iasl — ACPI Source Language compiler/decompiler

Synopsis

iasl [<option>...] <input-file> ...

Description

This manual page briefly documents the iasl command. The option list is taken from the iasl interactive help.

iasl is an ASL compiler and decompiler. This command provides both the ability to translate one or more ASL source files to their corresponding AML binary files, and the ability to translate AML binary files back to readable ASL source.

Much more detailed documentation may be found at http://www.acpica.org/documentation/.
