DSDT/ASL compiler error

DSDT/ASL compiler error

[Ben B]

Wondering if any ASL experts can help me here. I'm trying to recompile
the DSDT on my HP NC6400 laptop, to hopefully get some better acpi
functionality, and I'm seeing the following error:

Try:
CreateByteField (C1D3, \_SB.C002.C003.C334._X0F._LEN, C08F)
instead of
CreateByteField (C1D3, \_SB.C002.C003._X0F._LEN, C08F)
in line 12767. The rest should be harmless.

I'm not sure if that's one is harmless:
> > dsdt.dsl  3275:                                         And (Local1, 0xFFFF)
It's as if the asl writter wanted to clear the upper bits of Local1, but forgot to
assign it back to Local1.  It might be something like this:
	And(Local1, 0xFFFF, Local1)

It's only a rough guess though, and wihtout knowing what was the
original intention, and without the source of the ASL, it's hard
to tell for sure.

This is the context around there. I can send the whole asl if you'd like
also:

                                Store (C15B, Local1)
                                If (Local1)
                                {
                                    If (And (C165, 0x40))
                                    {
                                        Add (Not (Local1), 0x01, Local1)
                                        And (Local1, 0xFFFF)
                                    }
                                }

                                Store (Local1, Index (DerefOf (Index (Local0, 0x02)), 0x0E))

Of particular interest that I'd like to get going also is the built in
accelerometer, which I only discovered browsing the ASL:

            Device (ACEL)
            {
                Name (_HID, EisaId ("HPQ0004"))

"HP Mobile Data Protection Sensor"....but that's for another project. :)

Thanks.

I checked on a very similar DSDT table:
This line seems only to be used for the WMAA method:
Method (WMAA, 3, NotSerialized)
{
    Return (C23E (Arg1, Arg2))
}
C23E->C24B->C1AB(in this function is the line), the functions are only
used once in DSDT.
I expect this method is part of the Windows Management Instrumentation
(WMI -> [1]).
The functions might have other names in your dsl output file.
As the WMAA function shouldn't get used on a current linux system it
should be harmless in the end.

(unfortunately, I hoped that was the missing hint to fix some things on
this system).

Sorry Ben, I can't help you with the HPQ0004 device, I don't know
anything about this one and don't have such a machine myself.

Thanks again,

     Thomas

Sound like it really should be And(Local1, 0xFFFF, Local1).

What things need to be fixed?  I'm just curious.

- _PPC always returns 1, therefore highest freq cannot be set
  (also reported recently on cpufreq list)
  https://bugzilla.novell.com/show_bug.cgi?id=179702

- The other one could be an EC issue:
  battery and AC status is not updated.
  May be an interference with the mouse driver from the comments,
  no idea yet.
  https://bugzilla.novell.com/show_bug.cgi?id=200169

Any hints are greatly appreciated...
AFAIK both (at least first on several Core Duo models) phenomenons seem
to happen on several (all?) new HP models.

My first though is to try atpic instead of apic and maybe tweak
apci_sci= parameter?  I'll look more in details the bug.

Also I'm wondering why there is a \_PR.CPU0.INI() method.  I'm wondering
if it should be a _INI instead.  But it seems it's a workaround for some
others OSs and I'm not sure if we have to call the SMM implied by that
_INI in order to fix that since Linux should have done something similar
already?

Strange.
