Compiling Intel's ASL Compiler iasl

ACPI is the Advanced Configuration and Power management Interface. ASL is the language used to compile the tables describing the computer's hardware. In some cases it may be helpful to edit some of those tables, most notably the DSDT.

There are several methods to dump the ACPI tables. Given the dump of an ACPI table, one typically wants to decompile the ".aml" file, modify the resulting ASL code (often with the ending ".dsl") and finally recompile it. These two feats are accomplished by Intel's ASL compiler "iasl". You may just want to download the binary at the end of the post and put it in /usr/local/bin or you can compile it yourself as outlined below.

Update: As reported by Slice, the latest version ("acpica-unix-20110623") compiles with a simple "make", at least on Lion 10.7.1 with Xcode 4.1.

1. You need xCode installed (from the App Store, free download for Lion)
2. Get the current source from http://www.acpica.org/downloads/unix_source_code.php
3. Open Terminal, change dir to where you want to have your source code.
4. Extract the source tarball by running

CODE

tar xf ~/Downloads/acpica-unix-20110623.tar

5. Change directory to "compiler"

CODE

cd compiler

6. Run the following command:

CODE

make

8. You get a file called "iasl" the current directory... this is your ASL compiler

. To install you can just issue:

CODE

sudo cp iasl /usr/bin/

(there is no need to set the permissions, the linker does that for you)

CODE

It was more of a rhetorical question since this post in no way explains what iasl compiler does.

Thanks pater. For next time, please note that stating the above instead of asking a rhetorical question may lead to a more prompt response from my side.

Thank you for the trick. Before I can't make iasl. Now Yes!

New iasl works without problems.

Thanks for the feedback, Slice. I also was not able to compile iasl until Kabyl told me how to do it, so all credit goes to him.

I also made acpiexec -ACPI Execution and Debugging.

QUOTE

sergey:acpiexec sergey$ /acpiexec

Intel ACPI Component Architecture
AML Execution/Debug Utility version 20090521 [Aug 26 2009]

Usage: acpiexec [Options] [InputFile]

Where:
-? Display this message
-a Do not abort methods on error
-b <CommandLine> Batch mode command execution
-e [Method] Batch mode method execution
-i Do not run STA/INI methods during init
-m Display final memory use statistics
-o <OutputFile> Send output to this file
-r Disable OpRegion address simulation
-s Enable Interpreter Slack Mode
-t Enable Interpreter Serialized Mode
-v Verbose init output
-x <DebugLevel> Specify debug output level
-z Enable debug semaphore timeout

Same trick
1. cd project/tools/acpiexec
2. Edit makefile
replace

CODE

acpiexec : $(patsubst %.c,%.o, $(SRCS))
$(CC) $(LDFLAGS) $(patsubst %.c,%.o, $(SRCS)) -lpthread -lrt -o $(PROG)

CODE

LDLIBS = -lpthread -lrt

acpiexec : $(patsubst %.c,%.o, $(SRCS))
$(CC) $(LDFLAGS) $(patsubst %.c,%.o, $(SRCS)) $(LDLIBS) -o $(PROG)

3. Edit osunixxf.c - this is a file from 2008 project but I need to correct according 2009
Line 144

CODE

/* Upcalls to AcpiExec */
//Slice
void
AeTableOverride (
ACPI_TABLE_HEADER *ExistingTable,
ACPI_TABLE_HEADER **NewTable);

Line ~260

CODE

#ifdef ACPI_EXEC_APP

    /* This code exercises the table override mechanism in the core */

    if (ACPI_COMPARE_NAME (ExistingTable->Signature, ACPI_SIG_DSDT))
    {
        /* override DSDT with itself */
//Slice
        // *NewTable = AcpiGbl_DbTablePtr;

        AeTableOverride (ExistingTable, NewTable);
//
    }
    return (AE_OK);
#else
    return AE_NO_ACPI_TABLES;
#endif

4. make LDLIBS=' '
Enjoy!

One useful trick
In DSDT you can encounter infinite loop waiting for hardware bits

QUOTE

**** Exception AE_AML_INFINITE_LOOP during execution of method [\SMI_] (Node 0x101ca8)

So it is better to make debug version of dsdt.aml
This is my SMI

CODE

    Method (SMI, 2, NotSerialized)
    {
        Acquire (SMIX, 0xFFFF)
        While (Zero) {}
        Store (Arg1, \_SB.SMIA)
        Store (Arg0, \_SB.SMIC)
        Store (\_SB.SMIC, Local0)
        While (Zero) //LNotEqual (Local0, Zero)) -- for Debug only I replaced condition to Zero
        {
            Store (\_SB.SMIC, Local0)  //-- waiting for hardware
        }

        Store (\_SB.SMIA, Local1)
        Release (SMIX)
        Return (Local1)
    }

The same in method SXX6().
Find your own problem!

Another problem

QUOTE

Executed 3 _INI methods requiring 0 _STA executions (examined 97 objects)

So you can start with option -i ( Do not run STA/INI methods during init)
acpiexec -i dsdt.debug.aml

I downloaded the two source archives and tried to compile iasl. osunix.c is not present in any of them.

There's a file named osunixxf.c but using that instead doesn't work:

Did you use new sources 2009 with replaced file osunixxf.c from project 2008? Look also my correction in step 3.

Think they are talking about step 7 in zhell's first post for iasl.
That needs to be osunixxf.c instead of osunix.c

And yes, replacing osunixxf.c from 2008 to 2009 sources still works.

Here's iasl Sept-03-2009.

To make it even easier, follow this:

Grab the sources from http://www.acpica.org/downloads/unix_source_code.php, open a Terminal window and after having extracted the tarball;

CODE

       cd compiler
       export CFLAGS='-DACPI_USE_ALTERNATE_TIMEOUT -include pthread.h'
       make LDLIBS=

You get the iasl tool in the current dir. To install you can just do:

CODE

sudo cp iasl /usr/bin/

(there is no need to set the permissions, the linker does that for you)

Thanks to np_ for the #include <pthread.h>

Apparently the resulted tool doesn't work, anyone had any success with that? or to be more precise, anyone "spent time" with this and has a fix?

EDIT:
Attached is a patch against acpica-unix-20091013, until someone cares enough to provide something better.

Thanks! It works.
Some new feature

CODE

Global:
-@<file> Specify command file
-I<dir> Specify additional include directory

Compile/decompile seems to be same.

Also new debugger
