Nice work, trying it out, but... #1

Open nhuillard opened 9 years ago

nhuillard commented 9 years ago

I'm trying this driver with a brand new Iris, back from LDLC (the first one had a problem with the battery, and appears to have had problems with the touchpad too, which prevented any further testing). I compiled and insmod the kernel module, and had the driver work for a few seconds (Debian Jessie with Gnome), until the pointer stopped just before reaching the upper left corner of the screen (it should have openned the "Activities" screen. I plugged-in an USB mouse, which worked right away, but the touchpad didn't work since then (gdm3 stop/start, rmmod/insmod, I even shutdown)... Are there any caveats while using it (as in "not compatible with an USB mouse" or "don't load usbmouse kernel driver" or anything else ?) I tried last summer to contact the Linux multitouch team, but was not able to provide a good USB trace. I don't know how your work is related to theirs, and maybe you have the information they need to make the existing multitouch driver work ? See http://lii-enac.fr/en/architecture/linux-input/multitouch-howto.html#force

Hi,

I'm sorry to ear that it does not completely work for you... Apart from the fact that the touchpad is shitty I don't have any problem on Linux Mint. Can you give me your kernel version ? (uname -a) and the output of a dmesg when the driver stops working ?

About the multitouch team, no I did not. The device appear not to be a HID device so no luck on this side. To get the driver working, I simply looked at the output when I used the device and mapped accordingly the device events to the kernel ones. I can use my driver with an usb mouse without any problems, they can't conflict because it is not the same device.

Let's first see what's the output of your dmesg and kernel version and from there we will see what's possible :)

I'm not in front of the computer as of now. From what I recall : kernel 3.16.7 from Debian Jessie, no dmesg output at all (except when I plug/unplug the USB mouse and other normal messages). Last time it stopped working, I was clearly trying to find the edge of the sensitive area, on the right : maybe this is the cause, and the edge is not at the exact same coordinates on every device ? Is there a way to debug the output of the device, or increase the verbosity of the driver ?

OK. Great.

I'll check that later. If you can also provide a way to increase the verbosity of the driver, or lead me to a USB debugging tool, it would be great.

Additional notes. The touchpad stops working when: double-finger-tap, tapping on the edge, fast moving maybe out of the sensing area, etc. Too many ways to stop it to be usable. Making the touchpad work again requires a reboot. rmmod/insmod is not sufficient, even with gdm3 restart (restarting the whole X server). Apparently, one of the /dev/input/ nodes is not removed/recreated when rmmod/insmod, whihc could be the problem (see notes above: /dev/input/by-id/usb-CNTouch_Touch_Device_V1.03-event-if02 and /dev/input/event10 are still dated 20:23 even though the module was reloaded at 20:34, as is /dev/input/by-id/usb-CNTouch_Touch_Device_V1.03-mouse) I'd really like to have this work... Many thanks for your work !

nhuillard commented 9 years ago

Forgot to mention: there is absolutely no dmesg output when the driver stops working. There are messages only when insmod/rmmod (see above, same as syslog contents).

daedric commented 9 years ago

Hi, Sorry for the late answer... Thanks for the dmesg, indeed this looks good and nothing seems to be out of the ordinary. It is quite strange all the problem you have, I wonder if it isn't more something related to X than the driver in itself. I'll compile a version with some debug for you to send me, in the meantime, would you mind to try out: sudo evtest and see if despite the mouse not moving you're still receiving events ?

If we can't figure out why it does not work I'll maybe install a debian to see if I can reproduce the bug.

Thanks,

daedric commented 9 years ago

The procedure to follow in case of the touchpad stop worklng is kindda nice, if you could do the same that would be awesome !

https://wiki.ubuntu.com/DebuggingTouchpadDetection

I forgot to answer about the /dev/input/inputX not being removed. This is normal and this is thanks to udev. It allows to assume one that once you plug something, it will keep its path.

nhuillard commented 9 years ago

Here is a first evtest.log file. I tried with and without X running, with the same result: the touch stops responding after some use (mostly touching in->out or out->in of the sensitive area, sometimes tapping). The exact simplest procedure is: reboot, gdm3 stop, insmod, evtest. This kind of confirm my initial idea, which was that your code may not work 100% with the Debian jessie kernel (Linux iris 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux), for some reason (interrupt handling, API change or so). Adding a lot a debug traces could help.

