* [PATCH] input: Add support for Wacom protocol 4 serial tablets
From: Hans de Goede @ 2014-07-19 16:38 UTC (permalink / raw)
To: Dmitry Torokhov; +Cc: Julian Squires, linux-input
Hi All,
Recent version of xf86-input-wacom no longer support directly accessing
serial tablets. Instead xf86-input-wacom now expects all wacom tablets to
be driven by the kernel and to show up as evdev devices.
This has caused old serial Wacom tablets to stop working for people who still
have such tablets. Julian Squires has written a serio input driver to fix this:
https://github.com/tokenrove/wacom-serial-iv
About a year ago Julian submitted this upstream, back then the response by
Dmitry was:
> The driver looks quite reasonable, however that would be the 4th Wacom
> driver in the tree... I wonder if it is time to split out transport
> parts from core wacom functionality so that it can be shared by USB, I2C
> and serio devices.
I've taken a quick look at this, the i2c driver is for touchscreens and in
the protocol has nothing in common with the other wacom drivers. The w8001
driver is for serial touchscreens and again a completely different protocol.
The wacom usb driver already deals with what appears to be a lot of different
protocol nuances, see for example wacom_wac.c, and non of all the different
package formats parsed in wacom_wac.c seem to have anything in common with
the wacom protocol 4 spoken over serial. So it seems that there is nothing
to be shared since these are really significant different devices which happen
to be from the same vendor. Moreover the usb wacom bits are being reworked
to use hid instead of to more or less parse usb hid reports themselves, and
I certainly don't want this driver to get in the way of that.
So all in all I believe it is best to keep this as a standalone driver.
Hence I'm hereby re-submitting this driver for upstream inclusion.
This is a significantly cleaned up version of the driver initially submitted
by Julian, with improved Graphire support (I own an old Graphire myself).
Regards,
Hans

That doesn't really make sense. If you're afraid of a device
generating spurious wakeup events when the lid is closed, you should
never enable it for wakeup. After all, one of the first things that
people often do after suspending their laptop is close the lid.

That's a fair point, and I think should be done by default. But that does not
change what Benson said - I think if we inhibited the device it should stay
inhibited across system suspend, including being disabled as wakeup source
even if it could be enabled as such.
Thanks,
Dmitry

This seems to be the best approach to me too.

Benjamin,
I think we might try to fix that [1] as well when making changes to the
sysfs entries. Currently every tablet connected wirelessly will trigger
creating new sysfs entries:
/sys/class/power_supply/wacom_ac
/sys/class/power_supply/wacom_battery
so sysfs is not happy about attempts to create duplicates. We need to
distinguish between devices using consecutive numbers or something else.

I do not believe it is nice to send -1 as pressure. What does it even

OK, fair enough, let's merge it. I sent out some questions in reply to
the patch itself.

We attempt to remove noise from coordinates reported by devices in
input_handle_abs_event(), unfortunately, unless we were dropping the
event altogether, we were ignoring the adjusted value and were passing
on the original value instead.

* [Problem] Samsung 700T1C Elan USB Touchpad not detected as touchpad
From: Daniel Heckenberg @ 2014-07-20 7:14 UTC (permalink / raw)
To: linux-input
Hello,
I'm experiencing the following issue which I'd like to help resolve.
Please let me know if there's any other information or action that I
can provide.
I'll send additional information in subsequent mails to avoid the
majordomo length block.
Many thanks,
Daniel
[1] Summary:
Samsung 700T1C Elan USB Touchpad not detected as touchpad
[2] Full description:
The Elan USB Touchpad (part of a USB keyboard / touchpad combo device)
used in the keboard dock for the Samsung 700T1C Ativ Tab Pro hybrid
laptop / tablet is not identified as a touchpad, but instead functions
only as a mouse.
This is clearly evident in X, where the input class driver matching
process fails to assign the "synaptics" driver as the
"matchIsTouchpad" predicate fails. Even if the "synaptics" driver is
directly assigned to the input device (/dev/input/event13 in this
case) with Option "protocol" "event", the synaptics driver fails to
communicate with the touchpad (see Xorg.0.log excerpt below).

