[Linux Station] Install Module. modprobe

[felipe64]

I'm looking to find a way to plug my PS3 or PS4 controller/pad to my QNAP,

Following steps here : https://doc.ubuntu-fr.org/dualshock, i have to install module uinput.

using modprobe uinput doesn't install it.
Indeed, when i do cat /sbin/modprobe, the file has been customised by QNAP.

Code: Select all

#!/bin/bash

# only support one argument
result=$(qbus post com.qnap.qts/module [\"$0\", \"$1\"])
if [[ $result != *"\"code\": 200"* ]]; then
    echo "$result"
    exit 1
fi

How can i install a module on Linux Station?
Many Thanks,
Regards
Felipe

Hi guys!

I'm trying to accomplish the same thing (compiling "uinput" kernel module), but in my case is to make the Steam Controller work in Linux Station (Ubuntu 16.04).

I have tried with generic instructions like the ones outlined here, I have also followed the instructions left by @ouija in the thread about compiling the xpad module (but for the uinput one instead), taking into account @nikoss suggestions, but even if I'm able to build it, I'm still getting the following error when loading it:

Code: Select all

uinput: Unknown symbol kmem_cache_alloc_trace (err 0)

I have used the source code from QNAP available here, for QTS 4.3.X and Kernel 4.2.X, but the same happens... is there a more updated one available?

One thing I'm missing is using the "Module.symvers" file, but because I couldn't find it...

Any ideas would be very appreciated!

Best.

Thank you for your suggestions father_mande!!

I'll talk with support then and I'll try to put here the results

Hi Philippe is totaly right,

I already built this kernel module but never tested it, because i have no Joystick here (but at least insmod is loading them)

file is available here : www.qoolbox.fr/xpad_driver.tgz

Thank you QNAP_Stephane!!

I've tried that one and now it does not give an error, but it says instead:

Code: Select all

uinput: module is already loaded

So I guess it is already built in the Kernel? I couldn't find the "modules.builtin" file in the QNAP side, but I see this exists:

Code: Select all

[~] # ls /sys/module/uinput/      
uevent   version

But I don't see this on the Linux Station side.

The thing is that, even if it is already built in the kernel, the Linux Station is not able to use it. I've even tried with this user mode driver just for debugging purposes, and it is also not able to see the controller because the lack of the uinput module... Any ideas?

[QNAP_Stephane]

Linux Station should be binded to Kernel /dev on back side.. the LXC container must use it ( logically )

i guess .. /dev/uinput must exists, so might be working

[LaRseTe]

Hi again!

"/dev/uinput" indeep exists, but only on the "host" side, not on Linux Station. For it to exist also in Linux Station I have added this to the LXC container config:

Code: Select all

lxc.mount.entry = /dev/uinput dev/uinput none bind,optional,create=file

And after that I can see it inside the Ubuntu container, but it is still not detected by Steam nor by the sc-controller user mode drivers... I have tried giving all kind of permissions to it also, as I know is one of the problems some people have in the regular Ubuntu, but no luck. I'm getting out of ideas, but I'm sure is something obvious I'm not doing

[LaRseTe]

I think maybe I need to dig more into something like what is explained here: https://github.com/maruos/maruos/issues ... -240301821

[LaRseTe]

Thank you for your suggestions Philippe!

I've have tried that also, but still no luck.

I have the uinput built in kernel, it recognizes the dongle correctly as a HID device:

Code: Select all

[29915.336169] input: Valve Software Steam Controller as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/0003:28DE:1142.00C2/input/input144
[29915.388030] hid-generic 0003:28DE:1142.00C2: input: USB HID v1.11 Keyboard [Valve Software Steam Controller] on usb-0000:00:14.0-3/input0
[29915.390991] hid-generic 0003:28DE:1142.00C3: hiddev0: USB HID v1.11 Device [Valve Software Steam Controller] on usb-0000:00:14.0-3/input1
[29915.394157] hid-generic 0003:28DE:1142.00C4: hiddev0: USB HID v1.11 Device [Valve Software Steam Controller] on usb-0000:00:14.0-3/input2
[29915.396800] hid-generic 0003:28DE:1142.00C5: hiddev0: USB HID v1.11 Device [Valve Software Steam Controller] on usb-0000:00:14.0-3/input3
[29915.399620] hid-generic 0003:28DE:1142.00C6: hiddev0: USB HID v1.11 Device [Valve Software Steam Controller] on usb-0000:00:14.0-3/input4
[31169.441620] [usb.001.046] /sys/devices/pci0000:00/0000:00:14.0/usb1/1-3 added. (MTP mode)

I think I need to play more with "allow" with more devices like "usb", "input", etc

Will try when have more time and report back the results

[LaRseTe]

It is working now!

The thing that made it work was adding this to the LXC config file:

Code: Select all

lxc.mount.entry = /dev/bus/usb dev/bus/usb none bind,optional,create=dir

Steam now recognizes the controller when executed as root. If I execute it as normal user it crashes, even giving "uinput" permissions for all users. But I have to check a bit more because I have probably overconfigured everything, so I think I need to start over to find the minimum working configuration

I'll report back again once I find the time to do it right.

PS: Thanx all for your suggestions!

Hi Philippe is totaly right,

I already built this kernel module but never tested it, because i have no Joystick here (but at least insmod is loading them)

file is available here : www.qoolbox.fr/xpad_driver.tgz

Thanks for the files! These worked fo rme. I just put xpad.ko in

Code: Select all

/lib/modules/

and when I ran

Code: Select all

lsmod | grep xpad

(outside of Linux Station) it showed up there. This also allowed me to use my controller (Logitech F310) in HD Station with the RetroArch QPKG installed (see viewtopic.php?f=320&t=124292&hilit=retroarch). To get xpad working inside Linux Station, I added these lines to the linux station config file based on other users' instructions:

Code: Select all

lxc.mount.entry = /dev/bus/usb dev/bus/usb none bind,optional,create=dir
lxc.mount.entry = /dev/uinput dev/uinput none bind,optional,create=file

Then, I ran

Code: Select all

lsmod | grep xpad

inside Linux Station, and it appeared there as well, and the controller worked with RetroArch installed in Linux Station.
