Hi!

I'm new to the list and I would like to request your help. I'm glad that some time ago I got setting the brightness working with the help of .. erm, I think it was Bruno Ducrot. I send him my DSDT or something. Since this time I learned a lot about that stuff and now need some help in debugging the DSDT of my Toshiba M30 Laptop. Trying to compile it with the intel compiler I get the following errors:

./iasl -tc dsdt.dsl

I already searched the internet to find common solutions for problems like this, but I couldn't find anything but a solution for the warning. Looking in the disassembly I found this concerning the errors:

Name (_PSL, Package (0x01)

            {
                \_PR.CPU0
            })

There were no other occurencies of PR.CPU0 than this and in the error lines.

Do you have any ideas? Is it worth correcting these errors? Can you tell if it will have any advantages? This is the context of one of the error lines:

Method (_PS0, 0, Serialized)
{
Store (0x00, \_SB.MEM.CRTS)
If (LEqual (\_SB.MEM.RPPC, 0x01))

     {
      Notify (\_PR.CPU0, 0x80)
      Store (0x00, \_SB.MEM.RPPC)
     }
}

And perhaps: can anybody tell me why it isn't possible to switch CRT or S-VIDEO on with the toshiba acpi driver? Is it possible to see this from the disassembly?

The file http://www.uni-koblenz.de/~tenshi/toshm30dsdt.tar.gz includes all the necessary files: dsdt.hex, dsdt.dsl, errors.txt

Thank you very much for any help!

Greetings,
Thomas Ch.

Hi!

Trying to compile it with the intel compiler I get the following errors:

Well, I don't remember if that's me.
But I have an acpidmp for a toshiba M30-404.

After doing something like this:

ducrot@neptune:~/acpi_hack/toshiba-M30-404$ ../pmtools/acpidmp/acpixtract SSDT > ssdt < acpidmp
ducrot@neptune:~/acpi_hack/toshiba-M30-404$ iasl-20041203 -d ssdt

and the resulting ssdt.dsl will contains the processor object.

So all you have to do is to add something like that:
External (\_PR.CPU0)
onto the dsdt.dsl in order to get rid of those errors.

A corresponding diff is:

dsdt.dsl +1 -0

I dont know for the toshiba acpi driver. But there is for sure support for the acpi_video driver in this dsdt.

It may be fine to test if by chance acpi_video work.

OK, thanks. I read something like this somewhere but was really unsure where to place the External Definition. So, is it worth correcting this and loading the new dsdt at boot? Will it help?

Ok, I wrote you already Bruno. I also posted a new Thread reagarding my experience with acpi_video.
