Hi All,

I've been running 4.16-rc7 on an XPS 9365 for some time and recently moved up to 4.17-rc5.
Immediately I noticed that i2c-hid devices (both touchscreen and touchpad) were not working.
Also when shutting the system down or rebooting it would just hang. (magic sysrq still worked).

I figured it was an easy to identify regression so I started a bisect but it came up with garbage
that ended in selftests shortly after 4.17-rc2.  I realized that's because is still will fail on 4.17-rc2
occasionally, seemingly after trying something newer and warm rebooting.
So it seems like it's "worse" after 4.17-rc2 (doesn't work at all) but semi reproducible on 4.17-rc2.

Not sure if I'm chasing some initialization race, but wanted to see if anyone else was running into this
or has some ideas?

#dmesg | grep 'i2c\|hid' doesn't show any obvious errors when in this state of non functional hid stuff.

I am reliably running a v4.17-rc3 with a merge on Jiri's tree on the 9360.

I doubt it's related to the event processing as I am not encountering
those issues.

It *could* be related to the interrupts not being properly raised.

Could you monitor /proc/interrupts and check if the ones associated
with your i2c-hid devices are increasing when you are using them?
Also, does the device emits raw HID events? (you can use hid-recorder
to check on the hidraw nodes.)

Cheers,
Benjamin

I checked both, /proc/interrupts isn't incrementing at all with the DLL077A:01 device.
Hid-recorder is showing output from the raw HID node.

Same thing for the touchscreen, no incrementing for it on the i2c_designware.0 device.

Something notable however;
When in this bad state hid-recorder didn't show /dev/hidraw1 for the touchscreen (which
Happens to be a Wacom touch screen).
It only showed /dev/hidraw0 for the touchpad.

Sorry, I couldn't get to it today. Monday is a public holiday here, so
I'll check on this Tuesday.

I don't really understand how the hidraw node can send data while the
interrupts are not raised.

Could you share the output of hid-recorder?

This explains why the touchscreen doesn't increment the interrupts.
Something I missed in the first email is that the hidraw0 node
disappear for the wacom device as the touchpad gets the hidraw0 name.

Could you provide the output  of a working kernel configuration of:
sudo hid-recorder /dev/hidraw*

This should provide me the whole logs at the same time of all the
hidraw nodes, and will allow me to reproduce the combination of
wacom/hid-multitouch you are experiencing.

Sure attached.
Note that I had a dock connected at the same time since I needed power.  This was
different than my previous tests.
That dock has 2 HID endpoints (so that might muddy this, I can re-capture if you need me to)

I was having a hard time getting it to work again with 4.17-rcX while trying
to capture this.
The only thing I got it to work with was when I turned off the touchscreen
In FW setup.

So I guess that means it's probably something Wacom race condition on
initialization since you noted the hidraw endpoint getting clobbered.

According to the file, this is the touchpad, and you draw a quick
circle on it. It's surprising the interrupts are not incrementing
because it clearly works fine.

Yeah. Sorry I should have been more precise. Ideally, could you try to
capture all the hidraw nodes at once on a working kernel (4.16 or
4.15)?
I shouldn't need the current broken behavior, just a description (with
some events) of the devices as they are supposed to be working.

Still, it's curious the wacom module disappear without any message.
Jason, did you experienced such issues with some of the integrated
wacom panels on v4.17-rc3 and later?

Thanks a lot for the logs.

I think I found it. It's a combination of two bugs actually:
- the first one is a race when we load hid-multitouch and wacom in
parallel. Both drivers will call __hid_bus_driver_added() which will
reprobe the devices if they are still marked as handled by
hid-generic. However, the test appears to not be concurrent safe so we
are rebinding twice the wacom device (one after loading wacom.ko, and
one after loading hid-multitouch.ko)
- the second issue is one we came to realize a few days ago with
Richard Hughes. The wacom driver suffers from a bug in power_supply
where you can not unbind it right after having bound it, because
power_supply_unregister() wait for the completion of its init work
which takes teh lock on the device. However, when you unbind a driver,
the lock is already help, so you have a dead lock.

I am not sure I'll found a solution for the second issue right now. I
can't reproduce it locally with my test kernel :(
For the first solution, it should be easy enough to add a locking
mechanism to be sure we are not unibinding twice the device.

Note that if we hadn't the second issue, the first one would only show
dmesg logs, but the device would be working :/

Cheers,
Benjamin
