.,
those related to initialization, method execution, informational messages, etc.
To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
statement.

The ACPI interpreter uses several different levels, but the Linux
ACPI core and ACPI drivers generally only use ACPI_LV_INFO.

You can set the debug_level mask at boot-time using the acpi.debug_level
command line argument, and you can change it after boot by writing values
to /sys/module/acpi/parameters/debug_level.

The possible levels are defined in include/acpi/acoutput.h. Reading
/sys/module/acpi/parameters/debug_level shows the supported mask values,
currently these:

ACPI_LV_INIT 0x00000001
ACPI_LV_DEBUG_OBJECT 0x00000002
ACPI_LV_INFO 0x00000004
ACPI_LV_INIT_NAMES 0x00000020

ACPI_LV_EXEC 0x00000200
ACPI_LV_NAMES 0x00000400
ACPI_LV_OPREGION 0x00000800

ACPI_LV_FULL_TABLES 0x40000000
ACPI_LV_EVENTS 0x80000000

Examples
--------

For example, drivers/acpi/bus.c contains this:

#define _COMPONENT ACPI_BUS_COMPONENT
...
ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Device insertion detected\n"));

To turn on this message, set the ACPI_BUS_COMPONENT bit in acpi.debug_layer
and the ACPI_LV_INFO bit in acpi.debug_level. (The ACPI_DEBUG_PRINT
statement uses ACPI_DB_INFO, which is macro based on the ACPI_LV_INFO
definition.)

Enable all AML "Debug" output (stores to the Debug object while interpreting
AML) during boot:

acpi.debug_layer=0xffffffff acpi.debug_level=0x2

Enable PCI and PCI interrupt routing debug messages:

acpi.debug_layer=0x400000 acpi.debug_level=0x4

Enable all ACPI hardware-related messages:

acpi.debug_layer=0x2 acpi.debug_level=0xffffffff

Enable all ACPI_DB_INFO messages after boot:

# echo 0x4 > /sys/module/acpi/parameters/debug_level

Show all valid component values:

# cat /sys/module/acpi/parameters/debug_layer
