hp-wmi: info hotkey has no keycode or scancode

hp-wmi: info hotkey has no keycode or scancode

[Dennis Nezic]

Guys, the "info" illuminated touch-key (hotkey?) on my laptop "doesn't
work", showkey doesn't report any keycode or scancode. I don't see any
wmi related error messages from dmesg. All the other illuminated
"hotkeys" work fine, although confusingly evtest and "libinput
debug-events" report that they're coming through the event interface
associated with "AT Translated Set 2 keyboard" instead of "HP WMI
hotkeys", but hey, as long as I receive them I'm okay :p.

hp-wmi.c does seem to reference it:
  { KE_KEY, 0x213b,  { KEY_INFO } },

How can I go about troubleshooting this? (I'm using kernel 6.6.8)

Hello,

it can be possible that you machine does not use hp-wmi to deliver keycodes
to the operating system, but instead emulates a standard keyboard controller.

Can you check with "kacpimon" that events concerning a PNP0C14 device are being
received?

Thanks,
Armin Wolf

Very possible indeed. "kacpimon" doesn't show anything when I press that
touchkey, but it does when I press all the other touchkeys. (I do get
lots of accelerometer noise.)

Interesting, can you please share the output of:
- "kacpimon" while you where pressing the buttons
- "acpidump"

Actually I was finally able to detect something via kacpimon, but it was
elusive, and it's scaring me now! It wouldn't immediately show on live
stdout (the way the other touch-hotkeys, and normal keys, do), and I
even had trouble seeing it when trying to redirect stdout to a file!
Ctrl-C'ing would prematurely truncate the output, sometimes not
capturing it, even the more graceful Escape-exit wouldn't capture it
unless I waited or padded it with mouse movements. Ie. there is some
very weird delay going on, and maybe repetition, or something.

For example, I swear I only touched that info key 5 times here, and then
AFTERWARDS pressed the 'A' key twice, and then Esc. grep'ing for
'Type: 1' I was able to catch:

A more weird example, again I *swear* I first only touched that info key
*5* times, and then moved the mouse for a few seconds between 2 'A' key
presses, and finishing with Escape, but although it showed the two 'A'
key events properly, it also showed *11* "code 325" and 11 "code 330"
value1 events, out of order!?

Those events are touchscreen events, maybe your mouse is responsible for them.

I have to apologize, the events send by ACPI WMI to kacpimon do not contain a "PNP0C14" string
or the name WMI at all.

Instead they look like this:

	netlink:  9DBB5994-A997- 000000d0 00000000

Can you try to use kacpimon again but without root privileges? This way only netlink events show up.
You might also stop acpid while you are using kacpimon.

If you still cannot receive any netlink events, then i might need to take a look at your ACPI tables
via acpidump.

Thanks,
Armin Wolf

These warnings in dmesg are harmless, they are informing you that some WMI devices are unavailable.

I took a look at your ACPI tables and it seems that the WMI device used by hp-wmi is indeed unused.
What is the model name of your HP notebook?

Interesting.

There have been several attempts to add support for this
in the past. The last one being:

https://lore.kernel.org/platform-driver-x86/20220922182424.934340-1-lkml@vorpal.se/

Note that in this case this also required some vender
specific poking in toshiba_acpi to get things to work.

I see that the HP Compaq 8710p is about the same vintage
as the Toshiba Z830 on which the last attempt to do
something about the quick start buttons was done.

So this might very well explain the missing button issue.

Hans

I can try to upstream the necessary changes. But i cannot test the changes concerning the toshiba_acpi driver.
Would it be ok if i omit those changes?

Dennis, can you check that your device runs the latest BIOS? And if this is not the case, could you do a BIOS
update and send me an updated acpidump?

The reason for this is that currently, the button device receives only system wake events, but no button press
events during runtime. Maybe this is a BIOS bug, although this could also be intentional (fancy power button).

Hi,

while modifying the quickstart button driver to use the standard pm wake infrastructure, i have run into a
little problem: how to properly hook up the platform device with the ACPI device wakeup infrastructure?

Is this possible when using a platform driver, or do i need to use a ACPI driver?

Thanks,
Armin Wolf

If you can work on this that would be great.

I think that just compile testing them is fine.

> Would it be ok if i omit those changes?

I have a slight preference for keeping the Toshiba changes.

As discussed below these "quick start" buttons
normally are only intended to wake up the laptop
and then immediately on wakeup start a specific app
tied to the button (IIRC). But at least on the Toshiba
the toshiba_acpi driver's special "poke" of the firmware
makes the button also send events normally, so that it
can actually be used as a normal button.

IMHO the Toshiba code is helpful in documenting the need
for such a special code (maybe extend it with a comment?).

With all that said if you don't want to submit
the Toshiba part compile-tested only, then I understand
and you can omit it.

See above IIRC what was discussed last time this is
an intentional (mis)feature of these buttons. Chances
are there might be some workaround for this for HP too,
but that will likely be tricky to find.

I'm not sure what exactly you are looking for but I think the powerbutton
handling in: drivers/platform/x86/intel/hid.c (search for wakeup) may help ?

If that does not help can you point me to the lines of code in the old version
of the code which you are trying to adjust ?

I was /finally/ able to update my BIOS slightly, only with the latest
freedos image available, one version up ... there seems to be another
newer (2011) windows-only one that I'm not able to use.

No change.

Why do all the other "quick start" buttons work - I see their key press
events, albeit not through hp-wmi?

(I "hacked" the "latest" 2011 bios rom in, and although it reports being
a newer version and newer release date, acpidump is exactly the same.
dmidecode says it's the newer one though. No difference.)

Can someone roughly explain what's going on? :p On my HP Compaq laptop
all those "buttons" work, except that one "info" one. How are those keys
being emulated(?) as my regular keyboard? Why would only one not work?
