NAME
       iasl -- Intel ACPI compiler/decompiler

SYNOPSIS
       iasl  [-2cefghl]	 [-b  type] [-d	file] [-dc file] [-hc] [-hr] [-i type]
	    [-ln] [-ls]	[-oa] [-of] [-oi] [-on]	[-ot] [-p  prefix]  [-s	 type]
	    [-t	type] [-vi] [-vo] [-vr]	[-vs] [-x level] [-w level] input-file

DESCRIPTION
       The  iasl  utility  is  a  compiler/decompiler for ACPI Source Language
       (ASL) and ACPI Machine Language (AML).  Major features of iasl include:

	     	 Full support for the ACPI 3.0b	 Specification	including  ASL
		 grammar elements and operators.

	     	 Extensive  compiler syntax and	semantic error checking, espe-
		 cially	in the area of control methods.	 This reduces the num-
		 ber of	errors that are	not discovered until the AML  code  is
		 actually  interpreted	(i.e., the compile-time	error checking
		 reduces the number of run-time	errors).

	     	 Multiple types	of output files, including  formatted  listing
		 files with intermixed source, several types of	AML files, and
		 error messages.

OPTIONS
       -2      Emit ACPI 2.0 compatible	ASL code.

       -b p|t|b
	       Create	 compiler    debug/trace    file    (*.txt).	Types:
	       Parse/Tree/Both.

       -c      Parse only, no output generation.

       -d file
	       Disassemble AML to ASL source code file (*.dsl).

       -dc file
	       Disassemble AML and immediately compile it.  (Obtain DSDT  from
	       current system if no input file.)

       -e      Generate	External() statements for unresolved symbols.

       -f      Ignore errors, force creation of	AML output file(s).

       -g      Get ACPI	tables and write to files (*.dat).

       -h      Additional help and compiler debug options.

       -hc     Display operators allowed in constant expressions.

       -hr     Display ACPI reserved method names.

       -i a|c  Create assembler	or C include file (*.inc or *.h).

       -l      Create mixed listing file (ASL source and AML) (*.lst).

       -ln     Create namespace	file (*.nsp).

       -ls     Create combined source file (expanded includes) (*.src).

       -oa     Disable all optimizations (compatibility	mode).

       -of     Disable constant	folding.

       -oi     Disable integer optimization to Zero/One/Ones.

       -on     Disable named reference string optimization.

       -ot     Display compile times.

       -p prefix
	       Specify filename	prefix for all output files (including .aml).

       -s a|c  Create AML in assembler or C source file	(*.asm or *.c).

       -t a|c  Create AML in assembler or C hex	table (*.hex).

       -vi     Less verbose errors and warnings	for use	with IDEs.

       -vo     Enable optimization comments.

       -vr     Disable remarks.

       -vs     Disable signon.

       -x level
	       Set debug level for trace output.

       -w level
	       Set warning level.
