2011-10-03udev: make use of udev_enumerate_add_match_tag() only when it is availableLennart Poettering1-0/+4
udev_enumerate_add_match_tag() and udev_monitor_filter_add_match_tag() are mostly optimizations, hence simply skip these calls if they are not available in the installed version of libudev. This should fix the build on older versions of udev.

2011-08-22config: add udev/systemd multi-seat supportLennart Poettering1-0/+18
Add support for multi-seat-aware input device hotplugging. This implements the multi-seat scheme explained here: http://www.freedesktop.org/wiki/Software/systemd/multiseat This introduces a new X server switch "-seat" which allows configuration of the seat to enumerate hotplugging devices on. If specified the value of this parameter will also be exported as root window property Xorg_Seat. To properly support input hotplugging devices need to be tagged in udev according to the seat they are on. Untagged devices are assumed to be on the default seat "seat0". If no "-seat" parameter is passed only devices on "seat0" are used. This means that the new scheme is perfectly compatible with existing setups which have no tagged input devices. Note that the -seat switch takes a completely generic identifier, and that it has no effect on non-Linux systems. In fact, on other OSes a completely different identifier scheme for seats could be used but still be exposed with the Xorg_Seat and -seat. I tried to follow the coding style of the surrounding code blocks if there was any one could follow. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

Don't enumerate/monitor all devices of the system (since that can be quite a few), but limit our search to devices from the "input" subsystem, as well as the "tty" subsystem (to cover Wacom tablets).

2011-07-27config: process udev "changed" and "add" events in the same code pathsLennart Poettering1-5/+3
udev gives no guarantee that before each "changed" event for a device there's an "add" event, or that before each "remove" is an "add", or that before each "add" there was no "add" already and so on. Users can trigger these events at any time with "udevadm trigger", and netlink is a lossy transport, hence the events can come in unexpected ordering. With other words: regardless which event is generated, the X server must not choke on it and make the best of it, hence make sure that if we get an "add" event for an existing device we don't add the device a second time.

2010-09-01Fix udev population of Bluetooth input device product IDsChase Douglas1-17/+9
The udev device_added function takes the vendor and model IDs of added devices and converts them into an attribute that can be matched for by an InputClass configuration using MatchUSBID. Currently, the udev mechanism works for USB devices, but fails to work properly for Bluetooth devices. The product IDs of the event node are actually the IDs of the Bluetooth receiver instead of the device. This patch reads the product ID from the PRODUCT property of the parent of the added device. This tag is set correctly for both USB and Bluetooth input devices. The following devices have been tested by specifying individual InputClass sections in xorg.conf: * Apple Keyboard (Bluetooth) * Apple Magic Trackpad (Bluetooth) * Apple Magic Mouse (Bluetooth) * Microsoft Bluetooth Notebook Mouse 5000 (Bluetooth) * Microsoft IntelliMouse Optical (USB) * N-Trig Touchscreen (USB) * Wacom Bamboo Touch (USB) Signed-off-by: Chase Douglas <chase.douglas@canonical.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2010-05-25Add a "flags" field to DeleteInputDeviceRequest.Peter Hutterer2-2/+2
Some input drivers need to implement an internal hotplugging scheme for dependent devices to provide multiple X devices off one kernel device file. Such dependent devices can be added with NewInputDeviceRequest() but they are not removed when the config backend calls DeleteInputDeviceRequest(), leaving the original device to clean up. Example of the wacom driver: config/udev calls NewInputDeviceRequest("stylus") wacom PreInit calls NewInputDeviceRequest("eraser") NewInputDeviceRequest("pad") NewInputDeviceRequest("cursor") PreInit finishes. When the device is removed, the config backend only calls DeleteInputDeviceRequest for "stylus". The driver needs to call DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to clean up properly. However, when the server terminates, DeleteInputDeviceRequest is called for all devices - the driver must not remove the dependent devices to avoid double-frees. There is no method for the driver to detect why a device is being removed, leading to elaborate guesswork and some amount of wishful thinking. Though the input driver's UnInit already supports flags, they are unused. This patch uses the flags to supply information where the DeleteInputDeviceRequest request originates from, allowing a driver to selectively call DeleteInputDeviceRequest when necessary. Also bumps XINPUT ABI. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Dan Nicholson <dbn.lists@gmail.com> Signed-off-by: Keith Packard <keithp@keithp.com>
