rf kill button not working on hp folio 9470m - bisected

[Fabio Coatti]

Hi all,
on my laptop (hp folio 9470m), the rfkill button works fine on 3.6.10
and 11 (don't know about older kernels), but is not working on 3.7.X
(latest tested is 3.7.2).
On non working kernel, log shows the following messages:

Jan 13 17:34:33 calvin kernel: atkbd serio0: Unknown key pressed
(translated set 2, code 0xf8 on isa0060/serio0).

On working kernels, same logs shows the following lines:

I've tried to bisect the regression, and I've got this:

I've reverted this commit in 3.7.2 and now the rfkill button is
working just fine, so it seems the real culprit (well, I have no
knowledge about acpi so I say so only because reverting it fixes the
issue)
Please forgive me If I'm completely wrong  :)

Does rfkill button means Fn+F12 key on your machine?

Looks your machine emit e078 code when it switch to Windows 8 code path.
Please tail your log and press Fn key for make sure it emit e078 code.

I didn't see e078 code in hewlett-packard keymap file in udev, currently
it define 0xD7 to be the wlan key.

hmm... this machine changed wlan0 status on working kernel and also emit
e078 code like on Windows 8 mode.

Then I think your machine control RF power by different way but BIOS,
maybe wmi or other ways.

Please attached on your DSDT, hope OEM do those things through ACPI.

Please try acpi_osi="!Windows 2012", it will switch back to Windows 2009
mode. Then look at does things better than before?


Thanks a lot!

No, it is a "out of layout" key (this laptop has two of them, rfkill and mute) 
under Fn+Fx there is several other functions, some working and some not, but 
this is another story :)

Confirmed:

Jan 14 08:51:55 calvin kernel: atkbd serio0: Unknown key pressed (translated 
set 2, code 0xf8 on isa0060/serio0).
Jan 14 08:51:55 calvin kernel: atkbd serio0: Use 'setkeycodes e078 <keycode>' 
to make it known.

Done; I've tried to recompile it with iasl and I've got hundreds of errors, 
not a good sign I fear. I'll try to upgrade the firmware, even last time I 
tried the operation failed.

Ok, just tried; I can confirm that with acpi_osi="!Windows 2012" the rfkill 
works again, as it worked before the commit reported. 
Incidentally, it also fixes the issue with lcd backlight that I reported 
before.
