Problems installing ACPI

Problems installing ACPI

[Christian Brix Folsted Andersen]

I'm running RedHat 8.0 on my Compaq EVO N160 laptop.

To install ACPI i downloaded the linux-2.4.20 kernel from www.kernel.org
and patched it with acpi-20021212-2.4.20.diff.gz.

I had some promblems compilling the kernel but when I left out scsi
support the problem disappeard. However when I boot the new kernel it
hangs with this message:

ACPI: Interpreter enabled

As far is I know, it's because of some errors in the DSDT of the Compaq 
Evo N160. I also have this notebook and have fixed at least the obvious 
errors (and wrong information about the battery).

--> You should take a fixed DSDT and include in into your kernel.

Steps:
- Get a fixed DSDT. You could try mine from 
http://www.ettelbrueck.de/linux-acpi/compaq-evo-n160/acpi_dsdt.asl , but 
you should alter it to fit to your battery. I've coded the current 
maximum capacity of my battery (3357 mAh instead of 4000 mAh for a new 
battery) into it - see my posting of 14 december 2002 for details about 
the battery part.
- Compile your DSDT with Intel's ASL compiler into a c source code file 
and copy it to kernel-src-dir/drivers/acpi/tables/acpi_dsdt.c.
- [Don't know by heart if this is needed with current acpi patches] 
Apply a patch to your kernel that makes it use your DSDT.
- Compile your kernel once again.
- Boot it...

I'm sorry that I couldn't write it in more detail, but I my Evo N160 is 
not running at the moment and I'm busy... I hope you'll find out how to 
use the information I could give you by now.

Some links that could help you, especially for finding Intel's ASL 
compiler and patching your kernel:

I've updated the DSDT files on my web server concerning the maximum and 
last known capacity of the battery: Both are now set to the default 
value of 4000 mAh, so there's no longer a need for you to change anything.

You can now skip this part and directly use
http://www.ettelbrueck.de/linux-acpi/compaq-evo-n160/acpi_dsdt.c

> - [Don't know by heart if this is needed with current acpi patches]

I found the patch I used to make my kernel use my fixed DSDT. You can 
download it from
http://www.ettelbrueck.de/linux-acpi/compaq-evo-n160/acpi_use_own_dsdt-2.4.20.diff

> - Compile your kernel once again.

These two steps are obviously still needed ;-)

Re: Problems installing ACPI

[Christian Brix Folsted Andersen]

Hi Heiko

Thank you so much for your help.

However i am having a bit of a problem applying your patch. The file
drivers/acpi/osl.c does not exist instead there is a file called os.c.
I looked at the file and tried to patch it manualy, but can not find the
position of the last part of the patch.

The first part was added at line 85 of os.c

static int acpi_irq_irq = 0;
static OSD_HANDLER acpi_irq_handler = NULL;
static void *acpi_irq_context = NULL;

extern unsigned char AmlCode[];

In which function is the last part supposed to go?
Which kernel did you use?

regards Christian

I use a vanilla kernel 2.4.20 with the ACPI patch 20021205. Did you use 
another ACPI patch? Perhaps this part has changed...

The last part of the patch is for the function acpi_os_table_override:

<<original>>

acpi_status
acpi_os_table_override (acpi_table_header *existing_table, 
acpi_table_header **new_table)
{
         if (!existing_table || !new_table)
                 return AE_BAD_PARAMETER;

         *new_table = NULL;
         return AE_OK;
}

<<patched>>

acpi_status
acpi_os_table_override (acpi_table_header *existing_table, 
acpi_table_header **new_table)
{
         if (!existing_table || !new_table)
                 return AE_BAD_PARAMETER;

         *new_table = NULL;
         if (strncmp(existing_table->signature, "DSDT", 4) == 0)
                 *new_table = (acpi_table_header*)AmlCode;
         else
                 *new_table = NULL;
         return AE_OK;
}

I hope this will help. Please tell me whether you had success ;-)

Heiko

Re: Problems installing ACPI

[Christian Brix Folsted Andersen]

Hi Heiko

So far so good. This is what i have done:

I used the kernel linux-2.4.20 from kernel.org

Downloaded this patch from sourceforge: acpi-20021205-2.4.20.diff.gz

Applied the patch and afterwards your
patch:acpi_use_own_dsdt-2.4.20.diff (no errors ths time)

Copied acpi_dsdt.c to drivers/acpi/tables/

Compilled the kernel without any problems.

But when i boot the kernel it hangs with the same error as previous.
However i read at this site: http://repose.cx/n160/ that passing the
parameter "pci=noacpi" should solve the problem. It did. Well at least
the booting problem.

I do not know if the acpi is working correctly. When i enter the power
control setup in kde i get this message:

Your computer seems to have a partial ACPI installation
probably ACPI was enabled, but some of the sub-option
were not enabled - you need to enable at least 'AC Adaptor'
and 'Control Method Battery' and rebuild your kernel

I did enable both of these. What can i do next?

regards Christian

I forgot to mention that - sorry! I also use that boot option, my 
notebook won't work without it, too.

I haven't used ACPI tools in KDE yet, as I prefer Gnome at the moment 
(there's a Gnome tool called battstat_applet that shows the current 
battery state, it works fine for me). That's why I have to guess where 
the issue could _possibly_ be...

When your Evo has booted, please have a look into the /proc directory. 
Do you have a directory called "acpi" there? What is inside? There 
should be e.g. a directory "battery" which contains another directory 
for each battery (should be "CMB0" for the Evo N160). In 
/proc/acpi/battery/CMB0, you should find some pseudo files which provide 
information about your batter, e.g. "info" for general information and 
"state" for the current state of the battery. If you have these 
directories and files, please tell me about the content of "info" and 
"state".

Heiko

Both look good, as they should.

I've tried KDE 3.0.4 (part of SuSE Pro 8.1) on my Evo N160 and got the 
same weird message complaining about missing ACPI support. Unfortunately 
I don't know what you should try next. I could imagine the KDE power 
management tool uses another (fixed) directory name for the battery, the 
AC adapter etc. or something like that. There were similar problems 
discussed on this list in the past, but I didn't read them because I 
didn't use KDE.

I recommend you post another question about this problem on this list. 
This way I'm convinced you won't have to wait a long time until you get 
the information you need. You could also have a look at the list archive 
and try to find out if this issue has already been discussed here.

I'm sure you'll manage it ;-)

Heiko

Alternatives are to patch klaptopdaemon for the right paths or
upgrade to KDE3.1 where it has been fixed.

You may prefer to put up with it until KDE3.1 has been officially
released (expected soon).

There is a patch on my website which I have used previously, although it
is not well written.  I found it by digging around the web.

You use the vanilla kernel.  Not a kernel with the latest
ACPI patch.  For the vanilla one, you have to use the
workaround found at 
http://developer.intel.com/technology/iapc/acpi/bios_override.htm

but you actually should first consider to patch your
kernel found at http://www.sf.net/projects/acpi/