Next, I shall:
- Remove HAS_IOMEM and NO_IOMEM from kernel, firstly.
- Try to make dummy IOMEM functions for score architecture.
- Continue discussing with UML for it.
By the way: how about HAS_DMA? can we treat it as HAS_IOMEM (remove
it from kernel)? (for me, I guess we can not).
At present, I shall finish sending patch for removing IOMEM today, and
continue to welcome any ideas, suggestions or completions for IOMEM or
DMA.
Thanks.

This needs to be last, otherwise lot's of stuff will break.

If you find sane dummy functions for both UML and score I'm fine with it.

Oh, sorry, I forgot, after remove IOMEM from kernel, also s390 and tile
need implement dummy IOMEM if !PCI.
If possible, I shall try to implement the dummy IOMEM in 'asm-generic',
and let uml, score, s390 and tile use them when they need.

For me, what you said is necessary, tile and s390 also need dummy IOMEM
when !PCI.
So for me, I shall implement them in "include/asm-generic", and let uml,
score, tile and s390 use dummy IOMEM when they need.
Welcome any other members ideas, suggestions and completions.
Thanks.

And sorry, I can not finish this discussion and send patch for it within
this week, for it is really a long necessary discussion.
But, hope we can finish this discussion and send patch for it within
this month (but in current condition, I am not quite sure).
And after finish discussion, welcome any other members help sending
related patch for it (e.g. implement dummy IOMEM in "asm-generic",
remove all IOMEM in kernel wide).
Thanks.

Result gets set to 0, or things like -ENODEV. So it should

Yes, e.g. take a look at wacom_wac.c line 53 .
I'll send a v2 with all other remarks fixed, thanks for the review.

* [PATCH v2] input: Add support for Wacom protocol 4 serial tablets
From: Hans de Goede @ 2014-07-20 14:46 UTC (permalink / raw)
To: Dmitry Torokhov; +Cc: Julian Squires, linux-input, Hans de Goede
Recent version of xf86-input-wacom no longer support directly accessing
serial tablets. Instead xf86-input-wacom now expects all wacom tablets to
be driven by the kernel and to show up as evdev devices.
This has caused old serial Wacom tablets to stop working for people who still
have such tablets. Julian Squires has written a serio input driver to fix this:
https://github.com/tokenrove/wacom-serial-iv
This is a cleaned up version of this driver with improved Graphire support
(I own an old Graphire myself).
Signed-off-by: Julian Squires <julian@cipht.net>
Signed-off-by: Hans de Goede <hdegoede@redhat.com>
--
Changes in v2:
-Drop text about MOUSEDEV from Kconfig help
-Drop broken URL from comment documenting the protocol
-Change a number of data types in struct wacom to more appropriate types

Some checkpatch errors should be ignored.
These are some of them.
This change doesn't make it easier to read
or to find any array entry.
It's currently in groups of 16 (0x10).
This change would make it very difficult
to find any particular entry.
It might make some sense to change the last
line to add a trailing " 0, 0" entry as
the compiler does to make it a bit clearer
the table has 128 entries.

* [RFC PATCH] Input: evdev - drop redundant list-locking
From: David Herrmann @ 2014-07-20 18:48 UTC (permalink / raw)
To: linux-input; +Cc: Dmitry Torokhov, Henrik Rydberg, David Herrmann
evdev->client_list is rcu-protected. There is no need to have a
separate spinlock just for the list. Either one is good enough, so lets
drop the spinlock.

Hi
I stumbled across this one when doing some evdev reviews. Maybe I'm missing
something obvious and I should stop coding on Sundays. But the RCU-protection
should be enough here, right?
We _could_ do a synchronize_rcu() during evdev_attach_client() to guarantee that
new events are really delivered once it returns. But that seems rather pedantic
to me.
I'm also not sure why we use RCU here, anyway. I mean, there's no high
contention so a spinlock should be fine and would get rid of the very expensive
synchronize_rcu during close(). But then again, I don't really care enough to
write benchmarks for that..
Thanks
David

RCU protection is for traversing list only, writes (as is adding and removing
elements from client_list) still have to be mutually exclusive.
Thanks.
