Description Sebastian Smolorz 2008-02-08 04:16:06 UTC
Latest working kernel version: unknown
Earliest failing kernel version: 2.6.23.12
Distribution: Gentoo 2007.0
Hardware Environment: Panasonic Toughbook CF-52
Software Environment:
Problem Description:
The Linux kernel successfully boots only with acpi=off or acpi=ht. With the linux-acpi-2.6 git repository (test branch) from Febuary 2nd I managed to boot successfully twice with ACPI enabled. But this is not reproducable. Normally, the boot process stops early. dmesg output from successful and unsuccessful boot follows, as well as dmidecode output.

Successful boot with ACPI (linux-acpi-2.6 test branch Feb. 2nd):

acpidump output on Panasonic Toughbook CF-52
Comment 2 Len Brown 2008-02-09 02:27:04 UTC
Multiple issues in the dmesg above beg several questions...

> Latest working kernel version: unknown
> Earliest failing kernel version: 2.6.23.12

Has any version of Linux ever booted on this laptop in ACPI mode?
If so, what is the latest version you know of?

Are the dmesg above from unmodified 2.6.24,
or from 2.6.24-git (pre 2.6.25-rc1)?

Kernel command line: root=/dev/sda6 vga=0x318 acpi_osi=Linux
Kernel command line: root=/dev/sda6 console=ttyS0,115200

Does this laptop really have a serial console?
if you boot with these parameters several times,
does it succeed/fail the same way each time?
Did acpi_osi=Linux make a difference (all by itself)?

Any difference with CONFIG_PREEMPT=n?


Comment 3 Len Brown 2008-02-09 02:44:52 UTC
Reviewing the DSDT for use of OSI(Linux), I don't
see that Panasonic has any specific support for Linux.
Rather, OSI(Linux)'s main effect seems to be to run
the DSDT as if Windows NT were running.  In particular,
there is a bunch of USB code that gets disabled because
OSI(Linux) disables the Vista-validated path through the BIOS.

However, I don't fully follow the save/restore to INFO mechanism --
it could possibly have some implications on SMM code.

I'll be surprised if acpi_osi=Linux behaves differently
from acpi_osi=!Linux WRT. the boot problems reported here.
However, I wouldn't be surprised to see a differences
in suspend/resume function, or USB function.

The first kernel I tried on this laptop was version 2.6.23.12. I am not aware of any kernel version that booted in ACPI mode successfully and reliably. If you have any assumptions that a particular version could work please let me know so I can try it out.

The first dmesg is from the linux-acpi-2.6 repository, test branch, last commit from February 2nd. The second dmesg is from vanilla 2.6.24.

I don't log in via serial console but I use the serial output to save the dmesg.

Ok, I repeated the tests with a slightly more current linux-acpi-2.6 repository. It is the release branch, HEAD is commit a52500c917ead55dd78d9f37b8ca993f4f79f72a. I booted three times with acpi_osi=Linux and three times without it. It fails the same way each time. See attached boot logs (one with acpi_osi=Linux and one without).

> Any difference with CONFIG_PREEMPT=n?

No, not at all. (CONFIG_PREEMPT_NONE=y)

dmesg output is from an unsuccessful boot attempt. lspci output was taken when the system was booted with acpi=off.

Thanks for the info.
    It is very great that the system can be booted very normally. 
    The remained problem is that backlight can't work normally.
    Will you please do the following test based on the kerne in comment #20?( Custom DSDT table is required).
    a. boot the system with the option of "acpi.debug_layer=0x08010004 acpi.debug_level=0x1f pci=nommconf".
    b. press Fn keys for the backlight.
   
    After finishing the test, please attach the output of full dmesg.
    Will you please attach the output using the following command? 
    acpidump --addr 0x3f6cec47 --length 0x100 -o mnvs

Hi Yakui,

you were right, CONFIG_ACPI_VIDEO was disabled. I enabled it and attached the dmesg output of the new compiled kernel, again after pressing the 'lower backlight' button three times.

The following attachment is the used .config

Is there a chance that the Linux kernel ACPI code is modified in a way that no custom DSDT is necessary?

Thanks,
Sebastian

dmesg output with DSDT from comment #29 and after pressing the backlight button several times

Hi Yakui,

I've found the reason why at first I thought that the backlight buttons don't work. Actually, they work but only with 10 brightness levels whereas with acpi=off there are 21. The 9 lowest levels seem to be right but at level 9 pressing the increase button lets the display get the maximum brightness. However, /sys/class/backlight/acpi_video0/actual_brightness shows the correct values. They are between 0 and 100, pressing the backlight keys dec-/increases the value of 5. So the wrong behaviour starts at a value of 45 where the backlight is set to the maximum.

Linux failed to support the new Intel IGD Opregion BIOS.
Sebastian,
could you please verify if the backlight sys I/F can work in the latest kernel release, say 2.6.25-rc4? You don't need to use the hotkey, just poke /sys/class/backlight/acpi_video0/brightness and see if the backlight is actually changed.
Comment 33 Sebastian Smolorz 2008-03-07 07:52:20 UTC
Hi,

I tried 2.6.25-rc4 but the problem is the same. Only the numbers in /sys/class/backlight/acpi_video0/ changed e.g. max_brightness is now 20 while it was 100 in 2.6.23. Accordingly, the wrong maximum backlight starts with value 9 and not with 45 as it was before.

Yes, that's the right behaviour in 2.6.25-rc kernel. :p

What I really care about is that if the brightness of your laptop can actually be changed when you echo a valid value (between 0 and the "max_brightness") to the "brightness" file.

Yes, it can be changed this way but also in that wrong fashion I described earlier. There are only 10 actual brightness levels, between 10 and 20 there is no difference in the brightness.

IMO, the max_brightness is 9, and you can successfully change the brightness from level 0 to 9, write any value larger than 9 will return errors, right?

so what's the wrong fashion?
Please reminder me if I miss something. :)

If the notebook boots with acpi=off I can change the brightness in 21 levels (with the keys). I can actually see the brightness going up or down. So the notebook is really capable of changing the brightness in 21 levels. When it boots with ACPI enabled there are only 10 levels. The visual brightness difference between value 8 and 9 is noticeable larger than between smaller levels. Levels from 10 to 20 change nothing WRT the brightness - and no error is printed BTW.

So my conclusion is: The maximum brightness "comes to early". The upper 10 brightness levels are skipped.

So there are only 10 levels that actually works, while you can get 20 from reading /sys/class/backlight/acpi_video0/max_brightness, right?

Yes, ACPI does support 21 levels on this laptop.
Please attach the result of "cat /proc/acpi/video/GFX0/DD02/brightness".
and the content of /proc/acpi/video/GFX0/DD02/brightness after set it to some value lager than 10.

Regarding the settable brightness levels there is no difference. But there are other effects: During boot the brightness is set to the lowest level and the hot keys have no effect on the brightness any more.
Comment 47 Zhang Rui 2008-05-14 01:44:26 UTC
At the ACPI video driver's point of view, there is no difference to set the brightness level to 1 or to 15.
Both of them call into AML code and invoke
                    Method (EC0B, 1, Serialized)
                    {
                        EC83 (0x0B, Arg0)
                        Return (0x00)
                    }
I don;t know why it works when setting the brightness level to 0~9 and fails when setting it to 10~20.
I don;t know how to debug further and IMO we should close it and mark it as WILL_NOT_FIX.
What do you think, len?
