linux/drivers/input/evdev.c, branch v2.6.39

Input: evdev - indicate buffer overrun with SYN_DROPPED

2011-04-13T06:35:24Z

Add a new EV_SYN code, SYN_DROPPED, to inform the client when input events have been dropped from the evdev input buffer due to a buffer overrun. The client should use this event as a hint to reset its state or ignore all following events until the next packet begins.

Input: evdev - fix evdev_write return value on partial writes

2011-02-27T09:52:53Z

As was recently brought up on the busybox list (http://lists.busybox.net/pipermail/busybox/2011-January/074565.html), evdev_write doesn't properly check the count argument, which will lead to a return value > count on partial writes if the remaining bytes are accessible - causing userspace confusion. Fix it by only handling each full input_event structure and return -EINVAL if less than 1 struct was written, similar to how it is done in evdev_read.

Input: introduce device properties

2010-12-20T08:37:33Z

Today, userspace sets up an input device based on the data it emits. This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2

2010-12-15T07:55:21Z

The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while extending them to support large scancodes was a mistake. While we tried to keep ABI intact (and we succeeded in doing that, programs compiled on older kernels will work on newer ones) there is still a problem with recompiling existing software with newer kernel headers. New kernel headers will supply updated ioctl numbers and kernel will expect that userspace will use struct input_keymap_entry to set and retrieve keymap data. But since the names of ioctls are still the same userspace will happily compile even if not adjusted to make use of the new structure and will start miraculously fail in the field. To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly select the style of ioctls it wants to employ.
