the first function.

im still not able to solve these:

Steve,

If I understand correctly, for the first error "Not all control paths return a value" in the code, you included the return lines shown below (the ones without numbers) and the warning still appears. If this is the case, I am very sorry I do not know what else you should do.

Code: Select all

hi mimosinnet!

Yup thats right, I think theres a different fix needed there.
But thanks for your help!

Best,

any idea about those errors? I can't find clues

[kreon28]

In a Wiki chapter I found out that I can use windows dsdt.dsl :

Hopefully you ended up with a fully readable dsdt.dsl file that you could move into your Gentoo install.

That's great but where should I move that file, just to let Gentoo use it instead of my old broken file?

Hi everybody,

I've got an HP Compaq 6715 b (ATI SB 600 chip, ATI Express 1200, Sempron 3300+) and installing linux on this is making me totally crazy!

I tried many distribs, and it's all the time the same problem...

When I boot without any parameter, the screen goes black and the system hang while booting.
With acpi=off, the system boots quickly (about 1 min 30) and everyhting is working great, without power management (fans don't stop turning loudly).
With noapic or noapic nolapic the system work great, the power management is great, but the system is veeeeryyyy slooooow (about 4 minutes to start up). The Gnome applet showing cpu frequency seems to work correctly too (from 800 mhz = 40 % to 2 ghz = 100%).

I've got a buggy DSDT:

Anyone know what to do to fix sillyness like:

Code: Select all

ouka.dsl   332:             Store (Local0, Local0)
Error    4049 -                         ^ Method local variable is not initialized (Local0)

This of course makes absolutely no sense... Has anyone figured out a way to figure out what this statement was initially trying to accomplish? Or what to do to fix something like this?

(This showed up on my Abit IS7 and Foxconn G9657MA motherboards, eerily similar errors. Both use Award BIOS I think.)

My Foxconn's WOL doesn't work (there seems to be another warning related to that) as well as hangs randomly on boot while detecting ACPI... wonderring if this is related...

It looks as if they were trying to push a value on the stack, doesn't it?. It should be safe to comment it out, as local variables are destroyed on exit and I typically find these at the end of methods. (According to the spec from Intel which, I might add, is 631 pages of incomprehensible @!#$%!! It's either poorly written or really well obfuscated.) My mobo uses an Award BIOS as well so I'll assume that's the common link. It may be possible to follow the methods backwards and see if they are expecting a return (as opposed to twiddling a local variable the way you would a global.)

Anybody here who can help me with this?

[jetblack]

I'm a little out of practice, but it looks like your 11 errors are still related to that ^CPU0._PPC call. I think I'd try replacing the remaining ^CPU0._PPC references with CPU0._PPC, especially since you've redefined the function call). That's probably why it's saying it can't find the function now. I'd see if that gets you down to the one warning about the WMBB call. I think you're ok at that point. All the warning is saying is that not all of the branches in the WMBB function return values. If the function doesn't hit those branches, it should be fine.

[jetblack]

Also, if you want to get rid of the warning, I'd throw in some "Return (Zero)" statements in this block of the WMBB function:

Code: Select all

If (LEqual (Arg1, 0x02)) {}
                If (LEqual (Arg1, 0x03)) {}
                If (LEqual (Arg1, 0x04)) {}
                If (LEqual (Arg1, 0x05)) {}
                If (LEqual (Arg1, 0x06)) {}
                If (LEqual (Arg1, 0x07)) {}
                If (LEqual (Arg1, 0x08)) {}
                If (LEqual (Arg1, 0x09)) {}

That should at least clear up the warning. To be fair, though, I haven't really looked at what that function is supposed to be doing. I'm assuming, though, that if they didn't bother putting return values in those branches at all, then they can't be too big of a deal.

I tried some things, but changing ^CPU0 to CPU0 was probably not a good idea. I guess i just created a new error, which inhibited the detection of the old errors.
The first error is

Code: Select all

ACPI Error (nsaccess-0531): ACPI path has too many parent prefixes (^) - reached beyond root node [20080701]                                                    

and is followed by this one

and a lot of these

Code: Select all

dsdt.dsl    26:     Mutex (MUTX, 0x00)
Error    4062 -               ^ Object does not exist (MUTX)

Unfortunately i have absolutely no idea, what to do. I wrote to the clevo support, but they did not even answer. I just can't believe, that nearly every board has buggy dsdt tables....
Thanks for your help!

I have a Clevo M570RU Laptop as well.

Here is mine if anyone has any ideas? I have over 200 of them. Just about all of them are error 4062 but I can't seem to find anything on that.

because the files are quite long I'll upload them to the net. I don't see an attachment button for the forum. I hope I'm not going blind...

OK I changed all ^CPU0._PPC calls to CPU0.PPC and now only get 12 errors. the new list is below.
It looks like kernelhacker is having the same issue I am. Although I'm not suprised. He has the same laptop it looks like lol. Damn Clevo and their buggy DSDT lol.

weeeeee!!!!!

I replaced all ^CPU0._PPC with \_PR_.CPU0._PPC
and then added a Return function for the WMBB warning.

here is my fixed dsdt (untested) --> http://www.sendspace.com/file/srkcob

laptop Sager NP5790 (a.k.a. CLEVO M570RU)
here is the bios image I am using as well. ver- 1.00.12aSL ; current as of 15JAN2009 --> http://www.sendspace.com/file/5xc9k9

I have not yet tried it but will edit this post when I do.

[riczan]

Help, I also have a sager 5793, same bugs and same fix.

However, when I replace the dsdt in the kernel (I'm using the hex file method), after booting up I get the same errors.

