ACPICA Trace Facility
trace_method_name
The AML method name that the user wants to trace
Copyright (C) 2015, Intel Corporation
Author: Lv Zheng <lv.zheng@intel.com>
trace_debug_layer
The temporary debug_layer used when tracing the method.
Using 0xffffffff by default if it is 0.
trace_debug_level
The temporary debug_level used when tracing the method.
Using 0x00ffffff by default if it is 0.
Abstract:
trace_state
This document describes the functions and the interfaces of the method
tracing facility.
1. Functionalities and usage examples:
ACPICA provides method tracing capability. And two functions are
currently implemented using this capability.
A. Log reducer
ACPICA subsystem provides debugging outputs when CONFIG_ACPI_DEBUG is
enabled. The debugging messages which are deployed via
ACPI_DEBUG_PRINT() macro can be reduced at 2 levels - per-component
level (known as debug layer, configured via
/sys/module/acpi/parameters/debug_layer) and per-type level (known as
debug level, configured via /sys/module/acpi/parameters/debug_level).
But when the particular layer/level is applied to the control method
evaluations, the quantity of the debugging outputs may still be too
large to be put into the kernel log buffer. The idea thus is worked out
to only enable the particular debug layer/level (normally more detailed)
logs when the control method evaluation is started, and disable the
detailed logging when the control method evaluation is stopped.
The following command examples illustrate the usage of the "log reducer"
functionality:
a. Filter out the debug layer/level matched logs when control methods
are being evaluated:
# cd /sys/module/acpi/parameters
# echo "0xXXXXXXXX" > trace_debug_layer
# echo "0xYYYYYYYY" > trace_debug_level
# echo "enable" > trace_state
b. Filter out the debug layer/level matched logs when the specified
control method is being evaluated:
# cd /sys/module/acpi/parameters
# echo "0xXXXXXXXX" > trace_debug_layer
# echo "0xYYYYYYYY" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "method" > /sys/module/acpi/parameters/trace_state
c. Filter out the debug layer/level matched logs when the specified
control method is being evaluated for the first time:
# cd /sys/module/acpi/parameters
# echo "0xXXXXXXXX" > trace_debug_layer
# echo "0xYYYYYYYY" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "method-once" > /sys/module/acpi/parameters/trace_state
Where:
0xXXXXXXXX/0xYYYYYYYY: Refer to Documentation/acpi/debug.txt for
possible debug layer/level masking values.
\PPPP.AAAA.TTTT.HHHH: Full path of a control method that can be found
in the ACPI namespace. It needn't be an entry
of a control method evaluation.
B. AML tracer
There are special log entries added by the method tracing facility at
the "trace points" the AML interpreter starts/stops to execute a control
method, or an AML opcode. Note that the format of the log entries are
subject to change:
[ 0.186427] exdebug-0398 ex_trace_point : Method Begin [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.
[ 0.186630] exdebug-0398 ex_trace_point : Opcode Begin [0xf5905c88:If] execution.

[ 0.187010] exdebug-0398 ex_trace_point : Opcode Begin [0xf5905a20:-NamePath-] execution.
[ 0.187214] exdebug-0398 ex_trace_point : Opcode End [0xf5905a20:-NamePath-] execution.
[ 0.187407] exdebug-0398 ex_trace_point : Opcode Begin [0xf5905f60:One] execution.
[ 0.187594] exdebug-0398 ex_trace_point : Opcode End [0xf5905f60:One] execution.
[ 0.187789] exdebug-0398 ex_trace_point : Opcode End [0xf5905cc0:LEqual] execution.
[ 0.187980] exdebug-0398 ex_trace_point : Opcode Begin [0xf5905cc0:Return] execution.
[ 0.188146] exdebug-0398 ex_trace_point : Opcode Begin [0xf5905f60:One] execution.
[ 0.188334] exdebug-0398 ex_trace_point : Opcode End [0xf5905f60:One] execution.
[ 0.188524] exdebug-0398 ex_trace_point : Opcode End [0xf5905cc0:Return] execution.
[ 0.188712] exdebug-0398 ex_trace_point : Opcode End [0xf5905c88:If] execution.
[ 0.188903] exdebug-0398 ex_trace_point : Method End [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.
Developers can utilize these special log entries to track the AML
interpretion, thus can aid issue debugging and performance tuning. Note
that, as the "AML tracer" logs are implemented via ACPI_DEBUG_PRINT()
macro, CONFIG_ACPI_DEBUG is also required to be enabled for enabling
"AML tracer" logs.
