x230: unhandled HKEY event 0x6050

x230: unhandled HKEY event 0x6050

[Borislav Petkov]

Hi all,

I get this in dmesg with 3.9-rc1:

[   12.951434] thinkpad_acpi: unhandled HKEY event 0x6050
[   12.951438] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net
[   13.516752] thinkpad_acpi: unknown possible thermal alarm or keyboard event received

when pressing Fn+F8/F9, i.e. the display backlight keys. I'm loading
thinkpad_acpi with brightness_enable=1 and booting the kernel with
"acpi_backlight=vendor" so that the backlight intensity gets controlled
by thinkpad_acpi. But the last maybe shouldn't complain about it, no?

Thanks.

It shouldn't even work right on a x230, that box should be doing standard
ACPI backlight control...

The standard ACPI crap doesn't work - if I don't boot with
acpi_backlight=vendor I get a blinding max level backlight which cannot
be modified by pressing the keys.

The thing is, with "acpi_backlight=vendor" and thinkpad_acpi loaded
with "brightness_enable=1" the backlight actually gets modified nicely
so thinkpad_acpi supports it after all. Maybe the simplest fix is for
thinkpad_acpi to shut up about this button when brightness_enable is set
and maybe when the model is x230?

Hmm.

Great, another fit-the-hardware-to-the-software idiocy because those
dimwits which call their pile of stinking software running in ring 0 the
parts of a house want to control every-f*cking-thing. Sigh :(.

Thanks for the links Yves-Alexis, certainly a sad read.

Hmm, I don't follow.  thinkpad-acpi does run on ring 0, so was that aimed at
me?  Or are you complaining about the Win-8 bug-to-bug compatibility madness
Lenovo added to the ACPI firmware?

Huh, is "thinkpad-acpi" the name of a part of a house? :-)

Of course, I was simply ranting at the fact that hw vendors like lenovo
need to do all kinds of dancing in the BIOS just so they can get their
windoze certification. I know, I know, they don't have a choice and we
have more of those windoze workarounds in the kernel but we shouldn't.

Btw, what your signature says is very fitting to the occasion. :)
