iasl – Intel ACPI compiler/decompiler



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


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


  Emit ACPI 2.0 compatible ASL code.
-b -Sm p | t | b Sm
  Create compiler debug/trace file ( *.txt). Types: Parse/Tree/Both.
  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.)
  Generate External() statements for unresolved symbols.
  Ignore errors, force creation of AML output file(s).
  Get ACPI tables and write to files ( *.dat).
  Additional help and compiler debug options.
  Display operators allowed in constant expressions.
  Display ACPI reserved method names.
-i -Sm a | c Sm
  Create assembler or C include file ( *.inc or *.h).
  Create mixed listing file (ASL source and AML) ( *.lst).
  Create namespace file ( *.nsp).
  Create combined source file (expanded includes) ( *.src).
  Disable all optimizations (compatibility mode).
  Disable constant folding.
  Disable integer optimization to Zero/One/Ones.
  Disable named reference string optimization.
  Display compile times.
-p prefix
  Specify filename prefix for all output files (including .aml).
-s -Sm a | c Sm
  Create AML in assembler or C source file ( *.asm or *.c).
-t a|c
  Create AML in assembler or C hex table ( *.hex).
  Less verbose errors and warnings for use with IDEs.
  Enable optimization comments.
  Disable remarks.
  Disable signon.
-x level
  Set debug level for trace output.
-w level
  Set warning level.
