The AML Debugger
|

||||

|
||||
This document describes the usage of the AML debugger embedded in the Linux
|
||||
kernel.
|
||||
|
||||
1. Build the debugger
|
||||
|
||||
The following kernel configuration items are required to enable the AML
|
||||
debugger interface from the Linux kernel:
|
||||
|
||||
CONFIG_ACPI_DEBUGGER=y
|
||||
CONFIG_ACPI_DEBUGGER_USER=m
|
||||
|
||||
The userspace utilities can be built from the kernel source tree using
|
||||
the following commands:
|
||||
|
||||
$ cd tools
|
||||
$ make acpi
|
||||
|
||||
The resultant userspace tool binary is then located at:
|
||||
|
||||
tools/power/acpi/acpidbg
|
||||
|
||||
It can be installed to system directories by running "make install" (as a
|
||||
sufficiently privileged user).
|
||||
|
||||
2. Start the userspace debugger interface
|
||||
|
||||
After booting the kernel with the debugger built-in, the debugger can be
|
||||
started by using the following commands:
|
||||
|
||||
# mount -t debugfs none /sys/kernel/debug
|
||||
# modprobe acpi_dbg
|
||||
# tools/power/acpi/acpidbg
|
||||
|
||||
That spawns the interactive AML debugger environment where you can execute
|
||||
debugger commands.
|
||||
|
||||
The commands are documented in the "ACPICA Overview and Programmer Reference"
|
||||
that can be downloaded from
|
||||
|
||||
https://acpica.org/documentation
|
||||
|
||||
The detailed debugger commands reference is located in Chapter 12 "ACPICA
|
||||
Debugger Reference". The "help" command can be used for a quick reference.
|
||||
|
||||
3. Stop the userspace debugger interface
|
||||
|
||||
The interactive debugger interface can be closed by pressing Ctrl+C or using
|
||||
the "quit" or "exit" commands. When finished, unload the module with:
|
||||
|
||||
# rmmod acpi_dbg
|
||||
|
||||
The module unloading may fail if there is an acpidbg instance running.
|
||||
|
||||
4. Run the debugger in a script
|
||||
|
||||
It may be useful to run the AML debugger in a test script. "acpidbg" supports
|
||||
this in a special "batch" mode. For example, the following command outputs
|
||||
the entire ACPI namespace:
|
||||
|
||||
# acpidbg -b "namespace"
