acpica

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 -- 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) This version of the tools is being released under GPLv2 license.
