Introduction
In this tutorial we learn how to install acpica-tools on Ubuntu 20.04.
What is acpica-tools
acpica-tools is:
The ACPI Component Architecture (ACPICA) project provides an OS-independent
reference implementation of the Advanced Configuration and Power Interface
Specification (ACPI). ACPICA code contains those portions of ACPI meant to
be directly integrated into the host OS as a kernel-resident subsystem, and
a small set of tools to assist in developing and debugging ACPI tables.
This package contains only the user-space tools needed for ACPI table
development, not the kernel implementation of ACPI. The following commands
are installed:
– iasl: compiles ASL (ACPI Source Language) into AML (ACPI Machine
Language), suitable for inclusion as a DSDT in system firmware.
It also can disassemble AML, for debugging purposes.
– acpibin: performs basic operations on binary AML files (e.g.,
comparison, data extraction)
– acpidump: write out the current contents of ACPI tables
– acpiexec: simulate AML execution in order to debug method definitions
– acpihelp: display help messages describing ASL keywords and op-codes
– acpinames: display complete ACPI name space from input AML
– acpisrc: manipulate the ACPICA source tree and format source files
for specific environments
– acpixtract: extract binary ACPI tables from acpidump output (see
also the pmtools package)
