libudev-compatible interface for devd

Intended to work with xorg-server and libinput

Installation:

1. Install multimedia/v4l_compat port. In case of evdev-enabled kernels it can be patched to use system evdev headers instead of webcamd-supplied

2. Build and install libudev-devd

export CFLAGS=-I/usr/local/include export CPPFLAGS=-I/usr/local/include cd libudev-devd ./autogen.sh ./configure make && sudo make install

3. recompile x11-servers/xorg-server with DEVD port option disabled and following configure args added: --enable-config-udev=yes \ --disable-config-udev-kms --disable-systemd-logind

If you are going to use /dev/kbdmux0 as keyboard input device patch[1] should be applied to config/udev.c file in xorg distribution

4. Apply changes to xorg.conf

Remove all InputDevice from "ServerLayout" section of xorg.conf

For gsoc2014 evdev-enabled kernels add following lines to xorg.conf

<<< CUT

Use the libinput driver for all event devices

Section "InputClass" Identifier "evdev" Driver "libinput"

Driver "evdev"

MatchDevicePath "/dev/input/event*"

EndSection

Explicitly set xkb_rules to evdev for keyboards

Section "InputClass" Identifier "evdev keyboard" MatchIsKeyboard "on" MatchDevicePath "/dev/input/event*" Option "XkbRules" "evdev" EndSection

Disable kbdmux to not receive keyboard events twice

Section "InputClass" Identifier "evdev disable kbdmux" MatchIsKeyboard "on" MatchProduct "System keyboard multiplexer" MatchDevicePath "/dev/input/event*" Option "Ignore" "true" EndSection

<<<CUT

For stock kernels add following lines to xorg.conf

<<<CUT

Use the libinput driver for all event devices

Section "InputClass" Identifier "evdev" MatchDevicePath "/dev/input/event*" Driver "evdev" EndSection

Section "InputClass" Identifier "kbdmux" MatchDevicePath "/dev/kbdmux*" Driver "kbd" EndSection

Section "InputClass" Identifier "System mouse" MatchDevicePath "/dev/sysmouse" Driver "mouse" EndSection

Section "InputClass" Identifier "PS/2 mouse" MatchDevicePath "/dev/psm*" Driver "mouse" EndSection

Section "InputClass" Identifier "USB mouses" MatchDevicePath "/dev/ums*" Driver "mouse" EndSection

Section "InputClass" Identifier "Joystick" MatchDevicePath "/dev/joy*" Driver "mouse" EndSection

Section "InputClass" Identifier "Apple touchpad" MatchDevicePath "/dev/atp*" Driver "mouse" EndSection

Section "InputClass" Identifier "Wellspring touchpad" MatchDevicePath "/dev/wsp*" Driver "mouse" EndSection

Section "InputClass" Identifier "eGalax touchscreen" MatchDevicePath "/dev/uep*" Driver "egalax" EndSection

5. Fetch and install libinput port by Jan Kokemuller???

For gsoc2014 evdev-enabled kernels only:

fetch https://github.com/wulf7/libinput/archive/master.tar.gz tar zxvf master.tar.gz cd libinput-master ./autogen.sh make && sudo make install

6. Fetch and install xf86-input-libinput

For gsoc2014 evdev-enabled kernels only:

fetch http://xorg.freedesktop.org/releases/individual/driver/xf86-input-libinput-0.14.0.tar.bz2 .. .. ..

7. Build and install libudev-devd for Linuxolator

install devel/linux-c7-devtools, devel/autoconf and devel/automake than compile libudev.so library and install it somewhere under /compat/linux.

To build and install 64-bit library:

cd libudev-devd ./autogen.sh env CC="/compat/linux/bin/gcc" CFLAGS="--sysroot /compat/linux" ./configure --libdir=/usr/lib64/shims make sudo make install-exec DESTDIR=/compat/linux

To build and install 32-bit library:

cd libudev-devd ./autogen.sh env CC="/compat/linux/bin/gcc" CFLAGS="--sysroot /compat/linux -m32" ./configure --libdir=/usr/lib/shims make sudo make install-exec DESTDIR=/compat/linux

To run my_64bit_app or my_32bit_app with libudev overloaded with libudev-devd use

LD_PRELOAD=/usr/lib64/shims/libudev.so my_64bit_app

or

LD_PRELOAD=/usr/lib/shims/libudev.so my_32bit_app