Also if I check the current /proc/acpi/dsdt file I see that it is not patched!!! what is going on?

dmesg reports that I'm using the new dsdt:

Code: Select all

ACPI: Override [DSDT-CRESTLNE], this is unsafe: tainting kernel
ACPI: Table DSDT replaced by host OS

Also dmesg says that,

Code: Select all

DSDT override uses original SSDTs unless acpi_no_auto_ssdt

I've tried with and without this flag and I get the same result.

this is very strange. What did I do wrong.

For the hex method there are 3 flags that must be set. All the guides said that
CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="/usr/src/dsdts/mydsdt.hex"
CONFIG_STANDALONE=n

The last option in gentoo looks like this:
# CONFIG_STANDALONE is not set

is this the same as =n, could this be the problem. However, I don't get compilation errors and the dsdt seems to be loaded but is not working...

Please help, I feel we are so close now.

[kodiakmax]

Well, I'm having problems compiling mine into the kernel. So I'm going to try the initramfs method. Probably better that way anyway, so I can test different changes to the dsdt more easily.

[riczan]

did you have the flags set as I described above?

First you need to unset the STANDALONE option. You find it in device drivers/general setup/

only then you will see the other option in the acpi menu.

I'm using 2.6.28-tuxonice-r1 sources. Let me know if the initrd method works. I haven't tried it because I think the kernel needs to be patched, so I would need a vanilla kernel (I think).

Good luck,

anyone else? suggestions are wellcomed...

[kodiakmax]

Yes I did try the following kernel options

CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="/home/kodiakmax/iasl/work/dsdt.hex"
CONFIG_STANDALONE=n

However, When I reboot I do not get a dmesg output notifying me that custom dsdt is in use.

I have now just tried the initramfs support with the following patch --> http://gaugusch.at/kernel.shtml

I then enabled the following kernel option

CONFIG_ACPI_CUSTOM_DSDT_INITRD=y

I then used this script --> http://gaugusch.at/acpi-dsdt-initrd-pat ... d-add-dsdt
to append the dsdt to the initramfs, when I reboot again there is still no dmesg notifying me of a custom dsdt in use.

I haven't tried it because I think the kernel needs to be patched, so I would need a vanilla kernel (I think).

You shouldn't need vanilla kernel sources for this patch. Just follow steps 9b on page1 of this thread if interested. Use the patch for kernel 2.6.28 with the link I provided above.
Although with neither method working for me, take my advice with a grain of salt! lol

[riczan]

Are you sure your dmesg before and after are identical? Did you compare line by line? I find it hard to believe that there are absolutely no changes... you should at least get somehting saying that you are using a custom dsdt... or failed to use custom dsd or something.

did you recompiled the kernel?

did you updated your grub?

I also want to report that I tried the acpi_os_name="Windows 2001 SP2" with no apparent effect. (I read the dsdt.dsl to get the "Windows 2001 SP2").

Finally, I contacted Sager customer service just for the sake of it, requesting a BIOS upgrade . They told me to disable the robson option in the bios... I don't see how that is related but you may want to try that. (I think this is the automatic response to the word "Linux")

I have it on because that enables the AHCI support for hardrives but I will disable it and see what happens on a gentoo bootup CD. I don't know if that will brake my current linux installation (that's why I want to try the CD first)

You can try that too.

Don't give up. Since this is not a threat, just a discussion, perhaps we would get more help on a different forum.

I'll see were I go with the initrd but your tests don't seem very encouraging.

good luck

[kodiakmax]

I have had the robson disabled for quite some time now. So, that's not it for me. The BIOS image in my post above is the most current straight from sager tech support. Clevo's most current BIOS image is actually 1.00.11 So, sager has done something to it. However, I am unable to find out what.

I too find it very strange that I can't get the custom dsdt loaded with either the kernel or initramfs method.

here is a quick output after kernel reconfig and reboot. This time I tried both .hex method and initramfs method together.

My grub does not really require updating as my /boot is not on a seperate partition. However, I did edit the grub.conf to use the modded initramfs. The modded initramfs does include the DSDT.aml in it's file list as well verified through the following command

I see the light at the end of the tunnel...

I rebooted with the gentoo CD and dmesg reports no errors!!! The /proc/acpi/ac_adapter directory is not empty anymore!!!

This is good news... but I'm not sure how to interpret this yet. Is my current kernel buggy? or is it a option in the .config that I'm missing?

I'll try both aproaches and I'll report back. It will take me some time to go through all the config file... can some one suggest what could be the possible relevant sections that should be identical? (other than the obvious ACPI section).

But this is good, if I don't get it we can always use the genkernel and have full ACPI functionality... of course, if I wanted a genkernel I would be using ubuntu instead.

cheers

Unfortunately I don't see the kernel version in the dmesg of the gentoo boot CD. But I see some obvious differences already,
gentoo CD:

Code: Select all

ACPI: DMI System Vendor: SAGER
ACPI: DMI Product Name: M570RU
ACPI: DMI Product Version: CLEVO:M570RU-1.00.12S
ACPI: DMI Board Name: SANTA ROSA
ACPI: DMI BIOS Vendor: Phoenix
ACPI: DMI BIOS Date: 01/14/2009

my current 2.6.28-tuxonice-r1

Code: Select all

DMI present

That's it

This looks more like a flag I'm missing.

I also checked the dsdt.dsl file used by the gentoo CD and the "bad" code is there External (^CPU0._PPC) and yet, the gentooCD kernel has no problem with that... this makes me very suspicious of the whole compiling of the dsdt.dsl to check for errors.

enough for now.
