Hello,
My son wants to play games/flightgear on his FreeBSD laptop and I have
installed him a joystick THRUSTMASTER T-FLIGHT STICK X. The used software
stack is:
FreeBSD CURRENT r292778-amd64
Xorg 7.7.2 ...
uhidd-0.2.1_3
xf86-input-joystick-1.6.2_4.
all compiled from ports.
The essential lines of the configuration in xorg.conf are:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Joystick0" "SendCoreEvents"
EndSection
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/sysmouse"
Option "ZAxisMapping" "4 5 6 7"
EndSection
Section "InputDevice"
Identifier "Joystick0"
Driver "joystick"
Option "MatchIsJoystick" "on"
Option "Device" "/dev/uhid0"
Option "DebugLevel" "7"
Option "StartKeysEnabled" "True"
Option "StartMouseEnabled" "True"
Option "MapButton1" "button=1"
Option "MapButton2" "button=2"
Option "MapButton3" "button=3"
Option "MapButton4" "none"
Option "MapAxis1" "mode=relative axis=+1x deadzone=5000"
Option "MapAxis2" "mode=relative axis=+1y deadzone=5000"
Option "MapAxis3" "mode=relative axis=+1zx deadzone=5000"
Option "MapAxis4" "mode=relative axis=+1zy deadzone=5000"
Option "MapAxis5" "mode=accelerated axis=+1x deadzone=5000"
Option "MapAxis6" "mode=accelerated axis=+1y deadzone=5000"
Option "MapAxis7" "mode=none"
EndSection
...
The device /dev/uhid0 is there and gives data on move/buttons:
$ od -tx1 /dev/uhid0
0000000 00 f0 ff 80 3a 80 ff 00 00 00 00 01 02 00 00 00
0000020 00 00 00 00 f0 ff 4f 10 80 ff 00 00 00 00 01 02
0000040 00 00 00 00 00 00 00 f0 ff 42 2e 80 ff 00 00 00
...
But in Xorg.0.log it says about the device:

I re-compiled x11-drivers/xf86-input-joystick with additional logging
statements in
jstk.c
jstk_key.c
and it turned out that this initial sequence is not passed with success resulting
in jstk.c the return value of 11 (BadAlloc):
...
xf86Msg(X_CONFIG, "debug: doing jstkKeyboardHotplug() \n");
while(opts)
{
xf86Msg(X_CONFIG, "debug: %s %s \n", xf86OptionName(opts), xf86OptionValue(opts));
iopts = input_option_new(iopts,
xf86OptionName(opts),
xf86OptionValue(opts));
opts = xf86NextOption(opts);
}
/* duplicate attribute list */
attrs = DuplicateInputAttributes(pInfo->attrs);
rc = NewInputDeviceRequest(iopts, attrs, &dev);
input_option_free_list(&iopts);
FreeInputAttributes(attrs);
xf86Msg(X_CONFIG, "debug: jstkKeyboardHotplug() end with rc = %d\n", rc);
return (rc == Success) ? dev->public.devicePrivate : NULL;
}
The resulting additional "debug: ..." lines in Xorg.0.log are:
[ 7698.925] (**) debug: doing jstkKeyboardHotplug()
[ 7698.925] (**) debug: MatchIsJoystick on

In general, the port of xf86-input-joystick-1.6.2_4 is not well adopted
to FreeBSD, at least not its man page, which says: ...
The evdev(4) driver will suffice for those in most cases.
Do we have any evdev(4) driver in FreeBSD?
Anyway, how could I bring this to work?
Should I file a PR about this?
Thanks
matthias
