Hi,

can you share the output of "acpidump"? The zoom-out button
should
report KEY_ZOOMOUT, can you also share the output of dmesg
after loading the driver with the module parameter

Sorry i messed up and didn't use reply all, Im still quite
new to
this

That ok, mistakes happen :)

I think the reason for you problem with the zoom-out key is that
when sony-laptop
iterates through the list of possible key responses, it first
matches the definition
for SONYPI_EVENT_PKEY_P1 (0x20), which has the same key data as
SONYPI_EVENT_ZOOM_OUT_PRESSED (also 0x20).

This causes SONYPI_EVENT_PKEY_P1 to be picked instead of
SONYPI_EVENT_ZOOM_OUT_PRESSED.
That's right. The event mask is the same for programmable and
zoom
keys,
thus the conflict.

{ 0x05, SONYPI_PKEY_MASK, sonypi_pkeyev },
{ 0x05, SONYPI_ZOOM_MASK, sonypi_zoomev },

I am sending this mail to the maintainer of the sony-laptop
driver,
maybe he can help us in this case.
Heh... I actually have a UX ultra portable laptop somewhere (a
UX50
IIRC) but I'm not sure it'll even turn on. Those things are
like 15~20
years old now.

I don't quite remember the idiosyncrasies of this particular
model v/s
other models to be quite frank. On the other hand the module
has a
'mask' option that you can use to allow-list only certain sets of
events.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/platform/x86/sony-laptop.c?h=v6.9.5#n94



(I'm glad the help text says "see doc" because I don't see
this option
mentioned in the doc...)

The bitmasks are here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/platform/x86/sony-laptop.c?h=v6.9.5#n3365




Thanks for response but I'm bit confused now, since they have same
event, and i only allow the zoom in/out keys, won't I lose the
third
key? Am I missing something?

When using the "mask" module param, you will lose the third key.

I think the underlying issue could be that support for the
problematic 0x20 SONYPI_EVENT_PKEY_P1 was
added in commit 1cae71032183 ("sony-laptop: VGN-A317M hotkey
support"), while support for you VIAO model
was added in commit 3eb8749a3799 ("sony-laptop: add Type4 model").

Commit 1cae71032183 was added after commit 3eb8749a3799, so i think
it will be enough to introduce a
separate copy of sonypi_pkeyev[] without the conflicting 0x20
SONYPI_EVENT_PKEY_P1 definition.
This separate copy can then be used by the type3_events[]
definition
(which is used on you model).

If the maintainer agrees with this approach, i can create a
patch for
you to test. Are you able to
compile kernel modules on your device?

Thanks,
Armin Wolf

I am using opensuse on the device, I can just add patch in the
obs so
yeah rebuilding kernel is no issue, I could do the patch myself
but I
don't know how to make it device-specific.

Thanks for help!
Nice, can you test the attached patch and report back if it works?

Thanks,
Armin Wolf

Subject: [PATCH] platform/x86: sony-laptop: Fix
SONYPI_EVENT_ZOOM_OUT_PRESSED
   on Sony VAIO UX VGN-UX390N

It turns out that on type 3 models, the definitions for the
programmable
keys partially conflict with the definitions for the zoom keys.

This causes SONYPI_EVENT_ZOOM_OUT_PRESSED on the Sony VAIO UX
VGN-UX390N
to be reported as SONYPI_EVENT_PKEY_P1. Fix this by providing a
separate
definition for type3 models without the conflicting key entry.

Based on the commits you found, the conflicting event was added for
the
VGN-A series (a Type3 model). This change is effectively removing
the P1
button handling for them.

See 3eb8749a37990b505ab94466038c067444bbd7eb and later
e93c8a6819b217f4f4a490f67f26e02ff6b23b44: there used to be a Type4
model
that was meant to keep some of the events separate from Type3 models.
Perhaps reintroducing the distinction is going to serve us better in
this case?
The IRQ handler can be shared between Type3/4, but the events
can be in separate arrays, one for type3 and one for type4.

What do you think?

Sounds good, however there seem to be even more conflicting key
entries inside the type 3 key definitions.
Since you are the maintainer of the driver, i would prefer if you
would handle this.

Thanks,
Armin Wolf

Any progress so far?

Armin Wolf

Alternatively you could just swap the pkeysev lists based on the
former
type3/4 distinction, i.e.

+       pcidev = pci_get_device(PCI_VENDOR_ID_INTEL,
+                       PCI_DEVICE_ID_INTEL_ICH6_1, NULL);
+       if (pcidev) {
+               dev->control = &spic_types[2];
+               goto out;
+       }
+
+       pcidev = pci_get_device(PCI_VENDOR_ID_INTEL,
+                       PCI_DEVICE_ID_INTEL_ICH7_1, NULL);
+       if (pcidev) {
+               dev->control = &spic_types[3];
+               goto out;
+       }
+
+       pcidev = pci_get_device(PCI_VENDOR_ID_INTEL,
+                       PCI_DEVICE_ID_INTEL_ICH8_4, NULL);
+       if (pcidev) {
+               dev->control = &spic_types[3];
+               goto out;
+       }

(and maybe include also ICH9 as type4).

The output of `lspci` from the UX390 could also help making sure we
get
the right distinction.

       { 0x05, SONYPI_ZOOM_MASK, sonypi_zoomev },
       { 0x05, SONYPI_CAPTURE_MASK, sonypi_captureev },
       { 0x05, SONYPI_PKEY_MASK, sonypi_volumeev },
I am here to deliver!

Not sure which one you need so here are the main internal ones
(minus wifi
etc)

This is good. So ICH7, ICH8 and ICH9 would be type4, while ICH6 remains