The following command examples illustrate the usage of the "AML tracer"
functionality:
a. Filter out the method start/stop "AML tracer" logs when control
methods are being evaluated:
# cd /sys/module/acpi/parameters
# echo "0x80" > trace_debug_layer
# echo "0x10" > trace_debug_level
# echo "enable" > trace_state
b. Filter out the method start/stop "AML tracer" when the specified
control method is being evaluated:
# cd /sys/module/acpi/parameters
# echo "0x80" > trace_debug_layer
# echo "0x10" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "method" > trace_state
c. Filter out the method start/stop "AML tracer" logs when the specified
control method is being evaluated for the first time:
# cd /sys/module/acpi/parameters
# echo "0x80" > trace_debug_layer
# echo "0x10" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "method-once" > trace_state
d. Filter out the method/opcode start/stop "AML tracer" when the
specified control method is being evaluated:
# cd /sys/module/acpi/parameters
# echo "0x80" > trace_debug_layer
# echo "0x10" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "opcode" > trace_state
e. Filter out the method/opcode start/stop "AML tracer" when the
specified control method is being evaluated for the first time:
# cd /sys/module/acpi/parameters
# echo "0x80" > trace_debug_layer
# echo "0x10" > trace_debug_level
# echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
# echo "opcode-opcode" > trace_state
Note that all above method tracing facility related module parameters can
be used as the boot parameters, for example:
acpi.trace_debug_layer=0x80 acpi.trace_debug_level=0x10 \
acpi.trace_method_name=\_SB.LID0._LID acpi.trace_state=opcode-once
2. Interface descriptions:
All method tracing functions can be configured via ACPI module
parameters that are accessible at /sys/module/acpi/parameters/:
trace_method_name
The full path of the AML method that the user wants to trace.
Note that the full path shouldn't contain the trailing "_"s in its
name segments but may contain "\" to form an absolute path.
trace_debug_layer
The temporary debug_layer used when the tracing feature is enabled.
Using ACPI_EXECUTER (0x80) by default, which is the debug_layer
used to match all "AML tracer" logs.
trace_debug_level
The temporary debug_level used when the tracing feature is enabled.
Using ACPI_LV_TRACE_POINT (0x10) by default, which is the
debug_level used to match all "AML tracer" logs.
trace_state
The status of the tracing feature.
"enabled" means this feature is enabled
and the AML method is traced every time it's executed.
"1" means this feature is enabled and the AML method
will only be traced during the next execution.
"disabled" means this feature is disabled.
Users can enable/disable this debug tracing feature by
"echo string > /sys/module/acpi/parameters/trace_state".
"string" should be one of "enable", "disable" and "1".
Users can enable/disable this debug tracing feature by executing
the following command:
# echo string > /sys/module/acpi/parameters/trace_state
Where "string" should be one of the followings:
"disable"
Disable the method tracing feature.
"enable"
Enable the method tracing feature.
ACPICA debugging messages matching
"trace_debug_layer/trace_debug_level" during any method
execution will be logged.
"method"
Enable the method tracing feature.
ACPICA debugging messages matching
"trace_debug_layer/trace_debug_level" during method execution
of "trace_method_name" will be logged.
"method-once"
Enable the method tracing feature.
ACPICA debugging messages matching
"trace_debug_layer/trace_debug_level" during method execution
of "trace_method_name" will be logged only once.
"opcode"
Enable the method tracing feature.
ACPICA debugging messages matching
"trace_debug_layer/trace_debug_level" during method/opcode
execution of "trace_method_name" will be logged.
"opcode-once"
Enable the method tracing feature.
ACPICA debugging messages matching
"trace_debug_layer/trace_debug_level" during method/opcode
execution of "trace_method_name" will be logged only once.
Note that, the difference between the "enable" and other feature
enabling options are:
1. When "enable" is specified, since
"trace_debug_layer/trace_debug_level" shall apply to all control
method evaluations, after configuring "trace_state" to "enable",
"trace_method_name" will be reset to NULL.
2. When "method/opcode" is specified, if
"trace_method_name" is NULL when "trace_state" is configured to
these options, the "trace_debug_layer/trace_debug_level" will
apply to all control method evaluations.

Note that this direct-complete procedure applies even if the device is
disabled for runtime PM; only the runtime-PM status matters. It follows
that if a device has system-sleep callbacks but does not support runtime
PM, then its prepare callback must never return a positive value. This
is because all devices are initially set to runtime-suspended with
runtime PM disabled.