So evtest does not print anything when the trackpad stop responding ? I'll prepare a version with debug this afternoon.

daedric commented 9 years ago

Bad news, I upgraded my kernel to the 3.16.0 on my mint:

make -C /lib/modules/3.16.0-31-generic/build M=/home/daedric/work/cntouch_driver LDDINCDIR=/home/daedric/work/cntouch_driver/../include modules
make[1]: Entering directory `/usr/src/linux-headers-3.16.0-31-generic'
  CC [M]  /home/daedric/work/cntouch_driver/cntouch.o
  Building modules, stage 2.
  MODPOST 1 modules
  CC      /home/daedric/work/cntouch_driver/cntouch.mod.o
  LD [M]  /home/daedric/work/cntouch_driver/cntouch.ko
make[1]: Leaving directory `/usr/src/linux-headers-3.16.0-31-generic'

And it works perfectly fine.. So it does not look like a kernel incompatibility.

daedric commented 9 years ago

Can you try out the branch ?

$> git fetch origin
$> git checkout debug
$> make.......

Thanks!

Here is the result. Not that much...

I'll try to re-run this after I've uninstalled Virtualbox (and its vbox* kernel modules), because it is useless on this machine.

Question: does it still print something in logs when the mouse stop respnding on the screen ? In another terms, when the cursor does not respond but you try to move around, does it still print something in the logs ? Around the time it stops responding, is there anything aside the Data array entries ?

I checked once more: Command insmod ~/cntouch_driver-debug/cntouch.ko output (/var/log/syslog and dmesg):

Command evtest output is OK, and /var/log/syslog reflects the same output, ie.:

This is OK until the touchpad stops responding. When it stops responding, there is nothing more in evtest output and /var/log/syslog and dmesg. All logs just stop spitting anything related to the movements. I can confirm that the touchpad strops responding when I reach the edge of the sensitive area. I just tried to keep moving inside the sensitive area for a while and it kept working. This is a test without X (/etc/init.d/gdm3 stop). When I kill evtest (Ctrl+C):

If I try to reload the kernel module (insmod ~/cntouch_driver-debug/cntouch.ko), it does not respond anymore, until I reboot. I suspect either:

daedric commented 9 years ago

Hum, I need to think about this... I this log too many times: https://github.com/daedric/cntouch_driver/blob/debug/cntouch.c#L113 It should only printed on rmmod OR if you disable the touchpad (Fn + F1).

Since I reversed engineered the device maybe there is a case I did not handle and that would require some action from the driver to reset something. The problem is that I can't reproduce the problem on my end.

I wonder if it could still be a problem with your device. Did you test on windows ?

I check my bios asap but I don't think we can learn much

I didn't test using Windows, because I can't dual-boot this machine (no free space on the SSD). I tried Windows in a VirtualBox on the previous laptop, which had a motherboard problem. The touchpad didn't work in Windows either (I specifically tried to, and had a few events in Windows), but I can't say it was not because of the failed motherboard.

nhuillard commented 9 years ago

Did you have a chance to check your BIOS version ? Is there something else we can check ? I'd love to make this work here too ;-) Anyway, thanks for your efforts so far.

daedric commented 9 years ago

Sorry I was caught up on a shit-load of things. I did review all your comments and tried to make sense out of them, but not luck so far. If there is no oops/panic and nothing in the Xorg log that quite hard to debug and I'm far from being an expert. Worst thing is that I use it like everyday without a single problem. I'll check again the bios version but I do not believe that'll change anything. I'll also try to get the exact reference of my model so we can see if we actually have the same.

cheers,
