The ACPI Component Architecture project provides an OS-independent reference implementation of the Advanced Configuration and Power Interface Specification . 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 into AML , 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 -- 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 This version of the tools is being released under GPLv2 license.
