[PATCH 1/2] HID: Use multitouch driver for Type Covers

[Akihiko Odaki]

Use multitouch driver instead of microsoft one for Microsoft Surface
Type Covers.

By using MT_CLS_EXPORT_ALL_INPUTS, the keyboards function as well as
the multitouch pads do.

I've discussed this a couple of weeks back with Benjamin Tissoires, and
this patch would break the special keys (mute, brightness up/down,
keyboard backlight up/down and play/pause).

The recommended way to fix this was to move multi-touch processing into
the Microsoft driver, so that it would handle the trackpad's multi-
touch events.

You should be able to do this by carefully picking up the handling code
from hid-multitouch, or do something similar to what's done in hid-
wacom, which has the same problem as the Type Cover handling.

Can you confirm that this does indeed break those special keys? If it
does, it's a NAK from my side.

Cheers

For what it's worth the special keys on my keyboard work fine when
using this patch. I'm using a Surface Pro 3, Type Cover 3, running
GNOME and Fedora 23. The search, share, connect(?), and settings keys
are the only ones not mapped to anything out of the box, but they are
recognized by xev.

> The search, share, connect(?), and settings keys
I tested the patch again with xev and found that those "charm" keys
don't respond both on hid-microsoft and hid-multitouch, while other
keys respond. I'll have a further look.

Anyway, keys working with hid-microsoft also work with hid-multitouch,
so It's ready for merging, I think.

Re: [PATCH 1/2] HID: Use multitouch driver for Type Covers

[Akihiko Odaki]

The "Charm" keys seem to issue short-cut key combinations.
I also found Microsoft's document by searching for the combinations.

https://msdn.microsoft.com/en-us/library/windows/hardware/dn614461(v=vs.85).aspx

So the behavior of hid-multitouch is completely fine.

OK, so it looks like there was no need to use hid-microsoft for these covers.

However, I'd rather not add a full batch of the PIDs, but rather a
completed tested environment before migrating these covers from
hid-microsoft to hid-multitouch.

Can you restrict the patch to the covers you actually have and were
able to test?

Cheers,
Benjamin

All the multimedia keys work, and MT support also works, on my Surface
3 cover (045e:07de).

*But* the Caps-Lock key's LED doesn't light up anymore. Can you verify
it does on yours as well?

No, it doesn't work.

According to:
https://github.com/jimdigriz/debian-mssp4

Running "kbd_mode -u" afterwards would fix the Caps-Lock key not
working. I have no idea what the wider consequence of this would be
though[1].

Anything we can do in the kernel to have that working by default?

[1]: kbd_mode calls ioctl(fd, KDSKBMODE, K_UNICODE) with fd being the
console's fd.
