My ACPI stopped working when I added an additional 256mb RAM to my vpr
Matricx 174b4 laptop. It has 256mb already, I added 256mb to make it
512mb and I got a bunch of AE_NO_MEMORY errors in the ACPI code.
I took the extra RAM out, and the ACPI support works.
I am using kernel 2.6.1 with acpi patches. I had the same problem on
2.6.0. On 2.4.20 with acpi patches the machine would not even boot with
the extra memory.
I have a custom DSDT file that I fixed errors in. When it was working on
2.4.20 It looked like all the ACPI features were active and functional.
Any ideas on what to look for?
Here is a sample of the boot log:

Maybe the root of this error is that __ioremap don't allow anybody to
remap
normal RAM. Could you verify it by checking it in arch/i386/mm/ioremap.c

Recompile your DSDT. Since the amount of RAM changed and you're probably
using old DSDT containing wrong addresses, no wonder you're hitting errors.

Is this correct? If a user adds or removes memory, then the
DSDT must be rebuilt? Sheesh!! That's bad if this is correct.

Many BIOSes patch the DSDT according to the system configuration (e.g.
rename \_S3 to something other if Suspend to RAM is disabled in the
setup). Probably some BIOSes put the memory size into DSDT this
way...

Most DSDT are actually build on POST stage.

Patch the DSDT on runtime. Or add a checksum on the original DSDT.

Yes, that's a necessity in most cases. Why do you consider it that bad?

That seems quite backwards to me.
Why should we consider that a good thing?
I discussed this with Andy Grover and he said that the DSDT isn't
where the memory size is defined. It should just be coming from
the e820 BIOS calls, not from ACPI DSDT etc., which certainly
made sense to me, as that is something that a user wouldn't need
to modify after changing the memory size of a system.

Sure! I got it 99% working, but I am getting an AML_UNINITIALIZED_LOCAL
error message, which is pretty annoying because I can't see why its
throwing that error.
Trying with an unmodified DSDT doesn't really show much because it has
several bugs that cause the ACPI features to not work at all. I can
capture the two different streams of error messages.

Dave,
Can you capture the e820 messages from the beginning of dmesg for the
success and failure case so we what the BIOS says about your RAM? Also,
it would be good to try w/o the custom DSDT.
Thanks,
-Len
Ps. Contrary to popular perception, e820 is defined in the ACPI spec.

I think you're getting me wrong here: the DSDT clearly does not define the
amount of RAM used by the system, but being dynamically generated by BIOS,
it may include references to fixed memory addresses that can vary with the
amount of RAM installed.
If those addresses change due to such an upgrade, overriding the
BIOS-generated DSDT (containing the right addresses) with one that was
obtained from a system with a different amount of RAM (with addresses
correct for that amount) may indeed not work.

The user shouldn't need to supply his own DSDT in the first place.

IMHO that a bad thing.

I'm not sure if the tables are copied upon e820 calls, but I think
there are copied on POST at least on Phoenix BIOS (that what I
understood from their documentations). Also most of time, the
AML need somehow to access to the nvram, which is located typically
relative to TOM. Also, when you add/remove memory modules, there
there is chance that mmio regions are not the same, and
aml need to know that.

To clarify this further, most AML I've seen uses various named regions to
store information about the platform that is dynamic. For instance, the
actual clock rates and power consumption of the various ACPI performance
states on my Thinkpad are set up at boot time by an _INI method under the
Processor object. That way if I plugged in a different CPU, it would be
detected at boot time, not hard coded in the AML. For the case of memory
size and this laptop, that should really be done through the E820 table by
the BIOS and not hardcoded in the AML.

I'm interested in the AML code that cause AML_UNINITIALIZED_LOCAL,
Can you show me. Maybe we can come up with some generic solution.

Did you check memory at 000000000FF7FDBD, size 190 has
been reservered.
